Risk of accident and injury
Always have work on the vehicle carried out
by a qualified specialist workshop. In par-
ticular, work relevant to safety or on safety-
related systems as well as maintenance
work must be carried out at a qualified spe-
cialist workshop. The workshop must have
the necessary specialist knowledge and
tools to carry out the work required.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. G
Risk of accident and injury
Some safety systems only function when
the engine is running. You should therefore
never switch off the engine when driving.
Otherwise the safety systems of your vehi-
cle may not function correctly and as a
result will no longer protect you and other
persons as intended. In addition, there is a
risk that you may lose control of your vehi-
cle and thus cause an accident. G
Risk of accident and injury
Work carried out incorrectly, or alterations
made to the vehicle, e.g. rerouting of cables
under coverings, could cause the safety
systems of your vehicle to stop working
properly. The safety systems would thus no
longer protect you and other persons as
intended. In addition, there is a risk that you
may lose control of your vehicle and thus
cause an accident.
All work and alterations to the vehicle, e.g.
installations or modifications, should there-
fore be carried out at a qualified specialist
workshop. G
Risk of accident
If you drive over obstacles at high speed or
if the vehicle bottoms out in rough terrain,
it could cause heavy impacts to the vehicle
underbody, tyres or wheels. This could
cause your vehicle to be damaged, which in
turn might lead to an accident. This also
applies to vehicles which are equipped with
underbody protection.
You should therefore drive over obstacles
slowly and prevent the vehicle from bot-
toming out when driving off-road. If neces-
sary, have your vehicle inspected at a
qualified specialist workshop. G
Risk of accident
If work on electronic equipment and its
software is carried out incorrectly, this
equipment could stop working. The elec-
tronic systems are networked via interfa-
ces. Tampering with these electronic sys-
tems could cause malfunctions in systems
which have not been modified. Malfunc-
tions such as these can seriously jeopard-
ise the vehicle's operating safety and
therefore your own safety.
You should therefore have all work and
modifications to electronic components
carried out at a qualified specialist work-
shop. Vehicle registration
Mercedes-Benz may ask its Service Centres
to carry out technical inspections on certain
vehicles to improve their quality or safety.
If you did not purchase your vehicle from an
authorised specialist dealer and your vehicle
has never been inspected at a Mercedes-
Benz Service Centre, it is possible that your
vehicle is not registered in your name with
Mercedes-Benz. Mercedes-Benz can only
inform you about vehicle checks if it has your
registration data. Introduction

It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.
Inform Mercedes-Benz as soon as possible
about any change in address or vehicle own-
ership. Correct use
Observe the following information when using
your vehicle:
R The safety notes in this manual
R The "Technical data" section in this manual
R national road traffic regulations
R national road traffic licensing regulations G
Risk of injury
Various warning stickers are affixed to your
vehicle. Their purpose is to draw your atten-
tion, and the attention of others, to various
dangers. Therefore, do not remove any
warning stickers unless the sticker clearly
states that you may do so.
If you remove the warning stickers, you or
others could be injured by failing to recog-
nise certain dangers. Introduction

If the bonnet can be raised slightly, it is
not properly engaged. Open it again and
close it with a little more force. Engine oil
Depending on driving style, the vehicle con-
sumes a maximum of 0.8 l oil per 1,000 km.
The oil consumption may be higher than this
when the vehicle is new or if you frequently
drive at high engine speeds. You can only
estimate the oil consumption after you have
driven a considerable distance.
You will find further information about engine
oil in the "Technical data" section
(Y page 358).
Checking the engine oil level To do so:
R
the vehicle should be parked on level
ground.
R the engine should be switched off for at
least five minutes if the engine was at nor-
mal operating temperature.
R the engine should be switched off for at
least 30 minutes if the engine was not at operating temperature (i.e. if you only star-
ted the engine briefly).

X Wipe off oil dipstick 1.
X Insert oil dipstick 1into the oil dipstick
tube to the stop, and take it out again.
The oil level is correct if the level is between
minimum mark 3and maximum mark

Environmental note
When topping up the oil, take care not to
spill any. Oil must not be allowed to escape
into the soil or waterways. You would oth-
erwise be damaging the environment. Coolant
G
Risk of injury
The cooling system is pressurised. There-
fore, only unscrew the cap once the engine
has cooled down. The coolant temperature
gauge must display less than 70 °C. You
could otherwise be scalded by escaping hot
coolant.
Coolant consists of water and antifreeze/cor-
rosion inhibitor. Only check the coolant level
when the vehicle is on a level surface and the
engine has cooled down. Checking the coolant level The expansion tank is located in the engine
compartment on the right-hand side of the
vehicle when viewed in the direction of travel.

Tyres and wheels
226
i
An emergency spare wheel* may also be
fitted against the direction of rotation. MOExtended run-flat system*
The MOExtended run-flat system allows you
to continue driving the vehicle even when one
or more tyres lose all air pressure.
The MOExtended run-flat system may only be
used in conjunction with the tyre pressure
loss warning system or the tyre pressure
monitor* and on wheels specifically tested by
Mercedes-Benz.
i Vehicles with MOExtended run-flat sys-
tem are not equipped with the TIREFIT
kit* 27
.
It is therefore recommended to additionally
equip your vehicle with the TIREFIT kit*
when fitting tyres that do not feature run-
flat properties, e.g. winter tyres.
i A TIREFIT kit* is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre. You will find notes on driving with a flat tyre
in the "Practical advice" section
(Y
page 322). Tyre tread
G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3 mm.
You should thus replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4 mm or less because oth-
erwise they no longer provide adequate
grip.
R the tread on a tyre may not wear evenly.
You should thus regularly check the tread
depth and the condition of the tread
across the entire width of all tyres. If nec-
essary, turn the steering wheel so that
you can see the tyre tread more easily.
You could otherwise lose control of the
vehicle and cause an accident due to the
reduced grip of the tyres on the road. Tyre pressures
i You will find a table of tyre pressures for
various operating conditions on the inside
of your vehicle's fuel filler flap
(Y page 218).
The valid value for the spare wheel* is sta-
ted on the spare wheel and in the technical
data section. G
Risk of accident
Tyre pressure that is either too high or too
low has a negative effect on the vehicle’s
driving safety, which could lead you to
cause an accident. You should therefore
regularly check the pressure of all your
tyres (including the spare tyre*), particu-
larly prior to long trips, and correct the
pressure as necessary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. On vehicles fitted with the elec-
tronic tyre pressure monitor*, the tyre pres-
sure can be checked in the on-board com-
puter.

Trailer towing*
239G
Risk of injury
As soon as you raise the trailer drawbar, the
unladen vehicle rises slightly. The vehicle
then lowers to driving level.
Make sure that nobody is in the vicinity of
the wheel arch or the underbody. You could
otherwise trap yourself or others.
X Lift up the trailer drawbar and decouple the
trailer.
X Switch off the engine.
Vehicles with the AIRMATIC package*
X Make sure the selector lever is set to P.
X Depress the parking brake.
X Start the engine.
X Close the doors and tailgate.
X Secure the trailer against rolling away. G
Risk of injury
The vehicle is lowered as soon as you dis-
connect the trailer cable. Make sure that
nobody is in the vicinity of the wheel arch
or the underbody. You could otherwise trap
yourself or others.
As soon as you decouple the trailer, the
unladen vehicle rises slightly. Make sure that you or others are not injured in the
process.
X Remove the trailer cable and decouple the
trailer.
X Switch off the engine. Notes on towing a trailer
G
Risk of accident
When reversing the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R The permitted trailer drawbar nose-
weight
R The permitted trailer load R
The permitted rear axle load of the towing
vehicle
R The maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
You will find the applicable permissible val-
ues which must not be exceeded in the
vehicle documents.
You will find the values approved by the
manufacturer on the vehicle identification
plates and those for the towing vehicle in
the "Technical data" section.
You will find installation dimensions and loads
in the "Technical data" section
(Y page 354).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 85 kg.
However, the actual noseweight must not
exceed the value given on the trailer coupling
and trailer identification plates. The lowest
weight applies.
! Use a noseweight as close as possible to
the maximum permissible noseweight. Do
not use a noseweight of less than 50 kg,
otherwise the trailer may come loose. Operation
