Possible cause
Possible solution
TIRE PRES. MONITOR
CURRENTLY
UNAVAILABLE
The tire inflation pressure monitor* is un-
able to monitor the tire inflation pressure
due to:

the presence of several when sensors in
the vehicle


excessive wheel sensor temperatures


a nearby radio interference source


unrecognized wheel sensors installed

Remove any extra wheel sensors from the ve-
hicle
As soon as the causes of the malfunction have
been removed, the tire inflation pressure moni-
tor automatically becomes active again.
TIRE PRES. MONITOR
NOT OPERATIONAL DRIVE TO WORKSHOP
The tire inflation pressure monitor or a
wheel sensor is malfunctioning.

Have the tire inflation pressure monitor
checked by an authorized Mercedes-Benz
Center.
A wheel without proper sensor was in-
stalled.

Have the wheels checked.
Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle.
You may lose control of the vehicle. Contin-
ued driving with a flat tire will cause exces-
sive heat build-up and possibly a fire.

The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.

Preparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.

Turn on the hazard warning flashers.

Turn the steering wheel so that the
front wheels are in a straight ahead
position.

Set the parking brake.

Move the gear selector lever toP.
Vehicles with SmartKey:

Turn off the engine (
page 59).

Remove the SmartKey from the starter
switch.Vehicles with SmartKey with
KEYLESS-GO*:

Turn off the engine by pressing the
KEYLESS-GO* button on the gear se-
lector lever once (
page 59).

Open the driver’s door (this puts the
starter switch in position0, same as
with the SmartKey removed from the
starter switch). The driver’s door then
can be closed again.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Mounting the spare wheel
iOpen door only when conditions are
safe to do so.
Warning!
G
Never operate the vehicle with more than
one spare wheel mounted.
The spare wheel rim is for temporary use
only. Use for over a total of 12 000 miles
(20 000 km) (aggregate of all uses) may
cause wheel rim failure leading to an acci-
dent and possible injuries.
The spare wheel should only be used tempo-
rarily and replaced with a regular road wheel
as quickly as possible.
CL 55 AMG, CL 65 AMG and Sport Pack-
age* only:
The spare wheel is for temporary use only.
When driving with spare wheel mounted, en-
sure proper tire inflation pressure and do
not exceed vehicle speed of 50 mph
(80 km/h).


382 Practical hintsFlat tirePreparing the vehicle
Take vehicle tool kit tray and vehicle
jack out of trunk.

Take the spare wheel out of wheel well
(page 366).
Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizable objects.
When changing wheel on a level surface:

Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
When changing wheel on a hill:

Place chocks behind the downhill sides
of both wheels of the axle not being
worked on.

Take the two-piece wheel wrench out
of the vehicle tool kit tray. Assemble
wheel wrench.

On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench).
The tube openings are located directly be-
hind the front wheel housings and in front
of the rear wheel housings.
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a mounted spare
wheel. Adapt your driving style accordingly.

1-5 Wheel bolts
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to5), until all bolts are tight.
Observe a tightening torque of
110 lb-ft (150 Nm).

Before storing the jack in the trunk, it
should be fully collapsed, with handle
folded in.

Place the wheel bolt wrench, alignment
bolt and jack back in the vehicle tool kit
in the trunk and close the covering lid.

edge of the tube opening.

Applying even pressure, press cover
until it snaps into place. Be careful not
to damage the locking tabs or clamp
the plastic retaining strap.
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
110 lb-ft (150 Nm).
!You can also screw the faulty wheel
down into the spare wheel well in the
trunk.
Do not activate the tire inflation pres-
sure monitor until the depressurized
tire is no longer in the vehicle.
