Self-leveling suspension
*
2-axle self-leveling suspension
*
The warning lamp for the self-
leveling suspension comes on,
or the message "SELFLEVEL
SUSP.INACT" appears in the Check
Control: there is a malfunction in the
self-leveling suspension.
Stop and inspect the vehicle. If the rear
of the vehicle is visibly lower than the
front, possibly accompanied by a tilt
noticeable when you compare the left
rear with the right rear, please respond
by immediately proceeding to the near-
est BMW Sports Activity Vehicle center.
Drive with appropriate caution in the
meantime. The vehicle has reduced
ground clearance and driving comfort
may be noticeably reduced.
Even when the position of the vehicle is
normal, have the system checked as
soon as possible when a malfunction is
indicated.
The concept Your vehicle is equipped with 2-axle
self-leveling suspension acting on both
the front and rear suspension. This sys-
tem combines automatic self-leveling,
which compensates for variations in
front-to-rear load-distribution patterns,
with a selection feature allowing drivers
to choose from among several ride-
height options.
You may choose from among the fol-
lowing ride heights:
>Normal
The standard setting is intended for
most operating conditions, including
trailer towing
>Off-Road
Increased level for more ground
clearance
>Access
Lowers vehicle for more convenient
cargo handling or easier passenger
entries and exits.
Changes in ride height are initiated
either manually, using the control but-
ton, refer to page 98, or automatically in
response to specific speeds. When the
ride height is selected manually, the
driver has the additional option of revis-
ing the ride-height selection by entering a new command during the adjustment
process.
When the vehicle is stationary, the sys-
tem executes ride-height changes in
both directions – up and down – when-
ever the doors are closed. The liftgate/
tailgate may be open. The system
raises the vehicle only when the engine
is running.
The system's automatic self-leveling
feature automatically compensates for
variations in the vehicle's load.
Frequent changes in ride height
initiated at short intervals can
overheat the compressor, causing the
system to briefly suspend active opera-
tion.<

100n
Flat Tire MonitorThe concept The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires
as you drive. The system provides an
alert whenever the inflation pressure
drops significantly in relation to the
pressure another tire.
The check of the tire inflation pressure
is based on monitoring the relative
speeds of the wheels. A flat is detected
and reported on the basis of a deviation
in certain speed ratios.Functional requirementTo ensure reliable operation, the sys-
tem should have been initialized with
the correct tire inflation pressure.
System limits
The Flat Tire Monitor cannot indi-
cate sudden severe tire damage
caused by outside factors and does not
detect a natural, even pressure drop in
all four tires.<
In the following situations, the system
could be delayed or malfunction:
>When driving on snow-covered or
slippery road surfaces
>In the case of performance-oriented
driving: slip on the drive wheels, high
lateral acceleration
>False alarms and undetected loss of
pressure may occur when you are
driving with snow chains fitted.
Initializing system
Perform the initialization immedi-
ately every time you correct the
inflation pressure, change a tire or
change a wheel or all wheels. A drive
is required for this purpose.<
1. Start the engine, but do not drive off
2. Press the button until the yellow indi-
cator lamp in the instrument cluster
lights up for a few seconds
3. Drive off.
It takes a few minutes of driving until
the Flat Tire Monitor can detect and
indicated a flat tire.
When driving with snow chains,
do not initialize the system.<

Driving your X5 On bad roads When you are driving on bad roads,
there are a few points which you should
strictly observe — for your own safety,
for that of your passengers, and for the
safety of the vehicle:
Driving on unpaved terrain can
cause damage to the vehicle.<
>Always adapt the driving speed to the
road conditions. The rougher or
steeper the road surface is, the lower
the speed should be
>You can operate your vehicle on
uphill and downhill gradients with a
maximum slope of 50 %. If you want
to drive on uphill or downhill gradi-
ents of this kind, make sure before-
hand that the engine oil and coolant
levels are near the max mark. Refer
to pages 148 and 150.
Use the HDC Hill Descent Control on
steep downhill gradients, refer to
page 96.
It is possible to start off on gradients
of up to 32 %.
The permitted side tilt is also 50 %
>While driving, watch carefully for
obstacles such as rocks or holes. Try
to avoid these obstacles whenever
possible
>Please note that, for example on
crests and bumpy roads, the body
can make ground contact.
The ground clearance of the vehicle
is:
– 8 in/200 mm with up to four persons
– 7 in/180 mm fully loaded, without
self-leveling suspension
>Only drive through water up to a
maximum depth of 20 in/50 cm and
only at walking speed, making sure
not to stop in the process.
After leaving the water, press on the
footbrake gently several times while
driving at a low speed. The brake
applications will help to dry the
brakes, thus preventing a reduction in
braking performance caused by the
moisture.
Back onto paved road In recommending that you observe the
following points after driving on adverse
road surfaces, it is not as a beauty
treatment for your BMW. Instead, it is
intended for the maintenance of driving
safety:
>Clean the largest accumulations of
dirt from the body and check the
underbody for damage
>Clean mud, snow, ice etc. from the
wheels and tires and check the
wheels for damage
>Check to determine whether rocks,
gravel or accumulations of dirt on the
brake rotors and calipers could influ-
ence braking performance. Remove
all such foreign objects
>In order to clean the brake rotors,
apply the footbrake gently several
times while driving at a low speed.
Be sure that following traffic is not
endangered by this
>For cleaning the handbrake, apply
the lever slightly at approx. 25 mph/
40 km/h and continue to drive for
approx. 200 yards/200 meters, pro-
vided that traffic conditions allow you
to do so.

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.<
