128 Controls in detailInstrument clusterCoolant temperature gauge
The coolant temperature gauge is on the
left side in the instrument cluster
(page 24).During 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.
Trip odometer
Make sure you are viewing the trip
odometer and main odometer in the
multifunction display (
page 130).

I f i t i s n o t d i s p l a y e d , p r e s s b u t t o nè
orÿ on the multifunction steering
wheel (
page 131) until the trip
odometer appears in the multifunction
display.

Press and hold the reset button in the
instrument cluster (
page 127) until
the trip odometer is reset.
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.

301 Operation
Engine compartment
Coolant level
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
2Cap

Using a rag, turn cap2 slowly approx-
imately 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 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.
For more information on coolant, see
“Coolants” (
page 444).
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
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.

Possible cause/consequence
Possible solution
•
Coolant
Stop, engine off!
The poly-V-belt could be broken.

Stop the vehicle in a safe location and
immediately turn off the engine.

Check the poly-V-belt.
If it is broken:

Do not continue to drive. Otherwise the engine will
overheat due to an inoperative water pump which
may result in damage to the engine. Notify an au-
thorized Mercedes-Benz Center.
If it is intact:

Do not continue to drive the vehicle with this mes-
sage displayed. Doing so could result in serious
engine damage that is not covered by the
Mercedes-Benz Limited Warranty.

Observe the coolant temperature gauge in the in-
strument cluster (
page 24).

Drive immediately to the nearest authorized
Mercedes-Benz Center.
Coolant
Visit workshop.
The cooling fan for the coolant is
malfunctioning.

Observe the coolant temperature gauge in the in-
strument cluster (
page 24).

Have the fan replaced as soon as possible.

The displays and indicator/warning
lamps in the driver’s field of vision,
including the tachometer, speedo-
meter, engine temperature display and
fuel gauge.Kickdown
Depressing the accelerator past the
point of resistance shifts the transmis-
sion down to the lowest possible gear.
This very quickly accelerates the
vehicle and should not be used for
normal acceleration needs.
