LIGHT BULBS
Use only bulbs of the specified wattage.
✽
✽
NOTICE
After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between the
lamp inside and outside. This is similar
to the condensation on your windows
inside your vehicle during the rain and
doesn’t indicate a problem with your
vehicle. If the water leaks into the lamp
bulb circuitry, have the vehicle checked
by an authorized HYUNDAI dealer.
WARNING - Working on
the lights
Prior to working on the light, firmly
apply the parking brake, ensure
that the engine start/stop button is
in the OFF position and turn off the
lights to avoid sudden movement
of the vehicle and burning your fin-
gers or receiving an electric shock.
CAUTION
Be sure to replace the burned-out
bulb with one of the same wattage
rating. Otherwise, it may cause
damage to the fuse or electric
wiring system.CAUTION
If you don’t have necessary tools,
the correct bulbs and the expertise,
consult an authorized HYUNDAI
dealer. In many cases, 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 if you have to remove the head-
light assembly to
get to the bulb(s).
Removing/installingthe headlight
assembly can result in damage to
the vehicle.
WARNING
When you replace the front head-
lamp bulb be careful of the HPCU
system, the high voltage cable
(orange color), and high voltage
components for the hybrid system.
It is very dangerous because the
HPCU has high voltage. Do not
touch those high voltage systems
or it could result in the electric
shock or burns or even death.
CAUTION
If your vehicle is equipped with
High Intensity Discharge (HID)
headlights, these headlights con-
tain mercury. So if you need to have
your vehicle disposed, you should
remove the HID Headlights before
disposal. The removed HID head-
lights should be recycled, re-used
or disposed as hazardous waste.

APPEARANCE CARE
Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.
Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are kept
clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
CAUTION
Do not use strong soap, chemical
detergents or hot water, and do
not wash the vehicle in direct
sunlight or when the body of the
vehicle is warm.
Be careful when washing the side
windows of your vehicle.
Especially, with high-pressure
water, water may leak through the
windows and wet the interior.
To prevent damage to the plastic
parts and lamps, do not clean
with chemical solvents or strong
detergents.
WARNING
Do not wash the engine compart-
ment and trunk with water. The
hybrid system is located in the
engine compartment and trunk. If
water enters the engine or hybrid
battery in the trunk, electric shocks
or burns may result in serious injury
or death.
CAUTION
Never allow water or other liquids
to come in contact with
electrical/electronic components
and air ducts inside the vehicle as
this may damage them.

Maintenance
Aluminum or chrome wheel mainte-
nance
The aluminum or chrome wheels are
coated with a clear protective finish.
Do not use any abrasive cleaner, polish-
ing compound, solvent, or wire brushes
on aluminum or chrome wheels. They
may scratch or damage the finish.
Clean the wheel when it has cooled.
Use only a mild soap or neutral deter-
gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
Avoid washing the wheels with high-
speed car wash brushes.
Do not use any cleaners containing
alkaline or acid detergents. It may
damage and corrode the aluminum or
chrome wheels coated with a clear
protective finish.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design and
construction practices to combat corro-
sion, we produce cars of the highest
quality. However, this is only part of the
job. To achieve the long-term corrosion
resistance your vehicle can deliver, the
owner's cooperation and assistance is
also required.
Common causes of corrosion
The most common causes of corrosion
on your car are:

allowed to accumulate underneath the
car.
Removal of paint or protective coatings
by stones, gravel, abrasion or minor
scrapes and dents which leave unpro-
tected metal exposed to corrosion.WARNING
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.
CAUTION
Do not wash or drive the vehicle
with the under cover removed.
Doing so, could result in damage of
the hybrid system.

ECONOMICAL and SAFE OPERA-
TION of Hybrid system
Drive smoothly. Accelerate at a moder-
ate rate and maintain a steady cruising
speed. Don't make "jack-rabbit" starts.
Don't race between stoplights.
Avoid heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary braking. This also reduces
brake wear.
The regenerative brake generates
energy when the vehicle decelerates.
When the hybrid battery power is low,
the hybrid system automatically
recharges the hybrid battery.
When the engine runs in "N" position,
the hybrid system can not generate
electricity. The hybrid battery cannot
recharge in "N" position. Please check
Chapter 5.

trunk as shown should always be pulled
out to disconnect and turn off the hybrid
system.
IMPORTANT: Wait 5 minutes after this
lever is disconnected to work on the
car to assure all remaining charge in
the system has dissipated.
The special features of hybrid
vehicle.
Hybrid vehicles sound different than
gasoline engine vehicles. When the
hybrid system operates, you may hear a
sound from the hybrid battery system
behind the rear seat. If you apply the
accelerator pedal rapidly, you may hear
an unconventional sound. When you
apply the brake pedal, you may hear a
sound from the regenerative brake sys-
tem. When the hybrid system is turned
off or on, you may hear a sound in the
engine compartment. If you depress the
brake pedal repeatedly when the hybrid
system is turned on, you may hear a
sound in the engine compartment. None
of these sounds indicate a problem.
These are normal characteristics of
hybrid vehicles.
If any of following occur, it's a normal
condition if you hear a motor sound in the
engine compartment:
- After turning off the hybrid system, the
brake pedal is released.
- When the hybrid system is turned off,
the brake pedal is applied.
- When the driver door is opened.
