R (Reverse)
Use this position to drive the vehicle
backward.
Always come to a complete stop
before shifting into or out of R
(Reverse); you may damage the
transmission if you shift into R

The wheels and transmission are not
engaged. The vehicle will roll freely
even on the slightest incline unless
the parking brake or service brakes
are applied.

This is the normal driving position.
The transmission will automatically
shift through a 6-gear sequence, pro-
viding the best fuel economy and
power.
For extra power when passing anoth-
er vehicle or driving uphill, depress
the accelerator fully. The transmis-
sion will automatically downshift to
the next lower gear (or gears, as
appropriate).
The DRIVE MODE switch, located on
the shift lever console, allows the driv-
er to switch from NORMAL mode to
SPORT or ECO mode.
For more information, refer to
"Drive Mode Integrated Control
System" later in this chapter.
