I NOTICE
Cruise Control (Option)
K2247
With Cruise Control, you can maintain a speed of about 25 mph (40 km/h)
or more without keeping your foot on the accelerator. This can\
really help
on long trips. Cruise Control does not work at speeds below a\
bout
25 mph
(40 krn/h).
When you apply your brakes, or the clutch pedal,
if you have a manual
transmission, the Cruise Control shuts
off.

at
I A a steady speed. So, don’t use your Cruise Control on winding
roads
or in heavy traffic.

roads, fast changes in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use Cruise Control
on slipPery roads.

To Resume a Set Speed
Suppose you set your Cruise Control at a desired speed and then 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 Control switch from
ON to WA for about half a second.
K2249
A If you hold the switch at WA longer than half a second, the vehicle
will keep going faster
until you release the switch or apply the brake.
You could be startled and even lose control. So unless you want to
go faster, don’t
hold the switch at WA .
I
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.
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.

K2207
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 three quarters of a second and then release it. Each time
you do this, your vehicle will go about 1 mph (1.6 km/h) faster.
To Reduce Speed While Using Cruise Control
i
b
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 half
a second. Each time you do this, you'll
go about 1 mph (1.6 kmlh)
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 hil\
ls, 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.
To Get Out of Cruise Control
There are several ways to turn off the Cruise Control:
.Y ..
1. Step lightly on the brake pedal or push the clutch pedal, if you have a
manual transmission; OR
2. Move the Cruise switch to OFF.
When you turn off the Cruise Control or the ignition, your Cruise Control set
speed memory is erased.

Windshield Wiper Blade lnserfs
J
PO232
To replace the windshield wiper blade insert, lift the wiper arm and rotate the
blade until
it is facing away from the windshield. Unlatch the end of the insert
from the holding clips. Remove the insert and slide a new one in place,
Make sure the blade
is secured in the clips.
Air Conditioning
Every now and then have your dealership check your air conditioning system
to be sure it has not lost any cooling ability,
If you think the system is not
working properly, have your dealership check
it out as soon as possible.
The air conditioning will not work when the temperature is below
40°F (4°C).
Fluid Leak Check
After the vehicle has been parked for a while, inspect the su\
rface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after
it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.
Lubrication
Accelerator Control System
Your maintenance schedule will tell you how often the accelerator linkage
pivot points must be lubricated. See “Recommended Fluids and Lubric\
ants”
in
the Index for the proper lubricant to use.
Accelerator cables and cruise control cables should not be lubr\
icated. Any
cables that are worn or are hard to pull
should be replaced.

Scheduled Maintenance Services
Periodic Maintenance Inspections
Listed below are inspections and services which should be performed at least
twice a year (for instance each spring or fall). You should let your GM
dealer’s service department or other qualified service center
do these jobs.
Make sure any necessary repairs are completed at once.
Steering and Suspension lnspectiont -Inspect front and rear suspension
and steering system
for damaged, loose or missing parts, signs of wear or
lack of lubrication. Inspect power steering lines and hoses for\
proper hook-up,
binding, leaks, cracks, chafing, etc. (On vehicles equipped wit\
h manual
steering gear, check for seal leakage.) Lubricate the steering linkage.
Accelerator Control System -Lubricate all pivot points with engine oil,
except the
TBI throttle shaft. Remove all external deposits from the injector
pump face cam on 6.2L and 6.5L engines.
Do this when the engine is cold
and not running.
Do not oil any accelerator or cruise control cables. Replace
any cables that have high effort
or excessive wear.
Exhaust System Inspection -Inspect the complete system including the
three-way catalytic converter. Inspect the body near the exhaust system. Look
for broken, damaged, missing
or out-of-position parts, as well as, open
seams, holes, loose connections
or other conditions which could cause a heat
buildup in the
floor pan or could let exhaust fumes seep into the passenger
compartments.
Drive Axle Service -Check readfront axle fluid level and add as needed.
Check constant velocity joints and axle seals for leaking.
Transfer Case (four-wheel drive) lnspectiont -Every 12 months or at oil
change intervals, check front axle and transfer case and add l\
ubricant when
necessary. Oil the control lever pivot point and all exposed control linkage. \
Check vent hose at transfer case for kinks and proper installa\
tion. More
frequent lubrication may be required on heavy-duty
or off-road use.
tA fluid loss in these systems may indicate a problem. Have them inspected
and repaired at once.
