1Wheel bolt for light alloy rims
2Wheel bolt for spare wheel with
collapsible tire (located in trunk with
spare wheel)
Clean contact surfaces of wheel and
wheel hub.
Guide spare wheel onto the alignment
bolt and push it on.
Insert wheel bolts and tighten them
slightly.
!
Wheel bolts2 must be used when
mounting the spare wheel. The use of
any wheel bolts other than wheel
bolts2 for the spare wheel 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.
Make sure to use the correct wheel bolts.

409 Practical hints
Flat tire
Insert electrical plug 3 into vehicle
cigarette lighter socket (
page 263).
Turn the SmartKey in the starter switch
to position1.
PressI on electric air pump switch 2.
The electric air pump should now
switch on and inflate the collapsible
tire.
Inflate the tire to approximately 51 psi
(3.5 bar).
This takes about 5 minutes for the col-
lapsible tire. Air hose 4 and union
nut5 can become hot during infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.
Press0 on electric air pump switch 2.
Turn the SmartKey in the starter switch
to position0.
If the tire pressure is above 51 psi
(3.5 bar), release excess tire pressure
using the vent screw.
Detach the electric air pump.
Store the electrical plug and the air
hose behind the flap and place the
electric air pump back in the trunk.
!
The cigarette lighter (page 262) is
not designed for use with the electric
air pump. Use the power outlet in the
rear passenger compartment
(
page 263) for electric air pump
operation.
!
Do not operate the electric air pump
longer than 6 minutes without interrup-
tion. Otherwise it may overheat.
You may operate the electric 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.

counterclockwise until vehicle is
resting fully on its own weight.
Remove the jack.1 - 5Wheel bolts
Tighten the five wheel bolts evenly,
following the diagonal sequence
illustrated (1to5), until all bolts are
tight. Observe a tightening torque
of 80 lb-ft (110 Nm).Before storing the jack, it should be fully
collapsed, with handle folded in (storage
position) (
page 381).
Store the jack and the other vehicle
tools in the trunk.
Warning!G
Inflate collapsible tire only after the wheel is
properly mounted.
Inflate the collapsible tire using the electric
pump (
page 408) before lowering the ve-
hicle.
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).
