volume.<
Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before reheating it 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.
The cooling effect can be intensified by activat-
ing recirculated air mode.
Depending on the weathe r, the windshield may
fog over briefly when the engine is started.
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.
Temperature
To increase the temperature, turn
the rotary switch clockwise
towards red.
For a lower temperature, turn the
rotary switch counterc lockwise towards blue.

4. Switch on cooling function 4.
5. Temperature 5 to the right, red.
6. Switch on rear window defroster 6 to
defrost the rear window .
Ventilation
1 Use the thumbwheels to smoothly open
and close the air vents
2 Use the levers to change the direction of the
airflow
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air in your direction, e.g. if it has become too hot
in the car.
Draft-free ventilation
Adjust the vents to let the air flow past you.
Microfilter
The microfilter removes dust and pollen from
the incoming air. Your BMW center replaces the
microfilter during routine maintenance.

Comfortable interior climate
AUTO program 5 offers the ideal air distribution
and air volume 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 page 25.
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.
The automatic air distribu tion can be switched
back on by pressing the AUTO button. The
cooling function is swit ched on automatically and the manual air distribution setting is
cleared.
Temperature
Turn to set the desired tempera-
ture.
The automatic climate control
achieves this temperature as
quickly as possible rega rdless of the season,
using maximum cooling or heating power if nec-
essary, and then maintains it.
Avoid rapid switching between different tem-
perature settings. The automatic climate con-
trol will not have sufficien t time to adjust the set
temperature.
Maximum heating power can be obtained with
the highest setting, regardless of the outside
temperature.
The system cools steadily in the lowest setting,
regardless of the outside temperature.

Things to remember when driving
Driving tips
Check tire inflation pressure regularly
Check the tire inflation pr
essure at least twice a
month and before embarking on a long journey,
and correct it if necessary.
Low tire inflation pressure causes higher rolling
resistance and thus increases fuel consumption
and tire wear.
Set off immediately
Do not let the engine wa rm up while the car is
still standing, but set off immediately at moder-
ate engine speed. This is the fastest way for the
cold engine to reach its operating temperature.
Drive defensively
Avoid unnecessary acceleration and braking
maneuvers. To do so, keep an adequate dis-
tance between you and th e vehicle in front of
you. 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, accele rate without hesitation
or pauses. When accelera ting, shift up before
reaching high engine speeds.
When you reach the desi red 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 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.
4seconds.
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
your BMW center. Also note the BMW service
system, refer to page 202.
General driving notes
Close the trunk lid
Only drive with the trunk closed. Failure to
do so may endanger passengers or other
road users or may damage the vehicle in the
event of an accident or a braking and evasive
maneuver. In addition, exhaust gas may flow
into the passenger compartment. <
If special circumstances make it absolutely nec-
essary to drive with the trunk open:
1. Close all windows and the glass roof.
2. Greatly increase the air volume of the air
conditioner or automatic climate control
system, refer to page 110 or113.
3. Drive cautiously.

Things to remember when driving
Driving tips
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 br aking is required. Even
light but consistent brak e 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 he lps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page 61.
Sport automatic transm ission with double
clutch: never drive with the transmission
in neutral or with the en gine switched off; other-
wise, there will be no en gine braking action and
no power assistance to the brakes and steering.
Manual transmission: never drive with the
clutch held down, with the transmission in neu-
tral or with the engine switched off; otherwise,
there will be no engine braking action and no
power assistance to the brakes and 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 driv en only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are le ss frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminan ts 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 wh ile the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their
approved carrying ca pacity, never over-
load the vehicle. Overlo ading can lead to over-
heating and increases the rate at which damage
develops inside the tires. In some situations,
this can result in sudden loss of tire pressure. <
Make sure that no liquids are spilled or
leak from their containers in the cargo
area, 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, damage to
the vehicle and unstable driving conditions
may result. <
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.
