wiper blades CADILLAC STS V 2007 1.G Owners Manual

Windshield Wipers
The lever on the right side of the steering column
operates the windshield wipers.
7(Mist):Pull the lever down and release it for
a single wiping cycle. The lever will return to its
original position. For more cycles, hold the
lever down before releasing it.
9(Off):Put the lever in this position to turn off
the wipers.
&(Delay):Put the lever in this position to set a
delay between wipes. Turn the delay adjustment
band to set the length of the delay.
x(Delay Adjustment):Use this band to set the
length of the delay between wipes when using the
delay feature. The closer you move the band
toward mist, the longer the delay. The windshield
wiper lever must be in delay for this feature to work.
6(Low Speed):Put the lever in this position
for slow, steady wiping cycles.
1(High Speed):Put the lever in this position
for rapid wiping cycles.
If the windshield wipers are in use for about
six seconds while you are driving, the exterior
lamps will come on automatically if the exterior
lamp control is in AUTO. SeeWiper Activated
Headlamps on page 215for more information.
Be sure to clear ice and snow from the wiper
blades before using them. If they’re frozen to the
windshield, gently loosen or thaw them. If the
blades do become damaged, install new blades.
For more information, seeWindshield Wiper Blade
Replacement on page 419.

Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.
Your vehicle (STS-V only) is equipped with a
feature that disables the wiper system when the
hood is open and your vehicle is stopped. Opening
the hood will automatically park the wipers if
they are not parked. This prevents the wipers from
interfering with hood operation. Be sure the
hood is not opened when you require the vehicle’s
wipers out of the park position, such as when
changing the wiper blades.
Rainsense™ II Wipers
If your vehicle has this feature, the moisture
sensor is mounted on the interior side of the
windshield behind the rearview mirror. It is used to
automatically operate the wipers by monitoring
the amount of moisture build-up on the windshield.
Wipes occur as needed to clear the windshield
depending on driving conditions and the sensitivity
setting. In light rain or snow, fewer wipes will
occur. In heavy rain or snow, wipes will occur more
frequently. The Rainsense™ wipers operate in adelay mode as well as a continuous low or high
speed as needed. If the system is left on for long
periods of time, occasional wipes may occur
without any moisture on the windshield. This is
normal and indicates that the Rainsense™ system
is activated.
To activate the Rainsense™ system, turn the
wiper band to delay mode and select one of the
four sensitivity levels indicated on the wiper stalk.
The position closest to off is the lowest sensitivity
setting, level one. This allows more rain or snow to
collect on the windshield between wipes. Turning
the wiper band away from you to higher sensitivity
levels increases the sensitivity of the system and
frequency of wipes. The highest sensitivity setting,
level four, is closest to low. A single wipe will occur
each time you turn the wiper stalk to a higher
sensitivity level to indicate that the sensitivity level
has been increased.
Notice:Going through an automatic car wash
with the wipers on can damage them. Turn
the wipers off when going through an
automatic car wash.

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 reexes 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 windshield wiping equipment
in good shape and keep your windshield washer
uid reservoir lled with washer uid. 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.

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 inated 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?
Highway Hypnosis
Is there actually such a condition as highway
hypnosis? Or is it just plain falling asleep at the
wheel? Call it highway hypnosis, lack of
awareness, or whatever.
There is something about an easy stretch of road
with the same scenery, along with the hum of the
tires on the road, the drone of the engine, and the
rush of the wind against the vehicle that can make
you sleepy. Do not let it happen to you! If it does,
your vehicle can leave the road in less than a
second, and you could crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with
a comfortably cool interior.
Keep your eyes moving. Scan the road ahead
and to the sides. Check your rearview mirrors
and your instruments frequently.
If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get
some exercise, or both. For safety, treat
drowsiness on the highway as an emergency.

Windshield Replacement
Keep in mind that your windshield is part of the
Head-Up Display (HUD) system. If you ever have
to get your windshield replaced, be sure to get
one that is designed for HUD or your HUD image
may look blurred or out of focus.
Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear or cracking. SeeScheduled Maintenance
on page 505.
It’s a good idea to clean or replace the wiper
blade assembly on a regular basis or when worn.
For proper windshield wiper blade length and
type, seeNormal Maintenance Replacement Parts
on page 518.

STS-V models will automatically move the
windshield wipers to the park position if the hood
is open. Make sure the hood is closed before
replacing your windshield wiper blades.
To replace the wiper blade assembly, do the
following:
1. Pull the windshield wiper assembly away from
the windshield.
2. Squeeze the tabs on each side of the wiper
blade assembly and slide the assembly off
the end of the wiper arm.3. Replace the blade assembly with a new one.
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 your
warranty. Do not allow the wiper blade arm to
touch the windshield.
4. Repeat the steps for the other wiper.

Finish Care
Occasional waxing or mild polishing of the vehicle
by hand may be necessary to remove residue
from the paint nish. Approved cleaning products
can be obtained from your dealer. SeeVehicle
Care/Appearance Materials on page 484.
Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint
nish may damage it. Use only non-abrasive
waxes and polishes that are made for a
basecoat/clearcoat paint nish on your vehicle.
The vehicle has a basecoat/clearcoat paint
nish. The clearcoat gives more depth and gloss
to the colored basecoat. Always use waxes
and polishes that are non-abrasive and made for a
basecoat/clearcoat paint nish.
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 the vehicle’s
nish 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. To help keep the
paint nish looking new, keep the vehicle in a
garage or covered whenever possible.
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.

Maintenance Footnotes
†The U.S. Environmental Protection Agency or
the California Air Resources Board has determined
that the failure to perform this maintenance item
will not nullify the emission warranty or limit
recall liability prior to the completion of the
vehicle’s useful life. We, however, urge that all
recommended maintenance services be performed
at the indicated intervals and the maintenance
be recorded.
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang,
etc. Inspect disc brake pads for wear and rotors for
surface condition. Inspect other brake parts,
including calipers, parking brake, etc.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts or signs of wear. Inspect power steering lines
and hoses for proper hook-up, binding, leaks,
cracks, chang, etc.(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings, and clamps; replace with
genuine GM 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)Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn
or damaged or that streak or miss areas of
the windshield.
(e)Make sure the safety belt reminder light and all
your 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.
