Starting the engine
Do not run the engine in closed rooms,
otherwise the inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, otherwis e such a vehicle repre-
sents a potential safety hazard.
Before leaving the car wi th the engine running,
place the transmission in neutral or move the
selector lever to position P and set the parking
brake to prevent the car from moving. <
Avoid frequent starting in quick succes-
sion as well as repeat ed start attempts in
which the engine does no t start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter. <
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.

Parking brake
The concept
Your BMW is equipped with an electromechan-
ical parking brake that can be set and released
by using a button.
The parking brake is primarily used to prevent
the vehicle from rolling when it is parked.
When the vehicle is stationary, the parking
brake acts on the rear wheels via an electrome-
chanical mechanism. When the vehicle is rolling
or being driven, the parking brake acts on the disc brakes of the front and rear wheels via the
hydraulic brake system.
Setting the brake
Pull the button. The parking brake is set.
The indicator lamp in the instrument
cluster and the LED on the button light
up red. The parking brake is set.
Indicator lamp in Canadian models.
To set the parking brake, the remote control
does not need to be in the ignition lock.
While driving
In the rare case that the parking brake needs to
be used while driving, pull the button for a
lengthy period:
The vehicle brakes hard while the button is
being pulled. The indicator lamp in the instrument
cluster lights up red, a sound is issued
and the brake lamps light up.
Indicator lamp in Canadian models.
As soon as you brake the vehicle almost to a
standstill, approx. 2 mph/3 km/h, the parking
brake remains set.
Releasing
Take the remote cont rol with you when
leaving the vehicle so that children, for
example, cannot release the parking brake. <

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.
Status display
iDrive, for operating pr inciple refer to page16.
1. Press the button
The start menu is opened.
2. "Vehicle Info"
3. "Vehicle status"
4. "TPM"
5. The status is displayed.
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.
> If a wheel without TPM electronics has
been mounted
> If TPM is temporarily malfunctioning due to
other systems or devices using the same
radio frequency.

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.

Climate
96
Switching the cooling function
on and off
The cooling function cools and
dehumidifies the incoming air
before reheating it as required,
according to the temperature set-
ting. This function is only available while the
engine is running.
The cooling function he lps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weathe r, the windshield may
fog over briefly when the engine is started.
The cooling function is automatically switched
on along with the AUTO program.
Maximum cooling
Maximum cooling is achieved most
quickly at outside temperatures
above 32 7/06 and when the
engine is running.
The automatic climate control goes into recir-
culated-air mode at the lowest temperature. Air
flows at maximum rate from the vents for the
upper body area. You should therefore open the
vents for maximum cooling.
AUTO program
The AUTO program auto matically adjusts the
air distribution to the windshield and side win-
dows, towards the upper bo dy area, and into the
footwell and knee area.
The air flow rate and air distribution, in addition
to your temperature specifications, will be
adapted to outside influenc es as a result of sea-
sonal changes, e.g. sunlight or window conden-
sation.
The cooling is switched on automatically with
the AUTO program.
Switching on/off
Press the button.
Manual air distribution and air flow rate are acti-
vated when the AUTO program is deactivated.
AUTO program climate level
The climate levels can be used to vary the inten-
sity when the AUTO program is switched on.
For example, air flow is adjusted automatically
to optimize climate control.
When the AUTO program is
switched on, you ca n select the cli-
mate level of the AUTO program
using the buttons for controlling the manual air
flow rate.
The selected climate le vel is displayed by
an LED.
Convertible program
When the hardtop is open, the convertible pro-
gram is activated as well. In the convertible pro-
gram, the automatic climate control is opti-
mized for driving with the hardtop open. In
addition, the air flow rate is increased as vehicle
speed increases.
The effectiveness of the convertible pro-
gram can be enhanced considerably by
installing the wind deflector. <
Adjusting air flow rate manually
Press the left side of the button to
reduce air flow. Press the right side
of the button to increase it.
The air flow rate may be reduced to save battery
power. The display remains the same.
Switching the system on/off
With the blower at its lowest setting, press the
left side of the button to switch off the auto-
matic climate control. All displays are cleared
except for the rear window defroster if it is
switched on.
Press any button except the rear window
defroster to reactivate the automatic climate
control.
