General driving notes

Brakes: do not drive with your foot
resting on the brake pedal. Even

light but consistent pressure on the
brake pedal can lead to high tempera-
tures, accelerated brake wear and pos-
sibly even brake failure.
Hydroplaning: when driving on wet or
slushy roads, reduce your speed. If you
do not, a wedge of water may form
between tires and road surface. This
phenomenon can lead to partial or
complete loss of contact between the
tires and road surface, as well as loss of
vehicle control and braking ability.
Driving through water: do not drive
through water on the road if it is deeper
than 1 ft/30 cm, and then only at walk-
ing speed. Otherwise, the vehicle's
engine, the electrical systems and the
transmission may be damaged.
Rear parcel tray: never use it to store
heavy or hard objects, as otherwise
occupants could be injured during
braking maneuvers.
Clothes hooks: when hanging clothing
from the hooks, be sure that they will
not obstruct the driver's vision. Do not
hang heavy objects on the hooks. If you
do so, they could cause personal injury
during braking or evasive maneuvers.

Antilock Brake System (ABS)

The concept

ABS keeps the wheels from locking
during braking, thereby enhancing
active driving safety.

Braking with ABS

If you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply maxi-
mum pedal pressure – panic stop.
Since the vehicle maintains steering
responsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.

Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.

Dynamic Brake Control (DBC)

DBC is included in the DSC, refer to
page

83

.

The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest-possible braking
distances during 'panic stops'. This
system exploits all the benefits of ABS.

Do not reduce the pressure exerted
against the brake pedal until the brak-
ing maneuver has been completed.
DBC is deactivated when you release
the brake pedal.

Cornering Brake Control (CBC)

CBC is an advanced engineering devel-
opment of ABS. When braking during
cornering with high lateral accelera-
tion, or when braking during a lane
change, vehicle stability is improved
and the steering response is enhanced.
