Forward Collision Alert
(FCA) System
If equipped, FCA may help avoid or
reduce the harm caused by
front-end crashes. FCA provides a
green indicator,
V, when a vehicle
is detected ahead. This indicator
displays amber if you follow a
vehicle too closely. When
approaching a vehicle ahead too
quickly, FCA provides a flashing red
alert on the windshield and rapidly
beeps or pulses the driver seat.
See Forward Collision Alert (FCA)
System 0285.
Forward Automatic
Braking (FAB)
If the vehicle has Forward Collision
Alert (FCA), it also has FAB, which
includes Intelligent Brake
Assist (IBA). When the system detects a vehicle ahead in your path
that is traveling in the same
direction that you may be about to
crash into, it can provide a boost to
braking or automatically brake the
vehicle. This can help avoid or
lessen the severity of crashes when
driving in a forward gear.
See
Forward Automatic Braking
(FAB) 0287.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
unintentional lane departures at
speeds of 56 km/h (35 mph) or
greater. LDW uses a camera sensor
to detect the lane markings. The
LDW light,
@, is green if a lane
marking is detected. If the vehicle
departs the lane, the light will
change to amber and flash. In
addition, beeps will sound or the
driver seat will pulse.
See Lane Departure Warning (LDW)
(2500/3500 Series) 0288.

Performance and
Maintenance
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) that limits wheel spin
and the StabiliTrak system that
assists with directional control of the
vehicle in difficult driving conditions.
Both systems come on
automatically when the vehicle is
started and begins to move.
.
To turn off TCS, press and
release
gon the center stack.
The traction off light
idisplays

StabiliTrak, press and hold
g
untiliandgilluminate in the
instrument cluster and the
appropriate DIC message
displays. .
Press and release
gagain to
turn on both systems.
StabiliTrak will automatically turn on
if the vehicle exceeds 56 km/h
(35 mph). Traction control will
remain off.
See Traction Control/Electronic
Stability Control 0276.
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See

Vehicle Load Limits0239. The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See Tire Pressure Monitor System
0 394.
Tire Fill Alert (If Equipped)
This feature provides visual and
audible alerts outside the vehicle to
help when inflating an underinflated
tire to the recommended cold tire
pressure. See “Tire Fill Alert (If
Equipped)” underTire Pressure
Monitor Operation 0395.Fuel (Gasoline - Except
L86 6.2L Engine)
Regular Fuel
Use only unleaded gasoline rated
87 octane or higher in your vehicle.
Do not use gasoline with an octane
rating lower as it may result in
vehicle damage and lower fuel
economy. See Fuel0292.
Fuel (Gasoline - L86 6.2L
Engine)
Premium Recommended Fuel
Use premium 93 octane unleaded
gasoline in your vehicle. Unleaded
gasoline with an octane rating as
low as 87 may be used, but it will
reduce performance and fuel
economy. See Fuel0292.
Fuel (Diesel)
For diesel vehicles, do not use
gasoline. See “Fuel for Diesel
Engines” in the Duramax diesel
supplement.

{Warning
If the key is unintentionally
rotated while the vehicle is
running, the ignition could be
moved out of the RUN position.
This could be caused by heavy
items hanging from the key ring,
or by large or long items attached
to the key ring that could be
contacted by the driver or
steering wheel. If the ignition
moves out of the RUN position,
the engine will shut off, braking
and steering power assist may be(Continued)

impacted, and airbags may not
deploy. To reduce the risk of
unintentional rotation of the
ignition key, do not change the
way the ignition key and Remote
Keyless Entry (RKE) transmitter,
if equipped, are connected to the
provided key rings.
The ignition key and key rings, and
RKE transmitter, if equipped, are
designed to work together as a
system to reduce the risk of
unintentionally moving the key out
of the RUN position. The ignition
key has a small hole to allow
attachment of the provided key ring.
It is important that any replacement
ignition keys have a small hole. See
your dealer if a replacement key is
required. The combination and size of the
rings that came with your keys were
specifically selected for your
vehicle. The rings are connected to
the key like two links of a chain to
reduce the risk of unintentionally
moving the key out of the RUN
position. Do not add any additional
items to the ring attached to the
ignition key. Attach additional items
only to the second ring, and limit
added items to a few essential keys
or small, light items no larger than
an RKE transmitter.

Tailgate
{Warning
It is extremely dangerous to ride
on the tailgate, even when the
vehicle is operated at low speeds.
People riding on the tailgate can
easily lose their balance and fall
in response to vehicle
maneuvers. Falling from a moving
vehicle may result in serious
injuries or death. Do not allow
people to ride on the tailgate. Be
sure everyone in your vehicle is in
a seat and using a seat belt
properly.
If equipped, to lock or unlock the
tailgate, use the RKE transmitter or
the key. See Remote Keyless Entry
(RKE) System Operation 037.
Open the tailgate by lifting up on its
handle while pulling the
tailgate down. To shut the tailgate, firmly push it
upward until it latches.
After closing the tailgate, pull it back
to be sure it latches securely.
Power Assist Steps
If equipped, the power assist steps,
when enabled, will extend when the
door is opened. They will retract
three seconds after the door is
closed or immediately if the vehicle
starts moving.
Keep hands, children, pets, objects,
and clothing clear of the power
assist steps when in motion.
The steps will reverse direction if
there is an obstruction. Remove the
obstruction, then open and close the
door on the same side to complete
the motion. If the obstruction is not
cleared, the assist steps remain
extended.
Slight movement of the steps while
extended is normal.
Kick Switch
1. Place the vehicle in P (Park)
and unlock the doors.
2. Kick the switch to extend the power assist step to the tire.
A DIC message displays.
3. Kick the switch again to return to normal operation.
