Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components ofthe fuel system.
Petrols for cleaner air
To help contribute to cleaner air,
HYUNDAI recommends that you usegood quality petrols treated with deter-
gent additives such as TOP TIER
Detergent Petrol, which help prevent
deposit formation in the engine. These
petrols will help the engine run cleaner
and enhance performance of theEmission Control System.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
Observe all regulations regarding reg-
istration and insurance.
Determine that acceptable fuel is avail- able. No special run-in period is needed. By
following a few simple precautions for the
first 1,000 km (600 miles) you may add to
the performance, economy and life of
your vehicle.
Do not race the engine.
Whilst 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 needed to
properly run-in the engine.
Avoid hard stops, except in emergen- cies, to allow the brakes to seat prop-
erly.
Don't let the engine idle longer than 3 minutes at one time.
Don't tow a trailer during the first 2,000 km (1,200 miles) of operation.
CAUTION
Hyundai Warranty Policy will not
cover damage to the fuel systemand performance problems that arecaused by the use of methanol or
fuels containing methanol.

Features of your vehicle
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
Supplemental Restraint System (SRS) is
not working properly. If the SRS air bag
warning light does not come on, or
continuously 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 whilst
driving, have the SRS inspected by an
authorised HYUNDAI dealer.
Anti-lock brake system
(ABS) warning light (if equipped)
This light illuminates if the ignition switch
is turned 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 whilst driving, or does not
come on when the ignition switch is
turned to the ON position, this indicates
that there may be a malfunction 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 with-
out the assistance of the anti-lock brakesystem. Electronic brake
force distribution
(EBD) system
warning light
If two warning lights illuminate at the
same time whilst driving, your vehicle
may have a malfunction with the ABSand EBD system.
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.
✽✽
NOTICE
If the ABS warning light or EBD warn-
ing light is on and stays on, the
speedometer or odometer/tripmeter
may not work. In this case, have your
vehicle checked by an authorised
HYUNDAI dealer as soon as possible.
WARNING
If the both ABS and brake warning
lights are on and stay on, your vehi-
cle’s brake system will not work
normally during sudden braking. In
this case, avoid high speed driving
and abrupt braking. Have your vehi-
cle checked by an authorised
HYUNDAI dealer as soon as possi-
ble.

Features of your vehicle
Parking brake & brakefluid warning light
Parking brake warning
This light is illuminated when the parking
brake is applied with the ignition switch in
the START or ON position. The warning
light should go off when the parking
brake is released whilst the engine is
running. Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are found, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any autho-
rised HYUNDAI dealer for a brake sys-
tem inspection and necessary repairs.
Your vehicle is equipped with dual-diago-
nal braking systems. This means you still
have braking on two wheels even if one
of the dual systems should fail. With only
one of the dual systems working, more
than normal pedal travel and greaterpedal pressure are required to stop the
car. Also, the car will not stop in as short
a distance with only a portion of the
brake system working. If the brakes fail
whilst you are driving, shift to a lower
gear for additional engine braking and
stop the car as soon as it is safe to do so.
CAUTION
If the oil pressure warning light stays on whilst the engine is run-
ning, serious engine damage mayresult. The oil pressure warninglight comes on whenever there is insufficient oil pressure. In normal
operation, it should come on whenthe ignition switch is turned on,then go out when the engine is
started. If the oil pressure warninglight stays on whilst the engine isrunning, there is a serious malfunc-tion.
If this happens, stop the car assoon as it is safe to do so, turn off the engine and check the oil level. Ifthe oil level is low, fill the engine oilto the proper level and start the
engine again. If the light stays onwith the engine running, turn theengine off immediately. In any instance where the oil light stays on
when the engine is running, theengine should be checked by an authorised HYUNDAI dealer beforethe car is driven again.

Non-operational conditions of rear parking assist system
The rear parking assist system may
not operate properly when:
1. Moisture is frozen to the sensor. (It will
operate normally when the moisture has been cleared.)
2. The sensor is covered with foreign matter, such as snow or water, or the
sensor cover is blocked. (It will operate
normally when the material is removed
or the sensor is no longer blocked.)
3. Driving on uneven road surfaces (unpaved roads, gravel, bumps, gradi-ent).
4. Objects generating excessive noise (vehicle horns, loud motorcycle
engines, or truck air brakes) are within
range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the sensor.
7. The sensor is covered with snow.
8. Trailer towing The detecting range may decrease when:
1. The sensor is stained with foreign mat-
ter such as snow or water. (The sens-
ing range will return to normal when
removed.)
2. Outside air temperature is extremely hot or cold.
The following objects may not be rec-
ognized by the sensor:
1. Sharp or slim objects such as ropes, chains or small poles.
2. Objects which tend to absorb the sen- sor frequency such as clothes, spongy
material or snow.
3. Undetectable objects smaller than 1 m (40 in.) in height and narrower than 14
cm (6 in.) in diameter. Rear parking assist system pre- cautions
The rear parking assist system may
not sound sequentially depending on the speed and shapes of the objectsdetected.
The rear parking assist system may malfunction if the vehicle bumperheight or sensor installation has been
modified or damaged. Any non-factory
installed equipment or accessories
may also interfere with the sensor per-
formance.
The sensor may not recognize objects less than 40 cm (15 in.) from the sen-
sor, or it may sense an incorrect dis-
tance. Use caution.
When the sensor is frozen or stained with snow, dirt, or water, the sensor
may be inoperative until the stains are
removed using a soft cloth.
Do not push, scratch or strike the sen- sor. Sensor damage could occur.

Press the engine start/stop button whilst
it is in the ACC position without depress-
ing the brake pedal.
The warning lights can be checked
before the engine is started. Do not leave
the button in the ON position if the engine
is not running to prevent the battery fromdischarging.
START
To start the engine, press the brake
pedal and press the engine start/stop
button with the shift lever in the P (Park)
or the N (Neutral) position. For your safe-
ty, start the engine with the shift lever in
the P (Park) position.
✽✽
NOTICE
 If you press the engine start/stop but- ton without depressing the brake
pedal, the engine does not start and
the engine start/stop button changes
as follow :
OFF →
→
ACC →→
ON →→
OFF
 If you leave the engine start/stop but-
ton in the ACC or the ON position for
a long time, the battery may be dis-
charged.
WARNING
Never press the engine start/stop button whilst the vehicle is in
motion. This would result in theengine turning off and loss of
power assist for the steering and
brakes, which may lead to loss of
directional control and braking
function, which could cause anaccident.
The anti-theft steering column lock is not a substitute for the
parking brake. Before leaving the
driver’s seat, always make sure
the shift lever is engaged in P
(Park),set the parking brake fully
and shut the engine off.
Unexpected and sudden vehicle
movement may occur if theseprecautions are not taken.
(Continued)
(Continued)
Never reach for the enginestart/stop button, or any other
controls through the steering
wheel whilst the vehicle is in
motion. The presence of yourhand or arm in this area could
cause a loss of vehicle control,
an accident and serious bodily
injury or death.
Do not place any movable objects around the driver’s seat as they
may move whilst driving, inter-
fere with the driver and lead to anaccident.

Driving your vehicle
Downshifting
When you must slow down in heavy traf-
fic or whilst driving up steep hills, down-
shift before the engine starts to labour.
Downshifting reduces the chance of
stalling and gives better acceleration
when you again need to increase your
speed. When the vehicle is travelling
down steep hills, downshifting helps
maintain safe speed and prolongs brake
life.Good driving practices
Never take the vehicle out of gear and
coast down a hill. This is extremely
hazardous. Always leave the vehicle in
gear.
Don't "ride" the brakes. This can cause them to overheat and malfunction.
Instead, when you are driving down a
long hill, shift to a lower gear. When
you do this, engine braking will help
slow down the vehicle.
Slow down before shifting to a lower gear. This will help avoid over-revving
the engine, which can cause damage.
Slow down when you encounter cross winds. This gives you much better con-
trol of your vehicle.
Be sure the vehicle is completely stopped before you attempt to shift into
reverse. The transaxle can be dam-
aged if you do not. To shift into reverse,
depress the clutch, move the shift lever
to neutral, wait three seconds, then
shift to the reverse position.
Exercise extreme caution when driving on a slippery surface. Be especially
careful when braking, accelerating or
shifting gears. On a slippery surface,
an abrupt change in vehicle speed can
cause the drive wheels to lose traction
and the vehicle can lose control.WARNING
Always buckle-up! In a collision, an unbelted occupant is signifi-
cantly more likely to be seriously
injured or killed than a properlybelted occupant.
Avoid high speeds when corner- ing or turning.
Do not make quick steering wheel movements, such as sharp
lane changes or fast, sharp turns.
The risk of rollover is greatly increased if you lose control of
your vehicle at highway speeds.
Loss of control often occurs if two or more wheels drop off the
roadway and the driver over-
steers to reenter the roadway.
In the event your vehicle leaves the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
Never exceed posted speed lim- its.

515
Driving your vehicle
For smooth operation, depress the brakepedal when shifting from N (Neutral) to aforward or reverse gear.Transaxle ranges
The indicator in the instrument cluster
displays the shift lever position when the
ignition switch is in the ON position.
P (Park)
Always come to a complete stop before
shifting into P (Park). This position locks
the transaxle and prevents the drivewheels from rotating.
WARNING - Automatic
transaxle
Always check the surrounding areas near your vehicle for peo-
ple, especially children, beforeshifting a car into D (Drive) or R
(Reverse).
Before leaving the driver’s seat, always make sure the shift lever
is in the P (Park) position; then
set the parking brake fully and
shut the engine off. Unexpected
and sudden vehicle movementcan occur if these precautions
are not followed in the order iden-tified.
CAUTION
To avoid damage to your
transaxle, do not accelerate the
engine in R (Reverse) or any for-ward gear position with thebrakes on.
When stopped on an incline, do not hold the vehicle stationarywith engine power. Use the serv-ice brake or the parking brake.
Do not shift from N (Neutral) or P (Park) into D (Drive), or R
(Reverse) when the engine isabove idle speed.
WARNING
Shifting into P (Park) whilst the vehicle is in motion will cause the
drive wheels to lock which will
cause you to lose control of the
vehicle.
Do not use the P (Park) position in place of the parking brake.
Always make sure the shift lever
is latched in the P (Park) position
and set the parking brake fully.
Never leave a child unattended in a vehicle.
