Air conditioning system operation tips
 If the vehicle has been parked in direct
sunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
 To help reduce moisture inside of the windows on rainy or humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioningsystem.
 During air conditioning system opera- tion, you may occasionally notice aslight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
 Use the air conditioning system every month only for a few minutes to ensure
maximum system performance.  When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.
 Operating the air conditioning system in the recirculated air position provides
maximum cooling, however, continual
operation in this mode may cause the
air inside the vehicle to become stale.
 During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and humid air
intake. This is a normal system opera-
tion characteristic. Climate control air filter (if equipped) The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-cle from the outside through the heating
and air conditioning system. If dust or
other pollutants accumulate in the filter
over a period of time, the air flow from the
air vents may decrease, resulting in
moisture accumulation on the inside of
the windscreen even when the outside
(fresh) air position is selected. If this hap-
pens, we recommend that the climate
control air filter be replaced by a
HYUNDAI authorised repairer.

Driving your vehicle
Use high quality ethylene glycol coolant
Your vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule. Before winter,
have your coolant tested to assure that
its freezing point is sufficient for the tem-
peratures anticipated during the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. We recommend that the system be
checked by a HYUNDAI authorised
repairer.Change to "winter weight" oil if
necessary In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, we rec-
ommend that you consult a HYUNDAI
authorised repairer.
Check spark plugs and ignition system
Inspect your spark plugs and replace
them if necessary. Also check all ignition
wiring and components to be sure they
are not cracked, worn or damaged in any
way.
CAUTION
 Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-pension, body and wheels.
 Stop driving and retighten the chains any time you hear them
hitting the vehicle.
WARNING - Tyre chains
 The use of chains may adversely affect vehicle handling.
 Do not exceed 20 mph (30 km/h) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
 Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
 Avoid sharp turns or locked- wheel braking.

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 nutsand bolts should be tight.CAUTION
 Due to higher load during trailer
usage, overheating might occur
in 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.
 If your vehicle is not equipped with the air conditioner, you
should install a condenser fan toimprove engine performance when towing a trailer.

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 vehicle or steam is coming out
from the bonnet, stop the engine. Donot 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, ifcoolant 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 authorisedrepairer 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 systemand we recommend that the system
be checked by a HYUNDAI autho-rised repairer.
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.

Engine compartment precautions (Diesel engine)
• The piezo injector operates at high
voltage (maximum 200v). Therefore,
the following accidents may occur.
- Direct contact with the injector or
injector wiring may cause electric
shock or damage your muscle or
nerve system.
- The electromagnetic wave from the operating injector may cause the arti-
ficial heart pacemaker to malfunction.
 Follow the safety tips provided below, when you are checking the engine
room whilst the engine is running.
- Do not touch the injector, injector
wirings, and the engine computer
whilst the engine is running.
- Do not remove the injector connector whilst the engine is running.
- People using pacemakers must not go near the engine whilst the engine
is starting or running.
WARNING - Maintenance
work
 Performing maintenance work on a vehicle can be dangerous. You
can be seriously injured whilst
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, we recommend that the
system be serviced by a
HYUNDAI authorised repairer.
 Working under the bonnet with the engine running is dangerous.
It becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine whilst work-
ing under the bonnet, make cer-
tain that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before gettingnear the engine or cooling fans.WARNING - Diesel Engine
Never work on injection system with engine running or within 30
seconds after shutting off engine.
High-pressure pump, rail, injectorsand high-pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touches the body.
People using pacemakers should
not move than 30cm closer to theECU or wiring harness within the
engine room whilst engine is run-
ning, since the high currents in the
electronic engine control system
produce considerable magneticfields.

Maintenance
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or fuelfiller cap is correctly replaced.
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold. Inspect the hose routing to assure that the hoses do not come in contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.Air cleaner filter
We recommend that you use air cleaner
filter for replacement from a HYUNDAI
authorised repairer.
Spark plugs (for petrol engine)
Make sure to install new spark plugs of
the correct heat range. Cooling system
Check the cooling system parts, such as
radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts. Coolant The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid (if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
Automatic transaxle fluid (if equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, we recommend
that the fluid be changed by a HYUNDAI
authorised repairer in accordance to thescheduled maintenance at the beginning
of this chapter.
✽✽
NOTICE
Automatic transaxle fluid colour is basi-
cally red. As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.It is normal condition and you should
not judge the need to replace the fluid
based upon the changed colour.
