Exhaust System (GPF)Warning Light (for petrol engine,if equipped)
This warning light illuminates:
When there is a malfunction with
the Gasoline (Petrol) Particulate
Filter (GPF) system.
When this warning light illumi-
nates, it may turn off after driving
the vehicle:
- At more than 50 mph (80 km/h) forabout 30 minutes
(above 3rd gear with 1500 ~ 4000
engine rpm)
If this warning light blinks in spite of
the procedure (at this time LCD
warning message will be displayed),
we recommend that you have the
GPF system checked by a HYUNDAI
authorised repairer.
If you continue to drive with the
GPF warning light blinking for a
long time, the GPF system can be
damaged and fuel consumption
can worsen.

This warning message is displayed
when the engine coolant tempera-
ture is above 120°C (248°F). This
means that the engine is overheated
and may be damaged.
If your vehicle is overheated, refer
to "Overheating" in chapter 6.
Check exhaust system (if equipped)
This warning message illuminates if
the GPF system has a malfunction.
at this time, GPF warning light also
blinks.
In this case, we recommend that you
have the GPF system checked by a
HYUNDAI authorised repairer.

Air conditioning system operation
tips
If the vehicle has been parked indirect 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 the vehicle. This is a normal
system operation characteristic. Operating the air conditioning sys-
tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.
System maintenance
Climate control air filter
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
screen even when the outside (fresh)
air position is selected. If this hap-
pens, we recommend that the cli-
mate control air filter be replaced by
a HYUNDAI authorised repairer.

Information
• Replace the filter according to theMaintenance Schedule.
If the car is being driven in severe
conditions such as dusty, rough
roads, more frequent climate con-
trol air filter inspections and
changes are required.
• When the air flow rate suddenly decreases, we recommend that the
system be checked by a HYUNDAI
authorised repairer.
Checking 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 on the
air conditioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by a HYUNDAI
authorised repairer.
i
Vehicles equipped with R-134a
Because the refriger-
ant is 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 damage
to the vehicle and personal injury.
WARNING
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.

Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions, more frequent oil and filter
changes are required.
HSG (Hybrid starter & genera-
tor) belt
The HSG belt should be changed at
the intervals specified in the mainte-
nance schedule.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend a HYUNDAI
authorised repairer replace any dam-
aged or leaking parts immediately.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently. After
installing a new filter, run the engine
for several minutes, and check for
leaks at the connections. Fuel filters
should be installed by a HYUNDAI
authorised repairer.
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vapour
hose or fuel filler cap is correctly
replaced.
Air cleaner filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant/inverter
coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.

7-12
Maintenance
Use only the specified engine oil
(Refer to “Recommended Lubricants
and Capacities” in chapter 8).
Checking the engine oil and
filter
We recommend that the engine oil
and filter be changed by a HYUNDAI
authorised repairer according to the
Maintenance Schedule.

Checking the parking brake
Foot type (if equipped)
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 20 kg (44 lb,
196 N) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade. If the
stroke is more or less than specified,
have the parking brake adjusted by a
HYUNDAI authorised repairer.
Stroke : 4~5 notch
Filter replacement
The air cleaner filter can be cleaned
for inspection using compressed air.
Do not attempt to wash or to rinse it,
as water will damage the filter.
If soiled, the air cleaner filter must be
replaced.OAE056014R

To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility
when sprayed on the wind-
screen and may cause loss of
vehicle control resulting in an
accident or damage to paint
and body trim.
Do not allow sparks or flames
to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may contain
alcohol and can be flamma-
ble.
Do not drink washer fluid and
avoid contact with skin.
Washer fluid is poisonous to
humans and animals.
Keep washer fluid away from
children and animals.
