Power washers G
WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect- edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
! Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
high-pressure cleaner nozzle. Information
about the correct distance is available from
the equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following:
R tires
R door gaps, joints etc.
R soft top
R wind deflector net
R electrical components R
battery
R plug-type couplings
R lights
R seals
R trim
R ventilation slots
Damaged seals or electrical components can
lead to leaks or failures.
! Vehicles with decorative film: parts of your
vehicle are covered with decorative film.
Maintain a distance of at least 27.5 in (70 cm) between the film-covered parts of the vehicle
and the nozzle of the power washer.
Information about the correct distance is
available from the equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
The water temperature of the power washer
must not exceed 140 ‡ (60 †).
! If the SmartKey is within the rear detection
range of KEYLESS-GO, the following situa-
tions, for example, could lead to the uninten-
tional opening of the trunk lid:

243Maintenance and care Z

!
Do not use chrome polish on trim pieces.
The trim pieces have a chrome look but are
mostly made of anodized aluminum and can
lose their shine if chrome polish is used. Use
a damp, lint-free cloth instead when cleaning the trim pieces.
If the chrome-plated trim pieces are very
dirty, you can use a chrome polish. If you are
unsure as to whether the trim pieces are
chrome-plated or not, consult an authorized
Mercedes-Benz Center.
X Wipe the trim elements with a damp, lint-free
cloth, e.g. a microfiber cloth.
X Heavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
Cleaning the seat covers General notes
! Do not use a microfiber cloth to clean covers
made out of real leather, artificial leather or
DINAMICA. If used often, these can damage
the cover.
i Note that regular care is essential to ensure
that the appearance and comfort of the cov-
ers is retained over time.
Genuine leather seat covers ! To retain the natural appearance of the
leather, observe the following cleaning
instructions:
R Clean genuine leather covers carefully with
a damp cloth and then wipe the covers
down with a dry cloth.
R Make sure that the leather does not
become soaked. It may otherwise become
rough and cracked.
R Only use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a qualified
specialist workshop.
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
R differences in the texture
R marks caused by growth and injury
R slight nuances of color
These are characteristics of leather and not
material defects. Seat covers of other materials
! Observe the following when cleaning:
R clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid).
R clean cloth covers with a microfiber cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid). Rub
carefully and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning results
depend on the type of dirt and how long it
has been there.
R clean DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions to avoid leaving visible lines.
Cleaning the seat belts G
WARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event of an accident. This poses an increased risk of
injury or fatal injury.
Never bleach or dye the seat belts.
! Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts by
heating at temperatures above 176 ‡(80 †)
or in direct sunlight.
X Use clean, lukewarm water and soap solution.
Cleaning the carpets X
Use the carpet and textile cleaning agents
recommended and approved by Mercedes-
Benz. 248

Secure the tow rope or tow bar to the towing
eye only. Otherwise, the vehicle could
become damaged.
! When Active Brake Assist, Active Distance
Assist DISTRONIC or the HOLD function is
activated, the vehicle brakes automatically in
certain situations.
To avoid damage to the vehicle, deactivate
these systems in the following or similar sit-
uations:
R when towing the vehicle
R in the car wash
! Do not use the towing eyes for recovery pur-
poses as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
! Shift the automatic transmission to position
005C and do not open the driver's or front-
passenger door when towing the vehicle
away. Otherwise, the automatic transmission may shift to position 005Dwhich can cause
damage to both vehicles.
! Do not tow with sling-type equipment. This
could damage the vehicle.
! You may tow the vehicle for a maximum dis-
tance of 30 miles (50 kilometers). A towing
speed of 30 mph (50 km/h) must not be
exceeded.
For towing distances over 30 miles
(50 kilometers), the entire vehicle must be
raised and transported.
! Observe the transmission fluid temperature
(AMG menu) in the on-board computer when
towing. The transmission oil temperature
must not exceed 250 ‡ (120 †). If this
occurs, you must stop towing immediately.
! Tow-starting the vehicle is not permitted.
The transmission may otherwise be damaged.
Also observe the following notes:
R If the engine does not start, try jump-starting
it (Y page 256). Tow-starting the vehicle is not
permitted.
R If it is not possible to jump-start the vehicle,
have it transported to the nearest qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Service Center. If the vehicle can no longer be driven because of
an accident or breakdown, you have the follow- ing options:
R Transporting the vehicle.
As a rule, you should have the vehicle trans-
ported.
R Towing the vehicle with a tow rope or tow bar.
Only tow the vehicle in exceptional cases. The
engine must be running if you tow the vehicle with a tow rope or tow bar.
If the vehicle has suffered transmission damage, have it transported on a transporter or trailer.
Observe the display messages in the instrument
cluster.
The battery must be connected and charged.
Otherwise, you:
R will not be able to switch on the ignition with
the Start/Stop button
R cannot start the engine
R cannot release the electric parking brake.
R cannot shift the automatic transmission to
position 005C
Disarm the automatic locking feature before the vehicle is towed (Y page 73). You could other-
wise be locked out when pushing or towing the
vehicle. Permitted towing methods
Mercedes-Benz recommends transporting your
vehicle in the case of a breakdown, rather than
towing it away.
When towing away, use a towing rope or a tow-
ing bar with both axles on the ground. Do not use any tow bar systems. Installing/removing the towing eye
Installing the towing eye The bracket for the screw-in towing eye is
behind the radiator trim.
