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
factory-approved, nitrite and amino-
free extended-duty antifreeze with
corrosion inhibitor. Your BMW Sports
Activity Vehicle center is familiar with
the factory specifications.
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
reason, do not spill antifreeze with
corrosion inhibitor on hot engine parts.
It could ignite and cause serious
burns.<
Checking coolant level and
adding coolant Correct coolant level when the engine
is cold approx. +68 7(+20 6):
1. Start by turning the cap of the expan-
sion tank counterclockwise. Pause to
allow any accumulated pressure to
escape, then open
2. 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 (refer also to
the schematic diagram, next to the
cap)530us102
3. If necessary, add coolant. Slowly add
coolant until the correct level is
reached Ð do not overfill.
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<

Brake fluid
If the indicator lamp for the
brake hydraulic system appears
or if the CHECK BRAKE FLUID
warning appears in the Check
Control: the brake fluid level is
too low.
Add brake fluidThe brake fluid reservoir is located
under the microfilter housing trim panel
on the driver's side of the vehicle. For
adding brake fluid or for determining
and correcting the cause of brake fluid
loss, consult your BMW Sports Activity
Vehicle center. Your BMW Sports
Activity Vehicle center is familiar with
the specifications for factory-approved
brake fluids (DOT 4).
Brake fluid loss may result in extended
brake pedal travel. For this situation,
refer to the notes on page 135.
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 Sports Activity Vehicle 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 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 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.<

The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and oper-
ating safety Ð and as cost-effectively as
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of the vehicle. 390us008
Service Interval Display Conventional systems rely solely on
distance traveled to determine when
service is due. The BMW Maintenance
System, on the other hand, began many
years ago to take the actual conditions
under which the vehicle is driven into
consideration. After all, different drivers
can accumulate mileage in very
different ways.
From the point of view of maintenance,
62,000 miles (100,000 km) accumulated
in short-distance urban driving are not
the equivalent of the same distance
covered at moderate speeds in long-
distance highway travel.
The BMW Maintenance System
includes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the
vehicle covers every kind of operating
situation. However, even those who
drive only short distances Ð significantly
less than 6,000 miles (10,000 km) annu-
ally Ð should have the engine oil
changed at least every 2 years since oil
deteriorates over time, regardless of
use.
Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet
(Canadian models) For additional information on mainte-
nance intervals and procedures, please
refer to the Service and Warranty Infor-
mation Booklet (US models) or the
Warranty and Service Guide Booklet
(Canadian models).
As a precaution against corrosion, it is
advisable to have the body checked for
damage from rocks or gravel at the
same time, depending upon operating
conditions.
Have your BMW Sports Activity
Vehicle center do the mainte-
nance and repair.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet (US models) or the
Warranty and Service Guide Booklet
(Canadian models).
These entries will constitute your proof
that the vehicle has received regular
maintenance. They are also required for
warranty claims.<

Light-emitting diodes (LEDs) Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and
displays in your vehicle. The concept
behind their operation is related to that
employed for lasers, and they are
formally designated as Class 1 light-
emitting diodes.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours), as inflammation of the
iris could result.<
California laws require us to state the
following warning:
Engine exhaust, some of its
constituents, and certain vehicle
components contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm.<

OBD interface socket The Onboard Diagnostic (OBD) inter-
face socket is located on the left of the
driver's side at the bottom of the instru-
ment panel and under a cover. The
cover has the letters "OBD" on it.
The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system for the vehicle's
lifetime. The system monitors emission-
related components and systems for
deterioration and malfunction.530us105
An illuminated lamp informs you
of the need for service, not of
the need to stop the vehicle.
However, the systems should be
checked by your BMW Sports Activity
Vehicle center at the earliest possible
opportunity.
Under certain conditions, the indicator
will blink or flash. This indicates a rather
severe level of engine misfire. When
this occurs, you should reduce speed
and consult the nearest BMW Sports
Activity Vehicle center as soon as
possible. Severe engine misfire over
only a short period of time can seriously
damage emission control components,
especially the catalytic converter.
Service Engine Soon warning
lamp for Canadian models.
When the filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
will light up. If the filler cap is subse-
quently tightened, the indicator should
go out within a few days.<

Lamps and bulbsThe lamps and bulbs make essential
contributions to the safety of your
vehicle. For this reason, follow the
instructions below carefully when
replacing a bulb. If you are not familiar
with any of the procedures, consult
your BMW Sports Activity Vehicle
center.
Do not touch the glass portion of a
new bulb with your bare hands
since even small amounts of impurities
burn into the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW Sports Activity Vehicle
center.
Whenever working on the elec-
trical system, switch off the elec-
trical accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<

Changing a wheel Position the jack on a firm 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.

Changing a wheel Battery
The spare wheel has a size
235/65 R 17 tire. If you have
mounted tires on your vehicle with a
different size, have wheels and tires of
the same size and specification rein-
stalled as soon as possible.
When the spare wheel is mounted, the
maximum speed rating is 130 mph
(210 km/h).<
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirt in
the valve stems frequently leads to slow
leaks.
Battery posts, terminals and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
MaintenanceThe 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 Sports Activity Vehicle center.
Since the battery is maintenance-free,
the following is for your information
only.<
Do not disconnect the battery
when the engine is running. If
you do so, the ensuing voltage surge
will damage the vehicle's onboard elec-
tronics.<
Charging the battery Charge the battery in the vehicle only
when the engine is not running. Use the
connections provided in the engine
compartment (for correct connections,
refer to "Jump-starting" on page 164).
Return used batteries to a recy-
cling point or your BMW Sports
Activity Vehicle center. Maintain the
battery in an upright position for trans-
port and storage. Secure the battery
against tilting during transport.<

Do not use spray starter fluids to start
the engine.
When your battery is discharged you
can used two jumper cables to start
your vehicle with power from the
battery in a second vehicle. You can
also use the same method to help start
another vehicle. Always use jumper
cables with fully insulated handles on
the terminal clamps.
Do not touch the parts conducting
current while the engine is
running. Failure to comply with this
creates a risk of fatal injury. Carefully
observe the following instructions to
avoid personal injury and/or damage to
one or both vehicles.<
1. Be sure that the battery on the
support vehicle is also rated at
12 volts. This information is provided
on the top of the battery casing
2. Do not disconnect your battery from
your vehicle's electrical system.
Switch off all electrical accessories in
both vehicles
3. Make absolutely certain that there is
no contact between the bodywork of
the two vehicles Ð short circuit
hazard
4. Start the engine on the support
vehicle and allow it to run5. Use one jumper cable (+) to connect
the positive terminal of the battery in
the support vehicle with the auxiliary
positive terminal provided in the
engine compartment of your BMW
specifically for jump starting. The
cover on this auxiliary terminal is
identified by a "+" symbol, refer to
the illustration. To remove the cover,

jumper cable (Ð) to either the support
vehicle's negative battery terminal or
a suitable ground on its engine or
bodywork. Connect the other end to
the negative battery terminal or a
suitable ground on the vehicle being
started. There is a special nut for this
on the left side panel of your BMW.
Refer to the arrow in the illustration
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.< 530us127
7. Start the support vehicle's engine
and let it run at an increased idling
speed for a few minutes. Start the
engine on the vehicle needing the
jump-start, and allow it to run as
usual. If the first start attempt is not
successful, wait a few minutes
before another attempt in order to
allow the discharged battery to
recharge
8. Before disconnecting the jumper
cables let the engines run for a few
minutes
9. Then disconnect the jumper cables
in reverse sequence.
Depending on the cause of the fault,
have the battery recharged by your
BMW Sports Activity Vehicle center.
