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.

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.

a door is not completely closed and the
chime warns you that the key is in the
ignition switch.NOTE :The warning chime only sounds

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.

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.

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.
