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 with collapsible tire
mounted. Adapt your driving style accord-
ingly.
The spare wheel with collapsible tire is for
temporary use only. When driving with spare
wheel with collapsible tire mounted, ensure
proper tire inflation pressure and do not ex-
ceed vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
with collapsible tire replaced with a regular
road wheel.
Never operate the vehicle with more than
one spare wheel with collapsible tire mount-
ed.

Preparing the vehicle
Prepare the vehicle as described
(page 388).

Take the collapsible tire, wheel wrench,
wheel bolts, jack, and electric air pump
out of the trunk (
page 369).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 369).
When changing wheel on a level sur-
face:

Place the wheel chock in front of
and another sizable object behind
the wheel that is diagonally oppo-
site to the wheel being changed.
When changing wheel on a hill:

Place the wheel chock and another
sizable object on the downhill side
blocking both wheels of the other
axle.
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 the jack arm is fully
seated in the jack take-up bracket. Always
lower the vehicle onto sufficient capacity
jackstands before working under the vehi-
cle.

collapsible tire (located in trunk with
spare wheel)

Clean contact surfaces of wheel and
wheel hub.
!Do not place wheel bolts in sand or dirt.
This could result in damage to the bolt
and wheel hub threads.
!Wheel bolts2 must be used when
mounting the spare wheel with
collapsible tire. The use of any wheel
bolts other than wheel bolts2 for the
spare wheel with collapsible tire will
physically damage the vehicle’s
brakes. !To avoid paint damage, place wheel flat
against hub and hold it there while in-
stalling first wheel bolt.

Never charge a battery while still installed in
the vehicle unless the accessory battery
charge unit approved by Mercedes-Benz is
being used. Gases may escape during charg-
ing and cause explosions that may result in
paint damage, corrosion or personal injury.
An accessory battery charge unit specially
adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available, permitting the charging of the bat-
tery in its installed position. Contact an
authorized Mercedes-Benz Center for infor-
mation and availability. Charge battery in
accordance with the separate instructions
for the accessory battery charger.

Do not smoke.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 294).
!Never invert the terminal connections.
iVehicles with automatic transmission*:
Do not tow-start vehicle.

401 Practical hints
Towing the vehicle
Towing the vehicle
Mercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment.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 only so far as
necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.
!Vehicles with automatic transmission*:
Do not tow-start vehicle.!Use flatbed or wheel lift/dolly equip-
ment with the SmartKey in the starter
switch in 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 86) and the automatic central
locking (
page 97).
!To be certain to avoid a possibility of
damage to the transmission, however,
we recommend the drive shaft be dis-
connected at the rear axle drive flange
for any towing beyond a short tow to a
nearby garage.
!If the vehicle is towed with the front
axle raised, the engine must be shut off
(SmartKey in starter switch
position0or1). 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 gear selector lever*
must be in positionN (manual trans-
mission: gear shift lever in neutral posi-
tion) and the SmartKey must be in
starter switch position1.
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).

402 Practical hintsTowing the vehicleWarning!
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.iTo signal turns while being towed with
the hazard warning flasher in use,
switch on ignition and activate the
combination switch for the left or right
turn signal 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-
ing:
With the automatic central locking acti-
vated and the SmartKey in starter
switch position2, the vehicle doors
lock if the left front wheel as well as the
right rear wheel are turning at vehicle
speeds of approx. 9 mph (15 km/h) or
more.
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking (
page 97).
Switch off the tow-away alarm
(
page 86).
The vehicle should only be towed using
a properly installed towing eye bolt.
Never attach a tow cable, tow rope or
tow rod to the vehicle chassis, frame or
suspension parts.
