2007 CHEVROLET IMPALA cruise control

Traction Control System (TCS)
Your vehicle may have a traction control system
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 ash
when your traction
control system is
limiting wheel spin.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the
traction control system begins to limit wheel spin,
the cruise control will automatically disengage.
When road conditions allow you to safely
use it again, you may re-engage the cruise
control. SeeCruise Control on page 157.The traction control system operates in all
transmission shift lever positions. But the system
can upshift the transmission only as high as
the shift lever position you’ve chosen, so you
should use the lower gears only when necessary.
SeeAutomatic Transaxle Operation on page 116.
When the system is on,
this warning light will
come on and stay on to
let you know if there’s
a problem.
A SERVICE TRACTION CONTROL message will
also appear on the DIC. When this warning
light is on, the system will not limit wheel spin.
Adjust your driving accordingly. SeeDIC Warnings
and Messages on page 199for more information.
To limit wheel spin, especially in slippery road
conditions, you should always leave the traction
control system on. But you can turn the system off
if you ever need to. You should turn the system
off if your vehicle ever gets stuck in sand, mud or
snow and rocking the vehicle is required.

(f)Lubricate all key lock cylinders. Lubricate
all hinges and latches, including those for the body
doors, hood, secondary latch, pivots, spring
anchor, release pawl, rear compartment, glove
box door, console door, and any folding seat
hardware. More frequent lubrication may
be required when exposed to a corrosive
environment. Applying silicone grease on
weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.
(g)If you drive regularly under dusty conditions,
the lter may require replacement more often.
(h)Change automatic transmission uid and lter
if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.(i)Drain, ush, and rell cooling system.
This service can be complex; you should have
your dealer/retailer perform this service. See
Engine Coolant on page 320for what to use.
Inspect hoses. Clean radiator, condenser, pressure
cap, and ller neck. Pressure test the cooling
system and pressure cap.
(j)Check throttle system for interference or
binding and for damaged or missing parts. Replace
parts as needed. Replace any components that
have high effort or excessive wear. Do not
lubricate accelerator or cruise control cables.
(k)A uid loss in any vehicle system could indicate
a problem. Have the system inspected and repaired
and the uid level checked. Add uid if needed.
(m)If you drive regularly under dusty conditions,
inspect the lter at each engine oil change.
(n)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
