2010 CHEVROLET SILVERADO cruise control

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 the vehicle speed.
When going downhill, you might have to brake or shift
to a lower gear to keep the vehicle speed down. When
the brakes are applied the cruise control is disengaged.
Ending Cruise Control
There are three ways to end cruise control:
.To disengage cruise control; step lightly on the
brake pedal.
.Press[on the steering wheel.
.To turn off the cruise control, pressIon the
steering wheel.
Erasing Speed Memory
The cruise control set speed is erased from memory by
pressing the
Ibutton or if the ignition is turned off.
Exterior Lamps
The exterior lamps control
is located on the
instrument panel to the
left of the steering wheel.
It controls the following systems:
.Headlamps
.Taillamps
.Parking Lamps
.License Plate Lamps
.Instrument Panel Lights
The exterior lamps control has four positions:
O(Off): Turns off the automatic headlamps and
daytime running lamps (DRL). Turn the headlamp
control to the off position again to turn the automatic
headlamps or DRL back on.
For vehicles first sold in Canada, the off position will
only work when the vehicle is shifted into P (Park).

StabiliTrak®System
The vehicle may have a vehicle stability enhancement
system called StabiliTrak. It is an advanced computer
controlled system that assists the driver with directional
control of the vehicle in difficult driving conditions.
StabiliTrak activates when the computer senses a
discrepancy between the intended path and the
direction the vehicle is actually traveling. StabiliTrak
selectively applies braking pressure at any one of the
vehicle's brakes to assist the driver with keeping the
vehicle on the intended path.
When the vehicle is started and begins to move, the
system performs several diagnostic checks to insure
there are no problems. The system may be heard or felt
while it is working. This is normal and does not mean
there is a problem with the vehicle. The system should
initialize before the vehicle reaches 20 mph (32 km/h).
In some cases, it may take approximately two miles of
driving before the system initializes.
If cruise control is being used when StabiliTrak
activates, the cruise control automatically disengages.
The cruise control can be re-engaged when road
conditions allow. SeeCruise Control
on page 4‑7for
more information. If the system fails to turn on or activate, the StabiliTrak
light along with one of the following messages will be
displayed on the Driver Information Center (DIC):
TRACTION CONTROL OFF, SERVICE TRACTION
CONTROL, STABILITRAK OFF, SERVICE
STABILITRAK. If these DIC messages appear, make
sure the StabiliTrak system has not been turned off
using the StabiliTrak on/off button. Then turn the
steering wheel clockwise from the nine o'clock position
to the three o'clock position. If this clears the
message(s), the vehicle does not need servicing. If this
does not clear the message(s), then turn the vehicle off,
wait 15 seconds, and then turn it back on again to reset
the system. If any of these messages still appear on the
DIC, the vehicle should be taken in for service. For
more information on the DIC messages, see
DIC
Warnings and Messages on page 4‑63.
The StabiliTrak light will
flash on the instrument
panel cluster when the
system is both on and
activated.
The system may be heard or felt while it is working; this
is normal.

In this mode, engine power is not reduced automatically
and the driven wheels can spin more freely. This can
cause the brake-traction control to activate constantly.
Notice:If the wheel(s) of one axle is allowed to spin
excessively while the StabiliTrak, ABS and brake
warning lights and any relevant DIC messages are
displayed, the transfer case could be damaged. The
repairs would not be covered by the vehicle
warranty. Reduce engine power and do not spin the
wheel(s) excessively while these lights and
messages are displayed.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens, a reduction in
acceleration may be noticed, or a noise or vibration may
be heard. This is normal.
If cruise control is being used when the system
activates, the StabiliTrak light will flash and cruise
control will automatically disengage. Cruise control may
be reengaged when road conditions allow. See Cruise
Control on page 4‑7.
StabiliTrak may also turn off automatically if it
determines that a problem exists with the system. If the
problem does not clear itself after restarting the vehicle,
see your dealer for service.Locking Rear Axle
Vehicles with a locking rear axle can give more traction
on snow, mud, ice, sand or gravel. It works like a
standard axle most of the time, but when traction is low,
this feature will allow the rear wheel with the most
traction to move the vehicle.
Steering
Power Steering
If the vehicle is a Two‐mode Hybrid, see the Two‐mode
Hybrid manual for more information.
If power steering assist is lost because the engine stops
or the system is not functioning, the vehicle can be
steered but it will take more effort.
Steering Tips
It is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and vehicle speed. While in a curve, speed is
the one factor that can be controlled.
If there is a need to reduce speed, do it before entering
the curve, while the front wheels are straight.

Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle's tires so they actually ride on the water.
This can happen if the road is wet enough and you are
going fast enough. When your vehicle is hydroplaning, it
has little or no contact with the road.
There is no hard and fast rule about hydroplaning. The
best advice is to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather driving tips
include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in good shape.
.Keep the windshield washer fluid reservoir filled.
.Have good tires with proper tread depth. SeeTireson page 6‑64.
.Turn off cruise control.
Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer before departing. Things to check on your own include:
.Windshield Washer Fluid:
Reservoir full? Windows
clean —inside and outside?
.Wiper Blades: In good shape?
.Fuel, Engine Oil, Other Fluids: All levels checked?
.Lamps:Do they all work and are lenses clean?
.Tires:Are treads good? Are tires inflated to
recommended pressure?
.Weather and Maps: Safe to travel? Have
up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, find a safe
place to park your vehicle and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.
.Keep your eyes moving —scan the road ahead
and to the sides.
.Check the rearview mirror and vehicle instruments
often.

Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow or ice between the
tires and the road, creating less traction or grip. Wet ice
can occur at about 0°C (32°F) when freezing rain
begins to fall, resulting in even less traction. Avoid
driving on wet ice or in freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the condition. Accelerate
gently so traction is not lost. Accelerating too quickly
causes the wheels to spin and makes the surface under
the tires slick, so there is even less traction.
Try not to break the fragile traction. If you accelerate too
fast, the drive wheels will spin and polish the surface
under the tires even more.The
StabiliTrak
®Systemon page 5‑6improves the
ability to accelerate on slippery roads, but slow down
and adjust your driving to the road conditions. When
driving through deep snow, turn off the traction control
part of the StabiliTrak
®System to help maintain vehicle
motion at lower speeds.
The Antilock Brake System (ABS)
on page 5‑4improves vehicle stability during hard stops on slippery
roads, but apply the brakes sooner than when on dry
pavement.
Allow greater following distance on any slippery road
and watch for slippery spots. Icy patches can occur on
otherwise clear roads in shaded areas. The surface of a
curve or an overpass can remain icy when the
surrounding roads are clear. Avoid sudden steering
maneuvers and braking while on ice.
Turn off cruise control, if equipped, on slippery surfaces.
