fuel additives HYUNDAI ELANTRA SE 2017 Owners Manual

F8
Introduction
"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15
percent gasoline, and is manufac-
tured exclusively for use in Flexible
Fuel Vehicles. "E85" is not compati-
ble with your vehicle. Use of "E85"
may result in poor engine perform-
ance and damage to your vehicle's
engine and fuel system. HYUNDAI
recommends that customers do not
use fuel with an ethanol content
exceeding 15 percent.
To prevent damage to your vehicle’s
engine and fuel system:
Never use gasohol which con- tains methanol.
Never use gasohol containing more than 15% ethanol.
Never use leaded fuel or leaded gasohol.
Never use "E85" fuel.
Your New Vehicle Limited
Warranty does not cover damage
to the fuel system or any perform-
ance problems caused by the use
of "E85" fuel.
Using Fuel Additives (except Detergent Fuel Additives)
Using fuel additives such as:
- Silicone fuel additive
- Ferrocene (iron-based) fuel additive
- Other metallic-based fuel additives
may result in cylinder misfire, poor
acceleration, engine stalling, dam-
age to the catalyst, or abnormal cor-
rosion, and may cause damage to
the engine resulting in a reduction in
the overall life of the powertrain.
- The Malfunction Indicator Lamp
(MIL) may illuminate.
Damage to the fuel system or per-
formance problem caused by the
use of these fuels or fuel additives
may not be covered by your New
Vehicle Limited Warranty.
Gasoline containing MMT
Some gasoline contains harmful
manganese-based fuel additives
such as
MMT (Methylcyclopentadienyl
Manganese Tricarbonyl
).
HYUNDAI does not recommend the
use of gasoline containing MMT.
This type of fuel can reduce vehicle
performance and affect your emis-
sion control system.
The malfunction indicator lamp on
the cluster may come on.
Detergent Fuel Additives
HYUNDAI recommends that you use
good quality gasolines treated with
detergent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine
run cleaner and enhance performance
of the Emission Control System. For
more information on TOP TIER
Detergent Gasoline, please go to the
website (www
.toptiergas.com).

Introduction
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, deter-
gent-based fuel additives that you
can purchase separately may be
added to the gasoline. If TOP TIER
Detergent Gasoline is not available,
one bottle of additive added to the
fuel tank at every 7,500 miles or 12
months is recommended.
Additives are available from your
authorized HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
Observe all regulations regarding registration and insurance.
Determine that acceptable fuel is available. This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or perform-
ance problems resulting from any
modification may not be covered
under warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices. By following a few simple precautions
for the first 600 miles (1,000 km) you
may add to the performance, econo-
my and life of your vehicle.
Do not race the engine.
While driving, keep your engine
speed (rpm, or revolutions per
minute) between 2,000 rpm and
4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or
slow. Varying engine speed is need-
ed to properly break-in the engine.
Avoid hard stops, except in emer- gencies, to allow the brakes to seat
properly.
