cruise control CHEVROLET SILVERADO 2007 1.G Owners Manual

Adjustable Throttle and Brake Pedal
If your vehicle has this feature, you can change
the position of the throttle and brake pedals.
This feature is designed for shorter drivers, since
the pedals cannot move farther away from the
standard position, but can move toward the driver
for better pedal reach.
The switch used to
adjust the pedals is
located on the
instrument panel below
the climate control
system.
Press the arrow at the bottom of the switch to
move the pedals closer to your body. Press
the arrow at the top of the switch to move the
pedals away from your body.Before you start driving, fully press the brake
pedal to conrm the adjustment is right for you.
While driving, make only small adjustments.
No adjustment to the pedals can be made when
the vehicle is in REVERSE (R) or while using
the cruise control.
Your vehicle may have a memory function which
allows pedal settings to be saved and recalled.
SeeMemory Seat, Mirrors, and Pedals on page 13
for more information.
Engine Coolant Heater
Your vehicle may have an engine coolant heater.
If your vehicle has the DURAMAX
®Diesel
engine, see the DURAMAX®Diesel manual for
more information.
In very cold weather, 0°F (−18°C) or colder, the
engine coolant heater can help. You will get easier
starting and better fuel economy during engine
warm-up.

Grade Braking is not available when the Range
Selection Mode is active. SeeTow/Haul Mode on
page 146
While using the Range Selection mode feature,
cruise control and the Tow/Haul mode can
be used.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the
transmission. The repair will not be covered by
your warranty. If you are stuck, do not spin
the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
Low Traction Mode
If your vehicle has the Allison Transmission®,or
the Hydra-Matic®6-Speed Automatic
Transmission, it has a Low Traction Mode that
assist in vehicle acceleration when road conditions
are slippery, such as with ice or snow. While
the vehicle is at a stop, select the second gear
range using the Range Selection system. This will
limit torque to the wheels after it detects wheel
slip, preventing the tires from spinning.
Tow/Haul Mode
If your vehicle has an automatic transmission, it
has a tow/haul mode. If your vehicle has an Allison
or Hydra-Matic
®6-speed automatic transmission
see “Tow/Haul Mode (Allison or Hydra-Matic®
6-Speed Automatic Transmission®) following.
146

Turn the tow/haul mode on and off by pressing the
button, located on the end of the shift lever.
When the tow/haul is on, a light on the instrument
panel cluster will come on.
SeeTow/Haul Mode Light on page 268for more
information.
Also see “Tow Haul Mode” underTowing a Trailer
on page 447for more information.
Grade Braking (Allison Transmission®
or Hydra-Matic®6-Speed Automatic
Transmission)
The Grade Braking shift modes can be activated
by pressing the button on the end of the shift
control lever. While in Range Selection Mode,
Grade Braking is deactivated allowing the driver to
select a desired range of gears.Grade Braking is only active while the Tow/Haul
Mode is selected and you are not in the Range
Selection Mode. See “Tow/Haul Mode listed
previously andAutomatic Transmission Operation
on page 140for more information on the Range
Slection Mode. Grade Braking assists in
maintaining desired vehicle speeds when driving
on downhill grades by automatically implementing
a shift schedule that utilizes the engine and
transmission to slow the vehicle. This reduces
wear on the braking system and increases control
of the vehicle. Grade Braking monitors vehicle
speed, acceleration, engine torque and brake
pedal usage. Using this information, it detects
when the truck is on a downhill grade and
the driver desires to slow the vehicle by pressing
the brake. See the diesel supplement for
information on Cruise Grade Braking.
Also seeTowing a Trailer on page 447for more
information.

Cruise Control
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
With cruise control, you can maintain a speed of
about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can
really help on long trips. Cruise control does not
work at speeds below about 25 mph (40 km/h).
When you apply your brakes, cruise control
is turned off.If your vehicle has an Allison
®automatic
transmission, see “Grade Braking and Cruise
Grade Braking (Allison Transmission
®) under
Tow/Haul Mode on page 146for an explanation of
how cruise control interacts with the Range
Selection Mode, tow/haul and grade braking
systems.
If your vehicle has the StabiliTrak
®™ system and
begins to limit wheel spin while you are using
cruise control, the cruise control will automatically
disengage. SeeStabiliTrak
®System on
page 384. When road conditions allow you to
safely use it again, you may turn the cruise control
back on.
The cruise control
buttons are located on
left side of the
steering wheel.
220

T(On/Off):This button can both activate and
turn off the system. The indicator light is on
when cruise control is on and turns off when cruise
control is off.
+ RES (Resume/Accelerate):Press this button
to make the vehicle accelerate or resume to
a previously set speed.
SET−(Set/Coast):Press this button to set the
speed or make the vehicle decelerate.
[(Cancel):Press this button to cancel cruise
control without erasing the set speed from
memory.
Setting Cruise Control
Cruise control will not work if the parking brake
is set, or if the master cylinder brake uid level
is low.
The cruise control light on the instrument panel
cluster will come on after the cruise control
has been set to the desired speed.
{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do not
want to. You could be startled and even
lose control. Keep the cruise control switch
off until you want to use cruise control.
1. Press the cruise control On/Off button.
2. Get up to the desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose you set the cruise control at a desired
speed and then you apply the brake. This shuts off
the cruise control. But you do not need to reset it.
Once you are driving about 25 mph (40 km/h) or
more, press the +RES button on the steering
wheel. The vehicle will go back to the previous set
speed and stay there.
221

Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise
control:
Press and hold the +RES button on the
steering wheel until you reach your new
desired speed, then release it.
To increase vehicle speed in small increments,
press the +RES button. Each time this is
done, the vehicle will go about 1 mph
(1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
To reduce the vehicle speed while using cruise
control:
Press and hold the SET– button on the
steering wheel until the desired lower speed is
reached, then release it.
To slow down in very small amounts, press
the SET– button on the steering wheel
briey. Each time this is done, the vehicle will
go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle
speed. When you take your foot off the pedal,
the vehicle will slow down to the previous
set cruise speed.
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’s speed. When going
downhill, you might have to brake or shift to a
lower gear to keep the vehicle’s speed down. Of
course, applying the brake turns off the cruise
control. Many drivers nd this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the cancel button on the steering wheel.
Press the On/Off button on the
steering wheel.
