the START or ON position. The warning
light should go off when the parking

rised 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 greaterpedal pressure are required to stop the
car. Also, the car will not stop in as short
a distance with only a portion of the
brake system working. If the brakes fail
whilst 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.
CAUTION
If the oil pressure warning light stays on whilst the engine is run-
ning, serious engine damage mayresult. The oil pressure warninglight comes on whenever there is insufficient oil pressure. In normal
operation, it should come on whenthe ignition switch is turned on,then go out when the engine is
started. If the oil pressure warninglight stays on whilst the engine isrunning, there is a serious malfunc-tion.
If this happens, stop the car assoon as it is safe to do so, turn off the engine and check the oil level. Ifthe oil level is low, fill the engine oilto the proper level and start the
engine again. If the light stays onwith the engine running, turn theengine off immediately. In any instance where the oil light stays on
when the engine is running, theengine should be checked by an authorised HYUNDAI dealer beforethe car is driven again.
