Maintenance and care

Cleaning the plastic trim
G
WARNING
When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents
containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as a result, plastic
parts may break away and be thrown around
the interior when an air bag is deployed, which
may result in severe injuries.
! Do not affix the following to plastic
surfaces:
R stickers
R films
R scented oil bottles or similar items
You can otherwise damage the plastic.
! Do not allow cosmetics, insect repellent
or sunscreen to come into contact with the
plastic trim. This maintains the high-quality
look of the surfaces.
X Wipe the plastic trim with a damp, lint-free
cloth, e.g. a microfiber cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
The surface

may change color temporarily.
Wait until the surface is dry again.
Cleaning the steering wheel and gear or
selector lever X
Thoroughly wipe with a damp cloth or use
leather care agents that have been
recommended and

approved by Mercedes-
Benz.
Cleaning wooden trim and trim strips X
Wipe the wooden trim and trim strips with
a damp, lint-free cloth, e.g. a microfiber
cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz. !
Do not

use solvent-based cleaning agents
such as tar remover, wheel cleaners,
polishes or waxes. There is otherwise a risk
of damaging the surface.
! Do not use chrome polish for trim strips.
The trim strips 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 strips.
If the chrome-plated trim strips are very
dirty, you can use a chrome polish. If you
are unsure as to whether the trim strips are
chrome-plated or not, consult an
authorized Mercedes-Benz Center.
Cleaning the seat covers !
Do not use microfiber cloths to clean
genuine leather or artificial leather covers,
as these are too aggressive and, if used
often, may damage the cover.
! Observe the following when cleaning:
R clean genuine leather covers carefully
with a damp cloth and then wipe the
covers down

with a dry cloth. Make sure
that the leather does not become
soaked. It may otherwise become rough
and cracked. Only use leather care
agents that have been tested and
approved by Mercedes-Benz. You can
obtain these from a qualified specialist
workshop.
R clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dishwashing liquid).
R clean cloth covers with a microfiber cloth
moistened with a solution containing 1%
detergent (e.g. dishwashing liquid). Rub
carefully and always wipe entire seat
sections 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. Care

Towing and tow-starting
Important safety notes
G
WARNING
If circumstances require towing the vehicle
with all
wheels on the ground, always tow with
a tow bar if:
R the engine will not run
R there is a malfunction in the brake system
R there is a malfunction in the power supply
or the vehicle's electrical system
This is necessary to adequately control the
towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position 2.
If the SmartKey is left in starter switch
position 0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock,
remove SmartKey from starter switch and
reinsert.
It is better to have the vehicle transported
than to have it towed.
! You may only tow the vehicle a maximum
distance of 30 miles (50 km). A towing
speed of 30 mph (50 km/h) must not be
exceeded.
For towing distances over 30 miles
(50 km), the vehicle must loaded onto a
transporter.
! Only secure the tow cable or tow bar to
the towing eyes. You could otherwise
damage the vehicle.
! Do not tow with sling-type equipment.
This could damage the vehicle.
! Do not use the towing eyes for recovery
purposes 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. !
Your vehicles is equipped with an
automatic transmission. Therefore, you
must not

have the vehicle tow-started. The
transmission may otherwise be damaged.
If the transfer case can be shifted into neutral
N, you can tow the vehicle.
If the transfer case cannot be shifted into
neutral N, you can tow the vehicle with one
axle raised. Please bear the following in mind:
R remove the propeller shaft between the
transfer case and the rolling axle.
R turn the SmartKey to position 1 in the
ignition lock.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the SmartKey to position 2 in
the ignition lock
R cannot shift the automatic transmission to
position N

Snow chains
For safety reasons, Mercedes-Benz
recommends that you only use snow chains
that have been specially approved for your
vehicle by Mercedes-Benz, or are of a
corresponding standard of quality.
! Information about the use of snow chain
compatible AMG winter tires is applicable
for AMG tires. Use of snow chains is only
permissible with these tires.
! There is not enough space for snow
chains on some wheel sizes. Observe the
information under
"Tires and wheels" in the
"Technical Data" section to avoid damage
to the vehicle or the wheels.
R only use snow chains when driving on roads
completely covered by snow. Do not
exceed the maximum permissible speed of
30 mph (50 km/h). Remove the snow
chains as soon as possible when you are no
longer driving on snow-covered roads.
R local regulations may restrict the use of
snow chains. Applicable regulations must
be observed if you wish to mount snow
chains.
If you intend to mount snow chains, please
bear the following points in mind:
R you may not attach snow chains to all
wheel-tire combinations (Y page 266).
R mount snow chains only in pairs and only
on the rear wheels. Observe the
manufacturer's installation instructions.
! If snow chains are mounted on the front
wheels, the snow chains could grind
against the bodywork or components of the
chassis. This could result in damage to the
vehicle or the tires.
i You may wish to deactivate
ESP ®
(Y page 55) when pulling away with
snow chains mounted. This way you can
allow the wheels to spin in a controlled
manner, achieving an increased driving
force (cutting action). Tire pressure

WARNING
Follow
recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not

overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver's door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
You will find a table of recommended tire
pressures on the Tire and Loading
Information placard on the B-pillar on the
driver's side ( Y page 252). You will find a
table of tire pressures for various operating
conditions on the inside of your vehicle's fuel
filler flap. To test tire pressure, use a suitable tire
pressure gauge. The outer appearance of a
tire does not permit any reliable conclusion Tire pressure
