MAINTENANCE AND SERVICING
512bering that it may not be as thorough as when you yourself go over the vehicle withsponge and water. Keeping the underbodyclean is most important, especially in the win-ter. Some automatic washers do not havefacilities for washing the underbody.
NOTE
Condensation may form temporarily on the inside of the lenses of exterior lights such asheadlights or taillights. This is normal and thelights are designed to withstand moisture.Normally, condensation will dissipate after thelights have been on for a short time.
CAUTION
When using an automatic car wash in which the vehicle has to be able to roll freely, theauto-hold brake function must be deactivated.If this is not done, the brakes will automati-cally be applied when the vehicle is stationary. To deactivate this function:
1. Drive the vehicle into the car wash
2. Turn off the auto-hold function using the
control on the center console
3. Turn off the parking brake's automatic function in the center display's Top view (tap
Settings, tap My CarElectric
Parking Brake and deselect Auto
Activate Parking Brake)
4. Put the gear selector in N
5. Switch off the ignition by turning the start knob to STOP and holding it in this posi-
tion for at least 4 seconds
The vehicle will then be able to roll freely.
CAUTION
• Before driving into an automatic car wash, turn off the optional rain sensor toavoid damaging the windshield wipers.
• Make sure that side view mirrors, auxiliarylamps, etc, are secure, and that anyantenna(s) are retracted or removed. Oth-erwise there is risk of the machine dis-lodging them.
• Chromed wheels:
Clean chrome-plated
wheels using the same detergents usedfor the body of the vehicle. Aggressivewheel-cleaning agents can permanentlystain chrome-plated wheels.
WARNING
• When the vehicle is driven immediately after being washed, apply the brakes,including the parking brake, several timesin order to remove any moisture from thebrake linings.
• Engine cleaning agents should not beused when the engine is warm. This con-stitutes a fire risk.
