4. Plug the heater cord into theconnector in the front fascia.
5. 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.
(Continued)
Warning (Continued)
.Do not operate the vehicle
with the heater cord
permanently attached to the
vehicle. Possible heater cord
and thermostat damage could
occur.
. While in use, do not let the
heater cord touch vehicle
parts or sharp edges.
. Before starting the vehicle,
unplug the cord. Keep the
cord away from any moving
parts.
6. Before starting the engine, be sure to unplug and store
the cord.
7. Install the engine heater connector cover.
The length of time the heater should
remain plugged in depends on several
factors. Ask a dealer in the area where
you will be parking the vehicle for the
best advice on this.

It is dangerous to get out of the
vehicle if the vehicle is not in
P (Park) with the parking brake set.
The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle can
move suddenly. You or others could
be injured. To be sure the vehicle
will not move, even when you are
on fairly level ground, always set
the parking brake and shift to
P (Park). See Shifting Into Park 0186
. If you are towing a trailer, see
Driving Characteristics and Towing
Tips 0244. If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the parking

DRIVING AND OPERATING 215
Conditions that are associated with
low visibility, such as fog, rain, snow,
or road spray, may limit ACC
performance. Water droplets from rain
or snow that remain on the
windshield may also limit ACC’s
ability to detect objects.
Lighting Conditions Affecting ACC
The ACC front camera can be affected
by poor lighting conditions, and ACC
may have limited performance when:
.There are changes in brightness,
such as entering and exiting
tunnels, bridges, and overpasses.
. Low sun angles cause the camera
to not detect objects, or it is more
difficult to detect objects in the
same traffic lane.
. Lighting is poor in the evening or
early morning .
There are multiple changes in
brightness or shadows along the
vehicle roadway.
. In a tunnel without the headlamps
on, or in a tunnel when there is a
vehicle in front that does not have
its taillamps on.
. Subjected to strong light from
opposing lane traffic in the front
of the vehicle, such as high-beam
headlamps from oncoming traffic.
Accessory Installations and Vehicle
Modifications
Do not install or place any object
around the front camera windshield
area that would obstruct the front
camera view.
Do not install objects on top of the
vehicle that overhang and obstruct the
front camera, such as a canoe, kayak,
or other items that can be transported
on the vehicle roof.
Do not modify the hood, headlamps,
or fog lamps, as this may limit the
camera’s ability to detect an object. Cleaning the Sensing System
The camera sensor on the windshield
behind the rearview mirror can
become blocked by snow, ice, dirt,
mud, or debris. This area needs to be
cleaned for ACC to operate properly.
The vehicle headlamps may need to
be cleaned due to dirt, snow, or ice.
Objects that are not illuminated
correctly may be difficult to detect.
If ACC will not operate, regular cruise
control may be available. See
“Switching Between ACC and Regular
Cruise Control
”previously in this
section. Always consider driving
conditions before using either cruise
control system.
For cleaning instructions, see
“Washing the Vehicle ”under Exterior
Care 0324.
