When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R), if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper
free of mud, dirt, snow, ice and slush. Other
conditions that may affect system performance
include things like the vibrations from a jackhammer
or the compression of air brakes on a very large
truck. If after cleaning the rear bumper and then
driving forward at least 15 mph (25 km/h), the
display continues to ash red, see your dealer.
If a trailer was attached to your vehicle, or a
bicycle or an object was hanging out of your trunk
during your last drive cycle, the light may also
ash red. The light will continue to ash whenever
in REVERSE (R) until your vehicle is driven
forward at least 15 mph (25 km/h) without any
obstructions behind the vehicle.
For cleaning instructions, seeWashing Your
Vehicle on page 480.
Accessory Power Outlet(s)
Your vehicle is equipped with accessory power
outlets. The outlets can be used to plug in
electrical equipment such as a cellular telephone,
CB radio, etc.
Your vehicle has one outlet in front of the center
console, one in the center console lid and
there may be an additional outlet in the rear of the
center console.
Your vehicle may have a small cap that must be
removed to access the accessory power outlet. If it
does, when not using the outlet be sure to cover
it with the protective cap.
Notice:Leaving electrical equipment plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.
