Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

●

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it lights up while the vehicle is moving.
You will see how to react to this below.

Red: stop immediately

Battery charge current

●

The battery is no longer being
charged. Indicates a defective
alternator drive belt or a problem with
the alternator's charge circuit. Please
contact the nearest BMW center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

Engine oil pressure

●

Stop the vehicle immediately
and switch off engine. Check
the engine oil level and top off as
required. If the oil level is correct,
please contact the nearest BMW cen-
ter.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

To open from the inside*If the luggage compartment lid has not
been locked separately, you can open it
with this button in the footwell on the
driver's side when the vehicle is sta-
tionary.
To closeThe handle recesses in the interior trim
panel of the luggage compartment lid –
see arrows – make it easier to pull the
lid down.
To avoid injuries, be sure that the
travel path of the luggage com-
partment lid is clear when it is closed,
following the same precautions as with
all closing procedures.<
Operate the vehicle only when the
luggage compartment lid is
closed. Otherwise, exhaust fumes
could penetrate the interior of the vehi-
cle.<
Should it be absolutely necessary to
operate the vehicle with the luggage
compartment lid open:
1. Close all windows. Shut the slid-
ing/tilt sunroof
2. Greatly increase the quantity of air
coming from the air conditioning or
automatic climate control system,
see page 88 or 92.

43 Adjustments
Safe seating positionFor relaxed and fatigue-free driving you
should select a sitting position that
reflects your personal requirements. In
combination with the safety belts and
airbags, the correct seating position
plays an important role in enhancing
occupant safety in the event of an acci-
dent. To ensure that the vehicle's safety
systems provide you with optimal pro-
tection, we request that you direct your
careful attention to the following sec-
tion.
For supplementary information on
transporting children, refer to page 54.Sitting safely with airbags
Always maintain an adequate dis-
tance between yourself and the
airbags. Always hold the steering wheel
by the rim to keep any chance of injury
to hands or arms to an absolute mini-
mum should the airbag be deployed.
Never allow any objects, individuals or
animals to obstruct the areas between
passengers and airbags. Never use the
front airbag's cover as a storage tray or
support for objects of any kind. Never
allow front passengers to rest their feet
or legs on the airbag cover.<
For airbag locations and additional
information on airbags, refer to
page 52.Sitting safely with safety belts
Never allow more than one person
to wear a single safety belt. Never
allow infants or small children to ride in
a passenger's lap. Avoid twisting the
belt while routing it firmly across the
pelvis and shoulder, wear it as snugly
against your body as possible. Do not
allow the belt to rest against hard or
fragile objects. Do not route the belt
across your neck, or run it across sharp
edges. Be sure that the belt does not
become caught or jammed. Avoid
wearing bulky clothing and pull on the
lap belt periodically to retension it over
your shoulders. In the event of a frontal
impact, a loose lap belt could slide over
the hips, leading to abdominal injury. In
addition, the safety belt's restraint
effectiveness is reduced if it is worn
loosely. Expectant mothers should
always wear their safety belts, taking
care to position the lap belt against the
lower hips, where it will not exert pres-
sure against the abdominal area.<
For information on using the safety
belts, refer to page 47.
SeatsWhen adjusting your seat, always
observe the following precautions
Never try to adjust your seat while
operating the vehicle. The seat
could respond with an unexpected
movement, and the ensuing loss of
vehicle control could lead to an acci-
dent. Never ride with the backrest
reclined to an extreme angle. This is
especially important for the front pas-
senger to remember. If you do so, there
is a risk that you will slide under the
safety belt in an accident, thus reducing
the protection provided by the safety
belt.<

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.

Wheel and tire combinationsThe right choice
BMW recommends using only
wheels and tires that have been
approved by BMW for your particular
vehicle model, as otherwise body con-
tact and serious accidents can result
despite the use of the same nominal
size, e.g. due to manufacturing toler-
ances. BMW cannot evaluate all tires
and wheels on the market, and is thus
unable to guarantee that the vehicle will
continue to perform safely if unap-
proved tires and/or wheels are
mounted.<
For each tire size, BMW has assessed
the safe performance of specific tire
brands and approved them for use.
Consult any BMW center for details.
Comply with any local/national regula-
tions, for example by recording the tire
type in the vehicle documents.
The correct wheel and tire combi-
nation affects various systems
that would otherwise be impaired, for
example ABS, ASC+T/DSC and
ADB/DBC.
For this reason, use only tires of the
same manufacture and tread configura-
tion. In the event of a flat tire, for exam-
ple, remount the approved wheel and
tire combination as soon as possible.<
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel.
Winter tiresChoosing the right tireBMW recommends winter tires – M+S
tires – for operation under inclement
winter driving conditions. While all-sea-
son tires – M+S designation – provide
better winter traction than the corre-
sponding summer tires, they generally
do not achieve the performance of win-
ter tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer and
having the same tread configuration on
all four wheels.
Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by trained
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<

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.<
