ControlsTechnology for driving comfort and safety
In the same way as with a differential interlock,
even if DSC is deactivated, brake actions are
still performed on the rear axle to enhance drive
output if the drive whee ls experience a signifi-
cant loss of traction.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button again; th e indicator lamp in the
instrument cluster goes out.
For better control
If the indicator lamp flashes: the DSC
controls the driving and braking forces.
If the indicator lamp lights up: DSC and
DTC have failed.
The indicator lamp lights up and
DSC OFF is displayed in the instrument
cluster: DSC is deactivated.
Dynamic Traction Control DTC
DTC is a version of DSC in which the drive out-
put is optimized for part icular 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 sp ecial 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 lamp for DSC
OFF lights up and TRACTION is displayed in
the instrument cluster.
For better control
If the indicator lamp flashes: DTC con-
trols the driving and braking forces.
If the indicator lamp lights up: DSC and
DTC have failed.
The indicator lamp lights up and TRAC-
TION is displayed in the instrument
cluster: DTC is activated.
Deactivating DTC
Press the button again; th e indicator lamp in the
instrument cluster goes 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. <

ControlsTechnology for driving comfort and safety
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 speed range,
e.g. in a town or when parking, the steering
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 th e steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simult aneously deactivated
when DSC is switched off, refer to page 89.
Malfunction
The warning lamps come on. Active
steering is malfunctioning or is tem-
porarily deactivate d. At low speeds,
greater steering wheel movements
are required, whereas at higher speeds the
vehicle reacts more sensitively to steering
wheel movements. Th e stability-enhancing
feature may also be deactivated. Drive cau-
tiously and think well ahead.
Deactivation
Active steering is deacti vated to perform an ini-
tialization. A message indicates that the feature
is deactivated. Initializ ation 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 text mes-
sage appears. Have the system checked.
Servotronic
The concept
The Servotronic varies the steering force
required to turn the wh eels relative to the
vehicle 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
The warning lamp lights up. A mes-
sage appears on the Control Display.
Servotronic is malfunctioning or has
failed. Steering response will be different. You
can continue your journey, but moderate your
speed and exercise due caution. Have the
system checked as soon as possible.
Brake Force Display
On the left: normal braking.
On the right: sharp braking.
When the rear fog lamps are switched on, the
Brake Force Display is no t active and the illumi-
nated area for normal braking is reduced by
approximately half.

Things to remember when driving
Driving tips
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 br aking is required. Even
light but consistent brak e 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 nec-
essary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mo de of the automatic
transmission, refer to page 65.
Sport automatic transm ission with double
clutch: never drive with the transmission
in neutral or with the en gine switched off; other-
wise, there will be no en gine 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 driv en only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are le ss frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminan ts 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
climate 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 ca pacity, never over-
load the vehicle. Overlo ading can lead to over-
heating and increases the rate at which damage
develops inside the tires. In some situations,
this can result in sudden loss of tire pressure. <
Avoid fluid spills in the trunk as they could
damage the vehicle. <
Determining loading limit
1.Locate the following statement on your
vehicle's placard:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise damage to
the vehicle may occur and unstable driving
conditions may result.<
2. Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.
4. The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals

Care
Mobility
In order to prevent staining, e.g due to clothing,
clean the leather approximately every two
months.
Clean light-colored leather
more frequently as it
shows dust and dirt more noticeably.
Use BMW Premium Leather Care since dirt and
grease will otherwise slow ly affect the protec-
tive layer of the leather.
Suitable care products are available at your
BMW center.
Upholstery care
Regularly vacuum with a vacuum cleaner.
To remove severe spots such as beverage
stains, use a soft sponge or lint-free microfiber
cloth and suitable interior cleaners.
Clean the upholstery down to the seams using a
sweeping motion. Avoid strong rubbing.
Opened Velcro fasteners on pants or
other articles of clothing can damage the
seat covers. Ensure that Velcro fasteners are
closed. <
Care of special parts
Light-alloy wheels
When cleaning on the vehicle, use only neutral
rim cleaner with a pH value of 5 to 9. Do not use
coarse cleansers and do not use steam clean-
ers at temperatures greater than 140 7/60 6.
Follow manufacturer's instructions.
Aggressive, acid-containing, or strongly alka-
line cleaning agents can destroy the protective
coating of nearby components such as the
brake discs.
Chrome look surfaces
Carefully clean vehicle parts such as the radia-
tor grill or door handles with copious quantities
of water and possibly a shampoo additive, par-
ticularly when roads ar e treated with deicing
salt.
Rubber parts
Treat only with water or rubber care products.
Do not use silicon-containing care products on
rubber seals; otherwis e, noise and damage
could occur.
Fine wood parts
Clean fine wood trim an d fine wood parts only
with a damp cloth. Wipe dry with a soft cloth.
Plastic parts
These include:
>Imitation leather surfaces
> Roofliner
> Lamp glasses
> Display pane of instrument cluster
> Parts spray painted matte black
> Painted parts in the passenger
compartment
Use a microfibre cloth for cleaning.
Moisten the cloth slightly with water.
Do not soak the roofliner. Do not use any cleaners that contain alco-
hol or solvents such as lacquer thinner,
cold cleaning agents, fuel, and the like; other-
wise, you may damage the surfaces. <
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
Do not clean chemic ally, as this may
destroy the webbing. <
Only clean with a mild soap solution in the
installed state.
Only reel in seat belts when they are dry.
