B260B01A-AATSRS (Airbag) Service
Reminder Indicator (SRI)
The SRS service reminder indicator (SRI) comes
on and flashes for about 6 seconds after the
ignition 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 SRI does not come on,
or continuously remains on after flashing 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-AATTurn 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.

the seat belt is fastened when the ignition key is
turned "ON" or "START".
And, the warning chime will also sound for about
6 seconds.
B260F01A-AATHigh Beam Indicator Light
The high beam indicator light comes on when-
ever the headlights are switched to the high
beam or flash position.
B260G01A-AATOil Pressure Warning Light
CAUTION:
If the oil pressure warning light stays on
while the engine is running, serious engine
damage may result. The oil pressure warn-
ing light comes on whenever there is insuf-
ficient 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 malfunction.
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 imme-
diately. 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.

2- 16 DRIVING YOUR HYUNDAI
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.
!
C180A01A-AATUSE OF LIGHTS
Check your lights regularly for correct opera-
tion and always keep them clean. When driving
during the day in conditions of poor visibility, it
is helpful to drive with headlights on low beam.
This enables you to be seen as well as to see.
C190A01S-AAT
TRAILER OR VEHICLE TOWING
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, or other types of
vehicles or apparatus may differ. Ask your
Hyundai dealer for further details before towing.
C190B01S-AATTrailer Hitches
Select the proper hitch and ball combination,
making sure that its 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.
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.
!
C190C01Y-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 Under
Severe Usage Conditions" on page 5-6.
