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.

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.

To keep locks from freezing
To keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into
the key opening. If a lock is covered with
ice, squirt it with an approved de-icing
fluid to remove the ice. If the lock is
frozen internally, you may be able to thaw
it out by using a heated key. Handle the
heated key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the con-
tainer. Window washer anti-freeze is
available from an authorised HYUNDAI
dealer and most auto parts outlets. Donot use engine coolant or other types of
anti-freeze as these may damage thepaint finish.Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. If there is a risk the parking
brake may freeze, apply it only temporar-
ily whilst you put the shift lever in P (auto-
matic transaxle) or in first or reverse gear
(manual transaxle) and block the rear
wheels so the vehicle cannot roll. Then
release the parking brake.
Don't let ice and snow accumu- late underneath
Under some conditions, snow and ice
can build up under the fenders and inter-
fere with the steering. When driving in
severe winter conditions where this may
happen, you should periodically check
underneath the car to be sure the move-
ment of the front wheels and the steering
components is not obstructed.Carry emergency equipment
Depending on the severity of the weath-
er where you drive your car, you should
carry appropriate emergency equipment.
Some of the items you may want to carry
include tyre chains, tow straps or chains,
flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket,etc.

Turn signals when towing a trailer
When you tow a trailer, your vehicle has
to have a different turn signal flasher and
extra wiring. The green arrows on your
instrument panel will flash whenever you
signal a turn or lane change. Properly
connected, the trailer lights will also flash
to alert other drivers you’re about to turn,
change lanes, or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think drivers
behind you are seeing your signals
when, in fact, they are not. It’s important
to check occasionally to be sure the trail-
er bulbs are still working. You must also
check the lights every time you discon-
nect and then reconnect the wires.
Do not connect a trailer lighting system
directly to your vehicle’s lighting system.
Use only an approved trailer wiring har-
ness.
An authorised HYUNDAI dealer can
assist you in installing the wiring harness.
Driving on grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 70 km/h (45mph) to reduce the possibility of engine
and transaxle overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transaxle,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimise heat build up
and extend the life of your transaxle.WARNING
Failure to use an approved trailer wiring harness could result in dam-
age to the vehicle electrical system
and/or personal injury.

IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatic
transaxle, be sure the shift lever is in N
(Neutral) or P (Park) and the emer-
gency brake is set.
2. Check the battery connections to be sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you operate the
starter, the battery is discharged.
4. Check the starter connections to be sure they are securely tightened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump starting". If engine turns over normally but
does not start
1. Check fuel level.
2. With the ignition switch in the LOCK
/OFF position, check all connectors at
the ignition coils and spark plugs.
Reconnect any that may be discon-
nected or loose.
3. If the engine still does not start, call an authorised HYUNDAI dealer or seek
other qualified assistance.
WARNING
If the engine will not start, do not
push or pull the vehicle to start it.This could result in a collision or
cause other damage. In addition,
push or pull starting may cause the
catalytic converter to be over-
loaded and create a fire hazard.
