Indicator light
When ignition switch is turned to the ON
position, the indicator light illuminates,
then goes off if the ESC system is oper-
ating normally.
The ESC indicator light blinks whenever
ESC is operating or illuminates when
ESC fails to operate.
The ESC OFF indicator light comes on
when the ESC is turned off with the but-
ton.
ESC OFF usage
When driving
ESC should be turned on for daily driv-
ing whenever possible.
To turn ESC off while driving, press the ESC OFF button while driving on a flat
road surface.
✽ ✽ NOTICE
• When operating the vehicle on a
dynamometer, ensure that the ESC is
turned off (ESC OFF light illuminat-
ed). If the ESC is left on, it may pre-
vent the vehicle speed from increas-
ing, and result in false diagnosis.
• Turning the ESC off does not affect ABS or brake system operation.
CAUTION
Driving with varying tire or wheel
sizes may cause the ESC system tomalfunction. When replacing tires,make sure they are the same size asyour original tires.
WARNING
The Electronic Stability Control sys-
tem is only a driving aid; use pre-
cautions for safe driving by slowing
down on curved, snowy, or icy
roads. Drive slowly and don’t
attempt to accelerate whenever the
ESC indicator light is blinking, or
when the road surface is slippery.

Driving your vehicle
Hill-start assist control (HAC)
(if equipped)
A vehicle has the tendency to slip back
on a steep hill when it starts to go after
stopping. The Hill-start Assist Control
(HAC) prevents the vehicle from slipping
back by operating the brakes automati-
cally for about 2 seconds. The brakes are
released when the accelerator pedal is
depressed or after about 2 seconds.
✽ ✽NOTICE
• The HAC does not operate when the
transaxle shift lever is in the P (Park)
or N (Neutral) position.
• The HAC activates even though the ESC is off but it does not activate
when the ESC has malfunctioned.
Downhill brake control (DBC)
(if equipped)
The Downhill Brake Control (DBC) sup-
ports the driver come down a steep hill
without the driver depressing the brake
pedal. It slows down the vehicle under
5 mph (8 km/h) with the automatic
transaxle or 9 mph (15 km/h) with the
manual transaxle and lets the driver con-
centrate on steering the vehicle.
DBC defaults to the OFF position when-
ever the ignition is turned on.
The DBC can be turned on or off by
pushing the button.

OLM059021LWARNING
The HAC is activated only for about
2 seconds, so when the vehicle is
starting off always depress the
accelerator pedal.

Driving your vehicle
Each of these actions will cancel cruisecontrol operation (the SET indicator lightin the instrument cluster will go off), but itwill not turn the system off. If you wish to resume cruise control operation, moveup the lever (to RES+) located on yoursteering wheel. You will return to your previously preset speed.
To resume cruising speed at
more than approximately 25 mph
(40 km/h):
If any method other than the CRUISE
ON-OFF switch was used to cancel
cruising speed and the system is still
activated, the most recent set speed will
automatically resume when you move
the lever (1) up (to RES+).
It will not resume, however, if the vehicle
speed has dropped below approximately
25 mph (40 km/h).
To turn cruise control off, do one
of the following:
Push the CRUISE ON-OFF button (the CRUISE indicator light in the instru-
ment cluster will go off).
Turn the ignition off.
Both of these actions will cancel the cruise control operation. If you want to resume the cruise control operation,repeat the steps provided in “To set cruise control speed” on the previouspage.

Driving your vehicle
Remember, your vehicle does notrequire 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. Use your air conditioning sparingly.
The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorized
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - Engine off dur- ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
while driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury or
death.

Use high quality ethylene glycol
coolant
Your vehicle is delivered with high quality
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, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in section 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station.
Change to "winter weight" oil if
necessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING- Tire chains
The use of chains may adversely
affect vehicle handling.
Do not exceed 20 mph (30 km/h) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked- wheel braking.
CAUTION
Chains that are the wrong size or improperly installed can damageyour vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

What to do in an emergency
2. When the vehicle is stopped, turn onyour 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 vehicle. Be sure they all get out on the
side of the vehicle that is away from
traffic.
4. When changing a flat tire, follow the instruction provided later in this sec-
tion.
If engine stalls while driving
1. Reduce your speed gradually, keeping a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your vehicle will not start, contact an
authorized HYUNDAI dealer or seek
other qualified assistance.
If engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatictransaxle, be sure the shift lever is in N
(Neutral) or P (Park) and the emer-
gency brake is set.
2. Check the battery connections to be sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you operate the
starter, the battery is discharged.
4. Check the starter connections to be sure they are securely tightened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump starting".
If engine turns over normally but
does not start
1. Check fuel level.
2. With the ignition switch in the LOCKposition, check all connectors at igni-
tion coils and spark plugs. Reconnect
any that may be disconnected or
loose.
3. Check the fuel line in the engine com- partment.
4. If the engine still does not start, call an authorized HYUNDAI dealer or seek
other qualified assistance.
IF THE ENGINE WILL NOT START
WARNING
If the engine will not start, do not
push or pull the vehicle to start it.
This could result in a collision or
cause other damage. In addition,
push or pull starting may cause the
catalytic converter to be over-
loaded and create a fire hazard.

EMERGENCY STARTING
Connect cables in numerical order and
disconnect in reverse order.
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.
CAUTION
Use only a 12-volt jumper system.
You can damage a 12-volt startingmotor, ignition system, and otherelectrical parts beyond repair by use 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.
If these instructions are not fol-
lowed exactly, serious personal
injury and damage to the vehicle
may occur! If you are not sure
how to follow this procedure,
seek qualified assistance.
Automobile batteries contain sul-
furic acid. This is poisonous and
highly corrosive. When jump
starting, wear protective glasses
and be careful not to get acid on
yourself, your clothing or on the
vehicle.
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.

NOTICE
If the TPMS, Low Tire Pressure indi-
cator do not illuminate for 3 seconds
when the ignition switch is turned to
the ON position or engine is running,
or if they remain illuminated after
coming on for approximately 3 sec-
onds, take your vehicle to your near-
est authorized HYUNDAI dealer and
have the system checked.
Low tire pressure tell-
tale
When the tire pressure monitoring
system warning indicator illuminates,
one or more of your tires is signifi-
cantly 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.
Then the TPMS malfunction indicator
may turn on and the Low Tire
Pressure telltale will remain on after
restarting and about 20 minutes of
continuous driving before you have
the low-pressure tire repaired and
replaced on the vehicle.✽ ✽ NOTICE
The compact spare tire is not
equipped with a tire pressure sensor.
