2009 BMW M5 SEDAN engine overheat

Driving
58
Radio readiness and ignition switched
off
All indicator and warning lamps in the instru-
ment cluster go out.
Starting the 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.
Before leaving the vehicle with the engine run-
ning, shift into neutral
* or move the selector
lever into position N and firmly apply the hand-
brake, otherwise the vehicle can begin to roll.<
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.<
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive at a moderate engine
speed.
Manual transmission*
Remote control in ignition lock or with comfort
access in vehicle, refer to page38.
1.Depress brake pedal.
2.Depress the clutch pedal and shift into
idling position.
3.Press the Start/Stop button.
Sequential Manual Transmission with
Drivelogic
Remote control in ignition lock or with comfort
access in vehicle, refer to page38.
1.Firmly apply the handbrake.
2.Depress brake pedal.
3.Place selector lever in position N.
4.Press the Start/Stop button.
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 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.<
After every engine start, the Sequential mode is
activated in Drivelogic driving program 3 when
the selector lever is pushed to the right into
drive positionΒ and the brake pedal is pressed.
Switching off engine
When leaving the vehicle, always take the
remote control with you.
When parking, firmly apply the handbrake, as
otherwise the vehicle could roll.<
Manual transmission*
1.Press the Start/Stop button with the vehicle
stopped.
2.Shift into first gear or reverse.
3.Firmly apply the handbrake.
4.Remove the remote control from the igni-
tion lock, refer to page57.
Sequential Manual Transmission with
Drivelogic
1.Firmly apply the handbrake.
2.Shift into a driving position.
3.Press the Start/Stop button.
If N is engaged when switching off the
engine, this will be pointed out to you opti-
cally and acoustically.

1.Hold the vehicle with the brake.
2.Release the brake and begin to drive imme-
diately.
After releasing the brake, begin to drive
immediately; otherwise, the starting
assistant no longer holds the vehicle after
approx. 2 seconds and your vehicle will start to
roll backward.<
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 the "P 400" program of M Engine
Dynamic Control, refer to page60.
2.Gently press accelerator pedal to prevent
wheels from spinning when starting off.
Clutch protection with manual
transmission
Be sure to avoid riding the clutch for longer peri-
ods.
Your BMW M5 is equipped with an overload
protection for the clutch. Riding the clutch for
longer periods is detected and the engine man-
agement system limits the engine speed to pro-
tect the clutch. This can result in the vehicle fail-
ing to accelerate when the clutch pedal is
partially depressed.
EDC Electronic Damping
Control
The concept
If the influencing variables such as road surface
quality or operating conditions such as steer-
ing, braking etc. change, the damping automat-ically adjusts to the new conditions within a
fraction of a second.
You can choose from three programs.
"Comfort" program
Select the "Comfort" program if you want com-
fort-oriented coordination of shock absorbers
and steering.
"Normal" program
The "Normal" program offers control that is bal-
anced between comfort and sportiness.
"Sport" program
Select the "Sport" program if you want a con-
sistently sporty coordination of shock absorb-
ers and steering.
Selecting program
Sequential Manual Transmission with Drive-
logic:
Manual transmission:
Press the EDC button repeatedly:
>"Comfort": LED off.
>"Normal": one LED lights up.
>"Sport": both LEDs light up.

etc. Such contact could lead to a fire, and with it
the risk of serious property damage as well as
personal injury. Do not touch hot exhaust tail
pipes. Otherwise there is a risk of burns.<
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.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, refer also to Mini-
mum tire tread on page206.
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.<
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 can
lead to high temperatures, brake wear and pos-
sibly even brake failure.<
Sequential Manual Transmission: 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 steer-
ing.
Manual transmission: do not drive with the
clutch depressed, 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
