Air conditioning system operation tips
• If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
• After sufficient cooling has been
achieved, switch back from
recirculation mode to fresh mode.
• To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.
• During air conditioning system
operation, you may occasionally
notice a slight change in engine speed
as the air conditioning compressor
cycles. This is a normal system
operation characteristic.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system
performance.
• When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side of
the vehicle. This is a normal system
operation characteristic.
• If you operate the air conditioner
excessively, 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. In this
case, set the mode selection button to
the
position and set the fan speed
control knob to the lowest speed
setting.

Brake SyStem
Power 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.
Only pump the brakes on slippery
surfaces if the power assist has been
interrupted to maintain steering control.
Do not pump the brakes on slippery
surfaces if the brakes are operating
normally.
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, move the gear shift button
to Manual Shift Mode 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.

Battery Sensor Deactivation
OCN7060158N
[A] : Battery sensor
The battery sensor is deactivated, when
the battery is disconnected from the
negative pole for maintenance purpose.
In this case, the ISG system is limitedly
operated due to the battery sensor
deactivation. Thus, the driver needs
to take the following procedures to
reactivate the battery sensor after
disconnecting the battery.
Prerequisites to reactivate the
battery sensor
Switch "ON" and "OFF" the ignition one
time. Park the vehicle for a minimum of 4
hours with the hood and all doors closed.
Pay extreme caution not to connect any
accessories (i.e. navigation and black
box) to the vehicle with the engine in the
OFF status. If not, the battery sensor may
not be reactivated.
Information
The ISG system may not operate in the
following situations.
-There is a malfunction with the ISG
system.
-The battery is weak.
-The brake vacuum pressur

e is low.
If this occurs, have the ISG system
checked by an authorized HYUNDAI
dealer.
NOTICE
• Use only a genuine HYUNDAI
Absorbent Glass Mat (AGM) battery
for replacement. If not, the ISG
system may not operate normally.
• Do not recharge the Absorbent Glass
Mat (AGM) battery with a general
battery charger. It may damage or
explode the Absorbent Glass Mat
(AGM) battery.
• Do not remove the battery cap. The
battery electrolyte, which is harmful
to the human body, may leak out.

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 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
Tread" 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 Tread" in chapter 8.

WARNING
The use of tire chains may adversely
affect vehicle handling:
• Drive less than 20 mph (30 km/h)
or the chain manufacturer's
recommended speed limit,
whichever is lower.
• Drive carefully and avoid bumps,
holes, sharp turns, and other road
hazards, which may cause the
vehicle to bounce.
• Avoid sharp turns or locked wheel
braking.
Information
• Install tire chains on both left and right
front tires. It should be noted that
installing tire chains on the tires will
provide a greater driving force, but will
not prevent side skids.
• Do not install studded tires without
first checking local, state and municipal
regulations for possible restrictions
against their use.
Chain installation
When installing tire chains, follow the
manufacturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 20 mph (30 km/h)) with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tire chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if
available). Always place the vehicle in P
(Park), apply the parking brake and turn
off the engine before installing snow
chains.
NOTICE
When using tire chains:
• Wrong size chains or improperly
installed chains can damage your
vehicle's brake lines, suspension,
body and wheels.
• Use SAE "S" class or wire chains.
• If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.
• To prevent body damage, retighten
the chains after driving 0.3~0.6 miles
(0.5~1.0 km).
• Do not use tire chains on vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.
• Use wire chains less than 0.59 inch
(15mm) wide to prevent damage to
the chain’s connection.
Winter Precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 8. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
