Low tire pressure message
The yellow warning lamp lights up. A
Check Control message is displayed.
▷There is a flat tire or a major loss in
tire inflation pressure.
▷A reset of the system was not carried out
after a wheel was changed. The system
therefore issues a warning based on the tire
pressures before the last reset.
1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.
2.Check whether the vehicle is fitted with
normal tires or run-flat tires.
Run-flat tires, refer to page 188, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.

WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-flat
tires can maintain limited stability. There is risk
of an accident. Do not continue driving if the
vehicle is not equipped with run-flat tires. Ob‐
serve the hints on run-flat tires and continued
driving with these tires.◀
A low tire inflation pressure might turn on DSC
Dynamic Stability Control.
Actions in the event of a flat tire
Normal tires
1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
The tire pressure gauge of the Mobility Sys‐
tem, refer to page 189, can be used for this
purpose.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been initialized. In this case, initialize
the system.
If identification of flat tire damage is not
possible, please contact a dealer’s service
center or another qualified service center or
repair shop.
2.Fix the flat tire using the Mobility System,
refer to page 189.
Use of tire sealant, e.g., the Mobility System,
may damage the TPM wheel electronics. In this
case, have the electronics checked at the next
opportunity and have them replaced if needed.
Run-flat tires
Maximum speed
You may continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.
2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four tires is
shown to be correct, it is possible that the
Tire Pressure Monitor did not perform a re‐
set. Then perform the reset.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on cargo load, driv‐
ing style and road conditions.
A vehicle with an average load has a possible
driving range of approx. 50 miles/80 km.
A vehicle with a damaged tire reacts differently,
e.g., it has reduced lane stability during brak‐
ing, a longer braking distance and different
self-steering properties. Adjust your driving
style accordingly. Avoid abrupt steering ma‐
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be shorter or longer de‐
pending on the driving speed, road conditions,
external temperature, cargo load, etc.
WARNING
Your vehicle handles differently when a
run-flat tire is damaged and has low or missing
tire inflation pressure, for example, your lane
stability is reduced when braking, braking dis‐
tances are longer and the self-steering proper‐
ties will change. There is risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h.◀

When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if needed.
System limits
A natural, even tire inflation pressure loss in all
four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.
Sudden serious tire damage caused by external
circumstances cannot be recognized in ad‐
vance.
The system could be delayed or malfunction in
the following situations:
▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.
▷Sporty driving style: spinning traction
wheels, high lateral acceleration (drifting).
▷When driving with snow chains.Actions in the event of a flat tire

Final tire failure
Vibrations or loud noises while driving can indi‐
cate the final failure of a tire.
Reduce speed and stop; otherwise, pieces of
the tire could come loose and cause an acci‐
dent.
Do not continue driving. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Intelligent Safety

WARNING
Indicators and warnings do not relieve
from the personal responsibility. Due to system
limits, warnings or reactions of the system may
not be output or they may be output too late or
incorrectly. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations.◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing

WARNING
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.◀
RSC – Run-flat tires
Run-flat tires, refer to page 188, are labeled
with a circular symbol containing the letters
RSC marked on the sidewall.
M+S
Winter and all-season tires with better cold
weather performance than summer tires.
Tire tread
Summer tires
Do not drive with a tire tread depth of less than
0.12 inches/3 mm.
There is an increased danger of hydroplaning if
the tread depth is less than 0.12 inches/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 inches/4 mm.
Below a tread depth of 0.16 inches/4 mm, tires
are less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the tire's
circumference and have the legally required
minimum height of 0.063 inches/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
General information
Inspect your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Information
Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles can
cause serious damage to wheels, tires and sus‐
pension parts. This is more likely to occur with
low-profile tires, which provide less cushioning
between the wheel and the road. Be careful to
avoid road hazards and reduce your speed, es‐
pecially if your vehicle is equipped with low-
profile tires.
Indications of tire damage or other vehicle mal‐
functions:
▷Unusual vibrations while driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
Damage can, e. g., be caused by driving over
curbs, road damage, or similar things.

Winter tires
Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires provide
better winter traction than summer tires, they
do not provide the same level of performance
as winter tires.
Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then a respective symbol is displayed in your
field of vision. The label is available from a
dealer’s service center or another qualified
service center or repair shop.
With mounted winter tires, observe and adhere
to the permissible maximum speed.
Run-flat tires
If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in the
case of a flat tire. Further information is availa‐
ble from a dealer’s service center or another
qualified service center or repair shop.
Rotating wheels between axles
Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated between
the axles to achieve even wear. Further infor‐
mation is available from a dealer’s service cen‐
ter or another qualified service center or repair
shop. After rotating, check the tire pressure and
correct if needed.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Run-flat tires
Label
RSC label on the tire sidewall.
The wheels are composed of tires that are self-
supporting to a limited degree.
The support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the
event of a tire inflation pressure loss.
Continued driving with a damaged tire, refer to
page 109.
Continued driving with a damaged tire, refer to
page 106.
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
A dealer’s service center will be glad to answer
additional questions at any time.
Repairing a flat tire
Safety measures
▷Park the vehicle as far away as possible
from passing traffic and on solid ground.
▷Switch on the hazard warning system.▷Secure the vehicle against rolling away by
setting the parking brake.
▷Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.
Seite 188MOBILITYWheels and tires188
Online Edition for Part no. 01 40 2 964 571 - X/15
▷Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.
▷If necessary, set up a warning triangle at an
appropriate distance.
Mobility System
The concept
With the Mobility System, minor tire damage
can be sealed temporarily to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the
inside.
The compressor can be used to check the tire
inflation pressure.
Information
▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.
▷Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 inches/4 mm or more.
▷Contact a dealer’s service center or another
qualified service center or repair shop if the
tire cannot be made drivable.
▷If possible, do not remove foreign bodies
that have penetrated the tire.
▷Pull the speed limit sticker off the sealant
container and apply it to the steering
wheel.
▷The use of a sealant can damage the TPM
wheel electronics. In this case, have the
electronics checked at the next opportunity
and have them replaced if needed.
DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of the
vehicle. There is danger to life. Keep the ex‐
haust pipe free and ensure sufficient ventila‐
tion.◀
Storage
The Mobility System is in a bag in the front left
of the trunk.

5.With the compressor switched off, insert
the plug into the power socket inside the
vehicle.
6.With operating readiness switched on or
the engine running, switch on the compres‐
sor.
Let the compressor run for max. 10 minutes to
fill the tire with sealant and achieve a tire infla‐
tion pressure of approx. 2.5 bar.
While the tire is being filled with sealant, the
tire inflation pressure may sporadically reach
approx. 5 bar. Do not switch off the compressor
at this point.
