Parking the vehicle for
along period
If you leave the vehicle parked for longer than
four weeks, the battery may be damaged by
exhaustive discharging.
X Connecting a trickle charger.
i You can obtain information about trickle
chargers from a qualified specialist
workshop.
If you leave the vehicle parked for longer than
six weeks, the vehicle may suffer damage as
a result of lack of use.
X Visit a qualified specialist workshop and
seek advice. Driving tips
General notes
Important safety notes G
WARNING
If you switch off the ignitio nwhile driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect.Y ou will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If you operate mobile communication
equipment while driving, you will be
distracted from traffic conditions. You could
also lose control of the vehicle. There is a risk
of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the
country in which you are driving. Some
jurisdictions prohibit the driver from using a
mobile phone while driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 feet (approximately 14 m)
per second.
Drive sensibly
–save fuel Observe the following tips to save fuel:
X
The tires should always be inflated to the
recommended tire pressure.
X Remove unnecessary loads.
X Remove roof carriers whe nthey are not
needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when
driving in cold weather, in stop-start traffic
and in hilly terrain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling 182

Raised level 20 in
(50 cm) R
Establish how deep the wate ris and the
characteristics of the body of water before
fording.
R Vehicles with the AIRMATIC package:
select the highest possible vehicle level.
R Restrict the shift range to 1or 2.
R Avoid high engine speeds.
R Enter and exit the water at a flat place and
at a steady walking pace.
R Drive slowly and at an even speed through
the water.
R Do not stop.
R Water offers a high degree of resistance,
and the ground is slippery and in some
cases unstable. Therefore, it is difficult and
dangerous to pull away in the water.
R Ensure that a bow wave does not form as
you drive.
R Clean any mud from the tire tread after
fording.
R Apply the brakes to dry them after fording. Winter driving
General notes G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents. Do not shift down for additional engine
braking on a slippery road surface.
G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open
a window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
i Vehicles with adiesel engine: do not
cover the radiator, e.g. with a protective
cover. The measuring function of the
onboard diagnosis syste mmay otherwise
provide inaccurate values .Some of these
values are required by law and must
therefore always be accurate.
Observe the notes in the "Winter operation"
section (Y page 400).
Driving with summer tires Observe the notes in the "Winter operation"
section (Y
page 400).
Slippery road surfaces G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking on a slippery road surface. 186

4MATIC (permanent four-wheel drive) If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic
conditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
! Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
! A function or performance test should
only be carried out on atwo-axle
dynamometer. Before you operate the
vehicle on such a dynamometer, please
consult a qualified workshop .You could otherwise damage the drive train or the
brake system.
4MATIC ensures that all four wheels are
permanently driven. Together with ESP ®
and
4ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to
insufficien tgrip.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
Further information about "Driving off-road"
(Y page 187).
DSR (Downhill Spee dRegulation) Important safety notes
DSR assists you when driving downhill. It
keeps the speed of travel at the speed set on
the on-board computer. The steeper the
downhill gradient, the greater the DSR
braking effect on the vehicle .When driving on
flat stretches of road or on an uphill gradient,
the DSR braking effect is minimal or
nonexistent.
DSR controls the set speed when it is active
and the automatic transmission is in the D,
R or Nposition. By accelerating or braking,
you can always drive at a higher or a lower
speed than that set on the on-board
computer.
Further information about "Driving off-road"
(Y page 187).
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor
override the laws of physics. DSR cannot take
account of road, weather and traffic
conditions. DSR is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
You are always responsible for keeping
control of the vehicle and for assessing
whether the downhill gradient can be
managed. DSR may not always be able to
keep to the set speed, depending on road 246
