WARNING- Automatic
transmis-
sion
• Always check the surrounding
areas near your vehicle for
people, especially children,
before shifting a car into D
(Drive) or R (Reverse).
• Before leaving the driver’s
seat, always make sure the
shift lever is in the P (Park)
position; then set the parking
brake fully and shut the
engine off. Unexpected and
sudden vehicle movement
can occur if these precautions
are not followed in the order
identified.
• Do not use the engine brake
(shifting from a high gear to
lower gear) rapidly on slip-
pery roads. The vehicle may
slip causing an accident.
CAUTION
• To avoid damage to your
transmission, do not acceler-
ate the engine in R (Reverse)
or any forward gear position
with the brakes on.
• When stopped on an incline,
do not hold the vehicle sta-
tionary with engine power.
Use the service brake or the
parking brake.
• Do not shift from N (Neutral)
or P (Park) into D (Drive), or R
(Reverse) when the engine is
above idle speed.

Driving your vehicle
Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
In the event that the power-assisted
brakes lose power because of a
stalled engine or some other reason,
you can still stop your vehicle by
applying greater force to the brake
pedal than you normally would. The
stopping distance, however, will be
longer.
When the engine is not running, the
reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.
BRAKE SYSTEM
(Continued)
To dry the brakes, apply them
lightly while maintaining a
safe forward speed until brake
performance returns to nor-
mal.
• Always, confirm the position
of the brake and accelerator
pedal before driving. If you
don't check the position of the
accelerator and brake pedal
before driving, you may
depress the accelerator
instead of the brake pedal. It
may cause a serious accident.WARNING- Brakes
• Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
• When descending a long or
steep hill, shift to a lower gear
and avoid continuous applica-
tion of the brakes. Continuous
brake application will cause
the brakes to overheat and
could result in a temporary
loss of braking performance.
• Wet brakes may impair the
vehicle’s ability to safely slow
down; the vehicle may also
pull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water.
(Continued)

525
Driving your vehicle
Check the brake warning light by
turning the ignition switch ON (do not
start the engine). This light will be
illuminated when the parking brake is
applied with the ignition switch in the
START or ON position.
Before driving, be sure the parking
brake is fully released and the brake
warning light is off.
If the brake warning light remains on
after the parking brake is released
while engine is running, there may
be a malfunction in the brake sys-
tem. Immediate attention is neces-
sary.If at all possible, cease driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location or repair
shop.
WARNING
• To prevent unintentional
movement when stopped and
leaving the vehicle, do not use
the gearshift lever in place of
the parking brake. Set the
parking brake AND make sure
the gearshift lever is securely
positioned in P (Park) for
automatic transmission
equipped vehicles.
• Never allow anyone who is
unfamiliar with the vehicle to
touch the parking brake. If the
parking brake is released
unintentionally, serious injury
may occur.
• All vehicles should always
have the parking brake fully
engaged when parking to
avoid inadvertent movement
of the vehicle which can injure
occupants or pedestrians.

✽NOTICE
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly and
the ABS warning light may turn on
at the same time. This happens
because of low battery voltage. It
does not mean your ABS has mal-
functioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
Electronic Stability Control
(ESC) (If equipped)
The Electronic Stability Control
(ESC) system is designed to stabi-
lize the vehicle during cornering
maneuvers. ESC checks where you
are steering and where the vehicle is
actually going. ESC applies the
brakes on individual wheels and
intervenes with the engine manage-
ment system to stabilize the vehicle.
CAUTION
• When you drive on a road hav-
ing poor traction, such as an
icy road, and have operated
your brakes continuously, the
ABS will be active continuous-
ly and the ABS warning light
may illuminate. Pull your vehi-
cle over to a safe place and
stop the engine.
• Restart the engine. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a
problem with the ABS.
Contact an authorized
HYUNDAI dealer as soon as
possible.
