the driving situation dictates. The
Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade sufficient enough to activate
HSA. This feature is designed to
prevent the vehicle from rolling,
either forward or rearward, during
vehicle drive off. After the driver
completely stops and holds the
vehicle in a complete standstill on a
grade, HSA will be automatically
activated. During the transition
period between when the driver
releases the brake pedal and starts
to accelerate to drive off on a grade,
HSA holds the braking pressure for
a maximum of two seconds to
ensure that there is no rolling. The
brakes will automatically release
when the accelerator pedal is
applied within the two-secondwindow. It will not activate if the
vehicle is in a drive gear and facing
downhill, or if the vehicle is facing
uphill and in R (Reverse).
Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak, an
electronic stability control system.
These systems help limit wheel spin
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that any
of the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to
the spinning wheels and reduces
engine power to limit wheel spin.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any one of the

Chevrolet Colorado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11349743) - 2018 - crc - 10/12/17
Driving and Operating 241
vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
TCS or StabiliTrak begins to limit
wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
SeeIf the Vehicle Is Stuck 0209
and “Turning the Systems Off and
On” later in this section.
When the transfer case (if equipped)
is in 4
n, the stability system is
automatically disabled, and
g
comes on in the instrument cluster.
Both TCS and StabiliTrak are
automatically disabled.
The indicator light for both systems
is in the instrument cluster. This
light will:
. Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak is
activated.
. Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly. If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on
and stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.

calibrations are different while in
Off-Road Mode. They provide
optimum performance in an off-road
environment.
Pressing and releasing
gwhile in
Off-Road Mode disables TCS and
changes the StabiliTrak calibration
to allow a greater difference
between vehicle path and intended
path. This reduces the amount of correction StabiliTrak will provide in
the event the vehicle is not traveling
on the intended path.

Hill Descent
Control (HDC)
If equipped, HDC can be used when
driving downhill. It sets and
maintains vehicle speed while
descending a very steep incline in a
forward or reverse gear.
The HDC switch is on the center
stack, below the climate controls. Press
5to enable or disable HDC.
Vehicle speed must be below
60 km/h (37 mph).
The HDC light displays on the
instrument cluster when enabled.
HDC can maintain vehicle speeds
between 4 and 30 km/h (3 and
19 mph) on an incline greater than
or equal to a 10% grade. A blinking
HDC light indicates that the system
is actively applying the brakes to
maintain vehicle speed.
When HDC is set, that is the initial
set speed. It can be increased or
decreased by applying the
accelerator or brake pedal. Smaller
HDC speed control adjustments are
accomplished using the cruise up or
down buttons. Each tap of the
+RES will increase the set speed by
0.8 km/h (0.5 mph), while each tap

of the SET–will decrease the set
speed by 0.8 km/h (0.5 mph). This
adjusted speed becomes the new
set speed.
HDC will remain enabled between
30 and 60 km/h (19 and 37 mph),
however vehicle speed cannot be
set or maintained in this range.
It will automatically disable if the
vehicle speed is above 80 km/h
(50 mph) or above 60 km/h

driver to reduce speed for HDC
operation.
Cruise control will not function while
HDC is enabled and vehicle speed
is below 40 km/h (25 mph).
Driver Mode Control
(ZR2 Only)
If equipped, the Off-Road Driving
Mode attempts to maximize
performance on terrain with limited
traction. It is turned on by pressing
and releasing
7on the center of
the transfer case knob located on
the instrument panel. The Off-Road
Mode is accessible in all transfer
case modes and is turned off
automatically when the vehicle
ignition is turned off.
Transfer Case Knob with
Off-Road Mode
Off-Road Mode facilitates limited
traction driving by:
. Modifying the sensitivity of the
accelerator pedal for fine linear
control of torque on uneven
terrain
. Modifying the transmission shift
map to hold gears for longer, in
order to limit slip while driving
over obstacles

Off-Road Mode also interact with
the axle locking system. It allows
the vehicle to travel at higher
speeds with a locked rear axle. See
Locking Rear Axle 0245 for more
information.
Limited-Slip Differential
If equipped, the limited-slip
differential 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 allows the drive wheel
with the most traction to move the
vehicle. For vehicles with the
limited-slip differential, driven under severe conditions, the rear axle fluid
should be changed. See
Maintenance Schedule
0365.
Locking Rear Axle
If equipped, the locking rear axle
can give the vehicle additional
traction from the rear wheels when
traveling in off-road situations such
as mud, snow, steep hills, and
uneven terrain.
Caution
If you try to lock the axle while the
vehicle is stuck and the tires are
spinning, the vehicle’ s drivetrain
could be damaged. The repairs
would not be covered by the
vehicle warranty. Always lock the
axle before attempting situations
and/or navigating terrain that
could cause the vehicle to
become stuck.
Caution
If the vehicle’ s axle is locked
while driving on pavement, the
drivetrain could be damaged.
Repairs would not be covered by
the vehicle warranty. Do not use
the locking axle on pavement.
Before the front axle can be locked,
the rear axle must be locked and
the transfer case must be in 4
n.

246 Driving and Operating
To lock the rear axle:1. Press the rear axle locking switch with the vehicle moving
less than 40 km/h (25 mph).
2. Wait for the light in the switch to stop flashing and remain
illuminated to show that the
rear axle is locked.
The locking rear axle will be
disengaged when the vehicle speed
exceeds 40 km/h (25 mph). The
Off-Road Mode allows the axle lock
to remain engaged at higher vehicle
speeds.
After pressing the switch to unlock
the axle, it may remain locked due
to torque in the driveline. The axle is
more easily unlocked by turning the
steering wheel to the right and to
the left while traveling at a low
speed.
Locking Front Axle
If equipped, the locking front axle
can give the vehicle additional
traction when traveling in off-road
situations such as mud, snow, steep
hills, and uneven terrain.
Caution
If you try to lock the axle while the
vehicle is stuck and the tires are
spinning, the vehicle’ s drivetrain
could be damaged. The repairs
would not be covered by the
vehicle warranty. Always lock the
axle before attempting situations
and/or navigating terrain that
could cause the vehicle to
become stuck.
Caution
If the vehicle’ s axle is locked
while driving on pavement, the
drivetrain could be damaged.
Repairs would not be covered by
the vehicle warranty. Do not use
the locking axle on pavement.
Before the front axle can be locked,
the rear axle must be locked and
the transfer case must be in 4
n.
To lock the front and rear axles:
1. Place the transfer case in 4
n.
This is the only mode that
allows the front axle to lock.
See Four-Wheel Drive 0231

Engagement of the front axle
lock will disable the Antilock
Brake System (ABS) and
illuminate the ABS warning
light. Hill Decent Control (HDC)
will also be disabled.
The locking front axle will be
disengaged when the vehicle speed
exceeds 40 km/h (25 mph) or the
transfer case is shifted out of 4
n.
ABS will be automatically enabled
and the ABS warning light will turn
off when the locking front axle is
disengaged. If HDC was enabled prior to axle
lock, it will be automatically enabled
when the locking front axle is
disengaged.
After pressing the switch to unlock
the axle, it may remain locked due
to torque in the driveline. The axle is
more easily unlocked by turning the
steering wheel to the right and to
the left while traveling at a low
speed.
Cruise Control
With cruise control a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
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.
If equipped with a manual
transmission, the cruise control will
remain active when the gears are
shifted. The cruise is deactivated if
the clutch is pressed for several
seconds. If the cruise control is
