WARNING
- Ignition key
Leaving children unattended in a
vehicle with the ignition key is dan-
gerous even if the key is not in the
ignition. Children copy adults and
they could place the key in the igni-
tion. The ignition key would enable
children to operate power windows
or other controls, or even make the
vehicle move, which could result in
serious bodily injury or even death.
Never leave the keys in your vehicle
with unsupervised children.

WARNING
Use only HYUNDAI original parts
for the ignition key in your vehicle.
If an aftermarket key is used, the
ignition switch may not return to
ON after START. If this happens,
the starter will continue to operate
causing damage to the starter
motor and possible fire due to
excessive current in the wiring.

D010300CUN-EA Immobiliser system
Your vehicle is equipped with an elec- tronic engine immobiliser system to
reduce the risk of unauthorised vehicle
use.
Your immobiliser system is comprised of
a small transponder in the ignition key
and electronic devices inside the vehicle.
With the immobiliser system, whenever
you insert your ignition key into the igni-
tion switch and turn it to ON, it checks
and determines and verifies if the ignition
key is valid or not.
If the key is determined to be valid, the
engine will start.
If the key is determined to be invalid, the
engine will not start.
To deactivate the immobiliser sys-tem:
Insert the ignition key into the key cylin-
der and turn it to the ON position.
To activate the immobiliser system:
Turn the ignition key to the OFF position.
The immobiliser system activates auto-
matically. Without a valid ignition key for
your vehicle, the engine will not start.
✽✽ NOTICE
When starting the engine, do not use the
key with other immobiliser keys around.Otherwise the engine may not start or
may stop soon after it starts. Keep eachkey separately not to have any malfunc-
tion after you receive your new vehicle.
✽
✽ NOTICE
If you need additional keys or lose your keys, consult an authorised HYUNDAI
dealer.
OHD046100
CAUTION
Do not put metal accessories near the ignition switch.
The engine may not start as themetal accessories may interrupt the
transponder signal from normally transmitting.

WARNING
- Refuelling
If pressurized fuel sprays out, it can cover your clothes or skin
and thus subject you to the risk
of fire and burns. Always remove
the fuel cap carefully and slowly.
If the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
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.

WARNING - Refuelling
dangers
Automotive fuels are flammable
materials. When refuelling, please
note the following guidelines care-
fully. Failure to follow these guide-
lines may result in severe personal
injury, severe burns or death by fire
or explosion.
Read and follow all warning at the petrol station facility.
Before refuelling note the loca- tion of the Emergency Fuel Shut-
Off, if available, at the petrol sta-
tion facility.
Before touching the fuel nozzle, you should eliminate potentially
dangerous static electricity dis-
charge by touching another metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other petrol
source.
(Continued)(Continued)
Do not get back into a vehicleonce you have begun refuelling
since you can generate static
electricity by touching, rubbing
or sliding against any item or fab-
ric (polyester, satin, nylon, etc.)
capable of producing static elec-
tricity. Static electricity discharge
can ignite fuel vapours resulting
in rapid burning. If you must re-
enter the vehicle, you should
once again eliminate potentially
dangerous static electricity dis-
charge by touching a metal part
of the vehicle, away from the fuel
filler neck, nozzle or other petrol
source.
When using a portable fuel con- tainer be sure to place the con-
tainer on the ground prior to refu-
elling. Static electricity discharge
from the container can ignite fuel
vapours causing a fire. Once
refuelling has begun, contact
with the vehicle should be main-tained until the filling is com-
plete.
(Continued)(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
refuelling. Automotive fuel is
highly flammable and can, when
ignited, result in fire.

Power steering
Power steering uses energy from the
engine to assist you in steering the vehi-
cle. 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.
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
If the power steering drive belt breaks
or if the power steering pump malfunc-
tions, the steering effort will greatly
increase. ✽
✽
NOTICE
If the vehicle is parked for extended
periods outside in cold weather (below -
10°C/14°F), the power steering may
require increased effort when the engine
is first started. This is caused by
increased fluid viscosity due to the cold
weather and does not indicate a mal-function.
When this happens, increase the engine
RPM by depressing accelerator until the
RPM reaches 1,500 rpm then release or
let the engine idle for two or three min-utes to warm up the fluid. D130300ANF Tilt steering
A tilt steering wheel allows you to adjust
the steering wheel before you drive. You
can also raise it to give your legs more
room when you exit and enter the vehicle(if equipped).
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.
STEERING WHEEL
CAUTION
Never hold the steering wheel
against a stop (extreme right or left turn) for more than 5 seconds withthe engine running. Holding thesteering wheel for more than 5 sec-
onds in either position may causedamage to the power steeringpump.
WARNING
Never adjust the angle and height of steering wheel while driving.
You may lose your steering con-
trol and cause severe personal
injury or accidents.
After adjusting, push the steering wheel both up and down to be
certain it is locked in position.
