CAUTION
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 smart entry & start system: Never attempt to remove the
key, as doing so will lock the steering wheel.
Vehicles with smart entry &
start system: To stop the
engine, press and hold the
“ENGINE START STOP”
switch for 2 consecutive sec-
onds or more, or press it
briefly 3 times or more in suc-
cession.
