Flat tire
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 flasher
(
page 115).
Turn the steering wheel so that the
front wheels are in a straight ahead
position.
Set the parking brake (page 54).
Move the gear selector lever toP
(manual transmission: to first or
reverse gear).
Turn off the engine (page 55).
Remove the SmartKey from the starter
switch.
Have any passenger exit the vehicle at
a safe distance from the roadway.
Mounting the Minispare wheel
Preparing the vehicle
Prepare the vehicle as described
(
page 377).
Take the wheel wrench, alignment bolt,
collapsible wheel chock, and the jack
out of the trunk (
page 356).
Take the Minispare wheel and wheel
bolts out of the trunk (
page 359).
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
Minispare wheel is mounted.
iOpen doors only when conditions are safe to
do so.

382 Practical hints
Flat tire
MOExtended system*
The MOExtended system allows you to
continue driving your vehicle even if there
is a total loss of pressure in one or more
tires.
You may only use the MOExtended system
in conjunction with the Run Flat Indicator*.
!The maximum distance in emergency mode
depends on the vehicle’s load. It is 30 miles
(50 km) if the vehicle is partially loaded and
18 miles (30 km) if the vehicle is fully loaded.
The point at which the maximum driving distance
begins in emergency mode is when the warning
message appears in the multifunction display
indicating that there is a loss of tire inflation
pressure.
Do not exceed the maximum speed of 50 mph
(80 km/h).
Warning!G
In emergency mode, your vehicle’s driving
characteristics are diminished in such situa-
tions as:

driving around curves

while braking

while accelerating rapidly
Therefore, your driving style must be adapt-
ed accordingly. Avoid abrupt steering and
driving maneuvers, as well as driving over
obstacles (road curbs, potholes, or off-road
areas). This is especially important if the ve-
hicle is heavily loaded.
The emergency driving distance that can be
achieved greatly depends on the demands
placed on the vehicle. Depending on speed,
load, driving maneuvers, road conditions,
outside temperature, etc., the distance can
be significantly shorter or, if the vehicle is
driven cautiously, somewhat longer.
Do not continue driving in emergency mode
if

you notice knocking sounds

the vehicle starts to shake

smoke develops and you smell rubber

ESP® is intervening continuously

you notice tears on the tire sidewalls
After driving in emergency mode, you must
have the rims inspected by an authorized
Mercedes-Benz Center to check if they are
suitable for further use. The failed tire must
be replaced in any case.
iWhen replacing individual or all tires on the
vehicle, make sure only matching tires marked
with “MOExtended” are mounted in the size
specified for your vehicle (
page 403).

389 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 power
supply or in the vehicle’s electrical
system
as that will be necessary to adequately
control 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,
remove SmartKey from starter switch and
reinsert.
iTo signal turns while being towed with the
hazard warning flasher in use, switch on the igni-
tion 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 hazard warn-
ing flasher will operate again.
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.
!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 position2, the ve-
hicle 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 doors from locking, deac-
tivate the automatic central locking
(
page 143).
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.
iIf the battery is disconnected or discharged

the SmartKey will not turn in the starter
switch. For more information, see “Battery”
(
page 383) and “Jump starting”
(
page 386).

the gear selector lever will remain locked in
positionP. For information on manually un-
locking the transmission gear selector lever
see (
page 363).
