A congenial climate
For almost all conditions, the AUTO program1
offers the optimal air distribution and air vol-
ume. Select an interior temperature that you
find pleasant.
The following section contains more detailed
information on the available setting options.
The settings are stored for the remote key cur-
rently in use.
AUTO program
The AUTO program handles the
adjustment of air distribution to the
windshield and side windows, in
the direction of the upper body, and in the foot-
well, as well as the adjustment of the air volume. It also adapts your instructions for the tempera-
ture to outside influences throughout the year.
The cooling is switched on automatically with
the AUTO program. At the same time, a con-
densation sensor controls the program so as to
prevent window condensation as much as pos-
sible.
Intensity of AUTO program
You can adjust the intensity of the AUTO pro-
gram by repeatedly pressing the AUTO button.
Press the button to have the current setting
briefly displayed on the lower status line of the

Automatic recirculated air control/
recirculated air mode
You can respond to unpleasant
odors or pollutants in the immedi-
ate environment by temporarily
suspending the supply of outside air. The sys-
tem then recirculates the air currently within the
vehicle. In AUC mode, a sensor detects pollut-
ants in the outside air and controls the shut-off
automatically.
Press the button repeatedly to run through the
following control sequence:
>LEDs off: outside air flows into the vehicle
continuously.
>Left LED on, AUC mode: the system
detects pollutants in the outside air and
responds by blocking the supply of outside
air when required.
>Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is con-
tinuously blocked.If the windows fog over in recirculated-air
mode, then press the AUTO button or
switch off the recirculated-air mode and
increase the air quantity as needed.
The recirculated-air mode should not be used
over a longer period of time, as the air quality
inside the vehicle deteriorates continuously.<
Automatic climate control, switching
on and off
The air volume, the heater, and the
air conditioner mode are all
switched off.
You can restart the automatic climate control by
pressing any of its buttons except the REST
button.
Temperature adjustment
Adjust the desired temperature
individually on the driver's side and
passenger side. Your settings
appear on the status line of the
Control Display.
The automatic climate control achieves this
temperature as quickly as possible at any time
of year, if necessary with the maximum cooling
or heating capacity, and then keeps it constant.
When switching between different tem-
perature settings in rapid succession, the
automatic climate control does not have suffi-
cient time to achieve the set temperature.<
The highest setting switches on the maximum
heat output regardless of the outside tempera-
ture. The lowest setting activates maximum air
conditioning.

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 phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between tires and
road surface, ultimately undermining your abil-
ity to steer and brake the vehicle.<
Driving through water
Only drive through water with a maximum
depth of 1 ft/30 cm and then, at no more
than walking speed. Otherwise, you run the risk
of damaging the vehicle's engine, electrical sys-
tems, and transmission.<
Safe braking
Your BMW is equipped with ABS as standard
equipment. In situations that require it, it is best
to apply the brakes fully. Since the vehicle
maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indicate to
the driver that ABS is in its active mode.
Driving in wet conditions
When driving in wet conditions and in heavy
rain, it is a good idea to apply light pressure to
the brake pedal every few miles. Monitor traffic
conditions to ensure that this maneuver does
not endanger other road users. The heat gener-
ated 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 reduced effi-
ciency of the brake system, drive long or
steep downhill grades in the gear that requires
the least amount of braking. Otherwise, even
light but consistent pedal pressure can lead to
high temperatures, brake wear, and possibly
even failure of the brake system. action by selecting a lower gear in the automatic
transmission's manual mode, downshifting as
far as first gear on extremely steep stretches,
refer to page63. This strategy helps you avoid
placing excessive loads on the brake system.
Do not drive in idle or with the engine
switched off; otherwise, there will be no
engine braking action or power-assist for the
brakes 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 minimal
pressure that must be exerted by the pads dur-
ing 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 during operation, and then exits under
the vehicle. Traces of condensed water under
the vehicle are therefore normal.
Before driving into a car wash
1.Fold in the exterior mirrors, refer to page50;
otherwise, they could be damaged due to
the width of the vehicle.
To permit the vehicle to roll, follow the
instructions on page58.
2.Release the parking brake, especially when
you have activated Automatic Hold. Refer to
page59.

Wheels and tires
Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check tire inflation pressure when the tires
are cold. This means after a maximum of
1,25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly
and correct it as needed, including the
spare wheel: at least twice a month and before
starting long trips. If you fail to take this precau-
tion, you may be driving on tires with incorrect
tire pressures, a condition that can not only
compromise your vehicle's driving stability, but
also lead to tire damage and the risk of an acci-
dent. Do not drive with deflated, i.e. flat tires,
except run-flat tires. A flat tire will seriously
impair your vehicle's handling and braking
response. Attempts to drive on a flat tire can
lead to loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page90, or reset the Tire Pressure Monitor,
refer to page92.<
Pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes and tire brands respectively
approved and recommended by BMW; a list of
these is available from your BMW center.<
For correct identification of the right inflation
pressure for your tires, pay attention to the fol-
lowing:>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column for traveling speeds up to a max. of
100 mph/160 km/h to achieve optimum driving
comfort.
These pressure specifications can be found on
the door post when you open the driver's door.
The permissible top speed for these tire
inflation pressures is 100 mph/160 km/h.
Do not exceed this speed; otherwise, tire dam-
age and accidents may result.<
Tire inflation pressures for driving
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please
consult the relevant table on the following
pages and adjust tire pressures as necessary to
the specified pressures for speeds exceeding
100 mph/150 km/h. Otherwise, tire damage
and accidents could occur.<
Observe all national and local maximum speed
limits; otherwise, violations of the law could
occur.

Wheels and tires
204
Temperature
The temperature grades are A, B, and C, A
being highest, and represent the tire's resis-
tance to the generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC Run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page205.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread depth,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not fall below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm.
At tread depths below 0.12 in/3 mm, there is an
increased risk of high-speed hydroplaning,
even when only small amounts of water are
present on the road surface.
Winter tires display a noticeable loss in their
ability to cope with cold-weather driving condi-
tions once the tread wears to below 0.16 in/
4 mm. To ensure continued safety, you should
always have such tires replaced.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has been driven down to the wear indicators, a
tread depth of 0.063 in/1.6 mm has been
reached.
Wheel/tire damage
Please note that low profile tires make wheels,
tires, and suspension parts more susceptible to
road hazards and consequential damages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. Drive carefully to the nearest
BMW center or tire shop that works according
to BMW repair procedures with correspond-
