Antilock Brake System (ABS) In the event of a fault
If the brake warning lamp
comes on red together with the
yellow indicator lamps for ABS
and DSC (refer to pages 22
and 24), ABS, CBC, DSC, DBC,
EBV and HDC have failed. You
may continue driving, but drive
defensively and with extra cau-
tion. Avoid full brake applications be-
cause the vehicle could become unsta-
ble and go out of control.
Have the system checked by the near-
est BMW center.
If all all three warning lamps come on
yellow:
ABS, CBC, DSC, DBC and HDC have
failed. The effect of the EBV Brake
Force Distribution at the rear wheels,
which achieves stable brake response,
is largely preserved. Optimum brake
force and braking stability are no longer
assured. Continue to drive; drive cau-
tiously and defensively and avoid full
brake applications.
Have the system checked by your
authorized BMW center as soon as
possible.
Following an interruption in bat-
tery power, the ABS, CBC, DSC,
DBC and HDC systems are no longer
available. After you drive for only a few
yards or meters or if you turn the steer-
ing wheel from stop to stop while the
vehicle is stationary and the engine is
running, the functions are activated
again and the three warning lamps will
go out.<

Disc brakes 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, and in op-
erating 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 be-
cause the minimal pressure which must
be exerted by the pads to clean the ro-
tors by brake applications is not
reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
For your own safety: use only
brake pads that BMW has re-
leased for your particular vehicle
model. BMW cannot evaluate non-ap-
proved brake pads to determine if they
are suited for use, and therefore cannot
ensure the operating safety of the vehi-
cle if they are installed.<
Driving notes When driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal every few
miles (kilometers). Watch 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 rotors.
Maximum braking force is obtained
while the wheels continue to rotate,
peaking when the wheels remain on the
verge of locking without actually doing
so. ABS maintains this state automati-
cally. If the ABS fails, you should revert
to the staggered braking technique
(refer to page 124).
Extended or steep mountain descents
do not necessarily have to lead to re-
duced braking efficiency. Move the se-
lector lever to the appropriate lower
range in which only minimal periodic
brake applications are required.
You can increase the engine's braking
effect by selecting progressively lower
gears, downshifting as far as 1st gear,
on steep descents. If engine braking should prove to be in-
adequate, 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), then releas-
ing the pedal, then repeating the appli-
cation. This staggered braking tech-
nique allows the brakes to cool in the
intervals between active braking
phases, preventing overheating and en-
suring that full braking capacity remains
available at all times.
Do not coast with the selector le-
ver in ÒNeutralÒ. Do not drive with
the engine shut off. The engine pro-
vides no braking effect when the trans-
mission is in ÒNeutralÒ, and there is no
power-assist for braking or steering
when the engine is not running.
Have brake inspections performed at
an authorized BMW center only. If you
do not, parts of the four-wheel drive
system could be damaged.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator and brake ped-
als and obstruct their movement.<

Brake system Winter operation Brake fluid level
The warning lamp for the brake
hydraulic system comes on, or
the CHECK BRAKE FLUID mes-
sage appears in the Check Con-
trol
*.
The brake fluid level is too low in the
reservoir (refer to page 141).
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the brake system's hydraulic
circuits.
Proceed to the nearest autho-
rized BMW center. Higher brake
application pressure may be necessary
under these conditions, and brake
pedal travel may be significantly longer.
Please remember to adapt your driving
style accordingly.<
The warning lamp also comes on when
the CHECK BRAKE LININGS message
appears in the Check Control.
Brake pads
The warning lamp for the brake
pads comes on, or the CHECK
BRAKE LININGS message ap-
pears in the Check Control
*:
The brake pads have reached their min-
imum pad thickness. Proceed to the
nearest authorized BMW center as
soon as possible to have the pads re-
placed.
For your own safety: use only
brake pads that BMW has re-
leased for your particular vehicle
model. BMW cannot evaluate non-ap-
proved brake pads to determine if they
are suited for use, and therefore cannot
ensure the operating safety of the vehi-
cle if they are installed.<
The onset of winter is often accompa-
nied by rapid changes in weather. Ad-
aptations 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. Coolant Be sure that the coolant mixture
contains the year-round ratio of 50:50
water and antifreeze/corrosion protec-
tion. This mixture provides protection
against freezing down to approx. -347
(-376). Replace the coolant every four
years. Locks BMW door lock deicer can be used to
free locks if they are frozen. This deicer
also contains lubricant.
After using the deicer, treatment with
BMW lock barrel grease is recom-
mended.

Winter operation Rubber seals and components In order to prevent the weather-strip-
ping from freezing, apply BMW rubber
treatment or silicone spray to the seals
on the doors, hood and tailgate.
A full range of car care products is
available from your BMW center.< Snow chains Mount BMW snow chains
* only on tire
size 235/65 R 17. Always mount chains
in pairs and on the rear wheels only.
Read and comply with the chain manu-
facturer's safety precautions. Do not
exceed a maximum speed of 30 mph
(50 km/h).
Starting offWhen starting in deep snow or "rock-
ing" the vehicle free, it may be advis-
able to deactivate the DSC system
briefly. Refer to page 83.
Driving on low-traction road
surfaces Use smooth, gentle pressure to control
the accelerator pedal and avoid exces-
sive engine speeds. Maintain an ade-
quate distance between yourself and
the car ahead. BrakingWinter road conditions substantially re-
duce 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. Following
that, increase pedal pressure again.
Reduce the pressure as the wheels
lock, then reapply pressure. Repeat this
braking sequence.
This type of staggered braking will re-
duce the braking distance, and the ve-
hicle still remains responsive to steer-
ing.
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 if you want to decelerate.
Doing so could cause the wheels to
lose traction and skid, thus resulting in
the loss of vehicle control.<

Winter operation Power steering Level control system

Skid control Release the accelerator pedal. Coun-
tersteer carefully and attempt to regain
control of the vehicle.Parking Place the selector lever in "Park." and
apply the parking brake when parking
on inclined surfaces. In order to prevent
the parking brake linings 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 light up
when the parking brake is ap-
plied.<
If there is a change in steering response
(difficult steering, for example) or, espe-
cially on vehicles with Servotronic
*, if
the steering "drifts" or "floats" at in-
creasing speeds:
Have your authorized BMW center in-
spect this system as soon as possible.
If the power steering fails, in-
creased effort will be required to
steer the vehicle.<
The warning lamp for the level
control system comes on, or the
message LEVEL CONTROL IN-
ACTIVE appears in the Check Control
*:
There is a malfunction in the level con-
trol system.
Stop and inspect the vehicle. If it is
riding significantly lower in the rear than
in the front, or if it is sitting at an incline
(left rear compared to right rear), con-
sult the nearest authorized BMW cen-
ter. Drive with appropriate caution in
the meantime, especially if you are driv-
ing under poor road-surface conditions.
The vehicle has reduced ground clear-
ance or driving comfort is noticeably re-
duced.
Even if the attitude of the vehicle is nor-
mal, you should consult the nearest au-
thorized BMW center if the warning
lamp indicates a system fault.

Hood To unlock Pull the lever located under the left-
hand side of the instrument panel.
Do not work on your vehicle with-
out appropriate skills. Switch off
the engine and allow it to cool down
before working in the engine compart-
ment. Always disconnect the battery be-
fore working on any electrical systems
or equipment, especially when these
are located within the engine compart-
ment. Comply with all applicable in-
structions and warnings. Failure to work
in an informed, professional manner
when servicing components and mate-
rials constitutes a safety hazard for vehi-
cle occupants and other road users. If
you are not familiar with the guidelines,
please have the operations performed
by your authorized BMW center.< 530us093
To open Pull the release handle and open the
hood. 530us094
To close Allow the hood to fall from a height of
about 12 in (30 cm) so that it audibly
engages.
To avoid injuries, be sure that the
travel path of the hood is clear
when it is closed, as with all closing
procedures.
If it is determined that the hood is not
completely closed while driving, stop
immediately and close it securely.< 530us095

Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.
To avoid the possibility of damage later
on, never use anything other than fac-
tory-approved, nitrite and amino-free
extended-duty antifreeze with corrosion
inhibitor. Your authorized BMW center
is familiar with the factory specifica-
tions.
Antifreeze and anticorrosion agents are
hazardous to health. You should always
store them in their original container
and in a location which is inaccessible
to children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethyleneÐglycol. For this rea-
son, do not spill antifreeze with corro-
sion inhibitor on hot engine parts. It
could ignite and cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor.<
Checking coolant level Correct coolant level when the engine
is cold approx. 68 7/20 6:
Unscrew the cap from the expansion
tank.
The coolant level is correct when the
end of the red float is aligned with the
upper edge of the filler opening (refer to
the arrow in the illustration), or max.
0.8 in (2 cm) higher, i. e. up to the mark
on the float (see also the schematic
diagramm next to the cap). 530us102
Adding coolant Wait until the engine cools before re-
moving the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must be lo-
cated in the blue zone. If it is not, there
is a danger of scalding.
1 Start by turning the cap counter-
clockwise. Pause to allow any accu-
mulated pressure to escape, then
open the cap.
2 If the coolant is low, slowly add
coolant until the correct level is
reached Ñ 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 re-
quired.
Replace the coolant every four years.

Changing a wheel
Safety measures in the event of a
ßat tire or wheel change:
Stop the vehicle as far as possible from
passing trafÞc. Park on a Þrm, ßat, sur-
face. Switch on the hazard ßashers.
Turn the steering wheel to the straight-
ahead position, remove the key and en-
gage the steering lock. Select ÒParkÒ po-
sition and engage the parking brake. All
passengers should be outside the vehi-
cle and well away from your immediate
working area (behind a guardrail, for in-
stance). 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 safety guidelines and
regulations. Change the wheel only on a
level, Þrm surface which is not slippery.
Avoid jacking the vehicle up on a soft or
slippery surface (snow, ice, very smooth
surfaces, etc.), since it could slide side-
ways. Position the jack on a Þrm support
surface. Do not place wooden blocks or
similar objects under the jack. If this is
done, the jack might not be able to
reach its full support capacity because
of the limited height. Do not lie under
the vehicle or start the engine when the
vehicle is supported by the jack. Failure
to comply with this creates a risk of fatal
injury.<
What you will need In order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
>Two wedges (wheel chocks)
Open the liftgate and tailgate.

5 Press the tailgate down and hold it
there. The spare wheel is now pulled
by means of the removal aid onto the
tailgate.
Hold the tailgate in the opened
position and do not allow it to re-
tract sharply upward. If you do so, there
is a risk of personal injury and vehicle
damage.< 530us158
6 Insert support rod in tailgate lock and
press down until it engages (arrow 1);
then lock hook of rod in striker
(arrow 2).
Be sure that the support rod is
locked firmly in place. If you fail to
do so, it could retract sharply upward
and cause personal injury and vehicle
damage.<
7 You can now release the locked tail-
gate and take the spare wheel down
from the tailgate. It is recommended
that you leave the tailgate locked into
place until you have completed the
wheel change and placed the wheel
with the defective tire into the re-
moval aid. 530us082

Battery Battery location The battery is located in the floor of the
vehicle below the spare wheel. Battery care The battery is maintenance-free, that is,
the original electrolyte will normally last
for the service life of the battery under
moderate climatic conditions.
For all questions that regard the
battery, please consult your BMW
center. Since the battery is mainte-
nance-free, the following is for your in-
formation only.<
Symbols You will find the following symbols on
your vehicle battery. To avoid injury,
please comply with the corresponding
precautions whenever you work with or
near the battery.
Before handling the battery,
please read the following infor-
mation:
Wear eye protection. Do not al-
low particles containing battery
acid or lead to come into con-
tact with your eyes, your skin, or your
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.
Do not allow children to have
access to batteries and battery
acid.
Never allow sparks or open
flame near the battery. Do not
smoke in the vicinity of the bat-
tery. Avoid sparks from electrical cables
or electrical equipment. Turn the key to
position 0 in the steering lock when you
are disconnecting or connecting the
battery. Never short-circuit the battery
terminals. This creates a risk of injury
from high-energy sparks.
A highly-explosive gas is
generated when the battery is
charged.
If you happen to get acid in your
eyes, rinse thoroughly for
15 minutes with clear water.
Following that, consult a physician im-
mediately. If you get acid spray on your
skin or clothing, rinse with plenty of wa-
ter. If electrolyte is accidentally swal-
lowed, consult a physician immediately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A discharged battery can freeze. Store
the battery in areas where temperature
remains above freezing.
