Insert jack arm2 fully into tube
hole1 up to the stop.

Keeping jack in this position, turn
crank3 clockwise until the jack base
meets the ground. Make sure the jack
is vertical (plumb line).

Continue to turn the crank until the tire
is a maximum of 1.2 in (3 cm) from the
ground.
Warning!
G
Insert the jack arm fully into the jack sup-
port tube hole up to the stop. Otherwise the
vehicle may fall from the jack and cause per-
sonal injury or damage to the vehicle.
Warning!
G
The jack is intended only for lifting the vehi-
cle 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.

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 new wheel

Clean contact surfaces of wheel and
wheel hub.

Guide the spare wheel onto the align-
ment bolt and push it on.

Insert wheel bolts and tighten them
slightly.

Unscrew the alignment bolt, install last
wheel bolt and tighten slightly.
!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 in-
stalling 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.
Make sure you are using the correct wheel
bolts.
Warning!
G
Use only 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
tip over.

402 Practical hintsFlat tireLowering 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
110 lb-ft (150 Nm).

Before storing the jack in the trunk, it
should be fully collapsed, with handle
folded in.

Place the wheel bolt wrench, alignment
bolt and jack back in the vehicle tool kit
in the trunk and close the covering lid.Replacing jack support tube cover

Slide tongue of cover under the upper
edge of the tube opening.

Applying even pressure, press cover
until it snaps into place. Be careful not
to damage the locking tabs or clamp
the plastic retaining strap.
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
110 lb-ft (150 Nm).
!You can also screw the faulty wheel
down into the spare wheel well in the
trunk.
Do not activate the tire inflation pres-
sure monitor* until the depressurized
tire is no longer in the vehicle.

408 Practical hintsTowing the vehicleMercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment. This method is pref-
erable to other types of towing.When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the
ground or front wheels raised (except vehi-
cles with 4MATIC) only so far as necessary
to have the vehicle moved to a safe loca-
tion where the recommended towing
methods can be employed.
!Use flatbed or wheel lift/dolly equip-
ment with SmartKey in starter switch
turned to position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts.
Switch off the tow-away alarm
(page 89) and the automatic central
locking (
page 112).
Do not tow-start the vehicle.
!Vehicles with 4MATIC:
Do not tow with one axle raised. Doing
so could damage the transfer case,
which is not covered by the
Mercedes-Benz Limited Warranty.
All wheels must be on or off the ground.
Observe instructions for towing the ve-
hicle with all wheels on the ground.
!If the vehicle is towed with the front
axle raised (not permissible for vehicles
with 4MATIC), the engine must be shut
off (SmartKey in starter switch
position0 or 1). Otherwise the ESP will
immediately be engaged and will apply
the rear wheel brakes.
When towing the vehicle with all wheels
on the ground, the selector lever must
be in positionN and the SmartKey
must be in starter switch position2.
When towing the vehicle with all wheels
on the ground or the front axle raised,
the vehicle may be towed only for dis-
tances up to 30 miles (50 km) and at a
speed not to exceed 30 mph
(50 km/h).

409 Practical hints
Towing the vehicle
!
To be certain to avoid a possibility of
damage to the drive train, however, we
recommend the drive shaft be discon-
nected at the rear axle drive flange (ve-
hicles with 4MATIC: disconnected at
the front and rear axle drive flanges) for
any towing beyond a short tow to a
nearby garage.Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run


there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position2.
If the SmartKey is left in starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock, re-
move SmartKey from starter switch and re-
insert.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle. Adapt your driving accordingly.iThe gear selector lever will remain
locked in positionP and the SmartKey
will not turn in the starter switch if the
battery is disconnected or discharged.
See information on the battery
(page 403) or on jump starting
(page 406).
iTo signal turns while being towed with
the hazard warning flasher in use, turn
SmartKey in starter switch to
position2 and activate the combina-
tion switch for the left or right turn sig-
nal in the usual manner – only the
selected turn signal will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.

!When towing the vehicle with all wheels
on the ground, please note the follow-

With the automatic central locking acti-
vated and the SmartKey in starter
switch position2, or KEYLESS-GO*
start/stop button (
page 35) in
position2, the vehicle doors lock if the
le ft f ront whe el as wel l a s t he rig ht rea r
wheel are turning at vehicle speeds of
approximately 9 mph (15 km/h) or
more.
Switch off the tow-away alarm
(
page 89).
To prevent the vehicle doors from lock-
ing, deactivate the automatic central
locking (
page 112).
Towing of the vehicle should only be
done using the properly installed tow-
ing eye bolt. Never attach tow cable,
tow rope or tow rod to vehicle chassis,
frame or suspension parts.
