Starting the engine
Do not run the engine in closed rooms,
otherwise the inhaling 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, otherwise such a vehicle repre-
sents a potential safety hazard.
Before leaving the car with the engine running,
place the transmission in idle or move the
selector lever to position P and apply the hand-
brake to prevent the car from moving.<
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive immediately at a moder-
ate engine speed.
Do not depress either the brake or the
clutch until you are ready to start the
engine. The engine is started immediately
when you briefly touch the start/stop button
and depress the brake if the car has automatic
transmission, or the clutch if the car has manual
transmission.<
Manual transmission
1.Apply the handbrake.
2.Depress the clutch and shift to idle position.
3.Briefly press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Automatic transmission
1.Depress the brake.
2.Move the selector lever to position P.
3.Briefly press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Sequential manual gearbox SMG*
1.Depress the brake.
2.Engage selector lever position N and make
sure that this position is displayed in the
instrument cluster.
3.Start the engine.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
If the engine does not start, depress the
brake and push the selector lever to the
right, then engage position N. Observe the dis-
play in the instrument cluster while doing so.<
Special starting conditions
In the following situations, press the accelerator
pedal halfway down when starting the engine:
>If the engine does not start on the first
attempt, for instance when it is extremely
hot or cold.
>If the engine is started at very low tempera-
tures, below approx. + 57/–156, at high
altitudes above approx. 3,300 ft/1,000 m.
Avoid frequent starting in quick succes-
sion or repeated start attempts in which
the engine does not start. Otherwise, the fuel is
not burned or inadequately burned and there is
a danger of overheating and damaging the cat-
alytic converter.<
Switching off the engine
Always take the remote control with you
when you leave the vehicle.
When parking on a downhill incline, apply the

Automatic climate control
Comfortable interior climate
AUTO program7 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 temperature 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 also to Personal Profile
settings on page29.
Switching manual air distribution on/
off
The emerging air is directed to the
windows, to the upper body area or
to the footwell.
You can switch the automatic air
distribution back on by pressing the AUTO but-
ton.

Temperature
Set the desired temperatures indi-
vidually for the driver's and front
passenger'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.
When you switch between different tem-
perature settings in quick succession, the
automatic climate control does not have
enough time to achieve the set temperature.<
Maximum cooling
At outside temperatures above
327/06 and when the engine is
running, you obtain a maximum
cooling effect as soon as possible.
The automatic climate control switches to the
lowest temperature and operates in recircu-
lated-air mode. Air flows at maximum rate only
from the vents for the upper body area. You
should therefore open them for maximum cool-
ing.
AUTO program
The AUTO program adjusts the air
distribution to the windshield and

sation from the windshield and
front side windows.
Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature setting.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is automatically switched
on along with the AUTO program. The passen-
ger compartment can only be cooled while the
engine is running.

Microfilter/activated-charcoal filter
The microfilter traps dust and pollen in the
incoming air. The activated-charcoal filter pro-
vides additional protection by filtering gaseous
pollutants from the outside air. Your BMW Cen-
ter replaces this combined filter during routine
maintenance.
You can call up further information in the service
requirements display, refer to page74.
Parked car ventilation
Concept
The parked car ventilation/heating provides
ventilation to the passenger compartment and
lowers its temperature, if necessary. It is ready
for use at any outside temperature, as of radio
readiness.
The parked car ventilation/heating remains
switched on for 30 minutes. Two different
switch-on times can be preselected. The sys-
tem can also be switched on and off directly.
Due to its high power consumption, it should
not be switched on twice in a row without driv-
ing in between to allow the battery to recharge.
The air emerges from the air vents for the upper
body area in the instrument panel. The air vents
must therefore be open.
The parked car ventilation system is operated
via iDrive.
Switching on/off directly

nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Interior and exterior mirrors, automatic
dimming feature*
The automatic dimming feature of the interior
and exterior mirrors
* is controlled by two photo
cells in the interior rearview mirror. One photo
cell is in the mirror frame, see arrow; the other is
on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photo cells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.
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.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page195.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
Sequential manual gearbox SMG
On uphill slopes, drive off without delay.
Do not hold the vehicle in place by
depressing the accelerator pedal; apply the
handbrake instead. Otherwise, the transmis-
sion could overheat.<
Also use the drive-off assistant, refer to
page87.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent brake pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<

Things to remember when driving
118 You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page58.
Never drive with the clutch held down,
with the transmission in idle or with the
engine switched off; otherwise, engine braking
action will not be present or there will be no
power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise pedal function could be
impaired.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating 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 minimum
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.
When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Before driving into a car wash
For general information about taking care of
your BMW, refer to the Caring for your vehicle
brochure.
With convenient access and automatic
transmission
Insert the remote control into the ignition
switch.The engine can be switched off when the selec-
tor lever is in position N. Refer also to page36.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
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 kilograms or YYY
pounds.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
1,400 lbs. and there will be five 150 lbs.
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs.:
1,400 lbs. minus 750 lbs. = 650 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
