is
particularly
important when outside temperatures are below freezing.

Most
trips include extensive idling (such as frequent driving
in

You operate your vehicle
in
dusty areas or off-road frequently.

a
trailer or
use
a
carrier
on

first.

miles
(1
2
500
km)
or
12
months

whichever comes first.

An engine coolant heater can be
a
big help
if
you have to park outside
in
very
cold
weather,
0°F
(-
18OC)
or
colder. If
your
vehicle has this option,
see
“Engine Coolant Heater”
