SeeForward Collision Alert (FCA)
System 0308.
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) 0310.
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) 0312.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. It may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane
marking without using a turn signal
in that direction. It may also provide
a Lane Departure Warning (LDW)
alert as the lane marking is crossed.
The system will not assist or alert if
it detects that you are actively
steering. Override LKA by turning
the steering wheel. LKA uses a
camera to detect lane markings
between 60 km/h (37 mph) and
180 km/h (112 mph).
See Lane Departure Warning (LDW)
(2500/3500 Series) 0312 andLane
Keep Assist (LKA) (1500 Series)
0 313.
Rear Vision
Camera (RVC)
If equipped, RVC shows a view of
the area behind the vehicle on the
infotainment display when the
vehicle is shifted into R (Reverse) to
aid with parking and low-speed
backing maneuvers.
See Assistance Systems for Parking
or Backing 0306.
Parking Assist
If equipped, Rear Parking
Assist (RPA) uses sensors on the
rear bumper to assist with parking
and avoiding objects while in
R (Reverse). It operates at speeds
less than 8 km/h (5 mph). RPA may
show a warning triangle on the
infotainment display and a graphic
on the instrument cluster to provide
the object distance. In addition,
multiple beeps or seat pulses may
occur if very close to an object.
The vehicle may also have the Front
Parking Assist system.
See Assistance Systems for Parking
or Backing 0306.

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 0299.
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 Limits
0265. 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
0 410.
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 Fuel0315.
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 Fuel0315.

Leaving children in a vehicle with
the ignition key is dangerous and
children or others could be
seriously injured or killed. They
could operate the power windows
or other controls or make the
vehicle move. The windows will
function with the keys in the
ignition, and children or others
could be caught in the path of a
closing window. Do not leave
children in a vehicle with the
ignition key.

{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)
Warning (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.
