51 Getting started
Driving
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 is over 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 292).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.

adjustable booster blower
2Left center air vent
3Right center air vent
To open center air vents and to adjust the 
booster blower:
Turn thumbwheel1.
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 
distribution control setting.
iThe booster blower allows airflow 
speed to the rear passenger compart-
ment to be increased at four different 
levels.
The temperature at the air vents for 
rear passenger compartment2 
and3 is the same as at the dashboard 
center air vents.

!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. Noti-
fy an authorized Mercedes-Benz Center 
immediately. Do not add brake fluid as 
this will not solve the problem. For 
more information, see also “Practical 
hints” (
page 313).

292 OperationEngine compartmentCoolant
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.
1Coolant expansion tank
Using a rag, turn the cap slowly approx-
imately one half turn to the left to re-
lease any excess pressure.
Continue turning the cap to the left and 
remove it.
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 engine 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 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.

293 Operation
Engine compartment
The coolant level is correct if the level
for cold coolant: reaches the black top 
part of the reservoir
for warm coolant: is approx. 0.6 in 
(1.5 cm) higher
Add coolant as required.
Replace and tighten cap.
More information on coolant can be found 
in the “Technical data” section 
(
page 414).

315 Practical hints
What to do if …?
Problem
Possible cause
Suggested solution
•
The red coolant warning lamp 
comes on when the engine is 
running.
There is insufficient coolant in the reservoir.
Add coolant to prevent engine from 
overheating (
page 292).
If this warning lamp comes on frequently, 
there is a leak in the cooling system.
Have the cooling system checked.
If the coolant level is correct, the electric ra-
diator fan may be broken.
If the coolant temperature is below 
257 °F (125 °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.
•
The red coolant warning lamp 
comes on while driving and you 
hear a warning sound.
The coolant temperature has exceeded 
257 °F (125 °C).
Stop as soon as possible and allow 
the engine and coolant to cool down.
Warning!
G
Driving when your engine is badly overheat-
ed 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 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.

Coolant
Check level
The coolant level is too low.
Add coolant (
page 292).
If you have to add coolant frequently, 
have the cooling system checked by 
an authorized Mercedes-Benz Center.
Warning!
G
Do not spill antifreeze on hot engine parts. 
Antifreeze contains ethylene glycol which 
may burn if it comes into contact with hot 
engine parts. You can be seriously burned.
!Do not ignore the low engine coolant 
level warning. Extended driving with 
the message and symbol displayed 
may cause serious engine damage not 
covered by the Mercedes-Benz Limited 
Warranty.
Do not drive without sufficient amount 
of coolant in the cooling system. The 
engine will overheat, causing major en-
gine damage.
