Malfunction
The warning lamp lights up yellow. The
Flat Tire Monitor is malfunctioning or
out of order. Have the system checked
as soon as possible.
TPM Tire Pressure Monitor*
The concept
TPM controls the tire inflation pressure in the
four mounted wheels. The system notifies you
if the tire inflation pressure has fallen signifi-
cantly in one or more tires.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be reset at the correct tire inflation
pressure.
Always use wheels equipped with TPM elec-
tronics, including a metal valve; otherwise, there
is no guarantee that the system will function
properly.
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot warn you of sudden, serious
tire damage due to external factors.<
The system does not function properly if it has
not been reset, e.g. it may identify a tire as flat in
spite of the fact that the tire is filled to the cor-
rect inflation pressure.
The system is deactivated and is unable to
detect flat tires if a wheel not equipped with
TPM electronics has been mounted, e.g. a
compact wheel, or if TPM is experiencing tem-
porary interference from other systems or
devices that use the same frequency.
Resetting system
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.<1.Start engine, but do not begin to drive.
2.Press the button until the yellow warning
lamp in the instrument cluster lights up for a
few seconds.
3.Begin driving.
After a few minutes of driving, the tire infla-
tion pressures in the tires are adopted as
the desired values to be monitored. The
resetting is completed during driving and
can be interrupted at any time without
requiring any input from you. The resetting
automatically continues when driving
resumes.
Low tire pressure message
The warning lamp lights up yellow. In
addition, a signal sounds. You have a
flat tire or a significant loss of tire pres-
sure in one or more tires.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify the damaged wheel or wheels.
If identification is not possible, con-
tact your BMW Sports Activity Vehi-
cle Center.<
3.Replace the damaged wheel, refer to
Wheel changes on page115.
4.Check tire inflation pressure and correct as
needed.
The compact wheel is not equipped with the
required TPM electronics and is not monitored
when mounted.
When driving with the compact wheel, the sys-
tem indicates a malfunction.

Technology for comfort, convenience and safety
56 Have the damaged tire replaced by your BMW
Sports Activity Vehicle Center or a workshop
that is familiar with TPM and works in accor-
dance with BMW repair procedures, using
appropriately trained personnel.
Malfunction
The yellow warning lamp flashes and
then lights up continuously. Flat tires
cannot be detected.
Such a message is displayed in the following
situations:
>When a malfunction is occurring:
Have the system checked
>When a wheel without TPM electronics is
mounted, e.g. a compact wheel
>When TPM is experiencing temporary inter-
ference from other systems or devices that
use the same frequency
NHTSA/FMVSS-required explanation
of 138 Tire Pressure Monitoring
System
Each tire, including the spare, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
then you should determine the proper tire infla-
tion pressure for those tires. As an added safety
feature, your vehicle has been equipped with a
tire pressure monitoring system, TPMS, that
illuminates a low tire pressure warning lamp
when one or more of your tires are significantly
underinflated. When the low tire pressure warn-
ing lamp lights up, you should stop and check
your tires as soon as possible, and inflate them
to the proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat
and can lead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping
ability. Please note that the TPMS is not a sub-
stitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire pressure, even if underinflation has not reached
the level to trigger illumination of the TPMS low
tire pressure warning lamp.
The TPMS malfunction indicator is combined
with the low tire pressure warning lamp. When
the system detects a malfunction, the warning
lamp will flash for approximately one minute and
then remain continuously illuminated. This
sequence will continue upon subsequent vehi-
cle startups as long as the malfunction exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons, includ-
ing the installation of replacement or alternate
tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check
the TPMS malfunction warning lamp after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.Brake force display
The brake lamps light up in two stages,
depending on how heavily you apply the brakes.
>Normal braking
The brake lamps and the center brake lamp
light up.
>Heavy braking
The rear fog lamps light up as well.

Airbags
The following airbags are located beneath the
marked covers:
1Front airbags
2Head airbags
3Side airbags in front and rear
*
Protective action
To ensure that the safety systems con-
tinue to provide optimum protection,
please follow the instructions on page27.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag cushions the side upper body area. The
respective head airbag cushions the head.
The airbags are intentionally not triggered in
every collision situation, e.g. they are not trig-
gered not in less serious accidents, or rear-end
collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Keep the instrument cluster and the windshield
in the region of the passenger free of foreign
objects, i.e. do not cover them with adhesive foil
or coatings, and do not use these areas to
mount brackets, e.g. for a navigation device or
mobile phone.
Do not attempt to remove the airbag retention
system from the vehicle. Do not modify the indi-
vidual components of the system or its wiring in
any way. This includes the padded covers in the center of the steering wheel, on the instrument
cluster, the doors, and the roof pillars as well as
the sides of the headliner. Do not attempt to
remove or dismantle the steering wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns.
In the event of malfunctions, deactivation, or
triggering of the airbag restraint system, have
the testing, repair, removal, and disposal of air-
bag generators executed only by a BMW Sports
Activity Vehicle Center or a workshop that
works according to BMW repair procedures
with correspondingly trained personnel and
that has the required explosives licenses. Oth-
erwise, unprofessional attempts to service the
system could lead to failure in an emergency or
undesired airbag activation, either of which
could result in personal injury.<
Airbag warnings and information are also pro-
vided on the sun visors.
Automatic deactivation of front
passenger airbags
By evaluating the pressure on the seat cushion
of the front passenger seat, the system detects
whether or not the seat is occupied. Depending
on the detection result, the system correspond-
ingly activates or deactivates the front and side
airbags for the passenger.
The indicator lamp located above the
inside rearview mirror indicates whether
the front passenger airbag system is currently
deactivated or activated, refer to Status of pas-
senger airbags in the section below.<
Before transporting a child in the front
passenger seat, read the safety notices
and follow the safety instructions under Trans-
porting children safely on page35.
When teenagers or adults assume certain sit-
ting positions, the front and side airbags on the
passenger side can deactivate; this causes the
indicator lamp for the front passenger airbag to
light up. If this happens, have them change their
sitting position so that the passenger airbag is
activated and the indicator lamp goes out. If the
desired status cannot be achieved by changing
their sitting position, then have the person ride

58 in the back. Do not attach seat covers, seat
cushion padding, ball mats or other items to the
passenger seat unless they are specifically rec-
ommended by BMW. Do not place any items
under the seat which could press against the
seat from below. Otherwise, a correct analysis
of the seat cushion is not ensured.<
Status of passenger airbags
The indicator lamp for the passenger airbag
indicates the functional status of the front and
side airbag on the passenger side depending on
whether or not the seat is occupied. By lighting
up, the indicator lamp indicates that the pas-
senger airbags deactivated.
>The indicator lamp lights up when a child
sitting as directed in a child restraint device
designed for this is detected.
The front and side airbags on the passenger
side are deactivated.
Most child seats are detected by the
system. It is particularly advisable to
use the child seats approved by NHTSA at
the time the vehicle was produced. After
installing a child's seat, make sure that the
indicator lamp for the front passenger air-
bags has illuminated. This indicates that the
system has detected the child's seat and
that the front passenger airbags have been
deactivated.<
>The indicator lamp does not come on as
long as a person of sufficient size and in a
correct sitting position is detected on the
seat. The front and side airbags for the pas-
senger are activated.
>The indicator lamp does not light up when
the seat is empty.In this case, the front and side airbags for
the passenger are deactivated.
Operational readiness of airbag system
When the ignition key is moved into position 1,
the warning lamp lights up briefly, thus indicat-
ing the operational readiness of the entire air-
bag system and the safety belt tensioners.
Airbag system malfunction
>Warning lamp does not come on when the
ignition key is moved into position 1.
>The warning lamp lights up continuously.
Have the airbag system checked immedi-
ately if a malfunction occurs; otherwise,
there is a danger of the system failing to
respond in the expected manner to an impact
occurring within its normal response range.<

Before folding down the rear backrests,
remove the cover caps for the LATCH
child-restraint system. Otherwise, impressions
can be left in the seat cushion.<
When you fold the backrest upright again,
be sure that the catch engages securely.
This causes the red warning field in the recess
to disappear. Otherwise, cargo can be thrown
into the passenger compartment during brak-
ing or evasive maneuvers, thus endangering the
passengers.<
To ensure that the safety belts continue
to provide optimum protection, please
follow the instructions on page27.<
Ski bag*
To create a flat cargo surface, you can remove
the ski bag and replace it with a tray before fold-
ing the rear backrest forward. The tray is
inserted in the same way as inserting the ski
bag, refer to Inserting ski bag on page76.
Cargo area cover
Pull the cargo area cover out by the handle and
hook it into the rear holders.You can carry light objects such as articles of
clothing on the cargo area cover.
Never place heavy, hard objects on the
cover. If you do so, they could endanger
passengers during braking or evasive maneu-
vers.
Do not allow the cover to snap back into place;
this can damage it.<

Hills
To prevent overheating and reduced effi-
ciency of the brake system, drive long or
steep downhill grades in the gear in which the
least braking is required. Otherwise, even light
but continuous pressure on the brake can lead
to high temperatures, brake wear and possibly
even brake failure.<
The braking action of the engine can be further
intensified by downshifting, all the way down to
first gear if need be. This strategy helps you
avoid placing excessive loads on the brake sys-
tem. Downshifting in manual mode of automatic
transmission, refer to page41. When descend-
ing hills slowly, use HDC Hill Descent Control,
refer to page52.
Never drive with the clutch depressed,
with the transmission in neutral, or with
the engine switched off; otherwise, you will
have neither the braking action of the engine or
nor its power assistance to the brakes or steer-
ing.
Never allow floor mats, carpeting, or other arti-
cles to protrude into the area around the brake
or accelerator pedals and obstruct their move-
ment.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended parking periods, and in operat-
ing conditions where brake applications are less
frequent, there is an increased tendency for
corrosion to form on rotors, while contaminants
accumulate on the brake pads. This occurs
because the minimal pressure which must be
exerted by the pads during brake applications
to clean the rotors is not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
Brake pads
The warning lamp lights up.
The brake pads have reached their min-
imum pad thickness. Have brake pads
replaced immediately.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating of the tire and increases the rate at
which damage develops inside the tires. The
ultimate result can assum e t h e f o r m o f a s u d d e n
blowout.<
Make sure that no fluids leak in the cargo
area; as otherwise the vehicle could be
damaged.<
Determining load limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, the vehicle
may be damaged and unstable driving con-
ditions 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 lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
990 lbs. and there will be five 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
240 lbs.:
990 lbs. minus 750 lbs. = 240 lbs.
5.Determine the combined weight of luggage
and cargo being loaded into and/or onto the
vehicle. This combined weight may not
