Check for proper engagement before
driving.
Adjust to a comfortable seating position
that still allows you to reach the
accelerator / brake pedal safely. The posi-
tion should be as far rearward as possible,
consistent with ability to properly operate
controls.
Warning!
G
Children 12 years old and under must never
ride in this vehicle, except in a
Mercedes-Benz authorized BabySmart
TM1
compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger front air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates in a crash. If this happens, serious or
fatal injury will result.
Infants and small children must be seated in
an appropriate infant or child restraint sys-
tem, which is properly secured with the ve-
hicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.

tive Corp.

187 Operation
Tires and wheels
Tire pressure changes by approximately
1.5 psi (0.1 bar) per 18°F (10°C) of air
temperature change. Keep this in mind
when checking tire pressure where the
temperature is different from the outside
temperature.
The tire temperature and with it the tire
pressure is increased also while driving,
depending on the driving speed and the
tire load.Check the spare tire periodically for condi-
tion and inflation. Spare tires will age and
b e c o m e w o r n o v e r t i m e e v e n i f n e v e r u s e d ,
and thus should be inspected and replaced
when necessary.
Rotating wheels
The wheels can be rotated every 3 000 to
6 000 miles (5 000 to 10 000 km), or soon-
er if necessary, according to the degree of
tire wear. The same direction of tire rota-
tion must be retained.Rotate the wheels before the characteris-
tic tire wear pattern becomes visible
(shoulder wear on front wheels and tread
center wear on rear wheels).
Thoroughly clean the inner side of the
wheels after each rotation. Check and en-
sure proper tire inflation pressure.
Warning!
G
Follow recommended inflation pressure.
Do not overinflate tires. Overinflated tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.Warning!
G
Rotate front and rear wheels only if they are
of the same size.
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
80 lb-ft (110 Nm).
Use only genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.

240 Practical hintsFlat tire

Visit an authorized Mercedes-Benz
Center as soon as possible to obtain a
new TIREFIT container and/or filler
hose.

Bring used TIREFIT materials to an
authorized Mercedes-Benz Center for
proper disposal.

Replace your TIREFIT container every
four years. Containers are available at
your authorized Mercedes-Benz Cen-
ter.
Sealing tires with TIREFIT kit 2
Small tire punctures, only those in the
tread, can be sealed with TIREFIT.
TIREFIT can be used in ambient tempera-
tures down to -4°F (-20°C).
Warning!
G
Follow recommend tire pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the driver’s door latch
post). Overloading the tires can overheat
them, possibly causing a blowout.
Warning!
G
Keep TIREFIT away from sparks, open flame
or heat source.
Do not smoke.
Warning!
G
Take care not to allow the contents of
TIREFIT to come in contact with hair, eyes or
clothing. TIREFIT is harmful if inhaled, swal-
lowed or absorbed through the skin. It caus-
es skin, eye and respiratory irritation.
Any contact with eyes or skin should be
flushed immediately with plenty of water.
If clothing comes in contact with TIREFIT,
change clothing as soon as possible.
In case of allergic reaction or rash, consult a
physician immediately.Warning!
G
Keep TIREFIT out of reach of children.
If swallowed, rinse mouth immediately with
plenty of water and drink plenty of water.
Do not induce vomiting!
Consult a physician immediately.
Keep away from open flame or heat source.
