WARNING - Low tire pres-sure
Significantly low tire pressure
makes the vehicle unstable and can
contribute to loss of vehicle control
and increased braking distances.
Continued driving on low pressure
tires will cause the tires to overheat
and fail.

Low tire pressure telltale
The low tire pressure telltale comes on
for 3 seconds after the ignition switch is
turned to the ON position.
If the warning light does not come on, or
continuously remains on after coming on
for about 3 seconds when you turned the

Driving your vehicle
If the parking brake does not release or
does not release all the way, have the
system checked by an authorized
HYUNDAI dealer.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 igni-
tion 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 the
engine is running, there may be a mal-
function in the brake system. Immediate
attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution while operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop.Anti-lock brake system (ABS)

WARNING
To prevent unintentional move-ment when stopped and leaving
the vehicle, do not use the shift
lever in place of the parking
brake. Set the parking brake AND
make sure the shift lever is
securely positioned in P (Park).
Never allow anyone who is unfa- miliar 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 inadver-
tent movement of the vehicle
which can injure occupants or
pedestrians.
WARNING
ABS (or ESC) will not prevent acci-
dents due to improper or danger-
ous driving maneuvers. Even
though vehicle control is improved
during emergency braking, always
maintain a safe distance between
you and objects ahead. Vehicle
speeds should always be reduced
during extreme road conditions.
The braking distance for vehicles
equipped with an anti-lock braking
system (or Electronic Stability
Control System) may be longer
than for those without it in the fol-
lowing road conditions.
During these conditions the vehicle
should be driven at reduced
speeds:
Rough, gravel or snow-coveredroads.
With tire chains installed. (Continued)

Driving your vehicle
Good braking practices
Check to be sure the parking brake isnot engaged and that the parking brake
indicator light is out before driving
away.
Driving through water may get the brakes wet. They can also get wet when
the vehicle is washed. Wet brakes can
be dangerous! Your vehicle will not stop
as quickly if the brakes are wet. Wet
brakes may cause the vehicle to pull to
one side. To dry the brakes, apply the brakes
lightly until the braking action returns to
normal, taking care to keep the vehicle
under control at all times. If the braking
action does not return to normal, stop
as soon as it is safe to do so and call an
authorized HYUNDAI dealer for assis-
tance.
Don't coast down hills with the vehicle out of gear. This is extremely haz-
ardous. Keep the vehicle 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 the
brakes might overheat and lose their
effectiveness. It also increases the wear
of the brake components.
If a tire goes flat while you are driving, apply the brakes gently and keep the
vehicle pointed straight ahead while you
slow down. When you are moving slow-
ly 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 auto- matic transaxle, don't let your vehicle
creep forward. To avoid creeping for-
ward, keep your foot firmly on the brake
pedal when the vehicle is stopped. Be cautious when parking on a hill.
Firmly engage the parking brake and
place the shift lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle). 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 (automatic transaxle) or in first or
reverse gear (manual transaxle) and
block the rear wheels so the vehicle
cannot roll. Then release the parking
brake.
Do not hold the vehicle on the upgrade with the accelerator pedal. This can
cause the transaxle to overheat.
Always use the brake pedal or parking
brake.
WARNING
Whenever you leave or park yourvehicle, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the P (Park) position. If the
parking brake is not fully
engaged, the vehicle may move
inadvertently and injure yourself
and others.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants or
pedestrians.
