Sitting safely
The ideal sitting position can make a vital con-
tribution to relaxed driving that is as fatigue-free
as possible. The sitting position plays an impor-
tant role together with the safety belts, head
restraints and airbags in providing occupants
with maximum levels of passive safety in an
accident. Therefore, observe the following
instructions, as otherwise the protective func-
tion of the safety systems may be impaired.
For additional information on transporting chil-
dren safely, refer to page31.
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 front passenger is correctly seated
and does not place feet or legs against the
instrument panel, as otherwise leg injuries can
result if the front airbag is triggered. Never let an
occupant's head rest near or on a side airbag
because the inflating airbag could cause a seri-
ous or fatal injury.<
Even if you adhere to all the instructions, inju-
ries resulting from contact with airbags cannot
be fully excluded, 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 page31.
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 all equipped
with a safety belt.
Occupants should sit upright and be
properly restrained at all times: infants
and small children in appropriate child-restraint
systems; larger children and adults using the
safety belts.
Never allow more than one person to wear a sin-
gle safety belt. Infants and children must not
ride on a lap.
Expectant mothers should always wear their
safety belts, taking care to position the lap belt
against the lower hips, where it will not exert
pressure against the abdominal area. The
safety belt must not rest against the neck, nor
be wedged in any way or permitted to rub
against sharp edges. Avoid twisting the belt
while routing it snugly across the hips and
shoulder, as close to the body as possible, with-
out resting against hard or fragile objects. Oth-
erwise, in the event of a frontal impact, a loose
lap belt could slide over your hips, leading to
abdominal injury. Avoid wearing clothing that
prevents the belt from fitting properly and pull
the shoulder belt upward periodically to read-
just 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
page67, otherwise, the safety belt cannot exert
any restraining action.
For fastening safety belts, refer to page27.

Activating system
Press the button; the indicator lamp comes on.
The indicator lamp flashes when the brakes are
applied automatically.
Deactivating system
Press the button again; the indicator lamp 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
In vehicles with manual transmission:
Use HDC in first gear and in reverse gear, as in
the higher gears the engine's braking action
diminishes.
On vehicles with automatic transmission:
You can use HDC in every drive position.
Malfunction
If the indicator lamp in the button goes out in the
HDC mode or fails to light up when the button is
pressed:
HDC is temporarily not available, as the brake
temperature is too high.
Malfunction in vehicle stability control
systems
The warning lamp lights up yellow.
DBC Dynamic Brake Control is defec-
tive. Have the system checked as soon
as possible.
Display of the previously described
malfunction 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. Drive may
then only be carried out via the rear
axle. If the brake warning lamp lights up
yellow in the described combination,
the EBV Electronic brake-force distribution is
still available. Have the system checked as soon
as possible.
Display of the previously described
malfunction 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
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system provides an alert whenever
the inflation pressure drops significantly in rela-
tion to the pressure in another tire.

Technology for comfort, convenience and safety
50 The check of the tire inflation pressure is based
on monitoring the relative speeds of the wheels.
A flat tire is detected and reported on the basis
of a deviation in certain speed ratios.
Functional requirement
So that the Flat Tire Monitor can learn the cor-
rect inflation pressure, please perform the fol-
lowing steps:
1.Check the inflation pressures in all tires
2.Compare with the inflation pressure table
on page83 and correct if necessary
3.Initialize the system.
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires.<
In the following situations, on the other hand,
there can be delays in detecting tire pressure
losses, and even system failure:
>When driving on snow-covered or slippery
road surfaces.
>In the case of performance-oriented driving:
slip in the drive wheels, high lateral acceler-
ation.
>False alarms and undetected loss of pres-
sure may occur when you are driving with
snow chains fitted.
>When driving with a compact wheel, the Flat
Tire Monitor cannot operate.
Initializing system
Perform the initialization immediately
every time you correct the inflation pres-
sure, change a tire or change a wheel or all
wheels. This requires a trip.<1.Start the engine, but do not begin to drive.
2.Press the button until the yellow indicator
lamp in the instrument cluster lights up for a
few seconds.
3.Begin driving.
It takes a few minutes until the Flat Tire Monitor
can detect and indicate a flat tire.
Do not initialize the system when driving
with snow chains or with a compact
wheel.<
Indication of a flat tire
The warning lamp lights up yellow.
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 page99.
Brake Force Display
The Brake Force Display lights up in two
stages, depending on how heavily you brake.

Tire inflation pressure
Information for your safety
It is not merely the tire's service life, but also
driving comfort and – to a great extent – driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Checking pressure
Only check tire inflation pressure when the tires
are cold, i.e. 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 if necessary, including com-
pact wheel: at least every two weeks and before
beginning a longer trip. 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 a depressurized, i.e.
flat tire. A flat tire will seriously impair your vehi-
cle's handling and braking response. Attempts
to drive on a flat tire can lead to loss of control
over the vehicle.<
After correcting the inflation pressure(s),
always reinitialize the Flat Tire Monitor,
refer to page50.<
Inflation pressures for factory-installed
tires
The inflation pressures for your factory-
installed tires can be found on the door jamb
when you open the driver's door.
Inflation pressures for other tire sizes
The table below provides all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
For correct identification of the right tire
inflation pressure for your tires, observe
the specifications for the corresponding tire
sizes.<
Tire size
The inflation pressures apply to the tire sizes
approved and tire brands recommended by
BMW; a list of these is available from your
BMW Sports Activity Vehicle Center.

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.
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 corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle 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 pattern depth.
Tire tread
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm.
At tread depths below 0.12 in/3 mm, there is an
increased risk of high-speed hydroplaning,
even when only small amounts of water are
present on the road surface. As winter tires dis-
play a noticeable loss in their ability to cope with
cold-weather driving conditions once the tread
wears to below 0.16 in/4 mm, to ensure contin-ued 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. At a tread
depth of 0.063 in/1.6 mm these indicators, sig-
nal that the tires have reached the legally per-
missible wear limit.
Wheel/tire damage
Due to low-profile tires, please note that
wheels, tires and suspension parts are
more susceptible to road hazard and conse-
quential 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. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases reduce speed immedi-
ately. Drive carefully to the next BMW
Sports Activity Vehicle Center or tire dealer, or
have the vehicle towed to one of these locations
if necessary.
Tire damage, extending to sudden and com-
plete loss of pressure in extreme cases, can
pose a potentially lethal safety hazard for the
vehicle's occupants and other road users
alike.<

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 against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor, refer to
page49.
Do not initialize the system when driv-
ing with the 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, as otherwise unstable driving condi-
tions may result.<
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
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 consult you on all questions
concerning the battery.
Warning lamp
The warning lamp lights up. The bat-
tery is no longer being charged. The
alternator V-belt is defective or there is
a malfunction in the charge current circuit of the
alternator. Have the system checked immedi-
ately.
Do not continue driving if the V-belt is
defective. The engine could be damaged
due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.<
Charging battery
Charge the battery in the vehicle only when the
engine is not running. Use the connections pro-
vided in the engine compartment. For connec-
tions, refer to Jump starting on page104.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always secure the
battery to prevent it from tipping over during
transport.<
