Seat belt warning light
Seat belt warning
Driver’s seat belt warning
As a reminder to the driver, the seat
belt warning light will illuminate and
chime for approximately 6 seconds
each time you turn the ignition switch
ON regardless of belt fastening.
If the driver’s seat belt is unfastened
after the ignition switch is ON, the
seat belt warning light illuminates
until the belt is fastened.
OJD032056R
Damaged seat belts and seat
belt assemblies will not operate
properly. Always replace:
Frayed, contaminated, or dam-
aged webbing.
Damaged hardware.
The entire seat belt assembly
after it has been worn in an
accident, even if damage to
webbing or assembly is not
apparent.
WARNING
Seat belts are designed to bear
upon the bony structure of the
body, and should be worn low
across the front of the pelvis or
the pelvis, chest and shoulders,
as applicable; wearing the lap
section of the belt across the
abdominal area must be avoid-
ed.
(Continued)
WARNING
(Continued)
Seat belts should be adjusted
as firmly as possible, consis-
tent with comfort, to provide the
protection for which they have
been designed.
A slack belt will greatly reduce
the protection afforded to the
wearer.
Care should be taken to avoid
contamination of the webbing
with polishes, oils and chemi-
cals, and particularly battery
acid. Cleaning may safely be
carried out using mild soap and
water.
The belt should be replaced if
webbing becomes frayed, con-
taminated or damaged. It is
essential to replace the entire
assembly after it has been worn
in a severe impact even if dam-
age to the assembly is not obvi-
ous. Belts should not be worn
with straps twisted. Each seat
belt assembly must only be used
by one occupant; it is dangerous
to put a belt around a child being
carried on the occupant's lap.

If the Malfunction Indicator Lamp
(MIL) illuminates, potential catalyt-
ic converter damage is possible
which could result in loss of
engine power.
In this case, we recommend that
you have the vehicle inspected by
an authorised HYUNDAI dealer as
soon as possible.
Charging System
Warning Light
When this warning light illuminates
whilst running the engine, the battery
is not being charged. Immediately
turn OFF all electrical accessories.
Try not to use electrically operated
controls, such as the power windows.
Keep running the engine.
We recommend that you have the
vehicle inspected by an authorised
HYUNDAI dealer as soon as possible.
Engine Oil Pressure
Warning Light
This warning light illuminates:
When the engine oil pressure is low.
If the engine oil pressure is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. Turn the engine off and check the
engine oil level (For more informa-
tion, refer to “Engine Oil” in chap-
ter 7). If the level is low, add oil as

able, we recommend that you
have the vehicle inspected by an
authorised HYUNDAI dealer as
soon as possible.

Convenient features of your vehicle
If the engine does not stop
immediately after the Engine Oil
Pressure Warning Light is illumi-
nated, severe damage could
result.
If the warning light stays on
whilst the engine is running, it
indicates that there may be seri-
ous engine damage or malfunc-
tion. In this case:
1. Stop the vehicle as soon as it
is safe to do so.
2. Turn off the engine and check
the oil level. If the oil level is
low, fill the engine oil to the
proper level.
3. Start the engine again. If the

Low Fuel Level
Warning Light
This warning light illuminates:
When the fuel tank is nearly empty.
Add fuel as soon as possible.
Driving with the Low Fuel Level
warning light on or with the fuel
level below "0 or E" can cause the
engine to misfire and damage the
catalytic converter (if equipped).
Engine Coolant
Temperature Warning
Light
This warning light illuminates:
When the engine coolant tempera-
ture is above 120°C (248°F). This
means that the engine is overheat-
ed and may be damaged.
If your vehicle is overheated, refer
to “Overheating” in chapter 6.
Overspeed Warning
Light (if equipped)
This warning light blinks:
When you drive the vehicle more
than 120 km/h.

The refrigerant system should
only be serviced by trained and
certified technicians to insure
proper and safe operation.
The refrigerant system should
be serviced in a well-ventilated
place.
The air conditioning evaporator
(cooling coil) shall never be
repaired or replaced with one
removed from a used or sal-
vaged vehicle and new replace-
ment MAC evaporators shall be
certified (and labelled) as meet-
ing SAE Standard J2842.
Information
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely whilst driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine
overheating. Continue to use the fan
but turn the air conditioning system
off if the temperature gauge indi-
cates engine overheating.
• When opening the windows in
humid weather, air conditioning
may create water droplets inside the
vehicle. Since excessive water
droplets may cause damage to elec-
trical equipment, air conditioning
should only be used with the win-
dows closed.
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.
Use air conditioning to reduce
humidity and moisture inside the
vehicle on rainy or humid days.
During air conditioning system
operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.
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 sys-
tem operation characteristic.

Vehicles equipped with
R-1234yf
Because the refriger-
ant is mildly inflam-
mable at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and
certified technicians.
It is important that the
correct type and amount of oil
and refrigerant is used.
Otherwise, it may cause dam-
age to the vehicle and personal
injury.
WARNINGChecking the amount of air con-
ditioner refrigerant and com-
pressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorised
HYUNDAI dealer.

label in the vehicle may differ from the

Luggage net (holder)
(if equipped)
To keep items from shifting in the lug-
gage compartment, you can use the
four holders located in the luggage
compartment area to attach the lug-
gage net.
If necessary, we recommend that you
contact your authorised HYUNDAI
dealer to obtain a luggage net.To avoid eye injury, DO NOT
overstretch the luggage net.
ALWAYS keep your face and
body out of the luggage net’s
recoil path. DO NOT use the lug-
gage net when the strap has vis-
ible signs of wear or damage.
WARNING
To prevent damage to the goods
or the vehicle, care should be
taken when carrying fragile or
bulky objects in the luggage
compartment.
CAUTION
OAE046431AU
The following must be observed
when installing ANY floor mat
to the vehicle.
Ensure that the floor mats are
securely attached to the vehi-
cle's floor mat anchor(s)
before driving the vehicle.
Do not use ANY floor mat that
cannot be firmly attached to
the vehicle's floor mat anchors.
Do not stack floor mats on top
of one another (e.g. all-weath-
er rubber mat on top of a car-
peted floor mat). Only a single
floor mat should be installed
in each position.
IMPORTANT - Your vehicle was
manufactured with driver's side
floor mat anchors that are
designed to securely hold the
floor mat in place. To avoid any
interference with pedal operation,
HYUNDAI recommends that the
HYUNDAI floor mat designed for
use in your vehicle be installed.
