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.
We recommend that the cabin air filter
be 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 climate control filter
inspections and changes are required.
If the air flow rate suddenly decreases,
we recommend the system be checked
at an authorized HYUNDAI dealer.
Air Conditioning Performance and
Maintenance at Your HYUNDAI
Dealer
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, we
recommend that the system be inspected by
an authorized HYUNDAI dealer.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
WARNING
Vehicles equipped with R-1234yf
Since the refrigerant is
mildly flammable and
operated at high pressure,
the air conditioning system
should only be serviced
by trained and certified
technicians. It is important
that the correct type and
amount of oil and refrigerant
are used.
All refrigerants should be reclaimed
with proper equipment.
Venting refrigerants directly to the
atmosphere is harmful to individuals
and environment. Failure to heed these
warnings can lead to serious injuries.

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 for a few minutes to ensure
maximum system performance.
• 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.

EXTERIOR FEATURES
Roof rack (if equipped)
ONX4050057
Your vehicle may come equipped with
roof rack rails. If your vehicle is equipped
with roof rack rails, you may be able to
add roof rack crossbars as an accessory
(not shown).
NOTICE
If the vehicle is equipped with a
sunroof, be sure not to position cargo
onto the roof side rails in such a way
that it could interfere with sunroof
operation.
NOTICE
• When carrying cargo on the roof side
rails, take the necessary precautions
to make sure the cargo does not
damage the roof of the vehicle.
• When carrying large objects on the
roof side rails, make sure they do
not exceed the overall roof length or
width.
WARNING
• The following specification is the
maximum weight that can be loaded
onto the roof side rails. Distribute the
load as evenly as possible onto the
roof side rails and secure the load
firmly.
Loading cargo or luggage in excess
of the specified weight limit on the
roof side rails may damage your
vehicle.
ROOF SIDE
RAILS 220 lbs. (100 kg)
EVENLY DISTRIBUTED
• The vehicle center of gravity will be
higher when items are loaded onto
the roof side rails. Avoid sudden
starts, braking, sharp turns, abrupt
maneuvers or high speeds that may
result in loss of vehicle control or
rollover resulting in an accident.
• Always drive slowly and turn corners
carefully when carrying items on the
roof side rails. Severe wind updrafts,
caused by passing vehicles or natural
causes, can cause sudden upward
pressure on items loaded on the
roof side rails. This is especially true
when carrying large, flat items such
as wood panels or mattresses. This
could cause the items to fall off the
roof side rails and cause damage to
your vehicle or others around you.
• To prevent damage or loss of cargo
while driving, check frequently
before or while driving to make sure
the items on the roof side rails are
securely fastened.

The indicator in the instrument cluster
displays the shift lever/button position
when the ignition switch is in the ON
position.
WARNING
To reduce the risk of serious injury or
death:
• ALWAYS check the surrounding
areas near your vehicle for people,
especially children, before shifting a
vehicle into D (Drive) or R (Reverse).
• Before leaving the driver’s seat,
always make sure the shift lever
is in the P (Park) position, then set
the parking brake, and place the
ignition switch in the LOCK/OFF
position. Unexpected and sudden
vehicle movement can occur if these
precautions are not followed.
• When using the paddle shifter
(manual shift mode), do not use
engine braking (shifting from a
high gear to lower gear) rapidly on
slippery roads. The vehicle may slip
causing an accident.
P (Park)
Always come to a complete stop before
shifting into P (Park).
To shift from P (Park), you must depress
firmly on the brake pedal and make sure
your foot is off the accelerator pedal.
If you have done all of the above and
still cannot shift the lever out of P
(Park), see "Shift-Lock Release" in this
chapter. (shift lever type)
The shift lever/button must be in P (Park)
before turning the engine off.
WARNING
• Shifting into P (Park) while the
vehicle is in motion may cause you to
lose control of the vehicle.
• After the vehicle has stopped, always
make sure the shift lever is in P
(Park), apply the parking brake, and
turn the engine off.
• When parking on an incline, shift
the gear to P (Park) and apply the
parking brake to prevent the vehicle
from rolling downhill.
• Do not use the P (Park) position in
place of the parking brake.
R (Reverse)
Use this position to drive the vehicle
backward.
NOTICE
Always come to a complete stop before
shifting into or out of R (Reverse); you
may damage the transmission if you
shift into R (Reverse) while the vehicle is
in motion.
When the vehicle is stopped in R
(Reverse) or D (Drive) position, if you
open the driver’s door with the seat
belt unfastened, the gear is shifted to P
(Park) position automatically.
However when the vehicle moves in R
(Reverse) or D (Drive) position, if you
open the driver’s door with the seat belt
unfastened, the gear may be not shifted
to P (Park) position automatically for
protecting the automatic transmission.

Information
• Only the eight forward gears can be
selected. To reverse or park the vehicle,
move the shift lever to the R (Reverse)
or P (Park) position as required.
• Downshifts are made automatically
when the vehicle slows down. When the
vehicle stops, 1st gear is automatically
selected.
• When the engine RPM approaches the
red zone the transmission will upshift
automatically.
•
If the driver presses the lever to + (Up) or - (Down) position, the transmission may not make the requested gear
change if the next gear is outside of
the allowable engine RPM range.
The driver must execute upshifts in
accordance with road conditions,
taking care to keep the engine RPMs
below the red zone.
• When driving on a slippery road, push
the shift lever forward into the + (Up) position. This causes the transmission
to shift into the 2nd gear which is better
for smooth driving on a slippery road.
Push the shift lever to the - (Down) side to shift back to the 1st gear.
Shift-lock release (lever type)
If the shift lever cannot be moved from
the P (Park) position into R (Reverse)
position with the brake pedal depressed,
continue depressing the brake, and then
do the following:

1. Place the ignition switch in the LOCK/
OFF position.
2. Apply the parking brake.
3. Carefully remove the shift lever boots.
4. Move the Shift lever while holding
the release button (1) with a tool (e.g.
flathead screw-driver).
If you need to use the shift-lock release,
we recommend that the system be
inspected by an authorized HYUNDAI
dealer immediately.
