Disconne cting the batt e ry t erminals
Some vehicle functions (power w indow regu -
lators, for example) are lost if the battery ter-
minals are disconnected . These functions have
to be relearned after the battery terminals are
connected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
Vehicle s not driven fo r long period s

During the winter months, battery capacity
tends to decrease as tempe ratures d rop . This
is because more powe r is also consumed while
start ing, and the headl ights, rea r window de -

Avoid unnecessary power consumption, par-

charged battery will not only prevent starting
prob lems when the weather is cold, but will
also last longer .
If your vehicle is left standing for severa l
weeks at extremely low temperat ures, the
veh icle battery should be removed and
stored where it will not freeze. This will
prevent it from bei ng damaged and having
to be replaced.
