Unlead
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.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimise exhaust emis-
sions and spark plug fouling.
Petrol containing alcohol andmethanol
Ethanol [E-10], a mixture of petrol and
ethanol (also known as grain alcohol),and petrol or ethanol containing
methanol (also known as wood alcohol)
are being marketed along with or insteadof leaded or unleaded petrol. Do not use ethanol containing more than 10% ethanol, and do not use petrol or
ethanol containing any methanol. Either
of these fuels may cause drivability prob-lems and damage to the fuel system.
Discontinue using ethanol of any kind if
drivability problems occur.
Vehicle damage or driveability problems
may not be covered by the manufactur-
er’s warranty if they result from the useof:
1. Ethanol containing more than 10%.
2. Petrol or ethanol containing methanol.
3. Leaded fuel or leaded ethanol.
FUEL REQUIREMENTS
CAUTION

an authorised Hyundai dealer fordetails.)
CAUTION
Do not "top off" after the nozzle
automatically shuts off whenrefuelling.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci- dent.

removed from the bonnet open-
ing. Closing the bonnet with anobstruction present in the bonnet
opening may result in property
damage or severe personal
injury.

(Continued)Use only portable plastic fuel
containers designed to carry and
store petrol.
Do not use mobile phones while refuelling. Electric current and/or
electronic interference from
mobile phones can potentially
ignite fuel vapours causing a fire.
When refuelling, always shut the engine off. Sparks produced byelectrical components related tothe engine can ignite fuel
vapours causing a fire. Once
refuelling is complete, check tomake sure the filler cap and filler
door are securely closed, before
starting the engine.
DO NOT use matches or a lighter and DO NOT SMOKE or leave a lit
cigarette in your vehicle while at
a petrol station especially during

vehicle, and immediately contact
the manager of the petrol stationand then contact the local fire
department. Follow any safety
instructions they provide.
CAUTION

specified for your vehicle. Anincorrect fuel filler cap can resultin a serious malfunction of the fuel system or emission control
system.

STEERING WHEEL
Electronic power steering
Power steering uses the motor to assist
you in steering the vehicle. If the engine
is off or if the power steering system
becomes inoperative, the vehicle may
still be steered, but it will require
increased steering effort.
The motor driven power steering is con-
trolled by power steering control unit
which sense the steering wheel torque,
steering wheel position and vehicle
speed to command the motor.
The steering wheel becomes heavier as
the vehicle’s speed increases and
becomes lighter as the vehicle’s speed
decreases for the better control of the
steering wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorised Hyundai
dealer.
✽✽ NOTICE
The following symptoms may be
occurred during normal vehicle opera-
tion and if there is no illumination ofEPS warning light, it is not malfunction
of EPS system. After turning the igni-tion switch on, the steering wheel
becomes heavier while it performs EPS
system diagnostics for a few seconds,
then it returns to be normal steering
condition. The click sound of EPS relay
may occur after turning the ignition
switch on or off, this is normal opera-
tion. When it is steered in the stop posi-
tion or low driving speed, motor noise
may occur again, this is normal opera-tion.Tilt steering
A tilt steering wheel allows you to adjust
the steering wheel before you drive. You
can also raise it to the highest level to
give your legs more room when you exit
and enter the vehicle.
The steering wheel should be positioned
so that it is comfortable for you to drive,
while permitting you to see the instru-
ment panel warning lights and gauges.

Warnings and indicators
All warning lights are checked by turning
the ignition switch ON (do not start the
engine). Any light that does not illuminate
should be checked by an authorised
Hyundai dealer.
After starting the engine, check to make
sure that all warning lights are off. If anyare still on, this indicates a situation that
needs attention. When releasing the
hand brake, the brake system warning
light should go off. The fuel warning light
will stay on if the fuel level is low.
Air bag warning light (if equipped)
This warning light will illuminate for
approximately 6 seconds each time you
turn the ignition switch to the ON posi-tion. This light also comes on when the SRS
is not working properly. If the AIRBAG
warning light does not come on, or con-
tinuously remains on after operating for
about 6 seconds when you turned the
ignition switch to the ON position or start-
ed the engine, or if it comes on while
driving, have the SRS inspected by an
authorised Hyundai dealer.

is turned to ON and goes off in approxi-
mately 3 seconds if the system is operat-
ing normally.
If the ABS warning light remains on,
comes on while driving, or does not
come on when the ignition switch is
turned to the ON position, this indicates
that there may be a problem with the
ABS.
If this occurs, have your vehicle checked
by an authorised Hyundai dealer as soon
as possible. The normal braking system
will still be operational, but without the
assistance of the anti-lock brake system. Electronic brake force distri-bution (EBD) system warninglight

driving, your vehicle has a
problem with ABS and EBDsystem.
In this case, your ABS and regular brake
system may not work normally. Have the
vehicle checked by an authorised
Hyundai dealer as soon as possible.
