Batteries normally produce explosive gases which can cause
personal injury. Therefore, do not allow flames, sparks or lighted
substances to come near the battery. When working near the battery,
always shield your face and protect your eyes. Always provide proper
ventilation.
When lifting a plastic-cased battery, excessive pressure on the
end walls could cause acid to flow through the vent caps,
resulting in personal injury and/or damage to the vehicle or battery.
Lift the battery with a battery carrier or with your hands on opposite
corners.
Keep batteries out of reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or clothing. Shield your eyes
when working near the battery to protect against possible splashing of
acid solution. In case of acid contact with skin or eyes, flush
immediately with water for a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed, call a physician immediately.
Battery posts, terminals and related accessories contain lead and
lead compounds. Wash hands after handling.
For information on transmission operation after the battery has been
disconnected see “Shift strategy” in the driving section.
To account for customer driving habits and conditions, your automatic
transmission (4R70W) electronically controls the shift quality by using an
adaptive learning strategy. The adaptive learning strategy is maintained
by power from the battery. When the battery is disconnected or a new
battery is installed, the transmission must relearn its adaptive strategy.
Optimal shifting will resume within a few hundred kilometers (miles) of
operation.
If the shift quality does not improve within a few hundred
kilometers (miles) of operation, or if the downshifts and other
throttle conditions do not function normally or after a long
deceleration period, see your dealer or a qualified service
technician as soon as possible.
Because your vehicle’s engine is also electronically controlled by a
computer, some control conditions are maintained by power from the
