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
coolant if necessary (
page 327).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.

137 Controls in detail
Instrument cluster
Coolant temperature indicator
The coolant temperature indicator is on
the right side in the instrument cluster
(page 24).
During severe operating conditions, e.g.
stop-and-go traffic, the coolant tempera-
ture may rise close to 120°C.
The engine should not be operated with
the coolant temperature above 120°C.
Doing so may cause serious engine
damage which is not covered by the
Mercedes-Benz Limited Warranty.
Trip odometer
Make sure you are viewing the stan-
dard display in the multifunction dis-
play (
page 144).

If it is not displayed, press buttonè
orÿ on the multifunction steering
wheel repeatedly until the standard dis-
play appears (
page 140).

Press and hold the reset button on the
instrument cluster (
page 136) 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.
iExcessive coolant temperature triggers
a warning in the multifunction display
(page 398) and the red coolant warn-
ing lamp in the instrument cluster
comes on (
page 377).

207 Controls in detail
Automatic climate control (CLK 500/CLK 55 AMG)
Residual heat and ventilation* (Canada only)
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

Switch off the ignition (
page 36).

Press button9(
page 197).
The indicator lamp on the button
comes on.Deactivating

Press button9(
page 197).
The indicator lamp on the button goes
out.
The residual heat is automatically turned
off:


when the ignition is switched on


after about 30 minutes


if the battery voltage drops
iHow long the system will provide
heating depends on

the coolant temperature


the temperature set by the operator
The blower will run at speed setting 1
regardless of the air distribution
control setting.

317 Operation
Driving instructions
Coolant temperature
During severe operating conditions and
stop-and-go city traffic, the coolant
temperature 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
engine 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 lead to 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.

327 Operation
Engine compartment
Coolant
The engine coolant is a mixture of water
and anticorrosion/antifreeze. To check
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
compartment.
1Coolant expansion tank
2Cap

Using a rag, turn cap2 slowly
approximately one half turn to the left
to release any excess pressure.

Continue turning the cap2 to the left
and remove it.
The coolant level is correct if the level


for cold coolant: reaches the marking
(plastic bridge) inside the reservoir


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

Add coolant as required.

Replace and tighten cap2.
More information on coolant can be found
in the “Technical data” section
(
page 484).
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 the coolant temperature is
above 158°F (70°C). Allow the coolant
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.
