Electronic Transfer Case - Chevrolet 1994 S-10 Pickup Owner's Manual

Electronic Transfer Case
If your four-wheel drive vehicle has the electronic transfer case, the transfer
case switches are on the right side of your instrument panel above the radio
controls. Use these switches to shift into and out of four-wheel drive. You
can choose among three driving settings:
1. 2HI: This setting is for driving in most street and highway situations.
Your front axle is not engaged in two-wheel drive.
2. 4HI: This setting engages your front axle to help drive your vehicle.
Use 4HI when you need extra traction, such as on snowy or icy roads,
or in most off-road situations.
3. 4LO: This setting also engages your front axle to give you extra
traction. You may never need 4LO. It sends the maximum power to all
four wheels. You might choose 4LO if you were driving off-road in
sand, mud, deep snow and climbing or descending steep hills.
Amber indicator lights in the switches show you which setting you are in.
The indicator lights will come on briefly when you turn on the ignition and
one will stay on. If the lights do not come on, you should take your vehicle
in for service. When shifting, an indicator light will flash until the shift is
completed then remain solidly lit.
To shift from 2HI to 4HI: Press and release the 4HI switch. This can be
done at any speed, and the front axle will lock automatically.
To shift from 4HI to 2HI: Press and release the 2HI switch. This can be
