Sitting safely
The ideal sitting position can make a vital con-
tribution to relaxed driving that is as fatigue-free
as possible. Together with safety belts, head
restraints, and airbags, sitting position plays an
important role in an accident. Compliance with
the following instructions is important; failure to
do so could impair the protective function of the
safety systems.
For additional information on transporting chil-
dren safely, refer to page33.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
hold the steering wheel by its rim with hands at
the 9 o'clock and 3 o'clock positions, to mini-
mize the risk of injuries to your hands and arms
in the event of airbag deployment.
No one and nothing is to come between the air-
bags and the seat occupant.
Do not use the cover of the front airbag on the
front passenger side as a storage area. Make
sure that the passenger sits correctly, e.g. does
not rest his feet or legs on the dashboard. Oth-
erwise, a triggering of the front airbag could
result in leg injuries. Make sure that passengers
do not lean their heads against side or head air-
bags. Otherwise, a triggering of the airbag could
result in injuries.<
Even if you adhere to all the instructions, inju-
ries resulting from contact with airbags cannot
be entirely ruled out, depending on the circum-
stances. The ignition and inflation noise may
provoke a mild – usually temporary – hearing
loss in extremely sensitive individuals.
For airbag locations and additional information
on airbags, refer to page53.
Head restraint
A correctly adjusted head restraint reduces the
risk of damage to the cervical vertebrae in acci-
dents.
Adjust the head restraint so that its mid-
dle lies approximately at the height of
your ears. Otherwise, there is an increased risk
of injury in the event of an accident.<
Safety belts
Make sure the safety belts are worn in all occu-
pied seats every time you drive. Although air-
bags enhance safety by providing added pro-
tection, they are not a substitute for safety
belts.
Your vehicle has five seats that are each
equipped with a safety belt.
Never allow more than one person to
wear a single safety belt. Infants and chil-
dren must not ride on a lap. Make sure that the
belt in the lap area sits low against the hips and
does not press against the abdomen. The
safety belt must never rest against the throat,
rub against sharp edges, pass over hard o r frag-
ile objects or be pinched. Fasten the safety belt
around your body snugly, making sure that it is
pulled taut across your lap and shoulder and
that it is not twisted; otherwise, the belt can
slide over the hips in the event of a frontal colli-
sion and injure your abdomen. Avoid wearing
clothing that prevents the belt from fitting prop-
erly and pull the shoulder belt upward periodi-
cally to readjust the tension across your lap in
order to avoid a reduction in the restraining
action of the safety belt.<
If the middle safety belt in the rear is used, then
the wider backrest must be secured, refer to
page70, otherwise, the safety belt cannot exert
any restraining action.
Safety belts, refer to page29.

Activating system
Press the button; the LED lights up.
The LED flashes when the brakes are applied
automatically.
Deactivating system
Press the button again; the LED goes out.
HDC is deactivated immediately above approx.
35 mph/60 km/h and after approx. 10 seconds
when the ignition is switched off.
Using HDC
With manual transmission:
Use HDC in first gear and in reverse, because in
the higher gears the engine's braking action
diminishes.
With automatic transmission:
You can use HDC in every drive position.
Malfunction
If the LED in the button goes out in the HDC
mode or fails to light up when the button is
pressed:
HDC is temporarily not available, because the
brake temperature is too high.
Malfunction in vehicle stability control
systems
The warning lamp lights up yellow. DBC
Dynamic Brake Control is malfunction-
ing. Have the system checked as soon
as possible.
Display of the previously described mal-
function on Canadian models.If one of the malfunctions described
below occurs, proceed cautiously and
defensively. When driving on poor roads, avoid
using the full throttle or kick-down positions of
the accelerator as well as heavy and panic brak-
ing. Otherwise, the drive train may be damaged
or accidents can occur.<
The red brake warning lamp lights up
together with the warning lamps for
ABS and DSC/xDrive. In addition, a
warning signal sounds. ABS, DSC, HDC
and xDrive have failed. It is then possi-
ble to exert driving force only via the
rear axle. If the brake warning lamp
lights up yellow in the described combi-
nation, the EBV Electronic brake-force distribu-
tion is still available. Have the system checked
as soon as possible.
Display of the previously described mal-
function on Canadian models.
The warning lamp lights up continu-
ously and a warning signal sounds:
DSC or the xDrive all-wheel system has
failed.
The stabilizing interventions of DSC or the all-
wheel drive system xDrive are no longer avail-
able. It is then possible to exert driving force
only via the rear axle. Have the system checked
as soon as possible.
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system triggers an alert whenever
the inflation pressure in one tire drops signifi-
cantly in relation to the pressure in another tire.
When a loss of pressure occurs, the rolling
radius changes and with it, the rotational speed

of the wheels. This change is detected and sig-
naled as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure, after every tire or wheel change, and after
a trailer is hitched or unhitched.<
System limits
The Flat Tire Monitor cannot predict sud-
den severe tire damage caused by out-
side factors and does not detect a natural, even
pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>When the system has not been initialized
>When driving on snow-covered or slippery
road surfaces
>Sporty driving style: slip in the drive wheels,
high lateral acceleration.
>When driving with snow chains
When driving with a compact wheel, the Flat
Tire Monitor cannot operate.
Initializing system
The system must be reinitialized after
every correction of tire inflation pressure
and after every tire or wheel change. Do not ini-
tialize the system when driving with snow
chains or with a compact wheel.<
1.Start the engine just before driving, but do
not begin to drive.
2.Press the button for at least 4 seconds, but
not longer than 2 minutes. After the button
is released, the indicator lamp in the instru-
ment cluster lights up yellow for a few sec-
onds.3.Begin driving.
The initialization is completed during driv-
ing and can be interrupted at any time with-
out requiring any input from you. The initial-
ization automatically continues when
driving resumes.
Indication of a flat tire
The warning lamp lights up red. In addi-
tion, an acoustic signal sounds. There is
a flat tire or extensive inflation pressure
loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire.
If identification is not possible, con-
tact your BMW Sports Activity Vehi-
cle Center.<
3.Replace the damaged wheel, refer to
Changing a wheel on page103.
Malfunction
The warning lamp lights up yellow. The
Flat Tire Monitor is malfunctioning or
out of order. Have the system checked
as soon as possible.

TPM Tire Pressure Monitor*
The concept
TPM controls the tire inflation pressure in the
four mounted wheels. The system notifies you
if the tire inflation pressure has fallen signifi-
cantly in one or more tires.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be reset at the correct tire inflation
pressure.
Always use wheels equipped with TPM elec-
tronics, including a metal valve; otherwise, there
is no guarantee that the system will function
properly.
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot warn you of sudden, serious
tire damage due to external factors.<
The system does not function properly if it has
not been reset, e.g. it may identify a tire as flat in
spite of the fact that the tire is filled to the cor-
rect inflation pressure.
The system is inactive and cannot indicate flat
tires if a wheel not equipped with TPM electron-
ics has been mounted, e.g. a compact wheel, or
if TPM is experiencing temporary interference
from other systems or devices that use the
same frequency.
Resetting system
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.<1.Start engine, but do not begin to drive.
2.Press the button until the yellow warning
lamp in the instrument cluster lights up for a
few seconds.
3.Begin driving.
After a few minutes of driving, the tire infla-
tion pressures in the tires are adopted as
the desired values to be monitored. The
resetting is completed during driving and
can be interrupted at any time without
requiring any input from you. The resetting
automatically continues when driving
resumes.
Low tire pressure message
The warning lamp lights up yellow. In
addition, a signal sounds. You have a
flat tire or a significant loss of tire pres-
sure in one or more tires.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify the damaged wheel or wheels.
If identification is not possible, con-
tact your BMW Sports Activity Vehi-
cle Center.<
3.Replace the damaged wheel, refer to
Wheel changes on page103.
4.Check tire inflation pressure and correct as
needed.
The compact wheel is not equipped with the
required TPM electronics and is not monitored
when mounted.
When driving with the compact wheel, the sys-
tem indicates a malfunction.

Have the damaged tire replaced by your BMW
Sports Activity Vehicle Center or a workshop
that is familiar with TPM and works in accor-
dance with BMW repair procedures, using
appropriately trained personnel.
Malfunction
The yellow warning lamp flashes and
then lights up continuously. Flat tires
cannot be detected.
Such a message is displayed in the following
situations:
>In the event of a malfunction:
Have the system checked
>When a wheel without TPM electronics is
mounted, e.g. a compact wheel
>When TPM is experiencing temporary inter-
ference from other systems or devices that
use the same frequency
Brake force display
The brake lamps light up in two stages,
depending on how heavily you apply the brakes.
>Normal braking:
The brake lamps 1 and the center brake
lamp light up.
>Powerful braking:
The brake lamps 1 and 2 light up together
with the center brake lamp.
Airbags
The following airbags are located beneath the
marked covers:
1Front airbags
2Head airbags
3Side airbags in front and rear
*
Protective action
To ensure that the safety systems con-
tinue to provide optimal protection,
please follow the instructions on page26.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
respective head airbag supports the head.
The airbags will purposely not be activated by
every collision, e.g. not by more minor acci-
dents, or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Do not attempt to remove the airbag retention
system from the vehicle. Do not modify the indi-
vidual components of the system or its wiring in
any way. This includes the padded covers in the
center of the steering wheel, on the dashboard,
the doors, and the roof pillars as well as the
sides of the headliner. Do not attempt to
remove or dismantle the steering wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns.

Wheels and tires
Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check tire inflation pressure when the tires
are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly
and correct it as needed, even on the
compact wheel: at least twice a month and
before starting long trips. If you fail to observe
this precaution, you may be driving on tires with
incorrect tire pressures, a condition that can not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.
Do not drive with deflated, i.e. flat tires. A flat tire
will seriously impair your vehicle's handling and
braking response. Attempts to drive on a flat tire
can lead to loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to pages51,
52.<
Pressure specifications
The table on the next page provides all the cor-
rect inflation pressures for the specified tire
sizes at ambient temperature.
The inflation pressures in the table apply
to BMW-approved tire sizes and recom-
mended tire brands. Your BMW Sports Activity
Vehicle Center will be glad to supply this infor-
mation. tion pressure for your tires, please note the fol-
lowing:
>Tire size for your vehicle
>Load status
>Maximum permissible driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving at speeds of up to 100 mph/
160 km/h and to achieve an optimal driving
comfort, take note of the tire inflation pressures
listed on the following page in the column for
speeds up to max. 100 mph/160 km/h and
adjust your tire pressure as needed.
These tire inflation pressures are also listed on
the door pillar and can be seen with the driver's
door open.
The maximum permissible speed for
these tire inflation pressures is 100 mph/
160 km/h. Do not exceed this speed; failure to
heed this limit can lead to tire damage and acci-
dents.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds
above 100 mph/160 km/h, take note of
the tire inflation pressures listed in the column
for speeds above 100 mph/160 km/h in the
table on the following page and adjust your tire
pressure as needed. Failure to due so can lead
to tire damage and accidents.<

Temperature
The temperature grades are A, B, and C, A
being highest, and represent the tire’s resis-
tance to the generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory test
wheel. Sustained 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 corre-
sponds to a level of performance that all pas-
senger car tires must meet under the Federal
Motor Vehicle Safety Standard No. 109. Grades
B and A represent higher levels of performance
on the laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not fall below 0.12 in/
3 mm. At tread depths below 0.12 in/3 mm,
there is an increased risk of high-speed hydro-
planing, even when only small amounts of water
are present on the road surface.
Winter tires display a noticeable loss in their
ability to cope with cold-weather driving condi-
tions once the tread wears to below 0.16 in/
4 mm. To ensure continued safety you should
always have such tires replaced.Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has worn down to the wear indicators, then the
legally permissible tread depth limit of 0.063 in/
1.6 mm has been reached.
Wheel/tire damage
Please note that low-profile tires, make
wheels, tires and suspension parts more
susceptible to road hazard and consequential
damages.<
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immedi-
ately and have wheels and tires checked
immediately. Drive carefully to the nearest
BMW Sports Activity Vehicle Center or tire spe-
cialist. Have the vehicle towed to one of these
locations if necessary.
Tire damage can pose a potentially lethal safety
hazard for the vehicle's occupants and other
road users alike.<
New wheels and tires
Have new wheels and tires installed only
by your BMW Sports Activity Vehicle
Center or a tire shop that works according to
BMW repair procedures with correspondingly
trained personnel. If this work is not carried out
properly, there is a danger of subsequent dam-

Wheels and tires
90 age and related safety hazards. Make sure that
the new wheels are balanced.<
Retreaded tires
BMW does not recommend the use of
retreaded tires; otherwise, driving safety
may be reduced. The causes for this include the
possibly different tire casing structures and the
often wide variations in their age, which can
result in a limited service life.<
The right wheels and tires
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact and with it, the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can ask your BMW Sports Activity Vehicle
Center for the correct wheel-and-tire combina-
tion.
The correct wheel-and-tire combination affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After a flat
tire, always have the original wheel-and-tire
combination remounted on the vehicle as soon
as possible.
Wheels equipped with electronics for
TPM Tire Pressure Monitor
When installing new tires or when changing
from summer tires to winter tires or vice versa,
only use wheels equipped with TPM electron-
ics; otherwise, the Tire Pressure Monitor can-
not detect a flat tire, refer to page52. Your
BMW Sports Activity Vehicle Center will be
happy to advise you in this regard.
Recommended tire brands
BMW recommends particular tire brands for
each tire size. You will recognize them by the
clearly visible BMW identification on the tire
sidewall.
With proper use, these tires meet the highest
standards for safety and handling characteris-
tics.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires do provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.<
Storage
Store wheels or tires in a cool, dry place, pro-
tecting them from light whenever possible. Pro-
tect the tires from contact with oil, grease and
fuel. Do not exceed the maximum tire inflation
pressure indicated on the side wall of the tire.

Snow chains*
Only certain fine-link snow chains are tested,
classified as road-safe, and recommended by
BMW. You can obtain a list of these from your
BMW Sports Activity Vehicle Center. It is only
permissible to use them in pairs and on the rear
wheels.
Follow the manufacturer's instructions when
installing snow chains.
Do not exceed a vehicle speed of 30 mph/
50 km/h with snow chains mounted.
It is not permissible to use snow chains on the
following tire sizes:
>255/45 R 18
>255/40 R 19
Do not initialize the Flat Tire Monitor
*
with snow chains installed; otherwise, the
instrument might issue an incorrect reading.
When you are driving with snow chains, it can
be beneficial to switch off DSC briefly, refer to
page49.<
