H
The yellow warning lamp for the
tire inflation pressure monitor
comes on.
The tire inflation pressure monitor detects a
loss of pressure in at least one tire.
Bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.
Observe the traffic situation around you.
Read and observe messages in the mul-
tifunction display.
The warning lamp goes out once the tire in-
flation pressure monitor has been reactivat-
ed after the tire inflation pressures have
been corrected.
Warning!
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 and check your tires as soon as
possible, and inflate them to the proper
pressure as indicated on the vehicle’s tire in-
formation placard. Driving on a significantly
under-inflated tire causes the tire to over-
heat 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 or, if available, the inside of the
fuel filler flap, not in the owner’s
manual.

TANK OPEN
CHECK FILLER CAP
A loss of pressure has been detected in
the fuel system. The fuel cap may not be
closed properly or the fuel system may be
leaky.
Check the fuel cap (
page 270).
If it is not closed properly:
Close the fuel cap.
If it is closed properly:
Have the fuel system checked by an au-
thorized Mercedes-Benz Center.

410 Technical dataRims and Tires
!
Only use tires which have been tested
and approved for your vehicle by
Mercedes-Benz. Tires approved by
Mercedes-Benz are developed to pro-
vide best possible performance in con-
junction with the driving safety
systems on your vehicle such as ABS or
ESP
®. Tires specially developed for
your vehicle and tested and approved
by Mercedes-Benz can be identified by
finding the following on the tire’s side-
wall:
MO = M
ercedes-Benz O
riginal
equipment tires
AMG vehicles:
Does not apply to all approved tires
on AMG vehicles. For information
on tested and approved tires for
AMG vehicles, contact an autho-
rized Mercedes-Benz Center.
Using tires other than those approved
by Mercedes-Benz may result in dam-
age that is not covered by the
Mercedes-Benz Limited Warranty.!Using tires other than those approved
by Mercedes-Benz can have detrimen-
tal effects, such as
poor handling characteristics
increased noise
increased fuel consumption
Moreover, tires and rims not approved
by Mercedes-Benz may, under load,
exhibit dimensional variations and dif-
ferent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle may be the result.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A placard with
the recommended tire inflation pres-
sures is located on the driver’s door
B-pillar (
page 286). Some vehicles
may have supplemental tire inflation
pressure information for driving at high
speeds (page 293) or for vehicle
loads less than the maximum loaded
vehicle condition (
page 299). If such
information is provided, it can be found
on the placard located on the inside of
the fuel filler flap. The tire inflation
pressure should be checked regularly
and should only be adjusted on cold
tires. Follow tire manufacturer’s main-
tenance recommendation included
with vehicle.
421 Technical data
Fuels, coolants, lubricants, etc.
Premium unleaded gasoline
Fuel requirements
Use only premium unleaded fuel:
The octane number (posted at the
pump) must be 91 min. It is an average
of both the Research (R) octane num-
ber and the Motor (M) octane number:
(R+M)/2). This is also known as the
ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates
such as ethanol, IPA, IBA and TBA can be
used provided the ratio of any one of these
oxygenates to gasoline does not exceed
10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is
not allowed. Gasohol, which contains
10% ethanol and 90% unleaded gasoline,
can be used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
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.
