Notes:
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 and the yellow ESP warning
lampv in the speedometer dial come on with the
electronic key in steering lock position 2. They should
go out with the engine running.
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 ESP warning message is displayed, have the BAS
or ESP checked at your authorized Mercedes-Benz
Center as soon as possible.
For ESP warning message, see page 244.
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 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.
Turn steering wheel completely to the left and then to
the right. The BAS/ESP malfunction indicator lamp
should go out.

repaired immediately.
It may indicate that the poly-V-belt has broken. Should
this condition occur, the poly-V-belt must be replaced
before continuing to operate the vehicle. Otherwise, the
engine will overheat due to an inoperative water pump
which may result in damage to the engine.
Do not continue to drive the vehicle with this message
displayed.
Doing so could result in serious engine damage that is
not covered by the Mercedes-Benz Limited Warranty.

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 trunk
under the trunk floor.
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
cloth ing. In c ase it does, im mediately f lush 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..

269 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
electronic key is in steering lock position 0. The battery
and its filler caps 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 would be
damaged.Note:
After reconnecting the battery also set the clock (see
page 108), resynchronize the front seats (see page 49),
front seat head restraints (see page 49), the express
feature of the power windows (see page 148), the
sliding/pop-up roof (see page 150) and the electronic
stability program (ESP) (see page 220).
Battery recycling
Batteries contain material 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.

270 Jump starting
Te ch n ica l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index
Jump startingImportant!
A discharged battery can freeze at approx. +14°F
(–10°C). In that case, it must be thawed out before
jumper cables are used. Attempting to jump start a
frozen battery can result in it exploding, causing
personal injury.
Jumper cable specifications:
•Minimum cable cross-section of 25 mm
2 or approx.
2AWG
•Maximum length of 11.5 ft. (3.5 m).
If th e battery is discha rged, th e eng ine shoul d be started
with jumper cables and the (12 V) battery of another
vehicle.
Only use 12 V battery to jump start your vehicle. Jump
starting with more powerful battery could damage the
vehicle’s electrical systems, which will not be covered
by the Mercedes-Benz Limited Warranty.
The battery is located in the trunk under the trunk f loor.
Wa r n i n g !
Failure to follow these directions will cause
damage to the electronic components, and can lead
to a battery explosion and severe injury or death.Never lean over batteri es wh ile connec ting or jump

this fluid to come in contact with eyes, skin or

area with water, and seek medical help if
necessary.A battery will also produce hydrogen gas, which is
flammable and very explosive. Keep flames or
sparks away from battery, avoid improper
connection of jumper cables, smoking etc..Read all instructions before proceeding.

271 Jump starting
Te ch n ica l
data Instruments
and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index Proceed as follows:
1. Position the vehicle with the charged battery so that
the jumper cables will reach, but never let the
vehicles touch. Make sure the jumper cables do not
have loose or missing insulation.
2. On both vehicles:
•Turn off engine and all lights and accessories,
except hazard warning f lashers or work lights.
•Apply parking brake and shift selector lever to
position “P”.
Important!
3. Clamp one end of the first jumper cable to the
positive (+) under hood terminal of the discharged
battery and the other end to the positive (+) terminal
of the charged battery. Make sure the cable clamps
do not touch any other metal parts.
4. Clamp one end of the second jumper cable to the
grounded negative (–) terminal of the charged
battery and the final connection to the negative (–)
terminal (2) of the discharged battery.Important!
5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached.
Notes:
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel may damage the catalytic
converter.
