Cruise control*
The concept
You can use the cruise control feature begin-
ning at approx. 20 mph/30 km/h. The car then
stores and maintains the speed that you specify
using the lever on the steering column.
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.<

4Resuming a speed stored beforehand
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 briefly displayed in the instrument
cluster.
If the engine braking power is insufficient on a
downhill slope, the set speed may be exceeded.
On uphill gradients, it may prove impossible to
maintain the set speed if engine power output is
insufficient.
Increasing speed
Repeatedly press the lever, arrow 1, until the
desired speed is reached.
Each time the lever is pressed lightly, the speed
is increased by approx. 1 mph/1 km/h.
Accelerating using the lever
Press the lever, arrow 1, until the desired speed
is reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever, arrow 2, until the
desired speed is reached.
The functions are the same as when the set
speed is increased or the vehicle is accelerated,
except that in this case the speed decreases.
Deactivating cruise control
Tap the lever upwards or downwards, arrow3.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When you depress the clutch of a manual
transmission or shift to neutral
>When you select the automatic transmis-
sion's neutral position N
>When the vehicle travels faster or slower
than the set speed for an extended period,
e.g. when the accelerator is depressed
>When you activate DTC or deactivate DSC
>When DSC is intervening
Resuming a speed stored beforehand
Press the button, arrow4.
The last stored speed is resumed and main-
tained.
The stored speed is briefly displayed in the
instrument cluster.
The stored speed is cleared when the ignition is
switched off.

Lamps
94 until "Lighting" is selected and press the
controller.
6.Select "Daytime running lamps" and press
the controller.
The daytime running lamps are
switched on.
The setting is stored for the remote control cur-
rently in use.
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.
In tight curves at speeds up to 40 mph/70 km/h,
e.g. on mountainous roads or when turning, an
additional, corner-illuminating lamp is switched
on that lights up the inside area of the curve.
Activating Adaptive Head Light
With the ignition switched on, turn the light
switch to position 3, refer to page92.
The corner-illuminating lamp is switched on
automatically, depending on the steering wheel
angle or turn signal indicator.
To avoid blinding oncoming traffic, the Adaptive
Head Light directs light towards the front pas-
senger side when the vehicle is at a standstill.
When you are reversing, only the corner-illumi-
nating lamps are active and switched on on
both sides.
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.
High beams/roadside parking
lamps*
1High beams
2Headlamp flasher
3Roadside parking lamps

Roadside parking lamps, left or right*
There is an additional option of switching on the
lamps on the side of the car facing the road
when parked.
Switching on
After parking the vehicle, press the lever up or
down beyond the pressure point for approx.
1second, 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
Press the lever in the opposite direction to the
pressure point, arrow 3.

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 4mph or 7km/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
button again to switch between English, "E",
and German, "O".
The setting is automatically saved after approx.
10 seconds.
Glove compartment
Opening
Pull the handle.
The light in the glove compartment comes on.
To prevent injury in the event of an acci-
dent while the vehicle is being driven,
close the glove compartment immediately after
use.<
Closing
Fold cover up.
Locking
To lock the glove compartment, use the inte-
grated key of the remote control, refer to
page28.
LED hand lamp
Coupe
The LED hand lamp is stored in the glove com-
partment.
Convertible
The LED hand lamp is located in a holder inside
the glove compartment on the left side.
Insert the hand lamp into the holder with
the lens pointing toward the passenger
compartment to ensure that the lamp cannot be
switched on accidentally.<

Things to remember when driving
116 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 page83.
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 page61.
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.
Before driving into a car wash
General information on caring for your BMW
can be found on page219.

files, e. g. bit rates greater than 256 KBit/s, the
files may not play back correctly in every case.
Notes on connecting
>The USB-audio interface acts as the power
supply to the connected audio devices, pro-
vided that this is supported by the audio
device. Therefore, do not connect the USB
audio device to the power socket in the
vehicle during operation.
>Do not forcibly connect the plug to the USB
interface.
>Do not connect devices such as fans or
lamps to the USB-audio interface.
>Do not connect USB hard disks.
>Do not use the USB-audio interface to
charge external devices.

Giving and receiving assistance
232 windshield wipers may be unavailable. Power
steering assistance is not available when the
engine is not running. Thus, braking and steer-
ing 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 the selector lever position, refer to
page61.
Do not exceed a towing speed of 45 mph/
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.
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
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Do not tow the vehicle with just the rear axle
raised as this may cause the steering to turn.
Tow-starting
Avoid tow-starting the vehicle whenever possi-
ble; instead, jump-start the engine, refer to
page230. 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 the hazard warning flashers,
comply with local regulations.
2.Switch on the ignition, refer to page58.
3.Shift into 3rd gear.
4.Have the vehicle tow-started with the clutch
depressed all the way and slowly release
the clutch. After the engine starts, immedi-
ately 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.
