2006 BMW M5 SEDAN engine overheat

Driving

Starting engine
Do not run the engine in closed rooms,
otherwise the inhaling 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.
Before leaving the vehicle with the engine run-
ning, move the selector lever into the N position
and set the handbrake, otherwise the vehicle
can begin to roll.<
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive immediately at a moder-
ate engine speed.
Do not press the brake pedal as long as
you do not want to start the engine. The
engine starts immediately when you briefly
press the Start/Stop button with the brake
pedal depressed.<
1.Depress brake pedal.
2.Place selector lever in position N.
3.Briefly press 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.If the engine does not start, shift back to
the last selector lever position selected,
refer to the instrument cluster display or the
selector lever. Then select the position N.
You cannot start off with the hood open.
When the engine is cold, the exhaust system
has a slightly metallic undertone due to the sys-
tem design.<
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.<
Special starting conditions
Depress the accelerator pedal half way when
starting the engine in the following situations:
>The engine fails to start on the first attempt,
e.g. if it is very hot or cold.
>The engine is started at very low tempera-
tures, below approx. + 57/– 156, at high
altitudes, over approx. 3,300 ft/1,000 m.
Switching off engine
Do not remove the remote control from
the ignition lock while the vehicle is roll-
ing, otherwise the steering wheel lock would
engage while steering.
When leaving the vehicle, always take the
remote control with you.
When parking on a downhill incline, apply the
handbrake, as otherwise the vehicle could roll
away.<
1.Apply the handbrake.
2.Engage a driving position.
3.Briefly press the Start/Stop button.
A signal sounds when the position N is
engaged and the handbrake is not set when
switching off the engine.

the risk of serious property damage as well as
personal injury.<
Mobile communications devices in
vehicle
BMW discourages the use of mobile
communications devices, e. g. mobile
phones, inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Interior and exterior mirrors,
automatic dimming feature*
This feature is controlled by two photocells in
the inside rearview mirror. One is integrated into
the glass of the mirror, while the other is located
at an offset position on the rear of the mirror
housing.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach stickers of any kind to the windshield
in front of the mirror, either.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and
the road surface, ultimately undermining your
ability to steer and brake the vehicle. depth of the tires decreases, refer also to Mini-
mum tire tread on page178.
Driving through water
Do not drive through water on the road if it
is deeper than 1 ft/30 cm, and then only at
walking speed at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the
transmission may be damaged.<
Starting off
On slopes
The starting assistant enables starting off on
slopes virtually without rolling back.
1.Hold the vehicle with the footbrake.
2.Make sure that the handbrake is released.
3.Release the footbrake and immediately
drive off quickly.
The starting assistant holds the vehicle
for approx. 1 second after releasing the
footbrake. Depending on the load, the vehicle
m a y a l s o ro l l b a ck s li g h t ly d u ri n g t h is t im e . A f t er
releasing the footbrake, immediately start
quickly, otherwise the starting assistant no
longer holds the vehicle after approx. 1 second
and it begins to roll back.<
Start off quickly on slopes. Do not hold
the vehicle on a hill by pressing the accel-
erator, but apply the footbrake or handbrake
instead. Otherwise overheating and heavy wear
can result in the area of the Sequential Manual
Transmission.<
To protect the clutch of the Sequential Manual
Transmission from overheating, the starting-off
behavior is changed under heavy loading, e.g. a
rapid succession of starts on slopes. This can
be noticed from shaking during starting off.
On a slippery surface
1.Select program "P 400" of M Engine
Dynamic Control, refer to page58.
2.Gently press accelerator pedal to prevent
wheels from spinning when starting off.

Things to remember when driving
106
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
The pulsing of he brake pedal indicates that the
ABS is controlling braking.
In certain braking situations the perforated
brake rotors can cause operating noises which,
however, have not effect on the performance
and operating safety of the brake system.
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.<
Do not drive in idle or with the engine
switched off, 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 air conditioner sys-
tem 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 page46,
otherwise they could be damaged due to the
width of the vehicle.
General information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
Ground clearance
Ensure that sufficient ground clearance
is available. To drive down curbs, select
the "Sport" program of the EDC Electronic
Damping Control, refer to page76, to keep the
ground clearance as uniform as possible.
Otherwise the vehicle may be damaged.<
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.<
