Repeat this until help arrives
but only when you feel really
uncomfortable from the cold.
Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
If the Vehicle is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If the vehicle has a traction
system, it can often help to free
a stuck vehicle. Refer to the
vehicle's traction system in theIndex. If stuck too severely for the
traction system to free the vehicle,
turn the traction system off and use
the rocking method.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 55 km/h (35 mph) as
shown on the speedometer.
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑58.
Rocking the Vehicle to
Get it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction or
stability system. Shift back and forth
between R (Reverse) and a forward
gear, spinning the wheels as little as
possible. To prevent transmission
wear, wait until the wheels stop
spinning before shifting gears.
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. If the vehicle
does need to be towed out, see
Towing the Vehicle on page 10‑74.

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.

Steps for Determining Correct
Load Limit
1.
Locate the statement
“The combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs”on your vehicle's
placard.
2.Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from XXX kg or
XXX lbs.
4.The resulting figure equals
the available amount of cargo
and luggage load capacity.
For example, if the “XXX”
amount equals 1400 lbs and
there will be five 150 lb
passengers in your vehicle,
the amount of available cargo and luggage load capacity is
650 lbs (1400
−750 (5 x 150)
= 650 lbs).
5.Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step³4.
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 for
your vehicle.
If your vehicle can tow a trailer,
see Trailer Towing on page 9‑44
for important information on
towing a trailer, towing safety
rules, and trailering tips.Example 1
A. Maximum Vehicle Capacity Weight for Example 1 =
453 kg (1,000 lbs)
B. Subtract Occupant Weight @ 68 kg (150 lbs) × 2 =
136 kg (300 lbs)
C. Available Occupant and Cargo Weight = 317 kg (700 lbs)

Example 2
A. Maximum Vehicle Capacity Weight for Example 2 =
453 kg (1,000 lbs)
B. Subtract Occupant Weight @ 68 kg (150 lbs) × 5 =
340 kg (750 lbs)
C. Available Cargo Weight = 113 kg (250 lbs)Example 3
A. Maximum Vehicle Capacity Weight for Example 3 =
453 kg (1,000 lbs)
B. Subtract Occupant Weight @ 91 kg (200 lbs) × 5 =
453 kg (1,000 lbs)
C. Available Cargo Weight = 0 kg (0 lbs)
Refer to your vehicle's Tire and
Loading Information label for
specific information about your
vehicle's maximum vehicle
capacity weight and seating positions. The combined weight
of the driver, passengers, and
cargo should never exceed your
vehicle's maximum vehicle
capacity weight.
Certification Label
A vehicle-specific Certification
label is found on the rear edge
of the driver door.
The label shows the gross
weight capacity of your vehicle,
called the Gross Vehicle Weight
Rating (GVWR).

Black plate (15,1)Chevrolet Impala Owner Manual - 2011
Driving and Operating 9-15
The GVWR includes the weight
of the vehicle, all occupants,
fuel, and cargo.
Never exceed the GVWR for
your vehicle or the Gross Axle
Weight Rating (GAWR) for either
the front or rear axle.
If there is a heavy load, it should
be spread out.
{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. Notice :
Overloading the
vehicle may cause damage.
Repairs would not be covered
by the vehicle warranty.
Do not overload the vehicle.
If things like suitcases, tools,
packages, or anything else are
put inside the vehicle, they will
go as fast as the vehicle goes.
If you have to stop or turn
quickly, or if there is a crash,
they will keep going.
{WARNING
Things you put inside the
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
.Put things in the cargo
area of the vehicle. In the
cargo area, put them as
(Continued)
WARNING (Continued)
far forward as you can.
Try to spread the weight
evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
.Do not leave an
unsecured child restraint
in the vehicle.
.When you carry something
inside the vehicle, secure
it whenever you can.
.Do not leave a seat folded
down unless you need to.

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.

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.
