For detailed information, refer to "Tires and wheels" F11-23. & California proposition 65 warning WARNING Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. In addition, certain fluids in vehicles and certain components of product wear contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. General information & Noise from under the vehicle NOTE You may hear a noise from under the vehicle approximately 5 hours after the engine is turned off. However, this does not indicate a malfunction. This noise is caused by operation of the fuel evaporation leakage checking system and is normal. The noise will stop after approximately 15 minutes. WARNING Driving at high speeds with excessively low tire pressures can cause the tires to deform severely and to rapidly become hot. A sharp increase in temperature could cause tread separation, and destruction of the tires. The resulting loss of vehicle control could lead to an accident. & California Perchlorate Advisory Certain vehicle components such as airbag modules, seatbelt pretensioners and keyless entry transmitter batteries may contain perchlorate material. Special handling may apply for service or vehicle end of life disposal. See www.dtsc.ca.gov/ hazardouswaste/perchlorate.
