Battery
The battery is in the trunk, behind the trim panel, on the passenger side of the vehicle. Refer to the replacement number shown on the original battery label when a new battery is needed.
WARNING!
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.
After a power loss, such as disconnecting the battery or removing the maxi fuses in the power distribution fuse block, the following steps must be performed to calibrate the electronic throttle control. If this is not done, the engine will not run properly.
1. Turn the ignition on but do not start the engine.
2. Leave the ignition on for at least three minutes so that the electronic throttle control will cycle and re-learn its home position.
3. Turn the ignition off.
4. Start and run the engine for at least 30 seconds.
