9-22 Driving and Operating
{WARNING
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Notice: Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle. D (Drive):
This position is for
normal driving. It provides the best
fuel economy. If you need more
power for passing, and you are:
.Going less than 56 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 56 km/h (35 mph) or
more, push the accelerator all
the way down.
Notice: If the vehicle seems to
accelerate slowly or not shift
gears when you go faster, and
you continue to drive the vehicle
that way, you could damage the
transmission. Have the vehicle
serviced right away. You can
drive in L (Low) when you are
driving less than 56 km/h (35 mph)
and D (Drive) for higher speeds
until then.
Downshifting the transmission in
slippery road conditions could result
in skidding, see "Skidding" under
Loss of Control on page 9‑4. L (Low):
This position gives you
access to gear ranges. This
provides more engine braking but
lower fuel economy than D (Drive).
You can use it on very steep hills,
or in deep snow or mud. See the
following text on Manual Mode.Manual Mode
Electronic Range Select
(ERS) Mode
ERS mode allows you to choose the
top-gear limit of the transmission,
which can help control the vehicle's

Driving and Operating 9-23
speed while driving downhill or
towing a trailer. The vehicle has an
electronic shift position indicator
within the instrument cluster. When
using the ERS mode a number will
display next to the L, indicating the
current range that has been
selected.
To use this feature:
1. Move the shift lever to L (Low).
2. Press the + (Plus) or−(Minus)
button located on the left side of
the steering wheel, to increase
or decrease the gear range
available.
When you shift from D (Drive) to
L (Low), the transmission will shift to
a pre-determined lower gear range. The highest gear available for this
pre-determined range is displayed
next to the L in the DIC. The
number displayed in the DIC is the
highest gear that the transmission
will be allowed to operate in. All
gears below that number are
available. For example, when
4 (Fourth) is shown next to the L,
1 (First) through 4 (Fourth) gears are
automatically shifted by the vehicle.
The transmission will not shift into
5 (Fifth) until the + (Plus) button is
used or you shift back into D (Drive).
While in L (Low), the transmission
will prevent shifting to a lower gear
range if the engine speed is
too high.Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. See
Antilock
Brake System (ABS) Warning Light
on page 5‑18.

9-24 Driving and Operating
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Parking Brake
The parking brake is located to the
left of the brake pedal, near the
driver door.
To set the parking brake, hold the
brake pedal down, then push down
the parking brake pedal.
To release the parking brake, hold
the brake pedal down and push the
parking brake pedal. When you lift
your foot off the parking brake
pedal, the pedal will follow it to the
released position.

Black plate (25,1)Chevrolet Impala Owner Manual - 2013 - crc - 8/27/12
Driving and Operating 9-25
A warning chime will sound and a
brake warning light located on the
instrument panel cluster will come
on, if the parking brake is set, the
ignition is on, and the vehicle speed
is greater than 8 km/h (5 mph).
Notice:Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
If you are towing a trailer and
parking on any hill, see Driving
Characteristics and Towing Tips on
page 9‑36.Ride Control Systems
Traction Control
System (TCS)
The vehicle may have a Traction
Control System (TCS) that limits
wheel spin. This is especially useful
in slippery road conditions. The
system operates only if it senses
that one or both of the front wheels
are spinning or beginning to lose
traction. When this happens, the
system reduces engine power and
may also upshift the transmission
and apply the front brakes to limit
wheel spin.
This light will flash when the TCS is
limiting wheel spin. The system may be heard or felt
while it is working, but this is
normal.
If cruise control is being used when
TCS begins to limit wheel spin, the
cruise control will automatically
disengage. Cruise control may be
reengaged when road conditions
allow. See
Cruise Control on
page 9‑28.
The TCS operates in all
transmission shift lever positions.
But the system can upshift the
transmission only as high as the
shift lever position chosen, so use
the lower gears only when
necessary. See Automatic
Transmission on page 9‑20.

Black plate (26,1)Chevrolet Impala Owner Manual - 2013 - crc - 8/27/12
9-26 Driving and Operating
When the system is on, this warning
light comes on and stays on if there
is a problem.
A SERVICE TRACTION CONTROL
message also appears on the DIC.
When this warning light is on, the
system will not limit wheel spin.
Adjust your driving accordingly. See
Ride Control System Messages on
page 5‑30for more information.
To limit wheel spin, especially in
slippery road conditions, TCS
should always be left on. But the
system can be turned off if needed.
Turn the system off if the vehicle
gets stuck in sand, mud, or snow
and rocking the vehicle is required.
See If the Vehicle Is Stuck on
page 9‑8 for more information.To turn the system on or off, press
the ESC OFF button located on the
instrument panel.
When the system is turned off, the
TRACTION CONTROL OFF
message appears on the DIC. If the
traction control system is limiting
wheel spin when the button is
pressed to turn the system off, the
TRACTION CONTROL OFF
message will appear on the DIC and
the system will turn off right away.
Press the ESC OFF button again to
turn the system back on. The
TRACTION CONTROL ON
message will appear in the DIC.
Adding non‐dealer accessories can
affect the vehicle performance. See
Accessories and Modifications on
page 10‑3 for more information.
Electronic Stability
Control (ESC)
Your vehicle may have an Electronic
Stability Control (ESC) system
which combines antilock brake, traction, and stability control
systems and helps the driver
maintain directional control of the
vehicle in most driving conditions.
When you first start your vehicle
and begin to drive away, the system
performs several diagnostic checks
to ensure there are no problems.
You may hear or feel the system
working. This is normal and does
not mean there is a problem with
your vehicle. The system should
initialize before the vehicle reaches
32 km/h (20 mph).
If the system fails to turn on or
activate due to a fault, the ESC/TCS
light will be on solid, and the
SERVICE STABILITRAK message
will be displayed. If the system fails
to turn on or activate due to it not
initializing, the DIC will display
STABILITRAK INITIALIZING.
For more information, see
Ride
Control System Messages on
page 5‑30.

Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase vehicle speed. When you
take your foot off the pedal, the
vehicle will slow down to the cruise
speed you set earlier.
Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain your
speed. When going downhill, you
might have to brake or shift to a
lower gear to keep your speed
down. If the brakes are applied the
cruise control will turn off. Ending Cruise Control

Driving and Operating 9-37
Towing a trailer requires a certain
amount of experience. The
combination you are driving is
longer and not as responsive as the
vehicle itself. Get acquainted with
the handling and braking of the rig
before setting out for the open road.
Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirrors. If the trailer has
electric brakes, start the
combination moving and then apply
the trailer brake controller by hand
to be sure the brakes work.
During the trip, check occasionally
to be sure that the load is secure
and the lamps and any trailer
brakes still work.
Towing with a Stability Control
System
When towing, the sound of the
stability control system might be
heard. The system is reacting to the
vehicle movement caused by thetrailer, which mainly occurs during
cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid situations
that require heavy braking and
sudden turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
farther beyond the passed vehicle
before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. To move the
trailer to the left, move your 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. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal so the
trailer will not strike soft shoulders,
curbs, road signs, trees or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument cluster flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer
lamps also flash, telling other
drivers the vehicle is turning,
changing lanes or stopping.

9-38 Driving and Operating
When towing a trailer, the arrows on
the instrument cluster flash for turns
even if the bulbs on the trailer are
burned out. Check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
When towing at high altitude on
steep uphill grades, engine coolant
boils at a lower temperature than at
normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the vehicle could show
signs similar to engine overheating.To avoid this, let the engine run
while parked, preferably on level
ground, with the transmission in
P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating on page 10‑14.Parking on Hills
{WARNING
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if facing
downhill or into traffic if facing
uphill. 2. Have someone place chocks
under the trailer wheels.
3. When the wheel chocks are in place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
.Start the engine.
.Shift into a gear.
.Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.

Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See the
Maintenance Schedule on
page 11‑3. Things that are
especially important in trailer
operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system and
brake system. Inspect these before
and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. SeeEngine Overheating
on page 10‑14.
Trailer Towing
Before pulling a trailer, there are
three important considerations that
have to do with weight:
.The weight of the trailer.
.The weight of the trailer tongue.
.The total weight on your
vehicle's tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
454 kg (1,000 lbs). But even that
can be too heavy.
It depends on how the rig is used.
For example, speed, altitude, road
grades, outside temperature, and
how much the vehicle is used to pull
a trailer are all important. It can
depend on any special equipment
on the vehicle, and the amount of
tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue”
later in this section. Maximum trailer weight is calculated
assuming only the driver is in the
tow vehicle and it has all the
required trailering equipment. The
weight of additional optional
equipment, passengers, and cargo
in the tow vehicle must be
subtracted from the maximum trailer
weight.
Ask your dealer for trailering
information or advice, or write us at
our Customer Assistance Offices.
See
Customer Assistance Offices
on page 13‑3.
Weight of the Trailer Tongue
The tongue load (A) of any trailer is
an important weight to measure
because it affects the total gross
weight of the vehicle. The Gross
Vehicle Weight (GVW) includes the
curb weight of the vehicle, any
cargo carried in it, and the people
who will be riding in the vehicle.
