Understanding gearshift positions
P (Park)
Always come to a
complete stop before
shifting into P (Park).
Make sure the gearshift
is securely latched in P
(Park). This locks the
transaxle and prevent
the front wheels from
rotating.
Always set the
parking brake
fully and make sure
the gearshift is
securely latched in P
(Park).
Never leave your vehicle unattended while it
is running.
R (Reverse)
With the gearshift in R
(Reverse), the vehicle
will move backward.
You should always
come to a complete
stop before shifting
into and out of R
(Reverse).

When to use D (Drive)
The D (Drive) position
eliminates the needless
shifting back and forth
between third and
fourth gears that your
vehicle may do when
driving on hilly terrain.
It also gives more
engine braking than
overdrive to slow your
vehicle on downgrades.
1 (First)
Use 1 (First) for when
added engine braking is
desired when
descending steep hills.
The automatic
transaxle will shift to
the proper gear to
ascend any grade
without any need to
shift to 1 (First).
Do not go faster than 61 km/h (38 mph) when in
this gear. You can upshift from 1 (First) to overdrive
at any time.
When parking, do not use the gearshift in
place of the parking brake. Always set the
parking brake fully and make sure that the
gearshift is securely latched in Park (P). Turn off
the ignition whenever you leave your vehicle.
Never leave your vehicle unattended while it is
running. If you do not take these precautions, your
vehicle may move unexpectedly and injure
someone.

Never use a tow bar that attaches to the
bumper when you tow your vehicle. This
could damage the bumper and cause an accident.
LUGGAGE RACK (IF EQUIPPED)
The rear crossbar can be adjusted to fit the item
being carried. The front crossbar does not move. Do
not load more than 44 kg (100 lbs.) on the luggage
rack.
To adjust cross-bar position:
1. Loosen the
thumbwheel at both
ends of the cross-bar.
2. Slide the cross-bar
to the desired location.
3. Tighten the thumbwheel at both ends of the
cross-bar.
Use adjustable tie down loops to secure the load.
