THREE-WAY CATALYST The three-way catalyst is an emission control device installed in the exhaust system. Exhaust gases in the converter are burned at high temperatures to help reduce pollutants. WARNING The exhaust gas and the exhaust system are very hot. Keep people, animals or flammable materials away from the exhaust system components. Do not stop or park the vehicle over flammable materials such as dry grass, waste paper or rags. They may ignite and cause a fire. Keep your engine tuned up. Malfunctions in the ignition, fuel injection, or electrical systems can cause overrich fuel flow into the three-way catalyst, causing it to overheat. Do not keep driving if the engine misfires, or if noticeable loss of performance or other unusual operating conditions are detected. Have the vehicle inspected promptly by an INFINITI dealer. Avoid driving with an extremely low fuel level. Running out of fuel could cause the engine to misfire, damaging the three-way catalyst. Do not race the engine while warming it up. Do not push or tow your vehicle to start the engine. They have higher ground clearance than passenger cars to make them capable of performing in a variety of on-pavement and off-road applications. This gives them a higher center of gravity than ordinary cars. An advantage of higher ground clearance is a better view of the road, allowing you to anticipate problems. However, they are not designed for cornering at the same speeds as conventional twowheel drive vehicles any more than lowslung sports cars are designed to perform satisfactorily under off-road conditions. If at all possible, avoid sharp turns or abrupt maneuvers particularly at high speeds. As with other vehicles of this type, failure to operate this vehicle correctly may result in loss of control or vehicle rollover. In a rollover crash, an unbelted person is significantly more likely to die than a person wearing a seatbelt. CAUTION Do not use leaded gasoline. Deposits from leaded gasoline will seriously reduce the three-way catalyst's ability to help reduce exhaust pollutants. ON-PAVEMENT AND OFF-ROAD DRIVING PRECAUTIONS (for AWD models) Utility vehicles have a significantly higher rollover rate than other types of vehicles. TIRE PRESSURE MONITORING SYSTEM (TPMS) (for models without run-flat tire only) Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire infla- Starting and driving 5-3
