HDC Hill Descent Control*
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 faster 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 decreasing speed
By accelerating or braking you can change the
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 using the cruise control
* lever on the
steering column.
1To increase speed
2To decrease speed
Activating HDC
Press the button; the indicator lamp lights up.
The indicator lamp flashes when the vehicle is
being braked automatically.
Deactivating HDC
Press the button again; the indicator lamp goes
out.
HDC is automatically deactivated in the follow-
ing situations:
>At speeds above approx. 40 mph or
60 km/h
>After switching off the ignition.
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.

2HDC display
Malfunction
The HDC display disappears during HDC oper-
ation, or does not appear:
HDC is temporarily unavailable 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.

Technology for driving comfort and safety
92 The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Depending on vehicle load,
the car may roll backwards a little during this
time span. Drive off without delay after releas-
ing the brake. Otherwise, the drive-off assistant
will no longer hold the car in place after approx.
2 seconds and the car will start to roll back-
wards.<
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor monitors tire pressures
while the car is being driven. The system
reports any significant loss of pressure in one
tire in relation to another.
If a tire loses pressure, its rolling radius
changes, and this in turn alters the speed of
rotation. This change is detected and is
reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
In the following situations, 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, high lateral acceleration
>Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Select "Settings" and press the controller.
4.Select "Vehicle / Tires" and press the con-
troller.
5.If necessary, move the highlight marker to
the uppermost field. Turn the controller
until "FTM" is selected and press the con-
troller.
6.Start the engine, but do not start driving.
7.Select "Reset" and press the controller.

device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
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 brake be properly applied.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page220.
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 with
the clutch; use the parking brake. Other-
wise greater clutch wear will result.<
For more information about the drive-off assis-
tant, refer to page91.
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. Since 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.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure 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 to ensure
that full braking efficiency will then be available
when you need it.
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 braking is required. Even
light but consistent brake 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 helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page62.
Never drive with the clutch held down,
with the transmission in idle or with the
engine switched off; otherwise, engine braking
action will not be present or there will be no
power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise pedal function could be
impaired.<
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 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.
