wiper blades CHEVROLET EXPRESS CARGO VAN 2007 1.G Owners Manual

Windshield Wipers
You control the windshield wipers by turning the
band with the wiper symbol on it.
8(Mist):For a single wiping cycle, turn the
band to mist. Hold it there until the wipers start,
then let go. The wipers will stop after one wipe.
If you want more wipes, hold the band on
mist longer.
Delay:You can set the wiper speed for a long or
short delay between wipes. This can be very
useful in light rain or snow. Turn the band
to choose the delay time. The closer to the top of
the lever, the shorter the delay.
d(Low Speed):For steady wiping at low
speed, turn the band away from you to the first
solid band past the delay settings position.
For high-speed wiping, turn the band further, to
the second solid band past the delay settings. To
stop the wipers, move the band to off position.
a(High Speed):For high-speed wiping, turn the
band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.
Be sure to clear ice and snow from the wiper
blades before using them. If they’re frozen to the
windshield, carefully loosen or thaw them. If
your blades do become worn or damaged, get
new blades or blade inserts.

Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a
wet road, you cannot stop, accelerate, or turn as
well because your tire-to-road traction is not as
good as on dry roads. And, if your tires do not have
much tread left, you will get even less traction.It is always wise to go slower and be cautious if rain
starts to fall while you are driving. The surface may
get wet suddenly when your reflexes are tuned for
driving on dry pavement.
The heavier the rain, the harder it is to see.
Even if your windshield wiper blades are in good
shape, a heavy rain can make it harder to see
road signs and traffic signals, pavement markings,
the edge of the road, and even people walking.
It is wise to keep your wiping equipment in
good shape and keep your windshield washer fluid
reservoir filled with washer fluid. Replace your
windshield wiper inserts when they show signs of
streaking or missing areas on the windshield,
or when strips of rubber start to separate from
the inserts.

Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such
as after a day’s work — do not plan to make
too many miles that first part of the journey.
Wear comfortable clothing and shoes you can
easily drive in.
Is your vehicle ready for a long trip? If you keep
it serviced and maintained, it is ready to go.
If it needs service, have it done before starting
out. Of course, you will find experienced and
able service experts in GM dealerships all across
North America. They will be ready and willing
to help if you need it.Here are some things you can check before a trip:•Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
•Wiper Blades:Are they in good shape?
•Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
•Lamps:Are they all working? Are the
lenses clean?
•Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inflated to the recommended pressure?
•Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
•Maps:Do you have up-to-date maps?

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear and cracking. SeeScheduled Maintenance
(Gasoline Engine) on page 405for more
information on wiper blade inspection.
344

Replacement blades come in different types
and are removed in different ways. To remove
the type with a release clip, do the following:
1. Lift the wiper arm until it locks into a
vertical position.
2. Press down on the blade assembly pivot
locking tab. Pull down on the blade
assembly to release it from the wiper
arm hook.3. The insert has two notches at one end that
are locked by bottom claws of the blade
assembly. At the notched end, pull the insert
from the blade assembly.
4. To install the new wiper insert, slide the
notched end last, into the end with two blade
claws. Then slide the insert all the way through
the blade claws at the opposite end.
5. Make sure that the notches are locked by the
bottom claws. Make sure that all other claws
are properly locked on both sides of the
insert slot.
6. Put the blade assembly pivot in the wiper arm
hook. Pull it up until the pivot locking tab locks
in the hook slot.
7. Carefully lower the wiper arm and blade
assembly into the windshield.

Foreign materials such as calcium chloride and
other salts, ice melting agents, road oil and tar,
tree sap, bird droppings, chemicals from industrial
chimneys, etc., can damage your vehicle’s finish if
they remain on painted surfaces. Wash the vehicle
as soon as possible. If necessary, use non-abrasive
cleaners that are marked safe for painted surfaces
to remove foreign matter.
Exterior painted surfaces are subject to aging,
weather and chemical fallout that can take their
toll over a period of years. You can help to
keep the paint finish looking new by keeping your
vehicle garaged or covered whenever possible.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly
to keep their luster. Washing with water is all
that is usually needed. However, you may
use chrome polish on chrome or stainless steel
trim, if necessary.
Use special care with aluminum trim. To avoid
damaging protective trim, never use auto or
chrome polish, steam or caustic soap to clean
aluminum. A coating of wax, rubbed to high polish,
is recommended for all bright metal parts.
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

407

(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings, and clamps; replace with
genuine parts as needed. To help ensure proper
operation, a pressure test of the cooling system
and pressure cap and cleaning the outside of the
radiator and air conditioning condenser is
recommended at least once a year.
(d)Inspect wiper blades for wear, cracking,
or contamination. Clean the windshield and wiper
blades, if contaminated. Replace wiper blades
that are worn or damaged. See Windshield Wiper
Blade Replacement on page 344 and Windshield
and Wiper Blades on page 387 for more
information.
(e)Make sure the safety belt reminder light and
all belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced.
Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular
maintenance.(f)Lubricate all key lock cylinders, hood hinges,
hood prop rod pivot, hood latch assembly,
secondary latch, pivots, spring anchor, release
pawl, rear compartment hinges, latches, locks, fuel
door hinge, and any moving seat hardware. More
frequent lubrication may be required when exposed
to a corrosive environment. Applying silicone grease
on weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.
(g)Vehicles with Gross Vehicle Weight Rating
(GVWR) above 10,000 lbs (4 536 kg) only: Inspect
shields for damage or looseness. Adjust or
replace as required. This is a Noise Emission
Control Service. Applicable to vehicles sold in the
United States and recommended for vehicles
sold in Canada.
(h)Change automatic transmission uid and lter
if the vehicle is mainly driven under one or
more of these conditions:
-In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
-In hilly or mountainous terrain.
-When doing frequent trailer towing.
-Uses such as found in taxi, police,
or delivery service.
