All indicator and warning lamps as well as dis-
plays in the instrument cluster go out.
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 or 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 cat-
alytic 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
page61.

vehicle tool kit, refer to page227, press the
red lever, see arrow, while moving the
selector lever to the desired position.
7-gear Sport automatic
transmission with double
clutch*
The concept
The 7-gear Sport automatic transmission with
double clutch is an automated manual trans-
mission with two clutches and secondary gear
sets in which the clutching and shifting is han-
dled by an electrohydraulic system.
With the 7-gear Sport automatic transmission
with double clutch, the gears are shifted without
an interruption in driving power.
You operate the 7-gear Sport automatic trans-
mission with double clutch using the selector
lever and two shift paddles on the steering
wheel.
It offers you the following functions:
>Either manual or automatic mode: sequen-
tial mode or drive mode
>Automatic downshifting and protection
against incorrect gear selection, even in
sequential mode
>Acceleration assistant, Launch Control,
refer to page66
>Automatic intermediate throttle application
System limitations
The 7-gear Sport automatic transmission with
double clutch has an overheating protection
that protects the clutch from extreme loads.
The indicator lamp lights up in yellow if
the transmission becomes too warm.
Avoid high engine loads and frequent
accelerations from zero. If the transmission is
overheated, the indicator lamp lights up in red
and the power flow to the motor is interrupted. It
is only possible to continue driving once the
transmission has cooled down.
Avoid frequent powerful accelerations from
zero and do not hold the vehicle on inclines by
pressing lightly on the accelerator while letting
the clutch slip, as this may cause the transmis-
sion to overheat.
Selector lever positions
P R N D M/S + –
The selector lever position and the engaged
gear are displayed, e.g. M4.
Engaging selector lever positions
>The selector lever can be moved out of
position P only with the engine running:
interlock.
>Before moving the lever away from P or N
with the vehicle stationary, first depress the
brake; otherwise, the desired shift will not
be executed: shiftlock.

Driving
64 The engaged gear, e.g. M1 is displayed in the
instrument cluster.
In the following situations, the 7-gear Sport
automatic transmission with double clutch
does the thinking for you:
>Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion of engine and vehicle speed; thus, for
example, a downshift that could cause the
engine to overrev will not be executed by
the system.
>At a stop, the transmission is automatically
shifted down to the first gear.
>Shortly before the speed falls below a gear-
dependent minimum speed, the transmis-
sion automatically downshifts without your
intervention.
Quick downshifting: even in sequential mode,
you can skip over several gears in order to
achieve an optimum acceleration. To do so,
depress the accelerator past the resistance
point.
To return to automatic mode, push the selector
lever to the right.
Gear shifting
Upshift or downshift using the selector lever or
the shift paddles. You do not need to lift your
foot off the accelerator when doing so.
Using the selector lever
>To upshift, pull the selector lever toward the
rear.
>To downshift, push it toward the front.
Using the shift paddles on the steering
wheel
You can also shift manually using two shift pad-
dles on the steering wheel. The shift paddles
allow you to shift gears quickly since both
hands can remain on the steering wheel.
>When you use the shift paddles on the
steering wheel to shift gears in automatic
mode, the transmission switches to manual
mode.>If you do not accelerate or shift gears using
the shift paddles for a certain amount of
time, the transmission switches back to
automatic mode if the selector lever is in
position D.
>To upshift, briefly pull the right shift
paddle +.
>To downshift, briefly pull the left shift pad-
dle –.
Driving dynamics control
The driving dynamics control permits you, at
the push of a button, to have your BMW react in
an even more sporty fashion when driving:
>Optimal use is made of the engine's speed
range.
>Gear changes occur more quickly.
>The engine reacts more spontaneously to
accelerator pedal movements.
Activating the system
Press the SPORT button.
The LED in the button lights up.

Things to remember when driving
116
Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed an engine speed of 4,500 rpm or a
road speed of 100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Saving fuel
The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicle serviced regularly.
Remove any unneeded cargo
Additional weight increases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove unneeded additional mirrors, the roof
rack and the rear luggage rack after use.
Mounted parts affect the vehicle's aerodynam-
ics and increase fuel consumption.
Close the windows and glass roof
An open glass roof or window causes higher air
resistance and thus increases fuel consump-
tion.
Check tire inflation pressure regularly
Check the tire inflation pressure 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 warm 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.

Things to remember when driving
118 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 page213.
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 page84.
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.
Objects in the movement range of the
pedals
Keep floor mats, carpet, and other objects
out of the movement range of the pedals;
otherwise, they may inhibit the function of the
pedals during driving.
Do not place additional floor mats onto an exist-
ing one or onto other objects.
Only use floor mats that have been approved for
the vehicle and can be appropriately fastened.
Make sure that the floor mats are securely fas-
tened again after they have been removed, e.g.
for cleaning.<
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 page61.
Sport automatic transmission with double
clutch never drive with the transmission in
neutral or with the engine switched off; other-
wise, there will be no engine 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 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
