Immobilizer indicator
(if equipped)
Without smart key system
This light illuminates when the immobiliz-
er key is inserted and turned to the ON
position to start the engine.
At this time, you can start the engine. The
light goes out after the engine is running.
If this light blinks when the ignition switch
is in the ON position before starting the
engine, have the system checked by an
authorized HYUNDAI dealer.With smart key system (if equipped)
If any of the following occurs in a vehicle
equipped with the smart key, the immobi-
lizer indicator illuminates, blinks or the
light goes off.
When the smart key is in the vehicle, if
the engine start/stop button is turned
to the ON position, the indicator will
illuminate until the engine is started.
However, when the smart key is not in
the vehicle, if the engine start/stop but-
ton is depressed, the indicator will blink
for a few minutes to indicate that you
will not be able to start the engine.
When the ignition switch is turned to
the ON position and the indicator turns
off after 2 seconds, the system may
need repair. Have the vehicle checked
by an authorized HYUNDAI dealer.
When the battery is weak, if the engine
start/stop button is depressed, the indi-
cator will blink and you will not be able
to start the engine. However, you may
still be able to start the engine by
pressing the engine start/stop button
with the smart key. If smart key system
related parts need repair, the indicator
blinks.
Low fuel level warning light
This warning light indicates the fuel tank
is nearly empty. When it comes on, you
should add fuel as soon as possible.
Driving with the fuel level warning light on
or with the fuel level below “E” can cause
the engine to misfire and damage the
catalytic converter.

Features of your vehicle
Malfunction indicator light
(MIL) (check engine light)
This indicator light is part of the Engine
Control System which monitors various
emission control system components. If
this light illuminates while driving, it indi-
cates that a potential malfunction has
been detected somewhere in the emis-
sion control system.
This light will also illuminate when the
ignition switch is turned to the ON posi-
tion, and will go out in a few seconds
after the engine is started. If it illuminates
while driving, or does not illuminate when
the ignition switch is turned to the ON
position, take your vehicle to your near-
est authorized HYUNDAI dealer and
have the system checked.
Generally, your vehicle will continue to be
drivable, but have the system checked by
an authorized HYUNDAI dealer promptly.
ESC indicator (Electronic
Stability Control)
The ESC indicator will illuminate when
the ignition switch is turned ON, but
should go off after approximately 3 sec-
onds. When the ESC is on, it monitors
the driving conditions. Under normal driv-
ing conditions, the ESC light will remain
off. When a slippery or low traction con-
dition is encountered, the ESC will oper-
ate, and the ESC indicator will blink to
indicate the ESC is operating.
The ESC indicator stays on when the
ESC may have a malfunction. Take your
car to an authorized HYUNDAI dealer
and have the system checked.
ESC OFF indicator
The ESC OFF indicator will illuminate
when the ignition switch is turned ON,
but should go off after approximately 3
seconds. To switch to ESC OFF mode,
press the ESC OFF button. The ESC
OFF indicator will illuminate indicating
the ESC is deactivated.
CAUTION
Prolonged driving with the
Malfunction Indicator Light illumi-
nated may cause damage to the
emission control systems which
could effect drivability and/or fuel
economy.
If the Malfunction Indicator Light
illuminates or blinks, potential
catalytic converter damage is
possible. This could result in loss
of engine power. Have the Engine
Control System inspected as
soon as possible by an author-
ized HYUNDAI dealer.

WARNING- Driving under
the influence of alcohol or
drugs
Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Driving
while under the influence of drugs
is as dangerous or more dangerous
than driving drunk.
You are much more likely to have a
serious accident if you drink or
take drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.
WARNING
When you intend to park or stop
the vehicle with the engine on, be
careful not to depress the accel-
erator pedal for a long period of
time. It may overheat the engine
or exhaust system and cause fire.
When you make a sudden stop or
turn the steering wheel rapidly,
loose objects may drop on the
floor and it could interfere with
the operation of the foot pedals,
possibly causing an accident.
Keep all things in the vehicle
safely stored.
If you do not focus on driving, it
may cause an accident. Be care-
ful when operating what may dis-
turb driving such as audio or
heater. It is the responsibility of
the driver to always drive safely.
WARNING

Driving your vehicle
Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces.
In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
BRAKE SYSTEM
WARNING- Brakes
Do not drive with your foot rest-
ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.
(Continued)
(Continued)
When descending a long or steep
hill, shift to a lower gear and avoid
continuous application of the
brakes. Continuous brake applica-
tion will cause the brakes to over-
heat and could result in a tempo-
rary loss of braking performance.
Wet brakes may impair the vehi-
cle’s ability to safely slow down;
the vehicle may also pull to one
side when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
Always, confirm the position of
the brake and accelerator pedal
before driving. If you don't check
the position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It may
cause a serious accident.
WARNING- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.

Driving your vehicle
24 5
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 igni-
tion 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 while the
engine is running, there may be a mal-
function in the brake system. 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)The ABS continuously senses the speed
of the wheels. If the wheels are going to
lock, the ABS system repeatedly modu-
lates the hydraulic brake pressure to the
wheels.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ABS is active.
In order to obtain the maximum benefit
from your ABS in an emergency situa-
tion, do not attempt to modulate your
brake pressure and do not try to pump
your brakes. Press your brake pedal as
hard as possible or as hard as the situa-
tion warrants and allow the ABS to con-
trol the force being delivered to the
brakes.
WARNING
ABS (or 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 (or 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-covered
roads.
With tire chains installed.
On roads where the road surface
is pitted or has different surface
height.
The safety features of an ABS (or
ESC) equipped vehicle should not
be tested by high speed driving or
cornering. This could endanger the
safety of yourself or others.

Driving your vehicle
After parking the vehicle, check to be
sure the parking brake is not engaged
and that the parking brake indicator
light is out before driving away.
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 light-
ly 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 an author-
ized HYUNDAI dealer for assistance.
Do not 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.
Do not "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 los-
ing their effectiveness. It also increases
the wear of the brake components. 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 slow-
ly enough for it to be safe to do so, pull
off the road and stop in a safe place.
If your vehicle is equipped with an auto-
matic transaxle, don't let your vehicle
creep forward. To avoid creeping for-
ward, keep your foot firmly on the brake
pedal when the vehicle is stopped.
Use caution when parking on a hill.
Firmly engage the parking brake and
place the shift lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle). If your vehicle is
facing downhill, turn the front wheels
into the curb to help keep the vehicle
from rolling. If your vehicle is facing
uphill, turn the front wheels away from
the curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to keep
the vehicle from rolling, block the
wheels. Under some conditions your parking
brake can freeze in the engaged posi-
tion. 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 that the
parking brake may freeze, apply it only
temporarily while you put the gear
selector lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle) and block the rear
wheels so the vehicle cannot roll. Then
release the parking brake.
Do not hold the vehicle on the upgrade
with the accelerator pedal. This can
cause the transaxle to overheat.
Always use the brake pedal or parking
brake.
