Ski bag
*
The ski bag allows the safe and clean
transport of up to three pairs of skis or
up to two snowboards.
The length of the ski bag and the addi-
tional space provided in the luggage
compartment make it possible to carry
skis up to 6.8 ft long (2.1 0 meters).
Because of the tapered shape of the
bag, the ski bag can only accommodate
two pairs of skis up to 6.8 ft long
(2.1 0 meters).
Loading1 Take the safety belts out of their
brackets.
2 Press button downward (arrow) and
remove the filler piece by pulling it
forward.

these load-securing devices.
>Comply with the information enclosed
with the load-securing devices.
46cde008
Always position and secure the
load correctly. If you do not, it can
endanger the passengers during
braking or evasive maneuvers.
Do not exceed the approved gross
weight and axle load (refer to page 198),
otherwise the vehicle's operating safety
is no longer assured and you are in
violation of the law.
Do not stow heavy or hard objects in
the passenger compartment without
first securing them. Otherwise they
would be thrown around during braking
and evasive maneuvers and endanger
the occupants.<

Brakes:
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 to brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This
phenomenon is referred to as aqua-
planing or hydroplaning. It is character-
ized by a partial or complete loss of
contact between the tires and the road
surface. The ultimate results are loss of
steering and braking control.
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. Otherwise, the
vehicle's engine, the electrical systems
and the transmission may be damaged.
Clothes hooks (for the hardtop):
When suspending 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.<
The catalytic converter reduces harmful
exhaust emissions.
It is designed for use with unleaded fuel
only. Even minute quantities of lead
would be enough to permanently
damage both the catalytic converter
and the system oxygen sensor.
To ensure efficient, trouble-free engine
operation and to avoid potential
damage:
>Be sure to comply with the scheduled
maintenance requirements.
>Fill the fuel tank well before it is
empty.
>Tow-start only when the engine is
cold. If you attempt to tow-start with
a warm engine, unburned residual
fuel in the catalytic converter could
ignite and cause damage. It is better
to jump-start the vehicle with outside
assistance.
>Avoid other situations in which the
fuel is not burned, or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a problem).
Never allow the engine to run with
any of the spark plug cables discon-
nected.Be sure to comply with the
preceding instructions to prevent
unburned fuel from reaching the cata-
lytic converter. If you do not, the cata-
lytic converter could respond by
overheating, leading to serious
damage.
Very high temperatures occur in any
vehicle equipped with a catalytic
converter. Heat shields are installed
adjacent to some sections of the
exhaust system. Never remove these
shields; do not apply undercoating to
their surfaces. When driving, standing
at idle, and parking the vehicle, take
extra care to avoid contact between the
exhaust system and flammable mate-
rials (grass, hay, leaves, etc.). Such
contact could lead to a fire, resulting in
serious personal injury and property
damage.<

Antilock Brake System (ABS)Antilock Brake System (ABS)/
Cornering Brake Control (CBC) CBC is an advanced engineering
design of the ABS. When braking while
cornering at high speed or braking
during high lateral acceleration, or
when braking during a lane change,
vehicle stability is improved and
steering response is enhanced.
In the event of a malfunction
The ABS warning lamp in the
instrument cluster lights up,
refer to page 22. The brake
system then reverts to conventional
operation as on vehicles without ABS.
However, have the brake system
chekked by your BMW center as soon
as possible. To prevent undetected
defects and cumulative faults from
adversely affecting the brake system,
refer any problems to your BMW center
at the earliest opportunity.
ABS warning lamp for Canadian
models.
The brake-warning lamp comes
on along with the indicator
lamps for ABS and ASC+T/DSC,
refer to page 21, then the entire
control system for ABS, CBC
and ASC+T/DSC and ADB/DBC
has failed. Continue driving
cautiously and defensively.
Avoid full brake applications. This could
cause the vehicle to lose stability and
you might no longer be able to control
it.
Have the system checked by your BMW
center as soon as possible.

Disc brakesDisc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
discs and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that must
be exerted by the pads to clean the
discs by brake applications is not
reached.
If the brake discs are corroded, they will
tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
For your own safety: use only
brake pads that BMW has
approved for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
Driving notesWhen driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brakes every few miles
or kilometers. Be aware of traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat which is generated by the brake
applications helps to dry the brake
pads and discs.
Maximum braking force is obtained
while the wheels are not locked, but
rather when they are still barely turning
immediately prior to locking. ABS main-
tains this state automatically. If the
antilock brake system ever fails, you
should revert to pumping the brakes
(refer to page 128).
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain
on the brakes and possible
impairment of the braking effect.
You can further increase the engine's
braking effect by selecting a lower gear,
downshifting as far as first gear. When
driving a vehicle with automatic trans-
mission, you can still downshift into first
gear. Refer to page 74.If engine braking should prove to be
inadequate, you should still avoid
extended, continuous braking. Instead
of maintaining low to moderate pres-
sure over an extended period of time,
you should decelerate by applying
more substantial pressure to the brake
pedal (watch for following traffic),
releasing the pedal, and then repeating
the application (staggered braking). The
cooling phases between active braking
intervals prevent the brakes from over-
heating, thus ensuring that full braking
capacity remains available at all times.
Do not coast with the clutch
depressed or with the shift lever
or selector lever in Neutral. Do not drive
with the engine shut off. The engine
provides no braking effect when the
clutch is depressed or the transmission
is in Neutral, 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 brake,
clutch or accelerator pedals, which can
obstruct pedal travel.<

Winter operationThe onset of winter is often accompa-
nied by rapid changes in weather.
Adaptations in driving style should be
accompanied by preparations on the
vehicle itself to ensure that your
progress through the winter remains
safe and trouble-free.CoolantBe sure that the coolant mixture
contains the year-round ratio of 50:50
water and extended-duty antifreeze/
corrosion protection. This mixture
provides protection against freezing
down to approx. Ð34 7 (Ð37 6).
Replace the coolant every four years.LocksBMW door lock deicer can be used to
free them if frozen. This deicer also
contains lubricant.
After using the deicer, we recommend
you treat the door lock with BMW lock
cylinder lubricant.
Rubber seals and components To prevent the weather-stripping from
freezing, apply a spray-on rubber treat-
ment or silicone spray to the door, hood
and luggage compartment lid seals.
A full range of car care products is
available from your BMW center. *
BMW snow chains can be mounted on
both summer and winter tires. Mount
them in pairs on the rear wheels only
and comply with the manufacturer's
safety precautions. Do not exceed a
maximum speed of 30 mph (50 km/h).
In this rare situation, it may be effective
to deactivate the ASC+T/DSC for a
brief period of time. Refer to page 88.
Starting offWhen starting up from a full stop in
deep snow or when "rocking" the
vehicle to free it, it may be effective to
deactivate the ASC+T/DSC system for
a brief period of time. Refer to page 88.Driving on low-traction road
surfacesUse smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. On down-
hill grades or slopes, shift down to the
next lower gear at an early point. Main-
tain an adequate distance between
yourself and the vehicle ahead.
