Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, followthese suggestions:
Drive cautiously and allow extra dis-
tance for braking.
Avoid sudden movements in braking or steering.
When braking with non-ABS brakes pump the brake pedal with a light up-
and-down motion until the vehicle isstopped. If stalled in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, tyre chains, or other non-slip material under the drive
wheels to provide traction when stalled
in ice, snow, or mud. Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between 1st (First)
and R (Reverse) in vehicles equipped
with a manual transaxle or R (Reverse)
and any forward gear in vehicles
equipped with an automatic transaxle.
Do not race the engine, and spin the
wheels as little as possible. If you are still
stuck after a few tries, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating and possible dam-
age to the transaxle.
SPECIAL DRIVING CONDITIONS
1JBB3302
WARNING -
ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
WARNING - Downshifting
Downshifting with an automatic
transaxle, whilst driving on slipperysurfaces can cause an accident.
The sudden change in tyre speed
could cause the tyres to skid. Be
careful when downshifting on slip-
pery surfaces.
CAUTION
Prolonged rocking may cause engine over-heating, transaxle dam-age or failure, and tyre damage.

Tyres
Adjust the tyre inflation pressures to
specification. Low tyre inflation pressures
will result in overheating and possible
failure of the tyres.
Avoid using worn or damaged tyres
which may result in reduced traction or
tyre failure.
✽✽NOTICE
Never exceed the maximum tyre infla-
tion pressure shown on the tyres.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engineoil.
Drive belt
A loose or damaged drive belt may result
in overheating of the engine.
WARNING
Underinflated or overinflated tyres can cause poor handling,
loss of vehicle control, and sud-den tyre failure leading to acci-
dents, injuries, and even death.
Always check tyres for proper
inflation before driving. For prop-
er tyre pressures, refer to “Tyres
and wheels” in section 8.
Driving on tyres with no or insuf- ficient tread is dangerous. Worn-out tyres can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tyresshould be replaced as soon as
possible and should never be
used for driving. Always check
the tyre tread before driving your
car. For further information and
tread limits, refer to “Tyres and
wheels” in section 7.

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.

Parking on hills
Generally, if you have a trailer attached to
your vehicle, you should not park your
vehicle on a hill. People can be seriously
or fatally injured, and both your vehicle
and the trailer can be damaged if unex-
pectedly roll down hill. However, if you ever have to park your
trailer on a hill, here's how to do it:
1. Pull the vehicle into the parking space.
Turn the steering wheel in the direction
of the kerb (left if headed down hill,
right if headed up hill).
2. If the vehicle has a manual transaxle, place the car in neutral. If the vehicle
has an automatic transaxle, place the
car in P (Park).
3. Set the parking brake and shut off the vehicle.
4. Place chocks under the trailer wheels on the down hill side of the wheels.
5. Start the vehicle, hold the brakes, shift to neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6. Reapply the brakes, reapply the park- ing brake and shift the vehicle to R
(Reverse) for manual transaxle or P
(Park) for automatic transaxle.
7. Shut off the vehicle and release the vehicle brakes but leave the parking
brake set.CAUTION
When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the enginecoolant temperature gauge toensure the engine does not over- heat.
If the needle of the coolant tem-perature gauge moves across thedial towards “H” (HOT), pull overand stop as soon as it is safe to
do so, and allow the engine to idleuntil it cools down. You may pro-ceed once the engine has cooledsufficiently.
You must decide driving speed depending on trailer weight anduphill grade to reduce the possi-bility of engine and transaxle overheating.
WARNING - Parking on a
hill
Parking your vehicle on a hill with a
trailer attached could cause seri-
ous injury or death, should the trail-
er break loose.

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:

and

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 nutsand 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 area to cool down the engine.
When towing check transaxle fluid more frequently.
WARNING - Parking brake
It can be dangerous to get out of
your vehicle if the parking brake is
not firmly set.
If you have left the engine running,
the vehicle can move suddenly. You
or others could be seriously or
fatally injured.

Jump starting procedure
1. Make sure the booster battery is 12-
volt and that its negative terminal is
grounded.
2. If the booster battery is in another vehi- cle, do not allow the vehicles to touch.
3. Turn off all unnecessary electrical loads.
4. Connect the jumper cables in the exact sequence shown in the illustration.Connect one end of the first jumper
cable to the positive battery terminal of
the vehicle (1) and then connect the
other end to the positive battery termi-
nal of the booster battery (2). Proceed to connect the second jumper
cable to the negative battery terminal
of the booster battery (3) and then con-
nect the other end to an exposed metal
surface on the vehicle engine. DO NOT
CONNECT THIS CABLE TO THE
NEGATIVE BATTERY TERMINAL OFTHE VEHICLE. Do not allow the jumper cables to con-
tact anything except the correct battery
terminals or the correct ground. Do not
lean over the battery when making
connections.
5. Start the engine of the vehicle with the booster battery and let it run at 2,000
rpm, then start the engine of the vehi-
cle with the discharged battery.
If the cause of your battery discharging is
not apparent, you should have your vehi- cle checked by an authorised HYUNDAIdealer.
Push-starting
Your manual transaxle-equipped vehicle
should not be push-started because itmight damage the emission control sys-tem.
Vehicles equipped with automatic
transaxle cannot be push-started.
Follow the directions in this section for
jump-starting.
CAUTION - Battery cables
Do not connect the jumper cable
from the negative terminal of thebooster battery to the negative ter-minal of the discharged battery.
This can cause the discharged bat-tery to overheat and crack, releas-ing battery acid.
WARNING
Never tow a vehicle to start it
because the sudden surge forward
when the engine starts could cause
a collision with the tow vehicle.

What to do in an emergency
IF THE ENGINE OVERHEATS
If 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 it is 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 car or steam is coming out from
the bonnet, stop the engine. Do notopen 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 car. (If the air con-
ditioning had been in use, it is normal
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 call the
nearest authorised HYUNDAI dealer
for assistance. 6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature 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
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-heating happens again, call an autho-
rised HYUNDAI dealer for assistance.
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.
CAUTION
Serious loss of coolant indicates there is a leak in the cooling systemand this should be checked as soonas possible by an authorised HYUNDAI dealer.
