The drive-off assistant enables you to drive off
smoothly on uphill gradients. The parking brake
is not required.
1. Hold the car in place by depressing the
brake.
2. Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Because the drive-off
assistant will not hold the car in place after
approx. 2 seconds, the car would otherwise
start to roll backwards. <

In the event of complete pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guidelines:
>With a light load:
1 person without luggage:
approx. 155 miles/250 km
> With a medium load:
1 person, cargo bay full, or 2 people
without luggage:
approx. 95 miles/150 km
> With a full load:
2 people, cargo bay full:
approx. 30 miles/50 km
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h. In the event of
pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibration or lo ud noises occur during
the journey, this may be an indication that the
damaged tire has finally failed. Reduce your
speed and pull over as soon as possible at a
suitable location. Otherw ise parts of the tire
could come loose, resulting in an accident. Do
not continue driving. Instead, contact your
BMW center. <
Message for unsuccessful system
reset
The warning lamp lights up yellow. A
message will appear on the Control
Display. The system is not reset after
a tire has been changed, for example.
Check the tire inflation pressure and reset the
system, refer to page 83.

Malfunction
The small warning lamp flashes in
yellow and then lights up continu-
ously; the larger warning lamp comes
on in yellow. On the Control Display,
the tires are shown in gray and a message
appears. No punctures can be detected.
This type of message is shown in the following
situations:
> If there is a malfunction
Have the system checked.

been mounted
> If TPM is temporarily malfunctioning due to
other systems or devices using the same
radio frequency.
Declaration according to
NHTSA/FMVSS 138
Tire Pressure Monitoring Systems
Each tire should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire infl ation pressure label. If
your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, yo u should determine the
proper tire inflation pressure for those tires. As
an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys-
tem, TPMS, that illuminates a low tire pressure
telltale when one or more of your tires are signif-
icantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underi nflated tire causes the
tire to overheat and ca n lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the dr iver’s responsibility to
maintain correct tire pressure, even if underin-
flation has not reached the level at which the
TPMS low tire pressure telltale illuminates.

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 upholstered covers
of the steering wheel, the dashboard and the
seats. Do not attempt to remove or dismantle
the steering wheel.
Do not touch the individual components imme-
diately 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, remo val and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to repair
procedures of BMW with correspondingly
trained personnel and th at has the required
explosives licenses. Unprofessional attempts to
work on the system could lead to failure in an
emergency or to undesi red airbag activation,
either of which could resu lt in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the
passenger airbags
The system determines whether the passenger
seat is occupied by meas uring the resistance of
the human body. Front, knee and side airbags
on the passenger side ar e activated or deacti-
vated accordingly.
Make sure that the passenger keeps his
or her feet in the footwell; otherwise, the
passenger airbags may not function properly. <
The indicator lamp above the interior rearview
mirror shows the current status of the passen-
ger airbags, deactivated or activated, refer to
Status of passenger airbags below.
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling instructions under Trans-
porting children safely, see page 48.
Malfunction of the automatic
deactivation system
The front, knee and side airbags can also be
deactivated by adolescents and adults sitting in
certain positions; the in dicator lamp for the pas-
senger airbags comes on. In such cases, the
passenger should change his or her sitting
position so that the pa ssenger airbags are acti-
vated and the indicator la mp goes out. If the
desired airbag status cannot be achieved by
changing the sitting posi tion, do not transport
the passenger in the vehicle.
To make sure that occupa tion of the seat cush-
ion can be detected correctly:
> Do not attach seat covers, seat cushion
padding, ball mats or other items to the pas-
senger 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. <
Status of passenger airbags
The indicator lamp for the passenger airbags
shows the functional status of the passenger's
front, knee and side airbags in accordance with
whether and how the passenger seat is occu-
pied. The indicator lamp shows whether the
passenger airbags are activated or deactivated.
> The indicator lamp lights up when a child
who is properly seated in a child-restraint
system intended for that purpose is
detected on the seat or the seat is empty.
The front, knee and side airbags for the pas-
senger are not activated.
Most child seats are detected by the sys-
tem, especially child seats required by the
NHTSA at the time of vehicle production.

Comfortable interior climate
AUTO program 7 offers the ideal air distribution
and air flow rate for almost all conditions, refer
to AUTO program below. All you need to do is
select an interior temp erature which is comfort-
able for you.
The following sections inform you in detail
about how to adjust the settings.
Most settings are stored for the remote control
currently in use, refer al so to Personal Profile
settings on page 28.
Air distribution, manual
Depending on the selected setting, the air is
directed to the windshie ld, to the upper body
area, to the knee area and into the footwell.
Adjusting air distribution manually
Press the button repeatedly until
the air distribution is set as
required. The corresponding LED lights up.
The manual air distribution is also switched on
when the AUTO program is deactivated.
Temperature
Set the desired temperatures indi-
vidually for the driver's and pas-
senger's sides.
The automatic climate control
achieves this temperature as quickly as possi-
ble regardless of the season, using maximum
cooling or heating power if necessary, and then
maintains it.
To give the automatic climate control
enough time to achieve the set tempera-
ture, do not switch be tween different tempera-
ture settings in quick succession. <
You can achieve maximum heating power with
the highest setting, rega rdless of the outside
temperature.
The lowest setting effe cts continuous cooling.

Drive defensively
Avoid unnecessary acceleration and braking
maneuvers. To do so, keep an adequate dis-
tance to the forward vehicle. A defensive
and smooth driving style keeps fuel con-
sumption down.
Avoid high engine speeds
Only use first gear when setting off. In second
and higher gears, accele rate without hesitation
or pauses. When accelerating, shift up before
reaching high engine speeds.
When you reach the desired speed, shift into
the highest applicable ge ar and drive with the
engine speed as low as possible and at a con-
stant speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Coasting
When approaching a red lig ht, take your foot off
the accelerator and coast to a stop in the high-
est applicable gear.
On a downhill slope, take your foot off the accel-
erator and coast in a suitable gear.
The fuel supply is interrupted when coasting.
Switch off the engi ne during lengthy
stops
Switch off the engine when stopping for lengthy
periods, e.g. at traffic lights, railroad crossings
or in traffic congestion. You achieve fuel sav-
ings even if standing time is as short as approx.
4 seconds.
Switch off functions you do not need at
the moment
Functions such as the air conditioner and the
seat or rear window heating draw large amounts
of power and consume a dditional fuel. Espe-
cially in city traffic and in stop and go driving
they have a considerable impact. Therefore,
switch these functions off when they are not
really needed.
Have the vehicle serviced
Have the vehicle serviced regularly to achieve
good economy and a long vehicle life. BMW
recommends having the vehicle serviced at a
BMW center. Also note the BMW service sys-
tem, refer to page 202.
General driving notes
Close the luggag e compartment lid
Operate the vehicle only when the lug-
gage compartment lid is closed. Other-
wise, exhaust fumes could enter the interior of
the vehicle. <
If the vehicle must be driven with the luggage
compartment lid open:
1. Close all windows.
2. Greatly increase the ai r volume of the auto-
matic climate control system, refer to
page 96.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to various sect ions of the exhaust sys-
tem, and never apply un dercoating to them.
When driving, standing at idle and while park-
ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, with the
risk of serious personal injuries and property
damage. Do not touch ho t exhaust tail pipes.
Otherwise there is a risk of burns. <
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brake be properly applied.<

Exhaust emission values
The warning lamp lights up:
The vehicle emissions are raised. The
trip can be continued. Have the car
checked as soon as possible.
Canadian models display this
warning lamp.
The lamp flashes under certain condi-
tions. This indicates excessive misfiring in the
engine. If this happens, you should reduce your
speed and visit your nearest BMW center as
soon as possible. Severe engine misfiring can
quickly lead to serious damage of emissions-
related components, espe cially the catalytic
converter.
The warning lamp comes on if the gas
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. If the gas ca p is then tightened, the
warning lamp should go out within a few days.
Data recorders
Your vehicle may be equipped with one or sev-
eral measuring or diagnostic modules or a
device for recording or sending certain vehicle
data or information. In addition, if you have

BMW Assist, refer to page 180.
> Radio readiness is on.
> The BMW Assist system is logged on to a
wireless network.
> The Emergency Request system is
operable.
> Equipment version with full preparation
package mobile phone. This equipment
makes it possible to send an Emergency
Request even if no mobile phone is paired
with the vehicle.
Once your service contract for BMW Assist
expires, the BMW Assist system can be deacti-
vated by a BMW center without you having to
visit a workshop. Once the BMW Assist system
has been deactivated, Emergency Requests
are not possible. The BMW Assist system can
be reactivated by a BMW center after a new
contract has been signed.
Sending an Emergency Request
1. Briefly press the cover flap to open.
2. Press the SOS button until the LED in the

received your Emergency Request, the BMW Assist Response Center contacts you
and takes further steps to help you. Even if you
are unable to respond, the BMW Assist
Response Center will be ab
le to initiate further
steps to assist you under certain conditions.
If the circumstances allo w this, remain in the
vehicle until the connection has been estab-
lished. You will then be able to provide a
detailed description of the situation.
In a BMW Assist Emerge ncy Request, data for
determining the necessary rescue measures
are transmitted to the BMW Assist Response
Center, e.g. the current po sition of your vehicle,
if it can be determined.
If the LED is flashing but the BMW Assist
Response Center cannot be heard over the
hands-free system, it is possible that the
hands-free system is malfunctioning. You may
still be heard by the BMW Assist Response
Center, however.
Under certain conditions, an Emergency
Request is sent automati cally immediately after
a severe accident. Th is Automatic Collision
Notification is not affected by the button being
pressed.
