Problems 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
off.
Check the coolant level and add cool-
ant if necessary (
page 518).In case of accident
If the vehicle is leaking gasoline:
Do not start the engine under any cir-
cumstances.
Move away from vehicle.
Notify local fire and/or police authori-
ties.
If the extent of the damage cannot be de-
termined:
Contact an authorized Mercedes-Benz
Center or call Roadside Assistance.
If no damage can be determined on the

major assemblies

fuel system

engine mount:
Start the engine in the usual manner.
iTo signal minor directional changes such as
changing lanes, press combination switch only
to point of resistance and release. The corre-
sponding turn signals will flash three times.
iExcessive coolant temperatures trigger a
warning message in the multifunction display
(
page 580).

403 Controls in detail
Instrument cluster
Coolant temperature gauge
The coolant temperature gauge is on the
left side in the instrument cluster
(
page 30).
Tachometer
The red marking on the tachometer de-
notes excessive engine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Warning!G

Driving when your engine is overheated
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 hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle
until the engine has cooled down.
!Excessive coolant temperature triggers a
warning in the multifunction display
(
page 610).
The engine should not be operated with the cool-
ant 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 covered by the Mercedes-Benz Lim-
ited Warranty.
iDuring severe operating conditions,
e.g. stop-and-go traffic, the coolant temperature
may rise close to 248°F (120°C), i.e. close to
the red zone of the temperature gauge.
!Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited Warran-
ty.

Automatic climate control
Convenience opening: Press
button
, for approximately
2 seconds.
The side windows and/or tilt/sliding
sunroof will return to their previous po-
sition. You can release button
,
once the opening procedure has be-
gun. The windows and tilt/sliding sun-
roof continue opening until they have
reached their previous positions. The
indicator lamp on the button goes out.
The air recirculation mode is deactivat-
ed.
Residual engine heat and ventilation
With the engine switched off, it is possible
to continue to heat or ventilate the interior.
This feature makes use of the residual heat
produced by the engine.Activating
Switch off the ignition (page 336).
Press buttonT (page 453) up or
down.
The indicator lamp on the button
comes on.
Deactivating
Press buttonT (page 453) up or
down.
The indicator lamp on the button goes
out.
iIf you switch on the residual heat function
when outside temperatures are high, only the
ventilation will be switched on.
iRegardless of the selected air volume, the
blower operates at low speed when heating. In
case of ventilation the blower operates at higher
speed.
iHow long the system will provide heating de-
pends on

the coolant temperature

the temperature set by the operator
iThe residual heat is automatically turned off:

when the ignition is switched on

after approximately 30 minutes

if the battery voltage drops

if the coolant temperature is too low


508 Operation
Driving instructions
Coolant temperature
During severe operating conditions,
e.g. stop-and-go traffic, the coolant tem-
perature may rise close to approximately
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 (CO), and inhaling it can cause un-
consciousness 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 only with at least one win-
dow fully open at all times.
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.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle
until the engine has cooled down.

518 Operation
Engine compartment
Coolant 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

the coolant temperature must be
below 158°F (70°C)
The coolant expansion tank is located on
the passenger side of the engine compart-
ment.
Example illustration from CL 550
1Cap
2Coolant expansion tank
Using a rag, turn cap1 slowly approx-
imately one half turn counterclockwise
to release any excess pressure.
Continue turning the cap counterclock-
wise 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 cap1.
For more information on coolant, see the
“Technical data” section (
page 689).
Warning!G
In order to avoid potentially 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.
