55 Getting started
Driving
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
and turn off the engine. Allow engine
and coolant to cool.

Check the coolant level and add cool-
ant if necessary (
page 249).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.

114 Controls in detailInstrument clusterCoolant temperature gaugeDuring severe operating conditions, e.g.
stop-and-go traffic, the coolant tempera-
ture may rise close to 248°F (120°C).
The engine should not be operated with
the coolant temperature above 248°F
(120°C). Doing so may cause serious en-
gine damage which is not covered by the
Mercedes-Benz Limited Warranty.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 an 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 300) and a warning in the
multifunction display (
page 320).

190 Controls in detailAutomatic climate controlResidual 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

Press button T (
page 184).
The indicator lamp on button T
comes on.Deactivating

Press button T (
page 184).
The indicator lamp on button T
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 heat-
ing depends on the coolant tempera-
ture and the temperature set by the
operator. The blower will run at speed
setting1 regardless of the air distribu-
tion control setting.

239 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


Driving when your engine is badly
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.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.

249 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 compart-
ment.
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 380).
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 194°F (90°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.

Cleaning and care of the vehicle
If you have any questions about proper
care of your SLR, please contact an autho-
rized Mercedes-Benz Center.Depending on body color the characteris-
tic carbon structure of the body surface
may become visible due to high ambient
temperatures and humidity. This phenom-
enon is related to the technology and con-
cept of the vehicle’s body.
While in operation, even while parked, your
vehicle is subjected to varying external
influences which, if gone unchecked, can
attack the paintwork as well as the under-
body and cause lasting damage.
Such damage is caused not only by
extreme and varying climatic conditions,
but also by:


Air pollution


Road salt


Tar


Gravel and stone chipping
To avoid paint damage, you should
immediately remove:


Grease and oil


Fuel


Coolant


Brake fluid


Bird droppings


Insects


Tree resins, etc.
Frequent washing reduces and/or elimi-
nates the aggressiveness and potency of
the above adverse influences.
More frequent washings are necessary to
deal with unfavorable conditions:


near the ocean


in industrial areas (smoke, exhaust
emissions)


during winter operation
You should check your vehicle from time to
time for stone chipping or other damage.
Any damage should be repaired as soon as
possible to prevent corrosion.
Warning!
G
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the partic-
ular container. Always open your vehicle’s
doors or windows when cleaning the inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.iMercedes-Benz recommends that you
use Mercedes-Benz care products.
These have been specially developed
to suit Mercedes-Benz vehicles and are
state of the art. Mercedes-Benz care
products are available from any
Mercedes-Benz Center.

300 Practical hintsWhat to do if ...Problem
Possible cause
Suggested solution
D
The red coolant warning lamp
comes on when the engine is
running.
There is insufficient coolant in the reservoir.

Immediately add coolant to prevent
engine from overheating
(page 249).
If this warning lamp comes on frequently,
there is a leak in the cooling system.

Have the cooling system checked by
an authorized Mercedes-Benz Center.
If the coolant level is correct, the electric
radiator fan may be broken.

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 as soon as possible and allow
the engine and coolant to cool down.
