Anti-lock brake system (ABS)
The ABS continuously monitors the
wheel speed. When the wheels are
about to be locked, the ABS system
repeatedly modulates the hydraulic
brake pressure to the wheels.When you depress brake pedals in
conditions, which may lock the
wheels, you may hear a snapping
sound or feel like that from the
brakes. This is normal and indicates
your ABS is active.
In order to obtain the maximum ben-
efit from your ABS in an emergency
situation, do not attempt to modulate
your brake pressure or to pump your
brakes. Press your brake pedal as
hard, as possible, or as the situation
allows, in order for the ABS to control
the power delivery to the brakes.
Information
A clicking sound may be heard in the
engine compartment, when the engine
is started, and the vehicle begins to
move. These conditions are normal
and indicate that the anti-lock brake
system properly operates.
Even with the anti-lock brake sys-
tem, your vehicle still requires a
safe braking distance. Always
maintain a safe distance from the
vehicle in front of you.
Always slow down the speed when cornering. The anti-lock brake sys-
tem cannot prevent accidents
resulted from an excessively high
speed.
On loose or uneven road surfaces, operation of the anti-lock brake
system may result in a longer brak-
ing distance than the one of a vehi-
cle equipped with a conventional
brake system.
i
5-26
Driving your vehicle
ABS (or ESC, Electronic
Stability Control system) can-
not prevent accidents caused
by improper or dangerous driv-
ing maneuvers. Even though
you have more control over the
vehicle with emergency brak-
ing, always maintain a safe dis-
tance between you and objects
ahead. Vehicle speeds should
always be reduced in extreme
rough road conditions. The
braking distance of an ABS(or
ESC)-equipped vehicle may be
longer than the one of a ABS-
unequipped vehicle in the fol-
lowing road conditions. In these
conditions the vehicle should
be driven at a reduced speed:
A road surface is rough, or it is covered with gravel or
snow
Tire chains are installed
The road surface is pitted or uneven.
The safety performance of an
ABS(or ESC)-equipped vehicle
should not be tested by driving
at a high speed or cornering.
This may put you and others in
danger.
WARNING

When the ABS warning light illu-minates and remains ON, your
vehicle may have a problem with
the ABS. In this case, however,
your brake system is normally
operable.
The ABS warning light will stay ON for approximately 3 seconds
after the ignition switch is ON.
Then, the ABS will perform self-
diagnosis, and if everything is
normal, the light will go OFF. If
the light stays ON, your vehicle
may have a problem with the
ABS. Immediately contact an
authorized EQUUS dealer. When continuously depressing
brakes, while driving on a road
of poor traction, such as an icy
road, the ABS will be continu-
ously active, and the ABS warn-
ing light will illuminate. Pull over
the vehicle in a safe place and
stop the engine.
When restart the engine, and then the ABS warning light goes OFF,
your ABS system is normal.
Otherwise, your vehicle may have
a problem with the ABS.
Immediately contact an author-
ized EQUUS dealer.
Information
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly, and
the ABS warning light may be turned
ON. This happens because of the low
battery voltage. It does not indicate
the ABS malfunction.
• Do not pump your brakes!
• Recharge the battery before drivingthe vehicle.

Check the brake warning light by
turning the ignition switch ON (do not
start the engine). This light illumi-
nates when the parking brake is
depressed with the ignition switch in
the START or ON position.
Before driving, make sure that the
parking brake is fully released and
the brake warning light goes OFF.
When the brake warning light
remains ON even after releasing the
parking brake while engine is run-
ning, there may be a malfunction in
the brake system. Immediate atten-
tion is necessary.
If at all possible, immediately stop
driving. If not, use extreme caution
and continuously drive the vehicle
until you can reach a safe location.
Electronic stability control
(ESC)
The ESC system is to stabilize the
vehicle in cornering maneuvers. The
ESC monitors your steering and driv-
ing. The ESC applies to a brake of an
individual wheel and engage in the
engine management system in order
to stabilize the vehicle.
5-28
Driving your vehicle
OVI055021N
Never drive too fast or quickly
when cornering. The ESC can-
not prevent accidents under
this condition. Excessively high
speed in turning, abrupt driving
maneuvers, and hydroplaning
on a wet surface may result in
serious accidents. Only safe
and attentive driving can pre-
vent accidents, avoiding trac-
tion loss of a vehicle. Even with
the ESC equipment of your
vehicle, always follow all the
driving precautions, including
driving at a safe speed.
WARNING
WKH-002

The ESC system is an electronic
system to help the driver maintain
vehicle control in adverse conditions.
It is not a substitute for safe driving
practices. Various factors, including
speed, road conditions and driver's
steering maneuver, affect the ESC
performance in preventing a loss of
control. It is still driver's responsibility
to drive and corner at a proper speed
and to keep a safe distance. When
depressing the brake under condi-
tions, which may lock the wheels,
you may hear a snapping sound and
feel like that from the brake pedal.
This is normal and indicates your
ESC actively operates.
Information
A clicking sound may be heard from
the engine compartment, when the
engine is started and the vehicle
begins to move. This is normal, indi-
cating that the ESC actively operates.
ESC operation
ESC ON condition
When the Engine Start/Stop button
is turned ON, the ESC and the ESC
OFF indicator lights illuminate for

WARNING

Hill-start assist control (HAC)
A vehicle has the tendency to slide
backwards on a steep slope, when the
driver begins to accelerate after a
stop. The HAC prevents the vehicle
from sliding backwards by automati-
cally operating the brake systems for
about 2 seconds. The brake systems
are automatically released, when the
accelerator pedal is depressed or after
about 2 seconds.
Information
• The HAC does not operate when theshift lever is in P(Park) or
N(Neutral).
• The HAC activates, even when the ESC is OFF. However, it does not
activate, when the ESC malfunc-
tions.
Good braking practices
Make sure the parking brake isreleased and that the parking
brake indicator goes OFF before
driving.
Driving through water may get the brakes wet. The brakes may also
get wet after washing the vehicle.
Wet brakes can be dangerous!
Your vehicle may not quickly stop,
when the brakes are wet. Wet
brakes may cause the vehicle to
slide to one side.
To dry the brake, lightly depress
the brake pedal until the braking
operation returns to normal, taking
care to keep the vehicle under con-
trol at all times. When the braking
operation does not return to nor-
mal, immediately and safely stop
the vehicle and call an authorized
EQUUS dealer for assistance.i
5-32
Driving your vehicle
The HAC is activated only for
about 2 seconds, so always
depress the accelerator pedal
to begin driving upwards after a
stop.
WARNING
Whenever parking or leaving the vehicle, always securely
set the parking brake and
locate the vehicle's shift lever
in P(Park). A vehicle, of which
the shift lever is not in P(Park)
with the parking brake set ON,
is at risk of inadvertently mov-
ing and injuring you or others.
All vehicles should always set the parking brake, when park-
ing, to avoid inadvertent
movement, which may injure
occupants or pedestrians.
