84
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 deactivated 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.

1Display for target speed
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.
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. Otherwise, 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 Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. 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:

Things to remember when driving
120 The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page209.
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 assis-
tant, refer to page84.
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 page58.
Never drive with the clutch held down,
with the transmission in neutral 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.
When the vehicle is parked
Condensation forms while the automatic cli-
mate 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 capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage

Using a tow fitting
The screw-in tow fitting must always be carried
in the car. It can be screwed in at the front or
rear of the BMW.
Coupe: it is stored in the onboard vehicle tool kit
underneath the cover on the right-hand side of
the cargo area, refer to page223.
Convertible: it is stored in the onboard vehicle
tool kit underneath the cargo area floor, refer to
page223.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing on paved roads only. Avoid
lateral loading of the tow fitting, e.g. do not lift
the vehicle by the tow fitting. Otherwise, the
tow fitting and the vehicle could be damaged.<
Access to screw thread
Release the cover panel in the bumper:
Press on the upper part of the cover panel.

Being towed
Make sure that the ignition is switched on,
refer to page55; otherwise, the low-beam headlamps, tail lamps, turn signal indicators and
windshield wipers may be unavailable.
Power steering assistance is not available when
the engine is not running. Thus, braking and
steering will require increased effort. Active
steering is not active and it will be necessary to
turn the steering wheel further.<
Manual transmission
Gearshift lever in neutral position.
Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer to
page58.
Do not exceed a towing speed of 45 mph
or 70 km/h and a towing distance of
90 miles/150 km; otherwise, the automatic
transmission may be damaged.<
Towing methods
Do not lift the vehicle by a tow fitting or
body and chassis parts; otherwise, dam-
age may result.<
With a tow bar
The towing vehicle must not be lighter
than the towed vehicle; otherwise, it may
be impossible to maintain control.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.
Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
With a tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.

Giving and receiving assistance
234 To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Attach the tow rope to the tow fittings only, as
attaching it to other parts of the vehicle could
result in damage.<
With a tow truck: vehicle without xDrive
Manual and automatic transmission:
Have the BMW transported with a tow truck
with a so-called lift bar, or on a flatbed.
Do not tow the vehicle with just the rear axle
raised as this may cause the steering to turn.
With a tow truck: vehicle with xDrive
Do not tow a BMW with xDrive with just
the front or rear axle raised; otherwise, the
wheels could lock up and the transfer case
could be damaged.<
Have the BMW transported on a flatbed surface
only.
Tow-starting
Avoid tow-starting the vehicle whenever possi-
ble; instead, jump-start the engine, refer to
page231. Vehicles with a catalytic converter
should only be tow-started when the engine is cold, vehicles with an automatic transmission
cannot be tow-started at all.
1.Switch on hazard warning flashers, comply
with local regulations.
2.Switch on the ignition, refer to page55.
3.Shift into 3rd gear.
4.Have the vehicle tow-started with the clutch
depressed and slowly release the clutch.
After the engine starts, immediately
depress the clutch completely again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
With xDrive: do not activate Hill Descent
Control HDC when the vehicle is being
tow-started, page83.<
