be in M (Manual Mode). The controls
are on the back of the steering wheel.
Tap the left control to downshift, and
the right control to upshift. A Driver
Information Center (DIC) message
indicates the gear the vehicle is in.

stop in snowy and icy conditions, you
may want to shift into 2 (Second) gear.

more traction on slippery surfaces.Drive Systems

AWD performance, and prevent
excessive wear to the clutch in the

spare tire with a full-size tire as soon
as possible. See Compact Spare Tire
