Snow chains
Fine-link snow chains The manufacturer of your vehicle recommends
use of fine-link snow chains. Certain types of
fine-link snow chains have been tested by the
manufacturer of the vehicle and recommended
as road-safe and suitable.
Information regarding suitable snow chains is
available from a dealer’s service center or an‐
other qualified service center or repair shop.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:▷245/50 R 18.▷245/45 R 19.
Follow the snow chain manufacturer's instruc‐
tions.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing 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 needed.
Maximum speed with snow chains Do not exceed a speed of 30 mph/50 km/hwhen using snow chains.
Rear wheel steering during operation with snow chains
General information
In order to guarantee free running of the
wheels when operating with snow chains, the
rear wheel steering of the integral active steer‐
ing must be switched off when snow chains
are mounted. For this, it is possible to confirm
via iDrive that snow chains are mounted.
Information WARNING
When rear wheel steering is switched on
and snow chains are mounted, there can be
contact between snow chains and the chassis.
There is risk of accidents or risk of property
damage. With mounted snow chains, switch
off the rear wheel steering.◀
Switching off rear wheel steering With the setting that snow chains are
mounted, the rear wheel steering is switched
off.
About iDrive:1."My Vehicle"2."Vehicle settings"3."Tire chains"4."Tire chains installed"
Starting with the permissible maximum speed
with snow chains of 30 mph/50 km/h the rear
wheel steering will be switched on automati‐
cally.
Tire Pressure Monitor TPM
The concept
The system monitors tire inflation pressure in
the four mounted tires. The system warns you
if there is a loss of pressure in one or more
tires. For this purpose, sensors in the tire
valves measure the tire inflation pressure and
tire temperature.
Information
With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 254.

Functional requirements
The system must have been reset with the
correct tire inflation pressure; otherwise, relia‐
ble signaling of tire inflation pressure loss is
not assured.
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to
ensure that the system will operate properly.

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.
Observe the information 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
System, refer to page 260, can be used for
this purpose.
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 reset. Then perform the reset.Seite 266MobilityWheels and tires266
Online Edition for Part no. 0140 2 964 330 - VI/15

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.Fixing a flat tire, where applicable with the
Mobility System.3.Replacing a damaged tire, where applica‐
ble with the emergency wheel.
Use of 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 reset. In that case, carry out a 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 differ‐
ently, e.g., it has reduced lane stability during
braking, 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 de‐
pends on how the vehicle is used during the
trip, the actual distance may be shorter or lon‐
ger depending on the driving speed, road con‐
ditions, 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, e.g., your lane stability is
reduced when braking, braking distances are
longer and the self-steering properties will
change. There is risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h.◀
System limits
The system does not function properly if a re‐
set has not been carried out, e.g., a flat tire is
reported though tire inflation pressures are
correct.
The tire inflation pressure depends on the
tire's temperature. Driving or exposure to the
sun will increase the tire's temperature, thus
increasing the tire inflation pressure. The tire
inflation pressure is reduced when the tire
temperature falls again. These circumstances
may cause a warning when temperatures fall
very sharply.
The system cannot indicate sudden serious
tire damage caused by external circumstances.
Malfunction The yellow warning lamp flashes andthen lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire inflation pressure can be de‐
tected.
Examples and recommendations in the follow‐
ing situations:▷A wheel without TPM electronics is
mounted, e.g. emergency wheel: Have itSeite 267Wheels and tiresMobility267

checked by a dealer’s service center or an‐
other qualified service center or repair
shop as needed.▷Malfunction: Have system checked by a
dealer’s service center or another qualified
service center or repair shop.▷TPM was unable to complete the reset.
Reset the system again.▷Interference through systems or devices
with the same radio frequency: After leav‐
ing the area of the interference, the system
automatically becomes active again.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency and tire tread life, and may affect the
vehicle's handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the
level to trigger illumination of the TPMS low
tire pressure telltale. Your vehicle has also
been equipped with a TPMS malfunction indi‐
cator to indicate when the system is not oper‐
ating properly. The TPMS malfunction indica‐
tor is combined with the low tire pressure
telltale. When the system detects a malfunc‐
tion, the telltale will flash for approximately one
minute and then remain continuously illumi‐
nated. This sequence will continue upon sub‐
sequent vehicle start-ups as long as the mal‐
function exists. When the malfunction indicator
is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace‐
ment or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning prop‐
erly. Always check the TPMS malfunction tell‐
tale after replacing one or more tires or wheels
on your vehicle to ensure that the replacement
or alternate tires and wheels allow the TPMS
to continue to function properly.
FTM Flat Tire Monitor
The concept The system detects tire inflation pressure loss
on the basis of rotation speed differences be‐
tween the individual wheels while driving.
In the event of a tire inflation pressure loss, the
diameter and therefore the rotational speed of
the corresponding wheel changes. This will be
detected and reported as a flat tire.
The system does not measure the actual infla‐
tion pressure in the tires.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable flagging of a flat tire is not as‐
sured. Initialize the system after each correc‐
tion of the tire inflation pressure and after
every tire or wheel change.Seite 268MobilityWheels and tires268

Initialization
When initializing the once set inflation tire
pressures serve as reference values in order to
detect a flat tire. Initialization is started by con‐
firming the tire inflation pressures.
Do not initialize the system when driving with
snow chains.

which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Indication of a flat tire 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.
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 260, 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.
Observe the information on run-flat tires and
continued driving with these tires.◀
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 exter‐
nal 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
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
System, refer to page 260, can be used for
this purpose.
If the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor may notSeite 269Wheels and tiresMobility269

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 260.
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 correct, the Flat Tire 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 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 differ‐
ently, e.g., it has reduced lane stability during
braking, 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 de‐
pends on how the vehicle is used during the
trip, the actual distance may be shorter or lon‐
ger depending on the driving speed, road con‐
ditions, 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, e.g., your lane stability is
reduced when braking, braking distances are
longer and the self-steering properties will
change. There is risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h.◀
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.Seite 270MobilityWheels and tires270

Lights and bulbs
General information
Lights and bulbs make an essential contribu‐
tion to vehicle safety.
All headlights and lights are made using LED
or laser technology.
The vehicle manufacturer recommends that
you let a dealer’s service center or another
qualified service center or repair shop perform
the work in case of a malfunction.
Information
Lights and bulbs DANGER
There can be high voltage in the lighting
system. There is danger to life. The manufac‐
turer of your vehicle recommends that the
work on the lighting system including bulb re‐
placement be performed by a dealer’s service
center or another qualified service center or re‐
pair shop.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated
as Class 1 light-emitting diodes.
WARNING
Too intensive brightness can irritate or
damage the retina of the eye. There is risk of
injuries. Do not look directly into the headlights
or other light sources for an extended period of
time. Do not remove the LED covers.◀
Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the lights switched on, the con‐densation evaporates after a short time. The
headlight glass does not need to be changed.
If despite driving with the lights switched on,
increasing humidity forms, e. g. water droplets
in the lamp, the manufacturer of your vehicle
recommends having it checked by a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Changing wheels
Information When using run-flat tires or sealants, a tire
does not need to be changed immediately in
the event of pressure loss due to a flat tire.
The tools for changing wheels are available as
accessories from your dealer’s service center
or another qualified service center or repair
shop.
