Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
by
+ are tested for proper functioning whenever
the ignition key is turned. They each light up
once for different periods of time.
If a malfunction occurs in one of the monitored
systems, the corresponding light does not go
out after the engine has started, or it lights up
again while the vehicle is in motion. You can find
more information about each system on the
specified pages.

Safe seating position
For relaxed driving with as little fatigue as pos-
sible, you should select a seating position that
reflects your personal requirements. In combi-
nation with the safety belts and airbags, the cor-
rect seating position also plays an important
role in enhancing occupant safety in the event
of an accident. To ensure that the vehicle's
safety systems provide you with optimal pro-
tection, we request that you direct your careful
attention to the following section.
For supplementary information on transporting
children refer to page33.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
hold the steering wheel by its rim with hands at
the 9 and 3 o'clock positions to minimize the
r i s k o f i n j u r i e s t o y o u r h a n d s o r a r m s i n t h e e v e n t
of airbag deployment.
Never allow any objects, individuals or animals
to obstruct the areas between passengers and
airbags.
Never use the front airbag's cover as a storage
tray or support for objects of any kind. Ensure
that the passenger is correctly seated, i.e. does
not prop feet or legs against the dashboard.
Otherwise, leg injury could result if the knee air-
bag and front airbag suddenly deployed.
Never let an occupant's head rest near or on a
side airbag because the inflating airbag could
cause a serious or fatal injury.<
Even when all these guidelines are observed,
the risk of injury as a result of contact with the
airbags cannot entirely be ruled out in some sit-
uations. In sensitive individuals, the ignition and
inflation noise may induce a mild hearing loss
that is temporary in most cases.
For airbag locations and additional information
on airbags, refer to page53.
Safety belts
Always fasten your safety belt before starting
off. As supplemental restraint devices, the air-
bags are designed to enhance the effective-
ness of the safety belts, and not to replace
them.
Your vehicle offers two sitting positions, each of
which is equipped with a safety belt.
At all times, occupants should sit upright
and be properly restrained: infants and
small children in appropriate child-restraint sys-
tems; larger children and adults using the safety
belts.
Expectant mothers should always wear their
safety belts, taking care to position the belt in
the pelvic area against the lower hips, where it
will not exert pressure against the abdomen.
N e v e r a l l o w m o r e t h a n o n e p e r s o n t o w e a r a si n -
gle safety belt. Never allow infants or small chil-
dren 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; wear it as snugly against your
body as possible. Do not allow the belt to rest
against hard or fragile objects. Otherwise, the
belt in the pelvic area could slide over the hips in
the event of a frontal impact, leading to abdom-
inal injury. Avoid wearing bulky clothing and pull
the belt in the upper-body area upward periodi-
cally to retension it. Otherwise, the restraining
effect of the safety belt could be diminished.<
For information on using the safety belts, refer
to page30.

Adjustments

Seats
Before adjusting your seat, always
observe the following precautions
Never try to adjust your seat while operat-
ing the vehicle. The seat could respond
with an unexpected movement, and the ensu-
ing loss of vehicle control could result in an
accident.
Never ride with the backrest inclined to an
extreme angle – this also applies to the passen-
ger seat. If you do, there is a risk that you will
slide under the safety belt in the event of an
accident, thus reducing the protection provided
by the safety belt.<
In addition, observe the instructions regarding
damaged safety belts on page30.
Seat adjustment
1 Backward/forward
Pull lever1 and slide the seat into the desired
position.
After releasing the lever, move the seat back-
wards or forwards slightly to ensure that the
latch engages securely
2Height
Pull lever 2 and apply weight to or remove
weight from the seat as required
3Backrest
Pull lever3 and apply weight to or remove
weight from the backrest as required.
Head restraints
Head restraints reduce the risk of neck
injuries in the event of an accident. Adjust
the head restraint in such a way that its center is
at approximately ear level.<
Adjusting the height
>To move up: pull.
>To move down: press button1 and push
the head restraint downward.

Safety function
1.Close the driver's door and turn the ignition
key to position 0 or 2
2.Press and hold the desired memory button
1, 2 or 3 until the adjustment process is
completed.
If you press the M
EMORY button accidentally:
Press the button again; the indicator lamp goes
out.
Before activating the programmed
adjustment feature, ensure that the space
behind the driver's seat is empty and unob-
structed. If you fail to do so, objects behind the
seat could be damaged, should the seat move
backward.<
Seat heating*
The seat cushion and backrest can be heated
with the ignition key in position 2.
You can call up different heating modes by
repeatedly pressing the buttons.
The seat heating can also be switched off from
the higher heating modes:
Press the button and hold it slightly longer.
Safety belts
Comply with the instructions on page27,
or the occupants' personal safety will be
diminished.<
Make sure every occupant fastens his or her
safety belt. As supplemental restraint devices,
the airbags are designed to enhance the effec-
tiveness of the safety belts, and not to replace
them.
To fasten
Make sure you hear the lock engage in the belt
buckle.
To unlock
1.Press the red button in the belt buckle
2.Hold the belt
3.Guide the belt back into its reel.
The upper belt attachment point is suitable for
all body sizes, provided that the person is sitting
correctly, refer to page28.
Safety belt reminder
The indicator lamp flashes or lights up.
A signal also sounds. Check if the
safety belts have been properly fas-
tened.
The safety belt reminder is operational above a
speed of approx. 5 mph / 8 km/h. The reminder
can also occur if objects are on the passenger
seat.
Damaged safety belts
If the safety belts are damaged or
stretched in an accident: have the entire
belt system, including the tensioning mecha-
nisms, replaced at your BMW center. Have the
belt anchorage points inspected for damage at
the same time. Failure to observe this precau-
tion may prevent the safety belts from effec-
tively providing optimal protection when
needed.<

Transporting children safely
Children on the passenger's
seat
Deactivating/reactivating passenger
airbags
The passenger airbags must be deacti-
vated before using a rear-facing child-
restraint system on the passenger seat, refer
also to page34 for explanation.
BMW also recommends that the passenger air-
bags be deactivated if a child is transported in a
front-facing child-restraint system, regardless
of the age of the child. If you transport a child in
the passenger seat, not an infant in a rear-fac-
ing seat, who is properly seated and seat-belted
at all times, the potential benefits of airbags
deploying in an accident generally outweigh the
risks of the child being injured by the force of a
deploying airbag.
Therefore, you should deactivate the passen-
ger airbags only if you find it difficult to ensure
that the child will remain properly seated and
seat-belted at all times.
Always position the passenger seat as far back
as possible and at the lowest level.
The above warning and recommendations are
compatible with regulations established by the
National Highway Traffic Safety Administration,
NHTSA, permitting the deactivation of passen-
ger airbags by means of an on-off switch for
members of certain at-risk groups.
Specifically, the at-risk groups are:
>Infants in rear-facing infant seats
>Persons with certain medical conditions
>Children aged 12 and under in the passen-
ger seat.
NHTSA provides this information via their web-
site, www.nhtsa.dot.gov, or via their Auto
Safety Hotline toll-free at
1-800-424-9393 or 366-0123
in Washington, D.C. area.<
The concept
Passenger airbags can be deactivated/reacti-
vated with the vehicle ignition key. The key
switch is located on the outer passenger's side
of the instrument panel.
The passenger airbags can only be deactivated
or reactivated with the vehicle standing still,
ignition off and the passenger door open.
Deactivation
Deactivation of the passenger airbags system
deactivates the passenger front, knee and side
airbag. The airbags on the driver side remain
active.
Using the vehicle ignition key, turn the key
switch to the OFF position. Note, the passenger
airbags will remain deactivated with the switch
in this position.
As soon as the reason for the deactivation
of the passenger airbags no longer exists,
you must reactivate these airbags so that they
can deploy in an accident within their normal
deployment range.<
Reactivating
Using the vehicle ignition key, turn the key
switch to the ON position.
All airbags in the vehicle are activated and will
be triggered under appropriate conditions.

Passenger airbags lamp
The center console contains one of the indica-
tor lamps shown in the illustration.
The system checks that the airbag system is
functioning properly when the ignition key is
turned, and the indicator lamp in the central
console lights up for several seconds.
>The indicator lamp lights up continuously
when the passenger airbags are deacti-
vated
>If the passenger airbags are activated, it
goes out after several seconds
The passenger airbags are deactivated
when the key switch is in the ON position
and the passenger seat is unoccupied. The
indicator lamp is not lit.<
At all times, occupants should sit com-
fortably upright and be properly
restrained: infants and small children in appro-
priate child-restraint systems; larger children
and adults using the safety belts. Please note
that the word Airbag imprinted on the door trim
panel indicates the airbag's location.<
Seating position for children
This is the correct way a larger child no longer
using a child-restraint system should sit wear-ing the safety belt, when the airbag system is
activated.
Installing child-restraint
systems
Before installing any child-restraint system or
child seat, read the following:
Never install a rear-facing child-restraint
system in the passenger seat of this vehi-
cle, unless the passenger airbags have been
turned off and the indicator lamp in the center
console indicates that the passenger airbags
are deactivated. For a child, not an infant, cer-
tain precautions should be taken. Position the
passenger seat as far back as possible and at
the lowest level. This important precaution is
intended to maximize the distance between the
airbags and the child. Younger children should
be secured in an appropriate forward-facing
child-restraint system that has first been prop-
erly secured. Older children should be tightly
secured with a safety belt, sitting with their back
against the vehicle seat back. Always ensure
that all occupants, of all ages, remain properly
and securely restrained at all times.<
Always follow the manufacturer's instruc-
tions concerning installation and use;
otherwise the system's protective function
could be impaired. After an accident, have all
parts of the affected safety belt system
inspected and/or replaced by your BMW cen-
ter.<
Commercially-available child-restraint systems
are designed to be secured with a lap belt or
with the lap belt portion of a combination lap/
shoulder belt. Improperly or inadequately
installed restraint systems can increase the risk
of injury to children. Always read and follow the
instructions that come with the system.

Flat tire warning
The warning lamp in the instrument
cluster lights up in red. This visual alert
is accompanied by an acoustic warning
signal. There is a flat tire or a signficant loss of
tire pressure.
1.Carefully reduce your speed to under
50 mph / 80 km/h. Avoid strong braking and
steering maneuvers. Do not exceed a maxi-
mum speed of 50 mph / 80 km/h.
Do not continue driving if the vehicle
is not equipped with Run Flat tires,
refer to page82. If you continue to drive
with a flat tire, a serious accident could
result.<
2.Check the inflation pressure in all four tires
as soon as possible.
If the inflation pressure is correct in all
four tires, it is possible that the Flat
Tire Monitor was not initialized. In this case,
initialize the system.<
3.If there is a total loss of tire inflation pres-
sure, 0 psi/0 kilopascal, or obvious tire dam-
age, you can gauge the mileage for contin-
ued driving on the basis of the following
indications:
>With a light load:
1 person without luggage:
approx. 155 miles/250 km
>With a medium load:
1 person, luggage compartment full,
or
2 persons with luggage:
approx. 90 miles/150 km
>With a full load:
2 persons, luggage compartment full:
approx. 30 miles/50 km.
Drive cautiously. Do not exceed a speed
of 50 mph / 80 km/h. Driving characteris-
tics change if there is a loss of tire pressure.
This includes diminished track stability during
braking, longer braking distances and modified
steering. If unusual vibrations occur while driv-
ing, this can indicate a complete failure of the
damaged tire. Reduce your speed and pull over as soon as possible. Do not continue driving
and contact a BMW center.<
Malfunction
The indicator lamp in the instrument
cluster lights up yellow. The Flat Tire
Monitor is malfunctioning or out of
order. Have the system checked as soon as
possible.
Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and passenger
2Side airbags for driver and passenger
3Knee airbags for driver and passenger
Protective effect
Comply with the instructions on page27,
or the occupants' personal safety will be
diminished.<
The front airbags help protect the driver and
passenger in the event of a head-on collision
where the protection provided by the safety belt
alone would not be adequate. The side airbags
help provide protection in the event of a colli-
sion from the side. Each of the side airbags is
designed to help support the seat occupant's
upper body. The knee airbags help provide
additional protection in the event of a head-on
collision.
The airbags are deliberately not triggered in
every impact situation, e. g. not in less severe
accidents, certain roll-over conditions, or rear-
end collisions.

Technology for safety and driving convenience
54 For information on the correct seating position,
refer to page27.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way. Do not attempt to
remove the airbag retention system from the
vehicle. Never modify or tamper with either the
wiring or the individual components in the air-
bag system. This category includes the uphol-
stery in the center of the steering wheel, on the
instrument panel, and the side trim panels on
the doors. Do not attempt to remove or disman-
tle the steering wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns.
If you note any indication of system malfunc-
tion, if you desire to have an airbag deactivated,
or if the airbag retention system is triggered in
response to an accident, you should always
entrust all inspection, repair and dismantling
operations to your BMW center.
Unprofessional attempts to service the system
could lead to failure in an emergency or to
undesired airbag activation, either of which
could result in personal injury.
To ensure compliance with official safety regu-
lations, please also entrust disposal of airbag
generators to a BMW center.<
Airbag warning information is also provided on
the sun visors.
Automatic deactivation of the
passenger airbags
Before transporting a child on the pas-
senger seat be sure to observe the infor-
mation/instructions under Transporting chil-
dren safely, refer to page33.<
Your BMW has a seat occupation detection
system. By evaluating the weight on the pas-
senger's seat, the system detects whether or
not the seat is occupied by a child in the child-
restraint system or an adult.
>When a child is seated in the child-restraint
system or in an empty seat, the front, side
and knee airbags are automatically deacti-
vated on the passenger's side>When an adult is traveling in the passen-
ger's seat, the front, side and knee airbags
remain active on the passenger's side.
Although not desired, it can occur in the
case of heavier children that the passen-
ger airbags remain active or, in the case of very
light adults or young persons, that the passen-
ger airbags are deactivated. The condition of
the passenger airbag system will be shown by
the indicator lamp in the central console, refer
to Passenger airbag status lamp below. If the
indicator lamp indicates that the passenger air-
bags are active and you want them to be deac-
tivated, the airbags have to be deactivated with
the vehicle ignition key and the key switch on
the outer passenger's side of the instrument
panel. Apart from passengers, do not place any
additional objects on the passenger seat. Do
not fit seat covers, seat cushion padding, ball
mats or other items to the passenger seat
unless they are specifically recommended by
BMW. Do not place any items under the seat.
Otherwise, the function of the seat occupation
detection could be impaired.<
Operational readiness of the airbag
system
The airbag indicator lamp in the instrument
cluster indicates the operational readiness of
the entire airbag system and the safety belt ten-
sioners as of ignition key position 1.
The indicator lamp goes out after a few sec-
onds.
Airbag system malfunction
>The indicator lamp does not light up as of
ignition key position 1
>The warning lamp lights up continuously.

Tire coding
Understanding the lettering on the tire sidewall
makes it easier to identify and choose the cor-
rect tires.
Tire size
e.g. 225/50 R 16 92 V
Nominal width in mm
Cross-sectional
ratio in %
Radial belt construction
Rim diameter in inches
Load index,
not on ZR tires
Speed code letter,
in front of the R on ZR tires
Speed code letter
Q= up to 105 mph / 160 km/h
T= up to 118 mph / 190 km/h
H= up to 131 mph / 210 km/h
V= up to 150 mph / 240 km/h
W= up to 167 mph / 270 km/h
Y= up to 186 mph / 300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
DOT code:
e.g. DOT xxxx xxx 5004
Manufacturer's code
for tire brand
Tire size and
tire version
Tire age
Tire age
The date on which the tire was manufactured is
indicated by the code on the sidewall:
DOT … 5004 indicates that the tire was manu-
factured in week 50 of the year 2004.BMW recommends the replacement of all tires
every 6 years at the latest, even if a tire usage of
10 years is possible.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA
Temperature A
DOT quality grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one-half, 1 γ, times as well on the govern-
ment course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may
depart significantly from the norm due to varia-
tions in driving habits, service practices and dif-
ferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.<
