2017 Hyundai Elantra catalytic converter

F6
Introduction
NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage.
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you use unleaded
gasoline which has an octane rating of
RON (Research Octane Number) 95 /
AKI (Anti Knock Index) 91 or higher.
You may use unleaded gasoline with
an octane rating of RON 91-94 / AKI
87-90 but it may result in slight per-
formance reduction of the vehicle. (Do
not use methanol blended fuels)
Except Europe
Your new vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 / AKI (Anti-Knock Index)
87 or higher. (Do not use methanol
blended fuels)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.
NOTICE
•Do not "top off" after the noz-
zle automatically shuts off
when refueling.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental
to the catalytic converter and
will damage the engine control
system’s oxygen sensor and
affect emission control.
Never add any fuel system
cleaning agents to the fuel tank
other than what has been speci-
fied (We recommend that you
consult an authorized HYUNDAI
dealer for details.)

Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
• The fuel tank capacity is given in
chapter 8.
• The fuel gauge is supplemented by a
low fuel warning light, which will
illuminate when the fuel tank is
nearly empty.
• On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier
than usual due to the movement of
fuel in the tank.Avoid driving with a extremely low
fuel level. Running out of fuel
could cause the engine to misfire
damaging the catalytic converter.
NOTICE
i
Never remove the radiator cap or
reservoir cap when the engine is
hot. The engine coolant is under
pressure and could severe
burns. Wait until the engine is
cool before adding coolant to the
reservoir.
WARNING
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addi-
tional fuel as soon as possible
after the warning light comes
on or when the gauge indicator
comes close to the "0 or E
(Empty)" level.

Engine Oil Pressure
Warning Light
This warning light illuminates:
• Once you turn the ignition switch or
the Engine Start/Stop button to the
ON position.
- It remains on until the engine is
started.
• 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 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).

Maintenance
Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void
your warranties.
Diesel particulate filter (DPF)
(if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot in the
exhaust gas.
The DPF system automatically burns
(or oxidizes) the accumulated soot in
accordance with the driving situa-
tions, unlike a disposable air filter.
In other words, the accumulated soot
is automatically purged out by the
engine control system and by the high
exhaust-gas temperature at normal/
high driving speeds.
However, when the vehicle is continu-
ally driven at repeated short distance
or driven at low speed for a long time,
the accumulated soot may not be
automatically removed because of low
exhaust gas temperature. In this case,
the accumulated soot is out of the
detection range, the soot oxidization
process does not occur, and the
Malfunction Indicator Lamp ( )
Illuminates.
•Use only UNLEADED FUEL
for gasoline engine.
•Do not operate the vehicle
when there are signs of
engine malfunction, such as
misfire or a noticeable loss of
performance.
•Do not misuse or abuse the
engine. Examples of misuse
are coasting with the engine
off and descending steep
grades in gear with the engine
off.
(Continued)
(Continued)
•Do not operate the engine at
high idle speed for extended
periods (5 minutes or more).
•Do not modify or tamper with
any part of the engine or
emission control system. All
inspections and adjustments
must be made by an author-
ized HYUNDAI dealer.
•Avoid driving with a very low
fuel level. If you run out of
gasoline, it could cause the
engine to misfire and result in
excessive loading of the cat-
alytic converter.
