Driving Information
Defensive Driving
Defensive driving means “always
expect the unexpected.” The first
step in driving defensively is to wear
your safety belt. See Safety Belts on
page 3‑12.
{WARNING
Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
In addition:
.Allow enough following
distance between you and
the driver in front of you.
.Focus on the task of driving.
(Continued)
WARNING (Continued)
Driver distraction can cause
collisions resulting in injury or
possible death. These simple
defensive driving techniques
could save your life.
Drunk Driving
{WARNING
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious —or even
fatal —collision if you drive after
drinking. Do not drink and drive or
ride with a driver who has been
drinking. Ride home in a cab; or if
you are with a group, designate a
driver who will not drink.

Black plate (23,1)Chevrolet Avalanche Owner Manual - 2011
Driving and Operating 9-23
Release the accelerator pedal while
shifting, and press lightly on the
accelerator pedal when the
transmission is in gear. Slowly
spinning the wheels in the forward
and reverse directions causes a
rocking motion that could free the
vehicle. If that does not get the
vehicle out after a few tries, it might
need to be towed out. Recovery
hooks can be used, if the vehicle
has them. If the vehicle does need
to be towed out, seeTowing the
Vehicle on page 10‑93.Recovery Hooks
{WARNING
These hooks, when used, are
under a lot of force. Always pull
the vehicle straight out. Never pull
on the hooks at a sideways angle.
The hooks could break off and
you or others could be injured
from the chain or cable
snapping back.
Notice: Never use recovery
hooks to tow the vehicle. Your
vehicle could be damaged and it
would not be covered by
warranty.
The recovery hooks at the front of
the vehicle can be used if the
vehicle is stuck off-road and needs
to be pulled to some place where
you can continue driving.

6.If your vehicle will be towing
a trailer, the load from your
trailer will be transferred to
your vehicle. Consult this
manual to determine how this
reduces the available cargo
and luggage load capacity of
your vehicle. SeeTrailer
Towing on page 9‑79 for
important information on
towing a trailer, towing safety
rules and trailering tips.

New Vehicle Break-In
Notice:The vehicle does not
need an elaborate break-in. But it
will perform better in the long run
if you follow these guidelines:
.Keep your speed at
88 km/h (55 mph) or less for
the first 805 km (500 miles).
.Do not drive at any one
constant speed, fast or
slow, for the first 805 km
(500 miles). Do not make
full-throttle starts. Avoid
downshifting to brake or
slow the vehicle.
.Avoid making hard stops for
the first 322 km (200 miles) or
so. During this time the new
brake linings are not yet
broken in. Hard stops with
new linings can mean
premature wear and earlier
replacement. Follow this breaking-in
guideline every time you get
new brake linings.
.Do not tow a trailer during
break-in. See
Trailer Towing
on page 9‑79 for the trailer
towing capabilities of the
vehicle and more
information.
Following break‐in, engine speed
and load can be gradually
increased.
Adjustable Throttle and
Brake Pedal
On vehicles with this feature, you
can change the position of the
throttle and brake pedals.
No adjustment to the pedals can
be made when the vehicle is in
R (Reverse) or while using cruise
control.
The control used to adjust the
pedals is located on the instrument
panel below the climate control
system.
Press the bottom of the control to
move the pedals closer. Press the
top of the control to move the
pedals away.
Before you start driving, fully press
the brake pedal to confirm the
adjustment is right for you.
While driving, make only small
adjustments.
The vehicle may have a memory
function which lets pedal settings be
saved and recalled. See Power
Seat Adjustment on page 3‑4 for
more information.

9-32 Driving and Operating
B (ACC/ACCESSORY):This
position lets things like the radio
and the windshield wipers operate
while the engine is off. Use this
position if the vehicle must be
pushed or towed.
C (ON/RUN): This position can be
used to operate the electrical
accessories and to display some
instrument panel cluster warning
and indicator lights. The switch
stays in this position when the
engine is running. The transmission
is also unlocked in this position on
automatic transmission vehicles.
If you leave the key in the ACC/
ACCESSORY or ON/RUN position
with the engine off, the battery could
be drained. You may not be able to
start the vehicle if the battery is
allowed to drain for an extended
period of time. D (START):
This is the position that
starts the engine. When the engine
starts, release the key. The ignition
switch returns to ON/RUN for
driving.
A warning tone will sound when
the driver door is opened and the
ignition is in ACC/ACCESSORY or
LOCK/OFF, and the key is in the
ignition.
Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only.
Notice: Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn the ignition to START.
When the engine starts, let go of
the key. The idle speed will slow
down as the engine warms. Do
not race the engine immediately
after starting it. Operate the
engine and transmission gently
to allow the oil to warm up and
lubricate all moving parts.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking for
a few seconds or until the
vehicle starts. If the engine does
not start and the key is held in
START, cranking will be
stopped after 15 seconds to
prevent cranking motor damage.

Shifting Into Park
{WARNING
It can be dangerous to get out of
the vehicle if the shift lever is not
fully in P (Park) with the parking
brake firmly set. The vehicle can
roll. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when you are on
fairly level ground, use the steps
that follow. If you have a
four-wheel drive transfer case
with a N (Neutral) position, and
the transfer case is in N (Neutral),
the vehicle will be free to roll,
even if the shift lever is in
P (Park). So, be sure the transfer
case is in a drive gear—not in
N (Neutral). If you are pulling a
trailer, see Driving Characteristics
and Towing Tips on page 9‑75.
Always set the parking brake. 1. Hold the brake pedal down,
then set the parking brake.
See Parking Brake on page 9‑53
for more information.
2. Move the shift lever into the P (Park) position by pulling the
shift lever toward you and
moving it up as far as it will go.
3. Be sure the transfer case is in a drive gear —not in N (Neutral).
4. Turn the ignition key to LOCK/OFF.
5. Remove the key and take it with you. If you can leave the vehicle
with the ignition key in your
hand, the vehicle is in P (Park).
Leaving the Vehicle With the
Engine Running
{WARNING
It can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
(Continued)
WARNING (Continued)
if the shift lever is not fully in
P (Park) with the parking brake
firmly set.
If you have four-wheel drive and
the transfer case is in N (Neutral),
the vehicle will be free to roll,
even if the shift lever is in
P (Park). So be sure the transfer
case is in a drive gear —not in
N (Neutral).
And, if you leave the vehicle
with the engine running, it could
overheat and even catch fire. You
or others could be injured. Do not
leave the vehicle with the engine
running unless you have to.
If you have to leave the vehicle with
the engine running, be sure your
vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you move the shift
lever into P (Park), hold the regular
brake pedal down.

Black plate (36,1)Chevrolet Avalanche Owner Manual - 2011
9-36 Driving and Operating
Then, see if you can move the shift
lever away from P (Park) without
first pulling it toward you. If you can,
it means that the shift lever was not
fully locked into P (Park).
Torque Lock
If you are parking on a hill and
you do not shift your transmission
into P (Park) properly, the weight
of the vehicle may put too much
force on the parking pawl in the
transmission. You may find it difficult
to pull the shift lever out of P (Park).
This is called torque lock. To
prevent torque lock, set the parking
brake and then shift into P (Park)
properly before you leave the driver
seat. To find out how, seeShifting
Into Park on page 9‑35.
When you are ready to drive, move
the shift lever out of P (Park) before
you release the parking brake. If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of
the pressure from the parking pawl
in the transmission, then you will be
able to pull the shift lever out of
P (Park).
Shifting Out of Park
This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is
designed to:
.Prevent ignition key removal
unless the shift lever is in
P (Park) with the shift lever
button fully released.
.Prevent movement of the shift
lever out of P (Park), unless the
ignition is in ON/RUN or ACC/
ACCESSORY and the regular
brake pedal is applied.
The shift lock release is always
functional except in the case of an
uncharged or low voltage (less than
9 volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. See
Jump Starting on
page 10‑88 for more information.
To shift out of P (Park) use the
following:
1. Apply the brake pedal.
2. Move the shift lever to the desired position.

Automatic
Transmission
The vehicle has a
Hydra-Matic®6L80 automatic
transmission, and has an electronic
shift position indicator within the
instrument panel cluster. The
electronic shift position indicator
displays when the shift lever is
moved out of P (Park).
There are several different positions
for the shift lever.
See “Range Selection Mode” under
Manual Mode on page 9‑42.
P (Park): This position locks your
rear wheels. It is the best position to
use when you start the engine
because the vehicle cannot move
easily.

Black plate (40,1)Chevrolet Avalanche Owner Manual - 2011
9-40 Driving and Operating
When parked on a hill, especially
when the vehicle has a heavy load,
you may notice an increase in the
effort to shift out of P (Park). See
