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-
sure warning light comes on whenever
there is insufficient oil pressure. In nor-
mal 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 en-
gine 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.

The brake fluid level warning light indi-
cates that the brake fluid level in the brake
master cylinder is low and hydraulic brake
fluid conforming to DOT 3 or DOT 4 speci-
fications 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.B260K01S-AAT

Parking Brake/Low Brake Fluid
Level Warning Light
WARNING:
If you suspect brake trouble, have your
brakes checked by a Hyundai dealer as
soon as possible. Driving your car with
a problem in either the brake electrical
system or brake hydraulic system is
dangerous, and could result in a serious
injury or death.Warning Light OperationThe parking brake/brake fluid level
warning light should come on when the
parking brake is applied and the ignition
switch is turned to "ON" or "START". After
the engine is started, the light should go
out when the parking brake is released.
If the parking brake is not applied, the
warning light should come on when the
ignition switch is turned to "ON" or "START",
then go out when the engine starts. If the
light comes on at any other time, you should
slow the vehicle and bring it to a complete
stop in a safe location off the roadway.

The low fuel level warning light comes on
when the fuel tank is approaching empty.

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.

B260P02Y-GAT
ABS Service Reminder
Indicator (SRI) (If Installed)
When the key is turned to the "ON" position,
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
"ON" or come on while driving, there
may be a problem with E.B.D. (Electronic
Brake Force Distribution).
If this occurs, avoid sudden stops and
have your vehicle checked by your
Hyundai dealer as soon as possible.

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
Tire Pressure Monitoring System is not
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.
B265W02JM-GAT
TPMS (Tire Pressure Moni-
toring System) malfunction
indicator
TPMS malfunction indicator comes on for
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
accelerator and slowly move to a safe
position off the road.

B290A03A-AATENGINE COOLANT TEMPERATURE
GAUGE
WARNING:Never remove the radiator cap when the
engine is hot. The engine coolant is under
pressure and could erupt and cause
severe burns. Wait until the engine is
cool before adding coolant to the
reservoir.The normal range is approximately in the
middle between "H" and "C". If it moves
across the dial to "H" (HOT), pull over and
stop as soon as possible and turn off the
engine. Then open the hood and, after the
engine has cooled, check the coolant level
(See "If the engine overheats" on the page
3-4.) and the water pump drive belt. If you
suspect cooling system trouble, have your
cooling system checked by a Hyundai dealer
as soon as possible.
