For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLC Coupe have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Alfa Romeo Tonale doesn’t offer pretensioners for its rear seat belts.
The GLC Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Tonale doesn’t offer pre-crash pretensioners.
The GLC Coupe has standard NECK-PRO front head restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO front head restraints system moves the headrests forward to prevent neck and spine injuries. The Tonale doesn’t offer a whiplash protection system.
When descending a steep, off-road slope, the GLC Coupe’s standard Downhill Speed Regulation allows you to creep down safely. The Tonale doesn’t offer Downhill Speed Regulation.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The GLC Coupe has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Tonale doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the GLC Coupe and Tonale have rear cross-traffic warning, but the GLC Coupe has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Tonale’s Rear Cross-Path Detection doesn’t automatically brake.
Both the GLC Coupe and the Tonale have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available lane departure warning systems.
