56 Getting startedDrivingProblems while driving
The engine runs erratically and misfires

An ignition cable may be damaged.


The engine electronics may not be op-
erating properly.


Unburned gasoline may have entered
the catalytic converter and damaged it.

Give very little gas.

Have the problem repaired by an au-
thorized Mercedes-Benz Center as
soon as possible.The coolant temperature is above
248°F (120°C)
The coolant is too hot and is no longer
cooling the engine.

Stop the vehicle in a safe location as
soon as possible and turn off the en-
gine. Allow engine and coolant to cool.

Check the coolant level and add cool-
ant if necessary (
page 280).In case of accident
If the vehicle is leaking gasoline:

Do not start the engine under any cir-
cumstances.

Notify local fire and/or police authori-
ties.
If the extent of the damage cannot be de-
termined:

Notify an authorized Mercedes-Benz
Center.
If no damage can be determined on the


major assemblies


fuel system


engine mount:

Start the engine in the usual manner.
iExcessive coolant temperature triggers
a warning message in the multifunction
display (
page 348).

135 Controls in detail
Instrument cluster
Coolant temperature gauge
During severe operating conditions,
e.g. stop-and-go traffic, the coolant tem-
perature may rise close to 248°F (120°C),
i.e. close to the red zone of the coolant
temperature gauge.
The engine should not be operated with
the coolant temperature above 248°F
(120°C), i.e. in the red zone of the coolant
temperature gauge. Doing so may cause
serious engine damage which is not cov-
ered by the Mercedes-Benz Limited
Warranty.
Trip odometer
Make sure you are viewing the trip
odometer display.

If it is not displayed, press the è or
ÿ button on the multifunction
steering wheel repeatedly until the trip
odometer appears (
page 137).

Press and hold reset buttonJ in the
instrument cluster (
page 134) until
the trip odometer is reset.
Warning!
G


Driving when your engine is badly over-
heated can cause some fluids which
may have leaked into the engine com-
partment to catch fire. You could be se-
riously burned.


Steam from an overheated engine can
cause serious burns and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.

(page 348).

194 Controls in detailAutomatic climate controlActivating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.
Press± again (
page 185).
The indicator lamp on the button±
goes out.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
Residual heat and ventilation
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.
Activating
Turn the SmartKey in the starter switch
to position1 or0, or remove it from
the starter switch.

Press buttonT (
page 185).
The indicator lamp on buttonT
comes on.Deactivating

Press buttonT (
page 185).
The indicator lamp on buttonT
goes out.
The residual heat is automatically turned
off:


when the ignition is switched on


after about 30 minutes


if the battery voltage drops
!If button± on the automatic cli-
mate control panel starts to flash, this
indicates that the air conditioning is
losing refrigerant. The compressor has
turned itself off. The air conditioning
cannot be turned on again.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.
iHow long the system will provide heat-
ing depends on the coolant tempera-
ture and the temperature set by the
operator. The blower will run at speed
setting 1 regardless of the air distribu-
tion control setting.

269 Operation
Driving instructions
Coolant temperature
During severe operating conditions,
e.g. stop-and-go traffic, the coolant tem-
perature may rise close to approx. 248°F
(120°C).
The engine should not be operated with
the coolant temperature over 248°F
(120°C). Doing so may cause serious en-
gine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and possible death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive with at least one window
fully open at all times.

partment, to catch fire. You could be se-

280 OperationEngine compartmentCoolant level
The engine coolant is a mixture of water
and anticorrosion/antifreeze.
When checking the coolant level,

the vehicle must be parked on level
ground, and


the engine must be cool.
The coolant expansion tank is located on
the passenger side of the engine compart-
ment.
1Coolant expansion tank

Using a rag, turn the cap slowly approx-
imately one half turn to the left to re-
lease any excess pressure.

Continue turning the cap to the left and
remove it.
The coolant level is correct if the level


for cold coolant: reaches the white
marking (plastic bridge) inside the cool-
ant expansion tank.


for warm coolant: is approximately
0.6 in (1.5 cm) higher

Add coolant as required.

Replace and tighten cap.
For more information on coolant, see
“Coolants” (
page 422).
Warning!
G
In order to avoid any possibly serious burns:

Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system,
or if the coolant temperature gauge indi-
cates that the coolant is overheated.


Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 158°F (70°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid and
is under pressure.


Using a rag, slowly open the cap approx-
imately
1/2 turn to relieve excess pres-
sure. If opened immediately, scalding
hot fluid and steam will be blown out un-
der pressure.


Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene gly-
col which may burn if it comes into con-
tact with hot engine parts.
!CL 600 and CL 65 AMG:
Only open the cap on coolant expan-
sion tank1. Never open the cap be-
tween the charge-air coolers.
Otherwise, the engine could be dam-
aged.
