2008 BMW 4.8I overheating

Driving
60
Starting engine
Do not run the engine in closed rooms,
otherwise the inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, as such a vehicle represents a
potential safety hazard.
To prevent the vehicle from rolling, always
engage transmission position N or P and set the
parking brake before leaving the vehicle with
the engine running.<
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, drive off at a moderate engine speed.
The engine starts when you depress the
brake pedal while pressing the Start/Stop
button.<
Avoid frequent starting in quick succes-
sion or repeated starting 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 catalytic converter.<
Remote control in ignition lock or with comfort
access in vehicle, refer to page36.
1.Depress brake pedal.
2.Press the Start/Stop button.
The system responds by automatically engag-
ing the starter for a certain period and automat-
ically disengaging it as soon as the engine
starts.
Switching off engine
When leaving the vehicle, always take
along the remote control.
Set the parking brake firmly when parking; oth-
erwise, the vehicle could roll.<
Procedure
1.Engage transmission position P with the
vehicle stopped.
2.Press the Start/Stop button.
3.Set the parking brake.
4.Remove the remote control from the igni-
tion lock, refer to page59.
Before driving into a car wash
The vehicle can roll if you proceed according to
the following steps:
1.With comfort access
*: insert the remote
control into the ignition lock.
2.Depress brake pedal.
3.Engage transmission position N.
4.Release the parking brake or deactivate
Automatic Hold.
5.Switch off the engine.
Transmission position P will be engaged:
>automatically after approx. 30 minutes
>if you remove the remote control from the
ignition lock
Parking brake
The concept
Your BMW is equipped with an electromechan-
ical parking brake.
The parking brake is primarily intended to pre-
vent the vehicle from rolling while parked.
You can use the parking brake in two ways:
>manually, by pulling and pushing the button
>automatically, by activating Automatic
Hold, refer to page61

Things to remember when driving
130 possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
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 braking is required. Even
light but consistent pressure on the brake pedal
can lead to high temperatures, brake wear and
possibly even brake failure.<
The braking effect of the engine can be further
increased by downshifting in the manual mode
of the automatic transmission, if necessary into
first gear, refer to page65. This prevents an
excessive strain on the brakes.
Do not drive in idle or with the engine
stopped, otherwise there will be no
engine braking action or support of the braking
force and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<
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 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 vehicle is parked
Condensation forms in the automatic climate
control system during operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page51,
otherwise they could be damaged due to the
width of the vehicle.
Release the parking brake, particularly when
you have activated Automatic Hold, refer to
page61.
General information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
Mixed tires*
Before driving into a car wash, make sure
that the vehicle width is not too large for
the car wash, as otherwise the vehicle and the
car wash could be damaged.<
Rear window wiper
The rear window wiper can be damaged in car
washes. Take appropriate protective measures;
ask the car wash operator if necessary.
With comfort access*
Insert the remote control into the ignition lock.
The engine can be switched off in transmission
position N, also refer to page37.
