66 The corresponding memory button1 is now
programmed with the signal of the original
hand-held transmitter.
You can use the system when the engine is run-
ning or when the ignition is switched on.
If the system cannot be operated after
repeated programming, check whether
the original hand-held transmitter uses an alter-
nating-code system. To do so, either read the
instructions of the original hand-held transmit-
ter or press and hold down the programmed
memory button 1 of the integrated universal
remote control. If the LED2 on the integrated
universal remote control flashes rapidly for a
short time then lights up for approx. 2 seconds,
this indicates that the original hand-held trans-
mitter uses an alternating-code system. In the
case of an alternating-code system, program
the memory buttons 1 as described in the sec-
tion below on alternating-code transmitters.<
Alternating-code transmitters
Consult the operating instructions of the unit
you wish to set when programming the univer-
sal remote control. You will find information
there on the possibilities for synchronization.
When programming hand-held transmitters
that employ an alternating code, please follow
these additional instructions:
Programming will be easier with the aid of
a second person.<
1.Park your vehicle within the range of the
remote-controlled equipment.
2.Program the integrated universal remote

Things to remember when driving
Breaking-in
Moving parts should be allowed to adjust to one
another. To ensure that your vehicle provides
maximum economy throughout a long service
life, we request that you observe the following
instructions.
Engine and differential
Always obey all official speed limits.
For the first 1,200 miles/2,000 km
Drive at varying engine and driving speeds, but
do not exceed 4,500 rpm or 100 mph / 160 km/h
in the process.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kick-down point.
After 1,200 miles/2000 km
Engine and road speed can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. For this reason, drive with extra care
during the initial 200 miles/300 km.
Obey your local and state maximum speed lim-
its.
When the vehicle is operated on wet or
slushy roads, a wedge of water may form
between the tire and the road surface. This phe-
nomenon is referred to as hydroplaning and can
lead to partial or complete loss of traction, vehi-
cle control and braking effectiveness. Reduce
your speed on wet roads.<
Brake system
Your vehicle must travel approx. 300 miles/
500 km before the brake pads and rotors
achieve the optimal pad-surface and wear patterns required for trouble-free operation and
long service life later on.
To break in the separate handbrake drums,
apply the handbrake lightly when coasting to a
stop – at a traffic signal, for instance; use cau-
tion to avoid posing a danger to other road
users.
To avoid corrosion, repeat this procedure from
time to time.
The brake lamps do not come on when the
handbrake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the vehicle
with the engine off – e.g., by towing – substan-
tially higher levels of pedal force will be required
to brake the vehicle.<
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following component replacements
Follow the break-in sequence again if compo-
nents addressed above must be replaced due
to subsequent driving.
General driving notes
Close the liftgate
Operate the vehicle only when the liftgate
is completely closed; otherwise, exhaust
fumes could enter the interior of the vehicle.<
If special circumstances should make it abso-
lutely necessary to operate the vehicle with the
liftgate open:

1.Close all windows and the panorama glass
sunroof.
2.Greatly increase the air supply of the air
conditioning system or automatic climate
control, refer to page60 or63.
Hot exhaust system
High temperatures occur in the exhaust
system of every vehicle. Do not remove
the heat shields installed adjacent to various
sections of the exhaust system, and never apply
undercoating to them. When driving, standing
at idle, and parking, take care to avoid possible
contact between the 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.<
Mobile communications devices in
vehicle
BMW does not recommend using mobile
communications devices, e.g. mobile
phones, on the interior of the vehicle without a
direct connection to an outside antenna. Other-
wise, the vehicle electronics and mobile com-
munications device can affect each other. In
addition, there is no assurance that the radia-
tion which results during transmission will be
dissipated from the vehicle interior.<
Interior and exterior mirror,
automatically dimming*
Two photocells are used to control the auto-
matically dimming interior and exterior mirrors.
One is integrated into the mirror glass, the other
is located on the back of the mirror.For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach any kind of sticker to the windshield
in front of the mirror, either.
When the vehicle is parked
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are therefore normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page30;
otherwise, they could be damaged due to the
width of the vehicle.
Deactivate the rain sensor; otherwise, damage
could result from undesired wiper activation,
refer to page40.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between tires and
road surface, ultimately undermining your abil-
ity to steer and brake the vehicle.<
The danger of hydroplaning increases as tire
tread depth decreases, also refer to Minimum
tread depth on page89.
Driving through water
Do not drive through water on the road if it
is deeper than 20 in/50 cm, and then only
at walking speed. Otherwise, the vehicle's
engine, the electrical system, and the transmis-
sion may be damaged.<
Using handbrake on inclines
Do not hold the vehicle in place on slopes
by slipping or riding the clutch, use the
handbrake instead. Otherwise, greater clutch
wear will result.<

Things to remember when driving
78
Safe braking
Your BMW is equipped with ABS as standard
equipment. In situations in which it is required, it
is best to apply the brakes fully. Since the vehi-
cle maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.
Pulsation at the brake pedal combined with
sounds from the hydraulic circuits indicates to
the driver that ABS is in its active mode.
Wet roads
On wet roads or in heavy rain, briefly apply light
pressure to the brake pedal every few miles.
Watch traffic conditions to ensure that this
maneuver does not endanger other road users.
The heat that is generated by the brake applica-
tions helps to dry the brake pads and rotors.
The full braking force will then be available
when you need it.
Hills
To prevent overheating and reduced effi-
ciency of the brake system, drive long or
steep downhill grades in the gear in which the
least braking is required. Otherwise, even light
but continuous pressure on the brake can lead
to high temperatures, brake wear and possibly
even brake failure.<
The braking action of the engine can be further
intensified by downshifting, all the way down to
first gear if need be. This strategy helps you
avoid placing excessive loads on the brake sys-
tem. Downshifting in manual mode of automatic
transmission, refer to page39. When descend-
ing hills slowly, use HDC Hill Descent Control,
refer to page49.
Never drive with the clutch depressed,
with the transmission in neutral, or with
the engine switched off; otherwise, you will
have neither the braking action of the engine or
nor its power assistance to the brakes or steer-
ing.
Never allow floor mats, carpeting, or other arti-
cles to protrude into the area around the brake
or accelerator pedals and obstruct their move-
ment.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimal
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.<
Determining load limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, the vehicle
may be damaged and unstable driving con-
ditions may result.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.

Things to remember when driving
80 Please read the information provided with
the heavy-duty cargo straps.
Always position and secure cargo as
described above. If you do not, it can
endanger the passengers during braking or
evasive maneuvers.
Use only the lashing eyes, refer to page73, to
fasten the heavy-duty cargo straps; otherwise,
the heavy-duty cargo straps could loosen or the
vehicle could be damaged.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page116, as excessive loads can pose a
safety hazard and may also place you in viola-
tion of road safety laws.
You should never transport heavy or hard
objects unsecured in the passenger compart-
ment, as they could be thrown about and pose a
safety hazard to the vehicle's occupants during
abrupt braking or evasive maneuvers.<
Roof-mounted luggage rack*
A special rack system is available as an optional
accessory for your BMW. Please observe the
information contained in the installation instruc-
tions.
Loading luggage rack
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
its handling and steering response. You should
therefore always remember not to exceed the
approved roof load capacity, the approved
gross vehicle weight, or the axle loads when
loading the rack.
These specifications can be found under
Weights on page116.
Make sure that the load is evenly distributed,
and that it does not extend outward beyond the
limits of the loading surface. Always stow the
heaviest pieces at the bottom. Be sure that ade-
quate clearance is maintained for raising the
glass sunroof and that objects do not project
into the opening path of the liftgate.Secure roof-mounted cargo correctly and
securely to prevent it from shifting or falling off
while you drive.
Drive smoothly. Avoid sudden acceleration and
braking maneuvers. Take corners gently.
Driving on poor roads
Your 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 poor roads, there are a
few points which you should strictly observe –
for your own safety and that of your passengers,
as well as to protect the vehicle:
>Familiarize yourself with the vehicle before
you begin driving. Do not take risks with the
vehicle under any circumstances.
>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
pages94 and95.
>When descending very steep hills, use
HDC Hill Descent Control, refer to page49.
It is possible to start off on inclines of up
to 32 %.
The permitted side tilt is 32 %.
>While driving, watch carefully for obstacles
such as rocks or holes. Try to avoid these
obstacles whenever possible.
>Avoid having the body make contact with
the ground, e.g. on the crests of hills and
bumpy roads. The ground clearance of the
vehicle is a maximum of approx. 8.0 in/
20 cm. Please be aware that the ground
clearance can vary depending on the load
and operating conditions of the vehicle.

The warning lamp
* lights up.
The fuel cap is not properly closed or is
missing. Check whether the fuel cap is
properly closed.
Manually releasing fuel filler door
In the event of an electrical malfunction in the
system, you can release the fuel filler door man-
ually:
1.Open the cover flap in the cargo area on the
right-hand side panel, refer to page72.
2.Pull the green button. The fuel filler flap is
released.
Always observe all applicable precautions
and regulations when handling fuels.
Never carry spare fuel containers in your vehi-
cle. Whether empty or full, these containers can
leak, cause an explosion, and lead to fire in the
event of a collision.<
Observe the following when refueling
When handling fuels, comply with all
applicable safety precautions posted at
the service station.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid lifting the filler
nozzle while filling the tank; otherwise, this can
result in:
>premature pump shutoff
>reduced efficiency in the fuel-vapor recov-
ery system

Never attempt to continue driving until
the tank is completely empty; this can
negatively affect engine function and can dam-
age the vehicle.<
Fuel specifications
Never use leaded gasoline. Otherwise,
you will cause permanent damage to your
catalytic converter.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with a
lower AKI rating. The minimum AKI rating is 87.
If you use gasoline with this minimum AKI rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10 % ethanol or other
oxygenates with up to 2,8 % oxygen by weight,
that is, 15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
stalling, starting and drivability problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems that
you suspect could be related to the fuel you are
using, we recommend that you respond by
switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<

works according to BMW repair procedures
with correspondingly trained personnel.
Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If you are unable to obtain BMW High Perfor-
mance Synthetic Oil, you can add small
amounts of another synthetic oil in between oil
changes. Only use oils with the API SH specifi-
cation or higher.
Ask your BMW Sports Activity Vehicle
Center for more details concerning BMW
High Performance Synthetic Oil or other
approved synthetic oils.<
You can also call BMW of North America at
1-800-831-1117 or visit website
www.bmwusa.com to obtain this information.
BMW engines are designed to operate
without additives, and their use could
even lead to damage in some cases.<
Viscosity classes
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 belong to SAE classes
5W-40 and 5W-30.<
These oils can be used for driving in all ambient
temperatures.
Coolant
Warning lamp
The warning lamp lights up: coolant
level is too low; top off at the next
opportunity.Do not open 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 suit-
able for your BMW. Ask your BMW Sports
Activity Vehicle Center for suitable additives.
Only use suitable additives; otherwise,
engine damage may result. The additives
present a health hazard.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
3.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 pro-
trude by a maximum of ιin/2 cm, i.e. up to
the second mark on the float bar, refer also
to drawing beside the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Screw on the cap and tighten snugly.
6.Have the reason for the coolant loss cor-
rected as soon as possible.
