CWTWC1U231Receiver of Tire Pressure Monitor Sensor

c. You notice a change in the sound of the exhaust system. d. You have had an accident involving damage to the exhaust system, un- derbody, or rear of the vehicle. THREE-WAY CATALYST The three-way catalyst is an emission control device installed in the exhaust system. Exhaust gases in the three-way catalyst are burned at high temperatures to help reduce pollutants. WARNING OThe exhaust gas and the exhaust system are very hot. Keep people, ani- mals or flammable materials away from the exhaust system components. ODo not stop or park the vehicle over flammable materials such as dry grass, waste paper or rags. They may ignite and cause a fire. CAUTION ODo not use leaded gasoline. Deposits from leaded gasoline seriously reduce the three-way catalyst's ability to help reduce exhaust pollutants. OKeep your engine tuned up. Malfunc- tions 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 no- ticeable loss of performance or other unusual operating conditions are de- tected. Have the vehicle inspected promptly by an INFINITI dealer. OAvoid driving with an extremely low fuel level. Running out of fuel could cause the engine to misfire, damaging the three-way catalyst. ODo not race the engine while warming it up. LOW TIRE PRESSURE WARNING SYSTEM This vehicle is equipped with the low tire pressure warning system. It monitors tire pressure of all tires except the spare. When the low tire pressure warning light is lit, one or more of your tires is signifi- cantly underinflated. The system also dis- plays pressure of all tires (except the spare tire) on the display screen by send- ing a signal from a sensor that is installed in each wheel. The low tire pressure warning system will activate only when the vehicle is driven at speeds above 20 MPH (32 km/h). Also, this system may not detect a sudden drop in tire pressure (for example, a flat tire while driving). Tire pressure rises and falls depending on the heat caused by the vehicle's operation and the outside temperature. Low outside temperature can lower the temperature of the air inside the tire which can cause a lower tire inflation pressure. This may cause the low tire pressure warning light to illuminate. If the warning light illuminates in low out- side temperatures as described above, check the tire pressure for all four tires. Starting and driving5-3 Z04.12.13/Y50-DX Adjust the tire pressure to the recom- mended COLD tire pressure shown on the Tire and Loading Information label to turn the low tire pressure warning light OFF. Frequently check the tire pressure informa- tion display on the monitor screen and ad- just pressure of each tire properly. See ™Vehicle information and settings∫ in the ™4. Monitor, climate, audio, phone and voice recognition systems∫ section for tire pressure monitor. Low tire pressure warning If the vehicle is being driven with low tire pressure (lower than 27 psi, 190 kPa), the LOW PRESSURE information message will be displayed on the monitor screen. The low tire pressure warning light comes on, and the chime sounds for about 10 sec- onds. If you select the tire pressure information in the display, the LOW PRESSURE informa- tion message will be displayed. For additional information regarding the above warning, see ™Warning/indicator lights and audible reminders∫ in the ™2. Instruments and controls∫ section. WARNING OIf the low tire pressure warning light flashes while driving, avoid sudden steering maneuvers or abrupt braking, reduce vehicle speed, pull off the road to a safe location and stop the vehicle as soonaspossible.Seriousvehicle damage could occur and may lead to an accident and could result in serious per- sonal injury. Check the pressure for all four tires. Adjust the pressure to the rec- ommended COLD tire pressure shown on the Tire and Loading Information label to turn the low tire pressure warning light OFF. If you have a flat tire, replace it with a spare tire as soon as possible. (See ™Flat tire∫ in the ™6. In case of emer- gency∫ section for changing a flat tire.) OIf your vehicle is equipped with run-flat tires, you can continue driving after you have a flat tire. However, remember that vehicle handling stability is reduced, whichcouldleadtoanaccident and personal injury. See ™Wheels and tires∫ in the ™8. Maintenance and do-it- yourself∫ section for more details and make sure to observe the cautions about run-flat tires. Failure to do so may result in a serious accident. OImmediatelyafterasparetireis mounted or a wheel is replaced, tire pres- sure will not be indicated on the display and the low tire pressure warning system will not function. Reset the system by driving the vehicle at over 25 MPH (40 km/h) for approximately 10 minutes. If tire pressure is not indicated after per- forming the resetting procedure above, contact an INFINITI dealer as soon as possible. OReplacing tires with those not originally specified by INFINITI could affect the proper operation of the low tire pressure warning system. ODo not inject any tire liquid or aerosol tire sealant into the tires, as this may cause a malfunction of the tire pressure sensors. 5-4Starting and driving Z04.12.21/Y50-DX CAUTION The low tire pressure warning system may not function properly when the wheels are equipped with tire chains or the wheels are buried in snow.
