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.

EXTERIOR LIGHTS
HEADLIGHT SWITCH
The headlight switch is located on the left side of the
instrument panel. This switch controls the operation of the
headlights, parking lights, automatic headlights (if
equipped), instrument panel light dimming, cargo light/
trailer spotter lights (if equipped), and fog lights (if
equipped).

Headlight Switch Headlight Switch (Vehicles Sold In Canada)

NOTE:
Vehicles sold in Canada are equipped with a headlight
switch with an AUTO and ON detent but without an OFF
detent. Headlights will be deactivated when the headlight
switch is placed in the parking lights position. However,
the Daytime Running Lights (DRLs) will be activated along
with the front and rear marker lights. The DRLs may be
deactivated when the parking brake is engaged.
To turn on the headlights, rotate the headlight switch
clockwise. When the headlight switch is on, the parking
lights, taillights, license plate light and instrument panel
lights are also turned on. To turn off the headlights, rotate
the headlight switch back to the O (off) position.
WARNING!
 Vehicle exhaust contains carbon monoxide, a
dangerous gas. Do not run your vehicle in the garage
while programming the transceiver. Exhaust gas can
cause serious injury or death.
 Your motorized door or gate will open and close while
you are programming the universal transceiver.
Do not program the transceiver if people, pets or
other objects are in the path of the door or gate. Only
use this transceiver with a garage door opener that
has a “stop and reverse” feature as required by
Federal safety standards. This includes most garage
door opener models manufactured after 1982.
Do not use a garage door opener without these
safety features.

NOTE:For vehicles sold in Canada, rotate the headlight switch
clockwise from the parking lights and instrument panel
lights position to the first detent to turn on headlights,
parking lights, and instrument panel lights. Rotate the
headlight switch to the second detent for the AUTO
position.
NOTE:
Your vehicle is equipped with plastic headlight and fog
light (if equipped) lenses that are lighter and less
susceptible to stone breakage than glass lights. Plastic
is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
 To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth.
To remove road dirt, wash with a mild soap solution
followed by rinsing.
MULTIFUNCTION LEVER
The multifunction lever is located on the left side of the
steering column.

Multifunction Lever

DAYTIME RUNNING LIGHTS (DRLS)
The Daytime Running Lights (DRLs) come on whenever the
engine is running, and the low beams are not on. The
lights will remain on until the ignition is placed in the OFF
or ACC position, or the parking brake is engaged.
NOTE:
For vehicles sold in Canada, the Daytime Running
Lights will automatically deactivate when the front fog
lights are turned on.
 If allowed by law in the country in which the vehicle was
purchased, the Daytime Running Lights can be turned
on and off using the Uconnect system
Úpage 191.
 On some vehicles, the Daytime Running Lights may
deactivate, or reduce intensity, on one side of the
vehicle (when a turn signal is activated on that side), or
on both sides of the vehicle (when the hazard warning
lights are activated).
HIGH/LOW BEAM SWITCH
Push the multifunction lever toward the instrument panel
to switch the headlights to high beams. Pulling the
multifunction lever back will turn the low beams on.
AUTOMATIC HIGH BEAM HEADLAMP
C
ONTROL — IF EQUIPPED
The Automatic High Beam Headlamp Control system
provides increased forward lighting at night by automating
high beam control through the use of a camera mounted
on the inside rearview mirror or a windshield mounted
camera. These cameras detect vehicle specific light and
automatically switch from high beams to low beams until
the approaching vehicle is out of view.
NOTE:
 The Automatic High Beam Headlamp Control can be
turned on or off by selecting “ON” under “Auto Dim
High Beams” within your Uconnect Settings
Úpage 191, as well as turning the headlight switch to
the AUTO position.
 Broken, muddy, or obstructed headlights and taillights
of vehicles in the field of view will cause headlights to
remain on longer (closer to the vehicle). Also, dirt, film,
and other obstructions on the windshield or camera
lens will cause the system to function improperly.
 If the windshield or Automatic High Beam Headlamp
Control mirror is replaced, the mirror must be re-aimed
to ensure proper performance. See a local authorized
dealer.
 To opt out of the Advanced Auto High Beam Sensitivity
Control (default) and enter Reduced High Beam Sensi -
tivity Control (not recommended), toggle the high beam
lever six full on/off cycles within 10 seconds of placing
the ignition in the ON position. The system will return to
the default setting upon placing the ignition in the OFF
position.
CAUTION!
Do not use abrasive cleaning components, solvents,
steel wool or other abrasive materials to clean the
lenses.
