Mounting the spare wheel
Preparing the vehicle
Prepare the vehicle as described
(
page 401).
Take the spare wheel, wheel wrench,
wheel bolts, jack, and electric air pump
out of the trunk (
page 382).Lifting the vehicle
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizeable ob-
jects.
One wheel chock is included with the
vehicle tool kit (
page 383).
When changing wheel on a level surface:
Place one wheel chock or other size-
able object in front of and another
wheel chock or other sizeable object
behind the wheel that is diagonally
opposite to the wheel being changed.
Always try lifting the vehicle using the jack
on a level surface. However, should cir-
cumstances require you to do so on a hill,
place the wheel chock or other sizeable
object and the other wheel chock or other
sizeable object as follows:
Place wheel chocks and other sizeable
objects on the downhill side blocking
both wheels of the axle not being
worked on.
Warning!G
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 spare wheel with
collapsible tire mounted. Adapt your driving
style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire inflation pressure and do
not exceed vehicle speed of 50 mph
(80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® when a spare
wheel is mounted.

Jack up the vehicle until the wheel is a
maximum of 1.2 in (3 cm) from the
ground.Removing the wheel

page 382).
Remove the remaining bolts.
Remove the wheel.Mounting the spare wheel
1Wheel bolt for light alloy rims
2Wheel bolt for spare wheel with
collapsible tire (located under plastic
cover on the outside of spare wheel
rim)
Warning!G
The jack is intended only for lifting the
vehicle briefly for wheel changes. It is not
suited for performing maintenance work
under the vehicle.

Never start the engine when the vehicle
is raised.

Never lie down under the raised vehicle.
!Do not place wheel bolts in sand or dirt. This
could result in damage to the bolt and wheel hub
threads.
Warning!G
Inflate collapsible tire only after the wheel is
properly mounted.
Inflate the collapsible tire using the electric
pump (
page 411) before lowering the
vehicle.

410 Practical hints
Flat tire
Clean contact surfaces of wheel and
wheel hub.
Guide the spare wheel onto the align-
ment bolt and push it on.
Insert the wheel bolts and tighten them
slightly.
!Wheel bolts2 must be used when mount-
ing the spare wheel with collapsible tire. The use
of any wheel bolts other than wheel bolts2 for
the spare wheel with collapsible tire will physi-
cally damage the vehicle’s brakes.
!To avoid paint damage, place wheel flat
against hub and hold it there while installing first
wheel bolt.
Warning!G
Always replace wheel bolts that are
damaged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be
repaired immediately. Do not continue to
drive under these circumstances! Contact
an authorized 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.

412 Practical hints
Flat tire
PressI on electric air pump switch2.
The electric air pump switches on and
inflates the collapsible tire.
Inflate the collapsible tire to approxi-
mately 51 psi (3.5 bar).
This takes about 5 minutes. Air
hose4 and union nut5 can become
hot during inflation. Exercise proper
caution to avoid burning yourself when
using the equipment.
Press0 on electric air pump switch2.
Turn the SmartKey in the starter switch
to position0.
The electric air pump is switched off.
If the tire inflation pressure is above
51 psi (3.5 bar), release excess tire
inflation pressure using the vent screw
on air hose4.
Detach the electric air pump.
Reinstall tire valve cap.
Store electrical plug3 and air
hose4 behind flap 1 and place the
electric air pump back in the trunk.
Lower the vehicle (page 413).
!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
collapsible 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 6 minutes without interruption. Otherwise it
may overheat.
You may operate the electric air pump again
after it has cooled off.Warning!G
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being over-
heated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.

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 385).
Warning!G
Inflate the collapsible tire using the electric
pump (
page 411) 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.
