If the oil pressure warning light
stays on while the engine is run-
ning, 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

Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the
brake fluid level immediately and add
fluid as required. Then check all brake

found, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any author-
ized HYUNDAI dealer for a brake sys-
tem inspection and necessary repairs.
Your vehicle is equipped with dual-diago-
nal 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 vehicle will not stop in as
short a distance with only a portion 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
vehicle as soon as it is safe to do so.
To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the engine start/
stop button is in the ON position.

for about 3 seconds when you turned the
engine start/stop button to the ON posi-
tion, 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.
These warning lights 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 lights illuminate while driv-
ing, reduce vehicle speed immediately
and stop the vehicle. Avoid hard braking
and overcorrecting at the steering wheel.
Inflate the tires to the proper pressure as
indicated on the vehicle’s tire information
placard.
