ManualThe passenger front air bag and the
passenger-side knee bag are
activated while driving even though a
child, small individual, or object below
the system’s weight threshold is on
the passenger seat, or the passenger
seat is empty. Objects on the seat or
forces acting on the seat may make
the system sense supplemental
weight.Stop the vehicle in a safe location as soon as possible and check the
passenger seat for the following:
Switch off the ignition (page 37).
Apply the parking brake (page 59).
Remove child and child restraint from passenger seat.
Make sure that no objects which are applying supplemental weight
onto the seat are present. The system may recognize such supple-
mental weight and sense that an occupant on the passenger seat is
of a greater weight than actually present.
Keep the seat unoccupied, close the passenger door and switch on
the ignition (
page 37).
Monitor the 75indicator lamp on the center console
(

Flat tire
Version 2
aDeflate button
bPressure gauge
If the tire inflation pressure is at least
20 psi (1.3 bar), inflate or deflate the
tire to correct tire inflation pressure
(see placard on the driver’s door
B-pillar):
To increase tire inflation pressure:
Switch on the electric air pump.
To decrease tire inflation pressure
(version 1): Open vent screwa
on pressure gaugeb
(
page 411).
To decrease tire inflation pressure
(version 2): Press yellow deflate
buttona located in air pump hous-
ing next to pressure gaugeb.Drive to the nearest qualified work-
shop, e.g. an authorized
Mercedes-Benz Center, to have the
damaged tire replaced.
Recommended duration of use:
A maximum of 300 miles (500 km) at
50 mph (80 km/h) or below with the
recommended tire inflation pressure.
Contact an authorized Mercedes-Benz
Center as soon as possible to obtain a
new TIREFIT kit.
Bring used TIREFIT materials to an
authorized Mercedes-Benz Center for
proper disposal.
Replace your TIREFIT container every
4 years. Replacement containers are
available at any authorized
Mercedes-Benz Center.
Warning!G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout)
because they are more likely to become
punctured 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.

Lowering the vehicle
Lower vehicle by turning the crank
counterclockwise until vehicle is
resting fully on its own weight.
Remove the jack.
1-5 Wheel bolts
Tighten the five wheel bolts evenly in
the direction of the arrow, following the
diagonal sequence illustrated
(1to5), until all bolts are tight.
Observe a tightening torque of
80 lb-ft (110 Nm).
Fully collapse the jack.
Place the vehicle tool kit, electric air
pump, and the jack back in the storage
compartment underneath the trunk
floor.
Wrap the damaged wheel in the protec-
tive sheet provided with the vehicle
tool kit and put the wheel in the trunk.
For information on storing the spare wheel
in the trunk after it has been replaced by a
regular road wheel, see “Storing the spare
wheel with collapsible tire” (
page 392).
Warning!G
Inflate the collapsible tire using the electric
pump (
page 418) before lowering the
vehicle.
Warning!G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
80 lb-ft (110 Nm).
iThe flat tire may be transported in the trunk
when the retractable hardtop is closed.
