TIRE PRES. MONITOR
REACTIVE AFTER
CORRECTING PRESSURE
There was a tire inflation pressure warning
message.
The yellow warning lamp for the tire infla-
tion pressure monitor comes on and you
have not reactivated the system since the
last tire inflation pressure check.
Activate the tire inflation pressure monitor
after correcting the tire inflation pressure val-
ues (
page 294).
TIRE PRES. MONITOR
REACTIVATED
The tire inflation pressure monitor is using
the current pressure values as the basis for
monitoring.
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.

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!

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).

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.
Replacing jack support tube cover
Slide tongue of cover under the upper
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.

404 Technical dataRims and TiresUse only tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims 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, ex-
hibit dimensional variations and differ-
ent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle may be the result.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A placard with
the recommended tire inflation pres-
sures is located on the driver's door
B-pillar. Some vehicles may have sup-
plemental tire pressure information for
driving at high speeds (
page 293) or
for vehicle loads less than the maxi-
mum loaded vehicle condition. If such
information is provided, it can be found
on the placard located on the inside of
the fuel filler flap. The tire pressure
should be checked regularly and
should only be adjusted on cold tires.
Follow tire manufacturer’s mainte-
nance recommendation included with
vehicle.
