Possible cause
Suggested solution
Ï
Coolant
Stop, engine off!
The coolant is too hot.
The poly-V-belt could be broken.

Stop the vehicle.

Only start the engine again after the mes-
sage disappears. You could otherwise dam-
age the engine.

Stop immediately and check the
poly-V-belt.
If it is broken, do not drive any further.
Notify an authorized Mercedes-Benz
Center.
If it is in order, drive immediately to the
nearest authorized Mercedes-Benz Cen-
ter.
Warning!
G
Driving when your engine is badly overheat-
ed can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously burned.
Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until it
cools down. The engine should not be oper-
ated with the coolant temperature above
266°F (130°C). Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.

344 Practical hintsBatteries
Disconnecting the battery
Depress the parking brake firmly or
move the gear selector lever to
positionP.

Open the trunk (
page 261).

Disconnect battery negative lead1.

Remove cover2 from the positive ter-
minal.

Disconnect the battery positive lead.
Removing the battery
Remove the screw-nuts securing the
battery.

Remove the battery bracket.

Take out the battery.
Charging and reinstalling the battery
Charge battery in accordance with the
instructions of the battery charger
manufacturer.

Reinstall the charged battery. Follow
the previously described steps in re-
verse order.
!Never loosen or detach battery termi-
nal clamps while the engine is running
or the key is in the starter switch. Oth-
erwise the alternator and other elec-
tronic components could be severely
damaged.
Have the battery checked regularly by
an authorized Mercedes-Benz Center.
Contact your authorized
Mercedes-Benz Center for further infor-
mation.Warning!
G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof battery only to avoid the risk
of acid burns in the event of an accident.
Warning!
G
With a disconnected battery

the brake boosting effect is not avail-
able.
You need more power to brake and
brake pedal travel is increased. If neces-
sary, you must depress the brake pedal
with full power.


you can no longer turn the ignition key
or, in cars with KEYLESS-GO*, pressing
the KEY-LESS-GO button* on the gear
selector lever has no effect.

346 Practical hintsJump starting
Jump starting
If the battery is discharged, the engine can
be started with jumper cables and the bat-
tery of another vehicle. Observe the follow-
ing:

Jump starting should only be performed
when the engine and catalytic convert-
er are cold.


Do not start the engine if the battery is
frozen. Let the battery thaw out first.


Only jump start from batteries with the
same voltage rating.


Use only jumper cables with sufficient
cross-section, insulated terminal
clamps and polarity reversal protec-
tion.
Warning!
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 batteries while connecting
or jump starting, 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 very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking etc.
Read all instructions before proceeding.
iJumper cables with polarity reversal
protection are available at any autho-
rized Mercedes-Benz Center.
!Jump starting may only be performed
on the main battery installed in the
trunk.
Avoid repeated and lengthy starting at-
tempts.
Do not attempt to start the engine us-
ing a battery quick charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter.
Make sure the jumper cables do not
have loose or missing insulation.
Make sure the cable clamps do not
touch any other metal part while the
other end is still attached to a battery.

347 Practical hints
Jump starting
The battery is located in the trunk on the
right hand side underneath the luggage
box (
page 325). Only jump start the ve-
hicle from the battery in the trunk.

Make sure that the two vehicles do not
touch.

Turn off all electrical consumers.

Apply parking brake.

Shift selector lever to positionP.1Positive terminal of charged battery
2Positive terminal of discharged battery
3Vehicle ground
4Negative terminal of charged battery

Connect positive terminals1 and2 of
the batteries with the jumper cables.
Clamp cable to charged battery1 first.

Start engine of the vehicle with the
charged battery and run at idle speed.

Connect negative terminal4 of the
charged battery and vehicle ground3
(lock ring of the trunk lid lock) in the
trunk with the jumper cable. Clamp ca-
ble to charged battery4 first.

Start the engine of the disabled vehi-
cle.
Now you can again turn on the electrical
consumers. Do not turn on the lights under
any circumstances.

Remove the jumper cables first from
vehicle ground3 and negative
terminal4 and then from positive
terminals1 and2.

Have the battery checked at the next
authorized Mercedes-Benz Center.
Warning!
G
Keep flames or sparks away from battery.
Do not smoke.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 266).
iThe message
Malfunction - electric
consumers switched off
may appear
in the instrument cluster. It will disap-
pear as soon as the battery is suffi-
ciently charged.
!Vehicles with automatic transmission:
Do not tow-start the vehicle.

371 Technical data
Fuels, coolants, lubricants etc.
If the coolant level is low, water and MB
Anticorrosion /Antifreeze should be used
to bring it up to the proper level (have cool-
ing system checked for signs of leakage).
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult your authorized Mercedes-Benz
Center.Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifical-
ly formulated to protect the aluminum
parts. (Failure to use such anticorro-
sion/antifreeze coolant will result in a sig-
nificantly shortened service life.)Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz 325.0 Anticorrosion/Anti-
freeze Agent.
Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to your authorized Mercedes-Benz
Center for service.
