Cadillac 2004 CTS Owner's Manual page 94

Notice: Driving your vehicle if you notice that it is
moving slowly or not shifting gears as you
increase speed may damage the transmission. Have
your vehicle serviced right away. You can drive in
SECOND (2) when you are driving less than 35 mph
(55 km/h) and AUTOMATIC OVERDRIVE (D) for
higher speeds until then.
FOURTH (4): This position is also used for normal
driving. However, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D).
Here are examples for using FOURTH (4) instead of
AUTOMATIC OVERDRIVE (D).
•
When driving on hilly, winding roads.
•
When going down a steep hill.
THIRD (3): This position gives you more power. You
can use THIRD (3) 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.
2-28
If the shift lever is put into THIRD (3), the transmission
won't shift into THIRD (3) until the vehicle is moving
slowly enough.
SECOND (2): This position gives you even more power
than THIRD (3). You can use it on very steep hills, or
in deep snow or mud. (If the shift lever is put in
SECOND (2), the transmission won't shift into
SECOND (2) until the vehicle is going slowly enough).
FIRST (1): The transmission will automatically select
this gear when conditions indicate that more power
is needed. You cannot select this gear manually.
Notice: Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. If you are
stuck, do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
