Washer fluid Engine oilWindshield and headlamp washer
system Approximate capacity is 8.2 quarts/
7.8 liters.
Fill with water and — if required — with
the addition of a washer antifreeze,
according to manufacturer's recom-
mendations.
We recommend that you mix the
washer fluid before adding it to
the reservoir.<
Antifreeze agent for the washer
systems is inflammable. For this
reason, keep it away from sources of
flame and store it only in its original
containers. Store it so that it is inacces-
sible to children. Comply with the
instructions on the containers.< 530de298
Checking oil level 1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating tempera-
ture
3. After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean
lint-free cloth, paper towel, or similar
material
4. Push the dipstick carefully all the way
into the guide tube and pull it out
again
5. The oil level should be in between
the two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions. 530us100
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts/1 liter. Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.
X5 4.8is:
With a very sporty driving style, the
engine oil level should be at the upper
mark on the dipstick.530us205

Coolant
Do not add coolant to the cooling
system when the engine is hot.
Escaping coolant can cause burns.<
Coolant consists of water and coolant
additive. Not all commercially available
additives are suitable for your BMW.
Ask your BMW Sport Activity Vehicle
center for suitable additives.
Only use suitable additives, as
otherwise engine damage may
result. The additives present a health
hazard.<
Always observe all applicable
environmental rules and regula-
tions when disposing of used coolant
additives.<
Checking coolant level 1. The engine must be at ambient tem-
perature
2. Start by turning the cap of the expan-
sion tank counter-clockwise. Pause
to allow any accumulated pressure to
escape, then open
3. 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 cap530us102
4. If the coolant is low, slowly add cool-
ant up to the specified level – do not
overfill
5. Twist closed the cap and tighten
firmly
6. Have the reason for the coolant loss
eliminated as soon as possible.

Brake fluidBrake fluid level
If the warning lamp lights up
or the message "CHECK
BRAKE FLUID" appears in the
Check Control: stop immedi-
ately. The brake fluid in the res-
ervoir has fallen to below the
minimum level.
Add brake fluid The 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
DOT 4 brake fluids.
Brake fluid loss may result in extended
brake pedal travel. For this situation,
refer to the notes on page 139.
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 for US models or
the Warranty and Service Guide Book-
let for Canadian models.
Brake fluid is toxic and also damages
vehicle paintwork. Always store these
agents in tightly-closed original con-
tainers kept well away from the reach of
children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Always observe all applicable
environmental rules and regula-
tions when disposing of used brake
fluid.<

The BMW Maintenance System is
designed in such a way that it reliably
ensures the road safety and operating
reliability of the vehicle, keeping the
cost for you as low as possible.
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.
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 390us008
can accumulate mileage in very differ-
ent 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, significantly
less than 6,000 miles/10,000 km annu-
ally, should have the engine oil changed
at least every 2 years since oil deterio-
rates over time, regardless of use. Service and Warranty Information
Booklet for US models/Warranty
and Service Guide Booklet for
Canadian models For additional information on mainte-
nance intervals and procedures, please
refer to the Service and Warranty Infor-
mation Booklet for US models or the
Warranty and Service Guide Booklet for
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 for US models or
the Warranty and Service Guide Book-
let for Canadian models.
These entries will constitute your proof
that the vehicle has received regular
maintenance. They are also required for
warranty claims.<

An illuminated indicator lamp
informs you of the need for ser-
vice, not of the need to stop the
vehicle. However, the systems should
be checked by your BMW Sports Activ-
ity Vehicle center at the earliest possi-
ble opportunity.
Display of the previously
described malfunction on Cana-
dian models.
Under certain conditions, the indicator
lamp 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.
When the filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
lamp will light up. If the filler cap is sub-
sequently tightened, the indicator lamp
should go out within a few days.<

Lamps and bulbs The lamps and bulbs make essential
contributions to the safety of your vehi-
cle. For this reason, follow the instruc-
tions below carefully when replacing a
bulb. If you are not familiar with any of
the procedures, consult your BMW
Sports Activity Vehicle center.
Never touch the glass on new
bulbs with your bare fingers, as
even minute amounts of contamination
will burn into the bulb's surface and
reduce its service life. 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 cen-
ter.
To prevent short circuits, before
working on any electrical system,
equipment or accessory you should
always switch it off and disconnect the
cable from the battery's negative termi-
nal before starting.
To avoid possible injury or equipment
damage when changing bulbs, observe
any instructions provided by the bulb
manufacturer.<

Changing a wheel Battery 10. Screw in the remaining lug bolts.
Tighten all the bolts securely in a
diagonal pattern
11. Lower the jack and remove it from
beneath the vehicle
12. Tighten the lug bolts in a diagonal
pattern
13. Check and correct the tire inflation
pressure at the earliest opportunity.
After mounting the spare wheel or
correcting the inflation pressure,
reinitialize the Flat Tire Monitor,
refer to page 100.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirt in
the valve stems frequently leads to slow
leaks.
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure safety, always have the lug
bolts checked with a calibrated torque
wrench as soon as possible to ensure
that they are tightened to the speci-
fied torque. The tightening torque is
101 lb-ft/140 Nm.<
Store the wheel and the tools in the
order opposite that for removal.
Before removing the support rod,
be sure that the tailgate is held
down firmly. If you fail to do so, it could
retract sharply upward and cause per-
sonal injury and vehicle damage.
After you remove the rod, close the tail-
gate carefully. Continue to hold it firmly
until it is completely closed.<
If light-alloy wheels other than Genuine
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
Driving with spare wheel
Do not exceed a speed of
130 mph/210 km/h, as otherwise
accidents may occur due to tire dam-
age.<
With certain wheel-and-tire com-
binations the size of the spare
wheel differs from that of the other
wheels. However, to restore the original
state, the normal wheel should be
remounted as soon as possible.<
Battery posts, terminals and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
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. Your
BMW Sport Activity Vehicle center will
be glad to advise in all matters con-
cerning the battery.Charging battery Only charge the battery in the vehicle
via the terminals in the engine compart-
ment with the engine off. For correct
connections, refer to Jump-starting on
page 171. Disposal
Following replacement, have old
batteries disposed of by your
BMW Sports Activity Vehicle center or
hand them in to a recycling center.
Maintain the battery in an upright posi-
tion for transport and storage. Always
restrain the battery to prevent it from
tipping over during transport.<

Jump-starting When your battery is discharged you
can used two jumper cables to start
your vehicle with power from the bat-
tery in a second vehicle. You can also
use the same method to help start
another vehicle. Use only jumper cables
with fully-insulated clamp handles.
To avoid the risk of potentially
fatal injury, always avoid all con-
tact with electrical components while
the engine is running. Carefully observe
the following instructions to avoid per-
sonal injury and/or damage to one or
both vehicles.<
Preparing1. Check whether the battery of the
other vehicle has a voltage of
12 Volts and approximately the same
capacitance in Ah. This information
can be found on the battery
2. Switch off the engine of the support
vehicle
3. Switch off any electrical systems and
components in both vehicles.
Ensure that no contact exists
between the bodywork on the two
vehicles, otherwise there is a danger of
short circuits. To avoid personal injury from
sparks, always observe this
sequence when connecting jumper
cables.<
On your BMW the so-called jump-start
connection point in the engine com-
partment acts as the battery positive
terminal, also refer to the engine com-
partment overview on page 147. The
cover cap is marked with +.
1. Fold up the cap of the BMW auxiliary
terminal for jump-starting, refer to
arrow
2. Connect one terminal clamp of the
positive/+ jumper cable to the posi-
tive terminal of the battery or an aux-
iliary terminal for jump-starting of the
vehicle providing starting assistance
3. Connect the second terminal clamp
of the positive/+ jumper cable to the
positive terminal of the battery or to
an auxiliary terminal for jump-starting
of the vehicle to be started530de325
