Driving your vehicle
Electronic stability program (ESP)
The Electronic Stability Program (ESP)
system is designed to stabilize the
vehicle during cornering maneuvers.
ESP checks where you are steering and
where the vehicle is actually going. ESP
applies the brakes at individual wheels
and intervenes in the engine
management system to stabilize the
vehicle.The Electronic Stability Program (ESP)
system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESP will be effective in
preventing a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESP is active.
✽NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Program System is functioning proper-
ly.
WARNING
Never drive too fast according to
the road conditions or too quickly
when cornering. Electronic stability
program (ESP) will not prevent acci-
dents. Excessive speed in turns,
abrupt maneuvers and hydroplan-
ing on wet surfaces can still result
in serious accidents. Only a safe
and attentive driver can prevent
accidents by avoiding maneuvers
that cause the vehicle to lose trac-
tion. Even with ESP installed,
always follow all the normal precau-
tions for driving - including driving
at safe speeds for the conditions.

ESP operation
ESP ON condition
• When the engine start/stop
button is turned ON, ESP and
ESP OFF indicator lights illu-
minate for approximately 3
seconds, then ESP is turned
on.
• Press the ESP OFF button for
at least half a second after
turning the engine start/stop
button ON to turn ESP off.
(ESP OFF indicator will illumi-
nate). To turn the ESP on,
press the ESP OFF button
(ESP OFF indicator light will
go off).
• When starting the engine,
you may hear a slight ticking
sound. This is the ESP per-
forming an automatic system
self-check and does not indi-
cate a problem.When operating
When the ESP is in operation,
ESP indicator light blinks.
• When the Electronic Stability
Program is operating proper-
ly, you can feel a slight pulsa-
tion in the vehicle. This is only
the effect of brake control and
indicates nothing unusual.
• When moving out of the mud
or slippery road, the engine
rpm (revolution per minute)
may not be increased even if
you press the accelerator
pedal deeply. This is to main-
tain the stability and traction
of the vehicle and does not
indicate a problem.
ESP operation off
ESP OFF state
• To cancel ESP operation,
press the ESP OFF button for
more than 0.5 second. (ESP
OFF indicator light illumi-
nates).
• If the engine stops when ESP
is off, ESP remains off. Upon
restarting the engine, the
ESP will be automatically
turned on again.
Indicator light

Driving your vehicle
• Don't coast down hills with the vehicle
out of gear. This is extremely haz-
ardous. Keep the car in gear at all
times, use the brakes to slow down,
then shift to a lower gear so that
engine braking will help you maintain a
safe speed.
• Don't "ride" the brake pedal. Resting
your foot on the brake pedal while driv-
ing can be dangerous because it can
result in the brakes overheating and
losing their effectiveness. It also
increases the wear of the brake com-
ponents.
• If a tire goes flat while you are driving,
apply the brakes gently and keep the
car pointed straight ahead while you
slow down. When you are moving
slowly enough for it to be safe to do so,
pull off the road and stop in a safe
place.• If your vehicle is equipped with an
automatic transmission, don't let your
car creep forward. To avoid creeping
forward, keep your foot firmly on the
brake pedal when the car is stopped.
• Be caution when parking on a hill.
Firmly engage the parking brake and
place the shift lever in P. If your vehicle
is facing downhill, turn the front wheels
into the curb to help keep the vehicle
from rolling. If your vehicle is facing
uphill, turn the front wheels away from
the curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to keep
the vehicle from rolling, block the
wheels.• Under some conditions your parking
brake can freeze in the engaged posi-
tion. This is most likely to happen when
there is an accumulation of snow or ice
around or near the rear brakes or if the
brakes are wet. If there is a risk that the
parking brake may freeze, apply it only
temporarily while you put the shift lever
in P and block the rear wheels so the
car cannot roll. Then release the park-
ing brake.
• Do not hold the vehicle on the upgrade
with the accelerator pedal. This can
cause the transmission to overheat.
Always use the brake pedal or parking
brake.

To control the vehicle height
Push the vehicle height control button to
select the HIGH mode that makes the
vehicle height be higher than the NOR-
MAL mode and the indicator light on the
vehicle height control button will illumi-
nate. It is useful in a rough road.
✽NOTICE
When you drive over 70km/h, you can
not select the HIGH mode. If the vehicle
speed exceeds 70km/h while driving in
the HIGH mode, the NORMAL mode
will be selected automatically.
Push the vehicle height control button
again to select the NORMAL mode that
makes the vehicle height lower than the
HIGH mode. The indicator light in the
vehicle height control button will go off.
✽NOTICE
•When the vehicle stops with the shift
lever in D(Drive) or R(Reverse), you
can not change the vehicle height.
•If the vehicle speed exceeds 120km/h
while driving in NORMAL mode, the
LOW mode that is lower than NOR-
MAL mode is selected automatically.
LOW mode can not be selected manu-
ally.
•Do not operate ECS when the air filter
of the compressor in the lower part of
the vehicle sinks under the water.
Indraft of water into the compressor
may happen, and ECS may not oper-
ate normally.
•Make sure there are no objects under
the vehicle before changing the vehicle
height.
•A click sound may be heard while
operating ECS, but these conditions
are normal and indicate that ECS is
functioning properly.
•Depending on the outside tempera-
ture the vehicle height may be differ-
ent.
•Do not press the engine start/stop but-
ton to the other position while operat-
ing ECS. This could cause damage to
