Engine temperature gauge
This gauge shows the temperature of the
engine coolant when the ignition switch
is ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “If the engine overheats” in section 6.
CAUTION
If the gauge pointer moves beyondthe normal range area toward the“H” position, it indicates overheat-ing that may damage the engine.
CAUTION
Do not operate the engine within the tachometer's RED ZONE.
This may cause severe engine dam-age.WARNING
Never remove the radiator cap
when the engine is hot. The engine
coolant is under pressure and
could cause severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.

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
ignition switch to the ON position, the
Tire Pressure Monitoring System is not
working properly. If this occurs, have your
vehicle checked by an authorized
HYUNDAI dealer as soon as possible.
This warning light will also illuminate if
one or more of your tires is significantly
under-inflated. You should stop and
check your tires as soon as possible. If
the warning light illuminates while driv-
ing, reduce vehicle speed immediately
and stop the vehicle. Avoid hard braking
and overcorrecting at the steering wheel.
Inflate the tires to the proper pressure as
indicated on the vehicle’s tire information
placard.
The TPMS is not a replacement for nor-
mal tire maintenance. Tire inflation
should be checked on a regular basis.
Refer to the TPMS instructions and warn-
ings in section 5.
Engine coolant
temperature warning light
The warning light illuminates if the tem-
perature of the engine coolant is above
248±5.4°F (120±3°C).
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “Overheating” in section 6.
✽ ✽ NOTICE
If the engine coolant temperature warn-
ing light illuminates, it indicates over-
heating that may damage the engine.
Electronic power steering
(EPS) system warning light
This indicator light comes on after the
ignition key is turned to the ON position
and then it will go out after the engine is
started.
This light also comes on when the EPS
has some troubles. If it comes on while
driving, have your vehicle inspected by
an authorized HYUNDAI dealer.

Operation Tips
To keep dust or unpleasant fumes from
entering the car through the ventilation
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 irritation
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.Air conditioning
All HYUNDAI Air Conditioning Systems
are filled with environmentally friendly
R-134a refrigerant which does not dam-
age 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, set the mode control to
the MAX A/C 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 run
with the windows closed.

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 judgment. Driving
while under the influence of drugs
is as dangerous or more dangerous
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.
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.

Driving your vehicle
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, 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.

Driving your vehicle
Good driving practices
Never move the gear shift lever from P(Park) or N (Neutral) to any other posi-
tion with the accelerator pedal
depressed.
Never move the gear shift lever into P (Park) 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
car 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.
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the accelera-
tor pedal.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.

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.
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
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.
When descending a long or steep hill, 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 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 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.

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.

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 gal-
lon (liter) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing 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 pedal or clutch
pedal. This can increase fuel consump-
tion and also increase wear on these
components. 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 conse-
quences.
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.
