Do not drive faster than 50 mph
(80 km/h).

Drive to the side of the road and select
a higher vehicle level (
page 232).
Depending on the type of malfunction,
this may raise the vehicle’s level.

Contact an authorized Mercedes-Benz
Center as soon as possible.
There is otherwise danger of an accident.
Malfunction

412 Practical hintsFlat tirePreparing 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.

Set the parking brake.

Move the gear selector lever to P.
Vehicles with SmartKey:

Turn off the engine (
page 60).

Remove the SmartKey from the starter
switch.Vehicles with KEYLESS-GO*:

Turn off the engine by pressing the
KEYLESS-GO* button on the gear
selector lever once (
page 60).

Open the driver’s door (this puts the
starter switch in position 0, same as
with the SmartKey removed 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 spare wheel
i
Open door only when conditions are safe to
do so.
Warning!
G
The dimensions of the spare wheel
(Minispare or collapsible tire) are different
from those of the road wheels. As a result,
the vehicle handling characteristics change
when driving with a spare wheel mounted.
Adapt your driving style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® when a Minis-
pare or collapsible tire is mounted.

419 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 Tire Pressure Monitor-
ing System (U.S. vehicles), Run Flat Indica-
tor (Canada vehicles), or Advanced Tire
Pressure Monitoring System* (Canada
only).!
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
vehicle 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.
i
When 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 444).

425 Practical hints
Towing the vehicle
Towing the vehicle
Mercedes-Benz recommends that the
vehicle be transported with all wheels off
the ground using flatbed or appropriate
wheel lift/dolly equipment. This method is
preferable to other types of towing.
When circumstances do not permit the
recommended towing methods, the
vehicle 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
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 automatic central (
page 165)
locking.
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 certain that the SmartKey
is in starter switch position2.
If the SmartKey is left in the 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.
Warning!
G
With the engine not running, there is no
power assistance for the steering system. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to steer the vehicle. Adapt your driv-
ing accordingly.!
If the vehicle is towed with the front axle
raised, the gear selector lever must be in
positionN and the engine must be shut off
(SmartKey in starter switch position0 or1).
Active braking action through the ESP
® may
otherwise seriously damage the brake system.
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 distances up to 30 miles
(50 km) and at a speed not to exceed 30 mph
(50 km/h).
