Technology that monitors itself
The indicator and warning lamps identified
by the
+ symbol are subjected to an oper-
ation check each time you switch on the
engine. They each light up once for differ-
ent periods of time.
When a malfunction occurs in a monitored
system, the corresponding lamp will either
fail to go out when the engine is started, or
it will come on again during normal driving.

All vehicle systems are ready for operation.
3 Engine start
Engine
Do not allow the engine to warm up while
idling. Drive off immediately at moderate
engine speed.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at startup are normal and should decrease as the engine warms up. If engine
speed does not decrease, service is
required.
To prevent the battery from discharging,
always switch off electrical devices which
are not in use and the ignition when the
vehicle is not being driven.
Do not run the engine in closed
rooms, as otherwise inhaling toxic
exhaust gases can cause unconsciousness
and death. The exhaust gases contain car-
bon monoxide, an odorless and colorless,
but highly toxic gas. Do not leave the vehi-
cle unattended with the engine running,
since an unattended vehicle with a running
engine represents a safety hazard.
When driving, standing at idle and while
parking take care to avoid possible contact
between a hot exhaust system and any
highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead
to a fire, resulting in serious personal injury
and property damage.<
Indicator lamps
If the Service Engine Soon indicator
lamp comes on either continuously
or intermittently, this indicates a
fault in the emissions-related electronic
systems. Although the vehicle remains
operational, you should have the systems
checked by your BMW Sports Activity
Vehicle Center at the earliest possible
opportunity.
The illuminated indicator informs you of the
need for service, not that you need to stop
the vehicle. However, the systems should
be checked by your BMW Sports Activity
Vehicle Center at the next opportunity.
If the indicator blinks or flashes, this indi-
cates a high level of engine misfire. Reduce
speed and contact the nearest BMW
Sports Activity Vehicle Center immediately.
Severe engine misfiring over even a short
period of time can seriously damage emis-

Do not actuate the starter for too
short a time. Do not turn it for more
than approx. 20 seconds. Release the igni-
tion key immediately as soon as the engine
starts.<
If the engine fails to start on the first
attempt, for instance, if it is very hot or cold:
>Press the accelerator pedal halfway
down while engaging the starter.
During a cold start at very low tempera-
tures, as of approx. +57/Ð156, at high
altitudes over 3,300 ft/1,000 m:
>For the first attempt, run the start for
longer, approx. 10 seconds
>Press the accelerator pedal halfway
down while engaging the starter.
Avoid frequent starting is quick suc-
cession or repeated start attempts in
which the engine does not start. Otherwise,
the fuel is not burned or inadequately
burned and there is a danger of overheat-
ing and damaging the catalytic converter.<

Flat Tire Monitor
The 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 sig-
nificantly 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 tire is detected and
reported on the basis of a deviation in cer-
tain speed ratios.
Functional requirement
So that the Flat Tire Monitor can learn the
correct inflation pressure, please perform
the following:
1.Check the inflation pressures in all tires
2.Compare with the inflation pressure
table on page 87 and correct if neces-
sary
3.Initialize the system.
Limits of the system
The Flat Tire Monitor cannot indicate
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, on the other
hand, there can be delays in detecting tire
pressure losses, and even system failure:
>When driving on snow-covered or slip-
pery 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 driv-
ing with snow chains fitted>When driving with a compact wheel, the
Flat Tire Monitor cannot operate.
Initializing the system
Perform the initialization immediately
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.Before the start of driving, start the
engine, but do not drive off
2.Press the button until the yellow indica-
tor lamp in the instrument cluster lights
up for a few seconds
3.Drive off.
It takes a few minutes until the Flat Tire
Monitor can detect and indicated a flat tire.
Do not initialize the system when driv-
ing with snow chains or with a com-
pact wheel.<
Flat tire
Indicator lamp
The symbol in the instrument clus-
ter lights up in yellow.
1.Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2.Identify damaged tire
If identification is not possible,
contact your BMW Sports Activity
Vehicle Center.<
3.Replace the damaged tire, refer to
Changing a wheel on page 103.

Things to remember when driving
80
Driving on bad roads
Your BMW X3 is at home on all paved and
unpaved roads. It combines all-wheel drive
with the advantages of a normal passenger
car.
Driving on unpaved terrain can cause
damage to the vehicle.<
When you are driving on bad roads, there
are a few points which you should strictly
observe Ñ for your own safety, for that of
your passengers, and for the safety of the
vehicle:
>Familiarize yourself with the vehicle
before you begin driving. Do not take
risks with the vehicle under any circum-
stances
>Always adapt the driving speed to the
road conditions. The more steep and
uneven the roadway 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 wish to drive on
uphill and downhill grades of this
nature, make sure beforehand that the
engine oil and coolant levels are near
the max mark, refer to pages 94 and 96
>For very steep downhill driving, use Hill
Descent Control HDC, refer to page 51.
Driving off is possible on upward
inclines of up to 33%.
The permitted side inclination is 50 %
>While driving, watch carefully for obsta-
cles such as rocks or holes. Try to avoid
these obstacles whenever possible
>Avoid that the body makes contact with
the ground, e.g. on the crests of hills
and bumpy roads
>Do not drive in water that is deeper than
20 in/50 cm. If you must drive through
water up to that depth, drive at a walk-
ing speed and do not stop.
After leaving the water, press on the
footbrake gently several times while
driving at a low speed. The brake appli-
cations will help to dry the brakes, thus
preventing a reduction in braking per-
formance caused by the moisture. 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, provided that traffic
conditions allow you to do so.
Please bear the following points in mind
after driving on poor roads, in order to pre-
serve the road safety of your BMW:
>Clean the heavy dirt from the body
>Clean mud, snow, ice and other materi-
als from the wheels and tires. Check the
tires for damage.

Washer fluid
Windshield and headlamp washer
system
Antifreeze agent for the washer sys-
tems 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 inaccessible to children.
Always observe the instructions for use
provided on the containers.<
We recommend that you mix the
washer ßuid before adding it to the
reservoir.<
Capacity:
approx. 6.9 US quarts/6.5 liters.
Fill with water and, if required, with an anti-
freeze additive according to manufac-
turer's recommendations.
Engine oil
Indicator lamp
Engine oil pressure
The indicator lamp lights up red:
Stop the vehicle immediately and
switch off the engine. Check the
engine oil level; top up as required. If the oil
level is correct: contact the nearest BMW
Sports Activity Vehicle Center.
Do not continue driving. The engine
could be damaged because of inade-
quate lubrication.<
Engine oil level
The indicator lamp lights up yellow
while driving:
The oil level is at the absolute mini-
mum. Add engine oil as soon as possible.
Until then, do not drive more than
approx. 30 miles/50 km.
The indicator lamp lights up yellow
after the engine is switched off:
Top up engine oil at the earliest
opportunity Ð when refueling.
Engine oil sensor
The indicator lamp lights up yellow
within 20 seconds after starting the
engine:
The oil level sensor is defective. Please
have it checked by a BMW Sports Activity
Vehicle Center.
Checking oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature
3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil should extend to between the
two marks on the dipstick.
As is the case with fuel economy, the rate
at which the engine uses oil is strongly
influenced by driving style and operating
conditions.
The oil quantity between the two marks of
the dipstick is approx. 1.1 US quarts/1 liter.

Under the engine hood

Checking coolant level and topping
up coolant
Check the coolant level with the engine
cold, approx. 687/206:
1.Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
2.The coolant level is correct if the upper
end of the red float bar is at least at the
same height as the top edge of the filler
neck, refer to arrow. The bar end may
only protrude by a maximum of i in/
2 cm, i.e. up to the second mark on the
float bar, refer also to sketch beside the
filler neck
3.If necessary, add coolant. Slowly add
coolant until the correct level is reached
Ð do not overfill.
Always observe all applicable rules
and regulations for environmental
protection when disposing of used anti-
freeze and anticorrosion agents.<
Brake system
Malfunction
Brake fluid
The warning lamp lights up red
despite the handbrake being
released: stop immediately.
The brake fluid in the reservoir has fallen to
below the minimum level. At the same time,
a considerably longer brake pedal travel
may be noticeable. Contact the nearest
BMW Sports Activity Vehicle Center.During continued driving increased
brake pedal pressure may be neces-
sary, and considerably longer braking dis-
tances may result. Please adapt your driv-
ing style accordingly.<

Brake pads
The indicator lamp comes on.
The brake pads have reached their
minimum pad thickness. See your
BMW Sports Activity Vehicle Center imme-
diately to have the pads replaced.
For your own safety: use only brake
pads that BMW has released for your
particular vehicle model. As BMW cannot
assess the suitability of other brake pads
for use on your vehicle, we are unable to
assume continued responsibility for the
vehicle's operating safety if non-approved
pads are installed.<

Maintenance
The BMW maintenance
system
The BMW maintenance system is designed
in such a way that it reliably ensures the
road safety and operating reliability of the
vehicle Ð keeping the cost for you as low as
possible.
Regular maintenance is not only required
for the safety of the vehicle, it also
improves the resale value.
Service Interval Display
The BMW Maintenance System takes the
driving conditions of the vehicle into
account when determining service inter-
vals:
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 high-
way travel.
The BMW maintenance system is divided
into engine oil service as well as Inspec-
tions I and II.
Determining the maintenance intervals
according to the actual loads on the vehi-
cle covers every kind of operating situa-
tion. However, even those who drive only
short distances Ð significantly less than
6,200 miles/10,000 km annually Ð should
have the engine oil changed at least every
2 years since oil deteriorates over time,
regardless of use.Brake fluid is hygroscopic: it absorbs
moisture from the atmosphere over
the course of time. To ensure that the brake
system continues to provide safe and reli-
able performance, remember to have the
brake fluid changed every two years at the
latest by a BMW Sports Activity Vehicle
Center, also refer to page 46 and to the
Service and Warranty Information Booklet
for US models or the Warranty and Service
Guide Booklet for Canadian models.<

Service Guide Booklet for Canadian
models
For detailed information on required main-
tenance items and the work involved,
please refer to the Service and Warranty
Information Booklet for US models or to the
Warranty and Service Guide Booklet for

Depending on operating conditions, it may
be advisable to have the body checked for
damage from rocks or gravel as a precau-
tion against corrosion.
BMW recommends that you have
your BMW Sports Activity Vehicle
Center perform the maintenance and
repair.
Check that the maintenance work is
recorded in the Service and Warranty
Information Booklet for US models or the
Warranty and Service Guide Booklet for
Canadian models. These entries will serve
as proof that the vehicle has received reg-
ular maintenance.<
