LoadingVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
General information 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 cargo area
Make sure that fluids do not leak into the
cargo area; 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 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 4.6.If your vehicle will be towing a trailer, load
from your trailer will be transfered to your
vehicle. Consult the manual for transport‐
ing a trailer to determine how this may re‐
duce the available cargo and luggage load
capacity of your vehicle.Seite 134Driving tipsLoading134

Saving fuelVehicle equipmentThis chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
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, refer to
page 245, can have an influence on fuel con‐
sumption and on the environmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Remove unneeded auxiliary mirrors, roof or
rear luggage racks after use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Closing the windows and
panoramic glass sunroof
Driving with the panoramic glass sunroof and
windows open results in increased air resist‐
ance and raises fuel consumption.
Check the tire inflationpressure regularly
Check and, if necessary, correct the tire infla‐
tion pressure, refer to page 230, 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.
Avoid high engine speeds
Driving at a low engine speed reduces fuel
consumption and minimizes wear.Seite 137Saving fuelDriving tips137

Tire inflation pressure Safety information
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres‐
sure.
Checking the pressure Tires naturally lose pressure uniformly across
all four tires.
Only check the tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving 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.◀Tires warm up during driving and the tire infla‐
tion pressure increases as the temperature
rises. The tire inflation pressure specifications
apply to cold tires or tires at ambient tempera‐
ture.
Only check the tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle
has been parked for at least 2 hours.
The values displayed by tire inflation stations
may be up to 0.1 bar, 2 psi too low.
For the Flat Tire Monitor: after adjusting the
tire inflation pressure to a new value, reinitialize
the Flat Tire Monitor, refer to page 91.
For the Tire Pressure Monitor: after adjusting
the tire inflation pressure to a new value, reset
the Tire Pressure Monitor, refer to page 94.
Pressure specifications The tables below provide all the correct infla‐
tion pressures for the specified tire sizes at
ambient temperature.
The inflation pressures apply to the tire sizes
approved and tire brands recommended by
BMW; a list of these is available from your
service center.
For correct identification of the right tire infla‐
tion pressures, observe the following:▷Tire sizes of your vehicle.▷Maximum allowable driving speed.
Tire inflation pressures for driving up
to 100 mph or 160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column for traveling speeds up to 100 mph/
160 km/h to achieve optimum driving comfort.

Online Edition for Part no. 01 40 2 957 353 - X/14

These tire inflation pressures can also be
found on the driver's side door pillar when the
driver's door is open.
Do not exceed the maximum permissible
speed
The permissible maximum speed for these tire
inflation pressures is 100 mph/160 km/h. Do
not exceed this speed or else there is a risk of
tire damage and accidents.◀
Tire inflation pressures for driving
above 100 mph or 160 km/h
Adjust the tire inflation pressures
To drive at maximum speeds in excess of
100 mph/160 km/h, adjust pressures to the re‐
spective tire inflation pressures listed on the
following pages in the column for traveling
speeds including those exceeding 100 mph or
160 km/h. Otherwise, tire damage and acci‐
dents could occur.◀
Observe all national and local maximum speed
limits; otherwise, violations of the laws could
occur.

2313: tire age
Tire age
The tire manufacturing date is contained in the
tire identification mark: DOT ... 2313 means
that the tire was manufactured in the
week 23 of 2013.
BMW recommends that you replace all tires af‐
ter 6 years at most, even if some tires may last
for 10 years.Seite 235Wheels and tiresMobility235
Online Edition for Part no. 01 40 2 957 353 - X/14

Incorrect wheel and tire combinations impair
the function of a variety of systems such as
ABS or DSC.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐
figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
Approved wheels and tires
The manufacturer of your vehicle recom‐
mends that you use only wheels and tires that
have been approved for your particular vehicle
model.
For example, despite having the same official
size ratings, variations can lead to body con‐
tact and with it, the risk of severe accidents.
The manufacturer of your vehicle cannot eval‐
uate non-approved wheels and tires to deter‐
mine if they are suited for use, and therefore
cannot ensure the operating safety of the vehi‐
cle if they are mounted.◀
Wheels with electronics for TPM Tire
Pressure Monitor
When mounting new tires or changing from
summer to winter tires or vice versa, only use
wheels with TPM electronics; otherwise, the
Tire Pressure Monitor will not be able to detect
a flat tire, refer to page 93. Your service center
will be glad to advise you.Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
With proper use, these tires meet the highest
standards for safety and handling.
Retreaded tires The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
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
For your own safety, only use run-flat tires.
Your service center will be glad to advise you.
Rotating wheels between axlesThe manufacturer of your vehicle advises
against swapping wheels between the front
and rear axles.
This can impair the handling characteristics.
Rotating the tires is not permissible when us‐
ing different types of tires.
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 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.
Driving with a damaged tire:▷Flat Tire Monitor FTM, refer to page 91▷Tire Pressure Monitor TPM, refer to
page 93
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.
Your service center will be glad to advise you.
Snow chains
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your service center for
more information.
Snow chains must be mounted in pairs and on the rear wheels only.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h when using snow chains.
Do not initialize the Flat Tire Monitor if snow
chains are mounted; otherwise, the instrument
might issue an incorrect reading.
When driving with snow chains, it can be bene‐
ficial to temporarily activate DTC, refer to
page 98.
