2017 BMW X3 inflation pressure

LoadingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Information WARNING
High gross weight can overheat the tires,
damage them, and cause a sudden drop in tire
inflation pressure. There is risk of an accident.
Pay attention to the permitted load capacity of
the tires and never exceed the permitted gross
weight.◀
WARNING
Loose objects or devices with a cable
connection to the vehicle, e.g., mobile phones,
can be thrown into the vehicle's interior while
driving, e.g.,in the event of an accident or dur‐
ing braking and evasive maneuvers. There is a
a risk of injury. Secure loose objects or devices
with a cable connection to the vehicle in the
vehicle's interior.◀
ATTENTION
Fluids in the cargo area can cause dam‐
age. There is a risk of damage to property.
Make sure that no fluids leak in the cargo
area.◀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 the
vehicle 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.Seite 186Driving tipsLoading186

respective features 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.
Carrying out certain measures, such as a mod‐
erate driving style and regular maintenance,
can influence fuel consumption and the envi‐
ronmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Remove roof-mounted 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
thereby reduces the range.
Tires
General information Tires can affect fuel consumption in various
ways, e.g., tire size may influence fuel con‐
sumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
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 immediately
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 quickest way of warming the cold
engine up to 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 proactively reduces fuel
consumption.Seite 189Saving fuelDriving tips189

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 tire inflation pressure
WARNING
A tire with low or missing tire inflation
pressure impacts handling, such as steering
and braking response. There is risk of an acci‐
dent. Regularly check the tire inflation pres‐
sure, and correct it as needed, e.g., twice a
month and before a long trip.◀
Tires have a natural, consistent loss of tire in‐
flation pressure.
Tires heat up while driving, and the tire infla‐
tion pressure increases along with the tire's
temperature. The tire inflation pressure speci‐
fications relate to cold tires or tires with the
ambient temperature.
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.
The displays of inflation devices may under-
read by up to 0.1 bar/2 psi.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire
Monitor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.
Tire inflation pressure specifications
The tire inflation pressure table, refer to
page 206, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pres‐
sure values apply to tire sizes approved by the
manufacturer of the vehicle for the vehicle
type.
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 206, and adjust as necessary.

Tire treadSummer tires
Do not drive with a tire tread depth of less than
0.12 inches/3 mm.
There is an increased danger of hydroplaning if
the tire tread depth is less than 0.12 in‐
ches/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 inches/4 mm.
Below a tread depth of 0.16 inches/4 mm, tires
are less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in‐
ches/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
General information
Inspect your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Information Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles
can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Indications of tire damage or other vehicle mal‐
functions:▷Unusual vibrations while driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
Damage can, e. g., be caused by driving over
curbs, road damage, or similar things.
WARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is risk of an accident. If tire dam‐
age is suspected while driving, immediately re‐
duce speed and stop. Have wheels and tires
checked. For this purpose, drive carefully to
the nearest dealer’s service center or another
qualified service center or repair shop. Have
vehicle towed or transported as needed.◀
WARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is risk of an accident. Do not re‐
pair damaged tires, but have them replaced.◀
Changing wheels and tires
Mounting Have mounting and wheel balancing carriedout by a dealer’s service center or another
qualified service center or repair shop.
Wheel and tire combination
You can ask the dealer’s service center or an‐
other qualified service center or repair shop
about the right wheel/tire combination and
wheel rim versions for the vehicle.

shop. After rotating, check the tire pressure
and correct if needed.
Rotating the tires between the axes is not per‐
missible on vehicles with different tire sizes or
rim sizes on the front and rear axles.
Storage
Store 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 consist of tires that are self-sup‐
porting, to a limited degree, and possibly spe‐
cial rims.
The support of the sidewall allows the tire to
remain drivable to a restricted degree in the
event of a tire inflation pressure loss.
Follow the instructions for continued driving
with a flat tire.
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
A dealer’s service center will be glad to answer
additional questions at any time.
Repairing a flat tire
Safety measures▷Park the vehicle as far away as possible
from passing traffic and on solid ground.▷Switch on the hazard warning system.▷Secure the vehicle against rolling away by
setting the parking brake.▷Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.▷Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.▷If necessary, set up a warning triangle at an
appropriate distance.
Mobility System
The concept
With the Mobility System, minor tire damage
can be sealed temporarily to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the
inside.
The compressor can be used to check the tire
inflation pressure.
Information
▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.▷Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 in/4 mm or more.▷Contact a dealer’s service center or an‐
other qualified service center or repair
shop if the tire cannot be made drivable.▷If possible, do not remove foreign bodies
that have penetrated the tire.Seite 212MobilityWheels and tires212
Online Edition for Part no. 01 40 2 969 976 - II/16

▷Pull the speed limit sticker off the sealant
container and apply it to the steering
wheel.▷The use of a sealant can damage the TPM
wheel electronics. In this case, have the
electronics checked at the next opportu‐
nity and have them replaced if needed.
DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of
the vehicle. There is danger to life. Keep the
exhaust pipe free and ensure sufficient ventila‐
tion.◀
Storage
The Mobility System is located under the cargo floor panel.
