Driving Through Water; Starting Off - BMW 2008 M6 Owner's Manual

Hot exhaust system
As in all vehicles, extremely high temper-
atures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to it, and never apply undercoating to
them. When driving, standing at idle and while
parking, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
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
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
The risk of hydroplaning increases as the tread
depth of the tires decreases, also refer to Mini-
mum tire tread on page 205.

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 you to start off
conveniently on slopes. The handbrake is not
required for this purpose.
1. Hold the vehicle with the footbrake.
2. Release the footbrake and drive off quickly.
The starting assistant holds the vehicle
for approx. 1 second after releasing the
footbrake. After releasing the footbrake, drive
off quickly, otherwise the starting assistant no

vehicle.<
Be sure to avoid riding the clutch for longer peri-
ods.
Your BMW M6 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.
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.
