282 OperationTires and wheelsThoroughly clean the mounting face of
wheels and brake disks, i.e. the inner side
of the wheels/tires, during each rotation.

Anti-theft wheel nuts
Your vehicle is equipped with anti-theft
wheel nuts that prevent the theft of your
vehicle’s wheels.
1Anti-theft wheel nut
2Wheel nut key
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
95 lb-ft (130 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.
Warning!
G
Pull the parking brake lever up as many
notches as possible and move the gear se-
lector lever to positionP, before loosening
the wheel bolts. Otherwise the vehicle may
move and cause an accident and/or serious
personal injury. !Do not use air tools, such as an impact
wrench, when installing or removing
the anti-theft wheel nuts. An impact
wrench can damage the anti-theft
wheel nuts and the wheel nut key, or
cause them to malfunction.
!Store wheel bolts and anti-theft wheel
nuts not currently in use in a safe place
to avoid damage to the threads.

comes on while driving
There is insufficient brake fluid in the
reservoir.
Risk of accident! Carefully stop the vehicle
and notify an authorized Mercedes-Benz
Center. Do not add brake fluid! This will not
solve the problem.
Warning!
G
Driving with the brake warning lamp illumi-
nated can result in an accident. Have your
brake system checked immediately if the
brake warning lamp stays on. Do not add
brake fluid before checking the brake sys-
tem.
Overfilling the brake fluid reservoir can re-
sult in spilling brake fluid on hot engine
parts and the brake fluid catching fire. You
can be seriously burned.
!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.

The yellow engine malfunc-
tion indicator lamp comes on
while driving.
There is a malfunction in:
The fuel injection system
The ignition system
The emission control system
Systems which effect emissions
Such malfunctions may result in excessive
emissions values and may switch the en-
gine to its limp-home (emergency opera-
tion) mode.
Have the vehicle checked as soon as possi-
ble by an authorized Mercedes-Benz Center.
An on-board diagnostic connector is used by
the service station to link the vehicle to the
shop diagnostics system. It allows the accu-
rate identification of system malfunctions
through the readout of diagnostic trouble
codes. It is located in the front left area of
the footwell next to the parking brake.
Your gas tank is empty.
After refuelling, start, turn off and restart the
engine three or four times in succession.
The limp-home mode is canceled. You do not
need to have your vehicle checked.
The fuel cap is not closed tightly.
Check the fuel cap.

lower gear to use the engine’s braking power
(page 170).
Cautiously continue driving so that the air
stream will cool down the brakes.
Release

TIREFIT can be used in ambient tempera-
tures down to -4°F (-20°C).
Foreign objects (e.g. screws or nails)
should not be removed from the tire.
Take TIREFIT, the sticker, and the elec-
tric air pump out of the trunk.
!A wheel change should only be carried
out at an authorized Mercedes-Benz
Center. Otherwise there is a danger of
damaging the vehicle by jacking it up
incorrectly.
iOpen door only when conditions are
safe to do so.Warning!
G
Keep TIREFIT away from sparks, open flame
or heat source.
Do not smoke.
Warning!
G
TIREFIT is a limited repair device. TIREFIT
cannot be used for cuts or punctures larger
than approximately 0.16 in (4 mm) and tire
damage caused by driving with extremely
low tire inflation pressure, or on a flat tire, or
a damaged wheel.
Do not drive the vehicle under such circum-
stances.
Contact your nearest Mercedes-Benz
Center for assistance or call Roadside
Assistance. !After using TIREFIT, the tire inflation
pressure sensor may have to be re-
placed.
