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 is available for activation at vehicle speeds
below 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
You can use the accelerato r or brakes to vary
this automatically cont rolled speed within a
range of between approx. 3 mph/5 km/h and
20 mph/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
over approx. 40 mph or 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.

Malfunction
The HDC display disappears during HDC
operation, or does not appear:
HDC is temporarily unav ailable due to exces-
sive brake temperature, or DSC has failed.

Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
1.Hold the car in place by depressing the
brake.
2. Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Ot herwise, the drive-off
assistant will no longer hold the car in place
after approx. 2 seconds and the car will start to
roll backwards. <
Flat Tire Monitor FTM
The concept
The system does not measure the actual
inflation pressure in the tires.
The system detects a pressure loss in a tire by
comparing the rotational speeds of the individ-
ual wheels while moving.
In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre-
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirement
The system must have be en initialized while the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured.
Each time a tire inflation pressure has been
corrected or a wheel or tire has been changed,
reinitialize the system.
System limitations
Sudden serious tire damage caused by
external influences cannot be indicated in
advance.<
A natural, steady pressure loss in all four tires is
not detected. Therefore, check the tire inflation
pressure regularly.
In the following situatio ns, the system could be
delayed or malfunction:
> System has not been initialized
> Driving on snowy or slippery road surface
> Performance-oriented style of driving: slip
in the drive wheels, hi gh lateral acceleration
> Snow chains are attached
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"
The status is displayed.
Initialization
The initialization process adopts the set infla-
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the syst em when driving with
snow chains.

Servotronic
The concept
The Servotronic varies the steering force
required to turn the wh eels relative to the
vehicle speed.
At low speeds, the steering force is strongly
assisted, i.e. less force is needed for steering.
As the vehicle speed increases, the steering
assisting power is reduced.
Malfunction
The warning lamp lights up. A mes-
sage appears on the Control Display.
Servotronic is malfunctioning or has
failed. Steering response will be different. You
can continue your journey, but moderate your
speed and exercise due caution. Have the
system checked as soon as possible.

Things to remember when driving
Vehicle equipment
In this chapter, all pr oduction, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follo w the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed an engine speed of 4,500 rpm or a
road speed of 100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full
traction potential until af ter an initial break-in
period. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clut ch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewe d in the course of the
vehicle's operating life.
Saving fuel
The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicl e serviced regularly.
Remove any unneeded cargo
Additional weight increases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove unneeded additional mirrors, the roof
rack and the rear luggage rack after use.
Mounted parts affect th e vehicle's aerodynam-
ics and increase fuel consumption.
Close the windows and glass roof
An open glass roof or window causes higher
air resistance and thus increases fuel
consumption.

Driving tipsThings to remember when driving
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to various sect ions of the exhaust sys-
tem, and never apply un dercoating to them.
When driving, standing at idle and while park-
ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could le ad to a fire, with the
risk of serious personal injuries and property
damage. Do not touch hot exhaust tail pipes.
Otherwise, there is a risk of burns. <
Mobile phones in the vehicle
It is not advisable to use wireless devices
such as mobile phones inside the vehicle
without a direct connection to an external aerial.
Otherwise, it is not poss ible to exclude the pos-
sibility of a reciprocal interference occurring
between the vehicle electronics and the wire-
less device. Otherwise, there is no assurance
that the radiation genera ted by the radio trans-
mission will be conveyed out of the passenger
compartment.<
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brak e be properly applied.<
The risk of hydropla ning increases with
declining tread depth on th e tires, refer also to
Minimum tread depth on page 251.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged. <
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise, greater
clutch wear will result. <
-For more information about the drive-off
assistant, refer to page 100.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Sinc e the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Objects in the movement range of the
pedals
Keep floor mats, carpet, and other objects
out of the movement range of the pedals;
otherwise, they may inhi bit the function of the
pedals during driving.
Do not place additional floor mats onto an
existing one or onto other objects.
Only use floor mats that have been approved for
the vehicle and can be appropriately fastened.
Make sure that the floo r mats are securely fas-
tened again after they ha ve been removed, e.g.
for cleaning. <
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pre ssure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors. Full
braking efficiency will th en be available when
you need it.

Driving tips
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least br aking is required. Even
light but consistent brak e pressure can lead to
high temperatures, brake wear and possibly
even brake failure. <
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy he lps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mo de of the automatic
transmission, refer to page 66.
Sport automatic transm ission with double
clutch: never drive with the transmission
in neutral or with the en gine switched off; other-
wise, there will be no en gine braking action and
no power assistance to the brakes and steering.
Manual transmission: never drive with the
clutch held down, with the transmission in neu-
tral or with the engine switched off; otherwise,
there will be no engine braking action and no
power assistance to the brakes and steering. <
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 le ss frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminan ts accumulate on the
brake pads. This occurs because the minimum
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.
When the vehicle is parked
Condensation forms while the automatic
climate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their
approved carrying ca pacity, never over-
load the vehicle. Overlo ading can lead to over-
heating and increases the rate at which damage
develops inside the tires. In some situations,
this can result in sudden loss of tire pressure. <
Make sure that no liquids are spilled or
leak from their containers in the trunk, as
this could result in damage to the vehicle.<
Determining loading limit
1. Locate the following statement on your
vehicle's placard:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise damage to
the vehicle may occur and unstable driving
conditions may result.<
2. Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.
4. The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
