GMC 2007 Acadia - Manual (Page 131)

DRIVE (D): This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing, and you are:
• Going less than 35 mph (56 km/h), push
your accelerator pedal about halfway down.
• Going about 35 mph (56 km/h) or more, push
the accelerator all the way down.
Notice: If your vehicle seems to accelerate
slowly or not shift gears when you go faster,
and you continue to drive your vehicle that
way, you could damage the transmission. Have
your vehicle serviced right away. You can
drive in LOW (L) when you are driving less than
35 mph (56 km/h) and DRIVE (D) for higher
speeds until then.
LOW (L): This position gives you access to gear
ranges. This provides more engine braking but
lower fuel economy than DRIVE (D). You can use
it on very steep hills, or in deep snow or mud.
Electronic Range Select Mode
Electronic Range Selector (ERS) mode allows you
to choose the top-gear limit of the vehicle’s
transmission and the vehicle’s speed while driving
down hill or towing a trailer.
To use this feature, do the following:
1. Move the shift lever to LOW (L).
2. Press the plus/minus
button located on the
shift lever, to
increase or decrease
the gear range
available based
upon your current
driving conditions
and needs.
