Petrol engine
Unleaded
We recommend to use unleaded
petrol which has an octane rating of
RON(Research Octane Number) 91 /
AKI (Anti Knock Index) 87 or higher.
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.
CAUTION
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 a HYUNDAI authorised
repairer for details.)
WARNING
•
Do not "top off" after the noz-
zle automatically shuts off
when refuelling.
•
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
Introduction
Petrol containing alcohol and
methanol
Gasohol, a mixture of petrol and
ethanol (also known as grain alco-
hol), and petrol or gasohol containing
methanol (also known as wood alco-
hol) are being marketed along with or
instead of leaded or unleaded petrol.
Do not use gasohol containing more
than 10% ethanol, and do not use
petrol or gasohol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine control
system and emission control system.
Discontinue using gasohol of any
kind if drivability problems occur.
