2001 CADILLAC CATERA automatic transmission

2-49 Cornering Lamps
The cornering lamps come on when the headlamps
or parking lamps are on and you signal a turn.
They provide more light for cornering.
Twilight Sentinel

This feature is located
below the lamp dial on the
left side of the instrument
panel. It automatically turns
the parking lamps and
low
-beam headlamps on
and off by sensing how
dark it is outside.
To operate the Twilight Sentinel, the ignition must be in
ON or START and the Twilight Sentinel must be turned
on by pressing the OFF button (the indicator light in the
button will be off when the Twilight Sentinel is
activated). If the system senses it is dark enough outside,
the lamps will turn on. The lamps turn off when the
system detects that it is bright enough outside.If you turn the knob all the way up, the lamps will
remain on for about three minutes after the ignition has
been turned to OFF or LOCK. If you turn the knob
all the way down, the lamps will go off quickly.
You can adjust the delay time from a few seconds
up to three minutes.
To turn the Twilight Sentinel off, press the OFF button
again. The indicator light in the button will be on. This
lets the driver know that the system has been turned off.
The Twilight Sentinel also turns off if the ignition is
turned to OFF or to LOCK.This light in the instrument
panel cluster will come on if
the ignition is on and:

the headlamps have not been manually turned on,

the Twilight Sentinel senses it is dark
enough outside,

the Twilight Sentinel is OFF and

the transmission is not in PARK (P).

If you continue to drive with a loose fuel cap, the
diagnostic system in your vehicle can determine if the
fuel cap has been left off or improperly installed. A
loose or missing fuel cap will allow fuel to evaporate
into the atmosphere. If this happens, the CHECK
ENGINE light may come on. For more information, see
ªMalfunction Indicator Lampº earlier in this section.
Automatic Transmission Warning Light
(If Equipped)
This light comes on briefly
when the ignition is turned
on. If the light remains on
or lights up while driving,
there may be a fault in the
automatic transmission.
Have your vehicle serviced.
Leveling Indicator Light
This light comes on steady
when the rear load level in
your vehicle changes.Do not drive your vehicle when this light is on.
The rear of your vehicle is too low and part of the
body or the rear axle may be damaged when driving
over bumpy roads. When the light goes out, leveling
is complete. This procedure is automatic
-- you don't
have to do anything.
If the light comes on flashing, there may be a problem
with the leveling system. You should reduce your
vehicle speed and have your vehicle serviced soon.
Brake Pad Wear Indicator Light
This light comes on when
the brake pads on your
vehicle have significantly
worn. The pads will have to
be replaced, so have your
vehicle serviced soon.

4-32 Electronic Level Control
This feature keeps the rear of your vehicle level as the
load changes. It's automatic
-- you don't need to
adjust anything.
Towing a Trailer
CAUTION:
If you don't use the correct equipment and drive
properly, you can lose control when you pull a
trailer. For example, if the trailer is too heavy,
the brakes may not work well
-- or even at all.
You and your passengers could be seriously
injured. You may also damage your vehicle; the
resulting repairs would not be covered by your
warranty. Pull a trailer only if you have followed
all the steps in this section. Ask your dealer for
advice and information about towing a trailer
with your vehicle.
Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify what the
vehicle trailering capacity is for your vehicle, you
should read the information in ªWeight of the Trailerº
that appears later in this section. But trailering is
different than just driving your vehicle by itself.
Trailering means changes in handling, durability and
fuel economy. Successful, safe trailering takes correct
equipment, and it has to be used properly.
That's the reason for this part. In it are many
time
-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers. So please read this section carefully
before you pull a trailer.
Load
-pulling components such as the engine,
transmission, rear axle, wheel assemblies and tires are
forced to work harder against the drag of the added
weight. The engine is required to operate at relatively
higher speeds and under greater loads, generating extra
heat. What's more, the trailer adds considerably to wind
resistance, increasing the pulling requirements.

4-38 Parking on Hills
CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can
be injured, and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply the regular brakes, but do not shift
into PARK (P).
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
PARK (P) firmly and apply the parking brake.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:

Start your engine;

Shift into a gear; and

Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule booklet for
more on this. Things that are especially important in trailer
operation are automatic transmission fluid (don't overfill),
engine oil, axle lubricant, drive belt, cooling system and
brake system. If you're trailering, it's a good idea to
review this information before you start your trip.
Check periodically to see that all hitch nuts and bolts are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.

Automatic Transmission Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take your vehicle to the dealership
service department and have it repaired as soon as
possible. You may also have your fluid level checked
by your dealer or service center when you have your
oil changed.
Change both the fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:

In heavy city traffic where the outside temperature
regularly reaches 90F (32C) or higher.

In hilly or mountainous terrain.

When doing frequent trailer towing.

Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.NOTICE:
We recommend you use only fluid labeled
DEXRON-III, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than
DEXRON
-III is not covered by your new
vehicle warranty.

When to Check Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant. See ªPeriodic Maintenance
Inspectionsº and ªScheduled Maintenance Servicesº in
the Maintenance Schedule booklet.
