268 OperationTires and wheelsWarning!
G
When the tire inflation pressure monitoring
system warning light is lit, one or more of
your tires is significantly under-inflated. You
should stop in a safe location and check
your tires as soon as possible, and inflate
them to the proper tire inflation pressure as
indicated on the vehicle’s tire information
placard. Driving on a significantly under-in-
flated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Each tire, including the
spare, should be checked monthly when
cold and set to the recommended tire infla-
tion pressure as specified in the vehicle
placard and owner’s manual.
iThe recommended tire inflation pres-
sures for your vehicle can be found on
the tire placard located on the driver’s
door B-pillar. The tire inflation pres-
sures are not listed in the owner’s
manual.Warning!
G
The tire inflation pressure monitor does not
indicate a warning for wrongly selected tire
inflation pressures. Always adjust tire infla-
tion pressure according to the placard on
the driver’s door B-pillar or, if available, the
inside of the fuel filler flap.
The tire inflation pressure monitor is not
able to issue a warning due to a sudden dra-
matic loss of tire inflation pressure (e.g. tire
blowout caused by a foreign object). In this
case bring the vehicle to a halt by carefully
applying the brakes and avoiding abrupt
steering maneuvers.
iOperating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the tire inflation pressure
monitor to malfunction.Warning!
G
Follow recommend tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being over-
heated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.

<
The red Airbrake warning
lamp comes on while driving
and you hear a warning
sound.
The Airbrake or the central locking system
is malfunctioning.
Notify an authorized Mercedes-Benz Center
immediately.
>
The red gearshift indicator
lamp comes on while you are
driving.
You are driving with the manual shift pro-
gram. The engine is in the overrevving
range.
Shift to the next higher gear. Otherwise the
fuel supply will be interrupted to prevent the
engine from overrevving.
A
The yellow reserve fuel warn-
ing lamp lights up while you
are driving.
The fuel level has fallen into the reserve
range.
Refuel at the nearest gas station
(page 241).
=
The engine oil temperature
indicator comes on in the
tachometer while you are
driving.
The engine oil has not yet reached its
operating temperature.
Warm up the engine and do not drive at full
power until the operating temperature has
been reached.
The symbol will go out as soon as the engine
oil has reached its operating temperature.

H
The yellow warning lamp for the
tire pressure monitoring system
comes on.
The tire pressure monitoring system detects
a loss of pressure in at least one tire.
Bring the vehicle to a halt, avoiding
abrupt steering and braking maneu-
vers. Observe the traffic situation
around you.
Read and observe messages in the
multifunction display.
The warning lamp goes out once the tire
inflation pressure monitor has been reac-
tivated after the tire inflation pressure
has been corrected.
Warning!
G
When the tire pressure monitoring system
warning light is lit, one or more of your tires
is significantly under-inflated. You should
stop in a safe location and check your tires
as soon as possible, and inflate them to the
proper pressure as indicated on the vehi-
cle’s tire information placard. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Each tire,
including the spare, should be checked
monthly when cold and set to the recom-
mended inflation pressure as specified in
the vehicle placard and owner’s manual.
iThe recommended tire inflation pres-
sures for your vehicle can be found on
the tire placard on the driver’s door
B-pillar, not in the owner’s manual.

Unscrew the valve cap from tire
valve7.
Screw filler hosea onto tire valve7.
Insert electrical plug4 into vehicle
cigarette lighter socket.
Turn the SmartKey in the starter switch
to position1 (
page 40).
PressI on electric air pump switch8.
The electric air pump should now
switch on and inflate the tire.After 5 minutes, the pressure gauge must
display at least 26 psi (1.8 bar). The air
hose can become hot during inflation.
Please exercise appropriate caution.
If this tire inflation pressure is not at-
tained, turn off the electric air pump,
detach the filler hose from the tire
valve, and drive vehicle back and forth
very slowly approximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.
Unscrew the air pump’s air hose5
from flange6 of the TIREFIT
container.
Screw air hose5onto tire valve7.
Inflate the tire again.
Warning!
G
Observe safety instructions on air pump
label.
!Do not operate the electric air pump
longer than 8 minutes without interrup-
tion. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.

Brake fluid
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere.
Only brake fluid approved by
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
Premium unleaded gasoline
Warning!
G
Under extremely strenuous operating condi-
tions, this moisture content can lead to the
formation of bubbles in the system, thus re-
ducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s Mainte-
nance Booklet for replacement interval.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
injury. Whenever you are around gasoline,
avoid inhaling fumes and skin contact, extin-
guish all smoking materials. Never allow
sparks, flame or smoking materials near
gasoline!
!To maintain the engine’s durability and
performance, premium unleaded gaso-
line must be used. If premium unleaded
is not available and low octane fuel is
used, follow these precautions:
have the fuel tank only partially
filled with unleaded regular and fill
up with premium unleaded as soon
as possible
avoid full throttle driving and abrupt
acceleration
do not exceed an engine speed of
3000 rpm if the vehicle is loaded
with a light load such as two per-
sons and no luggage
do not exceed
2/3 of maximum ac-
celerator pedal position if the vehi-
cle is fully loaded or operating in
mountainous terrain
