{Warning
Leaving children in a vehicle with a
Remote Keyless Entry (RKE) transmitter 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 RKE
transmitter in the vehicle, and children or
others could be caught in the path of a
closing window. Do not leave children in
a vehicle with an RKE transmitter.

Caution
Do not open the inner tailgate with the
primary tailgate open if there is a hitch
ball or trailer attached. This may damage
the tailgate.
To close the inner tailgate with the primary
tailgate closed, firmly push or pull it upward
until it latches. Pull it back to be sure it is
latched securely.
To close the inner tailgate with the primary
tailgate open:
.Hold the primary tailgate and firmly close
the inner tailgate.
.Raise the inner tailgate so it meets the
primary tailgate and close together at the
same time.
When using the tailgate step as a load stop,
the load must be secured as the load could
shift. See Cargo Tie-Downs 098.
MultiPro Inner Tailgate Enable/Disable
The MultiPro inner tailgate may be equipped
with an enable/disable feature to prevent
the inner tailgate from being opened when
a hitch or other equipment is installed that
could damage the inner tailgate.
To disable the inner tailgate from opening:
ensure that the remote key is within
1 meter (3 ft) of the rear bumper and then
hold the upper touchpad on the tailgate
handle for three seconds. The tail lamps will
flash to alert you that the inner gate has
been disabled. The inner and outer tailgate
can still be operated like a traditional
tailgate, but the inner gate will not be able
to be opened alone. To enable the inner tailgate function, hold
the upper touchpad on the handle for
3 seconds until the tail lamps flash. The
inner tailgate can now be opened separately
from the outer tailgate.
Tailgate Step
{Warning
To avoid personal injury, keep hands
away from the hinges when operating
the tailgate step.
With the primary and inner tailgates open,
the tailgate step can be lowered to access
the pickup bed.
Using the Step
Caution
When using the tailgate as a step, the
load rating is 170 kg (375 lb), which
includes a person and cargo. Overloading
the tailgate step can cause damage to
the tailgate system.

The system does not have to be manually
armed or disarmed.
The vehicle is automatically immobilized
when the vehicle is turned off.
The system is automatically disarmed when
the ignition is turned from off to on.
The security light, in the instrument cluster,
comes on if there is a problem with arming
or disarming the theft-deterrent system.
The system has one or more RKE
transmitters matched to an immobilizer
control unit in your vehicle. Only a correctly
matched RKE transmitter will start the
vehicle. If the transmitter is ever damaged,
you may not be able to start your vehicle.
When trying to start the vehicle, the
security light may come on briefly when the
ignition is turned on. If the engine does not
start and the security light stays on, there is
a problem with the system. Turn the
ignition off and try again.
If the vehicle will not change ignition modes
(ACC/ACCESSORY, on, off), and the RKE
transmitter appears to be undamaged, try
another transmitter. Or, you may try placing
the transmitter in the transmitter pocket
located in the center console. SeeRemote
Keyless Entry (RKE) System Operation 014. If the ignition mode will not change with
the other transmitter or with the
transmitter in the transmitter pocket, your
vehicle needs service. If the ignition does
change modes, the first transmitter may be
faulty. See your dealer who can service the
theft-deterrent system and have a new RKE
transmitter programmed to the vehicle.
It is possible for the immobilizer system to
learn new or replacement RKE transmitters.
Up to eight transmitters can be
programmed for the vehicle. To program
additional transmitters, see "Programming
Transmitters to the Vehicle" under
Remote
Keyless Entry (RKE) System Operation 014
Do not leave the transmitter or device that
disarms or deactivates the vehicle theft
system in the vehicle.
Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things, like
other vehicles, look farther away than
they really are. If you cut too sharply (Continued)
Warning (Continued)
into the right lane, you could hit a
vehicle on the right. Check the inside
mirror or glance over your shoulder
before changing lanes.
Standard Mirrors
The passenger side mirror is convex shaped.
A convex mirror surface is curved so more
can be seen from the driver seat.
Trailer-Tow Mirrors
The upper portion of both the driver and
passenger mirrors is flat.
The lower portion of both the driver and
passenger mirrors is convex. A convex mirror
surface is curved so more can be seen from
the driver seat. The lower portion is
adjusted manually.
Manual Mirrors
If equipped, adjust manual mirrors by
moving the mirror up and down or left to
right to see a little of the side of the vehicle
and to have a clear view behind the vehicle.
Using hood-mounted air deflectors and
add-on convex mirror attachments could
decrease mirror performance.

Trailer-Tow Mirrors
Extending Mirrors
Trailer tow mirrors can extend out for better
visibility when towing a trailer.
If equipped, grasp the mirror housing firmly
and pull back in one motion, arching slightly
toward the rear of the vehicle.
To return the mirror to its original position,
reverse the motion.
Auxiliary Cargo Mirror Lamps
If equipped, cargo mirror lamps face
rearward to provide more light on the sides
of the vehicle, if needed. SeeExterior Cargo
Lamps 0151.
Advanced Trailering Vision System Side
Cameras
If equipped, the Advanced Trailering Vision
System side cameras are on the bottom of
the outside mirrors. See “Surround Vision
(360 Degrees)” underAssistance Systems for
Parking or Backing 0283.

Caution (Continued)
lead to costly repairs not covered by the
vehicle warranty. This could also affect
the vehicle’s ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications0342.
If the light is flashing : A malfunction has
been detected that could damage the
emission control system and increase vehicle
emissions. Diagnosis and service may be
required.
To help prevent damage, reduce vehicle
speed and avoid hard accelerations and
uphill grades. If towing a trailer, reduce the
amount of cargo being hauled as soon as
possible.
If the light continues to flash, find a safe
place to park. Turn the vehicle off and wait
at least 10 seconds before restarting the
engine. If the light is still flashing, follow
the previous guidelines and see your dealer
for service as soon as possible.
If the light is on steady : A malfunction has
been detected. Diagnosis and service may be
required. Check the following:.If fuel has been added to the vehicle
using the capless funnel adapter,
make sure that it has been removed.
See
“Filling the Tank with a Portable
Gas Can” underFilling the Tank (Pickup
Model) 0306 orFilling the Tank (Chassis
Cab Model) 0307. The diagnostic system
can detect if the adapter has been left
installed in the vehicle, allowing fuel to
evaporate into the atmosphere. A few
driving trips with the adapter removed
may turn off the light.
.Poor fuel quality can cause inefficient
engine operation and poor driveability,
which may go away once the engine is
warmed up. If this occurs, change the fuel
brand. It may require at least one full
tank of the proper fuel to turn the light
off. See Recommended Fuel (6.2L
V8 Engine) 0305 or
Recommended Fuel (2.7L L4 and 5.3L
V8 Engines) 0304.
If the light remains on, see your dealer.
Emissions Inspection and Maintenance
Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument panel to
the left of the steering wheel. Connecting
devices that are not used to perform an
Emissions Inspection/Maintenance test or to
service the vehicle may affect vehicle
operation. See Add-On Electrical Equipment
0 338. See your dealer if assistance is
needed.
The vehicle may not pass inspection if:
.The light is on when the engine is
running.
.The light does not come on when the
ignition is on while the engine is off.
