A warning sounds when the driver’s door is opened
while the key is in steering lock position 1 or 0.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
a nd-go tra ff ic. This preca ution h elps to avoid d ra ining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example: Heated seats, rear window
defroster.Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the key from the steering
lock. Do not leave the key in steering lock position 0.

cluster displayPractical hintsCar careIndex Headlamps, taillamps, turn signal lenses
Use a mild car wash detergent, such as Mercedes-Benz
approved Car Shampoo, with plenty of water.
To prevent scratches, never apply strong force and use
only a soft, non-scratchy cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry cloth or
sponge.
Window cleaning
Use a window cleaning solution on all glass surfaces. An
automotive glass cleaner is recommended.Rear window cleaning
The corner f la ps of t he rea r sh elf pa rtially cover t he rear
window. This prevents the window from being fully
cleaned with the hardtop closed.
Important!
Do not manually move corner flaps of rear shelf. Doing
so will result in damage to the roof folding mechanism
that is not covered by the Mercedes-Benz Limited
Warranty.
Renewed momentary operation of hardtop switch
extends the time by another 7 minutes.
Wa r n i n g !
If a warning sounds and the indicator lamp in the
hardtop switch blinks, immediately stop cleaning
and move back from window to prevent possible
injury.The hardtop is lowered into its storage
compartment.
