2006 CADILLAC STS washer fluid

Windshield Washer
K(Washer Fluid):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 uid 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.
{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.
If the uid in the windshield washer uid reservoir is
low, the message CHECK WASHER FLUID will appear
on the Driver Information Center (DIC) display. It will
take 60 seconds after the bottle is relled for this
message to turn off. For information on the correct
washer uid mixture to use, seeWindshield Washer
Fluid on page 5-40andRecommended Fluids and
Lubricants on page 6-12.
Headlamp Washer
Your vehicle may have headlamp washers. The
headlamp washers clear debris from the headlamp
lenses.
The headlamp washers are located to the inside of the
headlamps.
To wash the headlamps, press the washer button
located at the end of the windshield wiper lever.
Headlamps will be washed when the washer button is
pressed if two minutes have elapsed since the last
washer button press. If two minutes have not elapsed,
the headlamps will be washed every fourth washer
button press.

CHECK TIRE PRESSURE
This symbol appears with
the CHECK TIRE
PRESSURE message.
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message will display when one or more of
the vehicle’s tires are low or high. SeeDIC Controls
and Displays on page 3-74for information on checking
your vehicle’s tire pressures.
CHECK WASHER FLUID
This symbol appears with
the CHECK WASHER
FLUID message.
When this message displays, it means that your vehicle
is low on windshield washer uid. You should rell
the tank as soon as possible. SeeWindshield Washer
Fluid on page 5-40for more information.
CLEAN RADAR
When this message displays, it means that the Adaptive
Cruise Control system is disabled because the radar
is blocked and cannot detect vehicles in your path.
It may also activate during heavy rain or due to road
spray. To clean the system, see “Cleaning the System”
underAdaptive Cruise Control on page 3-19.

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 rst 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 nd 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 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?

Windshield Washer Fluid
What to Use
When you need windshield washer uid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a uid that has sufficient
protection against freezing.
Adding Washer Fluid
The CHECK WASHER FLUID message will appear
on the Driver Information Center (DIC) when the uid
level is low. SeeDIC Warnings and Messages on
page 3-79for more information.
Open the cap with the
washer symbol on it. Add
washer uid until the
tank is full. SeeEngine
Compartment Overview on
page 5-12for reservoir
location.Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions for
adding water.
Do not mix water with ready-to-use washer uid.
Water can cause the solution to freeze and
damage your washer uid tank and other parts
of the washer system. Also, water does not
clean as well as washer uid.
Fill your washer uid tank only three-quarters
full when it is very cold. This allows for
expansion if freezing occurs, which could
damage the tank if it is completely full.
Do not use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.
