Both the K5 and Corolla have child safety locks to prevent children from opening the rear doors. The K5 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Corolla’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
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 K5 are reminded to check the back seat if they opened the rear door before starting out. The Corolla doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The K5 EX/GT1 has standard Parking Collision Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Corolla doesn’t offer backup collision prevention brakes.
The K5 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Corolla doesn’t offer all-wheel drive.
The K5 EX/GT1 has a standard Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The Corolla only offers a rear monitor.
The K5 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 and moves the vehicle back into its lane. A system to reveal vehicles in the Corolla’s blind spot costs extra.
To help make backing out of a parking space safer, the K5 has standard Rear Cross-Traffic Collision Warning and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. Toyota charges extra for Rear Cross-Traffic Alert on the Corolla and the Corolla’s Rear Cross-Traffic Alert does not include automatic braking.
Both the K5 and the Corolla have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.
