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



Keep gasoline away from rubber or leather parts.

CAUTION:



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



Even 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:



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.
