Do not smoke or be near an open flame when working on the fuel
system.



Keep gasoline away from rubber and leather parts.

CAUTION:



Do not disconnect any part of the fuel system until you have
discharged the fuel system pressure.



After discharging the fuel pressure, place a cloth or equivalent
over fittings as you separate them to reduce the risk of fuel
spray on yourself or in the engine compartment.

NOTE:



When disconnecting the cable, some systems need to be
initialized after the cable is reconnected (See INITIALIZATION ).



After the ignition switch is turned off, the navigation system
requires approximately 90 seconds to record various types of
memory and settings. As a result, after turning the ignition
switch off, wait 90 seconds or more before disconnecting the
cable from the negative (-) battery terminal.
