Kickdown:
For rapid acceleration, e.g. during passing,
depress the accelerator pedal completely. You
achieve maximum acceleration.
To switch back to sequential mode: tap the
selector lever again to the right toward D, or
change the current gear via the shift paddles or
the selector lever.
When driving off on inclines, drive
smoothly without pausing. Do not keep
the vehicle in place by depressing the accelera-
tor pedal; instead, apply the parking brake. Oth-
erwise, the gearbox could overheat.<
Shifting gears
With selector lever
>To upshift, tap the selector lever toward +
>To downshift, tap the lever toward –.
With shift paddles on steering wheel
>To upshift, pull one of the shift paddles
>To downshift, push the paddle.
In the following situations, the SMG in the
sequential mode assists you:
>The transmission will only execute upshifts
and downshifts that will result in an appro-
priate combination of vehicle speed and
engine rpm. For instance, downshifts that
would result in excessive engine speed
cannot be executed
>During a stop the gearbox is automatically
downshifted into first gear
>Shortly before a gear-dependent minimum
speed is reached, the gearbox automatically
shifts down without you taking any action.
Malfunction
The warning lamp lights up. The trans-
mission system is malfunctioning.
Avoid heavy loads.
All of the selector lever positions can continue
to be engaged; in the forward drive positions,
however, the vehicle will be operating in a
restricted gear range only. Have the system
checked as soon as possible.
Towing and tow-starting, refer to page98;
Jump starting, refer to page97.
Overheating
An acoustic warning signal sounds. The gear-
box is overheating. If possible, stop the vehicle
or drive off swiftly so that the system can cool
off again.
Driving Dynamic Control
Driving Dynamic Control allows your BMW to
react in a sportier driving style at the touch of a
button:
>The engine responds more spontaneously
to any motion of the accelerator pedal
>The vehicle is steered more directly and
traction is enhanced
>Cruise control:
When the speed last stored is called up, this
speed is attained more quickly.
Additional features with SMG:
>Gears are shifted more quickly
>The engine speed range is optimally utilized
in the drive mode.
With automatic transmission:
>The Sport program is activated.

damaged.<
Windshield washer nozzles
The windshield washer nozzles are automati-
cally heated
* when the engine is running or the
ignition is switched on.
Cruise control*
Do not use cruise control when unfavor-
able conditions make it inadvisable to
drive at a constant speed. Otherwise, the vehi-
cle could go out of control and an accident
could be caused. Unfavorable conditions
include, for example, twisting roads, high traffic
density, or adverse road conditions such as
snow, rain, ice, or loose surfaces.<

3To recall the stored speed
4To deactivate the system
To maintain, store and increase speed
Above approx. 20 mph / 30 km/h you can main-
tain and store any desired speed.
Press the lever briefly in direction 1:
The system maintains and stores the current
vehicle speed. Every time you tap the lever, the
speed increases by approx. 0.6 mph / 1 km/h.
Hold the lever in position1:
The vehicle accelerates without pressure on
the accelerator pedal. As soon as you release
the lever, the system stores and maintains the
current speed.
If, on a downhill grade, the engine braking
effect is not sufficient, the controlled
speed can be exceeded. Speed can drop on
uphill grades if the engine output is insuffi-
cient.<
To maintain, store and decrease speed
Press the lever briefly in direction 2:
When the cruise control is active, vehicle speed

is reduced by approx. 0.6 mph / 1 km/h every
time you tap the button.
Hold the lever in position2:
With the cruise control active, the system auto-
matically reduces the throttle opening to slow
the vehicle. As soon as you release the lever,
the system stores and maintains the current
speed.
To recall the stored speed
Press the lever briefly in direction 3:
The vehicle accelerates to and maintains the
last speed stored.
To deactivate the system
Press the lever briefly in direction 4:
The cruise control is deactivated immediately.
In addition, the system is automatically deacti-
vated in response to the following conditions:
>When you apply the brakes
>When you depress the clutch or move the
automatic selector lever from D to N
>If you exceed or fall below the preset speed
for an extended period, for example by
depressing the accelerator
>If DSC is in action.
You can recall the speed last stored.
Cruise control is also deactivated when the igni-
tion key is turned to position 0.
The stored speed is cleared in this case.
