Four-Wheel Drive - Chevrolet 2003 Blazer Owner's Manual

Up-Shift Light
SHIFT
If you have a manual
transmission, you have a
SHIFT light on your
instrument panel cluster.
This light will show you when to shift to the next higher
gear for best fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road and traffic conditions let you.
For the best fuel economy, accelerate slowly and shift
when the light comes on.
While you accelerate, it is normal for the light to go on
and off if you quickly change the position of the
accelerator. Ignore the SHIFT light when you downshift.
3
If you skip a gear when you downshift, you
could lose control of your vehicle. You could
injure yourself or others. Don't shift down
more than one gear at a time when you
downshift.
If your vehicle has four-wheel drive and is equipped with
a manual transmission, disregard the up-shift light
when the transfer case is in 4LO.
Four-wheel Drive
If your vehicle has four-wheel-drive, you can send your
engine's driving power to all four wheels for extra
traction. To get the most satisfaction out of
four-wheel-drive, you must be familiar with its operation.
Read the part that follows before using four-wheel-drive.
You should use two-wheel high (2HI) for most normal
driving conditions.
Notice: Driving in the 4-WHEEL HIGH (4HI) or
4-WHEEL LOW (4LO) positions for a long time on
dry or wet pavement could shorten the life of
your vehicle's drivetrain.
