The system cannot detect a flat tire. Reasons for
this may be:
▷TPM is being reset.▷Disturbance by systems or devices with the
same radio frequency.▷Malfunction.
For Canadian models: additional
information
The status display additionally shows the cur‐
rent tire inflation pressures and tire tempera‐
tures.
When correcting the tire inflation pressures,
note the following:
The tire pressure increases as the tire temper‐
ature increases.
Therefore, only correct the tire inflation pres‐
sure when the tire is at the ambient temperature.
Compare the displayed tire temperature with
the external temperature in the instrument clus‐
ter.

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.
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 an identification is not possible, please
contact the service center.2.Rectify the flat tire.
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 re‐
placed if necessary.
Run-flat tires
Maximum speed
You can 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
correct, the Tire Pressure Monitor may not
have been initialized. In this case, initialize
the system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx. 50 miles/
80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing 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 smaller or greater de‐
pending on the driving speed, road conditions,
external temperature, cargo load, etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering prop‐
erties.◀
Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could
come loose and cause an accident. Do not con‐
tinue driving, and contact your service center. ◀

In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirements
The system must have been initialized when the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires can‐
not be detected. Therefore, check the tire infla‐
tion pressure regularly.
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: slip in the drive wheels,
high lateral acceleration.▷When driving with snow chains.
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.

Initialization
The initialization process adopts the set inflation
tire pressures as reference values for the detec‐
tion of a flat tire. Initialization is started by con‐
firming the inflation pressures.

Lane departure warning
The concept
This system issues a warning at speeds above
approx. 40 mph/65 km/h if the vehicle is about
to leave the lane on roads with lane markings.
The steering wheel begins vibrating gently. The
time of the warning may vary depending on the
current driving situation.
The system does not provide a warning if the
turn signal is set before leaving the lane.

LoadingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
General information Overloading the vehicle
To avoid exceeding the approved carrying
capacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden loss
of tire inflation pressure.◀
No fluids in the trunk
Make sure that fluids do not leak into the
trunk; otherwise, the vehicle may be damaged. ◀
Determining the load limit1.Locate the following statement on your ve‐
hicle’s placard:▷The combined weight of occupants and
cargo should never exceed XXX kg or
YYY lbs. Otherwise, damage to the ve‐hicle and unstable driving situations may
result.2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.3.Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs pas‐
sengers in your vehicle, the amount of avail‐
able cargo and luggage load capacity is
400 lbs: 1,000 lbs minus 600 lbs = 400 lbs.5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
Load
The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.

under controlled conditions on a specified gov‐
ernment test course. For example, a tire graded
150 would wear one and one-half, 1 g, times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, however,
and may depart significantly from the norm due
to variations in driving habits, service practices
and differences in road characteristics and cli‐
mate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfa‐
ces of asphalt and concrete. A tire marked C may
have poor traction performance.
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and
does not include acceleration, cornering, hydro‐
planing, or peak traction characteristics.
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sus‐
tained high temperature can cause the material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades Band A represent
higher levels of performance on the laboratory
test wheel than the minimum required by law.
Temperature grade for this tire
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 incombination, can cause heat buildup and pos‐
sible tire failure.
If necessary, have the vehicle towed.◀
RSC – Run-flat tires
Run-flat tires, refer to page 280, 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 in/3 mm.
There is an increased danger of hydroplaning if
the tread depth is less than 0.12 in/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Below a tread depth of 0.16 in/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 in/1.6 mm.
They are marked on the side of the tire with TWI,
Tread Wear Indicator.

Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
With proper use, these tires meet the highest
standards for safety and handling.
New tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac‐
tion potential until after an initial breaking-in pe‐
riod.
Drive conservatively for the first 200 miles/
300 km.
Retreaded tires
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
Winter tires
The manufacturer of your vehicle recommends
winter tires for winter roads or at temperatures
below +45 ℉/+7 ℃.
Although so-called all-season M+S tires do pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance 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 display a corresponding sign in the field of
vision. You can obtain this sign from the tire spe‐
cialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for the
winter tires; otherwise, tire damage and acci‐
dents can occur.◀
Run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire. Your
service center will be glad to advise you.
Rotating wheels between axles
The manufacturer of your vehicle advises
against swapping wheels between the front and
rear axles.
This can impair the handling characteristics.
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.Seite 279Wheels and tiresMobility279

Run-flat tires
Label
RSC label on the tire sidewall.
The wheels are composed of special rims and
tires that are self-supporting, to a limited de‐
gree.
The support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the event
of a pressure loss.
Continued driving with a damaged tire, refer to
page 102.
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. Your
service center will be glad to advise you.
Snow chains
Fine-link snow chains
Only certain types of fine-link snow chains have
been tested by the manufacturer of your vehicle,
classified as road-safe and recommended.
Consult your service center for more informa‐
tion.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:
▷225/55 R 17.▷245/45 R 18.Follow the chain manufacturer's instructions.
Make sure that the snow chains are always suf‐
ficiently tight. Retighten as needed according to
the chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control if necessary.
Maximum speed with snow chains
Do not exceed a speed of 30 mph/50 km/h when
using snow chains.
Snow chain detection
The concept
When using snow chains, you should set
whether you are driving with or without snow
chains via the iDrive.
The snow chain detection system supports you
by automatically showing the detected state on
the Control Display.
When snow chains are in use, the rear axle steer‐
ing of the Integral Active Steering is deactivated
automatically.
At speeds above the maximum allowable speed
with snow chains of 30 mph/50 km/h, the rear
axle steering is activated again automatically.
