WARNING
Electrostatic charging can lead to the crea-
tion of sparks and ignite fuel vapor. There is
a risk of fire and explosion.
Touch the metallic body of the vehicle
before you open the fuel filler cap or handle
the pump nozzle. Any possible electrostatic
charge present will in this way be depleted.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again. H
Environmental note
If fuels are handled improperly, they pose a
danger to persons and the environment. Do
not allow fuels to run into the sewage sys-
tem, the surface waters, the ground water or
into the ground.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify
a qualified specialist workshop and have the
fuel tank and fuel lines drained completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when adding fuel from a fuel
can. The fuel lines and/or the fuel injection system could otherwise be blocked by parti-
cles from the fuel can.

General notes
Important safety notes G
WARNING
If you switch off the ignition while 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. You 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
Mobile communications equipment distracts
the driver from traffic conditions. In addi-
tion, the driver could lose control of the
vehicle. There is a risk of an accident.
As a driver, use mobile communications
equipment only when the vehicle is at a
standstill.
As a vehicle occupant, use mobile communi-
cations equipment only in the designated
area, e.g. the rear passenger compartment. Observe the legal requirements of the country
in which you are driving. Some jurisdictions
prohibit the driver from using a mobile phone
while driving a vehicle.
Always use the hands-free system for tele-
phoning while driving. Only use the telephone
if road traffic conditions permit. If this is not
the case, pull over to a safe location before
using the telephone.
Bear in mind that at a speed of just 30 mph
(approximately

50 km/h), your vehicle is cov-
ering a distance of 44 feet (approximately
14 m) every second.
Drive sensibly – save fuel In order to save fuel, observe the following
tips:
X The tires should always be inflated to the
recommended tire pressure.
X Remove unnecessary loads.
X Remove roof carriers when they are not nee-
ded.
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 inter-
val display.
Fuel consumption also increases when driving
in cold weather, in stop-start traffic and in
mountainous terrain.
Overrun cutoff If you are in overrun mode and take your foot
off the accelerator pedal, the fuel supply is cut
off when the engine speed is out of the idle
speed control range.
Drinking and driving G
WARNING
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 judgment.
The possibility of a serious or even fatal
accident is greatly increased when you drink
or take drugs and drive. 140

WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery,
gases can escape from the battery. There is
a risk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
If the indicator/warning lamps do not light up
in the instrument cluster when temperatures
are low, it is probably because the discharged
battery has frozen. Should this be the case, do
not jump-start the vehicle or charge the bat-
tery. The service life of a thawed battery may
be shorter. Start-up behavior may deteriorate,
in particular at low temperatures. Have the 262
Battery

thawed battery checked at a qualified special-
ist workshop.
G
WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is
a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is suffi-
cient ventilation while charging and jump-
starting. Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of
injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention.
! Charge the installed battery only with a
charger approved for Mercedes-Benz. This
device allows the battery to be charged
while it is installed in the vehicle. The vehi-
cle's electronics system may otherwise be
damaged.
! Only charge the battery using the jump-
starting connection point.
A battery charger unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available as an
accessory. Only this device permits the charg-
ing of the battery in its installed position. Con-
tact an authorized Mercedes-Benz Commercial
Van Center for information and availability.
Read the operating instructions for your
charger before charging the battery.
Recharge the battery more frequently if you
use the vehicle mainly for short trips and/or
drive at low outside temperatures.

charger that has been tested and approved by
Mercedes-Benz, using the jump-start connec-
tion point in the engine compartment.
X Connect the battery charger to the positive
terminal and ground terminal in the same
order as when connecting the donor battery in the jump-starting procedure
(Y page
272).
i If a battery is not installed and not in ser-
vice, you should charge it every three
months. This will counter self-discharging
and prevent battery damage. Care
12 V battery !
Dirty battery clamps and battery surfaces
cause leak currents which lead to the bat-
teries discharging.
! Do not use cleaning agents containing
fuel. Cleaning agents containing fuel cor-
rode the battery housing.
! If dirt gets into the battery cell, battery
self-discharge will increase and the battery
may be damaged.
The following points on battery care must be
observed:
X Regularly check the battery terminals and
the fastening of the negative cable to the
chassis to ensure that they are firmly
seated.
X Always keep the battery terminals and bat-
tery surfaces clean and dry.
X Lightly grease the undersides of the battery
terminals with acid-resistant grease.
X Only clean the battery casing with a com-
mercially available cleaning product. Care
