voltage, the rear window defroster au-
tomatically turns itself back on.

pends on driving habits and operating con-
ditions.

Keep tires at the recommended infla-
tion pressures.


Remove unnecessary loads.


Remove roof rack when not in use.


Allow engine to warm up under low
load use.


Avoid frequent acceleration and decel-
eration.

ing in cold weather, in stop-and-go traffic,
on short trips and in hilly country.
