The power windows will be inhibited during the remote start and the
radio will not turn on.
The parking lamps will remain on and the engine will run for 5, 10, or
15 minutes, depending on how you programmed the system. To select
the duration of the remote start system refer to Message center in the
Instrument Cluster chapter.
Extending the engine run time
To keep the engine running for another remote start duration, repeat
Steps 1 and 2 with the engine still running. If you programmed the
duration to last 10 minutes, the second 10 minutes will begin
immediately so that, for example, if the vehicle had been running from
the first remote start for five minutes, the engine will continue to run for
a total of 15 minutes. You can only extend the remote start once.
If the vehicle is remote started then remote stopped, wait at least five
seconds before remote starting a second time.
The ignition switch must be turned to the on position and then back to
the off position or allow one hour to pass before using remote start
again.
Turning the engine off after using remote start
• Press
one time. The parking lamps will turn off.
You may have to be closer to the vehicle than when starting due to
ground reflection and the added noise of the running engine.
You can disable or enable the remote start system through the message
center. Refer to Message center in the Instrument Cluster chapter.
SECURICODE™ KEYLESS ENTRY SYSTEM (IF EQUIPPED)
You can use the keyless entry
keypad to lock or unlock the doors
without using a key.
The keypad can be operated with
the factory set 5–digit entry code;
this code is located on the owner’s wallet card in the glove box, is
marked on the computer module, and is available from your authorized
dealer. You can also create your own 5–digit personal entry code.
When pressing the controls on the keypad, press the middle of the
controls to ensure a good activation. Locks and Security

The Safety Canopy system, in combination with safety belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second row seats. The Safety Canopy will not interfere with children
restrained using a properly installed child or booster seat because it is
designed to inflate downward from the headliner above the doors along
the side window opening.
The Safety Canopy system is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the RCM to initiate Safety
Canopy inflation or when a certain likelihood of a rollover event is
detected by the rollover sensor.
The Safety Canopy is mounted to roof side-rail sheet metal, behind the
headliner, above each row of seats. The Safety Canopy is designed to
inflate between the side window area and occupants to further enhance
protection provided in side impact collisions and rollover events.
The fact that the Safety Canopy did not activate in a collision does not
mean that something is wrong with the system. Rather, it means the
forces were not of the type sufficient to cause activation. The Safety
Canopy is designed to inflate in certain side impact collisions or rollover
events, not in rear impact, frontal or near-frontal collisions, unless the
collision causes sufficient lateral deceleration or rollover likelihood.
WARNING: Several Safety
Canopy system components
get hot after inflation. Do not
touch them after inflation.
WARNING: If the Safety Canopy system has deployed, the
Safety Canopy will not function again unless replaced. The
Safety Canopy system (including the A, B, C, and D pillar trim and
headliner) must be inspected and serviced by an authorized dealer. If
the Safety Canopy is not replaced, it will not function again, which will
increase the risk of injury in a future collision.Seating and Safety Restraints

Tether strap attachment (rear SuperCab only)
There are three loops of webbing just above the back of the rear seat
(along the bottom edge of the rear window) in the SuperCab. These
loops are to be used as both routing loops and anchor loops for up to
three child safety seat tether straps.
These straps may be secured below the back of the seat with rubber
bands. To access, reach below the back of the seat and pull tether loop
out of the rubber band securing it.
Many tether straps cannot be tightened if the tether strap is hooked to
the loop directly behind the child seat. To provide a tight tether strap:
1. Route the tether strap through
the loop directly behind the child
seat.
2. Attach the strap hook onto the
loop behind an adjacent seating
position.Seating and Safety Restraints

If the engine fails to start using the preceding instructions (flexible
fuel vehicles only)
1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then
crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speeds up. If the engine still fails to start,
repeat Step 1.
Guarding against Exhaust Fumes
WARNING: If you smell exhaust fumes inside your vehicle, have
this checked immediately. Do not drive your vehicle if you smell
exhaust fumes. Carbon monoxide is present in exhaust fumes. Take
precautions to avoid its dangerous effects.
Important Ventilating Information
If you stop your vehicle and leave the engine idling for long periods of
time, we recommend that you do one of the following:
• Open the windows at least one inch (2.5 centimeters).
• Set your climate control to outside air.
ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt A/C electrical
source. The engine block heater plug can be located through the center
opening of the lower front bumper assembly. The block heater system is
most effective when outdoor temperatures reach below 0°F (-18°C).
For flexible fuel vehicles, if operating with E85 ethanol, an engine block
heater must be used if ambient temperature is below 0°F (-18°C).
See Cold weather starting earlier in this chapter for more information
on starting with ethanol.
WARNING: Failure to follow engine block heater instructions
could result in property damage or physical injury. Driving

Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle’s main electrical systems from overloads.
WARNING: Always disconnect the battery before servicing high
current fuses.
WARNING: To reduce risk of electrical shock, always replace
the cover to the power distribution box before reconnecting the
battery or refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Battery section of the Maintenance and Specifications chapter.
The high-current fuses are coded as follows:
