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 conditions/
manoeuvres, 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 tyre pressure loss
warning appears in the multifunction display.
You must not exceed a maximum speed of
80 km/h.
i When replacing one or all tyres, observe the
following specifications for your vehicle's
tyres:
R size
R type and
R the "MOExtended" mark
If a tyre has gone flat and cannot be replaced
with an MOExtended tyre, a standard tyre
may be used as a temporary measure. Make
sure that you use the proper size and type
(summer or winter tyres).
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you fit
tyres that do not feature run-flat characteris-
tics, e.g. winter tyres. A TIREFIT kit can be
obtained from a qualified specialist work-
shop.
Important safety notes G
WARNING
When driving in emergency mode, the driving characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is a risk of accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving manoeu-
vres, and driving over obstacles (kerbs, pot-
holes, 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 tyre.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The faulty tyre must be replaced. TIREFIT kit
Important safety notes TIREFIT is a tyre sealant.
You can use TIREFIT to seal punctures of up to
4 mm, particularly those in the tyre tread. You
can use TIREFIT at outside temperatures down
to Ò20 †. G
WARNING
In the following situations, the tyre sealant is
unable to provide sufficient breakdown assis- tance, as it is unable to seal the tyre properly:
R there are cuts or punctures in the tyre
larger than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on a flat tyre.
There is a risk of an accident.
Do not drive any further. Contact a qualified
specialist workshop. G
WARNING
The tyre sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not inhale TIREFIT fumes. Keep tyre sealant away
from children. There is a risk of injury. Flat tyre

when stationary (hybrid vehicles)
Only PLUG-IN HYBRID vehicles are equipped
with a high-voltage battery. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
! Only charge the high-voltage battery in the
"Charging when stationary" mode. Do not
connect a battery charger to the high-voltage battery. Otherwise, the vehicle's high-voltage
electrical system could be damaged.
X Stop the vehicle if the internal combustion
engine is running.
The internal combustion engine drives the
electric motor. The electric motor is operating
as an alternator. The high-voltage battery is
charging.
If the high-voltage battery is too heavily dis-
charged, recharge the high-voltage battery to at least 60% of its capacity. In the "Charging when
stationary" operating mode, you can observe
the charge status of the high-voltage battery up to a maximum of 70% in the COMAND display
and in the multifunction display (Y page 264).396

not sag.
R Do not use steel cables or chains to tow
your vehicle. You could otherwise damage
the vehicle.
! Do not use the trailer tow hitch for recovery
or towing. Do not use the towing eye for
recovery. This could damage the vehicle. If in doubt, have the vehicle recovered using a
crane.
! When towing, pull away slowly and
smoothly. Pull the towed vehicle as straight as possible and not at an acute angle. If the trac-
tive power is too high, the vehicles could be
damaged.
When towing, it is preferable to use a rigid tow- ing bar as opposed to a tow rope. A rigid towing
bar helps to keep the tractive power low.
! To tow vehicles with KEYLESS-GO, use the
key instead of the Start/Stop button. The
automatic transmission may otherwise
switch to position Pwhen you open the driv-
er's or front-passenger door which could
damage the transmission.
! Vehicles with differential locks: make sure
the differential locks are in automatic mode.
When towing, the differential locks must not
be switched on. The transmission may other- wise be damaged.
! You may tow the vehicle for a maximum of
50km. A towing speed of 50 km/h must not
be exceeded.
For towing distances over 50 km, the entire
vehicle must be lifted up and transported.
Observe the legal requirements for the relevant countries when towing.
It is better to have the vehicle transported than
to have it towed.
If the vehicle has suffered transmission damage, have it transported on a transporter or trailer.
The automatic transmission must be in position
N when the vehicle is being towed away.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the key to position 2in the igni-
tion lock
R cannot release the electric parking brake
R cannot shift the automatic transmission to

Tyre pressure loss warning system
General notes While the vehicle is in motion, the tyre pressure
loss warning system monitors the set tyre pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in a tyre. 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 display.
You can recognise the tyre pressure loss warn-
ing by the Run Flat Indicator active
Run Flat Indicator active
Restart with OK
Restart with OK message which appears in
the Serv.
Serv. menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tyre pressure loss
warning system" section (Y page 410).
Important safety notes The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure
(Y page 408).
The tyre pressure loss warning does not replace the need to regularly check the tyre pressures.
An even loss of pressure on several tyres at the
same time cannot be detected by the tyre pres-
sure loss warning system.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the tyre 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
manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration).
R you are towing a very heavy or large trailer.
R you are driving with a heavy load (in the vehi-
cle or on the roof). Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system if
you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, make sure that the tyre
pressures are set properly on all four tyres for the respective operating conditions. The rec-
ommended tyre pressures can be found in the
tyre pressure table on the fuel filler flap.
The tyre pressure loss warning system can
only give reliable warnings if you have set the correct tyre pressure. If an incorrect tyre
pressure is set, these incorrect values will be
monitored.

The tyre pressure values stored at the last
restart will continue to be monitored. Tyre pressure monitor
General notes If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that moni-
tor the tyre pressures in all four tyres. The tyre
pressure monitor warns you if the pressure
drops in one or more of the tyres. The tyre pres- sure monitor only functions if the corresponding
sensors are fitted to all wheels.
Information on tyre pressures is shown in the
multifunction display. After a few minutes of
driving, the current tyre pressure of each tyre is
shown in the Serv. Serv.menu of the multifunction
display, see illustration (example). For further information on displaying this mes-
sage, refer to the "Checking the tyre pressure
electronically" section (Y page 411).
Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating situation
(Y page 408). Note that the correct tyre pres-
sure for the current operating situation must
first be taught-in to the tyre pressure monitor. If
there is a substantial loss of pressure, the warn- ing threshold for the warning message is aligned
to the reference values taught-in. Restart the
tyre pressure monitor after adjusting to the cold tyre pressure (Y page 412). The current pres-
sures are saved as new reference values. This
will ensure that a warning message will only
appear if the tyre pressure drops significantly.
The tyre pressure monitor does not warn you of
an incorrectly set tyre pressure. Observe the
notes on the recommended tyre pressure
(Y page 408). The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the tyre
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
manoeuvres.
The tyre pressure monitor has a yellow warning
lamp in the instrument cluster for indicating a
pressure loss or malfunction. Depending on how
the warning lamp flashes or lights up, a tyre
pressure that is too low or a malfunction in the
tyre pressure monitor is indicated:
R if the warning lamp is lit continuously, the tyre
pressure on one or more tyres is significantly
too low. The tyre pressure monitor is not mal- functioning.
R if the warning lamp flashes for around a
minute and then remains lit constantly, the
tyre pressure monitor is malfunctioning.
In addition to the warning lamp, a message
appears in the multifunction display. Observe
the information on display messages
(Y page 330).
It may take up to ten minutes for a malfunction
of the tyre pressure monitor to be indicated. A
malfunction will be indicated by the tyre pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
fault has been rectified, the tyre pressure warn- ing lamp goes out after you have driven for a few
minutes.
The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at a filling station using a pressure gauge.
The tyre pressures shown by the on-board com- puter refer to those measured at sea level. At
high altitudes, the tyre pressure values indica-
ted by a pressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tyre pressures.
The operation of the tyre pressure monitor can
be affected by interference from radio transmit-
ting equipment (e.g. radio headphones, two-way radios) that may be being operated in or near the vehicle.

If the wheel positions on the vehicle are inter-
changed, the tyre pressures may be displayed
for the wrong positions for a short time. After a
few minutes of driving, this is rectified and the
tyre pressures are displayed for the correct
positions. Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tyre pressures as the reference values
for monitoring. In most cases, the tyre pressure monitor will automatically detect the new refer- ence values after you have changed the tyre
pressure. However, you can also set reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values.

Tyre pressureWheels and tyres

You should regularly check the pressure of the
emergency spare wheel, particularly prior to
long trips, and correct the pressure as neces-
sary (Y page 408). The value on the wheel or as
given in the "Wheels and tyres" section is valid
(Y page 432).
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed lim-
itation specified on the emergency spare wheel.
Replace the tyres after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
i If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning
system or the tyre pressure monitor cannot
function reliably. Only restart the tyre pres-
sure loss warning system or tyre pressure
monitor when the defective wheel has been
replaced with a new wheel.
Vehicles with tyre pressure monitor: after
fitting an emergency spare wheel, the system
may still display the tyre pressure of the
removed wheel for a few minutes. The value
displayed for the position where the emer-
gency spare wheel is fitted is not the same as the current tyre pressure of the emergency
spare wheel. Removing/stowing the emergency
