08 02.19 Engine exhaust cautions NOTICE A large amount of unburned gases flowing into the three−way catalytic converter may cause it to overheat and create a fire hazard. To prevent this and other damage, observe the following precautions: z Use only unleaded gasoline. z Do not drive with an extremely low fuel level; running out of fuel could cause the engine to misfire, creating an excessive load on the three− way catalytic converter. z Do not allow the engine to run at idle speed for more than 20 minutes. z Avoid racing the engine. z Do not push−start or pull −start your vehicle. z Do not turn off the engine switch while the vehicle is moving. z Keep your engine in good running order. Malfunctions in the engine electrical system, electronic ignition system/distributor ignition system or fuel systems could cause an extremely high three−way catalytic converter temperature. z If the engine becomes difficult to start or stalls frequently, take your vehicle in for a check−up as soon as possible. Remember, your Toyota dealer knows your vehicle and its three−way catalytic converter system best. z To ensure that the three−way catalytic converter and the entire emission control system operate properly, your vehicle must receive the periodic inspections required by the Toyota Maintenance Schedule. For scheduled maintenance information, refer to the "Scheduled Maintenance Guide" or "Owner's Manual Supplement". CAUTION D Exhaust gases include harmful carbon monoxide (CO) that is colorless and odorless. Inhaling exhaust gases may lead to death or a serious health hazard. D The exhaust should be checked occasionally. If there is a hole or crack caused by corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehicle inspected and repaired by your Toyota dealer. Failure to do so may allow exhaust gases to enter the vehicle, resulting in death or a serious health hazard. D If the vehicle is in a poorly ventilated area, turn the engine off. In a closed area, such as a garage, exhaust gases may collect and enter the vehicle. This may lead to death or a serious health hazard. D Do not remain for a long time in a parked vehicle with the engine running. If it is unavoidable, however, do so only in an unconfined area and adjust the heating or cooling system to force outside air into the vehicle. 275 2008 TACOMA from Apr. '08 Prod. (OM35898U)
