Engine compartment
159Engine 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 279).
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). Via the on-board computer
i
Only possible on the G 55 AMG. On all
other models, a dipstick is used to check
the engine oil level (Y page 160).
X Make sure that the key is in position 2in
the ignition lock (Y page 59).
X Press konce on the multi-function
steering wheel. The measurement takes a few seconds. You
will see one of the following messages in the
display:
R
Engine oil level OK
R Add 1.0 litre to reach maximum oil
level R
Add 1.5 litres to reach maximum oil
level
R Add 2.0 litres to reach maximum oil
level
X Top up the oil if necessary ( Ypage 160).
Other messages in the multi-function dis-
play
If the engine is at normal operating tempera-
ture and there is too much oil, you will see the
following message: Eng. oil level

X Screw cap 1onto the filler neck. H
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. Oil level in the automatic transmis-
sion
There is no need for you to check the oil level
in the automatic transmission. In the event of
oil loss or problems with gearshifts, have the
automatic transmission checked at a quali-
fied specialist workshop, e.g. at a Mercedes-
Benz Service Centre. Coolant
G
Risk of injury
The cooling system is pressurised. There-
fore, only unscrew the cap once the engine
has cooled down. This means 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.

Cap
X Slowly turn cap 1by half a turn in the
direction of the arrow to release excess
pressure.
X Unscrew cap 1completely and remove it.
X Turn cap 2further anti-clockwise and
remove it.
There is sufficient coolant in the expansion
tank if the coolant is level with the mark in
the expansion tank when the coolant is cold
or approximately 1.5 cm higher when hot. Operation

Tyres and wheels
163
!
Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage. G
Risk of accident
If wheels or tyres other than those which
have been tested are fitted:
R the brakes or chassis components could
be damaged.
R wheel and tyre clearances can no longer
be guaranteed.
This could cause an accident.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle. Notes on selecting, fitting and replacing
tyres R
only fit tyres and wheels of the same type
and make.
R only fit tyres of the correct size onto the
wheels.
R after fitting new tyres, run them in at mod-
erate speeds for the first 100 km as they
only reach their full performance after this
distance.
R fit new tyres on the front wheels first if tyres
of the same size are required on the front
and rear wheels.
R replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel.
R do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
! Store tyres that are not being used in a
cool, dry and preferably dark place. Protect
the tyres against oil, grease, petrol and die-
sel. Notes on regularly inspecting wheels
and tyres R
regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bumps on tyres and deforma-
tion, cracks or severe corrosion on wheels),
at least every 14 days, as well as after driv-
ing off-road or on rough roads. Damaged
wheels could cause a loss of tyre pressure.
R regularly check the tyre tread depth and the
condition of the tread across the whole
width of the tyre (Y page 164). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R all wheels must have a valve cap to protect
the valve against dirt and moisture.
R regularly check the pressure of all your
tyres including the spare tyre, particularly
prior to long trips, and correct the pressure
as necessary (Y page 164).
Notes on driving R
while driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective, Operation

Off-road driving
174
i
Information about retrofitting special all-
terrain tyres is available from any
Mercedes-Benz Service Centre.
Checklist before driving off-road X
Engine oil level: check the engine oil and
top it up if necessary.
Only then does the engine receive enough
oil when the vehicle is standing on a steep
incline.
X Vehicle toolkit: check that the jack is
working and make sure you have the wheel-
brace, a robust tow cable and a folding
spade in the vehicle.
X Wheels and tyres: check the tyre tread
depth and tyre pressure.
X Check for damage and remove any objects,
e.g. small stones, from the wheels/tyres.
X Replace any missing valve caps.
X Replace dented or damaged wheels.
Checklist after driving off-road Driving over rough terrain places greater
demands on your vehicle than driving on nor-
mal roads. After driving off-road, check the
vehicle. This allows you to detect damage
promptly and reduce the risk of an accident
to yourself and other road users. X
Shift the transfer case to HIGH
(Y page 93).
X Disengage the differential locks
(Y page 95).
X Clean the headlamps and rear lights and
check for damage.
X Clean the front and rear licence plates.
X Clean the wheels/tyres with a water jet and
remove any foreign objects.
X Clean the wheels, wheel arches and the
vehicle underside with a water jet; check
for foreign objects and damage.
X Check whether twigs or other parts of
plants have become trapped. These
increase the risk of fire and can damage
fuel pipes, brake hoses or the rubber bel-
lows of the axle joints and propeller shafts.
X After the trip, examine without fail the
entire undercarriage, wheels, tyres, brakes,
bodywork structure, steering, chassis and
exhaust system for damage.
X After driving for extended periods across
sand, mud, gravel, water or in similarly dirty
conditions, have the brake discs, wheels,
brake pads /linings and axle joints checked
and cleaned.
X If you detect strong vibrations after off-road
travel, check for foreign objects in the
wheels and drive train and remove them if necessary. Foreign objects can disturb the
balance and cause vibrations. Travelling uphill
