For smooth operation, depress the brake
pedal 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.

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
Hand type
To release the parking brake, first apply
the foot brake and pull up the parking
brake lever slightly. Secondly depress the
release button (1) and lower the parking
brake lever (2) whilst holding the button.If the parking brake does not release or
does not release all the way, have the
system checked by an authorised
HYUNDAI dealer.
Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will be illuminated
when the parking brake is applied with
the ignition switch in the START or ONposition.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on
after the parking brake is released whilst
engine is running, there may be a mal-
function in the brake system. Immediate
attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution whilst operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop.

WARNING
To prevent unintentional move- ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parkingbrake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transaxle
equipped vehicles and in P (Park)
for automatic transaxle equipped
vehicles.
Never allow anyone who is unfa- miliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants orpedestrians.

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.

Hill-start assist control (HAC) (if equipped)
A vehicle has the tendency to slip back
on a steep hill when it starts to go after
stopping. The Hill-start Assist Control
(HAC) prevents the vehicle from slipping
back by operating the brakes automati-
cally for about 2 seconds. The brakes are
released when the accelerator pedal is
depressed or after about 2 seconds.
✽✽
NOTICE
 The HAC does not operate when the transaxle shift lever is in the P (Park)
or N (Neutral) position.
 The HAC activates even though the ESP(or ESC) is off but it does not acti-
vate when the ESP(or ESC) has mal-
functioned.
Good braking practices After parking the vehicle, check to be
sure the parking brake is not engaged
and that the parking brake indicator
light is out before driving away.
Driving through water may get the brakes wet. They can also get wet
when the car is washed. Wet brakes
can be dangerous! Your car will not
stop as quickly if the brakes are wet.
Wet brakes may cause the car to pull
to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns to
normal, taking care to keep the car
under control at all times. If the braking
action does not return to normal, stop
as soon as it is safe to do so and call
an authorised HYUNDAI dealer for
assistance.
Don't coast down hills with the car out of gear. This is extremely hazardous.
Keep the car in gear at all times, use
the brakes to slow down, then shift to a
lower gear so that engine braking will
help you maintain a safe speed.
WARNING
The HAC is activated only for about
2 seconds, so when the vehicle is
starting off always depress theaccelerator pedal.
WARNING
Whenever leaving vehicle or parking, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the park position. Vehicles
not fully engaged in park with the
parking brake set are at risk for
moving inadvertently and injur-
ing yourself or others.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the car whichcan injure occupants or pedestri-ans.

Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
kilometers (miles) you can get from a litre
(gallon) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-
ate rate. Don't make "kangaroo" starts or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-tion. Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
Take care of your tyres. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tyre
wear. Check the tyre pressures at leastonce a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting kerbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tyre wear and may
also result in other problems as well as
greater fuel consumption. Keep your car in good condition. For
better fuel economy and reduced
maintenance costs, maintain your carin accordance with the maintenance
schedule in section 7. If you drive your
car in severe conditions, more frequentmaintenance is required (see section 7
for details).
Keep your car clean. For maximum service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel con-
sumption and also contribute to corro-sion.
Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel
economy.
Don't let the engine idle longer than necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.
