Starting the engine
Do not run the engine in enclosed areas;
otherwise, the inhalation of toxic exhaust
gases can cause loss of consciousness and
death. The exhaust gases contain carbon mon-
oxide, an odorless and colorless, but highly
toxic gas. Never leave an unattended vehicle
with the engine running; otherwise, such a vehi-
cle represents a potential safety hazard.
Before leaving the car with the engine running,
place the transmission in neutral or move the
selector lever to position P and forcefully apply
the parking brake to prevent the car from mov-
ing.<
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in
which the engine does not start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter.<

Parking brake
The parking brake is primarily intended to pre-
vent the vehicle from rolling while parked; it
brakes the rear wheels.
Indicator lamp
The indicator lamp is lit, and when you
drive off a signal sounds in addition.
The parking brake is still applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
In exceptional cases, if the parking brake
has to be used to slow or stop the car, do
not pull the lever up too hard. In doing so, con-
tinuously press the button of the parking brake
lever.
Otherwise, excessive force on the parking
brake can lock up the rear wheels and cause the
rear of the car to swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the parking
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the park-
ing brake is applied.<
Manual transmission
When shifting into 5th or 6th gear, press
the gearshift lever to the right. Otherwise,
the engine could be damaged if you inadvert-
ently shift into 3rd or 4th gear.<
Reverse gear
Select this only when the vehicle is stationary.
When the gearshift lever is pressed to the left, a
slight resistance has to be overcome.
Automatic transmission with
Steptronic*
In addition to fully automatic operation, you can
also manually shift with the Steptronic, refer to
page50.
Vehicle parking
To prevent the vehicle from rolling,
always select position P and apply the
parking brake before leaving the vehicle with
the engine running.<
Disengaging the remote control
In order to remove the remote control from the
ignition lock, you must first move the selector
lever to position P and switch off the engine:
interlock. Removing the remote control from
the ignition lock, refer to page47.

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.<

Active steering*
The concept
Active steering varies the turning angle of the
front wheels in relation to steering wheel move-
ments. It also varies the steering force required
to turn the wheels depending on the speed at
which you are driving.
When you are driving in the low road speed
range, e.g. in a town or when parking, the steer-
ing angle is increased, i.e. steering becomes
very direct and less effort is required to turn the
wheels. In the higher speed range, on the other
hand, the steering angle is reduced as the
speed increases. This improves the handling of
your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page65.
Malfunction
The warning lamps come on. Active
steering is malfunctioning or is tem-
porarily deactivated. At low speeds,
greater steering wheel movements
are required, whereas at higher speeds the
vehicle reacts more sensitively to steering
wheel movements. The stability-enhancing
feature may also be deactivated. Drive cau-
tiously and think well ahead.
Deactivation
Active steering is deactivated to perform an ini-
tialization. A message indicates that the feature
is deactivated. Initialization may take several
minutes.
If the message does not disappear during the
current trip, have the system checked.
Defect
If there is a defect, a corresponding message
appears. Have the system checked.
Servotronic*
The concept
The Servotronic varies the steering force
required to turn the wheels relative to the vehi-
cle speed.
At low speeds, the steering force is strongly
assisted, i.e. less force is needed for steering.
As the vehicle speed increases, the steering
assisting power is reduced.
This system functions automatically.
Malfunctions
Malfunctions are displayed via Check Control,
refer to page62.

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

cantly to the value retention of your BMW.
BMW recommends cleaning and caring for your
vehicle with products that are approved by
BMW for this purpose.
Your BMW center will be happy to advise you on
the products and services available for cleaning
and caring for your BMW.
Original BMW CareProducts have been
material tested, laboratory checked and
proven in the field, and offer optimal care and
protection for your vehicle.<
Do not use cleaners that contain alcohol
or solvents as these may result in dam-
age.<
Cleaning agents can contain substances
that are dangerous or hazardous to your
health. Therefore, follow the warning and safety
instructions on the packaging. When cleaning
inside the vehicle, always open the doors or
windows of the vehicle. In enclosed areas, pro-
vide for sufficient ventilation. Only use products
designed for cleaning vehicles.<
Exterior care
Washing the vehicle
Especially during the winter months,
ensure that the vehicle is washed more
frequently. Heavy soiling and road salt can lead
to vehicle damage.<
After washing the vehicle, apply the
brakes briefly to dry them; otherwise,
water can reduce braking efficiency over the
short term and brake discs can corrode.<
Automatic car washes
Preference should be given to cloth car washes.Do not use high-pressure car washes;
otherwise, water may drip into the vehicle
around the windows.<
Before driving into a car wash, ensure that it is
suitable for your BMW. Check the following:
>Dimensions of your vehicle, refer to
page147.
>If necessary, fold in the outside rearview
mirrors, refer to page42.
>Maximum permissible tire width.
Avoid car washes with guide rail heights
over 4 in/10 cm; otherwise, there is the
danger of damaging chassis parts.<
>In Convertibles, do not treat the convertible
top with wax. Ensure that a program is avail-
able that does not apply wax or is designed
specifically for convertibles.
Preparations before driving into an automatic
car wash:
>Unscrew the rod antenna
*.
>Deactivate the rain sensor
* to prevent unin-
tentional wiping.
>Remove additional attachments, e.g. spoil-
ers or telephone antennas, if there is a pos-
sibility that they could be damaged.
Automatic transmission
Before driving into an automatic car wash, per-
form the following steps to ensure that the vehi-
cle can roll:
1.Insert the remote control into the ignition
lock, even with Comfort Access.
2.Engage transmission position N.
3.Release the parking brake.
4.Switch off the engine.
5.Leave the remote control in the ignition lock

Changing wheels
Your BMW is equipped with run-flat tires as
standard. This removes the need to change a
wheel immediately in the event of a puncture.
For information on continuing to drive with a
damaged tire, refer to Indication of a flat tire on
page67.
The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall, refer to
Run-flat tires, page112.
