220STARTING AND OPERATING
(Continued)
Perform the maintenance listed in the Scheduled
Servicing section for the proper maintenance
intervals
Úpage 393. When towing a trailer, never
exceed the GAWR or GCWR ratings.
Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when
towing while using a full size spare tire.
Proper tire inflation pressures are essential to
the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Ú page 444.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
Then, during the first 500 miles (805 km) that
a trailer is towed, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other parts
of the vehicle wear in at the heavier loads.
WARNING!
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured,
dynamic load shifts can occur that may be
difficult for the driver to control. You could lose
control of your vehicle and have a collision.
When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading
can cause a loss of control, poor performance
or damage to brakes, axle, engine, transmis -
sion, steering, suspension, chassis structure
or tires.
CAUTION!
Safety chains must always be used between
your vehicle and trailer. Always connect the
chains to the hook retainers of the vehicle
hitch. Cross the chains under the trailer
tongue and allow enough slack for turning
corners.
Vehicles with trailers should not be parked on
a grade. When parking, apply the parking
brake on the tow vehicle. Put the tow vehicle
transmission in PARK. For four-wheel drive
vehicles, make sure the transfer case is not in
NEUTRAL. Always, block or "chock" the trailer
wheels.
GCWR must not be exceeded.
Total weight must be distributed between the
tow vehicle and the trailer such that the
following four ratings are not exceeded :
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch
utilized.
WARNING!

AUX Switches
Wheel Alignment Mode
This setting must be activated before performing a wheel alignment, which
will move the vehicle to normal ride height and then disable the air
suspension system. Refer to an authorized dealer for further information.
Four Corner Air Suspension Modes There are three air suspension modes designed to protect the system in
unique situations. Tire Jack Mode is selected to assist in changing a spare
tire. Transport Mode is selected to assist when the vehicle is being flat bed
towed. Wheel Alignment Mode is selected before performing a wheel
alignment. Refer to an authorized dealer for further information.
Setting Name
Description
When the AUX Switches button is pressed on the touchscreen, the system displays the options related to the four vehicle AUX switches.
NOTE:Depending on the vehicle’s options, feature settings may vary.
Setting NameDescription
AUX 1-4 This setting will adjust the type and power source for the four vehicle AUX
switches. There are two types: “Latching” and “Momentary”. The power
source for the AUX switches can either be set to run off the “Battery” or from
the “Ignition”. In addition to setting the type and power source, you can set if
the vehicle will recall the previous state at which the AUX switches were set.
The Recalled Last State setting can be set to “On” or “Off”. Last state
conditions are met only if the type is set to Latching and the power source is
set to Ignition.
22_DT_OM_EN_USC_t.book Page 254
SAFETY331
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the Tire Pressure Monitoring System
Warning Light off.
Service TPMS Warning
If a system fault is detected, the Tire Pressure
Monitoring System (TPMS) Warning Light will flash
on and off for 75 seconds and then remain on
solid. The system fault will also sound a chime. In
addition, the instrument cluster will display a
"SERVICE TPM SYSTEM" message for a minimum
of five seconds and then display dashes (--) in
place of the pressure value to indicate which
sensor is not being received.
If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. If the
system fault no longer exists, the Tire Pressure
Monitoring System Warning Light will no longer
flash, and the "SERVICE TPM SYSTEM" message
will no longer display, and a pressure value will
display in place of the dashes. A system fault can
occur due to any of the following:
Signal interference due to electronic devices or
driving next to facilities emitting the same radio
frequencies as the Tire Pressure Monitoring
System sensors
Installing aftermarket window tinting that
contains materials that may block radio wave
signals
Accumulation of snow or ice around the wheels
or wheel housings
Using tire chains on the vehicle
Using wheels/tires not equipped with TPMS
sensors
A system fault may occur due to an incorrect TPMS
sensor location condition. When a system fault
occurs due to an incorrect TPMS sensor location,
the Tire Pressure Monitoring System (TPMS)
Warning Light will flash on and off for 75 seconds
and then remain on solid. The system fault will also
sound a chime. In addition, the instrument cluster
will display a Tire Pressure Temporarily Unavailable
message in place of the tire pressure display
screen. If the ignition switch is cycled, this
sequence will repeat, providing the system fault
still exists. If the system fault no longer exists, the
“Tire Pressure Monitoring System Warning Light”
will no longer flash and the tire pressure display
screen will be displayed showing the tire pressure
values the correct locations. Vehicles With Non-Matching Full Size Spare Or
Compact Spare
The non-matching full size spare or compact
spare tire does not have a TPMS sensor. There
-
fore, the TPMS will not monitor the pressure in
the non-matching full size spare or compact
spare tire.
If you install the non-matching full size spare or
compact spare tire in place of a road tire that
has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the Tire
Pressure Monitoring System (TPMS) Warning
Light and a “LOW TIRE” message will remain on
and a chime will sound. In addition, the graphic
in the instrument cluster will still display a pres -
sure value in a different color and an “Inflate to
XX” message.
After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the Tire Pressure
Monitoring System (TPMS) Warning Light will
flash on and off for 75 seconds and then remain
on solid. In addition, the instrument cluster will
display a "SERVICE TPM SYSTEM" message for a
minimum of five seconds and then display
dashes (--) in place of the pressure value.
