Operating precautions for catalytic
converters (if equipped)
Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
Use only UNLEADED FUEL for petrol engine.
Do not operate the vehicle when there are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance.
Do not misuse or abuse the engine. Examples of misuse are coasting withthe ignition off and descending steep
grades in gear with the ignition off. Do not operate the engine at high idle
speed for extended periods (5 minutesor more).
Do not modify or tamper with any part of the engine or emission control sys-
tem. All inspections and adjustments
must be made by an authorised
HYUNDAI dealer.
Avoid driving with a very low fuel level. If you run out of petrol, it could causethe engine to misfire and result in
excessive loading of the catalytic con-
ver ter.
Failure to observe these precautionscould result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your
warranty.
WARNING - Fire
A hot exhaust system can ignite
flammable items under your vehi-
cle. Do not park, idle, or drive the
vehicle over or near flammable
objects, such as dry grass, paper,
leaves, etc.
