556 Practical hintsWhat to do if …?Problem
Possible cause/consequence
Suggested solution
59The front passenger front
air bag off indicator lamp
does not illuminate and/or
does not remain illuminat-
ed with the weight of a typ-
ical 12-month-old child in a
standard child restraint or
less on the front passen-
ger seat.
The system is malfunctioning.

Make sure there is nothing between seat cushion and child seat and
check installation of the child seat.

Make sure no objects applying supplemental weight onto the seat
are present.

Make sure no objects which apply forces to the seat are present
(e.g. objects such as books, briefcases etc. lodged behind or around
the seat, head restraints pushing against roof etc.). The system may
recognize such forces as supplemental weight.

If the front passenger front air bag off indicator lamp remains out,
have the system checked as soon as possible by an authorized
Mercedes-Benz Center. Do not transport a child on the front pas-
senger seat until the system has been repaired.

Also read and observe any messages in the multifunction display
and follow corrective steps (
page 564).
Warning!

Rims and tires
Rims 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 provide best possible performance in conjunc-
tion with the driving safety systems on your vehi-
cle such as ABS or ESP
®. Tires specially
developed for your vehicle and tested and ap-
proved by Mercedes-Benz can be identified by
finding the following on the tire’s sidewall:


MO = M
ercedes-Benz O
riginal equipment
tires
Using tires other than those approved by
Mercedes-Benz may result in damage that is not
covered by the Mercedes-Benz Limited
Warranty.
!
Using tires other than those approved by
Mercedes-Benz can have detrimental effects,
such as


poor handling characteristics


increased noise


increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit dimen-
sional variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle parts. Damage to the tires or the vehicle may be the re-
sult.
i
Further information on tires and rims is
available at any authorized Mercedes-Benz
Center. A placard with the recommended tire in-
flation pressures is located on the driver’s door
B-pillar (
page 503). Some vehicles may have
supplemental tire inflation pressure information
for driving at high speeds (
page 510) or for ve-
hicle loads less than the maximum loaded
vehicle condition (
page 518). If such informa-
tion is provided, it can be found on the placard lo-
cated 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 maintenance
recommendation included with vehicle.
i
The following pages also list the approved
wheel rim and tire sizes for equipping your vehi-
cles with winter tires. Winter tires are not avail-
able as standard or optional factory equipment,
but can be purchased from an authorized
Mercedes-Benz Center.
Depending on vehicle model and the standard or
optional factory-equipped wheel rim/tire config-
uration on your vehicle (Appearance Package,
Sport Package etc.), equipping your vehicle with
winter tires approved for your vehicle model may
also require the purchase of two or four wheel
rims of the recommended size for use with these
winter tires. See an authorized Mercedes-Benz
Center for more information.
