2011 BMW 335I COUPE ECU

Driving
62 In the following situations, the 7-gear Sports
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 and SPORT
appears in the info display.

again automatically.
They are marked with the symbol

Deactivating DSC
Press the button for at least 3 seconds; the indi-
cator lamps for DSC in the instrument cluster
light up. Dynamic Traction Control DTC and
DSC have been simultaneously deactivated.
Stabilizing and drive-output promoting actions
are no longer executed.
In the same way as with a differential interlock
*,
even if DSC is deactivated, brake actions are
still performed to enhance drive output if the
drive wheels experience a significant loss of
traction.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button again; the indicator lamps in
the instrument cluster go out.
For better control
If the indicator lamp flashes:
DSC is regulating the drive and brak-
ing forces.
If the indicator lamps are on:
DSC is deactivated.
Dynamic Traction Control DTC
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:>When driving uphill on snow-covered roads,
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.
xDrive*
xDrive is your BMW's four-wheel-drive system.
The combined efforts of xDrive and DSC help to
further optimize traction and driving dynamics.
The xDrive four-wheel-drive system distributes
driving power variably to the front and rear axles
depending on the driving situation and road
conditions.

Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Coupe: head airbags
3Side airbags in the seat backrests
4Convertible: knee airbags
Protective action
Observe the adjustment instructions on
page42 to ensure the best possible per-
sonal protection.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.
The airbags have been designed to not be trig-
gered in every collision situation, e.g. not in
minor accidents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Keep the dashboard and windows on the front
passenger side clear, i.e. do not cover with
adhesive labels or coverings, and do not attach
holders such as for navigation instruments or
mobile phones.
Do not attach seat covers, cushions or other
objects not specifically approved for seats with
integral side airbags to the front seats. Do not
hang items of clothing such as coats or jackets over the backrests. Do not attempt to remove
the airbag retention system from the vehicle.
Do not modify the individual components of the
system or its wiring in any way. This includes
the upholstered covers on the steering wheel,
instrument panel, seats and roof posts, as well
as the sides of the roof lining. Do not attempt
to remove or dismantle the steering wheel.
Do not touch the individual components imme-
diately after the system has been triggered,
because there is a danger of burns.
In the event of malfunctions, deactivation or
triggering of the airbag restraint system, have
the testing, repair, removal and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to repair
procedures of BMW with correspondingly
trained personnel and that has the required
explosives licenses. Unprofessional attempts
to work on the system could lead to failure in an
emergency or to undesired airbag activation,
either of which could result in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the front
passenger airbags
An analysis of the impression in the front pas-
senger seat cushion determines whether and
how the seat is occupied. The front and side air-
bags for the front passenger are activated or
deactivated by the system accordingly.
The indicator lamp above the interior
rearview mirror shows the current status
of the front passenger airbags, deactivated or
