1- 44 FEATURES OF YOUR HYUNDAI
Your Hyundai is equipped with dual- diagonal braking systems. This means you still have braking on two wheelseven if one of the dual systems should fail. With only one of the dual systems working, more than normal pedal traveland greater pedal pressure are re- quired to stop the car. Also, the car will not stop in as short a distance with onlyhalf of the brake system working. If the brakes fail while you are driving, shift to a lower gear for additional enginebraking and stop the car as soon as it is safe to do so. B260J01A-GAT

CATALYTIC CONVERTER
HXGS509
All Hyundai vehicles are equippedwith a monolith type three-way cata-lytic converter to reduce the carbon monoxide, hydrocarbons and nitro- gen oxides contained in the exhaustgas. Exhaust gases passing through the catalytic converter may cause it to operate at a very high temperature.The introduction of large amounts of unburned gasoline into the exhaust may cause the catalytic converter tooverheat and create a fire hazard. This risk may be reduced by observ- ing the following:
Catalytic Converter o Do not touch the catalytic con-
verter or any other part of the exhaust system while the cata-lytic converter is hot. Shut off the engine, wait for at least one hour before touching the cata-lytic converter or any other part of the exhaust system.
o Remember that your Hyundai dealer is your best source of assistance.
o Do not stop your Hyundai over any combustible material suchas grass, paper, leaves or rags.These materials might contact the hot catalytic converter and a fire might result.
