Dynamic Brake Control (DBC) Disc brakesIf you step on the brake rapidly, this
system automatically produces maxi-
mum braking force boost and thus
helps to achieve the shortest possible
braking distance during "panic stops."
All of the benefits of the ABS system
are exploited under these circum-
stances.
Do not reduce the pressure on the
brake pedal for the duration of the brake
application. When the brake pedal is
released, the DBC is deactivated.
In the event of a malfunction,
the yellow brake warning lamp
comes on. Normal braking effi-
ciency and ABS are still fully
available. Have the system
checked and repaired at your
BMW center as soon as possible.
Information for your safetyNot even DBC can suspend the laws
of physics. The consequences of brake
applications with inadequate clear-
ances for safety between vehicles,
excessive speed or if aquaplaning
occurs are always the responsibility of
the driver. You should never allow the
added safety provided by DBC to mis-
lead you into taking risks of any kind.Disc 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, or in oper-
ating conditions where brake applica-
tions are less frequent, there is an in-
creased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure which
must be exerted by the pads to clean
the rotors by brake applications is not
achieved.
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.
For your own safety: use only
brake pads BMW has approved
for your specific 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.<

Disc brakes Brake systemDriving notesWhen driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brakes every few miles
or kilometers. Watch traffic conditions
to ensure that this maneuver does not
endanger other road users. The heat
which is generated by the brake appli-
cations helps to dry the brake pads and
rotors.
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 ABS
fails, you should revert to the staggered
braking technique (refer to page 91).
Long or steep mountain descents do
not necessarily lead to reduced braking
efficiency if you drive downhill with the
transmission in a gear requiring minimal
brake applications.
Braking effect on the engine can be
further increased by downshifting, into
first gear, if necessary.If engine braking should prove to be
inadequate, you should still avoid ex-
tended, continuous braking. Instead of
maintaining low to moderate pressure
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 appli-
cation (staggered braking). The cooling
phases between active braking inter-
vals prevent the brakes from overheat-
ing and retain full braking capacity.
Do not coast with the clutch de-
pressed, the gear-shift lever in
neutral, or, above all, with the engine
shutt off; otherwise, the engine will pro-
vide no braking effect if the transmis-
sion is in neutral, and there is no brak-
ing or steering power assist if the
engine is not running. Do not allow floor
mats, carpets or any other objects to
protrude into the area around the brake
pedal, the clutch or the accelerator
which could obstruct their freedom of
movement.<
Brake fluid level
The brake warning lamp comes
on with the parking brake
released:
The brake fluid level is too low in
the reservoir (refer to page 112).
If the brake fluid level is too low
and brake pedal travel has become no-
ticeably longer, there may be a defect
in one of the brake system's hydraulic
circuits.
Proceed to the nearest BMW cen-
ter. Higher brake application pres-
sure may be necessary under these con-
ditions, and brake pedal travel may be
significantly longer. Please remember to
adapt your driving style accordingly.<

Winter operationDriving on low-traction road
surfacesDo not activate the Sport Mode (refer to
page 64). Use smooth, gentle pressure
to control the accelerator pedal. Avoid
excessive engine speeds and shift to
the next higher gear at an early point.
Shift down into the next lowest gear
when approaching uphill or downhill
grades. Maintain an adequate distance
between yourself and the vehicle
ahead.BrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
The resulting increases in braking dis-
tance are considerable and should be
kept in mind at all times.
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 pressure, reduce the
pressure when the wheels lock, reapply
pressure etc.
This staggered braking procedure will
reduce braking distances while helping
you maintain steering control.
You can always then attempt to steer
around hazards after you have reduced
pressure on the brake pedal.
Do not shift down on slick road
surfaces if you want to decelerate.
Doing so could cause the wheels to
lose traction and skid, thus resulting in
the loss of vehicle control.<
Depress the clutch during hard
braking on road surfaces that pro-
vide only poor or uneven traction.<
Skid control Depress the clutch and release the
accelerator pedal. Countersteer care-
fully and attempt to regain control of the
vehicle.ParkingEngage first or reverse gear. Depending
on the steepness of the incline, you can
apply the parking brake as well. 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
engaged.<

Wheel and tire combinations The right choice Use only BMW-approved tires with
emergency driving characteristics.
Refer to page 103.
Due to the maximum speeds this vehi-
cle can reach, the use of specific brands
and sizes is mandatory. Consult any
BMW center for details. Comply with
local/national regulations.
The correct wheel/tire combinaton
affects different sytems, such as
ABS, ATC, DSC and RDW. The function
of these systems is impaired if improper
wheel/tire combinations are used.
For this reason, use only tires made by
the same manufacturer that have the
same tread configuration and possess
emergency driving characteristics. And
after a flat tire, for instance, restore the
approved wheel-tire combination as
soon as possible.<
Codes on tires and wheels The tire codes will aid you in selecting
the correct tire.
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 186 mph (300 km/h)
ZR = over 150 mph (240 km/h) For example:
Nominal width
in mm
Aspect ratio in X
Radial tire code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
245/45 R 18 96 W
Winter 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 valves from dirt by using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks.
Tires with emergency driving character-
istics also possess an additional identi-
fication mark that varies by manufac-
turer, e. g.:
Bridgestone RFT
Dunlop DSST
Goodyear EMT
Michelin ZP For example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop
center rim
Rim diameter in inches

Coolant Brake fluidAdding coolant Wait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must fall within
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 cool-
ant 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 three years.If the brake warning lamp comes on
and the parking brake has been re-
leased:
Check the brake fluid level. Fill it to the
top mark ("MAX") if necessary.
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 increase brake
pedal travel. For this type of situation,
refer to the notes on page 89.
520de093
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
a 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 toxic and eats away the
vehicle's paintwork. 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 envi-
ronmental laws regulating the dis-
posal of brake fluid.<

Battery
Battery posts, terminals, and re-
lated accessories contain lead
and lead compounds. Wash hands after
handling.<
Installation location The battery is located under the lug-
gage compartment's floor panel.Charge conditionYou can read the charge condition
of the battery with the "Magic Eye"
(hydrometer):
>Green: adequate charge
>Black: not charged adequately. The
battery must be recharged. Please
contact your BMW center for addi-
tional information
>Yellow: replace the battery.520de076
The service life specified for the
battery can be achieved only if it is
always kept adequately charged. If the
vehicle is primarily used for stop-and-
go traffic, be sure to check the charge
state often.<
MaintenanceThe battery is completely maintenance-
free. That means that the original bat-
tery acid will normally last for the ser-
vice life of the battery under moderate
climate conditions.
For all questions regarding the
battery, please consult your BMW
center. Since the battery is absolutely
maintenance-free, the following is for
your information only.<
SymbolsYou will find the following symbols on
your vehicle battery. To avoid injury,
please comply with the following pre-
cautions whenever you work with or
near the battery.
Before handling the battery,
please read the following infor-
mation.
Wear eye protection. Do not
allow particles containing bat-
tery acid or lead to come into
contact with eyes, skin, or clothing.
Battery acid is extremely corro-
sive. Wear eye protection and
protective gloves. Do not tip the
battery. Battery acid can leak from the
ventilation openings.
Be sure that children keep well
away from batteries and battery
acid.
Never allow sparks or open
flame near the battery. Do not
smoke in the vicinity of the bat-
tery. Avoid creating sparks when work-
ing around electrical cables or equip-
ment. Turn the key to position 0 in the
ignition when disconnecting or con-
necting the battery. Do not short-circuit
the battery terminals. This creates a risk
of injury from high-energy sparks.

Towing
Avoid "off-center" towing. Be sure
that the tow rope is pulled tightly
when the towing vehicle begins to
move.<
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response.<
Tow-startingFor instructions on jump starting, refer
to page 143.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
Towing a vehicle1 Put the manual-shift gear lever in
neutral
2 Towing speed:
Max. 45 mph (70 km/h)
3 Towing distance:
Max. 95 miles (150 km)
4 Leave the ignition key at position 1 to
ensure that the brake lamps, turn sig-
nals, horn and windshield wipers
remain operative, and to prevent the
steering lock detent from engaging
5 Switch on the hazard-warning system
(comply with country-specific regula-
tions).
Find some means of identifying the
vehicle in tow, e. g. place a sign or
warning triangle in the rear window.
Make sure that the ignition key re-
mains in position 1 even when the
electrical system has failed to prevent
the steering lock from engaging. The
steering and brakes are without power
assist when the engine is not running.
This means that increased effort is
required for steering and braking.<
Towing with a commercial tow
truck>Do not tow with sling-type equipment
>Use a wheel lift or flat bed equipment
>Please comply with applicable towing
laws.
Never allow passengers to ride in a
towed vehicle for any reason.
Never attach tie-down hooks, chains,
straps, or tow hooks to the tie rods, con-
trol arms, or any other part of the vehicle
suspension. If you do so, severe dam-
age will occur to these components.<520us014
