How the System Works
Unless disabled, the URPA will turn on automatically
when the shift lever is moved into REVERSE (R).
When the system turns on, the three lights on the
display will illuminate for one and a half seconds to let
you know that the system is working. If your vehicle
is moving in REVERSE (R) at a speed greater
than
3 mph (5 km/h), the red light will flash to remind
you that the system does not work at speed greater than
3 mph (5 km/h).
If an object is detected at a REVERSE (R) speed of
less than
3 mph (5 km/h), one of the following will occur:

When
the System Does Not Seem to
Work Properly
The light may flash 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 flash red,
see your dealer.
If a trailer was attached to your vehicle, or a bicycle or
an object was on the back of, or hanging out of your
liftgate during your last drive cycle, the light may
also flash red. The light will continue to flash 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, see
Cleaning the Outside of .I- I#-#-. I UUI vellrdc oli p/ayt. a-rv. r
URPA cannot detect objects that are above liftgate level.
In order for the rear sensors to recognize an object,
it must be within detection range behind the vehicle.

Warning Lights, Gages and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before
it becomes serious enough to cause
an expensive repair or replacement. Paying attention
to your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions.
As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the engine
just to let you know they’re working.
If you are familiar
with this section, you should not be alarmed when
this happens. Gages
can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays
on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
Your vehicle also has a message center that works
along with the warning lights and gages. See
Message
Center on page
3-52.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You’ll know how
fast you’re going, how much fuel you’re using, and many other things you’ll need
to drive safely and economically.
The indicator warning lights and gages are explained on the following pages.

You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even
several seconds, for your eyes to readjust to the dark.
When you are faced with severe glare (as from a
driver who doesn’t lower the high beams, or a vehicle
with misaimed headlamps), slow down a little. Avoid
staring directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean
- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it’s easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim,
so should your eyes
be examined regularly. Some drivers suffer from
night blindness
- the inability to see in dim light - and
aren’t even aware of it.
Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you can’t stop, accelerate or turn as well because
your tire-to-road traction isn’t as good as on dry roads.
And,
if your tires don’t have much tread left, you’ll get
even less traction. It’s always wise to go slower and
be cautious
if rain starts to fall while you are driving.
The surface may get wet suddenly when your reflexes
are tuned for driving on dry pavement.
