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.

The following procedure applies only to vehicles
with the console shift lever and is used to shift the
transaxle out of PARK (P) (if the vehicle needs to be
towed, for example) in case of a dead battery or low
voltage battery.
The console shift lock
release is located on the
front of the center console.
To access the shift lock release, do the following:
1. Verify that the shift lever is in PARK (P).
2. Pull up the rubber mat located on the front of the
center console.3. Remove the shift lock release hole cover by prying it
open with a small diameter tool.
4. Press the shift lock
release toward the
front of the vehicle
and hold it there.
5. While applying the brakes, shift the transaxle from
PARK (P) as needed.
6. Reinstall the shift lock release hole cover and the
rubber mat.

Tie a red cloth to your vehicle to alert police that
you've been stopped by the snow.

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.

CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough water. You don't
need to add water to the ACDelco
battery
installed in every new GM vehicle. But if a
battery has filler caps, be sure the right amount
of fluid is there. If it is low, add water to take
care of that first. If you don't, explosive gas could
be present.
Battery fluid contains acid that can burn you.
Don't get it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
CAUTION:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
5. Check that the jumper cables don't have loose or
missing insulation. If they do, you could get a shock.
The vehicles could also be damaged, too.
Before you connect the cables, here are some basic
things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative (
-) will go to a heavy,
unpainted metal engine part or to a remote
negative (
-) terminal if the vehicle has one.
Don't connect positive (+) to the negative (
-) or you
will get a short that would damage the battery and
maybe other parts, too. And don't connect the
negative (
-) cable to negative (-) terminal on the
dead battery because this can cause sparks.

6. Connect the red
positive (+) cable to
the remote positive (+)
terminal location on the
vehicle with the dead
battery. Use a remote
positive (+) terminal
if the vehicle has one.
7. Don't let the other end
touch metal. Connect it
to the positive (+)
terminal location of the
vehicle with the good
battery. Use a remote
positive (+) terminal if
the vehicle has one.
8. Now connect the
black negative (
-) cable
to the negative (
-)
terminal location of the
vehicle with the good
battery. Use a remote
negative (
-) terminal if
the vehicle has one.
Don't let the other end of the cable touch anything
until the next step. The other end of the negative (
-)
cable doesn't go to the dead battery. It goes to a
heavy, unpainted metal engine part or to a remote
negative (
-) terminal on the vehicle with the
dead battery.

5-8
9. Connect the other end of
the negative (
-) cable to
the negative (
-) terminal
location on the vehicle
with the dead battery.
Your vehicle has a remote
negative (
-) terminal
marked GND (
-)
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle with the dead battery.
If it won't start after a few tries, it probably
needs service.
NOTICE:
Damage to your vehicle may result from
electrical shorting if jumper cables are removed
incorrectly. To prevent electrical shorting, take
care that the cables don't touch each other or any
other metal period. The repairs wouldn't be
covered by your warranty.
