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.

AUTOMATIC TEMPERATURE CONTROL
(ATC) — I
F EQUIPPED
Automatic Operation

1. Push the AUTO button on the faceplate, or the AUTO
button on the touchscreen on the Automatic
Temperature Control (ATC) Panel.

2. Next, adjust the temperature that you would like the system to maintain by adjusting the driver and
passenger temperature control buttons. Once the
desired temperature is displayed, the system will
achieve and automatically maintain that
temperature.
3. When the system is set up for your comfort level, it is not necessary to change the settings. You will
experience the greatest efficiency by simply allowing
the system to function automatically.
NOTE:
It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode, and blower speed to provide
comfort as quickly as possible.
 The temperature can be displayed in US or Metric units
by selecting the US/Metric customer-programmable
feature within Uconnect Settings
Úpage 191.
To provide you with maximum comfort in the Automatic
mode during cold start-ups, the blower fan will remain on
low until the engine warms up. The blower will increase in
speed and transition into Auto mode.
Manual Operation Override
This system offers a full complement of manual override
features. The AUTO symbol in the front ATC display will be
turned off when the system is being used in the manual
mode.
CLIMATE VOICE RECOGNITION —
I
F EQUIPPED
Adjust vehicle temperatures hands-free and keep
everyone comfortable while you keep moving ahead.
Push the VR button on the steering wheel. After the beep,
say one of the following commands:
 “Set driver temperature to 70 degrees”
 “Set passenger temperature to 70 degrees”
Did you know: Voice Command for Climate may only be
used to adjust the interior temperature of your vehicle.
Voice Command will not work to adjust the heated seats
or steering wheel if equipped.
OPERATING TIPS
Refer to the chart at the end of this section for suggested
control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling system is
functioning properly and the proper amount, type, and
concentration of coolant is used. Use of the Air
Recirculation mode during Winter months is not
recommended, because it may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control system
when the vehicle is being stored for an extended period of
time, see
Úpage 387.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select
Defrost or Mix mode and increase the front blower speed.
Do not use the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions, such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the air distribution box, they could plug the water
drains. In Winter months, make sure the air intake is clear
of ice, slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and pollen
from the air. Contact an authorized dealer to service your
cabin air filter, and to have it replaced when needed.

1. Tachometer

Indicates the engine speed in revolutions per
minute (RPM x 1000).
2. Voltmeter When the vehicle is in the RUN state, the gauge
indicates the electrical system voltage. The
pointer should stay within the normal range if the
battery is charged. If the pointer moves to either
extreme left or right and remains there during
normal driving, the electrical system should be
serviced.
NOTE:In vehicles equipped with Stop/Start, a reduced voltage
may be present during an Autostop.
3. Instrument Cluster Display
When the appropriate conditions exist, this display
shows the instrument cluster display messages
Úpage 98.
 The display always shows one of the main menu
items after ignition on. 4. Oil Pressure Gauge
The pointer should always indicate the oil pres -
sure when the engine is running. A continuous
high or low reading under normal driving condi -
tions may indicate a lubrication system malfunc -
tion. Immediate service should be obtained from
an authorized dealer.
NOTE:In vehicles equipped with Stop/Start, an oil pressure indi -
cation of zero is normal during an Autostop.
5. Speedometer
Indicates vehicle speed.
6. Temperature Gauge The pointer shows engine coolant temperature.
The pointer positioned within the normal range
indicates that the engine cooling system is oper -
ating satisfactorily.
 The pointer will likely indicate a higher tempera -
ture when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range. 7. Fuel Gauge
The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
 The fuel pump symbol points to the
side of the vehicle where the fuel door
is located.
WARNING!
A hot engine cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant.
You may want to call an authorized dealer for service if
your vehicle overheats
Úpage 350.
CAUTION!
Driving with a hot engine cooling system could damage
your vehicle. If the temperature gauge reads “H,” pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into
the normal range. If the pointer remains on the “H,”
turn the engine off immediately and call an authorized
dealer for service.

INSTRUMENT CLUSTER DISPLAY
Depending on your vehicles trim level, features and
options may vary.
Your vehicle will be equipped with an instrument cluster
display, which offers useful information to the driver. With
the ignition in the OFF mode, opening/closing of a door will
activate the display for viewing, and display the total miles,
or kilometers, in the odometer. Your instrument cluster
display is designed to display important information about
your vehicle’s systems and features. Using a driver interactive display located on the
instrument panel, your instrument cluster display can
show you how systems are working and give you warnings
when they are not. The steering wheel mounted controls
allow you to scroll through the main menus and
submenus. You can access the specific information you
want and make selections and adjustments.
