2010 MERCEDES-BENZ G55AMG Adjust

Off-road driving rules
REngage the transfer case in position LOW
before driving under off-road conditions
( Y page 93).
R If necessary, activate differential locks
( Y page 95).
The ABS, BAS and ESP ®
are switched off
automatically when the differential locks
are activated.
R Fasten items being carried as securely as
possible ( Y page 129).
! Observe the following during off-road
driving:
R Keep doors, tailgate, windows, and tilt/
sliding sunroof closed whenever driving
off-road.
R Switch the cruise control off.
R Adjust vehicle speed to condition of
terrain. The more uneven, rutty and
steeper the terrain, the lower the speed
should be. Drive through water slowly at
an even speed, avoiding a bow wave.
R Be especially careful when driving in
unknown territory. It may be necessary
to get out of the vehicle and scout the
path you intend to take.
R Watch out for obstacles, such as rocks,
holes, tree stumps and ruts.
R Avoid excessive engine speeds – drive at
moderate engine speeds (max. 3 000
rpm).
R Before driving through water, determine
its depth.
R Do not stop vehicle while immersed in
water, and do not shut off the engine.
R In sandy soil, drive at a steady speed as
allowed by conditions. This helps
overcome the vehicle rolling resistance
and reduces the likelihood of the vehicle
sinking into the ground.
R Do not initiate jumps with the vehicle. It
interrupts the forward momentum of the
vehicle.
R Always drive onto slopes with the engine
running and the vehicle in gear.
R Do not shift automatic transmission into
neutral position N.
R Inspect the vehicle for possible damage
after each off-road trip.GWarning!
Do not reduce the tire inflation pressure
before driving through sand. However, if you
do so, remember to correct the tire inflation
pressure before continuing your trip. Driving
with reduced tire inflation pressure increases
the risk of losing control of the vehicle and
rolling over.
Checklist before off-road driving
Engine oil level
R Check the engine oil level ( Y page 153).
Only with a proper oil level can the vehicle
obtain a trouble-free oil supply, even on
steep gradients.
! If an engine oil level warning message
appears in the multifunction display while
driving, stop the vehicle in a safe location
or as soon at is safe to do so. Check the
engine oil level.
The engine oil level warning messages
should not be ignored. Extended driving
with the message displayed could result in
serious engine damage that is not covered
by the Mercedes-Benz Limited Warranty.
Tires
R Check the tread depth and maintain
specified tire inflation pressure. A placard

you pull over to a safe location and stop
before placing or taking a telephone call.
If you choose to use the telephone 9
while
driving, please use the hands-free device and
only use the telephone when road, weather
and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
mobile telephone while driving a vehicle.
Only operate the audio system or COMAND 9
(Cockpit Management and Data System) if
road, weather and traffic conditions permit.
Otherwise, you may not be able to observe
traffic conditions and could endanger yourself
and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
Emission control
Certain systems of the engine serve to keep
the toxic components of the exhaust gases
within permissible limits required by law.
These systems will function properly only
when maintained strictly according to factory
specifications. Any adjustments on the
engine should, therefore, be carried out only
by qualified Mercedes-Benz Center
authorized technicians.
Engine adjustments should not be altered in
any way. Moreover, the specified service
procedures must be carried out regularly
according to Mercedes-Benz servicing
requirements. For details refer to the
Maintenance Booklet.
GWarning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.
Maintenance
Notes
The Maintenance System in your vehicle
tracks the distance driven and the time
elapsed since the last maintenance service.
It calculates other maintenance service work
required, and calls for the next maintenance
service accordingly.
We strongly recommend that you have your
vehicle serviced at an authorized Mercedes-
Benz Center. Have it serviced in accordance
with the Maintenance Booklet at the times
called for by the maintenance service
indicator.
i Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times/mileage will result in
vehicle damage not covered by the
Mercedes-Benz Limited Warranty.
Maintenance service indicator
message
Information on maintenance work and
maintenance intervals are specified in the
Maintenance Booklet. Contact an authorized
Mercedes-Benz Center, or visit
www.mbusa.com (USA only) for additional
information.
The maintenance service indicator message
will notify you when the next maintenance
service is required.

and possibly a fire.
GWarning!
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.

If any of the following lamps in the instrument
cluster fails to come on during the bulb self-
check when switching on the ignition, have
the respective bulb checked and replaced if
necessary.
When you switch on the ignition, all lamps in
the instrument cluster come on. The low-
beam headlamp indicator lamp, high-beam
headlamp indicator lamp, and turn signal
indicator lamps will only come on if activated.

Replacing bulbs
Safety notes
Safe vehicle operation depends on proper
exterior lighting and signaling to a large
degree.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. Contact an
authorized Mercedes-Benz Center for
headlamp adjustment.
GWarning!
Bulbs and bulb sockets can be very hot. Allow
the lamp to cool down before changing a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you
Rtouch or move it when hot
Rdrop the bulb
Rscratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
iSince replacing bulbs is a technically
highly demanding process, we recommend
to have them replaced at an authorized
Mercedes-Benz Center.
iIf the headlamps or front fog lamps are
fogged up on the inside as a result of high
humidity, driving the vehicle a distance with
the lights on should clear up the fogging.

Bi-Xenon headlampGWarning!
Do not remove the cover for the Bi-Xenon
headlamp. Because of high voltage in Xenon
lamps, it is dangerous to replace the bulb or
repair the lamp and its components. It is
recommended to have such work done by a
qualified technician.
