Problems while driving
The engine runs erratically and misfires

An ignition cable may be damaged.

The engine electronics may not be
operating properly.

Unburned gasoline may have entered
the catalytic converter and damaged it.
Give very little gas.
Have the problem repaired by an
authorized 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 as soon as possible in
a safe location and turn off the engine.
Allow engine and coolant to cool off.
Check the coolant level and add
coolant if necessary (
page 255).In case of accident
If the vehicle is leaking gasoline:
Do not start the engine under any
circumstances.
Notify local fire and/or police
authorities.
If the extent of the damage cannot be
determined:
Contact 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.

Press buttonè orÿ repeatedly
until you see the standard display in
the multifunction display (

multifunction display.
Press and hold the reset button1
(
page 114) until the trip odometer is
reset.
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 which can occur
just by opening the hood. Stay away
f r o m t h e e n g i n e i f y o u s e e o r h e a r s t e a m
coming 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 the
coolant temperature warning lamp (
page 306)
and a warning in the multifunction display
(
page 335).
The engine should not be operated with the cool-
ant temperature above 248°F (120°C). Doing so
may cause serious engine damage which is not
covered by the Mercedes-Benz Limited
Warranty.
iDuring severe operating conditions, e.g.
stop-and-go traffic, the coolant temperature may
rise close to 248°F (120°C).

197 Controls in detail
Automatic climate control
Deactivating
It is possible to deactivate the cooling
function of the automatic climate control
system. The air in the vehicle will then no
longer be cooled or dehumidified.
Press ± button (page 188).
The indicator lamp on the ±
button comes on. The cooling function
switches off after a short delay.Activating
Moist air can fog up the windows. You can
dehumidify the air with the air
conditioning.
Press ± button again (page 188).
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.
iUnder certain circumstances, e.g. when the
fuel system is too hot and needs to be cooled,
the cooling switches on again automatically. The
red lamp on the ± button the automatic
climate control panel flashes.
After cooling the fuel system sufficiently, the air
conditioning switches off again and the red lamp
stops flashing.
!If you press the ± button on the auto-
matic climate control panel and it starts to flash,
this indicates that the air conditioning is losing
refrigerant. The compressor has turned 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 heating
depends on the coolant temperature and the
selected temperature. The blower will run at low
speed regardless of the air distribution control
setting.

245 Operation
Driving instructions
Emission control
Certain systems of the engine serve to
keep the toxic components of the exhaust
gases within permissible limits required by
law.
These systems, of course, will function
properly only when maintained strictly
according to factory specifications. Any
adjustments on the engine should,
therefore, be carried out only by qualified
Mercedes-Benz Center authorized techni-
cians. Engine adjustments should not be
altered in any way. Moreover, the specified
service jobs must be carried out regularly
according to Mercedes-Benz servicing
requirements. For details refer to the
Maintenance Booklet.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
unconsciousness 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
window fully open at all times.

248 Operation
At the gas station
Close the fuel filler flap until you hear
the latch close shut.
Check regularly and before a long trip
1Coolant
2Engine oil
3Brake fluidCoolant
For normal replenishing, use water (pota-
ble water quality). For more information,
see “Coolant” (
page 255) and see “Fu-
els, coolants, lubricants, etc.”
(
page 389).
Engine oil level
For more information on engine oil level,
see “Engine oil” (
page 253).
Brake fluid
iMake sure to close the fuel filler flap before
locking your vehicle as the flap locking pin pre-
vents closing after you have locked the vehicle.
iMore information on gasoline can be found
in the Factory Approved Service Products
pamphlet (USA only).
Leaving the engine running and the fuel cap open
can cause theú malfunction indicator lamp
(USA only) or the± malfunction indicator
lamp (Canada only) to illuminate.
For more information, see “Practical hints”
(
page 305).
iOpening the hood, see (page 250).
!If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum mark or
below, have the brake system checked for brake
pad thickness and leaks immediately. Notify an
authorized Mercedes-Benz Center immediately.
Do not add brake fluid as this will not solve the
problem. For more information, see “Practical
hints” (
page 303).
