2007 GMC SAVANA wiper blades

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.
Windshield Washer
L(Washer Fluid):There is a paddle marked
with the windshield washer symbol at the top of the
multifunction lever. To spray washer fluid on the
windshield, push the paddle. The wipers will
clear the window and then either stop or return to
your preset speed.
{CAUTION:
In freezing weather, do not use your
washer until the windshield is warmed.
Otherwise the washer uid can form ice
on the windshield, blocking your vision.

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.
{CAUTION:
Wet brakes can cause accidents. They
may not work as well in a quick stop and
may cause pulling to one side. You could
lose control of the vehicle.
After driving through a large puddle of
water or a car wash, apply your brake pedal
lightly until your brakes work normally.Driving too fast through large water puddles or
even going through some car washes can cause
problems, too. The water may affect your brakes.
Try to avoid puddles. But if you cannot, try to slow
down before you hit them.
Hydroplaning
Hydroplaning is dangerous. So much water can
build up under your tires that they can 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.
Hydroplaning does not happen often. But it can
if your tires do not have much tread or if the
pressure in one or more is low. It can happen if
a lot of water is standing on the road. If you
can see reflections from trees, telephone poles, or
other vehicles, and raindrops dimple the water’s
surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds.
There just is not a hard and fast rule about
hydroplaning. The best advice is to slow down
when it is raining.

Before changing lanes, check your mirrors.
Then use your turn signal.
Just before you leave the lane, glance quickly
over your shoulder to make sure there is not
another vehicle in your blind spot.
Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted.
Reduce your speed according to your
speedometer, not to your sense of motion.
After driving for any distance at higher speeds,
you may tend to think you are going slower than
you actually are.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?

information on wiper blade inspection.

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.

Windshield and Wiper Blades
If the windshield is not clear after using the
windshield washer, or if the wiper blade chatters
when running, wax, sap, or other material may
be on the blade or windshield.
Clean the outside of the windshield with a glass
cleaning liquid or powder and water solution.
The windshield is clean if beads do not form when
it is rinsed with water.
Grime from the windshield will stick to the wiper
blades and affect their performance. Clean
the blade by wiping vigorously with a cloth soaked
in full-strength windshield washer solvent. Then
rinse the blade with water.
Check the wiper blades and clean them as
necessary; replace blades that look worn.
Aluminum Wheels
Notice:If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or
cleaners that contain acid on aluminum or
chrome-plated wheels, you could damage the
surface of the wheel(s). The repairs would
not be covered by your warranty. Use
only GM-approved cleaners on aluminum or
chrome-plated wheels.
Keep the wheels clean using a soft clean cloth
with mild soap and water. Rinse with clean water.
After rinsing thoroughly, dry with a soft clean
towel. A wax may then be applied.
Notice:Using chrome polish on aluminum
wheels could damage the wheels. The repairs
would not be covered by your warranty.
Use chrome polish on chrome wheels only.
The surface of these wheels is similar to the
painted surface of the vehicle. Do not use strong
soaps, chemicals, abrasive polishes, abrasive
cleaners, cleaners with acid, or abrasive cleaning
brushes on them because the surface could
be damaged. Do not use chrome polish on
aluminum wheels.
