If you activate the system below a speed of
approx. 40 mph/70 km/h, a message will appear
stating that the system is not active until this
speed is reached.
A warning will be canceled:
>after approx. 3 seconds
>if you return to your lane
>if you brake heavily
>if you signal
System limits
The leaving lane warning cannot serve as
a substitute for your personal judgment in
determining the course of the road.
If the system issues a warning, do not move the
steering wheel with unnecessary severity, as
otherwise you could loose control of the vehi-
cle.<
The function of the system may be limited in the
following example situations:
>in heavy fog, rain or snowfall
>with worn-away, poorly visible limit lines, or
lines that run together or apart or are
unclear, e.g. in road construction areas
>when limit lines are covered by snow, ice,
dirt or a great deal of water
>in tight curves or on narrow roads
>when limit lines are not white
>when limit lines are covered by objects
>when driving up close behind a vehicle driv-
ing ahead
>with bright counter light
>when the windshield is fogged up, dirty or
covered with stickers, vignettes etc. in the
area of the inside rearview mirror

Lamps
110
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 approx. 45 mph/
70 km/h, e.g. on mountainous roads or when
negotiating curves, turning lamps are switched
on that light up the inside area of the curve.
Activating Adaptive Head Light
With the ignition switched on, turn the light
switch into position 3, refer to page108.
The turning lamps are automatically switched
on depending on the steering angle or the use
of turn signals.
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 driving in reverse, only the turning lamps
are active and illuminate the outer area of
curves.
High beams/
roadside parking lamps
1High beams
2Headlamp flasher
3Roadside parking lamps
Roadside parking lamps, left or right*
You also enjoy the option of lighting up just one
side of your vehicle when parking:
Switching on
After parking the vehicle, press the lever up or
down beyond the resistance point, arrow 3.
The roadside parking lamps drain the bat-
tery. Do not leave them switched on for
long periods of time, otherwise it may no longer
be possible to start the engine.<
Switching off
Briefly press the lever in the opposite direction
up to the resistance point, arrow3.
High-beam assistant*
The concept
This system automatically switches the high
beams on and off. A sensor on the front side of
the inside rearview mirror controls the process.
The assistant makes sure that the high beams
are switched on whenever traffic conditions
permit. This relieves you of the burden of con-
stantly switching back and forth and simulta-
neously provides you with the best possible vis-
ibility. Naturally, you can intervene at any time to
switch the high beams on and off as usual.
Activating system
1.Turn the light switch to position3, refer to
page108.
2.With the low beams switched on, briefly
press the turn signal lever in the high-beam
direction.

Things to remember when driving
136 the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, refer also to Mini-
mum tire tread on page227.
Driving through water
Do not drive through water on the road if it
is deeper than 1 ft/30 cm, and then only at
walking speed at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the
transmission may be damaged.<
Using handbrake on inclines
On inclines, do not hold the vehicle in
place for a long time by riding the clutch;
use the handbrake. Otherwise greater clutch
wear will result.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. 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.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
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 pressure on the brake pedal
can lead to high temperatures, brake wear and
possibly even brake failure.<
The braking effect of the engine can be further
increased by downshifting, if necessary all the
way down into first gear. This strategy helps
you avoid placing excessive loads on the brake
system. For information on downshifting in the
manual mode of the automatic transmission,
refer to page64.
Do not drive with the clutch depressed, in
idle or with the engine switched off, other-
wise there will be no engine braking action or
support of the braking force and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<
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 vehicle is parked
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are therefore normal.

Repeating and canceling voice
instructions
With the programmable buttons on the steering
wheel you can also make the following settings,
refer to page54:
>Repeat the voice instruction:
Press button.
>Switch voice instructions on/off:
Press button longer.
Setting volume of voice instructions
The volume can only be adjusted while a voice
instruction is being output.
1.Repeat the last voice instruction, if neces-
sary.
2.Turn the knob during the voice instruction
to select the desired volume.
This volume is independent of the volume of the
audio sources.
The setting is stored for the remote control cur-
rently in use.
Bypassing route sections
During destination guidance, you can revise the
navigation system's route recommendations to
avoid particular stretches of road. Enter the
number of miles/kilometers that you want to
travel before returning to the original route.1.Select "Navigation" and press the control-
ler.
2.Change into the third field from the top.
Turn the controller until "New route" is
selected and press the controller.
3.Turn the controller to enter the desired
number and press the controller.
The route is recalculated.
To exit from the menu without changing the
route:
Select the arrow and press the controller.
Traffic information*
In many congested areas, you can receive traf-
fic information transmitted by radio stations.
The traffic conditions are monitored by traffic
management centers and the traffic information
is periodically updated.
During destination guidance, the traffic infor-
mation relevant to your planned route is auto-
matically displayed. Whether destination guid-
ance is active or not, you can have the traffic
information displayed in the map view or in the
traffic info list.
Switching reception of traffic
information on/off
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.

Giving and receiving assistance
250 Sedan:
It is located in the toolkit in the luggage com-
partment lid, refer to page237.
Sports Wagon:
It is located in the toolkit behind the left side
panel in the cargo bay, refer to page237.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing only on roads. Avoid lateral
loading of the tow fitting, e.g. do not lift the vehi-
cle by the tow fitting. Otherwise damage to the
tow fitting and the vehicle can occur.<
Access to screw thread
Press the arrow symbol on the cover in the
bumper.

Rear
Being towed
Make sure that the ignition is switched on,
refer to page61, otherwise the low
beams, tail lamps, turn signals and windshield
wipers would not be available. Do not tow the
vehicle with the rear axle raised, as otherwise
the steering can turn to the left or right. When
the engine is stopped, there is no power assist. This then requires increased effort for braking
and steering. Active steering is deactivated and
larger steering wheel movements are
required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Manual transmission
Gearshift lever in neutral position.
Automatic and sport automatic
transmission
Before towing, manually release the
transmission lock, even if there is no mal-
function in the transmission. Otherwise there is
a risk that the transmission lock will automati-
cally be engaged during towing.<
Manually unlocking and locking transmission
lock, refer to page65.
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 vehicle by tow fitting or body
and chassis parts, otherwise damage may
result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, otherwise it
will not be possible to reliably control vehicle
response.<
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 offset
angle, please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
