WARNING:
Never remove the radiator cap when the
engine is hot. The engine coolant is under
pressure and could erupt and cause severe
burns. Wait until the engine is cool before
removing the radiator cap.
The needle on the engine coolant temperature
gauge should stay in the normal range. If it
moves across the dial to "H" (Hot), pull over and
stop as soon as possible and turn off the engine.
Then open the hood and, after the engine has
cooled, check the coolant level and the water
pump drive belt. If you suspect cooling system
trouble, have your cooling system checked by
a Hyundai dealer as soon as possible.

2DRIVING YOUR HYUNDAI
15WINTER DRIVING
C160A01A-AAT
The more severe weather conditions of winter
result in greater wear and other problems. To
minimize the problems of winter driving, you
should follow these suggestions:
C160B01A-AATSnowy or Icy Conditions
To drive your vehicle in deep snow, it may be
necessary to use snow tires or to install tire
chains on your tires. If snow tires are needed,
it is necessary to select tires equivalent in size
and type to the original equipment tires. Failure
to do so may adversely affect the safety and
handling of your car. Speeding, rapid accelera-
tion, sudden brake applications, and sharp
turns are potentially very hazardous practices.
During deceleration, use engine braking to the
fullest extent. Sudden brake applications on
snowy or icy roads may cause skids to occur.
You need to keep sufficient distance between
the vehicle in front and your vehicle. Also, apply
the brake gently. It should be noted that installing
tire chains on the tire will provide a greater
driving force, but will not prevent side skids.
NOTE:Tire chains are not legal in all states. Check
state laws before fitting tire chains.
C160C01A-AAT
Use High Quality Ethylene Glycol
Coolant
Your Hyundai 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 cool-
ing system, lubricates the water pump and
prevents freezing. Be sure to replace or replen-
ish your coolant in accordance with the main-
tenance schedule in Section 5. Before winter,
have your coolant tested to assure that its
freezing point is sufficient for the temperatures
anticipated during the winter.
C160D01A-AATCheck Battery and Cables
Winter puts additional burdens on the battery
system. Visually inspect the battery and cables
as described in Section 6. The level of charge
in your battery can be checked by your Hyundai
dealer or a service station.
C160E01A-AAT
Change to "Winter Weight" Oil if Neces-
sary
In some climates it is recommended that a lower
viscosity "winter weight" oil be used during cold
weather. See Section 9 for recommendations.
If you aren't sure what weight oil you should use,
consult your Hyundai dealer.
C160F01A-AATCheck Spark Plugs and Ignition System
Inspect your spark plugs as described in Sec-
tion 6 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.
C160G01A-AAT
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.

2DRIVING YOUR HYUNDAI
17TRAILER OR VEHICLE TOWING
C190A02S-AAT
If you are considering towing with your car, you
should first check with your State's Department
of Motor Vehicles to determine their legal re-
quirements.
Since laws vary from State to State, the require-
ments for towing trailers, cars, other types of
vehicles, or apparatus may differ. Ask your
Hyundai dealer for further details before towing.
CAUTION:Do not do any towing with your car during
its first 1,200 miles (2,000 km) in order to
allow the engine to properly break in. Fail-
ure to heed this caution may result in seri-
ous engine or transaxle damage.
!
C190B01S-AAT
Trailer Hitches
Select the proper hitch and ball combination,
making sure that it's location is compatible with
that of the trailer or vehicle being towed.
Use a quality non-equalizing hitch which distrib-
utes the tongue load uniformly throughout the
chassis.
The hitch should be bolted securely to the car
and installed by a qualified technician. DO NOT
USE A HITCH DESIGNED FOR TEMPORARY
INSTALLATION AND NEVER USE ONE THAT
ATTACHES ONLY TO THE BUMPER.
C190C03S-AATTrailer Brakes
If your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed and
operating correctly.
NOTE:If you tow a trailer or vehicle, your car will
require more frequent maintenance due to
the additional load. See "Maintenance Un-
der Severe Usage Conditions" on page 5-6.
C190D01S-AAT
Safety Chains
Should the hitch connection between your car
and the trailer or vehicle you are towing fail, the
trailer or vehicle could wander dangerously
across other lanes of traffic and ultimately leave
the roadway. To eliminate this potentially dan-
gerous situation, safety chains, attached be-
tween your car and the trailer or towed vehicle,
are required in most states.
!CAUTION:o Never connect a trailer brake system
directly to the vehicle brake system.
o When towing a trailer on steep grades (in
excess of 12%) pay close attention to the
engine coolant temperature gauge to
ensure the engine does not overheat. If
the needle of the coolant temperature
gauge moves across the dial towards
"H" (HOT), pull over and stop as soon as
it is safe to do so, and allow the engine
to idle until it cools down. You may
proceed once the engine has cooled
sufficiently.

3WHAT TO DO IN AN EMERGENCY
4IF THE ENGINE OVERHEATS
!
!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.
5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the engine
immediately and call the nearest Hyundai
dealer for assistance.
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 seri-
ous burns.
6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has
returned to normal. Then, if coolant has been
lost, carefully add coolant to the reservoir
(page 6-9) to bring the fluid level in the
reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur-
ther signs of overheating. If overheating
happens again, call a Hyundai dealer for
assistance.
D030A01A-AAT
If your temperature gauge indicates overheat-
ing, you experience a loss of power, or hear loud
pinging or knocking and the engine is probably
too hot. If this happens and, you should:
1. Pull off the road and stop as soon as it is safe
to do so.
2. Place the gear selector lever in "P" (auto-
matic), 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 hood, stop
the engine. Do not open the hood until the
engine 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 operating. 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 engine coolant leak-
ing from the radiator, hoses or under the car.
(If the air conditioning had been in use, it is
normal for cold water to be draining from it
when you stop). post or cable of the booster battery. Then
attach the other end of that cable to a solid
metal part of the engine away from the
battery. Do not connect the cable to any
moving part.
4. Start the engine in the car with the booster
battery and let it run for a few minutes. This
will help to assure that the booster battery is
fully charged. During the jumping operation,
run the engine in this vehicle at about 2,000
rpm.
5. Start the engine in the car with the dis-
charged battery using the normal starting
procedure. After the engine starts, leave the
jumper cables connected and let the engine
run at fast idle or about 2,000 rpm for several
minutes.
6. Carefully remove the jumper cables in the
reverse order of attachment.
If you do not know why your battery became
discharged (because the lights were left on,
etc.), have the charging system checked by
your Hyundai dealer.

drains out, then remove the drain plug.
WARNING:Be very careful when draining the engine oil
as it may be hot enough to burn you!
G030D01A-AAT
Adding Oil
The engine oil and filter should be changed at
those intervals specified in the maintenance
schedule in Section 5. If the car is being driven
in severe conditions, more frequent oil and filter
changes are required.
The procedure for changing the oil and filter is
as follows:
1. Park the car on level ground and set the
parking brake. Start the engine and let it
warm up until the needle on the coolant
temperature gauge moves above the lowest
mark. Turn the engine off and place the gear
selector lever in "P" (automatic) or reverse
gear (manual transaxle). Set the parking
brake.4. When the oil has stopped draining, replace
the drain plug using a new washer and
retighten by turning it clockwise.
Drain plug tightening torque:
4.0 ~ 4.5 kgf.m
5. Remove the oil filter. You should be able to
unscrew the filter with your hands. (If your
hands are slippery, try to use a cloth be-
tween your hands and the filter to give
yourself a better grip.) A certain amount of oil
will come out when you remove the filter, so
be sure to have your drain pan in place
underneath it.
6. Install a new oil filter in accordance with the
instructions on the carton or on the filter itself.
Do not over-tighten.

To Check the Coolant Level
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "LOW" and "FULL"
lines on the reservoir when the engine is cold.
If the level is below the "LOW" mark, add engine
coolant to bring it up between "LOW" and "FULL".
If the level is low, inspect for coolant leaks and
recheck the fluid level frequently. If the level
drops again, visit your Hyundai dealer for an
inspection and diagnosis of the reason.
G050B01A-AAT
Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts.
Additional corrosion inhibitors or additives should
not be used. The cooling system must be
maintained with the correct concentration and
type of engine coolant to prevent freezing and
corrosion. Never allow the concentration of
antifreeze to exceed the 60% level or go below
the 35% level, or damage to the cooling system
may result. For proper concentration when
adding or replacing the engine coolant, refer to
the following table.
