Cadillac 2009 DTS, Owner'S Manual

Page: 107 / 462

Notice: Driving the vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transmission. Have the
vehicle serviced right away. You can drive in
2 (Second) when you are driving less than 35 mph
(55 km/h) and D (Drive) for higher speeds until then.
D (Drive) can be used for towing. You may want to
shift the transmission to 3 (Third) or, if necessary, to a
lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions.
See Towing a Trailer on page 4-28 for more information.
3 (Third): This position is also used for normal
driving. However, it reduces vehicle speed more than
D (Drive) without using the brakes. You might choose
3 (Third) instead of D (Drive) when driving on hilly,
winding roads, when towing a trailer, so there is less
shifting between gears and when going down a
steep hill.
2 (Second): This position reduces vehicle speed more
than 3 (Third) without using the brakes. You can use
2 (Second) on hills. It can help control vehicle speed
as you go down steep mountain roads, but then
you would also want to use the brakes off and on.
Notice: Do not shift into 2 (Second) unless you are
going slower than 65 mph (105 km/h), or you can
damage the engine and/or transmission.
1 (First): This position reduces vehicle speed even
more than 2 (Second) without using the brakes. You can
use it on very steep hills, or in deep snow or mud.
If the shift lever is put in 1 (First) while the vehicle is
moving forward, the transmission will not shift into first
gear until the vehicle is going slowly enough.
Notice: Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by the vehicle warranty. If you are
stuck, do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
