engine oil HYUNDAI I30 2022 Owners Manual

Diesel engine
Diesel fuel
Diesel engine must be operated only
on commercially available diesel fuel
that complies with EN 590 or compa-
rable standard. (EN stands for
"European Norm"). Do not use
marine diesel fuel, heating oils, or
non-approved fuel additives, as this
will increase wear and cause dam-
age to the engine and fuel system.
The use of non-approved fuels and /
or fuel additives will result in a limita-
tion of your warranty rights.
Diesel fuel of above cetane 51 is
used in your vehicle. If two types of
diesel fuel are available, use summer
or winter fuel properly according to
the following temperature conditions.
Above -5°C (23°F) ... Summer typediesel fuel.
Below -5°C (23°F) ... Winter type diesel fuel.
Watch the fuel level in the tank very
carefully : If the engine stops through
fuel failure, the circuits must be com-
pletely purged to permit restarting.
Biodiesel
Commercially supplied Diesel blends
of no more than 7% biodiesel, com-
monly known as "B7 Diesel" may be
used in your vehicle if Biodiesel meets
EN 14214 or equivalent specifications.
(EN stands for "European Norm"). The
use of biofuels exceeding 7% made
from rapeseed methyl ester (RME),
fatty acid methyl ester (FAME), veg-
etable oil methyl ester (VME) etc. or
mixing diesel exceeding 7% with
biodiesel will cause increased wear or
damage to the engine and fuel sys-
tem. Repair or replacement of worn or
damaged components due to the use
of non approved fuels will not be cov-
ered by the manufactures warranty.
F9
Introduction
Do not let any gasoline or water
enter the tank. This would make
it necessary to drain it out and
to bleed the lines to avoid jam-
ming the injection pump and
damaging the engine.
CAUTION
It is recommended to use the
regulated automotive diesel
fuel for diesel vehicle equipped
with the DPF system.
If you use diesel fuel including
high sulfur (more than 50 ppm
sulfur) and unspecified addi-
tives, it can cause the DPF sys-
tem to be damaged and white
smoke can be emitted.
CAUTION
Never use any fuel, whether
diesel, B7 biodiesel or other-
wise, that fails to meet the lat-
est petroleum industry speci-
fication.
Never use any fuel additives
or treatments that are not rec-
ommended or approved by
the vehicle manufacturer.

Operation Tips
To keep dust or unpleasant fumesfrom entering the vehicle through
the ventilation system, temporarily
set the air intake control to the
recirculated air position. Be sure to
return the control to the fresh air
position when the irritation has
passed to keep fresh air in the
vehicle. This will help keep the driv-
er alert and comfortable.
To prevent interior fog on the wind- shield, set the air intake control to
the fresh air position and fan speed
to the desired position, turn on the
air conditioning system, and adjust
the temperature control to desired
temperature.

Engine Oil PressureWarning 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 details,
refer to “Engine Oil” in chapter 7) .
If the level is low, add oil as required.
If the warning light remains on
after adding oil or if oil is not avail-
able, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer as
soon as possible. 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 while 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 warning light stays on after the
engine is started, turn the
engine off immediately. In this
case, we recommend that you
have the vehicle inspected by
an authorized HYUNDAI dealer.
Low Fuel LevelWarning 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” can cause the
engine to misfire and damage the
catalytic converter (if equipped).

Driving your vehicleCarbon 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, we recommend that 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 tailgate 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.

If you believe your brakes may bewet, apply them lightly while driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increas-
es as the depth of tire tread
decreases, refer to "Tire Tread" in
chapter 7.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Highway driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engineoil
Driving at higher speeds on the high-
way consumes more fuel and is less
efficient than driving at a slower,
more moderate speed. Maintain a
moderate speed in order to conserve
fuel when driving on the highway.
Be sure to check both the engine
coolant level and the engine oil
before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

Driving your vehicle
Check battery and cables
The winter temperature increases
the battery consumption. Inspect
the battery and cables, as speci-
fied in the chapter 7. 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. For
further information, refer to the chap-
ter 8. When you are not sure about a
type of winter weight oil, consult an
authorized HYUNDAI dealer. Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in the chapter 7.
If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
frozen, spray approved de-icing fluid
or glycerin into key holes. When a
lock opening is already covered with
ice, spray approved de-icing fluid
over the ice to remove it. When an
internal part of a lock freezes, try to
thaw it with a heated key. Carefully
use the heated key to avoid an injury. Use approved window washer
anti-freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorized
HYUNDAI dealer, and so are the
most vehicle accessory outlets. Do
not use engine coolant or other types
of anti-freeze solution to prevent any
damage to the vehicle paint.
