Engine Coolant Heater - Cadillac ATS 2017 Owner's Manual

Engine Coolant Heater

Vehicles with the engine coolant
heater can use this option in cold
weather conditions at or below 18 °
C (0 °F) for easier starting and better
fuel economy during engine warm-up.
Plug in the coolant heater at least four
hours before starting your vehicle. An
internal thermostat in the plug-end of
the cord may exist which will prevent
engine coolant heater operation at
temperatures above 18 °C (0 °F).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is
clipped to the diagonal brace on
the passenger side of the engine
compartment.
Check the heater cord for
damage. If it is damaged, do not
use it. See your dealer for a
replacement. Inspect the cord for
damage yearly.
3. Plug it into a normal, grounded
110-volt AC outlet.
Warning
Improper use of the heater cord or
an extension cord can damage the
cord and may result in overheating
and fire.
Plug the cord into a
three-prong electrical utility
receptacle that is protected by
a ground fault detection
function. An ungrounded
outlet could cause an electric
shock.
Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.
Failure to use the
recommended extension cord
in good operating condition,
or using a damaged heater or
extension cord, could make it
overheat and cause a fire,
property damage, electric
shock, and injury.
Do not operate the vehicle
with the heater cord
permanently attached to the
DRIVING AND OPERATING
Warning (Continued)
vehicle. Possible heater cord
and thermostat damage could

Before starting the vehicle,
unplug the cord, reattach the
cover to the plug, and
securely fasten the cord. Keep
the cord away from any
moving parts.
4. Before starting the engine, be
sure to unplug and store the cord
as it was before to keep it away
from moving engine parts. If you
do not, it could be damaged.
Contact your dealer for information
on how long to use the heater in your
particular area.
