Fuel, engine coolant and engine
oil:
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both engine coolant and
engine oil.
Drive belt:
A loose or damaged drive belt may
result in overheating of the engine.
WARNING
Underinflated or overinflated tires can cause poor handling,
loss of vehicle control, and
sudden tire failure leading to
accidents, injuries, and even
death. Always check the tires
for proper inflation before
driving. For proper tire pres-
sures, refer to section 8,
"Tires and wheels".
Driving on tires with no or insufficient tread is danger-
ous. Worn-out tires can result
in loss of vehicle control, col-
lisions, injury, and even death.
Worn-out tires should be
replaced as soon as possible
and should never be used for
driving. Always check the tire
tread before driving your vehi-
cle. For further information
and tread limits, refer to sec-
tion 7, "Tires and wheels".

WINTER DRIVING
Severe weather conditions in the
winter result in greater wear and
other problems. To minimize the
problems of winter driving, you
should follow these suggestions:
Snowy 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 neces-
sary to select tires equivalent in size
and type of the original equipment
tires. Failure to do so may adversely
affect the safety and handling of your
vehicle. Furthermore, speeding,
rapid acceleration, 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 operation 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.
✽ ✽NOTICE
Tire chains are not legal in all states.
Check the state laws before fitting
tire chains.
Snow tires
If you mount snow tires on your vehi-
cle, make sure they are radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
Keep in mind that the traction provid-
ed by snow tires on dry roads may
not be as high as your vehicle's orig-
inal equipment tires. You should drive
cautiously even when the roads are
clear. Check with the tire dealer for
maximum speed recommendations.
Do not install studded tires without
first checking local, state and munic-ipal regulations for possible restric-tions against their use.
WARNING- Snow tire size
Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your vehi-
cle may be adversely affected.

Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery 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 igni-
tion system
Inspect your spark plugs as
described in section 7 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.
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 heat-
ed key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized HYUNDAI dealer and
most auto parts outlets. Do not use
engine coolant or other types of anti-
freeze as these may damage the
paint finish.

Driving your vehicle
Don't let your parking brake
freeze
Under 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 temporarily while
you put the shift lever in P (automat-
ic transaxle) and block the rear
wheels so the vehicle cannot roll.
Then release the parking brake.
Don't let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere 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 equipment
Depending on the severity of the
weather, you should carry appropri-
ate emergency equipment. Some of
the items you may want to carry
include tire chains, tow straps or
chains, flashlight, emergency flares,
sand, a shovel, jumper cables, a win-
dow scraper, gloves, ground cloth,
coveralls or a blanket, etc.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign objects or
materials which prevent cooling of
the engine, in the engine compart-
ment, may cause a failure or com-
bustion. The manufacturer is not
responsible for the damage caused
by such placement.

TRAILER TOWING
If you are considering towing with
your vehicle, you should first check
with your state's Department of
Motor Vehicles to determine their
legal requirements.
Since laws vary the requirements for
towing trailers, cars, or other types of
vehicles or apparatus may differ. Ask
an authorized HYUNDAI dealer for
further details before towing.
Your vehicle can tow a trailer. To
identify what the vehicle trailering
capacity is for your vehicle, you
should read the information in
"Weight of the trailer" that appears
later in this section.Remember that trailering is different
than just driving your vehicle by itself.
Trailering means changes in han-
dling, durability, and fuel economy.
Successful, safe trailering requires
correct equipment, and it has to be
used properly.
This section contains many time-test-
ed, important trailering tips and safe-
ty rules. Many of these are important
for your safety and that of your pas-
sengers. Please read this section
carefully before you pull a trailer.
Load-pulling components such as
the engine, transaxle, wheel assem-
blies, and tires are forced to work
harder against the load of the added
weight. The engine is required to
operate at relatively higher speeds
and under greater loads. This addi-
tional burden generates extra heat.
The trailer also considerably adds
wind resistance, increasing the
pulling requirements.
WARNING - Towing a
trailer
If you don't use the correct
equipment and/or drive improp-
erly, you can lose control when
you pull a trailer. For example, if
the trailer is too heavy, the
brakes may not work well - or
even at all. You and your pas-
sengers could be seriously or
fatally injured. Pull a trailer only
if you have followed all the
steps in this section.
WARNING- Weight limits
Before towing, make sure the
total trailer weight, GCW (gross
combination weight), GVW
(gross vehicle weight), GAW
(gross axle weight) and trailer
tongue load are all within the
limits.
CAUTION
Pulling a trailer improperly can damage your vehicle and resultin costly repairs not covered byyour warranty. To pull a trailercorrectly, follow the advice inthis section.

Driving with a trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you must get to
know your trailer. Acquaint yourself
with the feel of handling and braking
with the added weight of the trailer.
And always keep in mind that the
vehicle you are driving is now a good
deal longer and not nearly so respon-
sive as your vehicle is by itself.
Before you start, check the trailer
hitch and platform, safety chains,
electrical connector(s), lights, tires
and mirror adjustment. If the trailer
has electric brakes, start your vehicle
and trailer moving and then apply the
trailer brake controller by hand to be
sure the brakes are working. This lets
you check your electrical connection
at the same time.
During your trip, check occasionally
to be sure that the load is secure,
and that the lights and any trailer
brakes are still working.
Following distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving your vehicle without a trailer.
This can help you avoid situations
that require heavy braking and sud-
den turns.
Passing
You'll need more passing distance up
ahead when you're towing a trailer.
And, because of the increased vehi-
cle length, you'll need to go much far-
ther beyond the passed vehicle
before you can return to your lane.
Due to the added load to the engine
when going uphill the vehicle may
also take longer to pass than it would
on flat ground.
Backing up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, just move your
hand to the left. To move the trailer to
the right, move your hand to the
right. Always back up slowly and, if
possible, have someone guide you.
Making turns
When you're turning with a trailer,
make wider turns than normal. Do
this so your trailer won't strike soft
shoulders, curbs, road signs, trees,
or other objects near the edge of the
road. Avoid jerky or sudden maneu-
vers. Signal well in advance before
turning or lane changes.

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 occasion-
ally to be sure the trailer bulbs are still
working. You must also check the
lights every time you disconnect and
then reconnect the wires.
Do not connect a trailer lighting sys-
tem directly to your vehicle's lighting
system. Use only an approved trailer
wiring harness.
An authorized HYUNDAI dealer can
assist you in installing the wiring har-
ness.
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 45
mph (70 km/h) to reduce the possi-
bility of engine and transaxle over-
heating.
Operating your vehicle in D (Drive)
when towing a trailer will minimize
heat build up and extend the life of
your transaxle.WARNING
Failure to use an approved trail-
er wiring harness could result
in damage to the vehicle electri-
cal system and/or personal
injury.

5119
Driving your vehicle
When you are ready to leave after
parking on a hill
1. With the 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 trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transaxle fluid, axle lubricant
and cooling system fluid. Brake con-
dition is another important item to
frequently check. Each item is cov-
ered 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 hitch. Follow the mainte-
nance schedule that accompanied
your trailer and check it periodically.
Preferably, conduct the check at the
start of each day’s driving. Most
importantly, all hitch nuts and bolts
should be tight.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 run-
ning, the vehicle can move sud-
denly. You or others could be
seriously or fatally injured.CAUTION
Due to higher load during trailer usage, overheatingmight occur in hot days orduring uphill driving. If thecoolant gauge indicates over-heating, switch off the A/C andstop the vehicle in a safe areato cool down the engine.
When towing check transaxle fluid more frequently.
