Driving and Operating 9-33
Automatic
Transmission
The vehicle has a shift lever on the
steering column.
It features an electronic shift
position indicator within the
instrument cluster. This display is
powered anytime the shift lever is
capable of being moved out of
P (Park). This means that if the
ignition is turned off, but not in
LOCK/OFF, there will be a small
current drain on the battery which
could discharge the battery over a
period of time. If you need to leave
the key in the ignition but not in
LOCK/OFF for an extended period,
it is recommended that youdisconnect the battery cable from
the battery to prevent discharging
the battery.
There are several different positions
for the shift lever.
P (Park):
This position locks the
rear wheels. It is the best position to
use when you start the engine
because the vehicle cannot move
easily.
{WARNING
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running unless you
have to. If you have left the
engine running, the vehicle can
move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
(Continued)
WARNING (Continued)
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park (Automatic
Transmission) on page 9‑28.
If you are pulling a trailer, see
Driving Characteristics and
Towing Tips on page 9‑54.
Make sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. You must fully apply the
brake pedal before you can shift
from P (Park) when the ignition key
is in ON/RUN. If you cannot shift out
of P (Park), ease pressure on the
shift lever by pushing the shift lever
all the way into P (Park) as you
maintain brake application. Then
move the shift lever into another
gear. See Shifting out of Park
(Automatic Transmission) on
page 9‑30.

9-34 Driving and Operating
R (Reverse):Use this gear to
back up.
Notice: Shifting to R (Reverse)
while the vehicle is moving
forward could damage the
transmission. The repairs would
not be covered by the vehicle
warranty. Shift to R (Reverse) only
after the vehicle is stopped.
To rock your vehicle back and forth
to get out of snow, ice, or sand
without damaging the transmission,
see If the Vehicle Is Stuck on
page 9‑16.
N (Neutral): In this position, the
engine does not connect with the
wheels. To restart the engine when
the vehicle is are already moving,
use N (Neutral) only.
{WARNING
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
(Continued)
WARNING (Continued)
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Notice: Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
D (Drive): This position is for
normal driving. It provides the best
fuel economy. If you need more
power for passing, and you are:
.Going less than about 55 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 55 km/h (35 mph) or
more, push the accelerator all
the way down.
The transmission will shift down
to the next gear and the vehicle
will have more power.
Downshifting the transmission in
slippery road conditions could result
in skidding, see “Skidding”under
Loss of Control on page 9‑5.
3 (Third): This position is also used
for normal driving. However, it
reduces vehicle speed more than
D (Drive) without using the brakes.
You might choose 3 (Third) instead
of D (Drive) when driving on hilly,
winding roads, or when towing a
trailer, so there is less shifting
between gears and when going
down a steep hill.
2 (Second): This position reduces
vehicle speed even more than
3 (Third) without using the brakes.
You can use 2 (Second) to help
control vehicle speed on steep

Driving and Operating 9-35
mountain roads, but then you would
also want to use the brakes off
and on.
1 (First):This position reduces
vehicle speed even more than
2 (Second) without using the brakes.
You can use it on very steep hills,
or in deep snow or mud. If the shift
lever is put in 1 (First) while the
vehicle is moving forward, the
transmission will not shift into
first gear until the vehicle is going
slowly enough.
Notice: Spinning the tires or
holding the vehicle in one
place on a hill using only the
accelerator pedal may damage
the transmission. The repair will
not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.Manual Transmission
This is your shift pattern.
Here is how to operate the manual
transmission:
1 (First): Press the clutch pedal
and shift into 1 (First). Then, slowly
let up on the clutch pedal as you
slowly press down on the
accelerator pedal. You can shift into 1 (First) when
you are going less than 30 km/h
(20 mph). If you have come to a
complete stop and it is hard to shift
into 1 (First), put the shift lever in
Neutral and let up on the clutch.
Then press the clutch pedal back
down and shift into 1 (First).
2 (Second):
Press the clutch pedal
as you let up on the accelerator
pedal and shift into 2 (Second).
Then, slowly let up on the
clutch pedal as you press the
accelerator pedal.
3 (Third), 4 (Fourth) and 5 (Fifth):
Shift into 3 (Third), 4 (Fourth) and
5 (Fifth) the same way you do for
2 (Second). Slowly let up on the
clutch pedal as you press the
accelerator pedal.
To stop, let up on the accelerator
pedal and press the brake pedal.
Just before the vehicle stops, press
the clutch pedal and the brake
pedal, and shift to Neutral.

9-36 Driving and Operating
Neutral:Use this position when
you start or idle the engine.
R (Reverse): To back up, press the
clutch pedal. After the vehicle stops,
shift into R (Reverse). Slowly let up
on the clutch pedal as you press the
accelerator pedal. If it is hard to
shift, let the shift lever return to
Neutral and release the clutch
pedal. Then press the clutch again
and shift into R (Reverse). Do not
attempt to shift into 5 (Fifth) prior to
shifting into R (Reverse). The
transmission has a lock out feature
which prevents a 5 (Fifth) gear to
R (Reverse) gear shift. Notice:
Shifting to R (Reverse)
while the vehicle is moving
forward could damage the
transmission. The repairs would
not be covered by the vehicle
warranty. Shift to R (Reverse) only
after the vehicle is stopped.
Use R (Reverse), along with the
parking brake, for parking the
vehicle.Shift Speeds
{WARNING
If you skip a gear when you
downshift, you could lose control
of the vehicle. You could injure
yourself or others. Do not shift
down more than one gear at a
time when you downshift.

7. Shift the transmission to the desired position.Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that
helps prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
on page 5‑16. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
