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.

Under the engine hood
Never attempt to perform any service
or repair operations on your vehicle
without the required professional technical
training. If you are unaware of the regula-
tions that need to be observed, BMW rec-
ommends that you have this work per-
formed at a BMW Sports Activity Vehicle
Center, as otherwise unqualified handling
of parts and materials can lead to safety
risk for vehicle occupants and other road
users.<
Hood
Unlocking
Pull the lever located under the left side of
the instrument cluster.
Opening
Press the release handle and open the
engine hood.
Closing
Let the engine hood fall from approx. 1 ft/
30 cm so that it can be heard to engage.
Observe the same precautions that
apply to all closing operations by
ensuring that the hood's travel range is
clear and unobstructed before allowing the
hood to fall into position.
If you see any signs that the hood is not
completely closed while driving your vehi-
cle, you should stop at once and close it
securely.<

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.

Do not fill beyond the upper mark on the
dipstick. Excess oil can damage the
engine.
Adding engine oil
While you should wait until the level has
dropped to just above the lower mark
before adding oil, you should never allow
the oil level to fall below this mark.
BMW engines are designed to oper-
ate without additives, and their use
could even lead to damage in some cases.
This also applies to the manual transmis-
sion, automatic transmission, the differen-
tial and the power steering system.<
Recommendation: have the oil change
conducted by your BMW Sports Activity
Vehicle Center.
Continuous exposure to used oil has
caused cancer in laboratory testing.
For this reason, any skin areas that come
into contact with oil should be thoroughly
washed with soap and water.
Always store oils, grease and similar mate-
rials so that they are inaccessible to chil-
dren. Comply with warning labels and
information on containers.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used oil.<
Approved engine oils
The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. Based on exten-
sive testing, BMW has approved only cer-
tain engine oils.
Use only approved BMW High Perfor-
mance Synthetic Oil.If you are unable to obtain BMW High Per-
formance Synthetic Oil, you can add small
amounts of another synthetic oil between
oil changes. Use only oils with the API SH
specification or higher.
Ask your BMW Sports Activity Vehicle
Center for details concerning the spe-
cific BMW High Performance Synthetic Oil
or synthetic oils which have been
approved.<
You can also call BMW of North America at
1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this informa-
tion.
Viscosity ratings
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class
depends on the climate conditions in the
area where you typically drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
>These oils may be used for driving in all
ambient temperatures.
Coolant
Indicator lamp
The indicator lamp lights up:
Coolant level is too low; top up at
the earliest opportunity.
Do not add coolant to the cooling sys-
tem when the engine is hot. Escaping
coolant can cause burns.
Antifreeze and anticorrosion agents are
hazardous to health. You should always
store them in their original containers and
in a location which is inaccessible to chil-
dren. Antifreeze and anticorrosion agents
are flammable. Therefore, do not pour over
hot engine parts, as otherwise they could
catch fire and cause burns. Always observe
the instructions for use provided on the
containers.<

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.<
Warning lamp for Canadian models.
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.<
For additional information on the brake sys-
tem, refer to page 77.

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 and Warranty Information

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
Canadian models.
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.<

Laws and regulations
California Proposition 65
Warning
California laws require us to state the fol-
lowing warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of California
to cause cancer and birth defects and
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm. Battery posts, terminals
and related accessories contain lead and
lead compounds. Wash your hands after
handling. Used engine oil contains chemi-
cals that have caused cancer in laboratory
animals. Always protect your skin by wash-
ing thoroughly with soap and water.<
OBD connector
The interface socket for the Onboard Diag-
nostic is located on the left of the driver's
side at the bottom of the instrument cluster
and under a cover. The cover has the let-
ters OBD on it.
The most important components for the
composition of the emissions can be
checked by a device across this interface. 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 lamp 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 opportu-
nity.
If the indicator lamp blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the nearest
BMW Sports Activity Vehicle Center imme-
diately. Severe engine misfiring over even a
short period of time can seriously damage
emission control system components,
especially the catalytic converter.

If the fuel filler cap is not on tight
enough, the OBD system can detect
leaking vapor and the indicator lamp will
light up. If the fuel filler cap is then tight-
ened, the indicator lamp will usually go out
after a short period of time.<

Front passenger side
Before replacing the bulb, remove the res-
ervoir for the windshield washing system
from the bracket. To do so, loosen the bolt,
refer to arrow, and place the reservoir to
one side.
Bear in mind that the windshield
washing system reservoir is heavy. If
you do not, injuries or damage to the vehi-
cle can occur.<
For bulb replacement procedure, refer to
Driver's side.
Xenon lamps*
The service life of these bulbs is very long
and the probability of a failure is very low,
provided that they are not switched on and
off an unusual number of times. If one of
these bulbs should nevertheless fail, it is
possible to continue driving with great cau-
tion using the fog lamps, provided traffic
laws in your area do not prohibit this.
To avoid risk of potentially fatal inju-
ries: owing to the extremely high volt-
ages at which these units operate, service
work should always be entrusted to quali-
fied personnel.<
