Cruise control*
The concept
Cruise control is available for use at speeds of
approx. 20 mph or 30 km/h. The car then stores
and maintains the speed that you specify using
the lever on the steering column. In order to
maintain the specified speed, the system
brakes the vehicle when the engine braking
effect is insufficient on downhill gradients.
Do not use cruise control when driving at
constant speed is prevented by adverse
conditions, e.g. winding roads, dense traffic or
poor road conditions due to, e.g., snow, rain, ice
or loose surfaces. Otherwise you could lose
control of the vehicle and cause an accident as a
result.<
Manual transmission
You can shift gears while cruise control is acti-
vated. An indicator lamp notifies you that you
should shift gears when you drive for an extended period at very high or very low engine
speeds, or the system is deactivated.

Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed in the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow1, until the desired
speed is reached.
>Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.

Technology for driving comfort and safety
94 an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys-
tem, TPMS, that illuminates a low tire pressure
telltale when one or more of your tires are signif-
icantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underin-
flation has not reached the level at which the
TPMS low tire pressure telltale illuminates.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously lit. This sequence will continue
upon subsequent vehicle startups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Active steering*
The concept
Active steering varies the turning angle of the
front wheels in relation to steering wheel move-
ments. It also varies the steering force required
to turn the wheels depending on the speed at
which you are driving.
When you are driving in the low road-speed
range, e.g. in a town or when parking, the steer-ing angle increases, i.e. the steering becomes
very direct, and less effort is required to turn the
wheels. In the higher speed range, on the other
hand, the steering angle is reduced more and
more. This improves the handling capability of
your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page88.
Malfunction
The warning lamps come on. Active
steering is no longer operational. At
low speeds, greater steering wheel
movements are required, whereas at
higher speeds the vehicle reacts more sensi-
tively to steering wheel movements. The stabil-
ity-enhancing feature may also be deactivated.
Drive cautiously and think well ahead. Have the
system checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.

Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables 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.
Activating Adaptive Head Light
With the ignition switched on, turn the light
switch to the automatic headlamp control posi-
tion, refer to page97.
To avoid dazzling the drivers of oncoming vehi-
cles, Adaptive Head Light is not active when the
car is driven in reverse, and directs the light to
the front passenger's side when the vehicle is at
a standstill.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. Adaptive Head Light is
malfunctioning or has failed. Have the system
checked as soon as possible.

when parked.
Switching on
After parking the vehicle, press the lever up or
down beyond the pressure point, arrow 3.
The roadside parking lamps drain the bat-
tery. Therefore, do not leave them on for
unduly long periods of time, otherwise the bat-
tery might not have enough power to start the
engine.<
Switching off
Briefly press the lever in the opposite direction
to the pressure point, arrow 3.
Fog lamps*
The parking lamps or low beams must
be switched on for the fog lamps to
operate. The green indicator lamp in
the instrument cluster lights up whenever the
fog lamps are on.
Depending on your vehicle's equipment ver-
sion, the fog lamps are switched off when you
activate the headlamp flasher or switch on the
high beams
*.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<

Setting compass zones
Set the compass zone corresponding to your
vehicle's geographic location so that the com-pass can function correctly; refer to the world
map with compass zones below.
To set the compass zone, press the adjustment
button for approx. 3-4 seconds. The number of
the compass zone set is shown in the display.
To change the zone setting, briefly press the
adjustment button repeatedly until the display
shows the number of the compass zone corre-
sponding to your current location.
The compass is operational again after approx.
10 seconds.
Calibrating the digital compass
The digital compass must be calibrated in the
following situations:
>An incorrect compass direction is shown.
>The compass direction shown does not
change although the direction of travel
does.
>Not all compass directions are shown.
Procedure
1.Make sure that no large metal objects or
overhead power lines are in the vicinity of your vehicle and that you have enough
space to drive in a circle.
2.Set the currently valid compass zone.
3.Press the adjustment button for approx.
6-7 seconds to call up C. Then drive in at
least one full circle at a speed of no more
than 4 mph or 7 km/h.
If calibration is successful, the display
changes from C to a compass direction.
Setting right-hand/left-hand steering
Your digital compass is factory-set to right-
hand or left-hand steering, in accordance with
your vehicle.
Setting the language
You can set the language of the display:
Press the adjustment button for approx.
12-13 seconds. Briefly press the adjustment

vehicle electronics and mobile communication
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 page211.
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 page89.
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 page60.
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.

Being towed
Make sure that the ignition is switched on,
refer to page57, otherwise the low-beam
headlamps, tail lamps, turn signal indicators and
windshield wipers may be unavailable. If the
electrical system fails, do not attempt to tow-
start or tow away the car. The electric steering
wheel lock cannot be disengaged and the car is
not steerable. Jump starting, refer to page230.
Power steering assistance is not available when
the engine is not running. Thus, braking and
steering will require increased effort.<
Switch on the hazard warning flashers, depend-
ing on local regulations.
Manual transmission
Gearshift lever in idle position.
Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer to
page60.
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
In come countries, it is illegal to tow your vehicle
with a tow bar or tow rope on public highways.
Please familiarize yourself with the relevant
towing regulations for the country in which you
are driving.
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.
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.<
