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.

Technology for comfort, convenience and safety
54 In the event of malfunctions, deactivation, or
triggering of the airbag restraint system, have
the testing, repair, removal, and disposal of air-
bag generators executed only by a BMW Sports
Activity Vehicle Center or a workshop that
works according to BMW repair procedures
with correspondingly trained personnel and has
the required explosives licenses. Unprofes-
sional attempts to service the system could
lead to failure in an emergency or undesired air-
bag activation, either of which could result in
personal injury.<
Airbag warnings and information are also pro-
vided on the sun visors.
Automatic deactivation of front
passenger airbags
By evaluating the pressure on the seat cushion
of the front passenger seat, the system detects
whether or not the seat is occupied. The front
and side airbags for the passenger are activated
or deactivated by the system accordingly.
The indicator lamp located above the
inside rearview mirror indicates whether
the front passenger airbag system is currently
deactivated or activated, refer to Status of pas-
senger airbag in the section below.<
Before transporting a child in the front
passenger seat, follow the safety notices
and instructions under Transporting children
safely, refer to page33.
When teenagers or adults assume certain sit-
ting positions, the front and side airbags on the
passenger side can deactivate; this causes the
indicator lamp for the front passenger airbag to
light up. If this happens, have them change their
sitting position so that the passenger airbag is
activated and the indicator lamp goes out. If the
desired status cannot be achieved by changing
their sitting position, then have the person ride
in the back. Do not attach seat covers, seat
cushion padding, ball mats or other items to the
passenger seat unless they are specifically rec-
ommended by BMW. Do not place any items
under the seat which could press against the
seat from below. Otherwise, a correct analysis
of the seat cushion is not ensured.<
Status of passenger airbags
The indicator lamp for the passenger airbag
indicates the operational readiness of the front
and side airbag on the passenger side depend-
ing on whether or not the seat is occupied. The
indicator lamp indicates whether the passenger
airbags are activated or deactivated.
>The indicator lamp lights up when a child
sitting as directed in a child restraint system
designed for this is detected.
The front and side airbags on the passenger
side are not activated.
>The indicator lamp does not come on as
long as a person of sufficient size and in a
correct sitting position is detected on the
seat. The front and side airbags for the pas-
senger are activated.
>The indicator lamp does not light up when
the seat is empty.
However, the front and side airbags for the
passenger are not activated.
Operational readiness of airbag system
As of ignition key position 1, the warning lamp
lights up briefly, thus indicating the operational
readiness of the entire airbag system and the
safety belt tensioners.

Things to remember when driving
78
Safe braking
Your BMW is equipped with ABS as standard
equipment. In situations in which it is required, it
is best to apply the brakes fully. Since the vehi-
cle maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.
Pulsation at the brake pedal combined with
sounds from the hydraulic circuits indicates to
the driver that ABS is in its active mode.
Wet roads
On wet roads or in heavy rain, briefly apply light
pressure to the brake pedal every few miles.
Watch traffic conditions to ensure that this
maneuver does not endanger other road users.
The heat that is generated by the brake applica-
tions helps to dry the brake pads and rotors.
The full braking force will then be available
when you need it.
Hills
To prevent overheating and reduced effi-
ciency of the brake system, drive long or
steep downhill grades in the gear in which the
least braking is required. Otherwise, even light
but continuous pressure on the brake can lead
to high temperatures, brake wear and possibly
even brake failure.<
The braking action of the engine can be further
intensified by downshifting, all the way down to
first gear if need be. This strategy helps you
avoid placing excessive loads on the brake sys-
tem. Downshifting in manual mode of automatic
transmission, refer to page39. When descend-
ing hills slowly, use HDC Hill Descent Control,
refer to page49.
Never drive with the clutch depressed,
with the transmission in neutral, or with
the engine switched off; otherwise, you will
have neither the braking action of the engine or
nor its power assistance to the brakes or steer-
ing.
Never allow floor mats, carpeting, or other arti-
cles to protrude into the area around the brake
or accelerator pedals and obstruct their move-
ment.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimal
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.<
Determining load limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, the vehicle
may be damaged and unstable driving con-
ditions may result.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.

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.

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

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.

2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to drawing inset.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Clean the lug bolts.
3.Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes. When you
mount wheels other than Genuine BMW
light-alloy wheels, different lug bolts may
also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the jack and remove it from beneath
the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the lug
bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. The tightening torque is
101lbft/140Nm.<
2.Stow the defective wheel in the cargo area.
3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems and valve stem
seal caps from dirt and contamina-tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to
pages51, 52.
Do not initialize the Flat Tire Monitor
when driving with a compact wheel.<
5.Replace the damaged tire with a new one as
soon as possible and have the new wheel
balanced.
Driving with compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. Do not deacti-
vate DSC; otherwise, unstable driving condi-
tions may result.<
Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. With winter tires,
these characteristics are more pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as quickly as
possible.<
Vehicle battery
Maintenance
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be happy to advise you on all questions con-
cerning the battery.
