•
Do not operate the vehicle when
there are signs of engine mal-

•
Do not operate the engine at
high idle speed for extended
periods (5 minutes or more).
•
Do not modify or tamper with
any part of the engine or emis-
sion control system. All inspec-
tions and adjustments must be
made by an authorized
HYUNDAI dealer.
•
Avoid driving with extremely
low fuel level.
Running out of fuel could
cause the engine to misfire,
damaging the catalytic con-
verter.
Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.
