Blizzard Conditions
Being stuck in snow can be in a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program on page 13‑7.
To get help and keep everyone in
the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
Carbon Monoxide (CO) which
cannot be seen or smelled.
It can cause unconsciousness
and even death.
(Continued)
WARNING (Continued)
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about
5 cm (2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting.
See Climate Control System
in the Index.(Continued)
WARNING (Continued)
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑24.
Snow can trap exhaust
gases under your vehicle.
This can cause deadly
CO (Carbon Monoxide) gas to
get inside. CO could overcome
you and kill you. You cannot see
it or smell it, so you might not
know it is in your vehicle. Clear
away snow from around the base
of your vehicle, especially any
that is blocking the exhaust.
Run the engine for short periods
only as needed to keep warm, but
be careful.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the
engine off and close the window
most of the way to save heat.

Vehicle Load Limits
It is very important to know how
much weight your vehicle can
carry. Two labels on your vehicle
show how much weight it may
properly carry, the Tire and
Loading Information label and
the Vehicle Certification label.
{WARNING
Do not load the vehicle
any heavier than the
Gross Vehicle Weight
Rating (GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
If you do, parts on the vehicle
can break, and it can change
the way the vehicle handles.
These could cause you to
lose control and crash.
Also, overloading can shorten
the life of the vehicle.
Tire and Loading Information
Label
Label Example
A vehicle-specific Tire and
Loading Information label is
attached to the vehicle's center
pillar (B-pillar). With the driver
door open, you will find the
label attached below the
door lock post (striker). The
Tire and Loading Information
label lists the number of
occupant seating positions (A), and the maximum vehicle
capacity weight (B) in kilograms
and pounds. The vehicle
capacity weight includes the
weight of all occupants, cargo,
and all nonfactory‐installed
options.
The Tire and Loading
Information label also lists
the tire size of the original
equipment tires (C) and the
recommended cold tire inflation
pressures (D). For more
information on tires and inflation,
see
Tires on page 10‑38 and
Tire Pressure on page 10‑44 .
There is also important loading
information on the Certification
label. It tells you the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight
Rating (GAWR) for the front and
rear axle, see “Certification
Label” later in this section.

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:
.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 9‑44 for the trailer
towing capabilities of your
vehicle and more
information.
Following break‐in, engine speed
and load can be gradually
increased.
Ignition Positions
The ignition switch has four different
positions. To shift out of P (Park), the ignition
must be in ON/RUN and the brake
pedal must be applied.
Notice:
Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer.
A (STOPPING THE ENGINE/
LOCK/OFF): When the vehicle is
stopped, turn the ignition switch to
LOCK/OFF to turn the engine off.
Retained Accessory Power (RAP)
will remain active. See Retained
Accessory Power (RAP) on
page 9‑18
This position locks the ignition.
It also locks the transmission. This
is the only position in which the
ignition key can be inserted or
removed.

Driving and Operating 9-17
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
In an emergency:
1. Brake using a firm and steadypressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to neutral. This can be done while the vehicle is
moving. After shifting to neutral,
firmly apply the brakes and steer
the vehicle to a safe location. 3. Come to a complete stop, shift
to P (Park), and turn the ignition
to LOCK/OFF. On vehicles with
an automatic transmission, the
shift lever must be in P (Park) to
turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake on page 9‑29
The steering can bind with the
wheels turned off center. If this
happens, move the steering wheel
from left to right while turning the
key to ACC/ACCESSORY. If this
doesn't work, then the vehicle
needs service.
B (ACC/ACCESSORY): This is the
position in which you can operate
the radio and windshield wipers
while the engine is off. To use
ACC/ACCESSORY, turn the key
clockwise. 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.
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 chime will sound and the
Driver Information Center (DIC) will
display DRIVER DOOR OPEN
when the driver door is opened, the
ignition is in ACC/ACCESSORY or
LOCK/OFF, and the key is in the
ignition. See Door Ajar Messages
on page 5‑29 for more information.

Retained Accessory
Power (RAP)
These vehicle accessories can be
used for up to 10 minutes after the
engine turned off:
.Audio System
.Power Windows
The radio will work when the key is
in ON/RUN or ACC/ACCESSORY.
Once the key is turned from ON/
RUN to LOCK/OFF the radio will
continue to work 10 minutes or until
the driver door is opened. The
power windows will continue to work
for up to 10 minutes or until any
door is opened.
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. To
prevent gear damage, this
system also prevents cranking if
the engine is already running.
Engine cranking can be stopped
by turning the ignition switch to
the ACC/ACCESSORY or
LOCK/OFF position.

Black plate (22,1)Chevrolet Impala Owner Manual - 2011
9-22 Driving and Operating
Torque Lock
Torque lock is when the weight
of the vehicle puts too much force
on the parking pawl in the
transmission. This happens when
parking on a hill and shifting the
transmission into P (Park) is not
done properly and then it is difficult
to shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park). To find
out how, see“Shifting Into Park” in
this section.
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).
Shifting Out of Park
Automatic Transmission
Shift Lock
The vehicle has 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).
.Prevent movement of the shift
lever out of P (Park), unless the
ignition is in ON/RUN and the
regular brake pedal is applied.
The shift lock is always functional
except in the case of a 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 10‑70. Console Shift
If the console shift lever cannot be
moved out of P (Park):
1. Apply and maintain the regular
brakes.
2. Turn the ignition to ON/RUN position. See Ignition Positions
on page 9‑16 for more
information.
3. Let up on the shift lever and make sure the shift lever is
pushed all the way into P (Park).
4. Press the shift lever button.
5. Then, move the shift into the desired gear.
If you still cannot move the shift
lever from P (Park), consult your
dealer or a professional towing
service.
