The sensor may be limited when: •
The system may not operate for 15
seconds after the vehicle is started or
the camera is initialized

with a foreign object or debris
• The camera lens is contaminated due
to tinted, filmed or coated windshield,
damaged glass, or stuck of foreign
matter (sticker, bug, etc.) on the glass

When external condition is intervened •
The brightness outside changes
suddenly such as when entering or
exiting a tunnel, or when passing under a bridge.
• The brightness outside is too low such

or an oncoming vehicle is reflected on
a wet road surface such as a puddle in
the road.
• The field of view in front is obstructed
by sun glare.
• There is not enough distance between
you and the vehicle in front to be
able to detect the lane marker or the
vehicle ahead is driving on the lane
maker.
• Driving on a steep grade, over a hill, or
when driving on a curved road.
• The adverse road conditions cause
excessive vehicle vibrations while driving.

Limitations of the System
LFA system may operate prematurely
even if the vehicle does not depart from
the intended lane, OR, LFA system may
not assist your steering or warn you if the
vehicle leaves the intended lane under
the following circumstances:

marking from the road surface or the
lane marking is faded or not clearly
marked.

lane, pedestrians lane, etc.)
When external condition is intervened • The brightness outside changes
suddenly such as when entering or
exiting a tunnel, or when passing under a bridge.
• The brightness outside is too low such
as when the headlamps are not on at
night or the vehicle is going through a tunnel.

Smooth Cornering
Avoid braking or gear changing in
corners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at Night
Night driving presents more hazards than
driving in the daylight. Here are some
important tips to remember: • Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
• Adjust your mirrors to reduce the glare
from other driver's headlamps.
• Keep your headlamps clean and
properly aimed. Dirty or improperly
aimed headlamps will make it much
more difficult to see at night.
• Avoid staring directly at the
headlamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your eyes
to readjust to the darkness.
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement: • Slow down and allow extra following
distance. A heavy rainfall makes
it harder to see and increases the
distance needed to stop your vehicle.
• Turn OFF your Cruise Control.
• Replace your windshield wiper blades
when they show signs of streaking or
missing areas on the windshield.
• Tires should be properly maintained
with at least 1.6mm (2/32nds of an
inch) of tread depth. If your tires
do not have enough tread, making
a quick stop on wet pavement can
cause a skid and possibly lead to an
accident. See "Tire replacement" in
chapter 8.
• Turn on your headlamps to make it
easier for others to see you.
• Driving too fast through large puddles
can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
• If you believe your brakes may be wet,
apply them lightly while driving until
normal braking operation returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet.
The risk of hydroplaning increases as
the depth of tire tread decreases, refer
to “Tire replacement” in chapter 8.

While operating your vehicle: •
Note any changes in the sound of the
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 looseness in the
steering wheel, or change in its
straight-ahead position.
• 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 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 engine
coolant reservoir.
• Check the operation of all exterior
lights, including the brake lights, 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. At least twice a year:
(i.e., every Spring and Autumn) •
Check radiator, heater and air
conditioning hoses for leaks or damage.
• Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer a fluid.
• Check headlamp alignment.
• Check muffler, exhaust pipes, shields and clamps.
• Check the seat belts for wear and function.
At least once a year: • Clean body and door drain holes.
• Lubricate door hinges and hood hinges.
• Lubricate door and hood locks and
latches.
• Lubricate door rubber weather strips.
• Lubricate door checker.
• Check the air conditioning system.
• Inspect and lubricate automatic
transmission linkage and controls.
• Clean the battery and terminals.
• Check the brake fluid level.

Instrument Panel Fuse
Replacement
ODN8089015
1. Turn the engine off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside of
the fuse panel cover to locate the
suspected fuse location.
ODN8089016
5. Pull the suspected fuse straight out. Use the removal tool provided in the
engine compartment fuse panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are provided in
the instrument panel fuse panels (or in
the engine compartment fuse panel).
7. Push in a new fuse of the same
rating, and make sure it fits tightly in
the clips. If it fits loosely, consult an
authorized HYUNDAI dealer.
In an emergency, if you do not have a
spare fuse, use a fuse of the same rating
from a circuit you may not need for
operating the vehicle.
If the headlamps or other electrical
components do not work and the fuses
are undamaged, check the fuse panel
in the engine compartment. If a fuse is
blown, it must be replaced with the same
rating.

Maintenance
8-58
Consult an authorized HYUNDAI dealer
to replace most vehicle light bulbs. It is
difficult to replace vehicle light bulbs
because other parts of the vehicle must
be removed before you can get to the
bulb. This is especially true for removing
the headlamp assembly to get to the
bulb(s).
Removing/installing the headlamp
assembly can result in damage to the
vehicle.
Information
The headlamp and tail lamp lenses could
appear frosty if the vehicle is washed after
driving or the vehicle is driven at night
in wet weather. This condition is caused
by temperature difference between the lamp inside and outside and, it does not
indicate a problem with your vehicle.
When moisture condenses in the lamp,
it will be removed after driving with the
headlamp on. The removable level may
differ depending on lamp size, lamp
position and environmental condition.
However, if moisture is not removed, we
recommend that your vehicle is inspected
by an authorized HYUNDAI dealer.
WARNING
• Prior to replacing a lamp, depress
the foot brake, move the shift button
into P (Park) apply the parking brake,
place the ignition switch to the
LOCK/OFF position, and take the key
with you when leaving the vehicle
to avoid sudden movement of the
vehicle and to prevent possible electric shock.
• Be aware the bulbs may be hot and
may burn your fingers.
