Driving notes
Brakes: do not drive with your foot
resting on the brake pedal. Even
light but consistent pressure on the
brake pedal can lead to high tempera-
tures, accelerated brake wear and pos-
sibly even brake failure.
Hydroplaning: when driving on wet or
slushy roads, reduce your speed. If you
do not, a wedge of water may form
between tires and road surface. This
phenomenon can lead to partial or
complete loss of contact between the
tires and road surface, as well as loss of
vehicle control and braking ability.
Driving through water: do not drive
through water on the road if it is deeper
than 1 ft/30 cm, and then only at walk-
ing speed. Otherwise, the vehicle's
engine, the electrical systems and the
transmission may be damaged.
Rear parcel tray: never use it to store
heavy or hard objects, as otherwise
occupants could be injured during
braking maneuvers.
Clothes hooks: when hanging clothing
from the hooks, be sure that they will
not obstruct the driver's vision. Do not
hang heavy objects on the hooks. If you
do so, they could cause personal injury
during braking or evasive maneuvers.<
Antilock Brake System (ABS)The conceptABS keeps the wheels from locking
during braking, thereby enhancing
active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply maxi-
mum pedal pressure – panic stop.
Since the vehicle maintains steering
responsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.Dynamic Brake Control (DBC)DBC is included in the DSC, refer to
page 79.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest-possible braking
distances during "panic stops." This
system exploits all the benefits of ABS.Do not reduce the pressure exerted
against the brake pedal until the brak-
ing maneuver has been completed.
DBC is deactivated when you release
the brake pedal.
Cornering Brake Control (CBC)CBC is an advanced engineering devel-
opment of ABS. When braking during
cornering with high lateral accelera-
tion, or when braking during a lane
change, vehicle stability is improved
and the steering response is enhanced.

Brake systemBrake fluid levelIf the brake fluid level is too low and
brake pedal travel has become longer,
there may be a defect in one of the
brake system's hydraulic circuits.
Proceed to the nearest BMW cen-
ter. It may be necessary to apply
higher levels of pressure to the pedal
when stopping and braking distances
may also be longer. Please remember
to adapt your driving style accord-
ingly. with the vehicle parked or in storage,
and operating conditions in which brak-
ing is restricted to gentle, low-pressure
applications will all increase the ten-
dency for corrosion to form on the
rotors; this is often accompanied by a
simultaneous accumulation of contami-
nation on the brake pads. The pads
must exert a certain minimal level of
pressure against the rotors for the disc
brakes' inherent self-cleaning effect to
remain effective; the pressure available
under the above conditions may not
provide adequate cleansing.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
When driving in heavy rain and on wet
roads 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
pose a hazard to you or to other road
users. The heat generated in this pro-
cess helps dry the pads and rotors to
ensure that your brake system will
respond with undiminished efficiency
when you need it.
When descending steep hills and
extended grades, downshift to a gear
that will allow you to continue safely
with only a minimal amount of braking.
By minimizing the loads placed on the
brake system, this strategy helps
ensure that optimal brake system
response will remain available at all
times. Use care to avoid exceeding the
approved engine-speed range, refer to
page 70.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in Neutral. Do not
coast with the engine shut off. The
engine provides no braking effect when
the clutch is depressed and there is no
power-assist for braking or steering
when the engine is not running.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment. For your own safety: use only
brake pads that BMW has
released for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suitable for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<

Brake fluidIndicator lamp
The brake warning lamp comes
on when the parking brake is
not engaged: the brake fluid
level is too low, refer to page 18.
Parking brake warning lamp for
Canadian models.
Adding brake fluidFor adding brake fluid or for determin-
ing and correcting the cause of brake
fluid loss, consult your BMW center.
Your BMW center is familiar with the
specifications for factory-approved
brake fluids – DOT 4.
Brake fluid loss may result in extended
brake pedal travel. Refer to the informa-
tion on page 110.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the brake system's
safety and reliability, have the brake
fluid changed every two years by a
BMW center. Refer to the Service and
Warranty Information Booklet for US
models or the Warranty and Service
Guide Booklet for Canadian models.
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion which is out of reach of children.
Do not spill the brake fluid and do not
fill the brake fluid reservoir beyond the
MAX mark. The brake fluid could ignite
upon contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of brake fluid.<

Changing a wheel
Safety precautions in the event of
a flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat sur-
face. Switch on the hazard warning
flashers. Turn the steering wheel to the
straight-ahead position and engage the
steering lock. Shift into 1st or Reverse,
or if you have an automatic transmis-
sion, position the selector lever in Park,
and engage the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area, behind a guardrail,
for example.
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all local safety guidelines and reg-
ulations.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle on a soft or slippery
support surface – snow, ice, loose
gravel, etc. – as either the vehicle or the
jack could slip sideways.
Position the jack on a firm support sur-
face.
Do not place wooden blocks or similar
objects under the jack. They could pre-
vent the jack from extending to its full
height and reduce its support capacity.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack. There is otherwise a risk of
fatal injury.<

Run Flat tires*Run Flat tires are labeled on the side-
wall with a circular symbol containing
the letters RSC. Run Flat tires consist of
self-supporting tires and special rims.
The tire reinforcement ensures that the
tire retains some residual safety in the
event of pressure drop and driving
remains possible to a restricted degree.
The vehicle is equipped with the Flat
Tire Monitor or Tire Pressure Monitor
(TPM), which indicate a flat tire.
Because the sides of Run Flat
tires are reinforced, a drop in infla-
tion pressure usually cannot be
detected from the outside.<
Flat tireIf there is a tire failure, the red warning
lamp symbol lights up. This visual alert
is accompanied by an acoustic warning
signal.
Additional information on the Tire Pres-
sure Monitor or Flat Tire Monitor is
found beginning on page 81.
Reduce vehicle speed carefully to
under 50 mph / 80 km/h, avoiding hard
brake applications and steering maneu-
vers.
If it can not be determined immediately
from the outside which wheel is defec-
tive, check the tire inflation pressure at
all four wheels.
Have Run Flat tires replaced by
your BMW center. In the interest
of safety, Run Flat tires should not be
repaired. Your BMW center has the
information needed for working with
Run Flat tires and is equipped with the
necessary special tools.<
If appropriate, please consult your
BMW center to reequip your vehi-
cle from summer to winter tires – or vice
versa.<
Driving with a damaged tireRun Flat tires allow you to continue
driving to a restricted degree at a maxi-
mum speed of 50 mph / 80 km/h
depending on the cargo load and the
extent of tire damage. You can deter-
mine the distance you may continue
driving on the basis of the following val-
ues:
>Tire inflation pressure of 0 psi/
0 kilopascal (kPa):
approx. 100 miles/150 km
>Tire inflation pressure of approx.
7-15 psi/50-100 kPa:
approx. 300 miles/500 km
>Tire inflation pressure greater than
15 psi/100 kPa:
approx. 600 miles/1,000 km.
Drive cautiously. Do not exceed a
speed of 50 mph / 80 km/h. Be
aware that vehicle handling will be
altered when there is a loss in inflation
pressure. Anticipate, e.g., reduced
tracking during braking, longer braking
distances and changed steering char-
acteristics.<
