CAUTION!
• When installing the power distribution center cover, it is important to ensure the cover is properly positioned
and fully latched. Failure to do so may allow water to
get into the power distribution center and possibly
result in an electrical system failure.
• When replacing a blown fuse, it is important to useonly a fuse having the correct amperage rating. The use
of a fuse with a rating other than indicated may result
in a dangerous electrical system overload. If a properly
rated fuse continues to blow, it indicates a problem in
the circuit that must be corrected. CAUTION!

544 SERVICING AND MAINTENANCE
Consult an authorized tire dealer for tire repairs and addi-
tional information.
Damaged Run Flat tires, or Run Flat tires that have experi -
enced a loss of pressure should be replaced immediately
with another Run Flat tire of identical size and service
description (Load Index and Speed Symbol). Replace the tire
pressure sensor as well as it is not designed to be reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the Run
Flat mode. A Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a Run Flat tire
reaches the run flat mode it has limited driving capabilities
and needs to be replaced immediately. A Run Flat tire is not
repairable. When a run flat tire is changed after driving with
underinflated tire condition, please replace the TPM sensor
as it is not designed to be reused when driven under run flat
mode (14 psi (96 kPa)) condition. NOTE:
TPM Sensor must be replaced after driving the vehicle on a
flat tire condition.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the run flat mode.

See the tire pressure monitoring section for more information.

Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle's wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of Emer
-
gency” for further information.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause tire damage or
failure. A tire could explode and injure someone. Do not
spin your vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when you are
stuck, and do not let anyone near a spinning wheel, no
matter what the speed.

(Continued)
NOTE:
If your vehicle is equipped with a Tire Pressure Information
System (TPIS):
• The Tire Pressure Information System (TPIS) uses uniquesensors in the inner rear wheels to help identify them from
the outer rear wheels, because of this, the inner and outer
wheel locations can’t be switched.
• After a tire rotation is completed, as shown below, the system can auto learn the locations of each sensor ID. Auto
learning/localization occurs when the vehicle ignition
status is changed from Off to On and speeds of greater
than 5 mph (8km/h) are obtained and remain over 5 mph
(8km/h) for at about a 15 minute period. You may need to
drive for 20 minutes to account slower speeds and stops.
• If the tires are rotated incorrectly, The auto localization of the TPIS sensors will fail to locate correctly resulting in
incorrect locations for the pressure values displayed in the
instrument cluster.
DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories were established by
the National Highway Traffic Safety Administration. The
specific grade rating assigned by the tire's manufacturer
in each category is shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform to Federal safety
requirements in addition to these grades.
CAUTION!
• 3500 Dual Rear Tires may only have one approved direction of rotation. This is to accommodate the asym -
metrical design (tread pattern) of the On/Off-Road tire
and the use of Outline White Letter (OWL) tires.
• When replacing a flat, the spare tire may have to be remounted on the rim, or installed at a different loca -
tion, to maintain the correct placement of the tire on the
wheel relative to the tire/wheel position on the truck.
For example, if the spare is used to replace an outer rear
tire it will have to be remounted on the rim so that the
wheel is dished inward. That way the tread design of
asymmetrical tires and the white writing of the OWL
tires will maintain proper position. CAUTION!

Compass Settings — If Equipped
After pressing the “Compass Settings” button on the touchscreen, the following settings will be available:Setting Name Selectable Options
Variance 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
NOTE:
• Compass Variance is the difference between Magnetic North and Geographic North. To compensate for the differences the variance should be set for the zone where the vehicle is driven, per the zone map. Once properly set, the compass will auto -
matically compensate for the differences, and provide the most accurate compass heading.
• Keep magnetic materials away from the top of the instrument panel, such as iPod's, Mobile Phones, Laptops and Radar Detectors. This is where the compass module is located, and it can cause interference with the compass sensor, and it may
give false readings.
Perform Compass Calibration On
Off
NOTE:
Press the “Calibration” button on the touchscreen to change this setting. This compass is self-calibrating, which eliminates
the need to manually reset the compass. When the vehicle is new, the compass may appear erratic until it is calibrated. You
may also calibrate the compass by pressing the “ON” button on the touchscreen and completing one or more 360-degree
turns (in an area free from large metal or metallic objects). The compass will now function normally.
