2002 CADILLAC DEVILLE Differ

2-28
Automatic Transaxle Operation
The automatic transaxle may have a shift lever located
on either the steering column or on the console between
the seats.
There are several
different positions for
the shift lever.
Console Shifter
Column Shifter (Digital and Analog Cluster similar)

2-32
Performance Shifting (DTS Only)
When your vehicle detects a change in driving
conditions, it will automatically initiate the appropriate
performance shift mode. When this occurs, the gear
display on the instrument panel cluster will change to
indicate that the transaxle has shifted to a different gear.
For example, the gear display on the cluster may
indicate 3 or 2 even though the gearshift is still in
AUTOMATIC OVERDRIVE (
). Once the
performance shift mode ends, the gear display on the
instrument panel cluster will return to normal.
Shift Lock Release
This vehicle is equipped with an electric shift lock
release system. The shift lock release is designed to
do the following:

Prevent the ignition key from being removed unless
the shift lever is in PARK (P), and

prevent movement of the console shift lever
(DTS only) out of PARK (P) unless the ignition is
in a position other than OFF. The shift lock release is
always functional except in the case of a dead battery
or low voltage (less than 9 V) battery.If your vehicle has a dead battery or a battery with low
voltage, there is a procedure that will allow you to
override the shift lock release.
The following procedure allows the ignition to be turned
to OFF and for ignition key removal in case of a dead
battery or low voltage battery.
1. Verify that the shift lever is in PARK (P).
2. Locate the override
access slot underneath
the steering column
below the lock cylinder.
3. Remove the override access slot cap.
4. Insert a tool into the access slot, press in and hold.
5. Turn the ignition key to OFF.
6. Remove the tool from the slot.
7. Remove the key from the ignition.
8. Reinstall the override access slot cap.

Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange
or different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving over
high points on the road or over road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.
Running Your Engine While
You're Parked
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
ªEngine Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle
even if the fan is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO
-- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be a blizzard.
See ªBlizzardº in the Index.

2-51
Wiper-Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately six seconds. To operate, the Twilight
Sentinel

feature must be turned on. See ªTwilight
Sentinelº in the Index for more information.
When the exterior lamp control is in the off position or
in the parking lamp position and the wiper control is on
delay, LO or HI, the HEADLAMPS SUGGESTED
message will appear on the Driver Information
Center (DIC).
When the ignition is turned to OFF, the wiper
-activated
headlamps will immediately turn off. The wiper
-activated
headlamps will also turn off if the Twilight Sentinel or the
windshield wipers are turned off.
Lamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver's door is opened with the ignition off.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset. Fully
functional daytime running lamps are required on all
vehicles first sold in Canada.
The DRL system will make the low
-beam headlamps
come on at reduced intensity when the following
conditions are met:

It is still daylight and the ignition is on,

the exterior lamp control is in the off position and

the transaxle is not in PARK (P).

2-60
Compass Calibration
If after two seconds, the display does not show a
compass heading (N for North, for example), there may
be a strong magnetic field interfering with the compass.
Such interference may be caused by a magnetic antenna
mount, magnetic note pad holder or a similar magnetic
item. If the letter C should ever appear in the compass
window, the compass may need calibration.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display
reads a direction.
The compass can be placed in calibration mode by
pressing and holding the on/off button until a C is
shown in the compass display.Compass Variance
The mirror is set in zone eight upon leaving the factory.
It will be necessary to adjust the compass to compensate
for compass variance if you live outside zone eight.
Under certain circumstances, as during a long distance
cross
-country trip, it will be necessary to adjust for
compass variance. Compass variance is the difference
between earth's magnetic north and true geographic
north. If not adjusted to account for compass variance,
your compass could give false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance zone number
on the following zone map.
2. Press and hold the on/off button until a zone number
appears in the display.
