Sitting safely
The ideal sitting position can make a vital
contribution to relaxed driving that is as
fatigue-free as possible. The sitting posi-
tion plays an important role together with
the safety belts and airbags in an accident.
To ensure that the safety systems operate
with optimized efficiency, we strongly urge
you to observe the instructions contained
in the following section.
For additional information on transporting
children safely, refer to page 56.
Sitting safely with airbags
Always maintain an adequate dis-
tance between yourself and the air-
bags. Always hold the steering wheel by
its rim with hands at the 9 o'clock and
3 o'clock positions, to minimize the risk of
injuries to your hands and arms in the event
of airbag deployment.
No one and nothing is to come between the
airbags and the seat occupant.
Do not use the cover of the front airbag on
the front passenger side as a storage area.
Make sure that the front passenger is cor-
rectly seated and does not rest feet or legs
on the instrument panel, otherwise leg inju-
ries can occur if the knee and front airbag
are triggered.
Never let an occupantÔs head rest near or
on a side airbag because the inflating air-
bag could cause a serious or fatal injury.<
Even if you adhere to all the instructions,
injuries resulting from contact with airbags
cannot be fully excluded, depending on the
circumstances. The ignition and inflation
noise may provoke a mild Ð usually tempo-
rary Ð hearing loss in extremely sensitive
individuals.
For airbag locations and additional infor-
mation on airbags, refer to page 97.
Sitting safely with safety belts
Fasten your safety belt before starting any
trip. Although airbags enhance safety by
providing added protection, they are not a
substitute for safety belts.
Your vehicle has five seats that are all
equipped with a safety belt.
At all times, occupants should sit
upright and be properly restrained Ð
infants and small children in appropriate
child-restraint systems; larger children and
adults using the safety belts.
Expectant mothers should always wear
their safety belts, taking care to position
the lap belt against the lower hips, where it
will not exert pressure against the abdomi-
nal area.
Never allow more than one person to wear
a single safety belt. Never allow infants or
small children to ride in a passenger's lap.
Do not route the belt across your neck, or
run it across sharp edges. Be sure that the
belt does not become caught or jammed.
Avoid twisting the belt while routing it firmly
across the hips and shoulder. Do not allow
the belt to rest against hard or fragile
objects. Otherwise, in the event of a frontal
impact, a loose lap belt could slide over
your hips, leading to abdominal injury.
Avoid wearing clothing that prevents the
belt from fitting properly and pull the lap
belt periodically to readjust the tension
across your shoulder in order to avoid a
reduction in the retention effect of the
safety belt.<
For instructions on operating safety belts,
refer to page 49.

sity with which you are applying your
brakes to drivers of following vehicles.
The display consists of two stages:
>Normal braking:
The brake lamps in the tail lamp assem-
blies and the high-mount brake lamp on
the rear tray light up during braking
>Heavy braking and braking with ABS:
The tail lamps also light up with the
same intensity as the standard brake
lamp units to enhance the warning
effect of the brake lamps.

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 the spare 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 can not only
compromise your vehicle's stability, but
also lead to tire damage and the risk of an
accident.
Do not drive with deflated, i.e. flat tires,
except run-flat tires. 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 vehi-
cle.<
Checking inflation pressure
Only check tire inflation pressure when
the tires are cold. i.e. after a maximum of
2 hours' driving or when the vehicle has
been parked for at least 2 hours. When tires
are warm, the tire inflation pressure
increases.
After correcting the inflation pressure(s),
always reinitialize the Flat Tire Monitor,
refer to page 95.
Inflation pressure for original tires
The inflation pressures for your standard
tires can be found on the door pillar when
you open the driver's door.
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.<

Temperature
The temperature grades are A Ð the
highest Ð, B, and C, representing the tire's
resistance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance
which all passenger car tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A repre-
sent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load-
ing, either separately or in combination,
can cause heat buildup and possible tire
failure.<
Run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire, refer to page 193.
M+S
Winter and all-season tires.
These have better winter properties than
summer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects
lodged in the tread. Check the tread depth.
Tire tread
The tread depth should not fall below e in/
3 mm.
At tread depths below e in/3 mm, there is
an increased risk of high-speed hydroplan-
ing, even when only small amounts of
water are present on the road surface.As winter tires display a noticeable loss in
their ability to cope with cold-weather driv-
ing conditions once the tread wears to
below k/K in/4 mm, to ensure continued
safety you should always have such tires
replaced.
Wear indicators at the tread-groove base,
refer to arrow, are distributed over the tire's
circumference and are marked on the side
of the tire with TWI Ð Tread Wear Indicator.
These indicators signal at a tread depth
of k/FK in/1.6 mm that the legally permitted
wear limit has been reached.
Tire damage
Unusual vibrations encountered dur-
ing normal vehicle operation can
indicate tire failure or some other vehicle
defect. This can, for example, be caused
by driving over curbs.
These kinds of problems may also be
signaled by other changes in vehicle
response, such as a strong tendency to
pull to the left or right. Should this occur,
respond by immediately reducing your
speed. Carefully proceed Ð or have your
vehicle towed Ð to the nearest BMW center
or tire dealer to have the wheels or tires
inspected.
Tire damage, extending to sudden and
complete loss of pressure in extreme
cases, can pose a potentially lethal safety
hazard for the vehicle's occupants and
other road users alike.<

Replacing wheels/tires
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled pro-
fessionals only. The technicians at your
BMW center will be glad to assist you with
the required professional knowledge and
specialized equipment.<
The correct wheel and tire combination
affects various systems whose function
would otherwise be impaired, e.g. ABS or
DSC.
Have the wheel and tire assemblies bal-
anced every time either a wheel or a tire is
replaced.
BMW does not recommend the use
of retreaded tires, as otherwise driv-
ing safety may be reduced. Possible varia-
tions in the design and the age Ð which
could be substantial Ð of the carcasses can
lead to unusually rapid wear.<
The right wheels and tires
BMW recommends that you use only
wheel and tire combinations that
BMW has tested and approved for your
particular vehicle. Variations in factors such
as manufacturing tolerances mean that
even wheels and tires with identical official
size ratings could actually have different
dimensions than the approved units Ð these
differences could lead to body contact, and
with it the risk of severe accidents. If non-
approved wheels and tires are used, BMW
cannot evaluate their suitability, and there-
fore cannot be held liable for driving
safety.<
To maintain good handling and vehicle
response, use only tires of a single tread
configuration from a single manufacturer.
After a flat tire, always remember to have
the original wheel and tire combination
remounted on the vehicle as soon as pos-
sible.
Recommended tire brands
BMW tests certain tire brands for each tire
size, classifies them as road-safe and
approves them. You can find out about
these at specialized dealers or at your
BMW center. Observe any country-specific
regulations, e.g. on making a correspond-
ing entry in the vehicle documents.
The factory-mounted tires have been spe-
cially selected to provide optimized perfor-
mance when installed on your vehicle; if
properly cared for, they will provide a com-
bination of safety and excellent ride com-
fort.
Run-flat tires
If your BMW is equipped with run-flat tires,
refer to Run-flat tires, only use these tires,
as in the event of a breakdown there is no
spare wheel available.
Special characteristics of winter
tires
BMW recommends winter tires for use in
cold winter driving conditions. Although
so-called all-season M+S tires provide bet-
ter winter traction than summer tires, they
generally fail to provide the same levels of
cold-weather performance as winter tires.
When switching to winter tires, observe the
description at Tire condition, and Replac-
ing wheels/tires, refer to page 191.
Run-flat tires
If your BMW is equipped with run-flat tires,
refer to Run-flat tires, only use these tires,
as in the event of a breakdown there is no
spare wheel available.
Observing speed ratings
Never exceed the maximum speed
for which the winter tires are rated.
Unprofessional attempts by laymen to ser-
vice tires can lead to damage and acci-
dents. Have this work performed by skilled
professionals only. The technicians at your
BMW center will be glad to assist you with
the required professional knowledge and
specialized equipment.<

Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as pos-
sible. Always protect tires against all con-
tact with oil, grease and fuels.
Do not exceed the maximum tire inflation
pressure indicated on the side wall of the
tire.
Run-flat tires*
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire. They consist of self-con-
tained tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of pres-
sure drop and driving remains possible to
a restricted degree.
If you switch from summer to winter
tires, or vice versa, use run-flat tires,
as in the event of a breakdown there is no
spare wheel available. In this case, BMW
recommends that you consult your BMW
center. Your BMW center is qualified to
handle run-flat tires and equipped with the
necessary special tools.<
Continuing driving with a damaged
tire
Driving on run-flat tires can continue,
depending on the vehicle load and the
severity of the tire damage, at a maximum
speed of 50 mph/80 km/h.
In the case of complete inflation pressure
loss, 0 psi/kPa, or obvious tire damage,
you can estimate the possible distance for continued driving on the basis of the fol-
lowing guide values:
>With low load:
1 to 2 persons without luggage:
Approx. 150 miles/250 km
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
Approx. 90 miles/150 km
>With full load:
More than 4 persons, luggage compart-
ment full:
Approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. With
inflation pressure loss, the driving charac-
teristics change, for example reduced track
stability on braking, extended braking dis-
tance, and altered self-steering character-
istics.<
Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves
them. Consult your BMW center for more
information. BMW recommends only using
these approved, narrow-link snow chains.
These snow chains are approved exclu-
sively for use in pairs on the rear wheels,
and should only be mounted on tires
with the dimensions 245/50 R 18. Observe
the manufacturer's instructions when
installing snow chains.Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains mounted.
After mounting snow chains, do not
activate the Flat Tire Monitor.
When you are driving with snow chains, it
can be beneficial to switch off DSC briefly,
refer to page 93.<

Replacing components
204 surface of the front tire on the side
opposite the side being raised. If the
vehicle is parked on a downward slope,
place the wheel chock securely in front
of the tire. If the wheel must be changed
on a surface with a more severe slope,
take additional precautions to secure
the vehicle from rolling
3.Loosen the lug bolts 1/2 a turn
4.Set up the jack beneath the jacking
point closest to the flat tire. Ensure that
the entire surface of the jack's base is in
firm contact with the ground and that
the jack itself is standing completely
vertical, not tilted, and that the fitting on
the top of the jack will align with the
rectangular recess on the vehicle when
you raise it, refer to illustration
5.Jack the vehicle up until the wheel you
are changing is raised from the ground
6.Unscrew the lug bolts and remove the
wheel
7.Remove accumulations of mud or dirt
from the mounting surfaces of the
wheel and hub. Clean the lug bolts
8.Position the spare wheel. Secure the
wheel by turning at least two lug bolts
into opposite bolt holes
9.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diag-
onal pattern
10.Lower the jack and remove it from
beneath the vehicle
11.Tighten the lug bolts in a diagonal pat-
tern
12.Check and correct the tire inflation
pressure at the earliest opportunity. Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
After mounting the spare wheel or correct-
ing the inflation pressure, reinitialize the
Flat Tire Monitor, refer to page 95.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.
To ensure safety, always have the lug bolts
checked with a calibrated torque wrench
as soon as possible to ensure that they are
tightened to the specified torque.
The tightening torque is 101 ft-lb/
140 Nm.<
Reverse the removal sequence to store the
wheel and tools in the vehicle.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
Always have damaged tires replaced and
the wheel and tire assembly rebalanced at
the earliest possible opportunity.
Driving with the spare tire
On certain wheel-tire combinations,
the size of the spare tire deviates from
that of the rest of the tires. The spare tire is
fully capable of running in all load and
speed ranges. However, to recreate the
original conditions, the tire should be
replaced as soon as possible.<

Run-flat tires*
You will recognize run-flat tires by a circu-
lar symbol containing the letters RSC on
the side of the tire. They consist of self-
contained tires and special rims. The tire
reinforcement ensures that the tire retains
some residual safety in the event of pres-
sure drop and driving remains possible
to a restricted degree. The vehicle is
equipped with a Flat Tire Monitor which
indicates punctures.
The reinforcement on the flanks of the
tires means that it is usually not pos-
sible to detect an air loss from outside.<
Flat tire
If you have a flat tire, the indicator lamp
symbol in the Check Control will light up in
red, and a message will appear. In addition,
a gong sounds.
You can find more detailed information on
the Flat Tire Monitor on page 95.
Reduce vehicle speed carefully to under
50 mph/80 km/h, avoiding hard brake
applications and steering maneuvers.
If the defective wheel is not recognizable
as such immediately, check the inflation
pressure in all four tires.
For reasons of safety, do not arrange
for run-flat tires to be repaired. Your
BMW center has the information needed
for working with these tires and is equipped
with the necessary special tools.<
Continuing driving with a damaged
tire
Driving on run-flat tires can continue
depending on the vehicle load and the
severity of the tire damage, at a maximum
speed of 50 mph/80 km/h. You can deter-
mine the possible mileage for continued
driving on the basis of the following general
indications:
>Tire inflation pressure 0 psi/kPa:
With empty vehicle approx. 90 miles/
150 km
With full payload approx. 30 miles/
50 km
>Tire inflation pressure 7 psi/50 kPa to
15 psi/100 kPa:
Approx. 300 miles/500 km
>Tire inflation pressure greater than
15 psi/100 kPa:
Approx. 600 miles/1,000 km.
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the case
of air loss, you can expect changes in vehi-
cle handling such as reduced lane stability,
longer braking distances, and changes in
self-steering properties.<
