WARNING AND INDICATOR LIGHTSB260B01JM-AAT
SRS (Airbag) Warning Light
The SRS warning light comes on for about 6
seconds after the key is turned to the "ON"
position or after the engine is started, after which
it will go out.
This light also comes on when the SRS is not
working properly. If the AIRBAG warning light
does not come on, or continuously remains on
after operating for about 6 seconds when you
turned the ignition key to the "ON" position or
started the engine, or if it comes on while driving,
have the SRS inspected by an authorized
Hyundai dealer.B260D01A-AAT
Turn Signal Indicator Lights
The blinking green arrows on the instrument
panel show the direction indicated by the turn
signals. If the arrow comes on but does not blink,
blinks more rapidly than normal, or does not
illuminate at all, a malfunction in the turn signal
system is indicated. Your dealer should be
consulted for repairs.
B260E01NF-AAT
Seat Belt Reminder Light
and Chime (Driver's side)
The driver's seat belt reminder light blinks and
the warning chime sounds for 6 seconds when
the ignition key is turned from the "OFF" position
to the "ON" or "START" position to remind the
driver to fasten the driver's seat belt.B260F01A-AAT
High Beam Indicator Light
The high beam indicator light comes on when-
ever the headlights are switched to the high
beam or flash position.
B260G01A-AAT
Low Oil Pressure Warning Light
CAUTION:
If the low oil pressure warning light stays on
while the engine is running, serious engine
damage may result. The oil pressure warning
light comes on whenever there is insufficient
oil pressure. In normal operation, it should
come on when the ignition switch is turned on,
then go out when the engine is started. If the
oil pressure warning light stays on while the
engine is running, there is a serious malfunc-
tion.
If this happens, stop the car as soon as it is safe
to do so, turn off the engine and check the oil
level. If the oil level is low, fill the engine oil to
the proper level and start the engine again. If
the light stays on with the engine running, turn
the engine off immediately. In any instance
where the oil light stays on when the engine
is running, the engine should be checked by
a Hyundai dealer before the car is driven again.

Front Fog Light Indicator Light
This fog indicator light comes on when the
ignition key is turned to the "ON" position and the
front fog light switch is on.

DRIVING YOUR HYUNDAI

C160J01A-AATDon't Let Ice and Snow Accumulate
UnderneathUnder some conditions, snow and ice can build
up under the fenders and interfere with the
steering. When driving in severe winter condi-
tions where this may happen, you should peri-
odically check underneath the car to be sure the
movement of the front wheels and the steering
components is not obstructed.C160I01L-AATDon't Let Your Parking Brake FreezeUnder 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 tempo-
rarily while you put the gear selector lever in "P"
and block the rear wheels so the car cannot roll.
Then release the parking brake.
C160K01A-AATCarry Emergency EquipmentDepending on the severity of the weather where
you drive your car, 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 window scraper,
gloves, ground cloth, coveralls, a blanket, etc.
HIGHER SPEED MOTORINGC170A01A-AATPre-Trip Inspections1. Tires:
Adjust the tire inflation pressures to specifica-
tion. Low tire inflation pressures will result in
overheating and possible failure of the tires.
Avoid using worn or damaged tires which may
result in reduced traction or tire failure.NOTE:Never exceed the maximum tire inflation
pressure shown on the tires.
2. Fuel, engine coolant and engine oil:
High speed travel consumes more fuel than
urban motoring. Do not forget to check both
engine coolant and engine oil.
3. Drive belt:
A loose or damaged drive belt may result in
overheating of the engine.

CHECKING AND CHANGING THE
ENGINE COOLANT!
G050A01A-AAT
WARNING:
Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and may
erupt through the opening if the cap is
removed. You could be seriously burned if
you do not observe this precaution. Do not
remove the radiator cap until the radiator is
cool to the touch.
!
5. Remove the oil filter by turning it counter-
clockwise with a oil filter wrench of the proper
size. 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.
Tightening torque:
8.7 ~ 11.6 lb.ft (1.2 ~ 1.6 kgf.m)
Be sure that the mounting surface on the
engine is clean and that the old gasket is
removed completely. Lubricate the new
gasket on the filter with clean engine oil
before installation.
7. Remove the engine oil level dipstick.
8. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-
ter 9 for engine oil capacity.
CAUTION:
Slowly pour the recommended oil into a
funnel. Do not overfill to avoid damage to
the engine.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It is
suggested that it be placed in a sealed
container and taken to a service station for
reclamation. Do not pour the oil on the
ground or put it into the household trash.
PROPOSITION 65 WARNING:
Used engine oil may cause irritation or
cancer of the skin if left in contact with the
skin for prolonged periods of time. Used
engine oil contains chemicals that have
caused cancer in laboratory animals. Al-
ways protect your skin by washing your
hands thoroughly with soap and warm
water as soon as possible after handling
used oil.
!
9. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
10.Shut off the engine and recheck the oil level.
