cluster displayPractical hints Car care Index Fuel reserve and fuel cap placement warning
With the key in steering lock position 2, the fuel reserve
warning lamp comes on. It should go out immediately
when the engine is running.
If the warning lamp does not go out after starting the
engine, or if it comes on while driving, it indicates that
the fuel level is down to the reserve quantity of
approximately 2.1 gal (8 liters).
The warning lamp blinks when the fuel cap is not
closed, or a fuel system leak has been detected.
Retighten cap and see if warning lamp goes out after
restart and next OBD selfcheck.
If the warning lamp continues to blink after closing the
fuel cap correctly, have the fuel system checked at your
authorized Mercedes-Benz Center as soon as possible.
Leaving the engine running and the fuel cap open can
a lso c ause t he “CH ECK ENG INE” lamp to ill uminate, see
also page 178.Electronic stability program (ESP) — warning lamp
The yellow ESP warning lamp in the
speedometer dial comes on with the key in
steering lock position 2. It should go out
with engine running.
See page 170 if the warning lamp lights up or f lashes
when the vehicle is moving.
BAS / ESP malfunction indicator lamp
The malfunction indicator lamp for the ESP
is combined with that of the BAS.
The yellow BAS / ESP malfunction indicator
lamp in the instrument cluster comes on with the key in
steering lock position 2. It shoul d go out w it h th e engine
running.
If the BAS / ESP malfunction indicator lamp comes on
continuously with the engine running, see page 166
and 170.

ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the
instrument cluster comes on with the key in
steering lock position 2 and should go out
with the engine running.
When the ABS malfunction indicator lamp symbol and
warning in the instrument cluster come on while the
engine is running, it indicates that the ABS has detected
a malfunction and has switched off. In this case, the
brake system functions in the usual manner, but
without antilock assistance.
With the ABS malfunctioning, the BAS and ESP are also
switched off. Both malfunction indicator lamps come on
with the engine running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
Have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
See page 168 for notes on antilock brake system (ABS).Telescoping steering column warning lamp
With the key in steering lock position 2, the
indicator lamp in the instrument cluster
comes on. It should go out when the engine
is running.
If the indicator lamp does not go out after starting the
engine, the adjustable steering column is not locked
properly.
Important!
Do not drive the vehicle until you have properly locked
the steering column.

The jack is designed exclusively for jacking up the
veh icle at th e jack tu bes bu ilt into eit her side of th e
vehicle. To help avoid personal injury, use the jack
only to lift the vehicle during a wheel change.
Never get beneath the vehicle while it is supported
by t he jack. Keep hands and feet away from th e area
under the lifted vehicle. Always firmly set parking
brake and block wheels before raising vehicle with
jack.Do not disengage parki ng brake wh ile th e vehi cle i s
raised. Be certain that the jack is always vertical
when in use, especially on hills. Always try to use
the jack on level surface. Be sure that the jack arm
is fully inserted in the jack tube. Always lower the
vehicle onto sufficient capacity jackstands before
working under the vehicle.

Changing wheelsMove vehicle to a level area which is a safe distance
from the roadway.
1.Set parking brake and turn on hazard warning
flasher.
2.Move selector lever to position “P” and turn off
engine (manual transmission to 1st or reverse gear).
3.Prevent vehicle from rolling away by blocking
wheels with wheel chocks (not supplied with
vehicle) or sizable wood block or stone. When
changing a wheel on a hill, place chocks on the
downhill side blocking both wheels of the other
axle. On a level road, place one chock in front of and
one behind the wheel that is diagonally opposite to
the wheel being changed.

209 Tires, wheels
Te ch n ica l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index Tire inflation pressure
A table (see fuel filler f lap) 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
+3psi (+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 at
intervals of no more than 14 days are therefore
essential.

211 Battery
Te ch n ica l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
key is in steering lock position 0. The battery must
always be securely installed when the vehicle is in
operation. During removal and installation always
protect the disconnected battery positive (+) terminal
with the cover attached to the battery.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components will be
damaged.Battery recycling
Batteries contain materials that can harm the
environment with improper disposal.
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.

216 Towing the vehicle
Te ch n ica l

and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index
Important!
When towing the vehicle, please, note the following:
With the automatic central locking activated and the
key in steering lock position 2, the vehicle doors lock if
the left front wheel as well as the right rear wheel are
turning at vehicle speeds of approximately 9 mph
(15 km / h) or more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking.Note:
To signal turns while being towed with hazard warning
f lash er in u se, turn key in steering l ock to position 2 a nd
activate combination switch for left or right turn signal
in usual manner – only the selected turn signal will
operate. Upon canceling the turn signal, the hazard
warning flasher will operate again.
Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (key in steering lock position 0
or 1). Otherwise, the ESP will immediately be engaged
and will apply the rear wheel brakes. Switch off the
tow-away alarm as well as the ESP, see page 37 and 170.
