To obtain an accurate display of your com-
pass bearing, the correct geographical zone
must be set. If necessary, the compass must
also be calibrated (Y page 167).
If the compass is not calibrated or is malfunc-
tioning due to external interference, you will
see the Compass – – – message in the dis-
play.
i Large buildings, bridges, power lines or
large transmitting masts as well as metallic objects in or on the vehicle may interfere
with the compass display.

G
Risk of accident
Make sure that there is sufficient clearance
around the pedals when floormats are used,
and that the floormats are properly secured.
The floormats must be correctly secured at all
times using retainers and press-studs. Before you drive off, check the floormats and
secure if necessary. A floormat which is not
properly secured can slip and, thereby, inter-
fere with the movement of the pedals.
Do not place floormats on top of one another.

The infrared reflecting glass prevents the
vehicle interior from becoming too hot. It also
blocks radio waves up into the gigahertz
range. In order to operate radio-controlled equip-
ment (e.g. toll recording systems), areas :

! Refuel using only unleaded, sulphur-free
premium grade petrol with a minimum
octane number of 95 RON/85 MON con-
forming to European standard EN 228.
Otherwise, you could impair engine output
or damage the engine. i
As a temporary measure, only when the
recommended fuel is not available, you
may also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the quality of the avail-
able fuel may not be adequate and could
cause coking around the inlet valve. In such
cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Benz (part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.
Further information on "Fuel" (Y page 287). Diesel (EN 590, DIN 51628)
G
Risk of fire
Do not use petrol to refuel vehicles with a die-
sel engine. Never mix diesel with petrol. This
causes damage to the fuel system and engine
and could result in the vehicle catching fire.
! Refuel using only diesel which conforms
to European standard EN 590 or German
standard DIN 51628. Otherwise, you could
impair engine output or damage the engine.
! When refuelling vehicles with a diesel par-
ticulate filter in countries outside the EU,
only low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
(50 ppm) should be used.
! In countries in which diesel with a higher
sulphur content is available, the engine oil
should be renewed at more frequent inter-
vals. More information about intervals for
changing the engine oil can be obtained
from any Mercedes-Benz Service Centre.

Depending on driving style, the vehicle con-
sumes up to 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.
Checking the engine oil level Before checking the engine oil level the fol-
lowing conditions for the vehicle should be
met:
R the vehicle should be parked on level
ground.
R the engine should be switched off for at
least five minutes if the engine is at normal
operating temperature.
R the engine should be switched off for at
least 30 minutes if the engine is not at
operating temperature (i.e. if you only start
the engine briefly).
Using the on-board computer*
i Only possible on the GL 450 CDI 4MATIC.
On all other models, a dipstick is used to
check the engine oil level (Y page 177).

You will require considerably more effort to
steer and brake and you could therefore lose
control of the vehicle and cause an accident.
Brakes
G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Make sure that other road users are not
endangered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must select shift range 1,2or 3in good
time.
i This also applies if you have activated
cruise control, Speedtronic or Distronic*.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously.
Heavy and light loads If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the air-
flow to cool the brakes more quickly. G
Risk of accident
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet roads If driving in heavy rain for a prolonged period
of time without braking, there may be a
delayed reaction from the brakes when brak-
ing for the first time. You must brake harder.
You must therefore maintain a greater dis-
tance from the vehicle in front.
After driving on a wet surface, brake firmly
while paying attention to the traffic condi-
tions. This way the brake discs will become
warm, drying more quickly, which will protect
them against corrosion.
Limited braking performance on salted
roads
G
Risk of accident
The layer of salt on the brake discs and the
brake pads/linings may cause a delay in the
braking effect, resulting in a significantly lon-
ger braking distance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully, without put-
ting other road users at risk, when you are
driving on salted roads. This helps to
remove any salt that may have started to
build up on the brake discs and the brake
pads/linings.
R maintain a greater distance to the vehicle
ahead and drive with particular care.
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake disc. Driving tips

X
Wheels and tyres: check the tyre tread
depth and tyre pressure.
X Check for damage and remove foreign
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 Deactivate the LOW RANGE off-road gear
(Y page 114).
X Deactivate DSR (Y page 113).
X Set the differential lock setting to AUTO on
the selector wheel (Y page 116).
X Lower the vehicle level again to a level suit-
able to the road conditions, e.g. to the high-
way/high-speed level.
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/l
inings 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
