✽
✽NOTICEA 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.
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 through self-diagnosis and the light will gooff if everything is normal. If the light stays on, you may have aproblem with your ABS. We rec- ommend that you contact aHYUNDAI authorised repairer.
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 vehicle over to a safe place andstop the engine.
 Restart the engine. If the ABS warning light is off, then yourABS system is normal. Otherwise, you may have a prob-lem with the ABS. We recommend that you contact a HYUNDAIauthorised repairer.

5Downhill brake control (DBC)
(if equipped)The Downhill Brake Control (DBC) sup-
ports the driver come down a steep hill
without the driver depressing the brake
pedal. It slows down the vehicle under 5
mph (8 km/h) with the automatic
transaxle or 5 mph (8 km/h) with the
manual transaxle and lets the driver con-
centrate on steering the vehicle.
DBC defaults to the OFF position when-
ever the ignition is turned on.
The DBC can be turned on or off by
pushing the button.
Standby
Press the DBC button when the vehicle speed is under
25 mph (40 km/h). The DBC system will turn ON and
enter the standby mode.
The system does not turn ON if the vehicle speed is
over 25 mph (40 km/h).
In the standby mode, if the vehicle speed is under 22
mph (35 km/h) whilst driving down a steep hill, the DBC
will activate automatically.
In the activated mode, the DBC will temporarily deacti-
vate under the following conditions:
 The hill is not steep enough.
 The brake pedal or accelerator pedal is depressed.If the above conditions are gone, the DBC will automat-
ically activate again.
The DBC will turn OFF under the following conditions:
 The DBC button is pressed again.
 The vehicle speed is over 38 mph (60 km/h).

5Active ECO operationActive ECO helps improve fuel efficiency
by controlling the engine, transaxle and
air conditioner. But fuel-efficiency can be
changed by the driver's driving habits
and road conditions.
 When the Active ECO button is
pressed the ECO indicator (green) will
illuminate to show that the Active ECO
is operating.
 When the Active ECO is activated, it does not turn off even though the
engine is restarted again. To turn off
the system, press the active ECO but-
ton again.
 If Active ECO is turned off, it will return to the ECO mode.
When Active ECO is activated: Vehicle noise may become loud.
 Vehicle speed may drop.
 The air conditioner performance maydecline.
Limitation of Active ECO opera-
tion :If the following conditions occur whilst
Active ECO is operating, the system
operation is limited even though there is
no change in the ECO indicator.
 When the coolant temperature is low:
The system will be limited until engine
performance becomes normal.
 When driving up a hill: The system will be limited to gain
power when driving uphill because the
engine torque is restricted.
 When using sports mode: The system will be limited according to
the shift location.

Driving your vehicle
ECONOMICAL OPERATIONYour 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
miles (kilometers) you can get from a
gallon (litre) of fuel. To operate your vehi-
cle as economically as possible, use the
following driving suggestions to help
save money in both fuel and repairs:
 Drive smoothly. Accelerate at a moder-ate rate. Don't make "jack-rabbit" starts
or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to the traffic so you don't have to
change speeds unnecessarily. Avoid
heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary braking. This also reduces
brake wear.
 Drive at a moderate speed. The faster you drive, the more fuel your vehicle
uses. Driving at a moderate speed,
especially on the highway, is one of the
most effective ways to reduce fuel con-
sumption.  Don't "ride" the brake or clutch pedal.
This can increase fuel consumption
and also increase wear on these com-
ponents. In addition, driving with your
foot resting 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 least
once 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 vehicle in good condition.
For better fuel economy and reduced
maintenance costs, maintain your vehi-
cle in accordance with the mainte-
nance schedule. If you drive your vehi-
cle in severe conditions, more frequent
maintenance is required.
 Keep your vehicle 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 vehicle. This
extra weight can result in increased
fuel consumption and also contribute
to corrosion.
 Travel lightly. Don't carry unnecessary weight in your vehicle. 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.

Driving your vehicle56
5 Remember, your vehicle does not
require extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
 Don't "labour" or "over-rev" the engine. Labouring is driving too slowly in too
high a gear resulting engine bucking. If
this happens, shift to a lower gear.
Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speeds.
 Use your air conditioning sparingly. The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
 Open windows at high speeds can reduce fuel economy.
 Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions. Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, we recommend that
you contact a HYUNDAI authorised
repairer to perform scheduled inspec-
tions and maintenance
WARNING
- Engine off dur-
ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
whilst driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury or
death.

5To keep locks from freezingTo 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 systemTo 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 a HYUNDAI authorised
repairer and most auto parts outlets. Do
not use engine coolant or other types of
anti-freeze as these may damage the
paint finish.
Don't let your parking brake
freezeUnder 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.
Do not park a vehicle on a public road
without the parking brake applied.Don't let ice and snow accumu-
late underneathUnder 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 vehicle to be sure the
movement of the front wheels and the
steering components is not obstructed.
Carry emergency equipmentDepending on the severity of the weath-
er, you should carry appropriate emer-
gency equipment. Some of the items you
may want to carry include tyre chains,
tow straps or chains, flashlight, emer-
gency flares, sand, a shovel, jumper
cables, a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.Don’t place foreign objects or
materials in the engine compart-
mentPlacement of foreign object or materials
which prevent cooling of the engine, in
the engine compartment, may cause a
failure or combustion. The manufacturer
is not responsible for the damage caused
by such placement.

Driving your vehicle
When you are ready to leave after park-
ing on a hill
1. With the manual transaxle in Neutralor automatic transaxle in P (Park),
apply your brakes and hold the brake
pedal down whilst you:
 Start your engine;
 Shift into gear; and
 Release the parking brake.
2. Slowly remove your foot from the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance when trailer towing Your vehicle will need service more often
when you regularly pull a trailer.
Important items to pay particular atten-
tion to include engine oil, automatic
transaxle fluid, axle lubricant and cooling
system fluid. Brake condition is another
important item to frequently check. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re trailering, it’s a good idea to review
these sections before you start your trip.
Don’t forget to also maintain your trailer
and towbar. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all towbar nuts
and bolts should be tight.
CAUTION
 Due to higher load during trailer usage, overheating might occurin hot days or during uphill driv-ing. If the coolant gauge indicatesover-heating, switch off the A/C and stop the vehicle in a safe areato cool down the engine.
 When towing check transaxle fluid more frequently.
 If your vehicle is not equipped with the air conditioner, youshould install a condenser fan toimprove engine performance when towing a trailer.

What to do in an emergency
IN CASE OF AN EMERGENCY WHILST DRIVINGIf the engine stalls at a crossroad
or crossing If the engine stalls at a crossroad orcrossing, set the shift lever in the N
(Neutral) position and then push the
vehicle to a safe place.
 If your vehicle has a manual transaxle not equipped with a ignition lock
switch, the vehicle can move forward
by shifting to the 2(second) or 3(third)
gear and then turning the starter with-
out depressing the clutch pedal.
If a puncture occurs whilst driv-
ing the vehicle1. Bring the car to rest as soon as it is safe to do so and with the minimum
amount of braking required which will
assist in maintaining the maximum
amount of control. The vehicle should
be parked wherever possible upon firm
level ground to facilitate wheel chang-
ing.
2. If the vehicle is creating a hazard and the road conditions do not permit the
wheel to be changed safely, assis-
tance should be sought.
3. Passengers must not be allowed to remain inside the vehicle during wheel
changing. If a puncture occurs whilst
the vehicle is on a motorway, the pas-
sengers should take refuge on the
motorway embankment to avoid the
possibility of injury occurring should
the vehicle be struck by other motor-
way traffic.
4. Wheel changing should be performed according to the following instructions.
If engine stalls whilst driving1. Reduce your speed gradually, keepinga straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your vehicle will not start, we recommend
that you contact a HYUNDAI autho-
rised repairer.

What to do in an emergency46IF THE ENGINE WILL NOT STARTIf engine cannot be cranked1. If your vehicle has an automatictransaxle, be sure the shift lever is in N
(Neutral) or P (Park) and the emer-
gency brake is set.
2. Check the battery terminals and con- nections to ensure that these are clean
and also tight.
3. If the interior lights dim when the engine is cranked and the battery ter-
minals have been checked, a dis-
charged battery is indicated.
4. Do not attempt to push or tow start the vehicle, refer to "Jump Starting" for
information regarding engine starting
when the battery is discharged.
If engine turns over normally but
does not start1. Check fuel level.
2. With the ignition switch in the LOCK/OFF position, check all connectors at
ignition, coil and spark plugs.
Reconnect any that may be discon-
nected or loose.
3. Check the fuel line in the engine com- partment.
4. If the engine still does not start, we recommend that you call a HYUNDAI
authorised repairer.
WARNING
If the engine refuses to start, no
attempt should be made to push or
tow start the vehicle. Vehicles with
automatic transaxle or fuel injec-
tion will not be able to be started in
this manner since no drive is trans-
mitted through the automatic
transaxle whilst the engine is not
running, and in the case of fuel
injected derivatives, the fuel pump
will not operate under tow start
conditions. In addition, if the vehi-
cle is equipped with an exhaust cat-
alyst, damage to the catalyst may
result if the vehicle is tow started.

What to do in an emergency
IF THE ENGINE OVERHEATSIf your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as itis safe to do so.
2. Place the shift lever in P (automatic transaxle) or neutral (manual
transaxle) and set the parking brake. If
the air conditioning is on, turn it off.
3. If engine coolant is running out under the vehicle or steam is coming out
from the bonnet, stop the engine. Do
not open the bonnet until the coolant
has stopped running or the steaming
has stopped. If there is no visible loss
of engine coolant and no steam, leave
the engine running and check to be
sure the engine cooling fan is operat-
ing. If the fan is not running, turn the
engine off.
4. Check to see if the water pump drive belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check
for coolant leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from
it when you stop). 5. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and we recom-
mend that you call a HYUNDAI autho-
rised repairer. 6. If the cause of the overheating cannot
be found, wait until the engine temper-
ature has returned to normal. Then, if
coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
base of the radiator fill opening. Fill the
coolant expansion tank to the halfway
mark. To ensure the correct water to
coolant mix is obtained after top up,
testing by a HYUNDAI authorised
repairer is required.
7. Proceed with caution, keeping alert for further signs of overheating. If over-
heating happens again, we recom-
mend that you call a HYUNDAI autho-
rised repairer.
CAUTION
 Serious loss of coolant indicates there is a leak in the cooling sys-tem and we recommend that the system be checked by a HYUNDAIauthorised repairer.
 When the engine overheats from low engine coolant, suddenlyadding engine coolant may causecracks in the engine. To prevent damage, add engine coolantslowly in small quantities.
WARNING
Whilst the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
