Things to remember when driving
Breaking-in
Moving parts should be allowed to adjust to one
another. To ensure that your vehicle provides
maximum economy throughout a long service
life, we request that you observe the following
instructions.
Engine and differential
Always obey all official speed limits.
For the first 1,200 miles/2,000 km
Drive at varying engine and driving speeds, but
do not exceed 4,500 rpm or 100 mph / 160 km/h
in the process.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kick-down point.
After 1,200 miles/2000 km
Engine and road speed 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. For this reason, drive with extra care
during the initial 200 miles/300 km.
Obey your local and state maximum speed lim-
its.
When the vehicle is operated on wet or
slushy roads, a wedge of water may form
between the tire and the road surface. This phe-
nomenon is referred to as hydroplaning and can
lead to partial or complete loss of traction, vehi-
cle control and braking effectiveness. Reduce
your speed on wet roads.<
Brake system
Your vehicle must travel approx. 300 miles/
500 km before the brake pads and rotors
achieve the optimal pad-surface and wear patterns required for trouble-free operation and
long service life later on.
To break in the separate handbrake drums,
apply the handbrake lightly when coasting to a
stop – at a traffic signal, for instance; use cau-
tion to avoid posing a danger to other road
users.
To avoid corrosion, repeat this procedure from
time to time.
The brake lamps do not come on when the
handbrake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the vehicle
with the engine off – e.g., by towing – substan-
tially higher levels of pedal force will be required
to brake the vehicle.<
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 component replacements
Follow the break-in sequence again if compo-
nents addressed above must be replaced due
to subsequent driving.
General driving notes
Close the liftgate
Operate the vehicle only when the liftgate
is completely closed; otherwise, exhaust
fumes could enter the interior of the vehicle.<
If special circumstances should make it abso-
lutely necessary to operate the vehicle with the
liftgate open:

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.
