Windshield Washers
ODN8059209KODN8059209K
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. The spray and wiper operation
will continue until you release the lever. If
the washer does not work, you may need

reservoir.
WARNING
When the outside temperature is below
freezing, ALWAYS warm the windshield
using the defroster to help prevent
the washer fluid from freezing on the
windshield and obscuring your vision
which could result in an accident and
serious injury or death.
NOTICE
• To prevent possible damage to the
washer pump, do not operate the
washer when the fluid reservoir is
empty.
• 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
arms and other components, do
not attempt to move the wipers
manually.

Auto Defogging System (Only
for Automatic Climate Control
System, if equipped)
ODN8059215ODN8059215
Auto defogging helps reduce the
possibility of fogging up the inside of the
windshield by automatically sensing the
moisture on inside the windshield.
The auto defogging system operates
when the heater or air conditioning is on.
$872
When the Auto Defogging
System operates, the
indicator will illuminate.
If a high amount of humidity is detected
in the vehicle, the Auto Defogging

The Idle Stop and Go (ISG) system
automatically and temporarily shuts
down the engine when the vehicle
is stopped and idling to improve fuel
efficiency and reduce exhaust gas
emissions. (i.e. red stop light, stop sign,
and traffic jam).
The engine is automatically started upon
satisfying the starting conditions.
The ISG system is always active, when
the engine is running.
Information
When the engine is automatically started
by the ISG system, some warning
lights (i.e. ABS, ESC, ESC OFF, EPS,
and parking brake warning light) may
illuminate for a few seconds due to the
low battery voltage. However, it does
not indicate a malfunction with the ISG
system.
To Activate the ISG System
Prerequisite for activation
The ISG system operates in the following
situations.
• The driver's seatbelt is fastened
• The driver's door and hood are closed
• The brake vacuum pressure is adequate

• The vehicle is driven over a constant speed and stops
• The climate control system satisfies the conditions
• The vehicle is sufficiently warmed up
• The incline is gradual
• The steering wheel is turned less than 180 degrees and then the vehicle
stops
Information
• The ISG system is not
activated, when the
prerequisites to activate
the ISG system are
unsatisfied. In this case,
the ISG OFF button indicator
illuminates, and the auto stop indicator
(
) illuminates in yellow on the
instrument cluster.
• When the above indicator remains
illuminated on the instrument cluster,
have the IGS system checked by an
authorized HYUNDAI dealer.
Auto stop
To stop the engine in idle stop mode
1. Decrease the vehicle speed to 0 mph.
2. Depress the brake pedal with the shift
button in D (Drive) or N (Neutral).

in green on the instrument cluster, when
the engine stops.
Information
The driving speed must reach at least 3
mph (5 km/h) after an idle stop to stop the
engine in idle stop mode again.
In auto stop mode, when the driver
opens the hood, the ISG system will be
deactivated.
