Shifting Out of Four-Wheel Low
To shift from Four-Wheel Low to Four-Wheel High,
AUTO 4WD or Two-Wheel High, your vehicle must be
stopped or moving less than 3 mph (5 km/h) with the
transmission in NEUTRAL (N) and the ignition in RUN.
The preferred method for shifting out of Four-Wheel
Low is to have your vehicle moving 1 to 2 mph
(1.6 to 3.2 km/h). Press and release the Four-Wheel
High, AUTO 4WD or Two-Wheel High button. You must
wait for the Four-Wheel High, AUTO 4WD or Two-Wheel
High indicator light to stop ashing and remain on
before shifting your transmission into gear.
Notice:Shifting the transmission into gear before
the Four-Wheel Low indicator light has stopped
ashing could damage the transfer case. To help
avoid damaging your vehicle, always wait for the
Four-Wheel Low indicator light to stop ashing
before shifting the transmission into gear.It is typical for your vehicle to exhibit signi cant
engagement noise and bump when shifting between
Four-Wheel Low and Four-Wheel High ranges or from
NEUTRAL with the engine running.
If the Four-Wheel High, AUTO 4WD or Two-Wheel High
switch is pressed when your vehicle is in gear and/or
moving, the Four-Wheel High, AUTO 4WD or Two-Wheel
High indicator light will ash for 30 seconds but will not
complete the shift unless your vehicle is moving less than
3 mph (5 km/h) and the transmission is in NEUTRAL (N).

6. Simultaneously press and hold the Two-Wheel High
and Four-Wheel Low buttons for 10 seconds.
The NEUTRAL light will come on when the transfer
case shift to NEUTRAL is complete.

is in NEUTRAL (N) by shifting the transmission
to REVERSE (R) for one second, then shift
the transmission to DRIVE (D) for one second.

After the transfer case has shifted out of
NEUTRAL the NEUTRAL light will go out.
4. Release the parking brake.
Notice:Shifting the transmission into gear
before the Four-Wheel Low indicator light has
stopped ashing could damage the transfer case.
To help avoid damaging your vehicle, always
wait for the Four-Wheel Low indicator light to stop
ashing before shifting the transmission into gear.
5. Start the engine and shift the transmission to
the desired position.
Excessively shifting the transfer case into or out of
the different modes may cause the transfer case to enter
the shift protection mode. This will protect the transfer
case from possible damage and will only allow the
transfer case to respond to one shift per 10 seconds.
The transfer case may stay in this mode for up to
three minutes.

Mirror Operation
When turned on, this mirror automatically dims to the
proper level to minimize glare from any headlamps
behind you after dark.
O(On/Off):This is the on/off button for the automatic
dimming feature and compass. Press the far left button,
located below the mirror face, for up to three seconds to
turn the feature on and off. A light on the mirror will
be lit while the feature is turned on.
Compass Operation
Press the on/off button once to turn the compass
on or off.
There is a compass display in the window in the
upper right corner of the mirror face. The compass
displays a maximum of two characters. For example,
“NE” is displayed for north-east.
Compass Calibration
Press and hold the on/off button down for nine seconds
to activate the compass calibration mode. CAL will
be displayed in the compass window on the mirror.
The compass can be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the display
reads a direction.
Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. The mirror is
set to zone eight upon leaving the factory. It will be
necessary to adjust the compass to compensate for
compass variance if you live outside zone eight. Under
certain circumstances, such as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. If not adjusted to account for compass
variance, your compass could give false readings.
