2009 MERCEDES-BENZ CL COUPE keyless

R
Vehicles with a key:
Do not remove the key from the ignition
lock. Do not open the driver's or front-
passenger door when the engine is
switched off, as this automatically shifts
the automatic transmission to park posi-
tion Pand locks the wheels, unless you
have previously shifted the automatic
transmission to N.
R Vehicles with KEYLESS GO*:
Do not open the driver's or front-
passenger door when the engine is
switched off, as this shifts the automatic
transmission to park position Pand locks
the wheels.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is turned off and that the wind-
screen wiper switch is set to 0. Otherwise,
the rain/light sensor may be activated, trig-
gering unintended wiper movements. This
could cause damage to the vehicle.
After using an automatic car wash, wipe off
wax and drying agents from the windscreen
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windscreen.
High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle. Do not aim directly at any of the following:
R
tyres
R door joint
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
Damaged seals or electrical components
can lead to failures or leaks.
Matt finish care* Your vehicle has a clear matt finish. For this
reason, you should make sure that you
adhere to the following instructions to avoid
damage to paintwork due to improper treat-
ment.
! Under no circumstances should you pol-
ish the vehicle. Polishing will make the
paintwork shine.
! When caring for your paintwork, do not
use paint cleaner, grinding or polishing
products, or gloss preservers such as wax.
These products are only suitable for high-
gloss finishes. Using them on a vehicle with
a matt finish results in serious damage to
the surface (gleaming, spotted areas).
Always have paintwork repairs carried out
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
i From the range of available Mercedes-
Benz care products, use only the insect
remover and the car shampoo.
Cleaning the paintwork Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-308
