Caution
Tire defect
Vehicles with Advanced TPMS*:
One or more tires are deflating. The respec-
tive tire is shown in the multifunction dis-
play.

Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.

If necessary, change the wheel (
page 629).
Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
may lose control of the vehicle. Continued
driving with a flat tire will cause excessive
heat build-up and possibly a fire.

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 flashers.

Turn the steering wheel so that the
front wheels are in a straight ahead
position.

Shift the automatic transmission toP.

Turn off the engine (
page 365).

Remove the SmartKey from the starter
switch.
Vehicles with SmartKey with
KEYLESS-GO*:
Turn off the engine by pressing the
KEYLESS-GO* button once
(page 366).

Open the driver’s door (this puts
the starter switch in position0,
same as with the SmartKey re-
moved from the starter switch). The
driver’s door then can be closed
again.

Have any passenger exit the vehicle at
a safe distance from the roadway.
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.

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.
