BEFORE DRIVING
WARNING
Driving while distracted can
result in a loss of vehicle con-
trol, that may lead to an acci-
dent, severe personal injury,
and death. The driver’s primary
responsibility is in the safe and
legal operation of a vehicle, and
use of any handheld devices,
other equipment, or vehicle sys-
tems which take the driver’s
eyes, attention and focus away
from the safe operation of a
vehicle or which are not permis-
sible by law should never be
used during operation of the
vehicle.

547
Driving your vehicle
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 tires for
proper inflation before driv-
ing. For proper tire pressures,
refer to “Tires and wheels” in
section 8.
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 car.
For further information and
tread limits, refer to “Tires and
wheels” in section 7.

Driving your vehicle

Use high quality ethylene gly-
col 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 cool-
ing system, lubricates 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 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.
WARNING- Tire chains
The use of chains may
adversely affect vehicle han-
dling.
Do not exceed 20 mph (30
km/h) or the chain manufac-
turer’s recommended speed
limit, whichever 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.
CAUTION
Chains that are the wrong size
or improperly installed can
damage your vehicle's brake
lines, suspension, body and
wheels.
Stop driving and retighten the
chains any time you hear them
hitting the vehicle.

Driving your vehicle
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.
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to hap-
pen 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 gear shift lever in P
and block the rear wheels so the car
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
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
Carry emergency equipment
Depending on the severity of the
weather where you drive your car,
you should carry appropriate emer-
gency equipment. Some of the items
you may want to carry include tire
chains, tow straps or chains, flash-
light, emergency flares, sand, a
shovel, jumper cables, a window
scraper, gloves, ground cloth, cover-
alls, a blanket, etc.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign object or mate-
rials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion.
The manufacturer is not responsible
for the damage caused by such
placement.

What to do in an emergency
6 6
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, 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 (automat-
ic transmission) or neutral (manual
transmission) 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 underneath the hood,
stop the engine. Do not open the
hood until the coolant has flow
stopped. If there is no visible loss
of engine coolant and no steam,
leave the engine running and
check to be sure the engine cool-
ing 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 coolant
leaking from the radiator, hoses or
under the car. (If the air condition-
ing 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 bro-
ken 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
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.7.Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
WARNING
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts to pre-
vent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This
may result in 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 sys-
tem and this should be checked
as soon as possible by an
authorized HYUNDAI dealer.
