Compass Settings — If Equipped
After pressing the “Compass Settings” button on the
touchscreen the following settings will be available:
• Variance
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 automatically compensate for the
differences, and provide the most accurate compass
heading.
NOTE: Keep magnetic materials away from the top of the
instrument panel, such as iPod’s, Mobile Phones, Lap-
tops 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
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 Compass Variance Map326 UNDERSTANDING YOUR INSTRUMENT PANEL

conditions may be reduced. In all cases, normal operation
will resume once the transmission temperature has risen
to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in fourth gear (for 66RFE transmission) or third gear (for
AS66RC transmission) regardless of which forward gear
is selected. If an AS66RC equipped truck enters Limp
Home Mode at highway speeds, it will initially engage
fifth gear, until the vehicle slows to a speed where third
gear can be engaged. PARK, REVERSE, and NEUTRAL
will continue to operate. The Malfunction Indicator Light
(MIL) may be illuminated. Limp Home Mode allows the
vehicle to be driven to an authorized dealer for service
without damaging the transmission. In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur. 5STARTING AND OPERATING 415

If the transmission cannot be reset, authorized dealer
service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the
transmission is in DRIVE. For example, if you set the
transmission gear limit to 4 (fourth gear), the transmis-
sion will not shift above fourth gear, but will shift
through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the gear selector is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Tapping the ERS (-)
switch will activate ERS mode, display the current gear in
the instrument cluster, and set that gear as the top
available gear. Once in ERS mode, tapping (-) or (+) will
change the top available gear. To exit ERS mode, simply push and hold the ERS (+)
switch until the gear limit display disappears from the
instrument cluster. Column Gear Selector416 STARTING AND OPERATING

FOUR-WHEEL DRIVE OPERATION — IF
EQUIPPED
Four-wheel drive trucks are equipped with either a
manually shifted transfer case or an electronically shifted
transfer case. Refer to the operating instructions for your
transfer case, located in this section for further informa-
tion.
Manually Shifted Transfer Case — If Equipped
The transfer case provides four mode positions:
• Two-wheel drive high range (2H) • Four-wheel drive high range (4H)
• Neutral (N)
• Four-wheel drive low range (4L)
This transfer case is intended to be driven in the 2H
position for normal street and highway conditions such
as dry, hard surfaced roads.
When additional traction is required, the 4H and 4L
positions can be used to lock the front and rear drive-
shafts together and force the front and rear wheels to
rotate at the same speed. This is accomplished by simply
moving the gear selector to the desired positions once the
appropriate speed and gear requirements are met, refer
to “Shifting Procedure – Manually Shifted Transfer Case”
in this section for further information. 5STARTING AND OPERATING 423
