2007 CHEVROLET AVALANCHE instrument panel

Backing Up
Hold the bottom of the steering wheel with
one hand. Then, to move the trailer to the left,
just move that hand to the left. To move the trailer
to the right, move your hand to the right. Always
back up slowly and, if possible, have someone
guide you.
Making Turns
Notice:Making very sharp turns while
trailering could cause the trailer to come in
contact with the vehicle. Your vehicle could
be damaged. Avoid making very sharp
turns while trailering.
When you’re turning with a trailer, make wider
turns than normal. Do this so your trailer
won’t strike soft shoulders, curbs, road signs,
trees or other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
The arrows on your instrument panel will
ash whenever you signal a turn or lane change.
Properly hooked up, the trailer lamps will also
ash, telling other drivers you’re about to
turn, change lanes or stop.
When towing a trailer, the arrows on your
instrument panel will ash for turns even if the
bulbs on the trailer are burned out. Thus, you
may think drivers behind you are seeing
your signal when they are not. It’s important to
check occasionally to be sure the trailer bulbs
are still working.

Electric Brake Control Wiring
Provisions
These wiring provisions are included with your
vehicle as part of the heavy-duty trailer wiring
package. These provisions are for an electric
brake controller. The instrument panel contains
blunt cut wires near the data link connector for
the trailer brake controller. The harness contains
the following wires:
Dark Blue: Auxiliary
Red/Black: Battery #
Light Blue: Brake Switch
White: Ground
The trailer brake controller should be installed
by your dealer or a qualied service center.
Trailer Recommendations
You must subtract your hitch loads from the
Cargo Weight Rating (CWR). CWR is the
maximum weight of the load your vehicle can
carry. It doesn’t include the weight of the people
inside, but you can gure about 150 lbs. (68 kg)
for each seat. The total cargo load must not
be more than your vehicles CWR.
Weigh your vehicle with your trailer attached,
so that you won’t go over the GVWR or GAWR.
If you are using a weight-distributing hitch,
weigh the vehicle without the spring bars in place.
You’ll get the best performance if you spread
out the weight of your load the right way, and if
you choose the correct hitch and trailer brakes.

Adding Equipment to the Outside
of Your Vehicle
Things you might add to the outside of your
vehicle can affect the airow around it. This may
cause wind noise and affect windshield washer
performance. Check with your dealer before
adding equipment to the outside of your vehicle.
Fuel
Use of the recommended fuel is an important
part of the proper maintenance of your vehicle.
To help keep your engine clean and maintain
optimum vehicle performance, GM recommends
the use of gasoline advertised as TOP TIER
Detergent Gasoline.The 8th digit of your Vehicle Identication
Number (VIN) shows the code letter or number
that identies your engine. You will nd the VIN at
the top left of the instrument panel. SeeVehicle
Identication Number (VIN) on page 546.
If your vehicle has the 5.3L V8 engine (VIN Code 0)
or the 5.3L V8 engine (VIN Code 3), you may use
either regular unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85); also see
Fuel E85 (85% Ethanol) on page 438. In all other
engines, use only regular unleaded gasoline.
435

Fuel E85 (85% Ethanol)
The 8th digit of your Vehicle Identication
Number (VIN) shows the code letter or number
that identies your engine. You will nd the VIN at
the top left of the instrument panel. SeeVehicle
Identication Number (VIN) on page 546.
If your vehicle has the 5.3L V8 engine (Code 0)
or the 5.3L V8 engine (Code 3), you may use
either regular unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85); also see
Fuel on page 435. In all other engines, use only
the unleaded gasoline described underGasoline
Octane on page 436.
Only vehicles that have the 5.3L V8 engine
(Code 0) or the 5.3L V8 engine (Code 3) may
use 85% ethanol fuel (E85). General Motors
encourages the use of E85 in vehicles that are
designed to use it. The ethanol in E85 is a
“renewable” fuel, meaning it is made from
renewable sources such as corn and
other crops.Many service stations will not have an 85% ethanol
fuel (E85) pump available. The U. S. Department
of Energy has an alternative fuels website
(www.eere.energy.gov/afdc/infrastructure/
locator.html) that can help you nd E85 fuel.
Those stations that do have E85 should have a
label indicating ethanol content. Do not use the fuel
if the ethanol content is greater than 85%.
At a minimum, E85 should meet ASTM
Specication D 5798. By denition, this means
that fuel labeled E85 will have an ethanol content
between 70% and 85%. Filling the fuel tank
with fuel mixtures that do not meet ASTM
specications can affect driveability and could
cause the check engine light to come on.
To ensure quick starts in the wintertime, the
E85 fuel must be formulated properly for your
climate according to ASTM specication D 5798.
If you have trouble starting on E85, it may
be because your E85 fuel is not properly
formulated for your climate. If this happens,
switching to gasoline or adding gasoline
to your fuel tank may improve starting.

Adding Coolant
If you need more coolant, add the proper
DEX-COOL®coolant mixture at the surge tank,
but only when the engine is cool. SeeCooling
System on page 464.
{CAUTION:
You can be burned if you spill coolant
on hot engine parts. Coolant contains
ethylene glycol, and it will burn if the
engine parts are hot enough. Do not
spill coolant on a hot engine.
When replacing the pressure cap, make sure
it is hand-tight and fully seated.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
The coolant surge tank pressure cap must be fully
installed on the coolant surge tank. SeeEngine
Compartment Overview on page 444for more
information on location.
Engine Overheating
You will nd a coolant temperature gage on your
vehicle’s instrument panel. SeeEngine Coolant
Temperature Gage on page 249.
In addition, you will nd an ENGINE
OVERHEATED STOP ENGINE, ENGINE
OVERHEATED IDLE ENGINE, and an ENGINE
POWER IS REDUCED message in the Driver
Information Center (DIC) on the instrument panel.
SeeDIC Warnings and Messages on page 267.
460

When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol located on the instrument panel
cluster. If your vehicle has the DIC feature, a
message to check the pressure in a specic tire
will also appear on the DIC display. The low
tire pressure warning symbol on the instrument
panel cluster and the CHECK TIRE PRESSURE
warning message on the DIC display will appear at
each ignition cycle until the tires are inated to
the correct ination pressure. For additional
information and details about the DIC operation
and displays seeDIC Operation and Displays
(With DIC Buttons) on page 258orDIC Operation
and Displays (Without DIC Buttons) on page 264
andDIC Warnings and Messages on page 267.
You may notice, during cooler weather conditions,
that the tire pressure monitor light, located on
the instrument panel cluster, and the CHECK TIRE
PRESSURE message will appear when the
vehicle is rst started and then turn off as you
start to drive the vehicle. This could be an early
indicator that the tire pressures are getting low and
need to be inated to the proper pressure.Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the
vehicle manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires
of a different size than the size indicated on
the vehicle placard or tire ination pressure label,
you should determine the proper tire ination
pressure for those tires.)
As an added safety
feature, your vehicle
has been equipped
with a tire pressure
monitoring system
(TPMS) that illuminates
a low tire pressure
telltale when one
or more of your tires
is signicantly
under-inated.
