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.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 9‑41.
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.

Driving Characteristics
and Towing Tips
Pulling a Trailer
Here are some important points:
.There are many different laws,
including speed limit restrictions,
having to do with trailering.
Make sure the rig will be legal,
not only where you live but also
where you will be driving.
A good source for this
information can be state or
provincial police.
.Do not tow a trailer at all during
the first 1600 km (1,000 miles)
the new vehicle is driven. The
engine, transmission or other
parts could be damaged. The
repairs would not be covered by
the vehicle's warranty.
.Then, during the first 800 km
(500 miles) that a trailer is
towed, do not drive over 80 km/h
(50 mph) and do not make starts
at full throttle. This helps the
engine and other parts of
the vehicle wear in at the
heavier loads.
.Obey speed limit restrictions
when towing a trailer. Do not
drive faster than the maximum
posted speed for trailers, or no
more than 90 km/h (55 mph), to
save wear on the vehicle's parts.
.Do not tow a trailer when the
outside temperature is above
38°C (100°F).
Three important considerations
have to do with weight:
.the weight of the trailer,
.the weight of the trailer tongue
.and the total weight on the
vehicle's tires.

9-42 Driving and Operating
Driving with a Trailer
Towing a trailer requires a certain
amount of experience. Get to know
the rig before setting out for the
open road. Get acquainted with the
feel of handling and braking with the
added weight of the trailer. And
always keep in mind that the vehicle
you are driving is now longer and
not as responsive as the vehicle is
by itself.
Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirror adjustments. If the
trailer has electric brakes, start the
vehicle and trailer moving and then
apply the trailer brake controller by
hand to be sure the brakes are
working. This checks the electrical
connection at the same time.
During the trip, check occasionally
to be sure that the load is secure,
and that the lamps and any trailer
brakes are still working.
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
much farther beyond the passed
vehicle before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, 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. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer will not 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 the instrument panel
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.
When towing a trailer, the arrows
on the instrument panel flash for
turns even if the bulbs on the
trailer are burned out.

Black plate (43,1)Chevrolet Impala Owner Manual - 2011
Driving and Operating 9-43
For this reason you may think other
drivers are seeing the signal when
they are not. It is important to check
occasionally to be sure the trailer
bulbs are still working.
Driving on Grades
Notice:Do not tow on steep
continuous grades exceeding
9.6 km (6 miles). Extended, higher
than normal engine and
transmission temperatures may
result and damage the vehicle.
Frequent stops are very important
to allow the engine and
transmission to cool.
Reduce speed and shift to a
lower gear beforestarting 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.
On a long uphill grade, shift down
and reduce the vehicle's speed to
around 70 km/h (45 mph) to reduce
the possibility of the engine and the transmission overheating. If the
engine does overheat, see
Engine
Overheating on page 10‑19.
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
the transmission 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, and
.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
Scheduled Maintenance on
page 11‑2for more information.
Things that are especially important
in trailer operation are automatic
transmission fluid, engine oil, belts,
cooling system and brake system.
It is a good idea to 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. See Engine Overheating
on page 10‑19.
Changing a Tire When Trailer
Towing
If the vehicle gets a flat tire while
towing a trailer, be sure to secure
the trailer and disconnect it from the
vehicle before changing the tire.
Trailer Towing
{WARNING
The driver can lose control when
pulling a trailer if the correct
equipment is not used or the
vehicle is not driven properly.
For example, if the trailer is too
heavy, the brakes may not work
well —or even at all. The driver
and passengers could be
seriously injured. The vehicle may
also be damaged; the resulting
repairs would not be covered by
the vehicle warranty. Pull a trailer
only if all the steps in this section
have been followed.
(Continued)
WARNING (Continued)
Ask your dealer for advice and
information about towing a trailer
with the vehicle.
Notice: Pulling a trailer
improperly can damage the
vehicle and result in costly
repairs not covered by the
vehicle warranty. To pull a trailer
correctly, follow the advice in this
section and see your dealer for
important information about
towing a trailer with the vehicle.
The vehicle can tow a trailer if it is
equipped with the proper trailer
towing equipment. To identify the
trailering capacity of the vehicle,
read the information in “Weight of
the Trailer” that appears later in this
section. Trailering is different than
just driving the vehicle by itself.
Trailering means changes in
handling, acceleration, braking,
durability and fuel economy.

Black plate (45,1)Chevrolet Impala Owner Manual - 2011
Driving and Operating 9-45
Successful, safe trailering takes
correct equipment, and it has to be
used properly.
The following information has many
time-tested, important trailering tips
and safety rules. Many of these are
important for the safety of the
driver and the passengers. So
please read this section carefully
before pulling a trailer.
Load-pulling components such as
the engine, transmission, axles,
wheel assemblies and tires are
forced to work harder against the
drag of the added weight. The
engine is required to operate at
relatively higher speeds and under
greater loads, generating extra heat.
The trailer also adds considerably to
wind resistance, increasing the
pulling requirements.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 for more
information.
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 13‑4 for more information.
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.
If there are a lot of options,
equipment, passengers or
cargo in the vehicle, it will reduce
the tongue weight the vehicle can
carry, which will also reduce the
trailer weight the vehicle can tow.

Black plate (46,1)Chevrolet Impala Owner Manual - 2011
9-46 Driving and Operating
If towing a trailer, the tongue load
must be added to the GVW because
the vehicle will be carrying that
weight, too. SeeVehicle Load Limits
on page 9‑12 for more information
about the vehicle's maximum load
capacity.
Using a weight-carrying hitch, the
trailer tongue (A) should weigh 10 to
15 percent of the total loaded trailer
weight (B). After loading the trailer, weigh the
trailer and then the tongue,
separately, to see if the weights are
proper. If they are not, adjustments
might be made by moving some
items around in the trailer.
Total Weight on the
Vehicle's Tires
Be sure the vehicle's tires are
inflated to the upper limit for cold
tires. These numbers can be found
on the Certification/Tire label. See
Vehicle Load Limits on page 9‑12.
Make sure not to go over the GVW
limit for the vehicle, including the
weight of the trailer tongue.
Towing Equipment
Hitches
It is important to have the correct
hitch equipment. Crosswinds, large
trucks going by and rough roads are
a few reasons why the right hitch is
needed. Here are some rules to
follow:
.The rear bumper on the vehicle
is not intended for hitches. Do
not attach rental hitches or other
bumper-type hitches to it. Use
only a frame-mounted hitch that
does not attach to the bumper.
.Will any holes be made in the
body of the vehicle when the
trailer hitch is installed? If there
are, then be sure to seal the
holes later when the hitch is
removed. If the holes are not
sealed, dirt, water, and deadly
carbon monoxide (CO) from the
exhaust can get into the vehicle.
See
Engine Exhaust on
page 9‑24 in the Index for more
information.

Black plate (47,1)Chevrolet Impala Owner Manual - 2011
Driving and Operating 9-47
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the
tongue from contacting the road if it
becomes separated from the hitch.
Instructions about safety chains
may be provided by the hitch
manufacturer or by the trailer
manufacturer. Follow the
manufacturer's recommendation for
attaching safety chains and do not
attach them to the bumper. Always
leave just enough slack so the rig
can turn. Never allow safety chains
to drag on the ground.
Trailer Brakes
Because the vehicle has antilock
brakes, do not try to tap into the
vehicle's hydraulic brake system.
If you do, both brake systems will
not work well, or at all.
Does your trailer have its own
brakes? Be sure to read and follow
the instructions for the trailer brakes
so you will be able to install, adjust
and maintain them properly.
Conversions and
Add-Ons
Add-On Electrical
Equipment
Notice:Do not add anything
electrical to the vehicle unless
you check with your dealer first.
Some electrical equipment can
damage the vehicle and the
damage would not be covered by
the vehicle's warranty. Some
add-on electrical equipment can
keep other components from
working as they should.
Add-on equipment can drain the
vehicle's 12‐volt battery, even if
the vehicle is not operating.
The vehicle has an airbag system.
