objects, for example
There is a risk of fire and injury.
Always hold the cigarette lighter by the knob.
Always make sure that the cigarette lighter is
out of reach of children. Never leave children unattended in the vehicle.
Your attention must always be focused on the
traffic conditions. Only use the cigarette lighter when road and traffic conditions permit.

The sockets can be used for accessories with a
maximum draw of 180 W(15 A). Accessories
include such items as mobile phone chargers.
If you use the sockets for long periods when the engine is switched off, the battery may dis-
charge.
An emergency cut-off ensures that the on-boardvoltage does not drop too low. If the on-board
voltage is too low, the power to the sockets is
automatically cut. This ensures that there is suf-
ficient power to start the engine.

!
When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in a car wash
! Preferably use car washes with adjustable
high-pressure jets for pre-washing. This cor-
responds with the specifications for cabriolet
programmes. In car washes that use high
water pressures, there is a risk that a small
amount of water may leak into the vehicle.
! Make sure that the vehicle is not subse-
quently treated with hot wax.
! Make sure that:
R the side windows and sliding sunroof or
soft top are closed completely.
R the blower for the ventilation/heating is
switched off (OFF button is depressed).
R the windscreen wiper switch is at position
0.
The vehicle could otherwise be damaged.
! In car washes with a towing mechanism,
make sure that the automatic transmission is
in transmission position N; otherwise, the
vehicle could be damaged.
R Vehicles with DIRECT SELECT lever and
key:
do not remove the key from the ignition
lock. Do not open the driver's door or front- passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position Pauto-
matically and locks the wheels. You can
prevent this by shifting the automatic trans-
mission to Nbeforehand.
R Vehicles with DIRECT SELECT lever and
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 position Pauto-
matically and locks the wheels.
Observe the following to make sure that the
automatic transmission on vehicles with DIRECT
SELECT stays in position N:X
Make sure the vehicle is stationary and the
ignition is switched off.
X Turn the key to position 2in the ignition lock
(Y page 139).
Use the key instead of the Start/Stop button on vehicles with KEYLESS-GO.
X Depress the brake pedal and keep it
depressed.
X Shift the automatic transmission to position
N.
X Release the brake pedal.
X Release the parking brake.
X Switch off the ignition and leave the key in the
ignition lock.
You can wash the vehicle in an automatic car
wash from the very start.
Wash off excess dirt before cleaning the vehicle
in an automatic car wash.
After using an automatic car wash, wipe off wax
from the windscreen and the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windscreen.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements for each indi-
vidual country.
X Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft sponge to clean.
X Use a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
X Thoroughly hose down the vehicle with a gen-
tle jet of water.
X Do not point the water jet directly towards the
air inlet.
X Use plenty of water and rinse out the sponge
frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agent dry on the paint-
work.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible. 296
