xDrive
xDrive is your BMW's fo
ur-wheel-drive system.
The combined efforts of xDrive and DSC help to
further optimize traction and driving dynamics.
The xDrive four-wheel-drive system distributes
driving power variably to the front and rear axles
depending on the driving situation and road
conditions.
Hill Descent Control HDC
HDC is a downhill driving assistant that controls
your speed on steep downhill gradients and
makes it even easier to control your BMW's
handling under these conditions. The vehicle
then moves slightly fast er than double walking
speed without the driver needing to intervene.
HDC can be activated as long as you are driving
under approx. 20 mph or 35 km/h. When driving
downhill at a speed of under approx. 20 mph or
35 km/h, the vehicle's speed is automatically
reduced to slightly more than double walking
speed and maintained.
Increasing or de creasing speed
By accelerating or braking you can change this
speed within a range from approx. 3 to 15 mph,
approx. 5 to 25 km/h.
You can specify a target speed within the same
range by using the lever of the cruise control.
1 To increase speed
2 To decrease speed
Activating HDC
Press the button; the LED lights up.
When the vehicle is being braked automatically,
the LED flashes.
Deactivating HDC
Press the button again; the LED goes out.
HDC is automatically de activated at speeds
greater than approx. 35 mph/60 km/h.
Using HDC
In cars with manual transmission:
Use HDC in lower gears and in reverse gear.
With automatic transmission:
You can use HDC in any drive position.

When driving with damaged tires, the handling
characteristics ch ange, e.g. the vehicle will skid
sooner when braking, braking distances will be
longer, or self-steerin g response will change.
Adapt your driving style accordingly. Avoid
turning abruptly and driving over obstacles
such as curbs, potholes, etc.
Since the possible driving distance depends to
a considerable degree on the strain exerted on
the vehicle while driving, it can be shorter or,
with a gentle driving style, can also be longer,
depending on the speed, road condition, out-
side temperature, vehicle load, etc.
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h.
When there is a tire pressure loss, the handling
characteristics change, e.g. there will be
reduced directional stability during braking,
braking distances will be longer, and self-steer-
ing response will change. <
Vibrations or loud noises while driving can
indicate complete fa ilure of the tire.
Reduce your speed and bring the vehicle to a
stop; otherwise, tire components may become
detached, which could result in an accident. Do
not continue driving; instead, contact your
BMW center. <

Tire Pressure Monitoring Systems
Each tire should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire infl ation pressure label. If
your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, yo u 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 sys-
tem, TPMS, that illuminate s a low tire pressure
telltale when one or more of your tires are signif-
icantly underinflated. Accordingly, when the
low tire pressure telltal e illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving

General information
When the driver's door is opened with ignition
switched off, then the exterior lighting is auto-
matically switched off if the light switch is in
position 0, 2 , or 3.
Parking lamps
In switch position 1, the front, rear and side
vehicle lighting is switch ed on. You can use the
parking lamps for parking.
The parking lamps will discharge the bat-
tery. Therefore, do not leave them on for
unduly long periods of time; otherwise, the bat-
tery might not have enou gh power to start the
engine. It is preferable to switch on the left-
hand or right-hand roadside parking lamps,
refer to page 112.<
Low beams
The low beams light up wh en the light switch is
in position 2 and the ignition is on.
Automatic headlamp control
When the switch is in position 3, the low beams
are switched on and off automatically depend-
ing on ambient lighting conditions, e.g. in a tun-
nel, in twilight, or if there is precipitation. The
Adaptive Light Control is active. The LED next
to the symbol is illu minated when the low
beams are on. You can also activate the daytime
running lights, refer to page 111. In the situa-
tions described above, the lamps then automat-
ically switch from daytime running lights to low
beams.
The headlamps may also come on when the
sun is sitting low on a blue sky.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps. <
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the system
cannot detect fog or ha zy weather. To avoid
safety risks, you should always switch on the
low-beam headlamps ma nually under these
conditions. <

Adaptive Light Control
The concept
Adaptive Light Control is a variable headlamp
control system that en ables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
I n t i g h t c u r v e s a t s p e e d s u p t o 4 0 m p h / 7 0 k m / h ,
e.g. on mountainous roads or when turning, an
additional, corner-illumina ting lamp is switched
on that lights up the inside area of the curve.
Activating Adaptive Light Control
With the ignition switched on, turn the light
switch to position 3, refer to page 110.
The corner-illuminating lamp is switched on
automatically, depending on the steering wheel
angle or turn signal indicator.
Standstill function: to avoid blinding oncoming
traffic, the Adaptive Light Control directs light
toward the front passenge r side when the vehi-
cle is at a standstill.
When you are reversing, only the corner-illumi-
nating lamps are switched on and active on
both sides.
Malfunction
The warning lamp lights up. A mes-
sage appears on the Control Display.
The Adaptive Light Control is mal-
functioning or failed. Ha ve the system checked
as soon as possible.

High-beam Assistant
The concept
This system automatica
lly switches the high
beams on and off. The procedure is controlled
by a sensor on the front of the interior rearview
mirror. The assistant ensures that the high
beams are switched on whenever the traffic sit-
uation allows. It handle s this task for you and
gives you the benefit of the best possible view.
You can intervene at any time and switch the
high beams on and off as usual.
Activating the system
1. Turn the light switch to position 3, refer to
page 110.
2. With the low beams switched on, briefly
push the turn signal/high beam lever in the
direction of the high beam.
The indicator lamp in the instrument
cluster lights up when the high beams
are activated. The system automati-
cally switches from hi gh beams to low beams
and vice versa in response to oncoming traffic,
traffic ahead of you, and adequate ambient
lighting, e.g. on city streets.
Switching the high beams on and off
manually
Whenever you wish, or when the situation
requires, you can intervene:
> If the High-beam Assistant switches on the
high beams, but you would like to drive with
the low beams, simply switch off the high
beams using the turn signal/high beam
lever. This deacti vates the High-beam
Assistant.
To reactivate the syst em, briefly push the
turn signal/high beam lever toward the high
beams again. >
If the High-beam Assistant switches on the
low beams, but you would like to drive with
the high beams, switch on the high beams
as usual. This deacti vates the system and
the high beams need to be switched off
manually, if necessary.
To reactivate the system, briefly push the
turn signal/high beam lever toward the high
beams again.
> Use the headlamp flasher as usual with the
low beams switched on.
System limitations
The High-beam Assistant cannot serve
as a substitute for the driver's personal
judgment of when to use the high beams.
Therefore, manually switch off the high beams
in situations where this is required to avoid a
safety risk.<
The system is not fully fu nctional in situations
such as the following, and driver intervention
may be necessary:
> In very unfavorable weather conditions,
such as fog or heavy precipitation
> In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings
> In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on highways
> In poorly lit towns and cities and in the pres-
ence of highly reflective signs
> At low speeds
> When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov-
ered with stickers, etc.
> If the sensor is dirty. Clean the sensor on
the front of the interior rearview mirror using
a cloth moistened with a small amount of
glass cleaner.
