Release the parking brake.
Shift the shift lever to N.
Vehicles without a smart key system: Turn the engine switch to the

STOP” switch to ACCESSORY (engine off) or IGNITION ON

do not pull out a vehicle that has fallen into a ditch.

stress on the emergency towing eyelets and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing .
● If the engine is not running, the power assist for the brakes a nd steering
