Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:
Keep tires at the recommended infla-
tion pressures.
Remove unnecessary loads.
Remove roof rack when not in use.
Allow engine to warm up under low
load use.
Avoid frequent acceleration and decel-
eration.
Have all maintenance work performed
at the intervals specified in the Service
Booklet and as required by the FSS.
Contact an authorized Mercedes-Benz
Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly country.
Drinking and driving
PedalsPower assistance
Warning!
G
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgement.
The possibility of a serious or even fatal ac-
cident 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.
Warning!
G
Keep driver’s foot area clear at all times. Ob-
jects stored in this area may impair pedal
movement.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle.

284OperationVehicle care
Vehicle careCleaning and care of vehicle
While in operation, even while parked, your
vehicle is subjected to varying external in-
fluences which, if gone unchecked, can at-
tack the paintwork as well as the
underbody and cause lasting damage.Such damage is caused not only by ex-
treme and varying climatic conditions, but
also by:
Air pollution
Road salt
Tar
Gravel and stone chipping
To avoid paint damage, you should imme-
diately remove:
Grease and oil
Fuel
Coolant
Brake fluid
Bird droppings
Insects
Tree resins, etc.
Frequent washing reduces and / or elimi-
nates the aggressiveness and potency of
the above adverse influences.More frequent washings are necessary to
deal with unfavorable conditions:
near the ocean
in industrial areas (smoke, exhaust
emissions)
during winter operation
You should check your vehicle from time to
time for stone chipping or other damage.
Any damage should be repaired as soon as
possible to prevent corrosion.
In doing so, do not neglect the underbody
of the vehicle. A prerequisite for a thor-
ough check is a washing of the underbody
followed by a thorough inspection. Dam-
aged areas need to be re-undercoated.
Your vehicle has been treated at the facto-
ry with a wax-base rustproofing in the body
cavities which will last for the lifetime of
the vehicle. Post-production treatment is
neither necessary nor recommended by
Mercedes-Benz because of the possibility
of incompatibility between materials used
in the production process and others ap-
plied later.
Warning!
G
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the partic-
ular container. Always open your vehicle’s
doors or windows when cleaning the inside.
Never use fluids or solvents that are not de-
signed for cleaning your vehicle.

Warning!
G
Failure to follow these instructions can re-
sult in severe injury or death.
Never lean over batteries while connecting,
you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.Warning!
G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof battery only to avoid the risk
of acid burns in the event of an accident.
!Never loosen or detach battery termi-
nal clamps while the engine is running
or the SmartKey is in the starter switch.
Otherwise the alternator and other
electronic components could be se-
verely damaged.
Have the battery checked regularly by
an authorized Mercedes-Benz Center.
Refer to Service Booklet for mainte-
nance intervals or contact your autho-
rized Mercedes-Benz Center for further
information.Warning!

350 Practical hintsBatteryReconnecting the battery
Turn off all electrical consumers.
Connect the positive lead and fasten its
cover 4.
Connect negative lead3.Batteries contain materials that can harm
the environment if disposed of improperly.
Large 12-volt storage batteries contain
lead. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.!Never invert the terminal connections.!The battery, its filler caps and the vent
tube must always be securely installed
when the vehicle is in operation.
iThe following procedures must be car-
ried out following any interruption of
battery power (e.g. due to reconnect-
ing):
Set the clock (see COMAND opera-
tor’s manual).
Resynchronize the ESP
(page 303).
Resynchronize side windows
(page 190).
Resynchronize sliding/pop-up roof
(page 194).
