{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
typical backing speeds of 3 mph (5 km/h) while
parking. And, the system does not detect
objects that are more than 5 feet (1.5 meters)
behind the vehicle.
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using Rear Park Assist,
always check carefully behind your vehicle
before you back up and then watch closely
as you do.URPA can be turned off by
pressing the rear park aid
disable switch located
in the overhead console
switchbank. While the
system is disabled,
an indicator light will be lit
on the switch. You will
not see any lights on the
rear display if the switch
is in the off position.
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 ¯ash 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:
Description English Metric
amber light 5 ft. 1.5 m
amber/amber lights 40 in. 1.0 m
amber/amber/red lights
& continuous chime20 in. 0.5 m
amber/amber/red
lights ¯ashing &
continuous chime1 ft 0.3 m
A chime will sound the ®rst time an object is detected
between 20 inches (0.5 m) and 5 feet (1.5 m) away.
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.
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 on the back of, or hanging out of your
liftgate 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.

Cleaning the Outside
of Your Vehicle on page 5-95.

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 brie¯y 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 Ð 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 3-53.

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.

Here are some tips on night driving.
·Drive defensively.
·Do not drink and drive.
·Adjust your inside rearview mirror to reduce
the glare from headlamps behind you.
·Since you can not see as well, you may need to
slow down and keep more space between you
and other vehicles.
·Slow down, especially on higher speed roads.
Your headlamps can light up only so much
road ahead.
·In remote areas, watch for animals.
·If you are tired, pull off the road in a safe
place and rest.
No one can see as well at night as in the daytime.
But as we get older these differences increase.
A 50-year-old driver may require at least twice as much
light to see the same thing at night as a 20-year-old.
What you do in the daytime can also affect
your night vision. For example, if you spend the day in
bright sunshine you are wise to wear sunglasses.Your eyes will have less trouble adjusting to night.
But if you are driving, do not wear sunglasses at night.
They may cut down on glare from headlamps, but
they also make a lot of things invisible.
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 does not 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 Ð 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 ®lm caused by dust. Dirty glass makes
lights dazzle and ¯ash 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 is 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 Ð the inability to see in dim light Ð and are
not even aware of it.
