C310B01TG-AATESC ON/OFF ModeWhen the ESC is operating, the ESC indi-
cator in the instrument cluster will blink.
If you turn the system off by pressing the
ESC switch, the ESC-OFF indicator will
come on and stay on. In the ESC-OFF
mode, the stability control will be deacti-
vated. Adjust your driving accordingly. To
turn the system back on, press the switch
again. The ESC-OFF indicator should go
off.NOTE:o The ESC mode will automatically be
turned ON after the engine is turned
off and restarted.
o A click sound may be heard in the
engine compartment when the ve-
hicle begins to move after the engine
is started. These conditions are nor-
mal and indicate that the Electronic
Stability Control System is function-
ing properly. The Electronic Stability Control (ESC) sys-
tem is an electronic system designed to
help the driver maintain vehicle control
under adverse conditions. It is not a substi-
tute for safe driving practices. Factors in-
cluding speed, road conditions and driver
steering input can all affect whether ESC
will be effective in preventing a loss of
control. It is still your responsibility to drive
and corner at reasonable speeds and to
leave a sufficient margin of safety.
!
CAUTION:
Driving with varying tire or wheel sizes
may cause the ESC system to malfunc-
tion. When replacing tires, make sure
they are the same size as your original
tires.
The Electronic Stability Control (ESC) sys-
tem is designed to stabilize the vehicle
during cornering manuevers. ESC checks
where you are steering and where the
vehicle is actually going. ESC applies the
brakes at individual wheels and intervenes
in the engine management system to sta-
bilize the vehicle.

o During ESC operation, a pulsation may
be felt in the brake pedal when the
brakes are applied. Also, a noise may
be heard in the engine compartment
while braking. These conditions are
normal and indicate that the Elec-
tronic Stability Control System is func-
tioning properly.
WARNING:
ESC will not prevent accidents due to
improper or dangerous driving maneu-
vers. Even though vehicle control is im-
proved during emergency braking, al-
ways maintain a safe distance between
you and objects ahead. Vehicle speeds
should always be reduced during ex-
treme road conditions.
The braking distance for cars equipped
with an Electronic Stability Control Sys-
tem may be longer than for those without
it in the following road conditions.
During these conditions the vehicle
should be driven at reduced speeds:
!
C310D01NF-AATIndicators and WarningThe indicators should illuminate when the
ignition key is turned to ON or START but
should go out after three seconds.
If the indicators do not illuminate, or the
ESC or ESC-OFF indicator does not go out
after 3 seconds, have the vehicle checked
by an authorized dealer.
Should there be any unusual operation of
the device while driving, the ESC-OFF
indicator illuminates as a warning.
If the ESC-OFF indicator illuminates, drive
your car to a safe place and stop the
engine.
Then, start the engine again to check if the
ESC-OFF indicator goes out.
If the indicator remains lit even after the
engine has been started, have your car
checked by an authorized Hyundai dealer. o Rough, gravel or snow-covered
roads.
o With tire chains installed.
o On roads where the road surface is
pitted or has different surface height.
The safety features of ESC equipped
vehicle should not be tested by high
speed driving or cornering. This could
endanger the safety of yourself or oth-
ers.

o If a tire goes flat while you are driving,
apply the brakes gently and keep the
car 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.
o If your car is equipped with an automatic
transaxle, don't let your car creep for-
ward. To avoid creeping forward, keep
your foot firmly on the brake pedal when
the car is stopped.
o Use caution when parking on a hill.
Firmly engage the parking brake and
place the gear selector lever in "P" (au-
tomatic transaxle) or in first or reverse
gear (manual transaxle). If your car is
facing downhill, turn the front wheels
into the curb to help keep the car from
rolling. If your car is facing uphill, turn
the front wheels away from the curb to
help keep the car from rolling. If there is
no curb or if it is required by other
conditions to keep the car from rolling,
block the wheels.

TICESC130A02A-AAT
WARNING:
o Whenever leaving vehicle or parking,
always set the parking brake as far as
possible and fully engage the vehicle's
transaxle into the park position. Ve-
hicles not fully engaged in park with
the parking brake set are at risk for
moving inadvertently and injuring
yourself or others.
o All vehicles should always have the
parking brake fully engaged when
parking to avoid inadvertent move-
ment of the car which can injure occu-
pants or pedestrians.
o Nothing should be carried on top of
the shelf panel behind the rear seat. If
there were an accident or a sudden
stop, such objects could move for-
ward and cause damage to the ve-
hicle or injure the occupants.o After being parked, check to be sure the
parking brake is not engaged and that
the parking brake indicator light is out
before driving away.
o Driving through water may get the
brakes wet. They can also get wet when
the car is washed. Wet brakes can be
dangerous! Your car will not stop as
quickly if the brakes are wet. Wet brakes
may cause the car to pull to one side. To
dry the brakes, apply the brakes lightly
until the braking action returns to nor-
mal, taking care to keep the car 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 your
Hyundai dealer for assistance.
o Don't coast down hills with the car out of
gear. This is extremely hazardous. Keep
the car 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.
o 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 in-
creases the wear of the brake compo-
nents.

C160D01A-AATCheck Battery and CablesWinter puts additional burdens on the
battery system. Visually inspect the battery
and cables as described in Section 6. The
level of charge in your battery can be
checked by your Hyundai dealer or a ser-
vice station.C160C01A-AATUse High Quality Ethylene Glycol
CoolantYour Hyundai is delivered with high qual-
ity ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubricates
the water pump and prevents freezing. Be
sure to replace or replenish your coolant in
accordance with the maintenance sched-
ule in Section 5. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures an-
ticipated during the winter.
C160B01A-AATSnowy or Icy ConditionsTo drive your vehicle in deep snow, it may
be necessary to use snow tires or to install
tire chains on your tires. If snow tires are
needed, it is necessary to select tires
equivalent in size and type of the original
equipment tires. Failure to do so may ad-
versely affect the safety and handling of
your car. Furthermore, speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially very haz-
ardous practices.
During deceleration, use engine braking
to the fullest extent. Sudden brake applica-
tions on snowy or icy roads may cause
skids to occur. You need to keep sufficient
distance between the vehicle in operation
in front and your vehicle. Also, apply the
brake gently. It should be noted that install-
ing tire chains on the tire will provide a
greater driving force, but will not prevent
side skids.NOTE:Tire chains are not legal in all states.
Check state laws before fitting tire
chains.
C160F02A-AATCheck Spark Plugs and Ignition
SystemInspect your spark plugs and replace them
if necessary. Also check all ignition wiring
and components to be sure they are not
cracked, worn or damaged in any way.C160E01A-AATChange to "Winter Weight" Oil if
NecessaryIn some climates it is recommended that a
lower viscosity "winter weight" oil be used
during cold weather. See Section 9 for
recommendations. If you aren't sure what
weight oil you should use, consult your
Hyundai dealer.

C160J01A-AATDon't Let Ice and Snow Accumulate
UnderneathUnder some conditions, snow and ice can
build up under the fenders and interfere
with the steering. When driving in severe
winter conditions where this may happen,
you should periodically check underneath
the car to be sure the movement of the front
wheels and the steering components is
not obstructed.C160K01A-AATCarry Emergency EquipmentDepending on the severity of the weather
where you drive your car, you should carry
appropriate emergency equipment. Some
of the items you may want to carry include
tire chains, tow straps or chains, flashlight,
emergency flares, sand, a shovel, jumper
cables, a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
C160G01A-GATTo Keep Locks from FreezingTo keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into the
key opening. If a lock is covered with ice,
squirt it with an approved de-icing fluid to
remove the ice. If the lock is frozen inter-
nally, you may be able to thaw it out by
using a heated key. Handle the heated key
with care to avoid injury.NOTE:The proper temperature for using the
immobilizer key is from -40°F (-40°C) to
176°F (80°C). If you heat the immobilizer
key over 176°F (80°C) to open the frozen
lock, it may cause damage to the tran-
sponder in its head.
C160H02A-AATUse Approved Window Washer Anti-
Freeze in SystemTo keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the con-
tainer. Window washer anti-freeze is avail-
able from Hyundai dealers and most auto
parts outlets. Do not use engine coolant or
other types of anti-freeze as these may
damage the paint finish.C160I01L-AATDon't Let Your Parking Brake FreezeUnder some conditions your parking brake
can freeze in the engaged position. 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 the parking brake may
freeze, apply it only temporarily while you
put the gear selector lever in "P" and block
the rear wheels so the car cannot roll. Then
release the parking brake.

WARNING:
USE OF LIGHTSC180A01A-AATCheck your lights regularly for correct op-
eration and always keep them clean. When
driving during the day in conditions of poor
visibility, it is helpful to drive with head-
lights on low beam. This enables you to be
seen, as well as to see.
HIGHER SPEED MOTORINGC170A02A-AATPre-Trip Inspections1. Tires:
Adjust the tire inflation pressures to speci-
fication. 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.NOTE:Never exceed the maximum tire infla-
tion pressure shown on the tires.
WARNING:
o Underinflated or overinflated tires can
cause poor handling, loss of vehicle
control, and sudden tire failure lead-
ing to accidents, injuries, and even
death. Always check tires are prop-
erly inflated before driving. Refer to
pages 2-23 and 8-3 for proper tire
pressures and further information.o Driving on tires with no or insufficient
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 tire
tread before driving your car. Refer to
8-12 for further information and tread
limits.
2. 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.
3. Drive belt:
A loose or damaged drive belt may result
in overheating of the engine.

C190B01S-AATTrailer HitchesSelect the proper hitch and ball combina-
tion, making sure that its location is com-
patible with that of the trailer or vehicle
being towed.
Use a quality non-equalizing hitch which
distributes the tongue load uniformly
throughout the chassis.
The hitch should be bolted securely to the
car and installed by a qualified technician.
DO NOT USE A HITCH DESIGNED FOR
TEMPORARY INSTALLATION AND
NEVER USE ONE THAT ATTACHES
ONLY TO THE BUMPER.
TRAILER OR VEHICLE TOW-
ING!
C190A01TG-AATIf you are considering towing with your car,
you should first check with your State's
Department of Motor Vehicles to deter-
mine 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 your Hyundai dealer for further
details before towing.
CAUTION:
o Do not do any towing with your car
during its first 1,200 miles (2,000 km)
in order to allow the engine to properly
break in. Failure to heed this caution
may result in serious engine or
transaxle damage.
o When towing a trailer, be sure to con-
sult your Hyundai dealer for further
information on additional require-
ments such as a towing kit, etc.
C190C01Y-AATTrailer BrakesIf your trailer is equipped with a braking
system, make sure it conforms to federal
and/or local regulations and that it is prop-
erly installed and operating correctly.NOTE:If you tow a trailer or vehicle, your car will
require more frequent maintenance due
to the additional load. See Maintenance
Under Severe Usage Conditions" on
page 5-6.
CAUTION:
o Never connect a trailer brake system
directly to the vehicle brake system.
o When towing a trailer on steep grades
(in excess of 6%) pay close attention
to the engine coolant temperature
gauge to ensure the engine does not
overheat. If the needle of the coolant
temperature gauge moves across the
dial towards "H" (HOT), pull over and
stop as soon as it is safe to do so, and
allow the engine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.

CAUTION:
The following specifications are recom-
mended when towing a trailer. The loaded
trailer weight cannot safely exceed the
values in the chart below.
WARNING:
o Improperly loading your vehicle and
trailer can seriously affect its steer-
ing and braking performance causing
a crash which could cause serious
injury or death.
o Towing a trailer affects vehicle han-
dling and braking.
o Drive more slowly when towing a trailer
and allow more distance when brak-
ing.
o Be careful when driving in slippery
and windy conditions.
o Be careful when turning and while
driving up and down hills. 3. The front or rear axle weight must not
exceed the Gross Axle Weight Rating
(GAWR) shown on the vehicle identi-
fication plate (see page 8-2). It is pos-
sible that your towing package does
not exceed the GVWR but exceeds
the GAWR. Improper trailer loading
and/or too much luggage in the trunk
can overload the rear axle. Redistrib-
ute the load and check the axle weight
again.
C190F01TG-AATTrailer or Vehicle Towing Tips1. Before towing, check hitch and safety
chain connections as well as proper
operation of the trailer running lights,
brake lights, and turn signals.
2. Always drive your vehicle at a moder-
ate speed. (Less than 60 mph)
3. Trailer towing requires more fuel than
normal conditions.
4. To maintain engine braking efficiency
and electrical charging performance,
do not tow a trailer with the transaxle
engaged in overdrive gear.
5. Always secure items in the trailer to
prevent load shift while driving.
6. Check the condition and air pressure
of all tires on the trailer and your car.
Low tire pressure can seriously affect
the handling. Also check the spare tire.
7. The vehicle/trailer combination is more
affected by crosswind and buffeting.
When being passed by a large vehicle,
keep a constant speed and steer
straight ahead. If there is too much
wind buffeting, slow down to get out of
the other vehicle's air turbulence.
