Warm-Up Shift - Oldsmobile 2004 Silhouette Owner's Manual

AUTOMATIC OVERDRIVE (D): This position is for
normal driving. If you need more power for passing,
and you are:
•
Going less than 35 mph (55 km/h), push your
accelerator pedal about halfway down.
•
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
You will shift down to the next gear and have
more power.
Notice: Driving your vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transaxle. 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.

Warm-Up Shift

Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35°F (2°C) or colder. You may notice
that the transaxle will shift at a higher vehicle speed until
the engine is warmed up. This is a normal condition
designed to provide heat to the passenger compartment
and defrost the windows more quickly. See Climate
Control System on page 3-28 for more information.

THIRD (3): This position is also used for normal driving,
but it offers more power and lower fuel economy than
AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):
•
When driving on hilly, winding roads
•
When towing a trailer, so there is less shifting
between gears
•
When going down a steep hill
SECOND (2): This position gives you more power but
lower fuel economy than THIRD (3). You can use
SECOND (2) 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.
Notice: Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transaxle. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (D) instead of SECOND (2).
