2001 CADILLAC ELDORADO ac sensor

2-25
OVERDRIVE (
): This position is for normal driving.
If you need more power for passing, and you're:

Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transaxle will shift down to the next gear and
have more power.
NOTICE:
If your vehicle seems to start up rather slowly, or
if it doesn't seem to shift gears as you accelerate,
something may be wrong with a transaxle system
sensor. If you drive very far that way, your
vehicle can be damaged. So if this happens, have
your vehicle serviced right away. Until then, you
can use SECOND (2) when you are driving less
than 35 mph (55 km/h) and OVERDRIVE (
)
for higher speeds.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than OVERDRIVE (
).
Here are examples for using THIRD (3) instead
of OVERDRIVE (
):

When driving on hilly, winding roads.

When towing a trailer, so there is less shifting
between gears.

When going down a steep hill.
SECOND (2): This position gives you more power than
Third (3). You can use SECOND (2) on hills. It can help
control your speed as you go down steep mountain
roads, but then you would also want to use your brakes
off and on.
NOTICE:
Don't shift into SECOND (2) unless you are going
slower than 65 mph (105 km/h), or you can
damage your engine.

OFF: Turn the band to OFF to turn off the wipers.
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 the blades do become
damaged, get new blades or blade inserts.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools.
Clear away snow or ice to prevent an overload.
Rainsense
II Wipers (ETC Only)
The moisture sensor is mounted on the interior side of
the windshield behind the rearview mirror and 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 a delay mode as well as
a continuous low or high speed depending 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.
The Rainsense system can be activated by turning the
wiper stalk to one of the five sensitivity levels within the
AUTO DELAY area. The AUTO DELAY 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 stalk away from you to the
higher levels of other AUTO DELAY settings increases
the sensitivity of the system and frequency of wipes. The
highest sensitivity setting, level five is closest to LO. 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. An initial wipe occurs when you
turn the ignition on as a reminder that Rainsense is active.
The windshield wipers also remain in a ªhigh parkº
position (when the wipers are stopped on the windshield
and are not in the normal park position), even when the
ignition is turned off.

2-37
NOTICE:
The wipers must be turned off when going
through a car wash to avoid damage.
The MIST and ªwashº cycles operate as normal and are
not affected by the Rainsense function. The Rainsense
system can be overridden at any time by manually
turning the wiper stalk to LO or HI speed.
NOTICE:
Do not place stickers or other items on the
exterior glass surface directly in front of the
moisture sensor. Doing this could cause the
moisture sensor to malfunction.
Windshield Washer
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
At the top of the turn signal/multifunction lever there is
a paddle with the word PUSH on it. To spray washer
fluid on the windshield, press and release this paddle.
The wipers will clear the windshield and either stop or
return to your preset speed. For more washer cycles,
press and hold the paddle.
LOW WASHER FLUID will be displayed on the Driver
Information Center (DIC) when the washer fluid reaches
a low level.

Light Sensor
The light sensor for the Daytime Running Lamps (DRL)
and the Twilight Sentinel is located in the center of the
front defogger grille. If you cover the sensor, it will read
ªdarkº and the lamps will come on.
Exterior Lighting Battery Saver
If the manual parking lamp control has been left on, the
exterior lamps will turn off approximately 10 minutes
after the ignition is turned to LOCK or ACCESSORY.
This protects against draining the battery in case you
have accidentally left the headlamps or parking lamps
on. If you need to purposely leave the lamps on for more
than 10 minutes with the ignition in LOCK or
ACCESSORY, turn the exterior lamps control knob off
and then back on. To delay the lamps from turning off,
see ªTwilight Sentinelº in the Index.

Interior Lamps
Instrument Panel
Intensity/Brightness Control
The digital displays automatically dim when it becomes
dark outside and your lights are on. When it's dark, the
brightness control can be manually adjusted by turning
the exterior lamps control knob counterclockwise to dim
and clockwise to brighten the lighting. The digital
displays automatically brighten when it becomes light
outside, although backlighting will remain active at the
selected brightness as long as the lights are on.
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door controls and to
the exterior lamps control knob when a door is opened
or if you press a remote keyless entry transmitter button.
Since the illuminated entry system has a photocell, this
means that it must be dark outside in order for the
courtesy lamps or backlighting to turn on. The courtesy
lamps turn off approximately 20 seconds after the last
door is closed or after the ignition is turned to RUN.
Parade Dimming
This feature prohibits the dimming of the instrument
panel lights during daylight while the headlamps are on.
This feature operates with the light sensor for the
Twilight Sentinel and is fully automatic. When the light
sensor reads darkness outside, the instrument panel
lights can be adjusted by turning the exterior lamps
control knob counterclockwise to dim and clockwise to
brighten lighting. Backlighting to the instrument panel
will turn on, regardless of light conditions.
Reading Lamps
The reading lamps are located either in the headliner or
above the windows if you have a sunroof. To turn them
on, turn the exterior lamps control knob all the way
clockwise. These lamps and the interior courtesy lamps
automatically come on when either door is opened and it
is dark outside. For manual operation, press the button
to turn them on. Press it again to turn them off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.

When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Your vehicle also has a Driver Information Center that
works along with the warning lights and gages. See
ªDriver Information Centerº in the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about 20 seconds,
then it will flash for about
70 seconds.
If the driver's belt is already buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag's electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see ªAir
Bagº in the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.

however, your vehicle will remain in the storage mode.
The ignition must be out of LOCK before the battery
guard is disabled.Comfort Controls and Radio System Personalization
These features allow both drivers to personalize their
own climate control settings as well as their radio
settings. For more information, see ªClimate Control
Personalizationº and ªRadio Personalizationº in
the Index.
Continuous Variable Road Sensing
Suspension (CVRSS) (ETC Only)
The CVRSS automatically adjusts the ride of your
vehicle. Automatic ride control is achieved through a
computer used to control and monitor the suspension
system. The controller receives input from various
sensors to determine the proper system response. If the
controller detects a problem within the system, the
Driver Information Center (DIC) will display a
SERVICE RIDE CONTROL message. If this message
