• Do not work on a vehicle with

the engine running in an
enclosed space, unless you are
sure you have enough
ventilation.

• Keep all lit cigarettes, open

flames and other lit material
away from the battery and all
fuel related parts.

If you disconnect the battery, the
engine must “relearn” its idle
conditions before your vehicle will
drive properly, as explained in
Battery in this chapter.
