WARNING
Windshield heating
Do not use the
position during cooling operation in extremely humid
weather. The difference between the
temperature of the outside air and that
of the windshield could cause the outer
surface of the windshield to fog up,
causing loss of visibility could cause
an accident resulting in serious injury
or death. In this case, set the mode
selection button to the
position and fan speed control knob to a lower
speed.
• For maximum defrost performance,
set the temperature control to the
highest temperature setting and
the fan speed control to the highest
setting.
• If warm air to the floor is desired while
defrosting or defogging, set the mode
to the floor-defrost position.
• Before driving, clear all snow and ice
from the windshield, rear window,
side view mirrors, and all side
windows.
• Clear all snow and ice from the
hood and air inlet in the cowl grill
to improve heater and defroster
efficiency and to reduce the
probability of fogging up the inside of
the windshield.
NOTICE
If the engine temperature is still cold
after starting, then a brief engine warm
up period may be required for the
vented air flow to become warm or hot.

Auto Defogging System
on Models with Automatic
Temperature Control
Auto defogging help 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.
Information

operate normally, when the outside
temperature is below 14°F(-10°C).
To cancel or set the Auto Defogging
System, keep the front defroster button
pressed for 3 seconds. The “ADS OFF”
symbol will be shown in the climate
display to inform you that the system
is deactivated. To re-activate the auto
defogging system, follow the procedure
mentioned above and the “ADS OFF”
symbol will disappear.
If the battery has been disconnected
or discharged, it resets to the auto
defogging status.
Information
For efficiency, do not select recirculated
air position while the Auto defogging
system is operating.
NOTICE
Do not remove the sensor cover located
on the top of the windshield glass.
Damage to system parts could occur
and may not be covered by your vehicle
warranty.

BRAKING SYSTEM
Power-assist brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. You can still
stop your vehicle by applying greater
force to the brake pedal than typical.
The stopping distance, however, will be
longer than with power brakes.
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.
WARNING
Take the following precautions:
• Do not drive with your foot resting
on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances.
• When descending down a long or
steep hill, use the paddle shifter
and manually downshift to a
lower gear in order to control your
speed without using the brake
pedal excessively. Applying the
brakes continuously will cause
the brakes to overheat and could
result in a temporary loss of braking
performance.
• Wet brakes may impair the vehicle'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 fashion after driving
through deep water. To dry the
brakes, lightly tap the brake pedal to
heat up the brakes while maintaining
a safe forward speed until brake
performance returns to normal.
Avoid driving at high speeds until the
brakes function correctly.
Disc brakes wear indicator
When your brake pads are worn and new
pads are required, you will hear a high
pitched warning sound from your front
or rear brakes. You may hear this sound
come and go or it may occur whenever
you depress the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does not
indicate a problem with your brakes.
NOTICE
To avoid costly brake repairs, do not
continue to drive with worn brake pads.
Information
Always replace brake pads as complete
front or rear axle sets.

Driving your vehicle6-44
IDLE STOP AND GO (ISG) SYSTEM
Idle Stop and Go helps reduce fuel
consumption by automatically shutting
down the engine, when the vehicle is
at a standstill (i.e. red stop light, stop
sign, and traffic jam) subject to certain
prerequisite conditions being satisfied as
listed below.
The engine is automatically started upon
satisfying the starting conditions.
ISG system is always active, when the
engine is running.
Information
When the engine is automatically started
by ISG system, warning lights (i.e. ABS,
ESC, ESC OFF, EPS, and parking brake
warning light) may illuminate for a few
seconds due to low battery voltage.
However, it does not indicate a
malfunction with ISG system.
ISG system operation
Prerequisite for activation
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 battery sensor is activated and
the battery is sufficiently charged
• Outside temperature is not too low or
too high
• The vehicle is driven over a constant
speed and stops
• The climate control system satisfies
the conditions
• The vehicle is sufficiently warmed up
• ISG related parts are working properly
• The incline is gradual
• The steering wheel is turned less than
180 degrees and then the vehicle
stops
Information
If the ISG light (white) is turned on on the
instrument cluster and does not meet the
ISG system operating conditions, the ISG
system is not activated.
When the ISG light (yellow) is on while the
ISG system meets operating conditions, we
recommend that the system be inspected
by an authorized HYUNDAI dealer.
