If the engine does not stop
immediately after the Engine Oil
Pressure Warning Light is illumi-
nated, severe damage could
result.
If the warning light stays on
whilst the engine is running, it
indicates that there may be seri-
ous engine damage or malfunc-
tion. In this case:
1. Stop the vehicle as soon as it
is safe to do so.
2. Turn off the engine and check
the oil level. If the oil level is
low, fill the engine oil to the
proper level.
3. Start the engine again. If the
warning light stays on after the
engine is started, turn the
engine off immediately. In this
case, we recommend that you
have the vehicle inspected by
an authorised HYUNDAI deal-
er.

engine to misfire and damage the
catalytic converter (if equipped).
Engine Coolant
Temperature Warning
Light
This warning light illuminates:
When the engine coolant tempera-
ture is above 120°C (248°F). This

This warning light blinks:
When you drive the vehicle more
