Maintenance and care
Z

Do not remove the SmartKeyfromthe
ignition lock. Do not open the driver's
door or front-passengerdoor when the
engine is switched off. Otherwise, the
automatic transmission selects park
positionPautomatically and locks the
wheels. You can prevent this by shifting
the automatic transmission toN
beforehand.
RVehicles with KEYLESS-GO:
Do not open the driver's door or front-
passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park positionP
automatically and locks the wheels.
Observe the following to make sure that the
automatic transmission stays in positionN:
XMake sure the vehicle is stationary and the
ignition is switched off.
XTurn the SmartKey to position2in the
ignition lock (Ypage 147).
Use the SmartKey instead of the Start/
Stop button on vehicles with KEYLESS-GO.
XDepress and hold the brake pedal.
XShift the automatic transmission to
positionN.
XRelease the brake pedal.
XRelease the electric parking brake.
XSwitch off the ignition and leave the
SmartKey in the ignition lock.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
