Mounting the Minispare wheel
i
Open the door only when conditions are safe
to do so.
Warning!
G
The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a Minispare wheel
mounted. Adapt your driving style accord-
ingly.
The Minispare wheel is for temporary use
only. When driving with Minispare wheel
mounted, ensure proper tire inflation
pressure and do not exceed a vehicle speed
of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the Minispare
wheel replaced with a regular road wheel.
Never operate the vehicle with more than
one Minispare wheel mounted.
Do not switch off the ESP
® when a Minis-
pare wheel is mounted.

Make sure to use the original length wheel
bolts when remounting the original wheel
after it has been repaired.!
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.
Make sure you are using the correct wheel
bolts.

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
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).i
Do not activate the tire inflation pressure
monitor (
page 511) until the depressurized
tire has been removed from the trunk.

642 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 only so far as necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.!
Do not tow-start the vehicle.
!
Use flatbed or wheel lift/dolly equipment
with SmartKey in starter switch turned to posi-
tion 0.
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 ESP
® (page 73), the tow-away
alarm (
page 76) and the automatic central
locking (page 313).
If the vehicle’s transmission is damaged, only
have it towed with the drive shaft disconnected.
!
Make sure that the electric parking brake is
released. If the electric parking brake is malfunc-
tioning, release it mechanically (
page 616).
!
In vehicles with KEYLESS-GO, insert the
SmartKey into the starter switch under the
KEYLESS-GO button and turn the SmartKey in
the starter switch to 0.
!
If the vehicle is towed with the front axle
raised, the engine must be shut off (SmartKey in
starter switch starter switch position 0 or 1).
Otherwise the ESP
®/ETS will immediately be en-
gaged and will apply the rear wheel brakes.
While towing, the battery must be connected and
charged. Otherwise:


you will not be able to switch on the ignition


you will not be able to engage the automatic
transmission in position N
When towing the vehicle with all wheels on the
ground, the automatic transmission must be
shifted to N and the SmartKey must be in starter
switch position2.
In vehicles with KEYLESS-GO*, you must use the
starter switch under the KEYLESS-GO* button
(
page 315).
When towing the vehicle with all wheels on the
ground or the front axle raised, the vehicle may
be towed only for distances up to 30 miles
(50 km) and at a speed not to exceed 30 mph
(50 km/h).
!
To be certain to avoid a possibility of dam-
age to the drivetrain, however, we recommend
the drive shaft be disconnected at the rear axle
drive flange for any towing beyond a short tow to
a nearby garage.

643 Practical hints
Towing the vehicle
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 brake sys-
tem


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 position 2 and automatic
locking is deactivated (
page 223).
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.i
The automatic transmission will remain
locked in position P and the SmartKey will not
turn in the starter switch if the consumer battery
is disconnected or discharged. See information
on the battery (
page 634) or on jump starting
(
page 639).
i
To signal turns while being towed with the
hazard warning flasher in use, turn SmartKey in
starter switch to position 2 and activate the com-
bination 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 hazard warn-
ing flasher will operate again.
!
When towing the vehicle with all wheels on
the ground, please note the following:
With the automatic central locking activated and
the SmartKey in starter switch position 2, or
KEYLESS-GO* start/stop button (
page 317)
in position 2, the vehicle doors lock if the left
front wheel as well as the right rear wheel are
turning at vehicle speeds of approximately
9mph (15km/h) or more.
Switch off the tow-away alarm (
page 76).
To prevent the vehicle doors from locking, deac-
tivate the automatic central locking
(
page 313).
Towing of the vehicle should only be done using
the properly installed towing eye bolt. Never at-
tach tow cable, tow rope or tow rod to vehicle
chassis, frame or suspension parts.
