outlet in front passenger footwell or rear cargo
compartment.
6. Start the engine and switch on the air pump.
7. Operate air pump (approximately 8 minutes) until
pressure gauge displays 61 psi (4.2 bar).
8. Switch off air pump and turn off the engine.
9. Unscrew filler hose from space-saver tire. Reinstall
tire valve cap.
Note:
Excessive tire air pressure should be released using the
vent screw.

Wa r n i n g !
When working on the vehicle with the engine
running, always set the parking brake in addition
to shifting the gear selector lever to position “P”.Wa r n i n g !
To prevent possible injury when unscrewing air
pump filler hose from space-saver tire valve after
inflating the tire, use a rag since the tire valve
could be hot.

Tire inflation pressure
A table (see fuel filler flap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approximately 1.5 psi (0.1 bar)
per 18°F (10°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage –
especially in the winter.
Example:
If garage temperature = approximately +68°F (+20°C)
and ambient temperature = approximately +32°F (0°C)
then the adjusted air pressure = specified air pressure
+3 psi (+0.2 bar).Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.
An underinf lated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread
separation, bulging etc.. Regular tire pressure checks
(including the spare tire) at intervals of no more than
14 days are therefore essential.

251 Battery
Te ch n ica l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index If a tire constantly loses air, it should be inspected for
damage.
The spare tire should be checked periodically for
condition and inflation. Spare tire will age and become
worn over time even if never used, and thus should be
inspected and replaced when necessary.Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the engine
compartment.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.
Wa r n i n g !
Do not overinflate tires. Overinflating tires can
result in sudden deflation (blowout) because they
are more likely to become punctured or damaged
by road debris, potholes etc.. Follow recommended
inflation pressures.Do not overload the tires by exceeding the specified
vehicle capacity weight (as indicated by the label
on the driver’s door latch post). Overloading the
tires can overheat them, possibly causing a
blowout.
Wa r n i n g !
Failure to follow these instructions can result 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..

When the connection is established, the message
“ROADSIDE ASSISTANCE – CALL CONNECTED”
appears in the MCS display. The Tele Aid system will
transmit data generating the vehicle identification
number, model, color and location (subject to
availability of cellular and GPS signals).
While the call is connected, you can change to
navigation menu by pressing NAVI button on the MCS.
A voice connection between the Roadside Assistance
dispatcher and the occupants of the vehicle will be
established. When a voice connection is established the
audio system mutes and the message “TELE AID –
ROADSIDE ASSISTANCE CALL ACTIVE” appears in the
MCS display. The nature of the need for assistance can
then be described. The Mercedes-Benz Roadside
assistance dispatcher will either dispatch a qualified
Mercedes-Benz technician or arrange to tow your
vehicle to the nearest Mercedes-Benz Center. For
services such as labor and/or towing charges may apply.
Refer to the Roadside Assistance manual for more
information. These programs are only available in the USA:
• Sign and Drive services: Services such as jump start,
a few gallons of fuel or the replacement of a f lat tire
with the vehicle spare tire are obtainable,
• Remote Vehicle Diagnostics: This function permits
the Mercedes-Benz Roadside Assistance dispatcher
to download malfunction codes and actual vehicle
data.
Notes:
The indicator lamp in the Roadside Assistance
button • remains illuminated in red for
approximately 10 seconds during the system self-check
after turning key in steering lock to position 2 (together
with the “SOS” button and the Information
button ¡).
See system self-check on page 148 when the indicator
lamp does not light up in red or stay on longer than
approximately 10 seconds.

If the BAS / ESP malfunction indicator lamp ¿ comes
on continuously with the engine running, a malfunction
has been detected in either system. Only partial engine
output will be available.
If the BAS malfunctions, the brake system functions in
the usual manner, but without BAS.
If the BAS / ESP malfunction indicator lamp stays
illuminated, have the BAS or ESP checked at your
authorized Mercedes-Benz Light Truck Center as soon
as possible.
With the ABS malfunctioning, the ESP is also switched
off.
Driving the vehicle with varied size tires will cause the
wheels to rotate at different speeds, therefore the ESP
may activate (yellow ESP warning lamp v in
speedometer dial comes on). For this reason, all wheels,
including the spare wheel, must have the same tire
outside diameter. When testing the parking brake on a brake test
dynamometer, the engine must be shut off. Otherwise,
the ESP will immediately be engaged and will apply the
rear wheel brakes.
In winter operation, the maximum effectiveness of the
ESP is only achieved with Mercedes-Benz recommended
M+S rated radial-ply tires and / or snow chains.
Synchronizing ESP
If the power supply was interrupted (battery
disconnected or empty), the BAS / ESP malfunction
indicator lamp may be illuminated with the engine
running.
After driving off the BAS / ESP malfunction indicator
lamp should go out after approximately 110 - 220 yd
(100 - 200 m).

Wheels
Replace rims or tires with the same designation,
manufacturer and type as shown on the original part.
See your authorized Mercedes-Benz Light Truck Center
for further information.
See your authorized Mercedes-Benz Light Truck Center
for information on tested and recommended rims and
tires for summer and winter operation. They can also
offer advice concerning tire service and purchase. Tire replacement
Front and rear tires should be replaced in sets.
Furthermore – in the event of tire replacement – the
optional regular size spare wheel should be used on the
rear axle. Rims and tires must be of the correct size and
type. For dimensions, see technical data on page 288.
We recommend that you break in new tires for
approximately 60 miles (100 km) at moderate speed.
It is imperative that the wheel mounting bolts be
fastened to a tightening torq ue of 110 ft.lb. (150 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to technical data on
page 288.
Wa r n i n g !
Do not mix different tire construction types (i.e.
radial, bias, bias-belted) on your vehicle because
handling may be adversely affected and may result
in loss of control.
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread
is badly worn, or if the tires have sustained
damage, replace them.When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result in
the bolts loosening and possibly an accident.
