Chevrolet 2008 Silverado 1500 Pickup Owner's Manual page 133

You can shift from Two-Wheel-Drive High to
Four-Wheel-Drive High or Four-Wheel-Drive High to
Two-Wheel-Drive High while the vehicle is moving. In
extremely cold weather, it may be necessary to stop or
slow the vehicle to shift into Four-Wheel-Drive High.
When Using the Manual Transfer Case
•
Shifting should be made using quick motions.
Shifting slowly may make it more difficult to shift.
•
You may notice that it is harder to shift when the
vehicle is cold. After the vehicle warms up the
shifting will return to normal.
•
While in Four-Wheel High or Four-Wheel-Drive Low
you may experience reduced fuel economy.
•
Avoid driving in Four-Wheel Drive on clean, dry
pavement. It may cause your tires to wear faster,
and make the transfer case harder to shift and run
noisier.
•
If the transfer case shifter is in the NEUTRAL
position and you have difficulty reaching the
selected transfer case mode, with the engine
running, shift the transmission momentarily to
drive and then back to NEUTRAL. This will realign
the gear teeth in the transfer case and allow
you to complete the shift.
Shifting from Two-Wheel-Drive High to
Four-Wheel-Drive High
•
Shifts between Two-Wheel-Drive High and
Four-Wheel-Drive High can be made at any
vehicle speed.
•
Shift the transfer case lever in one continuous
motion into either the Four-Wheel-Drive High
or Two-Wheel-Drive High position.
•
In extremely cold weather, it may be necessary to
slow or stop the vehicle to shift into Four-wheel-Drive
High until your vehicle has warmed up.
•
While in Four-Wheel-Drive High, your vehicle can be
driven at any posted legal speed limit.
