Do not continue driving. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Required tire inflation pressure check
message
A Check Control message is displayed in the
following situations▷The system has detected a wheel change,
but no reset was done.▷Inflation was not carried out according to
specifications.▷The tire inflation pressure has fallen below
the level of the last confirmation.
In this case:
▷Check the tire pressure and correct as
needed.▷Carry out a reset of the system after a tire
change.
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 and
then 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: Have it checked by a dealer’s
service center or another 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
Seite 109SafetyControls109
Online Edition for Part no. 01 40 2 964 144 - VI/15
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 conceptThe system detects tire inflation pressure losson 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.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.1."Vehicle info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"
The status is displayed.
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.
On the Control Display:
1."Vehicle info"2."Vehicle status"3. "Perform reset"4.Start the engine - do not drive off.5.Start the initialization with "Perform reset".6.Drive away.
The initialization is completed while driving,
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.Seite 110ControlsSafety110
Online Edition for Part no. 01 40 2 964 144 - VI/15
Run-flat tires, refer to page 202, 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.
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.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.Rectify the flat tire on the damaged wheel.
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.

Online Edition for Part no. 01 40 2 964 144 - VI/15
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.
Intelligent Safety The concept
Intelligent Safety enables central operation of
the driver assistance system. Depending on
how the vehicle is equipped, Intelligent Safety
consists of one or more systems that can help
prevent a imminent collision.▷Front-end collision warning, refer to
page 113.▷Pedestrian warning, refer to page 119.▷Lane departure warning, refer to
page 121.▷Active Blind Spot Detection, refer to
page 123.
Information
WARNING
Indicators and warnings do not relieve
from the personal responsibility. Due to sys‐
tem 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 condi‐
tions. Watch traffic closely and actively inter‐
fere in the respective situations.◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated,
e.g. approach control warning with light brak‐
ing function. There is risk of an accident.
Switch all Intelligent Safety systems off prior to
tow-starting/towing.◀

ServotronicThe concept
The Servotronic varies the steering force re‐
quired to turn the wheels in accordance with
the vehicle speed. At low speeds, the steering
force is strongly supported, i. e. during steer‐
ing, low force is required. As the speed in‐
creases, the assistance of the steering force is
reduced.
Furthermore, the steering force adapts accord‐
ing to the driving program, so that a direct,
sporty feel and/or comfortable steering is con‐
veyed.
Driving Dynamics Control The conceptThe Driving Dynamics Control helps to fine-
tune the vehicle's settings and features. Vari‐
ous programs can be selected for this purpose.
The Driving Dynamics Control and the DSC

The car's interior can only be cooled with the
engine running.
Press button.
The air will be cooled and dehumidi‐
fied and, depending on the temperature set‐
ting, warmed again.
Depending on the weather, the windshield and
side windows may fog up briefly when the en‐
gine is started.

ops that exits underneath the vehicle.
AUTO program Press button.
Air flow, air distribution and tempera‐
ture are controlled automatically.
Depending on the selected temperature and
outside influences, the air is directed to the
windshield, side windows, upper body, and
into the footwell.
The cooling function, refer to page 156, is
switched on automatically with the AUTO pro‐
gram.
Recirculated-air mode You may respond to unpleasant odors or pollu‐
tants in the immediate environment by tempo‐
rarily suspending the supply of outside air. The
system then recirculates the air currently
within the vehicle.
Press button repeatedly to select an
operating mode:▷LED off: outside air flows in continuously.▷LED on, recirculated-air mode: the supply
of outside air into the vehicle is perma‐
nently blocked.
Recirculated air mode switches off automati‐
cally at low external temperatures after a cer‐
tain amount of time in order to avoid window
fogging.
With constant recirculated-air mode, the air
quality in the car's interior deteriorates and the
fogging of the windows increases.
If the windows fog over, switch off recircu‐
lated-air mode and increase the air flow, if
needed.

Things to remember when drivingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Breaking-in period General information
Moving parts need time to adjust to one an‐
other (break-in time).
The following instructions will help accomplish
a long vehicle life and good efficiency.
During break-in, do not use the Launch Con‐
trol, refer to page 80.
Engine, transmission, and axle drive
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:▷For gasoline engine 4,500 rpm and
100 mph/160 km/h.
Avoid full load or kickdown under all circum‐
stances.
From 1,200 miles/2,000 km The engine and vehicle speed can gradually be
increased.
Tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
Drive conservatively for the first
200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimal per‐
formance between brake discs and brake
pads. Drive moderately during this break-in pe‐
riod.
Following part replacement
The same break-in procedures should be ob‐
served if any of the components above-men‐
tioned have to be renewed in the course of the
vehicle's operating life.
Driving on poor roads
The vehicle combines all-wheel drive with the
advantages of a normal automobile.
CAUTION
Objects in unpaved areas, e.g. stones or
branches, can damage the vehicle. There is
risk of property damage. Do not drive on un‐
paved terrain.◀
For your own safety, for the safety of passen‐
gers and of the vehicle, heed the following
points:▷Become familiar with the vehicle before
starting a trip; do not take risks in driving.▷Adjust the speed to the road surface con‐
ditions. The steeper and more uneven the
road surface, the slower the speed should
be.▷When driving on steep uphill or downhill
grades: add engine oil and coolant up to
near the MAX mark. Uphill and downhillSeite 176Driving tipsThings to remember when driving176
Online Edition for Part no. 01 40 2 964 144 - VI/15
grades can be traveled up to no more than
50 %.▷On steep downhill grades, use Hill Descent
Control HDC, refer to page 128.
Starting out is possible on uphill grades up
to 30 %. The permissible side tilt is 30 %.▷Avoid that the chassis bottom coming in
contact with the ground.
The ground clearance is no more than 7.8
inches/20 cm and can vary according to
the vehicle's load.▷When wheels continue to spin, depress the
accelerator so that driving stability control
systems can distribute the driving force to
the wheels. Activate DTC Dynamic Trac‐
tion Control if available.
After a trip on poor roads
After a trip on poor roads, check wheels and
tires for damage to maintain driving safety.
Clear heavy soiling from the body.
General driving notes
Closing the tailgate WARNING
An open tailgate protrudes from the vehi‐
cle and can endanger occupants and other
traffic participants or damage the vehicle in the
event of an accident, braking or evasive ma‐
neuvers. In addition, exhaust fumes may enter
the vehicle interior. There is risk of injuries or
risk of property damage. Do not drive with the
tailgate open.◀
If driving with the tailgate open cannot be
avoided:
▷Close all windows and the glass sunroof.▷Greatly increase the air flow from the vents.▷Drive moderately.Hot exhaust system
WARNING
During driving operation, high tempera‐
tures can occur underneath the body, e.g.
caused by the exhaust gas system. If combus‐
tible materials, such as leaves or grass, come
in contact with hot parts of the exhaust gas
system, these materials can ignite. There is
risk of injuries or risk of property damage.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that no combustible materials can come in
contact with hot vehicle parts in driving opera‐
tion, idle or during parking. Do not touch the
hot exhaust system.◀
Mobile communication devices in the
vehicle
WARNING
Vehicle electronics and mobile phones
can influence one another. There is radiation
due to the send operations of mobile phones.
There is risk of injuries or risk of property dam‐
age. If possible, in the car's interior use only
mobile phones with direct connections to an
exterior antenna in order to exclude mutual
disturbance and deflect the radiation from the
car's interior.◀
Hydroplaning
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Driving through water CAUTION
When driving too quickly through too
deep water, water can enter into the engine
compartment, the electrical system or theSeite 177Things to remember when drivingDriving tips177
