Windshield Wipers
The windshield wiper lever is located on the right side of
the steering column.
Move the lever to the following positions:
1 (High Speed) : Fast wipes.
6 (Low Speed) : Slow wipes.
& (Delay) : Use to set a delay between wipes.
x (Delay Adjustment) : Use for a delayed wiping
cycle. Turn the intermittent adjust band down for a
longer delay or up for a shorter delay. The wiper speed
can only be manually adjusted when the lever is in this
position. 9
(Off) : Turns off the windshield wipers.
8 (Mist) : Move all the way down to mist and release
for a single wiping cycle. The windshield wipers will stop
after one wipe. Hold the band on mist longer for more
wipes.
Heavy snow or ice can overload the wipers. If this
occurs, a circuit breaker will stop the wipers until the
motor cools. Clear all ice and snow from the wiper
blades before using them. If frozen to the windshield,
carefully loosen them or thaw them. Damaged wiper
blades should be replaced. See Windshield Wiper
Blade Replacement on page 6‑59.
Windshield Washer
The lever on the right side of the steering column
also controls the windshield washer. There is a button
at the end of the lever. To spray washer fluid on the
windshield, press the button and hold it. The washer
will spray until you release the button. The wipers will
continue to clear the window for about six seconds after
the button is released and then stop or return to your
preset speed.

Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle's tires so they actually ride on the water.
This can happen if the road is wet enough and you are
going fast enough. When your vehicle is hydroplaning, it
has little or no contact with the road.
There is no hard and fast rule about hydroplaning.
The best advice is to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather driving tips
include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in good shape.
.Keep the windshield washer fluid reservoir filled.
.Have good tires with proper tread depth. See Tireson page 6‑62.
.Turn off cruise control.
Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
.Windshield Washer Fluid: Reservoir full? Windows
clean —inside and outside?
.Wiper Blades: In good shape?
.Fuel, Engine Oil, Other Fluids: All levels checked?
.Lamps:Do they all work and are lenses clean?
.Tires:Are treads good? Are tires inflated to
recommended pressure?
.Weather and Maps: Safe to travel? Have
up-to-date maps?

Windshield Replacement
The windshield is part of the Head-Up Display (HUD)
system. If you ever have to get the windshield replaced,
get one that is designed for HUD or the HUD image
may look out of focus.
Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for wear
and cracking. See Scheduled Maintenanceon
page 7‑3for more information.
Replacement blades come in different types and are
removed in different ways. For the proper type and
length, see Maintenance Replacement Parts
on
page 7‑12. It is a good idea to clean or replace the wiper blade
assembly every six months. Allowing the wiper blade
arm to touch the windshield when no wiper blade is
installed could damage the windshield. Any damage
that occurs would not be covered by the vehicle's
warranty. Do not allow the wiper blade arm to touch
the windshield.
To remove the wiper blade assembly:
1. Open the hood to gain access to the windshield wipers.
2. Lift the wiper arm away from the windshield.
6-59
Windshield and Wiper Blades
Clean the outside of the windshield with glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer fluid or a mild
detergent. Wash the windshield thoroughly when
cleaning the blades. Bugs, road grime, sap, and a
buildup of vehicle wash/wax treatments may cause
wiper streaking. Replace the wiper blades if they are
worn or damaged.
Wipers can be damaged by:
.Extreme dusty conditions
.Sand and salt
.Heat and sun
.Snow and ice, without proper removal
Removable Roof Panel
Notice: If you use a glass treatment and/or
conditioner that contains ethyl alcohol or ethyl
sulfate on the roof panel, you could damage the
panel. The repairs would not be covered by your
warranty. Only use a GM-approved glass cleaner
on the roof panel.
Special care is necessary when cleaning, removing,
and/or storing the roof panel.
.Flush with water to remove dust and dirt, then dry
the panel.
.Clean a transparent roof panel with GM Glass
Cleaner. Leave the cleaner on the panel for
one minute, then wipe the panel with a soft,
lint-free cloth. Do not use glass cleaner on a
painted roof panel.
.Do not use abrasive cleaning materials on either
type of panel.
If water drops are frequently allowed to dry on the roof
panel, impurities in the water will adhere to the top.
These impurities may etch or mar the finish. When the
panel gets wet, dry it off.
6-96
.Tire wear inspection. SeeTire Inspection and
Rotation on page 6‑76.
.Fluids visual leak check (or every 12 months,
whichever occurs first). A leak in any system must
be repaired and the fluid level checked.
.Engine air cleaner filter inspection (vehicles
driven in dusty conditions only). See Engine Air
Cleaner/Filter on page 6‑27.
.Brake system inspection (or every 12 months,
whichever occurs first).
Maintenance II
.Perform all services described in Maintenance I.
.Steering and suspension inspection. Visual
inspection for damaged, loose, or missing parts
or signs of wear.
.Engine cooling system inspection. Visual
inspection of hoses, pipes, fittings, and clamps
and replacement, if needed.
.Windshield wiper blade inspection for wear,
cracking, or contamination and windshield and
wiper blade cleaning, if contaminated. See
Windshield and Wiper Blades
on page 6‑96.
Worn or damaged wiper blade replacement.
See Windshield Wiper Blade Replacement
on
page 6‑59.
.Body hinges and latches, key lock cylinders, any
folding seat hardware, and rear compartment,
hood, and console door hinges and latches
lubrication. See Recommended Fluids and
Lubricants
on page 7‑10. More frequent
lubrication may be required when vehicle is
exposed to a corrosive environment. Applying
silicone grease on weatherstrips with a clean cloth
makes them last longer, seal better, and not stick
or squeak.
.Restraint system component check. See Checking
the Restraint Systems on page 2‑60.
.Engine air cleaner filter inspection. See Engine Air
Cleaner/Filter on page 6‑27.
.Passenger compartment air filter replacement
(or every 12 months, whichever occurs first). More
frequent replacement may be required if vehicle is
driven regularly under dusty conditions.
Additional Required Services
At Each Fuel Stop
.Engine oil level check. See Engine Oilon
page 6‑19.
.Engine coolant level check. See Engine Coolanton page 6‑34.
