Operation Tips
To keep dust or unpleasant fumes fromentering the vehicle through the venti-
lation system, temporarily set the air
intake control to the recirculated air
position. Be sure to return the control
to the fresh air position when the irrita-
tion has passed to keep fresh air in the
vehicle. This will help keep the driver
alert and comfortable.
Air for the heating/cooling system is drawn in through the grilles just ahead
of the windshield. Care should be
taken that these are not blocked by
leaves, snow, ice or other obstructions.
To prevent interior fog on the wind- shield, set the air intake control to the
fresh air position and fan speed to the
desired position, turn on the air condi-
tioning system, and adjust the temper-
ature control to desired temperature.D230503AFD
Air conditioning (if equipped)
All HYUNDAI Air Conditioning Systems
are filled with environmentally friendly
R-134a refrigerant which does not dam-
age to the ozone layer.
1. Start the engine. Push the air condi- tioning button.
2. Set the mode to the position.
3. Set the air intake control to the outside air or recirculated air position.
4. Adjust the fan speed control and tem- perature control to maintain maximum
comfort.
When maximum cooling is desired, set the temperature control to the extreme
left position then set the fan speed
control to the highest speed.
✽ ✽ NOTICE
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.
• When opening the windows in humid weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
air conditioning should only be used
with the windows closed.

WARNING
When you intend to park or stop the
vehicle with the engine on, be care-
ful not to depress the accelerator
pedal for a long period of time. It
may overheat the engine or exhaust
system and cause fire.
WARNING- Driving under
the influence of alcohol or
drugs
Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgement.
Driving while under the influence of
drugs is as dangerous or more dan-
gerous than driving drunk.
You are much more likely to have a
serious accident if you drink or
take drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.

Good driving practices
Never take the vehicle out of gear andcoast down a hill. This is extremely
hazardous. Always leave the vehicle in
gear.
Don't "ride" the brakes. This can cause them to overheat and malfunction.
Instead, when you are driving down a
long hill, slow down and shift to a lower
gear. When you do this, engine braking
will help slow down the vehicle.
Slow down before shifting to a lower gear. This will help avoid over-revving
the engine, which can cause damage.
Slow down when you encounter cross winds. This gives you much better con-
trol of your vehicle.
Be sure the vehicle is completely stopped before you attempt to shift into
reverse. The transaxle can be dam-
aged if you do not. To shift into reverse,
depress the clutch, move the shift lever
to neutral, wait three seconds, then
shift to the reverse position.
Exercise extreme caution when driving on a slippery surface. Be especially
careful when braking, accelerating or
shifting gears. On a slippery surface,
an abrupt change in vehicle speed can
cause the drive wheels to lose traction
and the vehicle to go out of control.
WARNING
Always buckle-up! In a collision,an unbelted occupant is signifi-
cantly more likely to be seriously
injured or killed than a properly
belted occupant.
Avoid high speeds when corner- ing or turning.
Do not make quick steering wheel movements, such as sharp
lane changes or fast, sharp turns.
The risk of rollover is greatly increased if you lose control of
your vehicle at highway speeds.
Loss of control often occurs if two or more wheels drop off the
roadway and the driver over-
steers to reenter the roadway.
In the event your vehicle leaves the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
Never exceed posted speed lim- its.

Shift-lock override
If the shift lever cannot be moved from
the P (Park) or N (Neutral) position into R
(Reverse) position with the brake pedal
depressed, continue depressing the
brake, then do the following:
1. Carefully remove the cap (1) covering
the shift-lock override access hole.
2. Insert a screwdriver (or key) into the access hole and press down on the
screwdriver (or key).
3. Move the shift lever.
4. Have your vehicle inspected by an authorized HYUNDAI dealer immedi-
ately.
E060103AUN
Ignition key interlock system
(if equipped)
The ignition key cannot be removed
unless the shift lever is in the P (Park)
position. If the ignition switch is in any
other position, the key cannot be
removed.
E060200AFD
Good driving practices
Never move the shift lever from P(Park) or N (Neutral) to any other posi-
tion with the accelerator pedal
depressed.
Never move the shift lever into "P" when the vehicle is in motion.
Be sure the vehicle is completely stopped before you attempt to shift into
R (Reverse) or D (Drive).
Never take the vehicle out of gear and coast down a hill. This may be
extremely hazardous. Always leave the
vehicle in gear when moving.
Do not "ride" the brakes. This can cause them to overheat and malfunc-
tion. Instead, when you are driving
down a long hill, slow down and shift to
a lower gear. When you do this, engine
braking will help slow down the vehicle.
Slow down before shifting to a lower gear. Otherwise, the lower gear may
not be engaged.
Always use the parking brake. Do not depend on placing the transaxle in P
(Park) to keep the vehicle from moving.
Exercise extreme caution when driving on a slippery surface. Be especially
careful when braking, accelerating or
shifting gears. On a slippery surface,
an abrupt change in vehicle speed can
cause the drive wheels to lose traction
and the vehicle to go out of control.

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 nor-
mally would. The stopping distance, how-
ever, 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 neces-
sary to maintain steering control on slip-
pery surfaces.
E070101AUN
In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
BRAKE SYSTEM
(Continued)
When descending a long or steephill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may impair the vehi- cle’s ability to sefely 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 fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
WARNING- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.
WARNING - Brakes
Do not drive with your foot rest-ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.

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
assistance.
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 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
vehicle 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 transaxle, don't let your vehi-
cle creep forward. To avoid creeping
forward, keep your foot firmly on the
brake pedal when the vehicle is
stopped.
Use caution 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 gear
selector 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.

Driving your vehicle
Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
miles (kilometers) you can get from a
gallon (liter) of fuel. To operate your vehi-
cle as economically as possible, use the
following driving suggestions to help
save money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-ate 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 the traffic so you don't have to
change speeds unnecessarily. Avoid
heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary braking. This also reduces
brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your vehicle
uses. Driving at a moderate speed,
especially on the highway, is one of the
most effective ways to reduce fuel con-
sumption. Don't "ride" the brake or clutch pedal.
This can increase fuel consumption
and also increase wear on these com-
ponents. In addition, driving with your
foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may
lead to more serious consequences.
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.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire wear and may
also result in other problems as well as
greater fuel consumption. Keep your vehicle in good condition.
For better fuel economy and reduced
maintenance costs, maintain your vehi-
cle in accordance with the mainte-
nance schedule in Section 7. If you
drive your vehicle in severe conditions,
more frequent maintenance is required
(see Section 7 for details).
Keep your vehicle clean. For maximum service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the vehicle. This
extra weight can result in increased
fuel consumption and also contribute
to corrosion.
Travel lightly. Don't carry unnecessary weight in your vehicle. Weight reduces
fuel economy.
Don't let the engine idle longer than necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.

Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, follow
these suggestions:
Drive cautiously and allow extra dis-tance for braking.
Avoid sudden braking or steering.
When braking with non-ABS brakes pump the brake pedal with a light up-
and-down motion until the vehicle is
stopped.
If stalled in snow, mud, or sand, use second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, tire chains, or other non-slip material under the drive
wheels to provide traction when stalled
in ice, snow, or mud.
E110200AEN
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between 1st (First)
and R (Reverse) in vehicles equipped
with a manual transaxle or R (Reverse)
and any forward gear in vehicles
equipped with an automatic transaxle.
Do not race the engine, and spin the
wheels as little as possible. If you are still
stuck after a few tries, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating and possible dam-
age to the transaxle.
SPECIAL DRIVING CONDITIONS
WARNING - Downshifting
Downshifting with an automatic
transaxle, while driving on slippery
surfaces can cause an accident.
The sudden change in tire speed
could cause the tires to skid. Be
careful when downshifting on slip-
pery surfaces.
WARNING - ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
CAUTION
Prolonged rocking may causeengine over-heating, transaxle dam-age or failure, and tire damage.

Tires:
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
✽ ✽
NOTICE
Never exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oil:
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engine
oil.
Drive belt:
A loose or damaged drive belt may result
in overheating of the engine.

WARNING
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
Always check the tires for proper
inflation before driving. For prop-
er tire pressures, refer to section
8, “Tires and wheels”.
Driving on tires with no or insuffi- cient tread is dangerous. Worn-
out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tires
should be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
vehicle. For further information
and tread limits, refer to section
7, “Tires and wheels”.
