Driving your vehicle
R (Reverse)
Use this position to drive the vehicle
backward.N (Neutral)
The wheels and transaxle are not
engaged. The vehicle will roll freely even
on the slightest incline unless the parking
brake or service brakes are applied.
D (Drive)
This is the normal forward driving posi-
tion. The transaxle will automatically shift
through a 6-gear sequence, providing the
best fuel economy and power.
For extra power when passing another
vehicle or climbing grades, depress the
accelerator fully, at which time the
transaxle will automatically downshift to
the lower gear.
✽✽
NOTICE
Always come to a complete stop before
shifting into D (Drive).
CAUTION
The transaxle may be damaged if you shift into P (Park) whilst the
vehicle is in motion.
CAUTION
Always come to a complete stopbefore shifting into or out of R (Reverse); you may damage thetransaxle if you shift into R (Reverse) whilst the vehicle is in
motion, except as explained in“Rocking the vehicle” in this sec- tion.

Ignition key interlock system
(if equipped)
The ignition key cannot be removed
unless the shift lever is in the P (Park)
position. If the ignition switch is in any
other position, the key cannot be
removed. Good driving practices
Never move the shift lever from P
(Park) or N (Neutral) to any other posi-
tion with the accelerator pedaldepressed.
Never move the shift lever into P (Park) when the vehicle is in motion.
Be sure the car is completely stopped before you attempt to shift into R
(Reverse) or D (Drive).
Never take the car out of gear and coast down a hill. This may be
extremely hazardous. Always leave the
car in gear when moving.
Do not "ride" the brakes. This can cause them to overheat and malfunc-
tion. Instead, when you are driving
down a long hill, slow down and shift to
a lower gear. When you do this, engine
braking will help slow the car.
Slow down before shifting to a lower gear. Otherwise, the lower gear maynot be engaged. Always use the parking brake. Do not
depend on placing the transaxle in P
(Park) to keep the car from moving.
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 to go out of control.
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the accelera-tor pedal.

Driving your vehicle
Moving up a steep grade from a stand-ing start
To move up a steep grade from a stand-
ing start, depress the brake pedal, shift
the shift lever to D (Drive). Select the
appropriate gear depending on load
weight and steepness of the grade, and
release the parking brake. Depress the
accelerator gradually whilst releasing the
service brakes.
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle free
by moving it forward and backward.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle. During the rocking
operation the vehicle may suddenly
move forward of backward as it
becomes unstuck, causing injury
or damage to nearby people orobjects.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.

Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces. BRAKE SYSTEM
WARNING
- Brakes
Do not drive with your foot rest- ing on the brake pedal. This will create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increasedstopping distances.
When descending a long or steep hill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brakeapplication will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may impair the vehi- cle’s ability to safely slow down;
the vehicle may also pull to oneside when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
whilst maintaining a safe forward
speed until brake performancereturns to normal.
(Continued)(Continued)
Always, confirm the position ofthe brake and accelerator pedal
before driving. If you don't checkthe position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It maycause a serious accident.

Driving your vehicle
In the event of brake failure
If service brakes fail to operate whilst the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
Disc brakes wear indicator
Your vehicle has disc brakes.
When your brake pads are worn and new
pads are required, you will hear a high-
pitched warning sound from your front
brakes or rear brakes. You may hear this
sound come and go or it may occur
whenever you depress the brake pedal.
Please remember that some driving con-
ditions or climates may cause a brake
squeal when you first apply (or lightly
apply) the brakes. This is normal and
does not indicate a problem with your
brakes.Parking brake
Applying the parking brake
Foot type
To engage the parking brake, first apply
the foot brake and then depress the park-
ing brake pedal down as far as possible.
WARNING- Parking brake
Applying the parking brake whilst
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you mustuse the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.
WARNING - Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking
performance, which could lead to aserious accident.
CAUTION
To avoid costly brake repairs, do not continue to drive with wornbrake pads.
Always replace brake pads as complete front or rear axle sets.

Anti-lock brake system (ABS) (if equipped)
*: Some countries use the term ESC(Electronic stability control) instead of
ESP. Please refer to the term your
country use. The ABS continuously senses the speed
of the wheels. If the wheels are going to
lock, the ABS system repeatedly modu-
lates the hydraulic brake pressure to the
wheels.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ABS is active.
In order to obtain the maximum benefit
from your ABS in an emergency situa-
tion, do not attempt to modulate your
brake pressure and do not try to pump
your brakes. Press your brake pedal as
hard as possible or as hard as the situa-
tion warrants and allow the ABS to con-
trol the force being delivered to the
brakes.(Continued)
On roads where the road surface
is pitted or has different surface height.
The safety features of an ABS (or
ESP/ESC*) equipped vehicle
should not be tested by high speed
driving or cornering. This could
endanger the safety of yourself or
others.
WARNING
ABS (or ESP/ESC*) will not prevent
accidents due to improper or dan-
gerous driving manoeuvres. Even
though vehicle control is improved
during emergency braking, always
maintain a safe distance between
you and objects ahead. Vehicle
speeds should always be reduced
during extreme road conditions.
The braking distance for cars
equipped with an anti-lock braking
system (or Electronic Stability
Program system/Electronic
Stability Control*) may be longer
than for those without it in the fol-
lowing road conditions.
During these conditions the vehicle should be driven at reducedspeeds:
Rough, gravel or snow-covered roads.
With tyre chains installed. (Continued)

Driving your vehicle
✽✽NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the anti-lock brake system
is functioning properly.
Even with the anti-lock brake system, your vehicle still requires sufficient
stopping distance. Always maintain a
safe distance from the vehicle in front
of you.
Always slow down when cornering. The anti-lock brake system cannot pre-
vent accidents resulting from exces-
sive speeds.
On loose or uneven road surfaces, operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.
✽✽ NOTICE
When you jump start your vehicle
because of a drained battery, the engine
may not run as smoothly and the ABS
warning light may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning.
 Do not pump your brakes!
 Have the battery recharged before driving the vehicle.
W-78
CAUTION
If the ABS warning light is on and
stays on, you may have a problemwith the ABS. In this case, howev-er, your regular brakes will work normally.
The ABS warning light will stay on for approximately 3 seconds afterthe ignition switch is ON. Duringthat time, the ABS will go throughself-diagnosis and the light will go off if everything is normal. If thelight stays on, you may have aproblem with your ABS. Contactan authorised HYUNDAI dealer assoon as possible.
CAUTION
When you drive on a road having poor traction, such as an icy road,
and operate your brakes continu- ously, the ABS will be active con-tinuously and the ABS warninglight may illuminate. Pull your car
over to a safe place and stop theengine.
Restart the engine. If the ABS warning light is off, then your
ABS system is normal. Otherwise, you may have a prob-lem with the ABS. Contact an authorised HYUNDAI dealer as
soon as possible.

Electronic stability program (ESP) (if equipped)
The Electronic Stability Program (ESP)
system is designed to stabilize the vehicle
during cornering manoeuvres. ESP
checks where you are steering and where
the vehicle is actually going.
ESP applies the brakes at individual
wheels and intervenes in the engine
management system to stabilize the
vehicle. The Electronic Stability Program (ESP)system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESP will be effective in
preventing a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESP is active.
✽✽
NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Program System is functioning proper-
ly.
OYF059015R
WARNING
Never drive too fast for the road
conditions or too quickly when cor-
nering. Electronic stability program
(ESP) will not prevent accidents.
Excessive speed in turns, abrupt
manoeuvres and hydroplaning onwet surfaces can still result in seri-
ous accidents. Only a safe and
attentive driver can prevent acci-
dents by avoiding manoeuvres that
cause the vehicle to lose traction.
Even with ESP installed, always fol-
low all the normal precautions for
driving - including driving at safe
speeds for the conditions.
