WARNING
■
If the engine has to be turned off while driving
●
Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
●
Vehicles without a smart entry & start system: Never attempt to remove
the key, as doing so will lock the steering wheel.
