2013 BMW X3 tire pressure

LoadingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Hints Overloading the vehicle
To avoid exceeding the approved carry‐
ing capacity of the tires, never overload the ve‐
hicle. Overloading can lead to overheating and
increases the rate at which damage develops
inside the tires. This could result in a sudden
loss of tire inflation pressure.◀
No fluids in the trunk
Make sure that fluids do not leak into the
trunk; otherwise, the vehicle may be dam‐
aged.◀
Determining the load limit1.Locate the following statement on your ve‐
hicle’s placard:▷The combined weight of occupants
and cargo should never exceed XXX kg
or YYY lbs. Otherwise, damage to thevehicle and unstable driving situations
may result.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 kilograms or
YYY pounds.4.The resulting figure equals the available
amount of cargo and luggage load ca‐
pacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 400 lbs: 1,000 lbs minus 600 lbs =
400 lbs.5.Determine the combined weight of lug‐
gage and cargo being loaded on the vehi‐
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
Load
The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.

Saving fuelVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
General information Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
The implementation of certain measures, driv‐
ing style and regular maintenance can have an
influence on fuel consumption and on the envi‐
ronmental impact.
Remove unnecessary cargoAdditional weight increases fuel consumption.
Remove attached parts
following use
Remove auxiliary mirrors, roof or rear luggage
racks which are no longer required following
use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
raises fuel consumption.
Tires General information
Tires can affect fuel consumption values in
various ways, for instance fuel consumption
can be influenced by the size of the tires.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire infla‐
tion pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.Seite 150Driving tipsSaving fuel150

Wheels and tiresVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Tire inflation pressure Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the pressure
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours. When the
tires are warm, the tire inflation pressure is
higher.
Check the tire inflation pressure regularly
Regularly check the tire inflation pres‐
sure, and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
After correcting the tire inflation pressure:
▷Reinitialize the Flat Tire Monitor.▷Reinitialize the Tire Pressure Monitor.Pressure specifications The tire inflation pressure table, refer to
page 160, contains all pressure specifications
for the specified tire sizes at the ambient tem‐
perature. Pressure specifications apply to ap‐
proved tire sizes and recommended tire
brands. This information can be obtained from
your service center.
To identify the correct tire inflation pressure,
please note the following:▷Tire sizes of your vehicle.▷Maximum permitted driving speed.
Tire inflation pressures up to
100 mph/160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 160, and adjust as necessary.
These pressure values can also be found on
the tire inflation pressure label on the driver's
door pillar.
Maximum permissible speed
Do not exceed 100 mph/160 km/h; other‐
wise, tire damage and accidents may result.◀

Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
Winter tires
The manufacturer of your vehicle recommends
winter tires for winter roads or at temperatures
below +45 ℉/+7 ℃.
Although so-called all-season M+S tires do
provide better winter traction than summer tires, they do not provide the same level of per‐
formance as winter tires.
Maximum speed of winter tires If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then display a corresponding sign in the field
of vision. You can obtain this sign from the tire
specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the winter tires; otherwise, tire damage and ac‐
cidents can occur.◀
Run-flat tires If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in the
case of a flat tire. Your service center will be
glad to advise you.
Rotating wheels between axles
The manufacturer of your vehicle advises
against switching wheels between the front
and rear axles.
This can impair the handling characteristics.
StorageStore wheels and tires in a cool, dry place with
as little exposure to light as possible.Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Run-flat tires
Label
RSC label on the tire sidewall.
The wheels are composed of special rims and
tires that are self-supporting, to a limited de‐
gree.
The support of the sidewall allows the tire to
remain drivable to a restricted degree in the
event of a pressure loss.
Continued driving with a damaged tire, refer to
page 102.
Continued driving with a damaged tire, refer to
page 99.
