Introduction
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-
lems and damage to the fuel system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufactur-
er’s warranty if they result from the use
of:
1. Gasohol containing more than 10%
ethanol.
2. Gasoline or gasohol containing
methanol.
3. Leaded fuel or leaded gasohol.
Leaded (if equipped)
For some countries, your vehicle is
designed to use leaded gasoline. When
you are going to use leaded gasoline,
ask to an authorized HYUNDAI dealer
whether leaded gasoline in your vehicle
is available or not.
Octane Rating of leaded gasoline is
same with unleaded one.
WARNING
• Do not "top off" after the nozzle
automatically shuts off when
refueling.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and will
damage the engine control sys-
tem’s oxygen sensor and affect
emission control.
Never add any fuel system cleaning
agents to the fuel tank other than
what has been specified. (Consult
an authorized HYUNDAI dealer for
details.)
CAUTION
Never use gasohol which contains
methanol. Discontinue use of any
gasohol product which impairs dri-
vability.

The purpose of the pre-safe seat belt is
to prevent passengers from getting hurt
by tightening the seat belt right before a

- Emergency braking situation occurs
- Losing control of the vehicle
- The passenger leans to one side
• The seat belt vibrates when:
- The vehicle senses a object too near
the vehicle
- The Lane Departure Warning System
(if equipped) detects the vehicle has
moved out of its lane
Other functions are tightening a loose
seat belt after vehicle speed is over 40
km/h. and winding a loose seat belt after
unfastening the seat belt.

belt deployment.
The SRS air bag warning light " " on
the instrument panel will illuminate for
about 6 seconds after the engine
start/stop button is turned to the ON posi-
tion, after which the SRS air bag warning
