54 Getting startedDrivingProblems 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 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.

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 310)
and a warning in the multifunction display
(
page 340).
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.
i
During severe operating conditions, e.g.
stop-and-go traffic, the coolant temperature may
rise close to 248°F (120°C).

195 Controls in detail
Automatic climate control
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 button T (
page 186).
The indicator lamp on button comes
on.Deactivating

Press button T (
page 186).
The indicator lamp on 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


if the coolant temperature is too low
i
How 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.

246 OperationDriving 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
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.
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
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 the
engine has cooled down.

255 Operation
Engine compartment
Coolant
The engine coolant is a mixture of water
and anticorrosion/antifreeze.
When checking coolant level,

the vehicle must be parked on level
ground


the coolant temperature must be be-
low 158°F (70°C)
1Expansion tank

Using a rag, turn cap slowly approxi-
mately one half turn to the left to
release 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 upper
mark on the bracing rib of the ex-
pansion tank (arrow)


for warm coolant: is approximately
0.4 in (1 cm) higher

Add coolant as required.

Replace and tighten cap.
For more information, see “Coolants”
(
page 398).
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
approximately
1/2 turn to relieve excess
pressure. If opened immediately, scald-
ing hot fluid and steam will be blown out
under pressure.


Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene
glycol which may burn if it comes into
contact with hot engine parts.
