Parking lamps
With the switch in this position, the
front, rear and side vehicle lighting
is switched on. You can use the side
marker lamps for parking. For lighting on
one side for parking as an additional fea-
ture, refer to page 88.
Low beams
When you switch off the ignition
with the headlamps on, the head-
lamps go out, and only the parking
lamps remain on.
Pathway lighting
After parking the vehicle and switching off
the headlamps, operating the headlamp
flasher activates the low beams. You can
set the duration using the Control Center or
deactivate the function.
Control Center, for principle details, refer to
page 16:
1.Open the menu
2.Select "Vehicle settings" and press the
controller
3.Select "Lighting" and press the control-
ler 4.Select "Pathway lighting" and press the
controller
5.Turn the controller to select the corre-
sponding duration
6.Press the controller to apply the setting.
Lights on warning
If you turn the ignition key to position 0, an
acoustic signal sounds when you open the
driver's door for a few seconds to remind
you that the light has not yet been switched
off. At the same time a message appears
on the Control Display.
Daytime driving lamps*
If desired, the light switch can remain in the
low beam position:
When you switch off the ignition, the exte-
rior lighting goes out.
Always observe all applicable laws govern-
ing the use of daytime driving lamps.
You can switch on the parking lamps when
needed using the standard procedure
described under Parking lamps.
Automatic headlamp control*
When you set the switch to this
position, the system activates and
switches on and off the low beams
in response to changes in ambient light
conditions, for instance, in a tunnel, at
dawn and dusk, and in rain and snow. The
LED next to the symbol is illuminated when
the low beams are on.

The risk of hydroplaning increases as the
tread depth of the tires decreases, refer
also to Tire tread on page 173.
Water on the road
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 vehicle's engine, the electri-
cal systems and the transmission may be
damaged.<
Brakes
Your BMW is equipped with ABS as stan-
dard. The best way to achieve optimized
response from the ABS is to apply maxi-
mum pressure to the brake pedal during
emergency: panic stops. Since the vehicle
maintains steering responsiveness, you
can nevertheless avoid possible obstacles
with a minimum of steering effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Do not drive with your foot resting on
the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear and possibly
even brake failure.<
Driving in wet conditions
While driving in wet conditions and in
heavy rain, it is a good idea to apply light
pressure to 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
You can retain full and unimpaired braking
efficiency by downshifting to a gear in
which only minimal brake applications are
needed when descending long or steep
downhill stretches. You can further enhance the engine's brak-
ing effect by selecting a lower gear in the
automatic transmission's manual mode,
downshifting as far as first gear on
extremely steep stretches, refer to
pages 50 and 55. This strategy helps you
avoid placing excessive loads on the brake
system.
Never drive with the clutch pressed or
allow the vehicle to coast with the
transmission in Neutral Ð or with the engine
switched off Ð there is no engine braking
when the transmission is in Neutral, and no
power-assist for brakes and steering when
the engine is not running.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion on the brake rotors
When the vehicle is driven only occasion-
ally, 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 ten-
dency 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 pul-
sating effect that even extended applica-
tion will fail to cure.
Brake pads
The brake pad wear warning lamp
lights up and a message appears on
the Check Control. Please note any
supplementary information that appears
there.
Warning lamp for Canadian models.
The brake pads have reached their mini-
mum pad thickness. Have them replaced at
your BMW center as soon as possible.

Checking coolant level
Correct coolant level with the engine cold,
approx. +687/206:
1.Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
2.The coolant level is correct when the
coolant extends to between the MIN
and MAX marks on the filler neck, refer
to the diagram adjacent to the filler
neck
3.If the coolant is low, slowly add coolant
up to the specified level Ð do not overfill.
Brake fluid
The symbol lights up and a mes-
sage appears on the Control Dis-
play: the brake-fluid level in the
container is too low.
The brake fluid reservoir is located under
the microfilter housing trim panel on the
driver's side of the vehicle. To have brake
fluid added to the system, or to have the
source of any brake fluid loss traced and
rectified, please contact your BMW center,
which can also supply the factory-
approved Ð DOT 4 Ð brake fluids.
Brake fluid is hygroscopic: it absorbs
moisture from the atmosphere over
the course of time.
To ensure that the brake system continues
to provide safe and reliable performance,
remember to have the brake fluid changed
every 2 years at the latest, refer to page 66
and to the Service and Warranty Informa-
tion Booklet for US models or the Warranty and Service Guide Booklet for Canadian
models.
Brake fluid is toxic and also damages vehi-
cle paintwork. Always store these agents in
tightly-closed original containers kept well
away from the reach of children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. Should it come into contact with hot
engine components, the brake fluid could
ignite and cause personal injury in the form
of burns.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used brake
fluid.<
Warning lamp for Canadian models.
Brake hydraulic systems
A low brake-fluid level combined with
longer-than-usual pedal travel could be a
sign that one of the brake system's hydrau-
lic circuits has failed.
Proceed to the nearest BMW center.
Remember that pedal travel may be
increased, and there may also be a sub-
stantial increase in the amount of pedal
pressure required to brake the vehicle.
Please adapt your driving style accord-
ingly.<
