Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
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. Ot herwise, the drive-off
assistant will no longer hold the car in place
after approx. 2 seconds an d the car will start to
roll backwards. <
Flat Tire Monitor FTM
The concept
The system does not measure the actual infla-
tion pressure in the tires.
The system detects a pressure loss in a tire by
comparing the rotational speeds of the individ-
ual wheels while moving.
In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre-
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirement
The system must have be en initialized while the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured.
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reinitialize the system.
System limitations
Sudden serious tire damage caused by
external influences ca nnot be indicated in
advance.<
A natural, steady pressure loss in all four tires is
not detected. Therefore, check the tire inflation
pressure regularly.
In the following situations, the system could be
delayed or malfunction:
> System has not been initialized
> Driving on snowy or slippery road surface
> Performance-oriented style of driving: slip
in the drive wheels, hi gh lateral acceleration
> Snow chains are attached
Initialization
The initialization process adopts the set infla-
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains.
For operating principle refer to page 82.
1. Start the engine imme diately before pulling
away, but do not drive off yet.
2. Briefly press the button 1 in the turn signal/
high beam lever up or down repeatedly until
the corresponding symbol and "RESET"
appear.
3. Press button 2 to confirm your choice of the
Flat Tire Monitor.

Tire Pressure Monitor TPM
The concept
Check the inflation pressure
in the four installed
tires. The system notifies you if there is a signif-
icant loss of pressure in one or more tires.
Functional requirement
The system must have been reset while the
inflation pressure was co rrect; otherwise, reli-
able signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.
System limitations
Sudden serious tire damage caused by
external influences ca nnot be indicated in
advance.<
The system does not function correctly if it has
not been reset. For example, a flat tire may be
indicated even though the tire inflation pres-
sures are correct.
The system is inactive and cannot indicate a flat
tire:
> When a wheel without TPM electronics is
installed.
> Interference with TPM by other systems or
devices with the same transmission fre-
quency.
Resetting the system
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.
For operating principle refer to page 82.
1. Start the engine, but do not start driving.
2. Briefly press the button 1 in the turn signal/
high beam lever up or down repeatedly until the corresponding symbol and "RESET"
appear.
3. Press button 2 to confirm your choice of the
Tire Pressure Monitor. The following dis-
play appears:
4. Press button 2 for approx. 5 seconds, until
the small warning lamp lights up in yellow
and the following appears in the display:
5. Start driving.
After several minutes of driving time, the
adjusted inflation pressures will be adopted as
nominal values. The resetting process is com-
pleted automatically as you drive. The indicator
lamp goes out after the system reset is com-
pleted.

ControlsTechnology for driving comfort and safety
The trip can be interrupted at any time. When
driving resumes, resetting continues automati-
cally.
Message for low tire inflation pressure
The warning lamps light up in yellow
and red. In addition, a signal sounds.
> There is a flat tire or substantial loss of tire
pressure in the indicated wheel.
> The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressure s initialized last.
Reduce speed and stop the vehicle with cau-
tion. Avoid sudden braking and steering
maneuvers. If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious accidents. <
When a low tire pressure is reported, the
Dynamic Stability Control DSC is activated.
Actions in the event of a flat tire
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
When driving with a damaged tire:
1. Avoid sudden braking and steering maneu-
vers.
2. Do not exceed a speed of 50 mph/80 km/h.
3. At the next opportunity, check the inflation
pressure in all four tires.
If the inflation pressure is correct in all four
tires, then the Tire Pressure Monitor may
not have been reset. The system must then
be reset.
Possible driving distance with complete loss of
tire inflation pressure:
The distance it is possible to drive with a flat tire
depends on the load and the stress on the vehi-
cle while driving. With an average load, it may be possible to drive
for approx. 50 miles/80 km.
When driving with damaged tires, the handling
characteristics ch
ange, e.g. the vehicle will skid
sooner when braking, braking distances will be
longer, or self-steerin g response will change.
Adapt your driving style accordingly. Avoid
turning abruptly and driving over obstacles
such as curbs, potholes, etc.
Since the possible driving distance depends to
a considerable degree on the strain exerted on
the vehicle while driving, it can be shorter or,
with a gentle driving style, can also be longer,
depending on the speed, road condition, out-
side temperature, vehicle load, etc.
Drive cautiously an d do not exceed a
speed of 50 mph/80 km/h.
When there is a tire pressure loss, the handling
characteristics change , e.g. there will be
reduced directional stability during braking,
braking distances will be longer, and self-steer-
ing response will change. <
Vibrations or loud noises while driving can
indicate complete fa ilure of the tire.
Reduce your speed and bring the vehicle to a
stop; otherwise, tire components may become
detached, which could result in an accident. Do
not continue driving; instead, contact your
BMW center. <
Malfunction
The small warning lamp flashes in
yellow and then lights up continu-
ously; the large warning lamp lights
up in yellow. No punctures can be
detected.
Display in the follo wing situations:
> A wheel without TPM electronics has been
installed:
Have it checked by your BMW center.
> Malfunction
Have the system checked.
> Tire Pressure Monitor was unable to com-
plete the resetting process. Reset the sys-
tem again.

ss of airbag system
As of radio readiness, refer to page 57, the
warning lamp lights up br iefly to indicate that
the entire airbag system and the belt tensioners
are operational.
Airbag system malfunction
> Warning lamp does not light up at radio
readiness or beyond.
> Warning lamp remains permanently on.
In the event of a fault in the airbag system,
have it checked without delay; otherwise,
there is the risk that the system will not function
as intended even if a su fficiently severe acci-
dent occurs. <
Convertible: rollover
protection system
The rollover protection system is activated
automatically in the event of an accident, a crit-
ical driving situation, an extreme tilt in the car's
longitudinal axis or upon loss of ground contact.
The protection bars behind the rear head
restraints deploy within fractions of a second.
As a supplementary system to the reinforced
windshield frame, the rollover protection sys-
tem ensures that the necessary headroom is
maintained for all vehicle occupants. Always keep the area of movement of the
rollover protection system clear.
In minor accidents, yo u are protected by the
fastened safety belt and, depending on acci-
dent severity, by the sa fety belt tensioner and
multi-phase airbag retention system. <
Resetting
If the rollover protection system was not
impacted after being automatically activated, it
can be reset by lowering the protection bars to
their original positions. This does not require
tools.
1. Push the locking lever to one side and hold
it there.
2. Push the protection bar halfway down from
above.
3. Release the locking lever.
4. Push the protection bar down until it snaps
into place.
5. Repeat the procedure for the other protec-
tion bar.

Tire inflation pressures
Information for your safety
It is not merely the tire s' service life, but also
driving comfort and, to a great extent, driving
safety that depend on th e condition of the tires
and the maintenance of th e specified tire pres-
sure.
Check the tire inflation pressure regularly
and correct it, if nece ssary: at least twice a
month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive
with deflated, i.e. flat tires, except when using
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 vehicle. <
Checking pressure
Only check 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 tires are
warm, the tire inflation pressure is higher.
After correcting the ti re inflation pressure,
reset the Tire Pressure Monitor, refer to page
95, or reinitialize the Flat Tire Monitor,
refer to page 93.<
Inflation pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressure s apply to the tire
sizes approved and tire brands recom-
mended by BMW; a list of these is available
from your BMW center. <
For correct identification of the right tire infla-
tion pressures, observe the following:
> Tire sizes for 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 or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respecti ve tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100 mph or 160 km/h.
These tire inflation pressures can also be found
on the driver's side door pillar when the driver's
door is open.
The maximum permissible speed for
these tire pressures is 100 mph or
160 km/h. Do not exceed this speed; otherwise,
tire damage and accidents could occur. <
