Disc brakes wear indicator
Your vehicle has disc brakes.
When your brake pads are worn and new
pads are required, you will hear a high-
pitched warning sound from your front
brakes or rear brakes (if equipped). You
may hear this sound come and go or it
may occur whenever you depress the
brake pedal.
Please remember that some driving con-
ditions or climates may cause a brake
squeal when you first apply (or lightly
apply) the brakes. This is normal and
does not indicate a problem with your
brakes.
Rear drum brakes (if equipped)
Your rear drum brakes do not have wear
indicators.Therefore, have the rear brake
linings inspected if you hear a rear brake
rubbing noise. Also have your rear
brakes inspected each time you change
or rotate your tires and when you have
the front brakes replaced.
WARNING- Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking
performance, which could lead to a
serious accident.
CAUTION
To avoid costly brake repairs, donot continue to drive with wornbrake pads.
Always replace brake pads as complete front or rear axle sets.

519
Driving your vehicle
Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will be illuminated
when the parking brake is applied with
the ignition switch in the START or ON
position.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on
after the parking brake is released, there
may be a malfunction in the brake sys-
tem. Immediate attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution while operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop.
Anti-lock brake system (ABS)
(if equipped)

W-75
WARNING
ABS (ESC) will not prevent acci-
dents due to improper or danger-
ous driving maneuvers. Even
though vehicle control is improved
during emergency braking, always
maintain a safe distance between
you and objects ahead. Vehicle
speeds should always be reduced
during extreme road conditions.
The braking distance for cars
equipped with an anti-lock braking
system (Electronic Stability Control
System) may be longer than for
those without it in the following
road conditions.
During these conditions the vehicle
should be driven at reduced
speeds:
Rough, gravel or snow-coveredroads.
With tire chains installed.
On roads where the road surface is pitted or has different surface
height.
(Continued)
WARNING
To prevent unintentional move-ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parking
brake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transaxle
equipped vehicles and in P (Park)
for automatic transaxle equipped
vehicles.
Never allow a person who is unfa- miliar with the vehicle or children
to touch the parking brake. If the
parking brake is released unin-
tentionally, serious injury may
occur.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the car which
can injure occupants or pedestri-
ans.

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 that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. 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, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-
tion. 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 car in good condition. For better fuel economy and reduced
maintenance costs, maintain your car
in accordance with the maintenance
schedule in Section 7. If you drive your
car in severe conditions, more frequent
maintenance is required (see Section
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 con-
sumption and also contribute to corro-
sion.
Travel lightly. Don't carry unnecessary 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.
Remember, your vehicle does not require extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too
high a gear resulting in the engine
bucking. If this happens, shift to a lower
gear. Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speeds.
ECONOMICAL OPERATION

Driving your vehicle
If you are considering towing with your
car, you should first check with your
state’s Department of Motor Vehicles to
determine their legal requirements.
Since laws vary from state to state the
requirements for towing trailers, cars, or
other types of vehicles or apparatus may
differ. Ask an authorized Hyundai dealer
for further details before towing.Your vehicle can tow a trailer. To identify
what the vehicle trailering capacity is for
your vehicle, you should read the infor-
mation in “Weight of the trailer” that
appears later in this section.
Remember that trailering is different than
just driving your vehicle by itself.
Trailering means changes in handling,
durability, and fuel economy. Successful,
safe trailering requires correct equip-
ment, and it has to be used properly.This section contains many time-tested,
important trailering tips and safety rules.
Many of these are important for your
safety and that of your passengers.
Please read this section carefully before
you pull a trailer.
Load-pulling components such as the
engine, transaxle, wheel assemblies, and
tires are forced to work harder against
the load of the added weight. The engine
is required to operate at relatively higher
speeds and under greater loads. This
additional burden generates extra heat.
The trailer also adds considerably to
wind resistance, increasing the pulling
requirements.
TRAILER TOWING
WARNING- Towing a trail-
er
If you don't use the correct equip-
ment and drive improperly, you can
lose control when you pull a trailer.
For example, if the trailer is too
heavy, the brakes may not work
well - or even at all. You and your
passengers could be seriously or
fatally injured. Pull a trailer only if
you have followed all the steps in
this section.
WARNING- Weight limits
Before towing, make sure the total
trailer weight, gross combination
weight, gross vehicle weight, gross
axle weight and trailer tongue load
are all within the limits.
CAUTION
Pulling a trailer improperly can
damage your vehicle and result incostly repairs not covered by yourwarranty. To pull a trailer correctly,follow the advice in this section.

551
Driving your vehilcle
WARNING - Loose cargo
Items you carry inside your
vehicle can strike and injure
occupants in a sudden stop or
turn, or in a crash.
Put items in the cargo area of your vehicle. Try to spread the
weight evenly.
Never stack items, like suit- cases, inside the vehicle
above the tops of the seats.
Do not leave an unsecured child restraint in your vehicle.
When you carry something inside the vehicle, secure it.
Do not drive with a seat folded down unless necessary.CAUTION
Overloading your vehicle may cause damage. Repairs wouldnot be covered by your war-ranty. Do not overload yourvehicle.
Using heavier suspension components to get addeddurability might not changeyour weight ratings. Ask yourdealer to help you load yourvehicle the right way.

ROAD WARNING
Hazard warning flasher
The hazard warning flasher serves as a
warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle. It should be used whenever emergency
repairs are being made or when the vehi-
cle is stopped near the edge of a road-
way.
Depress the flasher switch with the igni-
tion switch in any position. The flasher
switch is located in the center console
switch panel. All turn signal lights will
flash simultaneously.
• The hazard warning flasher operates
whether your vehicle is running or not.
The turn signals do not work when the hazard flasher is on.
Care must be taken when using the hazard warning flasher while the vehi-
cle is being towed.
If the engine stalls at a crossroad
and crossing
If the engine stalls at a crossroad or
crossing, set the shift lever in the N
(Neutral) position and then push the vehi-
cle to a safe place.
If you have a flat tire while driving
If a tire goes flat while you are driving:
1. Take your foot off the accelerator pedaland let the car slow down while driving
straight ahead. Do not apply the brakes
immediately or attempt to pull off the
road as this may cause a loss of con-
trol. When the car has slowed to such
a speed that it is safe to do so, brake
carefully and pull off the road. Drive off
the road as far as possible and park on
firm, level ground. If you are on a divid-
ed highway, do not park in the median
area between the two traffic lanes.
2. When the car is stopped, turn on your emergency hazard flashers, set the
parking brake and put the transaxle in
P (automatic transaxle) or reverse
(manual transaxle).
3. Have all passengers get out of the car. Be sure they all get out on the side of
the car that is away from traffic.

EMERGENCY STARTING
Jump starting
Jump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting proce-
dures. If in doubt, we strongly recom-
mend that you have a competent techni-
cian or towing service jump start your
vehicle.
Jump starting procedure
1. Make sure the booster battery is 12-
volt and that its negative terminal is
grounded.
2. If the booster battery is in another vehicle, do not allow the vehicles to
touch.
3. Turn off all unnecessary electrical loads.
4. Connect the jumper cables in the exact sequence shown in the illustration.
First connect one end of a jumper
cable to the positive terminal of the
discharged battery (1), then connect
the other end to the positive terminal
on the booster battery (2). Proceed to
connect one end of the other jumper
cable to the negative terminal of the
booster battery (3), then the other end
to a solid, stationary, metallic point (for
example, the engine lifting bracket)
away from the battery (4). Do not con-
nect it to or near any part that moves
when the engine is cranked.
Do not allow the jumper cables to con-
tact anything except the correct battery
terminals or the correct ground. Do not
lean over the battery when making
connections.CAUTION
Use only a 12-volt jumper system. You can damage a 12-volt startingmotor, ignition system, and otherelectrical parts beyond repair byuse of a 24-volt power supply (eithertwo 12-volt batteries in series or a 24-volt motor generator set).
WARNING- Battery
• Keep all flames or sparks away from the battery. The battery pro-
duces hydrogen gas which may
explode if exposed to flame or
sparks.
Do not attempt to jump start the vehicle if the discharged battery
is frozen or if the electrolyte level
is low; the battery may rupture or
explode.
WARNING- Battery
Never attempt to check the elec-
trolyte level of the battery as this
may cause the battery to rupture or
explode causing serious injury.

Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is provided by a
separate telltale, which displays the
symbol "TPMS" when illuminated.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent the
TPMS from functioning properly.
Always check the TPMS malfunction
indicator after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the TPMS
to continue to function properly. Low tire pressure tell-
tale
When the tire pressure monitoring
system warning telltale is illuminat-
ed, one or more of your tires is sig-
nificantly under-inflated.
Immediately reduce your speed,
avoid hard cornering and anticipate
increased stopping distances. You
should stop and check your tires as
soon as possible. Inflate the tires to
the proper pressure as indicated on
the vehicle’s placard or tire inflation
pressure label located on the driver’s
side center 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 compact spare tire. Because the
compact spare tire is not equipped
with a tire pressure sensor, the
TPMS malfunction indicator may go
on and the Low Tire Pressure telltale
still turn on after restarting and about
20 minutes of continuous driving
before you have the low-pressure tire
repaired and replaced on the vehicle.
CAUTION
In winter or cold weather, the low tire pressure telltale may beilluminated if the tire pressurewas adjusted to the recom-mended tire inflation pressurein warm weather. It does notmean your TPMS is malfunction-ing because the decreased tem-perature leads to a proportionallowering of tire pressure.
When you drive your vehiclefrom a warm area to a cold areaor from a cold area to a warmarea, or the outside temperatureis greatly higher or lower, youshould check the tire inflationpressure and adjust the tires tothe recommended tire inflationpressure.
