pressure
There was a tire inflation pressure warning
message.
The yellow warning lamp for the tire pres-
sure monitoring system comes on and you
have not reactivated the system since the
last tire inflation pressure warning message.
Reactivate the tire pressure monitor-
ing system after correcting the tire
inflation pressure values
(page 269).
Tire pres.

Drive to workshop
The tire inflation pressure monitor is mal-
functioning.
Have the tire inflation pressure
monitor checked by an authorized
Mercedes-Benz Center.
A wheel without proper sensor was
installed.
Have the wheel checked.
Tire pressure
Please rectify
The tire inflation pressure is too low in one
or more tires.
Check and correct tire inflation pres-
sure as required (
page 266).
Warning!

The vehicle is equipped with the TIREFIT
kit.Preparing the vehicle
Park the vehicle in a safe distance from
moving traffic on a hard, flat surface
when possible.
Turn on the hazard warning flashers.
Turn the steering wheel so that the
front wheels are in a straight ahead po-
sition.
Set the parking brake.
Move the gear selector lever to P.
Turn off the engine (
page 58).
Remove the SmartKey from the starter
switch.
Open the driver’s door.
Have any passenger exit the vehicle at
a safe distance from the roadway.
Sealing tires with TIREFIT kit
Small tire punctures, particularly those in
the tread, can be sealed with TIREFIT.
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.
