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 gauge 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.

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.

Trip odometer
Make sure you are viewing the trip
odometer display (
page 139).

If it is not displayed, press the j or
k button on the multifunction
steering wheel repeatedly until the trip
odometer appears.

Press and hold reset button1
(page 136) 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
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.
!
Excessive coolant temperature triggers the
coolant temperature warning lamp (
page 337)
and a warning in the multifunction display
(
page 371).
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).

194 Controls in detailAutomatic climate controlActivating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.
Press button 2 once more
(page 185).
The indicator lamp on the button
comes on.
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
With the SmartKey:

Turn the SmartKey in the starter switch
to position1 or0, or remove it from
the starter switch.

Press button T (
page 185).
The indicator lamp on the button
comes on.
With KEYLESS-GO*:

Turn off the engine by pressing the
KEYLESS-GO* start/stop button and
open the driver’s door (with the driver’s
door open, the starter switch is in posi-
tion 0, same as with the SmartKey re-
moved from the starter switch)

Press button T (
page 185).
The indicator lamp on the button
comes on.
!
If the 2 button on the automatic climate
control panel 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.
i
How long the system will provide heating de-
pends on the coolant temperature and the se-
lected temperature. The blower will run at low
speed regardless of the air distribution control
setting.

270 OperationDriving instructions
Coolant temperature
During severe operating conditions, e.g.
stop-and-go city traffic, the coolant tem-
perature may rise close to approx. 266°F
(130°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 engine 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.

280 OperationEngine compartmentCoolantThe 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 compart-
ment.
1Coolant expansion tank

Using a rag, slowly turn the cap 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: is up to the upper
mark on the bracing rib of the coolant
expansion tank (translucent)


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

Add coolant as required.

Replace and tighten cap.
For more information, see “Coolants”
(
page 449).
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.
!
SL 600 and SL 65 AMG: Only open the cap
on coolant expansion tank1. Never open the
cap between the two charge-air coolers. Other-
wise, the engine could be damaged.

(USA only)
±
(Canada only)
The yellow engine malfunction
indicator lamp comes on while
driving.
Your fuel tank is empty.

After refueling, start, turn off, and re-
start the engine three or four times in
succession.
The limp-home mode is canceled. You
do not need to have your vehicle
checked.
D
The red coolant warning lamp
comes on when the engine is
running.
There is insufficient coolant in the reservoir.
If this warning lamp comes on frequently,
there is a leak in the cooling system.
If the coolant level is correct, the electric ra-
diator fan may be broken.

Immediately add coolant to prevent
engine from overheating
(page 280).

Have the cooling system checked.

If the coolant temperature is below
248 °F (120 °C), you can continue
driving to the nearest authorized
Mercedes-Benz Center.

Avoid high engine loads (e.g. driving
uphill) and stop-and-go driving.
D
The red coolant warning lamp
comes on while driving and you
hear a warning sound.
The coolant temperature has exceeded
248 °F (120 °C).

Stop in a safe location as soon as pos-
sible and allow the engine and coolant
to cool down.
