✽NOTICE
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly and
the ABS warning light may turn on
at the same time. This happens
because of low battery voltage. It
does not mean your ABS has mal-
functioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
Electronic Stability Control
(ESC) (If equipped)
The Electronic Stability Control
(ESC) system is designed to stabi-
lize the vehicle during cornering
maneuvers. ESC checks where you
are steering and where the vehicle is
actually going. ESC applies the
brakes on individual wheels and
intervenes with the engine manage-
ment system to stabilize the vehicle.
CAUTION
• When you drive on a road hav-
ing poor traction, such as an
icy road, and have operated
your brakes continuously, the
ABS will be active continuous-
ly and the ABS warning light
may illuminate. Pull your vehi-
cle over to a safe place and
stop the engine.
• Restart the engine. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a
problem with the ABS.
Contact an authorized
HYUNDAI dealer as soon as
possible.

ESC operation
ESC ON condition
• When the ignition is turned
ON, ESC and ESC OFF
indicator lights illuminate
for approximately 3 sec-
onds, then ESC is turned
on.
• Press the ESC OFF but-
ton for at least half a sec-
ond after turning the igni-
tion ON to turn ESC off.
(ESC OFF indicator will
illuminate). To turn the
ESC on, press the ESC
OFF button (ESC OFF
indicator light will go off).
• When starting the engine,
you may hear a slight tick-
ing sound. This is the ESC
performing an automatic
system self-check and
does not indicate a prob-
lem.When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks.
• When the Electronic
Stability Control is operat-
ing properly, you can feel a
slight pulsation in the vehi-
cle. This is only the effect
of brake control and indi-
cates nothing unusual.
• When moving out of the
mud or slippery road, the
engine rpm (revolution per
minute) may not be
increased even if you
press the accelerator
pedal deeply. This is to
maintain the stability and
traction of the vehicle and
does not indicate a prob-
lem.
ESC operation off
ESC OFF state
This car has 2 kinds of ESC
off states.
If the engine stops when
ESC is off, ESC remains off.
Upon restarting the engine,
the ESC will automatically
turn on again.

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 vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
• 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 stop-
lights. Try to adjust your speed to
that of the other traffic so you don't
have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe
distance from other vehicles so
you can avoid unnecessary brak-
ing. This also reduces brake wear.
• Drive at a moderate speed. The
faster you drive, the more fuel your
car uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption.• Don't "ride" the brake 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 con-
sequences.
• Take care of your tires. Keep them
inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
• Be sure that the wheels are
aligned correctly. Improper align-
ment 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.• Keep your car in good condition.
For better fuel economy and
reduced maintenance costs, main-
tain your car in accordance with
the maintenance schedule in sec-
tion 7. If you drive your car in
severe conditions, more frequent
maintenance is required (see sec-
tion 7 for details).
• Keep your car 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 car. This extra
weight can result in increased fuel
consumption and also contribute to
corrosion.
• Travel lightly. Don't carry unneces-
sary weight in your car. 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.

TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or alter-
nate tires or wheels on the vehicle
that prevent the TPMS from function-
ing properly. Always check the TPMS
malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replace-
ment or alternate tires and wheels
allow the TPMS to continue to func-
tion properly.
✽ ✽
NOTICE
If any of the below happens, we rec-
ommend that the system be checked
by an authorized HYUNDAI dealer.
1.The low tire pressure telltale/
TPMS malfunction indicator does
not illuminate for 3 seconds when
the ignition switch is turned to the
ON or engine is running.
2. The TPMS malfunction indicator remains illuminated after blinking
for approximately 1 minute.
3. The Low tire pressure position telltale remains illuminated.

When the tire pressure monitoring
system warning indicators are illumi-
nated and warning message dis-
played on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The low tire
pressure position telltale light will
indicate which tire is significantly
under-inflated by illuminating the cor-
responding position light. If either telltale illuminates, immedi-
ately reduce your speed, avoid hard
cornering 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 a
spare tire.
If you drive the vehicle for about 10
minutes at speeds above 25 km/h
after replacing the low pressure tire
with the spare tire, the below will
happen:
The TPMS malfunction indicator
may blink for approximately 1
minute and then remain continu-
ously illuminated because the
TPMS sensor is not mounted on
the spare wheel.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed at the frequencies indicated
to help ensure safe, dependable
operation of your vehicle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in coolant
reservoir.
• Check the windshield washer fluid
level.
• Look for low or under-inflated tires.
While operating your vehicle:
• Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
• 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 automatic transmission P
(Park) function.
• Check parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).

FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.This vehicle has 4 fuse panels, one
located in the driver’s side panel bol-
ster, another is in the front passen-
ger’s side panel bolster, the others
are in the engine compartment.
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.
If the electrical system does not
work, first check the driver’s side
fuse panel.
Before replacing a blown fuse, dis-
connect the negative battery cable.
Always replace a blown fuse with
one of the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and we
recommend that you consult an
authorized HYUNDAI dealer.Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and fusible link for higher
amperage ratings.
✽NOTICE
The actual fuse/relay panel label
may differ from equipped items.
WARNING - Fuse
replacement
• Never replace a fuse with any-
thing but another fuse of the
same rating.
• A higher capacity fuse could
cause damage and possibly a
fire.
• Never 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
a possible fire.
CAUTION
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.

4.Check the removed fuse; replace it
if it is blown.
Spare fuses are provided in the
passenger compartment panel
fuse panel (or in the engine com-
partment fuse panel).
5.Push in a new fuse of the same rat-
ing, and make sure it fits tightly in
the clips.
If it fits loosely, we recommend that
you consult an authorized HYUNDAI
dealer.
If you do not have a spare, 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 headlights 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.
Fuse switch
Always, put the fuse switch at the ON
position.
If you move the switch to the OFF
position, some items such as audio
and digital clock must be reset and
the smart key may not work properly.
OVI073102
CAUTION
• Always place the fuse switch
in the ON position while driv-
ing the vehicle.
• Do not move the transporta-
tion fuse switch repeatedly.
The fuse switch may be worn
out.
