Comfortable interior climate
The AUTO program4 offers the ideal air distri-
bution and air flow rate for almost all conditions.
All you need to do is select an interior tempera-
ture which is comfortable 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 page18.
Adjusting air distribution manually
The air distribution can be
switched on and off manually. The
air is directed to the windshield, to
the upper body area and to the
footwell. Automatic air distribution adjustment
is deactivated.
You can switch the automatic air distribution
back on by pressing the AUTO button. This
automatically switches on the cooling function
as well.
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.<
You can achieve maximum heating power with
the highest setting, regardless of the outside
temperature.
The lowest setting effects continuous cooling.
Maximum cooling
At outside temperatures above
327/06 and when the engine is
running, you obtain a maximum
cooling effect as soon as possible.

Climate
84 The function can be switched on when the fol-
lowing conditions are met:
>Up to 15 minutes after the engine has been
switched off
>While the engine is at operating tempera-
ture
>As long as battery voltage is sufficient
>At an outside temperature below 777/
256
The LED is lit when the function is on.
As of radio readiness, you can set the interior
temperature, air flow rate and air distribution.
Windows, defrosting and removing
condensation
Quickly removes ice and conden-
sation from the windshield and
front side windows.
Switch on the cooling function as well.
Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before reheating it as required,
according to the temperature setting. This
function is only available while the engine is
running.
The cooling function helps prevent condensa-
tion on the windows or removes it quickly.
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.
Rear window defroster
The defroster is switched off auto-
matically after a certain time.
Depending on your vehicle's
equipment, the upper wires serve
as an antenna and are not part of the rear win-
dow defroster.
Ventilation
1Use the knurled wheels to smoothly open
and close the air vents
2Use the lever to change the direction of the
airflow
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air in your direction, for instance if it has become
too hot in the car.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and not straight at you.
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.

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 consumption
down.
Avoid high engine speeds
Only use first gear when setting off. In second
and higher gears, accelerate without hesitation
or pauses. When accelerating, shift up before
reaching high engine speeds.
When you reach the desired speed, shift into
the highest applicable gear 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 light, 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 engine during lengthy
stops
Switch off the engine when stopping for lengthy
periods, e.g. at traffic lights, railroad crossings
or in traffic congestions. 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, seat
heating or rear window defroster draw large
amounts of power and consume additional fuel.
Especially in city traffic and in stop-and-go driv-
ing 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 page118.
General driving notes
Close the luggage 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 and the glass roof.
2.Greatly increase the air volume of the heat-
ing or automatic climate control system,
refer to page80 or83.
3.Greatly increase the air volume of the auto-
matic climate control system, refer to
page83.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed in
its vicinity, and never apply undercoating to
them. When driving, standing at idle and while
parking, 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 hot 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

Things to remember when driving
98 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 page111.
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 parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise greater clutch
wear will result.<
For more information about the drive-off assis-
tant, refer to page66.
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.<
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 page50.
Never drive with the clutch held down,
with the transmission in neutral 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
General information on caring for your BMW
can be found on page120.

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 page27.
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. This can ultimately
result in a sudden blow-out.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
bay, as this could result in damage to the vehi-
cle.<
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-lb. pas-
sengers in your vehicle, the amount of avail-
able 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
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of the occupants, the less cargo/lug-
gage can be transported.
