235 Operation
Battery
Battery
The battery is located in front of the rear
seat bench and below the cup holder. Jump
starting terminals are located in the left
side of the engine compartment
(page 314). Refer to Service Booklet for
battery maintenance intervals.
The battery should always be sufficiently
charged in order to achieve its rated ser-
vice life.
If you use your vehicle less than approxi-
mately 200 miles (300 km) per month,
mostly for short-distance trips, or if it is not
used for long periods of time, you will need
to have the battery charge checked more
frequently and corrected if necessary.
When replacing batteries, always use bat-
teries approved by Mercedes-Benz.
If you do not intend to operate your vehicle
for an extended period of time, consult an
authorized Mercedes-Benz Light Truck
Center about steps you need to observe.Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
For more information, see “Battery”
(
page 311).
G
Observe all safety instructions
and precautions when handling
automotive batteries.
A
Risk of explosion
D
Keep flames or sparks away
from battery. Do not smoke.
B
Battery acid is caustic. Do not
allow it to come into contact
with skin, eyes or clothing.
In case it does, immediately
flush affected area with clear
water and seek medical help if
necessary.
E
Wear eye protection.
C
Keep children away.
F
Follow the instructions in this
Operator’s Manual.

240 OperationWinter driving
Winter drivingBefore the onset of winter, have your vehi-
cle winterized at an authorized
Mercedes-Benz Light Truck Center. This
service includes:

Check of anticorrosion and antifreeze
concentration.


Addition of cleaning concentrate to the
water of the windshield and headlamp
cleaning system. Add MB Concentrate
“S” to a premixed windshield washer
solvent/antifreeze which is formulated
for below freezing point temperatures
(page 339).


Battery test. Battery capacity drops
with decreasing ambient temperature.
A well charged battery helps to ensure
the engine can be started even at low
ambient temperatures.


Tire change. Mercedes-Benz recom-
mend M+S rated radial-ply tires with a
minimum tread depth of approximately 1⁄6in (4 mm) on all four wheels for the
winter season.
Winter tires
Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry
road conditions prevail. Use of winter tires
is the only way to achieve the maximum ef-
fectiveness of the ABS, ESP, EBB and
4-ETS in winter operation.
For safe handling, make sure all winter
tires mounted are of the same make and
have the same tread design.
Always observe the speed rating of the
winter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your ve-
hicle, you must place a notice to this effect
where it will be seen by the driver. Such no-tices are available at your tire dealer or any
authorized Mercedes-Benz Light Truck
Center.
Block heater (Canada only)
The engine is equipped with a block heat-
er.
The electrical cable may be installed at
your authorized Mercedes-Benz Center.
Warning!
G
Winter tires with a tread depth under
1⁄6in
(4 mm) must be replaced. They are no long-
er suitable for winter operation.
Warning!
G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Light Truck Center.

Mercedes-Benz Light Truck Center, you
can reset the service indicator yourself.
Switch ignition on.
The standard display of the control sys-
tem appears (

This message appears in the tachome-
ter:
SERVICE INTERVAL?
RESET WITH R BUTTON FOR 3 SEC.

To confirm, press reset button until you
hear a signal.
The service indicator now displays the
reset interval.
iIf the vehicle battery is disconnected,
the days of disconnection will not be in-
cluded in the count shown by the ser-
vice indicator. To arrive at the true
service deadline, you will need to sub-
tract these days from the days shown
in the service indicator.
Do not confuse the service indicator
with the engine oil level indicator :.
iIf the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Light
Truck Center correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next ser-
vice interval which will result in engine
damage not covered by the Mer-
cedes-Benz Limited Warranty.

Problem

Suggested solution
-
The yellow ABS indicator lamp
comes on while driving.
The ABS has switched off because charging
voltage has fallen below 10 volts. The battery
may not be charged.

Turn off unnecessary electric con-
sumers.
When the battery voltage is above this
value again, the ABS is operational
again.

Note the messages in the multifunc-
tion display (
page 260).

ESP
ESP
NOT AVAILABLE
The charging voltage has fallen below
10 volts and the ESP has switched off.

When the voltage is above this value
again, the ESP is operational again.

If necessary, have the generator (alter-
nator) and battery checked.
The ESP is deactivated because of a mal-
function or interrupted power supply. The
ABS and BAS might not be operational.
The system must be resynchronized.

Synchronize the ESP. With vehicle sta-
tionary and the engine running, turn
the steering wheel completely to the
left and then to the right to synchro-
nize the ESP.
If the ESP message does not go out:

Continue driving with added caution.

Visit an authorized Mercedes-Benz
Light Truck Center as soon as possi-
ble.
Failure to follow these instructions in-
creases the risk of accident.
!When synchronizing the ESP, make
sure you can turn the steering wheel in
both directions as far as it will go with-
out the wheels hitting any objects, e.g.
a road curb.
