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
Up to 1,200 miles/2,000 km:
Drive at varying engine and driving speeds,
however do not exceed 4,500 rpm or 100 mph/
160 km/h in the process:
Always obey all official speed limits.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kick-down point.
Once you have driven 1,200 miles/2,000 km,
the engine and vehicle speeds 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
Approx. 300 miles/500 km must elapse 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 functio n of the clutch is als o only at its o pti-
mized level after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following component replacements
Observe the break-in instructions again if previ-
ously addressed components must be replaced
again during driving later.
General driving notes
Closing tailgate
Operate the vehicle only when the tail-
gate is completely closed, as 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
tailgate open:
1.Close all windows and the panorama glass
sunroof.
2.Greatly increase the air supply of the air
conditioner or automatic climate control,
refer to page56 or59.

Things to remember when driving
74 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
While driving in wet conditions and in heavy
rain, it is a good idea to 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 which
is generated by the brake applications 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 gradients in the gear in which
the least braking is required. Otherwise, even
light but consistent pedal pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can further enhance the engine's braking
effect by selecting a lower gear in the automatic
transmission's manual mode, downshifting as
far as first gear on extremely steep stretches,
refer to page37. This strategy helps you avoid
placing excessive loads on the brake system.
During slower downhill driving, use the HDC Hill
Descent Control, refer to page48.
Never drive with the clutch engaged, the
transmission in Neutral or with the engine
switched off, as otherwise there is no engine
braking when the transmission is in neutral, and
no power-assist for brakes and steering with
the engine switched off.
Never allow floor mats, carpets or other objects
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 air loss.<
Determining load limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX Ibs. or YYY kg, as 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.
