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 windshield is
dirty.
The spray and wiper operation will con-
tinue 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 appropri-
ate 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 operate the
washer when the fluid reservoir is
empty.
WARNING
Do not use the washer in freezing
temperatures without first warming
the windshield with the defrosters;
the washer solution could freeze on
contact with the windshield and
obscure your vision.
CAUTION
To prevent possible damage to
the wipers or windshield, do not
operate the wipers when the
windshield is dry.
To prevent damage to the wiper
blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.
To prevent damage to the wiper
arms and other components, do
not attempt to move the wipers
manually.

WARNING- ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the win-
dows immediately.
• Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxia-
tion.

The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear
a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have the
exhaust system checked as soon as possible by an authorized HYUNDAI dealer.

Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your
garage any longer than it takes to start the vehicle and back the car out.

If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area
with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk lid open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshield are
kept clear of snow, ice, leaves or other obstructions.

you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil, engine
coolant, brake fluid, and washer fluid
should be checked on a regular basis,
with the exact interval depending on the
fluid. Further details are provided in sec-
tion 7, “Maintenance”.
