When the truck is used to carry a slide-in camper, the total cargo load of the truck consists
of the manufacturer’s camper weight figure, the weight of installed additional camper
equipment not included in the manufacturer’s camper weight figure, the weight of camper
cargo, and the weight of passengers in the camper. The total cargo load should not exceed
the truck’s cargo weight rating and the camper’s CG should fall within the truck’s
recommended CG zone when installed.
Secure loose items to prevent weight shifts that could affect the balance of your vehicle.
When the truck camper is loaded, drive to a scale and weigh the front and rear wheels
separately, to determine axle loads. Individual axle loads should not exceed either of the
Gross Axle Weight Ratings (GAWR). The total of the axle loads should not exceed the Gross
Vehicle Weight Rating (GVWR). If weight ratings are exceeded, move or remove items to
get the total weight below the ratings.
NOTE:These ratings are also provided on the Vehicle Certification Label located on the driver’s
side B-pillar. See Úpage 172 for more information.
For any additional instructions, please contact your conversion/camper manufacturer or
an authorized dealer.

Programming And Requesting Additional
Key Fobs
Programming the key fob may be performed by an
authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it cannot be
repurposed and reprogrammed to another vehicle.
 Only key fobs that are programmed to the vehicle elec -
tronics can be used to start and operate the vehicle. Duplication of key fobs may be performed at an authorized
dealer. This procedure consists of programming a blank
key fob to the vehicle electronics. A blank key fob is one
that has never been programmed.
NOTE:

When having the Sentry Key Immobilizer system
serviced, bring all vehicle keys with you to an autho -
rized dealer.
 Keys must be ordered to the correct key cut to match
the vehicle locks.
SENTRY KEY
The Sentry Key Immobilizer system prevents unauthorized
vehicle operation by disabling the engine. The system
does not need to be armed or activated. Operation is
automatic, regardless of whether the vehicle is locked or
unlocked.
The system uses a key fob, keyless push button ignition
and a Radio Frequency (RF) receiver to prevent
unauthorized vehicle operation. Therefore, only key fobs
that are programmed to the vehicle can be used to start
and operate the vehicle. The system cannot reprogram a
key fob obtained from another vehicle. After placing the ignition in the ON/RUN position, the
Vehicle Security Light will turn on for three seconds for a
bulb check. If the light remains on after the bulb check, it
indicates that there is a problem with the electronics.
In addition, if the light begins to flash after the bulb check,
it indicates that someone attempted to start the engine
with an invalid key fob. In the event that a valid key fob is
used to start the engine but there is an issue with the
vehicle electronics, the engine will start and shut off after
two seconds.
If the Vehicle Security Light turns on during normal vehicle
operation (vehicle running for longer than 10 seconds), it
indicates that there is a fault in the electronics. Should
this occur, have the vehicle serviced as soon as possible
by an authorized dealer.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics
Úpage 402.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
WARNING!

The integrated key fob contains a coin cell battery.
Do not ingest the battery; there is a chemical burn
hazard. If the coin cell battery is swallowed, it can
cause severe internal burns in just two hours and
can lead to death.
 If you think a battery may have been swallowed or
placed inside any part of the body, seek immediate
medical attention.
 Keep new and used batteries away from children.
If the battery compartment does not close securely,
stop using the product and keep it away from
children.
WARNING!
Always remove the key fobs from the vehicle and lock
all doors when leaving the vehicle unattended.
 For vehicles equipped with Keyless Enter ‘n Go™
Ignition, always remember to place the ignition in the
OFF position when exiting the vehicle.
CAUTION!
The Sentry Key Immobilizer system is not compatible
with some aftermarket Remote Start systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.

23_DT_OM_EN_USC_t.book Page 19

GETTING TO KNOW YOUR VEHICLE21
NOTE:
The key fob may not be detected by the vehicle Keyless
Enter ‘n Go™ system if it is located next to a mobile
phone, laptop or other electronic device; these devices
may block the key fob’s wireless signal and prevent the
Keyless Enter ‘n Go™ system from starting the vehicle.
 For more information on normal engine starting, see
Úpage 118.
 When opening the driver's door and the ignition is in
the ON/RUN position (engine not running), a chime will
sound to remind you to place the ignition in the OFF
position. In addition to the chime, the message “Igni-
tion or Accessory ON” will display in the cluster.
REMOTE START — IF EQUIPPED
This system uses the key fob to start the engine
conveniently from outside the vehicle while still
maintaining security. The system has a range
of approximately 328 ft (100 m).
Remote Start is used to defrost windows in cold weather
and to reach a comfortable climate in all ambient
conditions before the customer enters the vehicle.
NOTE:Obstructions between the vehicle and key fob may reduce
this range Úpage 402.
HOW TO USE REMOTE START
Push and release the Remote Start button on the key fob
twice within five seconds. The vehicle doors will lock, the
parking lights will flash, and the horn will chirp twice
(if programmed). Then, the engine will start, and the
vehicle will remain in the Remote Start mode for a
15 minute cycle.
Pushing the Remote Start button a third time shuts the
engine off. To drive the vehicle, push the unlock button, and place the
ignition in the ON/RUN position.
NOTE:

With Remote Start, the engine will only run for
15 minutes.
 Remote Start can only be used twice.
 If an engine fault is present or fuel level is low, the
vehicle will start and then shut down in 10 seconds.
 The parking lights will turn on and remain on during
Remote Start mode.
 For security, power window and power sunroof opera -
tion (if equipped) are disabled when the vehicle is in
the Remote Start mode.
 The ignition must be placed in the ON/RUN position
before the Remote Start sequence can be repeated for
a third cycle.
All of the following conditions must be met before the
engine will remote start:
 Gear selector in PARK
 Doors closed
 Hood closed
 Hazard switch off
 Brake switch inactive (brake pedal not pressed)
 Battery at an acceptable charge level
CAUTION!
An unlocked vehicle is an invitation for thieves. Always
remove key fob from the vehicle and lock all doors
when leaving the vehicle unattended.
WARNING!
Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains carbon
monoxide (CO) which is odorless and colorless.
Carbon monoxide is poisonous and can cause
serious injury or death when inhaled.
 Keep key fobs away from children. Operation of the
Remote Start system, windows, door locks or other
controls could cause serious injury or death.2

previous settings.
Manual Temperature Control (MTC) — If Equipped

In ambient temperatures of 40°F (4.5°C) or below, the
climate settings will default to maximum heat, with
fresh air entering the cabin. If the front defrost timer
expires, the vehicle will enter Mix Mode.
 In ambient temperatures from 40°F (4.5°C) to 78°F
(26°C), the climate settings will be based on the last
settings selected by the driver.
 In ambient temperatures of 78°F (26°C) or above, the
climate settings will default to MAX A/C, Bi-Level mode,
with Recirculation on.
For more information on ATC, MTC, and climate control
settings, see
Úpage 54.
NOTE:These features will stay on through the duration of Remote
Start, or until the ignition is placed in the ON/RUN
position. The climate control settings will change, and exit
the automatic defaults, if manually adjusted by the driver
while the vehicle is in Remote Start mode. This includes
turning the climate controls off using the OFF button.
WARNING!
 Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains carbon
monoxide (CO) which is odorless and colorless.
Carbon monoxide is poisonous and can cause
serious injury or death when inhaled.
 Keep key fobs away from children. Operation of the
Remote Start system, windows, door locks or other
controls could cause serious injury or death.
