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 120).
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake applica-
tions 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
transmission, you can still downshift
into first gear. Refer to page 67.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 operationBrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface;
the resulting increase in braking
distance is considerable and should
always be kept in mind.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response.
If the ABS does not respond in a critical
braking situation and the wheels lock:
reduce the pressure on the brake pedal
until the wheels just start to roll again
while still maintaining enough force to
continue braking.
Then increase the pedal pressure,
reduce the pressure when the wheels
lock, reapply pressure etc.
This staggered braking procedure will
reduce stopping distances while
helping you maintain steering control.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal.Do not shift down on slick road
surfaces. Doing so could cause
the rear wheels to lose traction and
skid, that could result in the loss of
vehicle control.<
Depress the clutch during hard
braking on road surfaces that
provide only poor or uneven traction.<
Skid control Depress the clutch and let up on the
accelerator pedal, or place the selector
lever for the automatic transmission in
the "Neutral" position. Countersteer
carefully and attempt to regain control
of the vehicle.
ParkingEngage 1st or reverse gear. If your
vehicle is equipped with an automatic
transmission, place the selector lever in
Park. On vehicles with manual trans-
mission, also apply the parking brake
when parking on inclined surfaces. In
order to prevent the parking brake pads
from locking due to frost or corrosion,
dry them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic is
not endangered.
The brake lamps do not come
on when the parking brake is
applied.<

Wheel and tire combinations The right choice Use only BMW-approved tires, begin-
ning on page 127.
Due to the high speeds this vehicle can
reach, the use of specific brands,
specifications and sizes is mandatory.
Consult any BMW center for details.
Comply with local/national regulations.
The correct wheel/tire combina-
tion has an effect on the different
systems such as ABS, ATC,
ASC+T/DSC and ADB/DBC, whose
functioning would be otherwise im-
paired if the incorrect wheel/tire combi-
nations were used.
For this reason, use only tires of the
same manufacture and tread configura-
tion. In the event of a flat tire, for
example, remount the approved wheel/
tire combination as soon as possible.<
Codes on the tires and wheels The tire codes will aid you in selecting
the correct tire.
The codes on radial tires:
The speed rating indicates the approved
maximum speed for the tire.
Summer tires:
S = up to 112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 187 mph (300 km/h)
ZR = over 150 mph (240 km/h) Example:
Nominal width
in mm
Aspect ratio in X
Radial tire ID code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
225/50 R
1692W
Winter tires and all-season tires:
Q M+S = up to 100 mph (160 km/h)
T M+S = up to 118 mph (190 km/h)
H M+S = up to 130 mph (210 km/h)
Codes stamped on light-alloy wheels:
Protect tire valve from dirt by using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks. Example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop

Coolant Brake fluidAdding coolant Wait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant
temperature gauge in the instrument
cluster must be located in the blue
zone. If it is not, there is a danger of
scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open.
2 If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are
required.
Replace the coolant every four years.If the brake warning lamp comes on
and the parking brake has been
released:
Check the brake fluid level and if nec-
essary, fill it back up to the "MAX" mark.
For 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 can result in extended
pedal travel. Comply with the informa-
tion provided on page 118.
460de128
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
an authorized BMW center. Refer also
to the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models). Brake fluid is hazardous to
health and damages the vehicle's paint.
You should always store it in its original
container and in a location that is
inaccessible to children.
Do not spill the 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
environmental laws regulating
the disposal of brake fluid.<
