If the clutch pedal is not depressed,
the motor will not start.<
3.Start the engine.
Automatic transmission
1.Step on the brake.
2.Move selector lever into position P.
3.Start the engine.
Special starting conditions
In the following situations, press the accelerator
pedal halfway down while starting:
>If the engine fails to start on the first
attempt, for instance, if it is very hot or cold.
>When starting the engine at very low tem-
peratures, below approx. +57/–156, at
high altitudes over approx. 3,300 ft/
1,000 m.
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 inadequately burned and there is
a danger of overheating and damaging the cat-
alytic converter.<
Switching off engine
Do not remove the ignition key when the
vehicle is rolling; otherwise, the steering
wheel lock would engage during steering.
When leaving the vehicle, remove the ignition
key and lock the steering. When parking on
downward inclines, engage the handbrake; oth-
erwise, the vehicle could start to roll.<
Manual transmission
1.Apply the handbrake.
2.Turn the ignition key to position 1 or 0.
3.Shift into first gear or reverse.
Automatic transmission
1.With the vehicle at a stop, move the selector
lever into position P.
2.Turn the ignition key to position 1 or 0.3.Apply the handbrake.
Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up; an acous-
tic signal also sounds when you begin
to drive. The handbrake is still engaged.
Indicator lamp for Canadian models.
Engaging
The lever engages automatically.
Releasing
Pull up slightly on the lever, press the button
and lower the lever.
If exceptional circumstances should
make it necessary to engage the hand-
brake while the vehicle is in motion, do not pull it
too strongly. In doing so, continuously press the
button of the handbrake lever. Otherwise,
strong application of the handbrake can lead to
overbraking of the rear axle and to associated
'fishtailing' of the vehicle rear end.<
To prevent corrosion and one-sided brak-
ing action, occasionally engage the hand-
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 hand-
brake is applied.<

Things to remember when driving
78
Safe braking
Your BMW is equipped with ABS as standard
equipment. In situations in which it is required, it
is best to apply the brakes fully. Since the vehi-
cle maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.
Pulsation at the brake pedal combined with
sounds from the hydraulic circuits indicates to
the driver that ABS is in its active mode.
Wet roads
On wet roads or in heavy rain, briefly apply light
pressure to the brake pedal every few miles.
Watch traffic conditions to ensure that this
maneuver does not endanger other road users.
The heat that is generated by the brake applica-
tions helps to dry the brake pads and rotors.
The full braking force will then be available
when you need it.
Hills
To prevent overheating and reduced effi-
ciency of the brake system, drive long or
steep downhill grades in the gear in which the
least braking is required. Otherwise, even light
but continuous pressure on the brake can lead
to high temperatures, brake wear and possibly
even brake failure.<
The braking action of the engine can be further
intensified by downshifting, all the way down to
first gear if need be. This strategy helps you
avoid placing excessive loads on the brake sys-
tem. Downshifting in manual mode of automatic
transmission, refer to page39. When descend-
ing hills slowly, use HDC Hill Descent Control,
refer to page49.
Never drive with the clutch depressed,
with the transmission in neutral, or with
the engine switched off; otherwise, you will
have neither the braking action of the engine or
nor its power assistance to the brakes or steer-
ing.
Never allow floor mats, carpeting, or other arti-
cles to protrude into the area around the brake
or accelerator pedals and obstruct their move-
ment.<
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 minimal
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.
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. The ultimate result
can assume the form of a sudden blow-out.<
Determining load limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, the vehicle
may be damaged and unstable driving con-
ditions may result.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.

Replacing components
106 Do not continue driving if the V-belt is
defective. The engine could be damaged
due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.<
Charging battery
Charge the battery in the vehicle only when the
engine has been switched off. For connections,
refer to Jump starting on page108.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always secure the
battery to prevent it from tipping over during
transport.<
Power failure
After a temporary power supply interruption,
some equipment is subject to limited use and
must be reinitialized. Individual settings are also
lost and must be updated again:
>Panorama glass sunroof
It may be only possible to raise the sunroof.
The system must be initialized, refer to
page23.
>Power windows
The pinch protection system must be reini-
tialized, refer to page22.
>Seat and mirror memory
The positions must be stored again, refer to
page29.
>Time
Must be set again, refer to page44.
Fuses
Never attempt to repair a blown fuse, and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating, as
this could lead to a circuit overload, ultimately
resulting in a fire in the vehicle.<
Open the glove compartment and turn the two
quick-release fasteners to the left, refer to
arrows.
Spare fuses, plastic tweezers, and information
about fuse allocation are stored with the fuses.
