Switching cooling function on and off
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature setting.
This function is only available when the engine
is running.
The cooling function helps to avoid condensa-
tion on the window surfaces or to quickly
remove them.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is switched on automati-
cally with the AUTO program.
Maximum cooling
Maximally cooled air is obtained as
quickly as possible at an outside
temperature above approx. 327/
06 and with the engine running.
The automatic climate control switches into the
recirculated-air mode at the lowest tempera-
ture. The maximum air volume flows out of the
air vents for the upper body. Therefore, open
these vents for maximum cooling.
AUC Automatic recirculated-air
control/recirculated-air mode
You can respond to pollutants or
unpleasant odors in the immediate
environment by suspending the
supply of outside air. The system
then recirculates the air currently within the
vehicle. During AUC operation, a sensor
detects pollutants in the outside air and con-
trols the shut-off automatically.

Things to remember when driving
130 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.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
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 pressure on the brake pedal
can lead to high temperatures, brake wear and
possibly even brake failure.<
The braking effect of the engine can be further
increased by downshifting in the manual mode
of the automatic transmission, if necessary into
first gear, refer to page65. This prevents an
excessive strain on the brakes.
Do not drive in idle or with the engine
stopped, otherwise there will be no
engine braking action or support of the braking
force and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<
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 vehicle is parked
Condensation forms in the automatic climate
control system during operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page51,
otherwise they could be damaged due to the
width of the vehicle.
Release the parking brake, particularly when
you have activated Automatic Hold, refer to
page61.
General information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
Mixed tires*
Before driving into a car wash, make sure
that the vehicle width is not too large for
the car wash, as otherwise the vehicle and the
car wash could be damaged.<
Rear window wiper
The rear window wiper can be damaged in car
washes. Take appropriate protective measures;
ask the car wash operator if necessary.
With comfort access*
Insert the remote control into the ignition lock.
The engine can be switched off in transmission
position N, also refer to page37.

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.<
Make sure that no fluids leak in the cargo
bay; otherwise the vehicle could be dam-
aged.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
YYY lbs. or XXX kg. Otherwise, this could
damage the vehicle and produce unstable
vehicle operating 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 YYY lbs. or XXX kg.
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 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 occupants, the less cargo/luggage
can be transported.
Stowing cargo
>Load heavy cargo as far forward and as low
as possible, placing it directly behind the
backrest.
