in slush or on unplowed, snow-covered
roads
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
Activating DTC
Press the button; the indicator lamps for DTC in
the instrument cluster come on.
For better control
If the indicator lamp flashes:
DTC is regulating the drive and braking
forces.
If the indicator lamps are on:
DTC has been activated.
Deactivating DTC
Press the button again; the DTC indicator
lamps in the instrument cluster go out.
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
1.Hold the car in place by depressing the
brake.
2.Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Otherwise, the drive-off assistant will no longer hold the car in place
after approx. 2 seconds and the car will start to
roll backwards.<
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<

function, this control is located at position 4.
Air distribution
Direct the flow of air to the win-
dows , to the upper body area
or to the footwell . Intermedi-
ate settings are possible.
Recirculated-air mode
If the air outside the car has an
unpleasant odor or contains pollut-
ants, shut off the supply to the
interior of the car temporarily. The
system then recirculates the air currently within
the vehicle.
You can also activate/deactivate the recircu-
lated-air mode by means of a button
* on the
steering wheel, refer to page11.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air volume as
required.
The recirculated-air mode should not be used
continuously for lengthy periods; otherwise, the
quality of the air inside the car will gradually
deteriorate.<
Air volume
Turn to adjust the air volume. The
higher the volume, the more effec-
tive the heating or cooling will be.
The air volume may be reduced or
the blower may be switched off entirely to save
on battery power.
Switching the system on/off
Set any desired air volume to switch on the air
conditioner.
Turn the air volume rotary switch to 0. The
blower and air conditioner are completely
switched off and the air supply is cut off.
The outside air supply is blocked when
the air conditioner is switched off. If the air
quality deteriorates or the window fogs over,
switch the system back on and increase the air
volume.<
Switching the 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.

AUTO program
Press the button.
Air volume, air distribution and
temperature are controlled auto-
matically.
Depending on the selected temperature, AUTO
intensity and outside influences, the air is
directed toward the windshield, the side win-
dows, the upper body and the footwell.
Pressing the AUTO button automatically
switches on the cooling function.
At the same time, a condensation sensor con-
trols the program so as to prevent window con-
densation as much as possible.
The program is switched off when the air distri-
bution is set manually or the button is pressed
again.
Intensity of the AUTO program
With the AUTO program switched on, auto-
matic control of the air volume and air distribu-
tion can be adjusted:
Press the left side of the button to
reduce the intensity. Press the
right side of the button to increase
it.
The selected intensity is shown on the display
of the automatic climate control.
Convertible program
The Convertible program is active when the
convertible top is open.
Adjusting air volume manually
To be able to manually adjust the air volume,
switch off the AUTO program first.Press the left side of the button to
reduce the air volume. Press the
right side of the button to increase
it.
The air volume may be reduced or the blower
may be switched off entirely to save on battery
power. The display remains the same.
Automatic recirculated-air control
AUC/Recirculated-air mode
You can respond to unpleasant odors or pollut-
ants in the immediate environment by tempo-
rarily suspending the supply of outside air. The
system then recirculates the air currently within
the vehicle.
Press the button repeatedly to
select an operating mode:
>LED off: outside air flows in continuously.
>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air and
controls the shut-off automatically.
>Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. If the windows fog over, switch off
recirculated-air mode and increase the air
volume, if necessary. Make sure that air can
flow onto the windshield.
The recirculated-air mode should not be
used continuously for lengthy periods;
otherwise, the quality of the air inside the car
will gradually deteriorate.<
Via the button on the steering wheel
You can switch quickly between the recircu-
lated-air mode and the previous mode using a
button
on the steering wheel, refer to page11.
ALL program
Press the button.
The current temperature setting
on the driver's side is transferred to
the front passenger side.

Coupe: ski bag*
The ski bag is designed for safe, clean transport
of up to 4 pairs of standard skis or up to
2snowboards.
With the ski bag you can stow skis with a length
of up to 6.6 ft/2.0 m. When skis of 6.6 ft/2.0 m
length are loaded, the overall capacity of the ski
bag is reduced due to its tapered design.
Loading
Ensure that the skis are clean when they are
loaded into the ski bag. Wrap sharp edges to
prevent damage.
1.Fold down the center panel in the rear seat
backrest.
2.Press the button, reach into the recess and
fold down the cover. To stabilize the cover
in the folded-down position, place the cen-
ter panel underneath it.
3.Open the Velcro fastener, spread the ski
bag between the front seats and insert the
skis or snowboards.
The zip fastener makes objects in the ski
bag easier to reach.
4.Attach the hook of the ski bag retaining
strap to the eyelet on the side of the ski bag
opening.
Securing cargo
After loading, secure the ski bag and its con-
tents. Tighten the retaining strap on the ten-
sioning buckle for this purpose.
Secure the ski bag in the manner
described; otherwise, it could endanger
the car's occupants, e.g. in case of heavy brak-
ing or sudden swerving.<
To store the ski bag, perform the steps
described for loading in reverse order.
Removing the ski bag
The ski bag can be completely removed, e.g. for
fa ster drying or to allow you to use other inserts.
1.Fold down the center panel in the rear seat
backrest.
2.Pull the handle, arrow1.
3.Pull out the insert, arrow 2.

Drive defensively
Avoid unnecessary acceleration and braking
maneuvers. To do so, keep an adequate dis-
tance between you and the 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, 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.
O n a d o w n h il l s lo p e , t a k e y o u r f o o t o f f t h e a c c el -
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 trunk lid
Operate the vehicle only when the trunk
lid is closed. Otherwise, exhaust fumes
could enter the interior of the vehicle.<
If the vehicle must be driven with the trunk 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.
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
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.

Things to remember when driving
98
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.
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 blowout.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
