B990C01LZ-GATCurtain AirbagCurtain airbags are located along both sides of
the roof rails above the front and rear doors.
They are designed to help protect the heads of
the front seat occupants and the rear outboard
seat occupants in certain side impact collisions.
The curtain airbags are designed to deploy only
during certain side impact collisions, depending
on the crash severity, angle, speed and impact.
The curtain airbags are not designed to deploy
in all side impact situations, collisions from the
front or rear of the vehicle or in most rollover
situations.

Curtain Airbag
B240C01NF-AATSRS CareThe SRS is virtually maintenance-free and so
there are no parts you can safely service by
yourself. If the SRS "AIRBAG" warning light
does not illuminate, or continuously remains on,
have your vehicle immediately inspected by
your Hyundai dealer.
Any work on the SRS system, such as remov-
ing, installing, repairing, or any work on the
steering wheel must be performed by a qualified
Hyundai technician. Improper handling of the
SRS system may result in serious personal
injury.
WARNING:
o Do not install a child restraint system in
the front passenger seat position.
A child restraint system must never be
placed in the front seat. The infant or
child could be severely injured by an
airbag deployment in case of an acci-
dent.
o Modification to SRS components or wir-
ing, including the addition of any kind of
badges to the pad covers or modifica-
tions to the body structure, can ad-
versely affect SRS performance and lead
to possible injury.
o For cleaning the airbag pad covers, use
only a soft, dry cloth or one which has
been moistened with plain water. Sol-
vents or cleaners could adversely affect
the airbag covers and proper deploy-
ment of the system.
o No objects should be placed over or near
the airbag modules on the steering wheel,
instrument panel, and the front
passenger's panel above the glove box,
because any such object could cause
harm if the vehicle is in a crash severe
enough to cause the airbags to inflate.

1. OdometerThe odometer records the total distance trav-
eled in miles. You will also find the odometer
useful to determine when periodic maintenance
should be performed.NOTE:Federal law forbids alteration of the odom-
eter of any vehicle with the intent to change
the mileage registered on the odometer.
The alteration may void your warranty cov-
erage.Pushing in the TRIP switch behind the left side
of the steering wheel when the ignition switch is
turned "ON" will display two trip odometers in
miles.

CAUTION:
o Shift into "R" and "P" position only when
the vehicle has completely stopped.
o Do not accelerate the engine in reverse
or any of the forward positions with the
brakes applied.
o Always apply the footbrake when shift-
ing from "P" or "N", to "R" or "D"position.
o Do not use the "P" (Park) position in
place of the parking brake. Always set
the parking brake, shift the transaxle
into "P" (Park) position and turn off the
ignition when you leave the vehicle, even
momentarily. Never leave the vehicle
unattended while the engine is running.
o When accelerating from a stop on a
steep hill, the vehicle may have a ten-
dency to roll backwards. Shifting the
shift lever into 2nd gear while in Sport
mode will help prevent the vehicle from
rolling backwards.
o Check the automatic transaxle fluid level
regularly, and add fluid as necessary.
o See the maintenance schedule for the
proper fluid recommendation.
C090H01L-GATNOTE:o For smooth and safe operation, depress
the brake pedal when shifting from "Neu-
tral" position or "Park" position to a
forward or reverse gear.
o The ignition key must be in the "ON"
position and the brake pedal fully de-
pressed in order to move the shift lever
from the "P" (Park) position to any of the
other positions.
o It is always possible to shift from "R",
"N", or "D" position to "P" position. The
vehicle must be fully stopped to avoid
transaxle damage. o To maintain the required levels of ve-
hicle performance and safety, the sys-
tem may not execute certain gearshifts
when the selector lever is operated.
o Before driving away from a stop on a
slippery road, push the selector lever
forward into the +(UP) position. This
causes the transaxle to shift into 2nd
gear which is better for smooth driving
away on a slippery road. Push the selec-
tor lever to the -(DOWN) side to shift
back to 1st gear.
C090J01NF-GATSHIFT LOCK RELEASE (If Installed)If you cannot move the shift lever from the "P"
(Park) position to any other position with the
brake pedal fully depressed and the ignition key
in the "ON" position, remove the cap on the
console and with a thin object such as a flat-
head screwdriver, push the shift lock release
button down. Then, with the brake pedal de-
pressed, move the shift lever to the desired
position, and then the shift lock release button
will automatically return to its original position
after shifting from the "P" (Park) position. Then,
reinstall the cap.
If you need to use the shift lock release, it could
mean your car is developing a problem. Have
the car checked by your Hyundai dealer.

o Be sure that the wheels are aligned cor-
rectly. Improper alignment can result from
hitting curbs or driving too fast over irregular
surfaces. Poor alignment causes faster tire
wear and may also result in other problems
as well as greater fuel consumption.
o Keep your car in good condition. For better
fuel economy and reduced maintenance
costs, maintain your car in accordance with
the maintenance schedule in Section 5. If
you drive your car in severe conditions,
more frequent maintenance is required (see
Section 5 for details).
o Keep your car clean. For maximum service,
your Hyundai should be kept clean and free
of corrosive materials. It is especially impor-
tant that mud, dirt, ice, etc. not be allowed to
accumulate on the underside of the car. This
extra weight can result in increased fuel
consumption and also contribute to corro-
sion.
o Travel lightly. Don't carry unnecessary
weight in your car. Weight reduces fuel
economy.
o Don't let the engine idle longer than neces-
sary. If you are waiting (and not in traffic),
turn off your engine and restart only when
you're ready to go.
DRIVING FOR ECONOMYC140A01A-AATYou can save fuel and get more miles from your
car if you follow these suggestions:
o Drive smoothly. Accelerate at a moderate
rate. Don't make "jack-rabbit" starts or full-
throttle shifts and maintain a steady cruising
speed. Don't race between stoplights. Try to
adjust your speed to that of the other traffic
so you don't have to change speeds unnec-
essarily. Avoid heavy traffic whenever pos-
sible. Always maintain a safe distance from
other vehicles so you can avoid unneces-
sary braking. This also reduces brake wear.
o Drive at a moderate speed. The faster you
drive, the more fuel your car uses. Driving at
a moderate speed, especially on the high-
way, is one of the most effective ways to
reduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This
can increase fuel consumption and also
increase wear on these components. In
addition, driving with your foot resting on the
brake pedal may cause the brakes to over-
heat, which reduces their effectiveness and
may lead to more serious consequences.
o Take care of your tires. Keep them inflated
to the recommended pressure. Incorrect
inflation, either too much or too little, results
in unnecessary tire wear. Check the tire
pressures at least once a month. o Under some conditions your parking brake
can freeze in the engaged position. 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 gear selector lever in "P" (automatic) or
in first or reverse gear (manual transaxle)
and block the rear wheels so the car cannot
roll. Then release the parking brake.
o 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.
