Damaged wheel hub threads should be re-
paired immediately. Do not continue to drive
under these circumstances! Contact an au-
thorized Mercedes-Benz Center or call
Roadside Assistance.
Incorrect wheel bolts or improperly tight-
ened wheel bolts can cause the wheel to
come off. This could cause an accident. Be
sure to use the correct wheel bolts.

Mercedes-Benz wheel bolts. They are identi-
fied by the Mercedes star. Other wheel bolts
may come loose.
Do not tighten the wheel bolts when the ve-
hicle is raised. Otherwise the vehicle could
fall off the jack.!

Turn the SmartKey in the starter switch
to position1.
or

Press the KEYLESS-GO* start/stop
button on the gear selector lever once
without depressing the brake pedal.

PressI on the electric air pump
switch2.
The electric air pump should now
switch on and inflate the tire.

Inflate the spare tire:

SL 550 to 36 psi (2.5 bar)


SL 600, SL 55 AMG, SL 55 AMG
(Performance Package*), and
SL 65 AMG to 51 psi (3.5 bar)
This takes about 5 minutes.
Air hose4 and union nut5 can be-
come hot during inflation. Exercise
proper caution to avoid burning your-
self when using the equipment.

Press0 on the electric air pump
switch2.

Turn the SmartKey in the starter switch
to position0.
or

Press KEYLESS-GO* start/stop button
on the gear selector lever twice without
depressing the brake pedal.
The electric air pump should now be
switched off.

If the spare tire inflation pressure is
above the recommended tire inflation
pressure for the respective collapsible
tire (
page 440), release excess spare
tire inflation pressure using the vent
screw.

Detach the electric air pump.

Stow the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.
!
Compare the recommended tire inflation
pressure for your vehicle with the tire inflation
pressure on the yellow label located on the spare
wheel rim.
If the tire inflation pressure on the yellow label
on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the tire to
the recommended tire inflation pressure given
on the yellow label on the spare wheel rim.
!
Do not operate the electric air pump longer
than 8 minutes without interruption. Otherwise it
may overheat.
You may operate the air pump again after it has
cooled off.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured 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.


412 Practical hintsFlat tireLowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until the full weight of the
vehicle is resting on the ground.

Pull the jack out of the jack support
tube.
1 - 5 Wheel bolts

Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of 96 lb-ft
(130 Nm).

Before storing the jack in the trunk,
crank back to storage position and fold
in the arm.
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

Vehicles with TPMS or Advanced TPMS*:
Do not activate the tire inflation pressure moni-
tor until a full size wheel/tire with functioning
sensor has been placed back into service on 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
96 lb-ft (130 Nm).Warning!
G
When turning the wheel wrench to tighten
the wheel bolts, make sure you position
hands on the wrench in such a way that you
avoid injury to yourself, such as scraping
your hands against the wheel. Make sure
turning the wheel wrench will not scratch or
damage the wheel rim.
