Yeah, less options

: "D, D3 and L" for the 5AT and "D, D4 and L" for the 6AT.
As per the buttons (as replied by
dusty179):
D3 button: To use D3, press the
D3 button when the shift lever is in
the ‘‘D’’ position. This position is similar
to D, except only the first three
gears are selected instead of all five.
Use D3 when towing a trailer in hilly
terrain, or to provide engine braking
when going down a steep hill. D3 can
also keep the transmission from
cycling between third and fourth
gears in stop-and-go driving.
Button D4 (Touring): To use D4, press the
D4 button when the shift lever is in
the ‘‘D’’ position. This position is
similar to D, except only the first
four gears are selected instead of all
six. Use D4 when towing a trailer in
hilly terrain, or to provide engine
braking when going down a steep hill.
D4 can also keep the transmission
from cycling between fourth and
fifth gears in stop-and-go driving.
L: To shift to Low, press
the release button on the front of the
shift lever. Use Low to make better
use of engine power when climbing,
and for maximum engine braking
when going down steep hills
