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 pres-

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 en-
gine off immediately. In any instance
where the oil light stays on when the
engine is running, the engine should be

B260M01A-AAT
Low Fuel Level Warning Light
The low fuel level warning light comes on
when the fuel tank is approaching empty.
When it comes on, you should add fuel as
soon as possible. Driving with the fuel
level warning light on or with the fuel level
below "E" can cause the engine to misfire
and damage the catalytic converter.B260N02A-AAT
Check Engine - Malfunction
Indicator Light (MIL)
This light illuminates when there is a
malfunction of an exhaust gas related
component, and the system is not
functioning properly so that the exhaust
gas regulation values are not satisfied. This
light will also illuminate when the ignition key
is turned to the "ON" position, and will go out
in a few seconds after the engine is started.
If it illuminates while driving, or does not
illuminate when the ignition key is turned to
the "ON" position, take your car to your
nearest authorized Hyundai dealer and have
the system checked. The brake fluid level warning light indicates
that the brake fluid level in the brake master
cylinder is low and hydraulic brake fluid
conforming to DOT 3 or DOT 4 specifications
should be added. After adding fluid, if no
other trouble is found, the car should be
immediately and carefully driven to a
Hyundai dealer for inspection. If further
trouble is experienced, the vehicle should
not be driven at all but taken to a dealer by
a professional towing service.
Your Hyundai is equipped with dual-
diagonal braking systems. This means
you still have braking on two wheels even
if one of the dual systems should fail. With
only one of the dual systems working,
more than normal pedal travel and greater
pedal pressure are required to stop the
car. Also, the car will not stop in as short a
distance with only half of the brake system
working. If the brakes fail while you are
driving, shift to a lower gear for additional
engine braking and stop the car as soon as
it is safe to do so.
B260J01NF-AAT
Charging System Warning
Light
The charging system warning light should
come on when the ignition is turned on,
then go out when the engine is running. If
the light stays on while the engine is
running, there is a malfunction in the
electrical charging system. If the light comes
on while you are driving, have the system
checked by your Hyundai dealer as soon
as possible.

ABS Service Reminder
Indicator (SRI) (If Installed)

the Anti-Lock Brake System indicator will
come on and then go off in a few seconds.
If the ABS SRI remains on, comes on while
driving, or does not come on when the key
is turned to the "ON" position, this indicates
that there may be a problem with the ABS.
If this occurs, have your vehicle checked
by your Hyundai dealer as soon as
possible. The normal braking system will
still be operational, but without the
assistance of the anti-lock brake system.
WARNING:
If both the ABS SRI and Parking Brake/
Brake fluid level warning lights remain

WARNING:
Significantly low tire pressure makes
the vehicle unstable and can contribute
to loss of vehicle control and increased
braking distances.
Continued driving on low pressure tires
will cause the tires to overheat and fail.
B260W02JM-GAT
Low tire pressure telltale
The low tire pressure telltale comes on for
3 seconds after the ignition key is turned to
the "ON" position.
If the warning light does not come on, the

working properly. If this occurs, have your
vehicle checked by an authorized Hyundai
dealer as soon as possible.
This warning light will also illuminate if one
or more of your tires are significantly under-
inflated. You should stop and check your
tires as soon as possible. If the warning
light illuminates while driving, reduce
vehicle speed immediately and stop the
vehicle. Avoid hard braking and overcor-
recting at the steering wheel. Inflate the
tires to the proper pressure as indicated on
the vehicle’s tire information placard.
After adjusting the tire pressure of each
wheel correctly, if the low pressure telltale
light stays “ON” continuously, the Tire
Pressure Monitoring System is not working
properly. If this occurs, have your vehicle
checked by an authorized Hyundai dealer
as soon as possible.

3 seconds after the ignition key is turned to
the "ON" position. If the warning light does
not come on, or continuously remains on
after coming on for about 3 seconds when
you turned the ignition key to the "ON"
position, the Tire Pressure Monitoring
System is not working properly. If this
occurs, have your vehicle checked by an
authorized Hyundai dealer as soon as
possible.
The warning light also comes on and stays
on when there is a problem with the Tire
Pressure Monitoring System.
If this happens, the system may not monitor
the tire pressure. Have the system checked
by an authorized Hyundai dealer as soon
as possible.
WARNING:
o The TPMS cannot alert you to severe
and sudden tire damage caused by
external factors.
o If you feel any vehicle instability, im-
mediately take your foot off the
