Brake) does not release:
Contact an authorized HYUNDAI
dealer by loading the vehicle on a
flatbed tow truck and have the sys-
tem checked.
EPB (Electronic Parking Brake)
may be automatically applied

Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering maneuvers.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle's brakes
and intervenes in the engine man-
agement system to assist the driver
with keeping the vehicle on the
intended path. It is not a substitute
for safe driving practices. Always
adjust your speed and driving to the
road conditions.
ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately three seconds and goes off,
then the ESC is turned on.
When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
When you apply your brakes under conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This
is normal and it means your ESC is
active.
When the ESC activates, the engine may not respond to the
accelerator as it does under rou-
tine conditions.
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning
on wet surfaces can result in
severe accidents.

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 skids to occur.
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.

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 acceleratorpedal 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.

If any of the below happens, have
the system checked by an author-
ized HYUNDAI dealer.
1. The Low Tire Pressure Telltale/TPMS Malfunction Indicator
does not illuminate for 3 sec-
onds 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 Position Telltale remains illuminated.

Position and Tire
Pressure Telltale
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 will indi-
cate which tire is significantly under-
inflated by illuminating the corre-
sponding 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 the spare tire.
The Low Tire Pressure Telltale will
remain on and the TPMS Malfunction
Indicator may blink for one minute
and then remain illuminated (when
the vehicle is driven approximately
20 minutes at speed above 15.5 mph
(25 km/h)) until you have the low
pressure tire repaired and replaced
on the vehicle.
Information
The spare tire is not equipped with a
tire pressure sensor.

Maintenance
Owner Maintenance Schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check 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 /ecoshift dual clutch 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 stoplights, 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
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and fusible link 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
system.
CAUTION
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.
