CAUTION
Always be sure to clean the area around any filler plug, drain plug, or dipstick before
checking or draining any lubricant. This is especially important in dusty or sandy
areas and when the vehicle is used on unpaved roads. Cleaning the plug and dipstick
areas will prevent dirt and grit from entering the engine and other mechanisms that
could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather
operating (engine start and engine oil flowability). Lower viscosity engine oils can
provide better fuel economy and cold weather performance, however, higher viscosity
engine oils are required for satisfactory lubrication in hot weather. Using oils of any
viscosity other than those recommended could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be operated
in before the next oil change. Proceed to select the recommended oil viscosity from
the chart.

System Maintenance
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.
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.
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,
the system is 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
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the
oil or for any other purpose. If you hear a change in the sound of the exhaust or if
you drive over something that strikes the underneath side of the vehicle, the exhaust
system be checked as soon as possible by an authorized HYUNDAI dealer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous
practice. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle, be sure to do so only in an open area with the air intake set at “Fresh” and fan
control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windshield clear of snow, ice, leaves, or other obstructions.
If you must drive with the liftgate open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at “Fresh”, the air flow control at “Floor” or “Face”, and the fan
control set to high.

Chain Installation
When installing tire chains, follow the
manuf
acturer’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 0.47 in.
(12 mm) thick or fabric-type chain
to prevent damage to the chain’s
connection.

[ Fabric-type chains must be used on
vehicles equipped with 19/20” tires.
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 9. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked
by an authorized HYUNDAI dealer or in a
service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not sure
about a type of winter weight oil, you
consult an authorized HYUNDAI dealer.

Information

[ As it is normal for engine oil to be consumed during driving, the engine oil level should
be checked on regular basis.

[ The engine oil change interval for normal operating conditions is based on the use of
the recommended engine specification. If the recommended engine oil specification
is not used, then replace the engine oil according to the maintenance schedule under
severe operating conditions.

[ The vehicle may be equipped with the Oil Life Management System that predicts
engine oil life based on the driver’s driving history and alerts the driver to change
engine oil.
- If the deterioration of the engine oil increases depending on the driver’s driving
style, the remaining oil life alert will appear on the instrument cluster before the
normal engine oil replacement interval. Have the engine oil and filter changed by an
authorized HYUNDAI dealer.
- Oil Life Management System works when the recommended engine oil is used.
If the recommended engine oil is not used, replace the engine oil according to the
maintenance schedule under severe usage conditions. Also, check the engine oil level
regularly as this system assumes that the engine oil is being filled norm\
ally.
- Always reset the remaining engine oil life whenever the engine oil is changed.
Otherwise, the indication of remaining Oil life in the Oil Life Management System
may not be accurate.To reset the Oil Change Reminder, select ‘RESET’ from the
instrument cluster or infotainment system screen. Then, select ‘Yes’ when the
message “Reset oil life?” or “Has the engine oil been changed? Press [Yes] to reset
the oil life.” appears on the screen.
- If there is no alert until the maximum maintenance interval, have the vehicle
checked by an authorized HYUNDAI dealer.
