exposed cable end to prevent electrical shorts.

system to lose memory of some "learned" functions,

Maintaining your Vehicle section under the Mainte-
nance Procedures sub-section, within Maintenance-
Free Battery. The engine may run rough when first
started after a battery disconnect until the control
module "relearns" these functions.
Check the battery every 4 to 6 weeks to ensure that the

Service Manual.

pressure, (29 PSI).
