vehicle equipped with the smart key,
the immobilizer 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 indi-
cator will illuminate until the engine
is started. However, when the smart
key is not in the vehicle, if the engine
start/stop button is depressed, the

start the engine.
When the ignition switch is turned to the ON position and the indica-
tor turns off after 2 seconds, the

engine start/stop button is
depressed, the indicator 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 indi-
cator blinks.Low fuel level warning

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

Malfunction indicatorlight (MIL)(check engine light)
This indicator light is part of the
Engine Control System which moni-
tors various emission control system
components. If this light illuminates
while driving, it indicates that a
potential malfunction has been
detected somewhere in the emission
control system.
This light will also illuminate when
the ignition switch is turned to the
ON position, 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 nearest
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 StabilityControl)
The ESC indicator will illuminate
when the ignition switch is turned
ON, but should go off after approxi-
mately 3 seconds. When the ESC is
on, it monitors the driving conditions.
Under normal driving conditions, the
ESC light will remain off. When a slip-
pery or low traction condition is
encountered, the ESC will operate,
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.
CAUTION
Prolonged driving with the Malfunction Indicator Lightilluminated may cause damageto the emission control sys-tems which could effect dri-vability and/or fuel economy.
If the Malfunction Indicator Light illuminates or blinks,potential catalytic converterdamage is possible. Thiscould result in loss of enginepower. Have the EngineControl System inspected assoon as possible by anauthorized HYUNDAI dealer.

LO : Normal wiper speed
HI : Fast wiper speed
✽ ✽NOTICE
If there is heavy accumulation of
snow or ice on the windshield,
defrost the windshield for about 10
minutes, or until the snow and/or ice
is removed before using the wind-
shield wipers to ensure proper oper-
ation.
✽ ✽NOTICE
• When you operate the wipers, if
your vehicle has a problem in any
part of the wiper operation sys-
tem, the wiper may operate in the
LO mode regardless of the wiper
switch position. In this case, have
your vehicle checked by an
authorized HYUNDAI dealer as
soon as possible.
• When the ignition key is removed, the wiper blade sometimes may
move slightly for reducing the
deterioration of the windshield
wipers.
Windshield washers
In the OFF position, pull the lever
gently toward you to spray washer
fluid on the windshield and to run the
wipers 1-3 cycles.
Use this function when the wind-
shield is dirty.
The spray and wiper operation will
continue until you release the lever.
If the washer does not work, check
the washer fluid level. If the fluid level
is not sufficient, you will need to add
appropriate non-abrasive windshield
washer fluid to the washer reservoir. The reservoir filler neck is located in
the front of the engine compartment
on the passenger side.

CAUTION
To prevent possible damage to
the washer pump, do not oper-ate the washer when the fluidreservoir is empty.
WARNING
Do not use the washer in freez-
ing temperatures without first
warming the windshield with
the defrosters; the washer solu-
tion could freeze on the wind-
shield and obscure your vision.

BEFORE DRIVING
CALIFORNIA PROPO-
SITION 65 WARNING
Engine exhaust and a wide vari-
ety of automobile components
and parts, including compo-
nents found in the interior fur-
nishings in a vehicle, contain or
emit chemicals known to the
State of California to cause can-
cer and birth defects and repro-
ductive harm. In addition, cer-
tain fluids contained in vehicles
and certain products of compo-
nent wear contain or emit chem-
icals known to the State of
California to cause cancer and
birth defects or other reproduc-
tive harm.
WARNING
Driving while distracted can
result in a loss of vehicle con-
trol, that may lead to an accident,
severe personal injury, and
death. The driver’s primary
responsibility is in the safe and
legal operation of a vehicle, and
use of any handheld devices,
other equipment, or vehicle sys-
tems which take the driver’s
eyes, attention and focus away
from the safe operation of a vehi-
cle or which are not permissible
by law should never be used
during operation of the vehicle.

WARNING -
Driving under the influence
of alcohol or drugs
Drinking and driving is danger-
ous. Impaired driving is the
number one contributor to the
highway death toll each year.
Even a small amount of alcohol
will affect your reflexes, percep-
tions 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 driver who has been drink-
ing or taking drugs. Choose a
designated driver or call a cab.
WARNING
All passengers must be proper-
ly belted whenever the vehicle
is moving. Refer to “Seat belts”
in section 3 for more informa-
tion on their proper use.
WARNING
When you intend to park or stop the vehicle with the
engine on, be careful not to
depress the accelerator 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 opera-
tion of the foot pedals, possi-
bly causing an accident. Keep
all things in the vehicle safely
stored.
If you do not focus on driving, it may cause an accident. Be
careful when operating
devices that may disturb driv-
ing such as the audio system
or the heater. It is the respon-
sibility of the driver to always
drive safely.

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 normally would. The
stopping distance, however, 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.
BRAKE SYSTEM
WARNING- Brakes
Do not drive with your foot resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
When descending a long or steep hill, shift to a lower gear
(for automatic transaxle,
move the shift lever to sports
mode) and avoid continuous
application of the brakes.
Continuous brake application
will cause the brakes to over-
heat and could result in a tem-
porary loss of braking per-
formance.
(Continued)(Continued)
Wet brakes may impair thevehicle’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 fash-
ion 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.
