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.<

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.

Break-in procedures
To ensure that your vehicle provides maxi-
mum economy throughout a long service
life, we request that you observe the fol-
lowing instructions:
Engine and differential
Up to 1,200 miles/2,000 km:
During this initial period you should attempt
to avoid constant, steady-state operation
and vary both vehicle and engine speeds
as often as possible. Until the break-in
period has been completed you should
also refrain from exceeding the following:
>4,500 rpm or 100 mph/160 km/h.
Always obey all official speed limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the kick-
down point.
Once you have driven 1,200 miles/
2,000 km, the engine and vehicle speeds
can be gradually increased.
You should also comply with these break-in
procedures should the engine or one of the
differentials be replaced later in the course
of the vehicle's service life.
Tires
Due to technical factors associated with
their manufacture, tires do not achieve their
full traction 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
limits.
When the vehicle is operated on wet
or slushy roads, a wedge of water
may form between the tire and the road
surface. This phenomenon is referred to as
hydroplaning and can lead to partial or
complete loss of traction, vehicle control
and braking effectiveness. Reduce your
speed on wet roads.<
Brake system
Approx. 300 miles/500 km must elapse
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 standstill Ð at a traffic signal, for
instance; use caution 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 set.
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 Ð e.g.
by towing Ð substantially higher levels of
pedal force will be required to brake the
vehicle.<
Clutch
The function of the clutch is also only at its
optimized level after a distance driven of
approx. 300 miles/500 km. During this
break-in period, engage the clutch gently.
General driving notes
High temperatures
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Do not remove
the heat shields installed adjacent to vari-
ous sections of the exhaust system, and
never apply undercoating to them. When
driving, standing at idle and while 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, and with it the risk of serious prop-
erty damage as well as personal injury.<
Parking the vehicle
Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed
water under the vehicle are thus normal.
Before driving into the car wash
Fold in the exterior mirrors, refer to
page 31, as otherwise they could be dam-
aged due to the width of the vehicle.
Deactivate the rain sensor as otherwise
damage could result from undesired wiper
activation, refer to page 42.
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 surface. This phenomenon is referred
to as hydroplaning, and is characterized by
a partial or complete loss of contact
between tires and road surface, ultimately
undermining your ability to steer and brake
the vehicle.<
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 systems
and the transmission may be damaged.<
Safe braking
Emergency stops
The best way to brake is to apply maximum
pressure to the brake pedal during emer-
gency Ð panic stops. Since the vehicle
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. Do not drive with your foot resting on
the brake pedal. Otherwise, even light
but consistent pedal pressure can lead to
high temperatures, brake wear and possi-
bly even brake failure.<
Wet conditions
While driving in wet conditions and in
heavy rain, it is a good idea to 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 which is gener-
ated by the brake applications helps to dry
the brake pads and rotors. The required
braking force will then be available when
you need it.
On a grade
You can retain full and unimpaired braking
efficiency by downshifting to a gear in
which only minimal brake applications are
needed when descending long or steep
downhill stretches.
You can further enhance the engine's brak-
ing effect by selecting a lower gear in the
automatic transmission's manual mode,
downshifting as far as first gear on
extremely steep stretches, refer to
page 38. This strategy helps you avoid
placing excessive loads on the brake sys-
tem.
During slower downhill driving, use the Hill
Descent Control HDC, refer to page 51.
Never drive with the clutch pressed,
with the transmission in Neutral or
with the engine switched off, as otherwise
there is no engine braking when the trans-
mission is in Neutral, and no power-assist
for brakes and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion
When the vehicle is driven only occasion-
ally, during extended periods when the
vehicle is not used at all, and in operating
conditions where brake applications are

Things to remember when driving
78 less frequent, there is an increased ten-
dency 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 pul-
sating effect that even extended applica-
tion will fail to cure.
Cargo loading
To avoid loading the tires beyond
their approved carrying capacity,
never overload the vehicle. Overloading
can lead to overheating and increases the
rate at which damage develops inside the
tires. The ultimate result can assume the
form of a sudden air loss.<
Determining the load limit
1.Locate the following statement on the
driver's door pillar:
The combined weight of occu-
pants and cargo should never
exceed XXX lbs or YYY kg. Failure to
observe this can compromise your
vehicle's driving stability and cause
vehicle damage.<
2.Determine the combined weight of the
driver and passengers that will be riding
in your vehicle
3.Subtract the combined weight of the
driver and passengers from XXX
pounds or YYY kilograms4.The resulting figure equals the available
amount of cargo and luggage load
capacity.
For example, if the XXX amount equals
1,400 lbs and there will be five 150-lbs
passengers in your vehicle, the amount
of available cargo and luggage load
capacity is 650 lbs:
1,400 lbs minus 750 lbs = 650 lbs
5.Determine the combined weight of lug-
gage and cargo being loaded on the
vehicle. That weight should never
exceed the available cargo and luggage
load capacity calculated in Step 4
6.If your vehicle will be towing a trailer,
part of the load from your trailer will be
transferred to your vehicle. Consult the
manual for transporting a trailer to
determine how this may reduce the
available cargo and luggage load
capacity of your vehicle.
Load
The permitted load is the total of the weight
of occupants and cargo/luggage. The
greater the weight of occupants, the less
cargo/luggage can be transported.

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.

Tire inflation pressure
Information for your safety
It is not merely the tire's service life, but
also driving comfort and Ð to a great extent
Ð driving safety that depend on the condi-
tion of the tires and the maintenance of the
specified tire pressure.
Check the tire inflation pressure regu-
larly and correct it if necessary,
including compact wheel: at least every
two weeks and before beginning a longer
trip. If you fail to observe this precaution
you may be driving on tires with incorrect
tire pressures, a condition that cannot only
compromise your vehicle's driving stability,
but also lead to tire damage and the risk of
an accident.
Do not drive with a depressurized, i.e. flat
tire. A flat tire will seriously impair your
vehicle's handling and braking response.
Attempts to drive on a flat tire can lead to
loss of control over the vehicle.<
Checking the pressure
Only check tire inflation pressure when the
tires are cold. That means after a maximum
of 1.25 miles/2 km driving or when the
vehicle has been parked for at least 2
hours. When tires are warm, the tire infla-
tion pressure increases.
After correcting the inflation pressure(s),
always reinitialize the Flat Tire Monitor,
refer to page 53.
Checking inflation pressure
The inflation pressures for your standard
tires can be seen on the door pillar when
you open the driver's door.
After correcting the inflation pres-
sure(s), always reinitialize the Flat Tire
Monitor, refer to page 53.<
Inflation pressure for other tire sizes
The table below provides all the correct
inflation pressures for the specified tire
sizes at ambient temperature.
For correct identification of the right
tire inflation pressure for your tires,
observe the specifications for the corre-
sponding tire size.<
