Remove the SmartKey from the starter
switch.Vehicles with SmartKey with
KEYLESS-GO*:

Turn off the engine by pressing the
KEYLESS-GO* start/stop button on the
gear selector lever once (
page 64).

Open the driver’s door (this puts the ig-
nition in position0, same as with the

closed again.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Mounting the spare wheel
i
Open door only when conditions are safe to
do so.
Warning!
G
The dimensions of the spare wheel
(Minispare or collapsible tire) are different
from those of the road wheels. As a result,
the vehicle handling 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
Minispare or collapsible tire is mounted.

Flat tire
Preparing the vehicle
Prepare the vehicle as described
(page 452).
Vehicles with Minispare wheel
(except E 63 AMG):

Take the Minispare wheel, wheel
wrench and the jack out of the trunk
(page 432).
Vehicles with collapsible tire
(E 63 AMG only):

Take the collapsible tire, wheel wrench,
jack and electric air pump out of the
trunk (
page 432).Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizeable objects.
One wheel chock is included with the
vehicle tool kit (
page 434).
When changing wheel on a level surface:

Place the wheel chock in front of and
another 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
circumstances require you to do so on a
hill, place the wheel chock and the other
sizeable object as follows:

Place the wheel chock and another
sizeable object on the downhill side
blocking both wheels of the axle not
being worked on.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into either side 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, es-
pecially on hills. Always try to use the jack
on level surface. Be sure that 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.


454 Practical hintsFlat tire
On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench). The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings.
1Jack take-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.Warning!
G
Position the jack only on the jack take-up
brackets designed for this purpose.
If the jack is not properly positioned, the ve-
hicle may slip off of the jack.

Removing the wheel
1Alignment bolt
Unscrew upper-most wheel bolt and re-
move.

Replace this wheel bolt with alignment
bolt1 supplied in the tool kit.

Remove the remaining bolts.

Remove the wheel.Mounting the spare wheel

Clean contact surfaces of wheel and
wheel hub.

Guide the spare wheel onto the align-
ment bolt and push it on.
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.
!
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 dam-
aged or rusted.
Never apply oil or grease to wheel bolts.
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.


456 Practical hintsFlat tire
Insert wheel bolts and tighten them
slightly.

Unscrew the alignment bolt, install last
wheel bolt and tighten slightly.Vehicles with collapsible tire
(E 63 AMG only):

Continue the procedure by following
the instructions under “Inflating the
collapsible tire” (
page 456) and then
“Lowering the vehicle” (
page 458).
Vehicles with Minispare wheel
(except E 63 AMG):

Continue the procedure by following
the instructions under “Lowering the
vehicle” (
page 458).Inflating the collapsible tire
(E 63 AMG only)

Take the electric air pump out of the
trunk (
page 432).
Warning!
G
Only use Genuine equipment
Mercedes-Benz wheel bolts. 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.
Warning!
G
Inflate collapsible tire only after the wheel is
properly mounted.
Inflate the collapsible tire using the electric
air pump before
lowering the vehicle.
Warning!
G

3Electrical plug
4Air hose with pressure gauge and vent
screw
5Union nut
Open flap 1 on electric air pump.

Pull out electrical plug 3 and air hose
with pressure gauge 4.

Remove the valve cap from the
collapsible tire valve.

Screw union nut5 onto the collaps-
ible tire valve.

Insert electrical plug 3 into vehicle
cigarette lighter socket.

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.
!
Do not operate the electric air pump longer
than 8 minutes without interruption. Otherwise it
may overheat.
You may operate the electric air pump again af-
ter it has cooled off.
Warning!
G
Follow recommend tire 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.


458 Practical hintsFlat tire
Store the electrical plug 3 and the air
hose 4 behind the flap 1 and place
the electric air pump back in the desig-
nated storage space underneath the
trunk floor (
page 432).
Lowering the vehicle

Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.

Remove the jack.
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, it should be fully
collapsed, with handle folded in (storage
position).

Store the jack and the other vehicle
tools in the designated storage space
underneath the trunk floor
(page 432).
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).
i
Wrap the damaged wheel in the protective
film that comes with the spare wheel and put the
wheel in the trunk.
You can also place the damaged wheel down into
the spare wheel well. In this case, you must stow
the holder from the spare wheel well in the trunk.
Vehicles with Advanced TPMS* (Canada only):
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.
