If your speed drops below 20 mph (32 km/h), or if the engine is not running
smoothly, you should downshift to the next lower gear. You may have to
downshift two or more gears
to keep the engine running smoothly or for good
performance.

Locking Rear Axle
If you have this feature, your rear axle can give you additional \
traction on
snow, mud, ice, sand or gravel.
It works like a standard axle most of the
time,
but when one of the rear wheels has no traction and the other does,
the locking feature
will allow the wheel with traction to move the vehicle.

To Resume a Set Speed
Suppose you set your Cruise Control at a desired speed and th\
en you apply
the brake. This, of course, shuts off the Cruise Control. But you don’t need
to reset it. Once you’re going about
25 mph (40 kmlh) or more, you can
move the Cruise switch

To Increase Speed While Using Cruise Control
There are two ways to go to a higher speed. Here’s the first:
1. Use the accelerator pedal to get to the higher speed.
K2207
2. Push the button at the end of the lever, then release the button and the
accelerator pedal.
You’ll now cruise at the higher speed.
Here’s the Second Way to go to a higher speed:
1. Move the Cruise switch from ON to WA. Hold it there until you get up
to the speed you want, and then release the switch.
2. To increase your speed in very small amounts, move the switch to WA
for less than half a second and then release it. Each time y\
ou do this,
your vehicle will go about
1 mph (1.6 km/h) faster.

To Reduce Speed While Using Cruise Control
1
K2260
1. Push in the button at the end of the lever until you reach the lower
speed you want, then release it.
2. To slow down in very small amounts, push the button for less than a
half second. Each time you do this, you’ll go 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When you take your foot
off the pedal, your vehicle will slow down to the Cruise Control speed you set
earlier.
Using Cruise Control on Hills
How well your Cruise Control will work on hills depends upon \
your speed,
load, and the steepness of the hills. When going up steep hills, you may
have to step on the accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear to keep your speed
down.
Of course, applying the brake takes you out of Cruise Control. Many
drivers find this to be too much trouble and don’t use Cruise Control on
steep hills.
When you turn
off the Cruise Control or the ignition, your Cruise Control set
speed memory
is erased.
