Buick 2009 Enclave - Manual (Page 102)

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): This position is for normal driving. It
provides the best fuel economy. If more power is needed
for passing, and the vehicle is:
• Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
• Going about 35 mph (55 km/h) or more, push the
accelerator pedal all the way down.
By doing this, the vehicle will automatically shift
down to the next gear and have more power.
Downshifting the transmission in slippery road conditions
could result in skidding. See Skidding under Loss of
Control on page 4-12.
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.
Notice: Driving in 2 (Second) for more than 25 miles
(40 km) or at speeds over 55 mph (90 km/h) may
damage the transmission. Also, shifting into
2 (Second) at speeds above 65 mph (105 km/h) can
cause damage. Drive in 3 (Third) or D (Drive)
instead of 2 (Second).
2 (Second): This position reduces vehicle speed even
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, while
using the brakes off and on.
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.
