Flat tire
Preparing the vehicle
Park the vehicle in a safe distance from
moving traffic on a hard, flat surface
when possible.
Turn on the hazard warning flasher
(
page 119).
Turn the steering wheel so that the
front wheels are in a straight ahead
position.
Set the parking brake (page 54).
Move the gear selector lever toP.
Turn off the engine (page 56).
Remove the SmartKey from the starter
switch.
Have any passenger exit the vehicle at
a safe distance from the roadway.
Mounting the spare wheel
Preparing the vehicle
Prepare the vehicle as described
(
page 404).
Take the collapsible tire, wheel wrench,
wheel bolts, jack, and electric air pump
out of the trunk (
page 380).
Warning!G
The dimensions of the spare wheel with col-
lapsible tire are different from those of the
road wheels. As a result, the vehicle han-
dling characteristics change when driving
with a spare wheel mounted. Adapt your
driving style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a 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.
i
Open doors only when conditions are
safe to do so.

Lifting the vehicle
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizable objects.
One wheel chock is included with the
vehicle tool kit (
page 380).
When changing wheel on a level surface:
Place the wheel chock in front of and
another sizable 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 and the other size-
able object as follows:
Place wheel chocks and another siz-
able object on the downhill side block-
ing both wheels of the axle not being
worked on.
On wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with
wrench).
Warning!G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.

The jack take-up brackets are located
directly behind the front wheel housings
and in front of the rear wheel housings.
1Take-up bracket
2Jack
Place jack2 on firm ground.
Position jack2 under take-up
bracket1 so that it is always vertical
(plumb-line) as seen from the side,
even if the vehicle is parked on an
incline.
Jack up the vehicle until the wheel is a
maximum of 1.2 in (3 cm) from the
ground. Never start engine while
vehicle is raised.Removing the wheel
1Alignment bolt
Unscrew upper-most wheel bolt and
remove.
Replace this wheel bolt with alignment
bolt1 supplied in the tool kit.
Remove the remaining bolts.
Remove the wheel.
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 bolts
and wheel hub threads.

Mounting the spare wheel
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.
