2007 CHEVROLET IMPALA four wheel drive

SERVICE TIRE MONITOR SYSTEM
This message displays if a part on the Tire
Pressure Monitor (TPM) system is not working
properly. If you drive your vehicle while any of the
four sensors are missing or inoperable, the warning
comes on in about 20 minutes. A sensor would be
missing, for example, if you put different wheels on
your vehicle without transferring the sensors. If the
warning comes on and stays on, there may be a
problem with the TPM. See your dealer.
SERVICE TRACTION CONTROL
If your vehicle has the Traction Control System
(TCS), this message displays when the system is
not functioning properly. A warning light also
appears on the instrument panel cluster. See
Traction Control System (TCS) Warning Light on
page 183. SeeTraction Control System (TCS) on
page 256for more information. Have the TCS
serviced by your dealer as soon as possible.
SERVICE TRANSMISSION
This message displays when there is a problem
with the transaxle. See your dealer for service.
SERVICE VEHICLE SOON
This message displays when a non-emissions
related malfunction occurs. Have the vehicle
serviced by your dealer as soon as possible.
STARTING DISABLED SERVICE
THROTTLE
This message displays if the starting of the engine
is disabled due to the electronic throttle control
system. Have your vehicle serviced by your dealer
immediately.
This message only appears while the ignition is in
RUN, and will not disappear until the problem
is resolved.
This message cannot be acknowledged.
THEFT ATTEMPTED
This message displays if the content theft-deterrent
system has detected a break-in attempt while
you were away from your vehicle. SeeContent
Theft-Deterrent on page 107for more information.

The traction you can get in a curve depends on
the condition of the tires and the road surface, the
angle at which the curve is banked, and your
speed. While you are in a curve, speed is the
one factor you can control.
Suppose you are steering through a sharp curve.
Then you suddenly apply the brakes. Both
control systems — steering and braking — have
to do their work where the tires meet the road.
Unless you have four-wheel anti-lock brakes,
adding the hard braking can demand too much of
those places. You can lose control.
The same thing can happen if you are steering
through a sharp curve and you suddenly
accelerate. Those two control systems — steering
and acceleration — can overwhelm those
places where the tires meet the road and make
you lose control.What should you do if this ever happens? Ease up
on the brake or accelerator pedal, steer the
vehicle the way you want it to go, and slow down.
Speed limit signs near curves warn that you
should adjust your speed. Of course, the posted
speeds are based on good weather and road
conditions. Under less favorable conditions you will
want to go slower.
If you need to reduce your speed as you approach
a curve, do it before you enter the curve, while
the front wheels are straight ahead.
Try to adjust your speed so you can “drive”
through the curve. Maintain a reasonable, steady
speed. Wait to accelerate until you are out of
the curve, and then accelerate gently into
the straightaway.
Adding non-dealer/non-retailer accessories can
affect your vehicle’s performance. SeeAccessories
and Modications on page 296.

With the proper preparation and equipment, many
vehicles can be towed in these ways. See
“Dinghy Towing” and “Dolly Towing,” following.
Here are some important things to consider before
you do recreational vehicle towing:
What’s the towing capacity of the towing
vehicle? Be sure you read the tow vehicle
manufacturer’s recommendations.
How far will you tow? Some vehicles have
restrictions on how far and how long they
can tow.
Do you have the proper towing equipment?
See your dealer/retailer or trailering
professional for additional advice and
equipment recommendations.
Is your vehicle ready to be towed? Just as
you would prepare your vehicle for a long
trip, you’ll want to make sure your vehicle is
prepared to be towed. SeeBefore Leaving on
a Long Trip on page 269.
Dinghy Towing
Notice:If you tow your vehicle with all
four wheels on the ground, the drivetrain
components could be damaged. The repairs
would not be covered by your warranty. Do not
tow your vehicle with all four wheels on the
ground.
Your vehicle was not designed to be towed with
all four wheels on the ground. If your vehicle must
be towed, you should use a dolly. See “Dolly
Towing” that follows for more information.

Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the
brake pads are worn and new pads are needed.
The sound can come and go or be heard all
the time your vehicle is moving, except when
you are pushing on the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
Notice:Continuing to drive with worn-out
brake pads could result in costly brake repair.Some driving conditions or climates can cause a
brake squeal when the brakes are rst applied
or lightly applied. This does not mean something
is wrong with the brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated,
inspect brake pads for wear and evenly tighten
wheel nuts in the proper sequence to torque
specications inCapacities and Specications on
page 403.
Brake linings should always be replaced as
complete axle sets.Brake Pedal Travel
See your dealer/retailer if the brake pedal does
not return to normal height, or if there is a
rapid increase in pedal travel. This could be
a sign that brake service might be required.
Brake Adjustment
Every time you apply the brakes, with or without
the vehicle moving, the brakes adjust for wear.

7. Proceed to the passenger’s side front tire, and
repeat the procedure in Step 6.
8. Proceed to the passenger’s side rear tire, and
repeat the procedure in Step 6.
9. Proceed to the driver’s side rear tire, and
repeat the procedure in Step 6.
10. After hearing the conrming horn chirp for the
driver’s side rear tire, the tire learning process
ends. Turn the ignition switch to OFF.
11. Set all four tires to the recommended air
pressure level as indicated on the Tire
and Loading Information label.

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment.
Also check for damaged tires or wheels. SeeWhen
It Is Time for New Tires on page 366andWheel
Replacement on page 371for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 408for scheduled rotation
intervals.
