For enhanced safety, the front and middle seat shoulder belts of the Toyota Sienna are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes Metris Passenger doesn’t offer height-adjustable middle seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Sienna are reminded to check the back seat if they opened the rear door before starting out. The Metris Passenger doesn’t offer a back seat reminder.

The Toyota Sienna has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Metris Passenger doesn’t offer knee airbags.

The Sienna has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Metris Passenger doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The Sienna XLE/XSE/Limited/Platinum/25th Anniversary Edition has a standard Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Metris Passenger doesn’t offer backup collision prevention brakes.

The Sienna offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Metris Passenger doesn’t offer all-wheel drive.

The Sienna’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Metris Passenger.

The Sienna Platinum has a standard Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The Metris Passenger only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The Sienna has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Metris Passenger’s blind spot costs extra.

To help make backing out of a parking space safer, the Sienna has standard rear cross-path warning, helping the driver avoid collisions. Mercedes charges extra for Rear Cross-Traffic Alert on the Metris Passenger.

Both the Sienna and the Metris Passenger have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, collision warning systems, daytime running lights, rearview cameras and driver alert monitors.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Sienna its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 29 vehicles tested by the IIHS. The Metris Passenger has not been tested, yet.

Warranty

The Sienna comes with free roadside assistance for 2 years unlimited miles. Toyota will send help if you run out of gas, need a jump-start, lock your keys in or need any assistance on the road. Mercedes doesn’t give free roadside assistance for the Metris Passenger.

The Sienna’s 5 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Metris Passenger runs out after 100,000 miles.

Toyota pays for scheduled maintenance on the Sienna for 2 years and 25000 miles. Toyota will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the Metris Passenger.

There are over 3 times as many Toyota dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Sienna’s warranty.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Sienna’s reliability 33 points higher than the Metris Passenger.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Toyota vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Toyota above average in initial quality. With 17 more problems per 100 vehicles, Mercedes is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Toyota vehicles are more reliable than Mercedes vehicles. J.D. Power ranks Toyota above average in long-term dependability. With 34 more problems per 100 vehicles in the first three years of ownership, Mercedes is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Toyota vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Toyota first in overall reliability. Mercedes is ranked 24th.

Engine

The Sienna’s 2.5 DOHC 4-cylinder hybrid produces 37 more horsepower (245 vs. 208) than the Metris Passenger’s 2.0 turbo 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the Sienna gets better mileage than the Metris Passenger:

			MPG
Sienna
	FWD	2.5 4-cyl. Hybrid	36 city/36 hwy
	AWD	2.5 4-cyl. Hybrid	35 city/36 hwy
Metris Passenger
	RWD	2.0 turbo 4-cyl.	18 city/22 hwy

In heavy traffic or at stoplights the Sienna’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. The Metris Passenger doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Toyota Sienna uses regular unleaded gasoline. The Metris Passenger requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Toyota Sienna higher (7 out of 10) than the Mercedes Metris Passenger (6). This means the Sienna produces up to 1.1 pounds less smog-producing pollutants than the Metris Passenger every 15,000 miles.

Transmission

The Sienna has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Metris Passenger doesn’t offer a CVT.

Brakes and Stopping

For better stopping power the Sienna’s brake rotors are larger than those on the Metris Passenger:

	Sienna	Metris Passenger
Front Rotors	12.9 inches	11.8 inches
Rear Rotors	12.5 inches	11 inches

The Sienna’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Metris Passenger are solid, not vented.

Tires and Wheels

The Sienna XSE/FWD Platinum/25th Anniversary Edition’s tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Metris Passenger’s 55 series tires.

For better load carrying, ride, handling and brake cooling the Sienna XSE/FWD Platinum/25th Anniversary Edition has standard 20-inch wheels. The Metris Passenger’s largest wheels are only 17-inches.

Suspension and Handling

The Sienna has standard front and rear stabilizer bars, which help keep the Sienna flat and controlled during cornering. The Metris Passenger’s suspension doesn’t offer a rear stabilizer bar.

Passenger Space

The Sienna has .5 inches more front headroom, 4.5 inches more front legroom, .7 inches more front hip room, 4.1 inches more rear legroom, .7 inches more rear hip room and 2.9 inches more third row legroom than the Metris Passenger.

For enhanced passenger comfort on long trips the Sienna’s middle and third row seats recline. The Metris Passenger’s middle and third row seats don’t recline.

Cargo Capacity

The Sienna’s available rear seats fold to accommodate long and bulky cargo. The Metris Passenger doesn’t offer folding rear seats.

To make loading groceries and cargo easier when your hands are full, the Sienna’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Metris Passenger doesn’t offer a hands-free gesture to open its cargo door, forcing you to put cargo down if your hands are full.

Ergonomics

To help each driver find a more comfortable driving position, the Sienna Limited/Platinum/25th Anniversary Edition offers a telescoping steering wheel. Much better than just a tilt steering wheel or adjustable seat, this allows a short driver to sit further from the steering wheel while maintaining contact with the pedals. The Metris Passenger doesn’t offer a telescoping steering wheel.

The Sienna Limited/Platinum/25th Anniversary Edition’s standard easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Metris Passenger doesn’t offer an easy entry system.

The Sienna Platinum has a standard heads-up display that projects speed, tachometer and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Metris Passenger doesn’t offer a heads-up display.

The Sienna’s power parking brake sets with one touch and releases with one touch or automatically. The Metris Passenger’s parking brake has to be released manually.

The Pushbutton Start standard on the Sienna allows you to start the engine without removing a key from pocket or purse (Sienna XLE/XSE/Limited/Platinum/25th Anniversary Edition’s Smart Key System will also allow unlocking the doors and cargo door without taking your keys out). The Mercedes Metris Passenger doesn’t offer an advanced key system.

The Sienna’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Metris Passenger’s cruise control switches are unlit, making them difficult to find at night and operate safely.

To improve rear visibility by keeping the rear window clear, the Sienna has a standard rear wiper. A rear wiper costs extra on the Metris Passenger.

The Sienna’s LED headlights produce a whiter, brighter light (up to 3x) using five times less power than the Metris Passenger’s halogen headlights. LED lights also light instantly and last over twenty times longer than halogen.

While driving with high beams on, sensitive light sensors standard on the Sienna detect other vehicles which could be blinded and automatically switch to low beams. The Metris Passenger doesn’t offer automatic dimming high beams.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Sienna has standard extendable sun visors. The Metris Passenger doesn’t offer extendable visors.

Manual rear side window sunshades are available in the Sienna to help block heat and glare for the rear passengers. The Metris Passenger doesn’t offer rear side window sunshades.

The Sienna has standard power remote mirrors. The Metris Passenger only comes with remote mirrors at extra cost. Without them the driver will have to roll down the windows and reach across the car to adjust the mirrors.

The Sienna’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mercedes charges extra for heated mirrors on the Metris Passenger.

When the Sienna Limited/Platinum/25th Anniversary Edition is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Metris Passenger’s mirrors don’t automatically adjust for backing.

The Sienna’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Metris Passenger doesn’t offer the luxury of automatic dimming mirrors.

Both the Sienna and the Metris Passenger offer available heated front seats. The Sienna Platinum also has standard heated second row seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the Metris Passenger.

Standard air-conditioned seats in the Sienna Limited/Platinum/25th Anniversary Edition keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Metris Passenger doesn’t offer air-conditioned seats.

On extremely cold winter days, the Sienna Platinum’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The Metris Passenger doesn’t offer a heated steering wheel.

The Sienna has a standard center folding armrest for the middle row passengers. A center armrest helps make middle row passengers more comfortable and it can provide a boundary between children. The Metris Passenger doesn’t offer a middle row seat center armrest.

The Sienna has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the Metris Passenger.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Toyota Sienna offers an optional wireless phone charging system (Qi) in the center console. The Metris Passenger doesn’t offer wireless personal charging.

The Sienna (except LE) offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Metris Passenger doesn’t offer a house-current electrical outlet.
