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 the
recirculated air to the fresh outside air
position.
• 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.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system
performance.
• If you operate 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 knob
or button to the
position and fan
speed control to the lower speed.

Cabin air filter
OIK047401L[A] : Outside air, [B] : Recirculated air
[C] : Cabin air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
Have the cabin air filter replaced by an
authorized HYUNDAI dealer according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditioning
system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.

Battery Sensor Deactivation
ODN8A069204
[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.
-Ther

e is a malfunction with the ISG
system.
- The battery is weak.
-The brake vacuum pr

essure 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.
While Driving

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.
While Driving

Emergency Situations
7-8
Tire Pressure Monitoring System
WARNING
Over-inflation or under-inflation can
reduce tire life, adversely affect vehicle
handling, and lead to sudden tire failure
that may cause loss of vehicle control
resulting in an accident.
Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label. If your
vehicle has tires of a different size than
the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on
a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating
properly. The TPMS malfunction
indicator is combined with the low
tire pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that
prevent the TPMS from functioning
properly.
Always check the TPMS malfunction
telltale after replacing one or more tires
or wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
NOTICE
If any of the below happens, have
the system checked by an authorized
HYUNDAI dealer.
1.
The L
ow Tire Pressure TPMS
Malfunction Indicator does not
illuminate for 3 seconds when the
ignition switch is placed to the ON
position or engine is running.
2.

The TPMS M
alfunction Indicator
remains illuminated after blinking for
approximately 1 minute.
3.

The L
ow Tire Pressure LCD display
