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 345).
MOExtended tires may only be used in con-
junction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If a pressure loss warning message
appears in the multifunction display: R
observe the instructions in the display mes-
sages ( Y
page 250). R
check the tire for damage. R
if driving on, observe the following notes.
The driving distance possible in run-flat mode
is approximately 50 miles (80 km) when the
vehicle is partially laden. When the vehicle is
fully laden it is approximately 19 miles
(30 km).
In addition to the vehicle load, the driving dis-
tance possible depends upon: R
vehicle speed R
road condition R
outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving condi-
tions or maneuvers, or it can be increased
through a moderate style of driving.
The driving distance possible in run-flat mode
is counted from the moment the tire pressure
loss warning appears in the multifunction dis-
play. Flat tire 311

! Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission.
Vehicles with 4MATIC may only either be
towed away with both axles on the ground or
be loaded up and transported.
If the vehicle's transmission, front, or rear
axle is damaged, have the vehicle transported
on a truck or trailer.
In the event of damage to the electrical
system:
If the battery is defective, the automatic
transmission will be locked in position P . To
shift the automatic transmission to position
N , you must provide power to the vehicle's
electrical system in the same way as when
jump-starting ( Y

Tire pressure
Tire pressure specifications
Important safety notes
G WARNING
Underinflated or overinflated tires pose the
following risks: R
the tires may burst, especially as the load
and vehicle speed increase. R
the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction. R
the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel: R
monthly, at least R
if the load changes R
before beginning a long journey R
under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
i The data on the Tire and Loading Infor-
mation placard and tire pressure table
shown here are examples. Tire pressure
specifications are vehicle-specific and may
deviate from the data shown here. The tire
pressure specifications that are valid for
your vehicle can be found on the Tire and
Loading Information placard and tire pres-
sure table on the vehicle.
General notes
The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.
Further information on tire pressures can be
obtained at a qualified specialist workshop. Tire and Loading Information placard
C
Recommended tire pressures
The Tire and Loading Information placard is
on the B-pillar on the driver's side
( Y
page 339).
The Tire and Loading Information placard con-
tains the recommended tire pressures for
cold tires. The recommended tire pressures
are valid for the maximum permissible load
and up to the maximum permissible vehicle
speed.
Tire pressure table
The tire pressure table is on the inside of the
fuel filler flap. It shows the tire pressure for all
tires permitted at the factory for this vehicle;
see illustration (example).
The tire pressure table contains the recom-
mended pressures for cold tires for various
operating conditions, i.e. differing load and
speed conditions.
If a tire size precedes a tire pressure, the fol-
lowing tire pressure information is only valid
for that tire size; see illustration (example).332
Tire pressure
Wheels and tires

The tires are cold: R
if the vehicle has been parked with the tires
out of direct sunlight for at least three
hours and R
if the vehicle has not been driven further
than 1 mile (1.6 km)
The tire temperature changes depending on
the outside temperature, the vehicle speed
and the tire load. If the tire temperature
changes by 18 ‡ (10 †), the tire pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi). Take this into account when check-
ing the pressure of warm tires. Only correct
the tire pressure if it is too low for the current
operating conditions. If you check the tire
pressure when the tires are warm, the result-
ing value will be higher than if the tires were
cold. This is normal. Do not reduce the tire
pressure to the value specified for cold tires.
The tire pressure would otherwise be too low.
Observe the recommended tire pressures for
cold tires: R
on the Tire and Loading Information placard
on the B-pillar on the driver's side R
in the tire pressure table on the fuel filler
flap ( Y
page 168)
Underinflated or overinflated tires
Underinflated tires
G WARNING
Tires with pressure that is too low can over-
heat and burst as a consequence. In addition,
they also suffer from excessive and/or irreg-
ular wear, which can severely impair the brak-
ing properties and the driving characteristics.
There is a risk of an accident.
Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires may: R
overheat, leading to tire defects R
adversely affect handling R
wear excessively and/or unevenly R
have an adverse effect on fuel consumption
Overinflated tires
G WARNING
Tires with excessively high pressure can burst
because they are damaged more easily by
road debris, potholes etc. In addition, they
also suffer from irregular wear, which can
severely impair the braking properties and the
driving characteristics. There is a risk of an
accident.
Avoid tire pressures that are too high in all the
tires, including the spare wheel.
Overinflated tires may: R
increase the braking distance R
adversely affect handling R
wear excessively and/or unevenly R
have an adverse effect on ride comfort R
be more susceptible to damage
Maximum tire pressures
C
Example: maximum permissible tire pres-
sure
Never exceed the maximum permissible tire
inflation pressure. Always observe the rec-
ommended tire pressure for your vehicle
when adjusting the tire pressure
( Y
page 332).

Checking the tire pressures
Important safety notes Observe the notes on tire pressure
( Y
page 332).
Information on air pressure for the tires on
your vehicle can be found: R
on the vehicle's Tire and Loading Informa-
tion placard on the B-pillar R
in the tire pressure table in the fuel filler flap
( Y
page 168) R
in the "Tire pressure" section
Checking tire pressures manually To determine and set the correct tire pres-
sure, proceed as follows: X
Remove the valve cap of the tire that is to
be checked. X
Press the tire pressure gauge securely onto
the valve. X
Read the tire pressure and compare it to
the recommended value on the Tire and
Loading Information placard or the tire
pressure table ( Y
page 332).X
If the tire pressure is too low, increase the
tire pressure to the recommended value. X
If the tire pressure is too high, release air.
To do so, press down the metal pin in the
valve, using the tip of a pen for example.
Then check the tire pressure again using
the tire pressure checker. X
Screw the valve cap onto the valve. X
Repeat these steps for the other tires.
Tire pressure loss warning system
General notes
While the vehicle is in motion, the tire pres-
sure loss warning system monitors the set
tire pressure using the rotational speed of the
wheels. This enables the system to detect
significant pressure loss in a tire. If the speed
of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning
message will appear in the multifunction dis-
play.
You can recognize the tire pressure loss warn-
ing by the Run Flat Indicator Active
Press 'OK' to Restart message in the
multifunction display in the Serv.
menu.
Information on the message display can be
found in the "Restarting the tire pressure loss
warning system" section ( Y
page 336).
Important safety notes The tire pressure warning system does not
warn you of an incorrectly set tire pressure.
Observe the notes on the recommended tire
pressure ( Y
page 332).
The tire pressure loss warning does not
replace the need to regularly check the tire
pressure. An even loss of pressure on several
tires at the same time cannot be detected by
the tire pressure loss warning system.
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tire is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering movements.
The function of the tire pressure loss warning
system is limited or delayed if: R
snow chains are mounted on your vehicle's
tires. R
road conditions are wintry. R
you are driving on sand or gravel. R
you adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration). R
you are driving with a heavy load (in the
vehicle or on the roof). Tire pressure 335

sure monitor warns you if the pressure drops
in one or more of the tires. The tire pressure
monitor only functions if the corresponding
sensors are installed in all wheels.
Information on tire pressures is displayed in
the multifunction display. After a few minutes
of driving, the current tire pressure of each
tire is shown in the Serv. menu of the multi-
function display, see illustration (example).
