properties)
General notes With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-
bearing capacity and the speed index
(Y
page 314).
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If the pressure loss warning message
appears in the multifunction display:
R Observe the instructions in the display
messages (Y page 226).
R Check the tire for damage.
R If driving on, observe the following notes.
The maximum driving distance is
approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
18 miles (30 km) when the vehicle is fully
laden.
In addition to the vehicle load, the driving
distance possible depends upon:
R Speed
R Road condition
R Outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving
conditions/maneuvers, or it can be increased
through a moderate style of driving. Flat tire
283Breakdown assistance

The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tire pressure loss warning
appears in the multifunction display.
You must not exceed a maximum speed of
50 mph (80 km/h).
i
When replacing one or all tires, make sure
that you use only tires:
R of the size specified for the vehicle and
R marked "MOExtended"
If a tire has gone flat and cannot be
replaced with a MOExtended tire, a
standard tire may be used as a temporary
measure. Make sure that you use the
proper size and type (summer or winter
tire).
Important safety notes G
WARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when
cornering, accelerating quickly and when
braking. There is a risk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This applies in particular to a laden
vehicle.
Stop driving in emergency mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The
defective tire must be replaced in every case. Battery (vehicle)
Important safety notes
Special tools and expert knowledge are
required when working on the battery, e.g.
removal and installing. You should therefore
have all work involving the battery carried out
at a qualified specialist workshop. G
WARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevan tsystems, e.g. the lighting
system, ABS (anti-lock braking system) or
ESP ®
(Electronic Stability Program). The
operating safety of your vehicle may be
restricted. You could lose control of the
vehicle, for example:
R braking
R in the event of abrupt steering maneuver
and/o rwhen the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar
incident, contact a qualified specialist
workshop immediately. Do not drive any
further. You should have all work involving the
battery carried out at aqualified specialist
workshop.
For further information about ABS and ESP ®
,
see (Y page 62) and ( Ypage 64). G
WARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly
explosive gases of a battery. There is a ris kof
an explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-
starting. 284

Information on driving
R If the vehicle is heavily loaded, check the
tire pressures and correct them if
necessary.
R While driving, pay attention to vibrations,
noises and unusual handling 296
OperationWheels and tires

For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Treadwea rindicators (TWI) are required by
law. Six indicators are positioned on the tire
tread. They are visible once the tread depth
is approximately 0008in (1.6 mm). If thi sisthe
case, the tire is so worn that it must be
replaced. Bar indicator
0002for tread wear is integrated
into the tire tread. Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same
type and make.
Exception: it is permissible to install a
different type or make in the event of a flat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics)" section
(Y page 283).
R Only mount tires of the correct size onto
the wheels.
R After mounting new tires, break them in at
moderate speeds for the first 60 miles
(100 km), as they only reach their full
performance after this distance.
R Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace the tires after six years at the
latest, regardless of wear. Observe the notes on the emergency spare
wheel (Y
page 328). MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires.
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system or with an active tire pressure
monitor and on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tires in the
event of a flat tire can be found in the
"Breakdown assistance" section
(Y page 283). Winter operation
Points to remember
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 320). Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your
vehicle to M+S tires. Using summer tires at
very cold temperatures could cause cracks to
form, thereby damaging the tires
permanently. Mercedes-Benz cannot accept
responsibility for this type of damage. M+S tires
G
WARNING
M+S tires with a tire tread depth of less than
000A in (4 mm) are not suitable for use in winter 298
