! Always use wheel bolts ; to mount the
collapsible spare wheel. Using other wheel
bolts to mount the collapsible spare wheel could damage the brake system.
Be sure to use the original-length wheel bolts
when re-mounting the original wheel after it
has been repaired.
! To prevent damage to the paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt.
X Clean the wheel and wheel hub contact
surfaces.
X Place the new wheel on the wheel hub and
push it on.
X Tighten the wheel bolts until they are fin-
ger-tight.
X Inflate the collapsible spare wheel
(Y page 367).
Only then lower the vehicle.
Lowering the vehicle
GWARNING
The wheels could work loose if the wheel nuts and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
! Inflate the collapsible spare wheel using
the tire inflation compressor before lower-
ing the vehicle. The wheel rim could other-
wise be damaged.
X Place the ratchet wrench onto the hexagon
nut of the jack so that the letters AB are
visible.
X Turn the ratchet wrench until the vehicle is
once again standing firmly on the ground.
X Place the jack to one side.
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated ( :
to A ). The tightening torque must be
110 lb-ft (150 Nm) .
X Turn the jack back to its initial position and
store it together with the rest of the tire-
change tool kit in the cargo compartment.
X Transport the faulty wheel in the cargo
compartment.
X Check the tire pressure of the newly moun-
ted wheel and adjust it if necessary.
Observe the recommended tire pressure
( Y page 336).
For further information on stowing the col-
lapsible spare wheel, see ( Y page 367).
iWhen you are driving with the emergency
spare wheel mounted, the tire pressure
monitor cannot function reliably. Only
restart the tire pressure monitor when the
defective wheel has been replaced with a
new wheel. All wheels mounted must be
equipped with functioning sensors.

Inflating the collapsible spare wheel
! Inflate the collapsible spare wheel using
the tire inflation compressor before lower-
ing the vehicle. The wheel rim could other-
wise be damaged.
X Pull connector ? and the air hose out of
the housing.
X Remove the cap from the valve on the col-
lapsible spare wheel.
X Screw union nut : on the air hose onto the
valve.
X Make sure on/off switch A of the tire
inflation compressor is set to 0.
X Insert plug ? into the socket of the ciga-
rette lighter ( Y page 284) or into a 12 V
power socket ( Y page 284) in your vehicle.
X Make sure that the SmartKey is in position
1 (Y page 149) in the ignition lock.
X Press on/off switch A on the tire inflation
compressor to I.
The tire inflation compressor is switched
on. The tire is inflated. The tire pressure is
shown on pressure gauge =.
! Do not operate the tire inflation compres-
sor for longer than eight minutes at a time
without a break. It may otherwise overheat.
The tire inflation compressor can be oper-
ated again once it has cooled down.
X Inflate the tire to the specified tire pres-
sure. The specified tire pressure is printed on the
yellow label of the emergency spare wheel.
X When the specified tire pressure has been
reached, press on/off switch A on the
electric air pump to 0.
The tire inflation compressor is switched
off.
X Turn the SmartKey to position 0 in the igni-
tion lock.
X If the tire pressure is higher than the speci-
fied pressure, press pressure release but-
ton ; until the correct tire pressure has
been reached.
X Unscrew union nut : on the air hose from
the valve.
X Screw the cap onto the valve of the col-
lapsible spare wheel again.
X Stow plug ? and the air hose in the lower
section of the blower housing.
X Stow the tire inflation compressor in the
vehicle.
Stowing a used collapsible spare wheel
Take the following steps to stow a used col-
lapsible spare wheel. Otherwise, the collaps-
ible spare wheel will not fit in the spare wheel
well. Mercedes-Benz recommends that you
have this work carried out at a qualified spe-
cialist workshop.
! Only place the collapsible spare wheel in
the vehicle when it is dry. Otherwise, mois-
ture may get into the vehicle.
X Remove the valve extractor from the vehi-
cle tool kit.
X Unscrew the valve cap from the valve.
X Unscrew the valve insert from the valve and
release the air.
iFully deflating the tires can take a few
minutes.
X Screw the valve insert back into the valve.
X Screw the valve cap back on.
