Engine cleaning
Prior to cleaning the engine compartment make sure to
protect electrical components and connectors from the
intrusion of water and cleaning agents.
Corrosion protection, such as MB Anticorrosion Wax
should be applied to the engine compartment after
every engine cleaning. Before applying, all control
linkage bushings and joints should be lubricated. The
poly-V-belt and all pulleys should be protected from any
wax.Ve h i c l e w a s h i n g
Do not use hot water or wash your vehicle in direct
sunlight. Use only a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo.
Thoroughly spray the vehicle with a diffused jet of
water. Direct only a very weak spray towards the
ventilation intake. Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clear water and thoroughly wipe dry with a
chamois. Do not allow cleaning agents to dry on the
finish.
Due to the width of the vehicle, prior to running the
vehicle through an automatic car wash, fold back the
outside mirrors to prevent them from getting damaged.
In the winter, thoroughly remove all traces of road salt
as soon as possible.
When washing the underbody, do not forget to clean the
inner sides of the wheels.

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.
Note:
For safety reasons, switch off wipers and remove
electronic key from steering lock before cleaning the
windshield, otherwise the wiper motor can suddenly
turn on and cause injury.Rear window cleaning
The corner flaps of the rear shelf partially cover the 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.

Prior to cleaning the inside of the rear window, operate
hardtop via the switch until rear shelf (1) is in a vertical
position. Leave key in steering lock position 2.
The roof will remain in this position for approximately
7 minutes, sufficient time for cleaning the inside of the
rear window.Wiper blades
Clean the wiper blade inserts with a clean cloth and
detergent solution.
Note:
For safety reasons, remove electronic key from starter
switch before cleaning the wiper blades, otherwise the
wiper motor can suddenly turn on and cause injury.
Light alloy wheels
Mercedes-Benz approved Wheel Care should be used for
regular cleaning of the light alloy wheels.
If possible, clean wheels once a week with
Mercedes-Benz approved Wheel Care, using a soft
bristle brush and a strong spray of water.
Follow instructions on container.
Note:
Use only acid-free cleaning materials. The acid could
lead to corrosion.

Headliner and shelf behind roll bars
Clean with soft bristle brush, or use a dry-shampoo
cleaner in case of excessive dirt.
Upholstery
Using aftermarket seat covers or wearing clothing that
have the tendency to give off coloring (e.g. when wet
etc.) may cause the upholstery to become permanently
discolored. By lining the seats with a proper
intermediate cover, contact-discoloration will be
prevented.
Leather Upholstery
Wipe leather upholstery with a damp cloth and dry
thoroughly or clean with Mercedes-Benz approved
Leather Care. Exercise particular care when cleaning
perforated leather as its underside should not become
wet.
Cloth Upholstery
Clean with soft bristle brush, or use a dry-shampoo
cleaner in case of excessive dirt.Seat belts
The webbing must not be treated with chemical
cleaning agents. Use only clear, lukewarm water and
soap. Do not dry the webbing at temperatures above
176°F (80°C) or in direct sunlight.
Wa r n i n g !
Do not bleach or dye seat belts as this may severely
weaken them. In a crash they may not be able to
provide adequate protection.
