2007 CHEVROLET AVALANCHE park assist

The ultrasonic sensors are not kept clean.
So, be sure to keep your vehicle’s rear
bumper free of mud, dirt, snow, ice, and
slush. For cleaning instructions, seeWashing
Your Vehicle on page 541. If the DIC still
displays the PARKING ASSIST OFF
message after cleaning the bumper and
driving forward at a speed of at least
15 mph (25 km/h), see your dealer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air brakes
on a very large truck or other mechanical
devices that interfere with URPA performance.
When URPA is disabled without driver
action and the driver attempts to turn
URPA back on by pressing the rear park
aid button, the indicator light will ash
for 3 seconds and then stay lit to indicate
that URPA is off.As always, drivers should use care when
backing up a vehicle. Always look behind you,
being sure to check for other vehicles,
obstructions and blind spots.
For Driver Information Center messages
related to URPA, seeDIC Warnings and
Messages on page 267.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the
vehicle to your dealer to repair the system.

If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including speed
limit restrictions, having to do with trailering.
Make sure your rig will be legal, not only
where you live but also where you’ll be driving.
A good source for this information can be
state or provincial police.
Consider using a sway control. See “Hitches”
later in this section.
Don’t tow a trailer at all during the rst 500 miles
(800 km) your new vehicle is driven. Your
engine, axle or other parts could be damaged.
Then, during the rst 500 miles (800 km) that
you tow a trailer, don’t drive over 50 mph
(80 km/h) and don’t make starts at full throttle.
This helps your engine and other parts of your
vehicle wear in at the heavier loads.
You can tow in DRIVE (D). You may want
to shift the transmission to THIRD (3) or,
if necessary, a lower gear selection if the
transmission shifts too often (e.g.,
under heavy loads and/or hilly conditions).
See “Tow/Haul Mode” later in this section.Three important considerations have to do
with weight:
the weight of the trailer,
the weight of the trailer tongue
and the weight on your vehicle’s tires.
Tow/Haul Mode
Tow/haul is designed to assist while your vehicle
is pulling a large or heavy load or trailer.
Tow/haul is most useful while pulling such a load
in rolling terrain, in stop-and-go traffic, or when
you need improved low-speed control, such
as when parking. The purpose of the tow/haul
mode is to do the following:
Reduce the frequency and improve the
predictability of transmission shifts when
pulling a heavy trailer or a large or heavy load.
Provide the same solid shift feel when pulling
a heavy trailer or a large or heavy load as
when the vehicle is unloaded.
Improve control of vehicle speed while
requiring less throttle pedal activity when
pulling a heavy trailer or a large or
heavy load.
