Cruise Control operation
➀Cruise indicator
➁Set speed
The Cruise Control system allows
you to drive at speeds above 20 mph
(30 km/h) without depressing the
accelerator pedal.
Information
• During normal cruise control opera-
tion, when the SET switch is activat-
ed or reactivated after applying the
brakes, the cruise control will ener-
gize after approximately 3 seconds.
This delay is normal.
• Before activating the cruise control
function, the system will check to
verify that the brake switch is oper-
ating normally. Depress the brake
pedal at least once after turning ON
the ignition or starting the engine.

Take the following precautions:
If the Cruise Control is left on,
("CRUISE" indicator light in
the instrument cluster is illu-
minated) the Cruise Control
can be activated unintention-
ally. Keep the Cruise Control
system off ("CRUISE" indica-
tor light OFF) when the Cruise
Control is not in use, to avoid
inadvertently setting a speed.
Use the Cruise Control sys-
tem only when traveling on
open highways in good
weather.
Do not use Cruise Control
when towing a trailer.
Do not use the Cruise Control
when it may be unsafe to keep
the vehicle at a constant
speed:
WARNING

5-124
Driving your vehicle
If you believe your brakes may be
wet, apply them lightly while driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increases
as the depth of tire tread decreas-
es, refer to "Tire replacement" in
chapter 7.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Highway driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engine
oil
Driving at higher speeds on the high-
way consumes more fuel and is less
efficient than driving at a slower,
more moderate speed. Maintain a
moderate speed in order to conserve
fuel when driving on the highway.
Be sure to check both the engine
coolant level and the engine oil
before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

The severe weather conditions of
winter quickly wear out tires and
cause other problems. To minimize
winter driving problems, you should
take the following suggestions:
Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause the vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tires
If you mount snow tires on your vehi-
cle, make sure to use radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
The traction provided by snow tires
on dry roads may not be as high as
your vehicle's original equipment
tires. Check with the tire dealer for
maximum speed recommendations.
Information
Do not install studded tires without
first checking local, state and munici-
pal regulations for possible restric-
tions against their use.
Tire chains
Since the sidewalls of radial tires are
thinner than other types of tires, they
may be damaged by mounting some
types of tire chains on them.
Therefore, the use of snow tires is
recommended instead of tire chains.
Do not mount tire chains on vehicles
equipped with aluminum wheels; if
unavoidable use a wire type chain. If
tire chains must be used, use gen-
uine HYUNDAI parts and install the
tire chain after reviewing the instruc-
tions provided with the tire chains.
Damage to your vehicle caused by
improper tire chain use is not cov-
ered by your vehicle manufacturer's
warranty.
i
Snow tires should be equivalent
in size and type to the vehicle’s
standard tires. Otherwise, the
safety and handling of your
vehicle may be adversely affect-
ed.

Driving your vehicle
5. Start the vehicle, apply the brakes,
shift to neutral, release the park-
ing brake and slowly release the
brakes until the trailer chocks
absorb the load.
6. Reapply the brakes and parking
brakes.
7. Move the shift lever to P (Park).
8. Shut off the vehicle and release
the vehicle brakes but leave the
parking brake set.
Driving the vehicle after it has
been parked on a hill
1. With the gear shift lever in P
(Park), apply the brakes and hold
the brake pedal down while per-
forming the following:

and

2. Slowly remove your foot from the
brake pedal.
3. Drive slowly until the trailer is clear
of the chocks.
4. Stop and have someone pick up
and store the chocks.
Maintenance when trailer tow-
ing
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transmission fluid, axle lubri-
cant and cooling system fluid. Brake
condition is another important item to
frequently check. If you’re trailering,
it’s a good idea to review these items
before you start your trip. Don't forget
to also maintain your trailer and
hitch. Follow the maintenance sched-
ule that accompanied your trailer and
check it periodically. Preferably,
inspect the vehicle and trailer at the
start of each day's driving. Inspect
the hitch mounting to make sure the
hitch is properly secured to the vehi-
cle. Inspect the trailer electrical
wiring to make sure brake lights, turn
signal lights, running lights, and haz-
ard lights are working properly.
Do not get out of the vehicle
without the parking brake
firmly set. If you have left the
engine running, the vehicle
can move suddenly. You and
others could be seriously or
fatally injured.
Do not apply the accelerator
pedal to hold the vehicle on
an uphill.
WARNING

What to do in an emergency
If you Have a Flat Tire While
Driving
If a tire goes flat while you are driving:
Take your foot off the accelerator
pedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately or
attempt to pull off the road as this
may cause loss of vehicle control
resulting in an accident. When the
vehicle has slowed to such a speed
that it is safe to do so, brake care-
fully and pull off the road. Drive off
the road as far as possible and park
on firm, level ground. If you are on
a divided highway, do not park in
the median area between the two
traffic lanes.
When the vehicle is stopped, press
the hazard warning flasher button,
move the shift lever into P(Park),
and apply the parking brake, and
place the ignition switch in the
LOCK/OFF position.
Have all passengers get out of the
vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
When changing a flat tire, follow
the instructions provided later in
this chapter.
If the Engine Doesn't Turn
Over or Turns Over Slowly
Be sure the shift lever is in N
(Neutral) or P (Park). The engine
starts only when the shift lever is in
N (Neutral) or P (Park).
Check the battery connections to
be sure they are clean and tight.
Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle. See instructions for
"Jump Starting" provided in this
chapter.
If the Engine Turns Over
Normally but Doesn't Start
Check the fuel level and add fuel if
necessary.
If the engine still does not start, have
your vehicle checked by an author-
ized HYUNDAI dealer.

What to do in an emergency
If any of the below happens, have
the system checked by an author-
ized HYUNDAI dealer.
1. The Low Tire Pressure TPMS
Malfunction Indicator does not
illuminate for 3 seconds when
the ignition switch is placed to
the ON position or engine is
running.
2. The TPMS Malfunction Indicator
remains illuminated after blink-
ing for approximately 1 minute.
3. The Low Tire Pressure LCD dis-
play remains illuminated
Low Tire Pressure
Telltale
Low Tire Pressure LCD
Display with Position Indicator
When the tire pressure monitoring
system warning indicators are illumi-
nated and the warning message is
displayed on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The LCD posi-
tion indicator will indicate which tire
is significantly under-inflated by illu-
minating the corresponding position
light.If any of your tire pressures are indi-
cated as being low, immediately
reduce your speed, avoid hard cor-
nering, and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver’s side cen-
ter pillar outer panel.
If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire Pressure LCD position
indicator will remain on and the
TPMS Malfunction Indicator may
blink for one minute and then remain
illuminated until you have the low
pressure tire repaired and replaced
on the vehicle.
The spare tire is not equipped with
a tire pressure sensor.

Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
Check the coolant level in theengine coolant reservoir.
Check the windshield washer fluid level.
Check for tire for low or under- inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission P (Park) function. Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not
work, first check the driver’s side
fuse panel. Before replacing a blown
fuse, turn the engine and all switches
off, and then disconnect the negative
battery cable. Always replace a
blown fuse with one of the same rat-
ing.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer.Information
Four kinds of fuses are used : blade
type For lower amperage rating, car-
tridge type/Multi fuse/Battery fuse
terminal for higher amperage ratings.
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the sys-
tem.
NOTICE
i
NEVER replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse could
cause damage and possibly
cause a fire.
Do not install a wire or alu-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.

Replacement
1. Turn the engine off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside ofthe fuse panel cover to locate the
suspected fuse location. 5. Pull the suspected fuse straight
out. Use the removal tool provided
in the engine compartment fuses
panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are
provided in the instrument panel
fuse panels (or in the engine com-
partment fuse panel).
7. Push in a new fuse of the same rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorized HYUNDAI dealer. In an emergency, if you do not have
a spare fuse, use a fuse of the same
rating from a circuit you may not
need for operating the vehicle, such
as the cigarette lighter fuse.
If the headlamps or other electrical
components do not work and the
fuses are OK, check the fuse panel
in the engine compartment. If a fuse
is blown, it must be replaced with the
same rating.
