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 in section 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures 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. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station.
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, consult
an authorized HYUNDAI dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
CAUTION
Chains that are the wrong size orimproperly installed can damageyour vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.
WARNING- Tire chains
The use of chains may adversely affect vehicle handling.
Do not exceed 30 km/h (20 mph) 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.

When you are ready to leave after park-
ing on a hill
1. With the manual transaxle in Neutral
or automatic transaxle in P (Park),
apply your brakes and hold the brake
pedal down while 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 is a good idea to
review these sections before you start
your trip.
Do not forget to also maintain your trailer
and hitch. 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 hitch 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 airconditioner and stop the vehicle in a safe area to cool down theengine.
When towing check transaxle fluid more frequently.
If your vehicle is not equipped with an air conditioner, youshould 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 will 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 hood, stop the engine. Do not
open the hood 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 call the
nearest authorized 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 author-
ized HYUNDAI dealer for assistance.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling systemand this should be checked as soonas possible by an authorizedHYUNDAI dealer.
WARNING
While 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 blow out of the
opening and cause serious burns.

Engine compartment precautions
(Diesel engine)
The injector operates at high voltage(maximum 200v). Therefore, the follow-
ing accidents may occur.
- Direct contact with the injector orinjector 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 while the engine is running.
- Do not touch the injector, injectorwirings, and the engine computer
while the engine is running.
- Do not remove the injector connector while the engine is running.
- People using pacemakers must not go near the engine while the engine
is starting or running.
WARNING- Maintenance work
Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorized HYUNDAI dealer.
Working under the hood 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 while work-
ing under the hood, make certain
that you remove all jewelry (espe-
cially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose cloth-
ing before getting near 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, injectors
and 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 the
ECU or wiring harness within the
engine room while engine is run-
ning, since the high currents in the
electronic engine control system
produce considerable magnetic
fields.
