Automatic Transaxle Operation
There are several different positions for the shift lever.
PARK (P):This position
locks the front wheels. It's
the best position to use
when you start the engine
because your vehicle
can't move easily.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake ®rmly set. Your vehicle can roll.
CAUTION: (Continued)
CAUTION: (Continued)
Do not leave your 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 your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). See ªShifting Into Park (P)º in the
Index. If you are pulling a trailer, see ªTowing
a Trailerº in the Index.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transaxle
shift lock control system. You have to fully apply
your regular brakes before you can shift from PARK (P)
while the ignition key is in ON. If you cannot shift the
shift lever all the way into PARK (P), ease pressure on
the shift lever and push the shift lever all the way
into PARK (P) as you maintain brake application. Then
move the shift lever into the gear you wish. See
Shifting Out of Park (P) on page 2-34.

THIRD (3):This position is also used for normal driving,
however, it offers more power and lower fuel economy
than AUTOMATIC OVERDRIVE (
X).
Here are examples for using THIRD (3) instead of
AUTOMATIC OVERDRIVE (
X):
·When driving on hilly, winding roads.
·When going down a steep hill.
SECOND (2):This position gives you more power. You
can use SECOND (2) on hills. It can help control
your speed as you go down steep mountain roads, but
then you would also want to use your brakes off
and on.
Notice:Don't shift into SECOND (2) unless you are
going slower than 65 mph (105 km/h), or you can
damage your engine.
FIRST (1):This position gives you even more power
than SECOND (2). You can use it on very steep hills, or
in deep snow or mud.
If the traction control switch is off, your vehicle will not
go into FIRST (1) gear and the vehicle will accelerate
from stop more slowly. This can help in deep snow
or mud conditions. When the traction control is turned
off, a message will light up on the Driver Information
Center (DIC).
Notice:If your front wheels won't turn, don't try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transaxle. Also,
if you stop when going uphill, don't hold your
vehicle there with only the accelerator pedal. This
could overheat and damage the transaxle. Use your
brakes to hold your vehicle in position on a hill.
Performance Shift Display (STS Only)
When your vehicle detects a change in driving
conditions, it will automatically initiate the appropriate
performance shift mode. When this occurs, the
gear display on the instrument panel cluster will change
to indicate that the transaxle has shifted to a different
gear. For example, the gear display on the cluster may
indicate D, 3, 2, or 1 even though the gearshift lever
is still in AUTOMATIC OVERDRIVE (
X). Once
the performance shift mode ends, the gear display on
the instrument panel cluster will return to normal.
2-30

Reach under the driver's side of the instrument panel
and pull down on the manual release lever, which
is located behind the parking brake pedal. Pull down on
the yellow tab as shown by the arrow in the illustration.
If the parking brake does not release, you should
have your vehicle towed to your dealer for service.
Notice:Driving with the parking brake on can
cause your rear brakes to overheat. You may have
to replace them, and you could also damage
other parts of your vehicle.
If you are towing a trailer and are parking on a hill, see
Towing a Trailer on page 4-35.
Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake ®rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when you are on fairly level
ground, use the steps that follow. If you are
pulling a trailer, see ªTowing a Trailerº in
the Index.
2-32

Torque Lock
If you are parking on a hill and you don't shift your
transaxle into PARK (P) properly, the weight of
the vehicle may put too much force on the parking pawl
in the transaxle. You may ®nd it difficult to pull the
shift lever out of PARK (P). This is called ªtorque lock.º
To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave the
driver's seat. To ®nd out how, see
Shifting Into Park (P)
on page 2-32.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to take some of
the pressure from the parking pawl in the transaxle,
so you can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when
the ignition is ON. See
Automatic Transaxle Operation
on page 2-28.
If you cannot shift out of PARK (P), ease the pressure
on the shift lever. Push the shift lever all the way
into PARK (P) as you maintain brake application. Then
move the shift lever into the gear you want. If you
ever hold the pedal down but still can't shift out of
PARK (P), try the following:
1. Turn the ignition key to ACC. Open and close the
driver's door to turn off the RAP feature.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle ®xed as soon as you can.
2-34

Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This is helpful on long trips. Cruise
control does not work at speeds below about 25 mph
(40 km/h). When cruise control is on, you will see
a CRUISE light on the instrument panel cluster.
When you apply your brakes, the cruise control
shuts off.
{CAUTION:
·Cruise control can be dangerous where
you can not drive safely at a steady speed.
So, do not use your cruise control on
winding roads or in heavy traffic.
CAUTION: (Continued)
CAUTION: (Continued)
·
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause needless
wheel spinning, and you could lose control.
Do not use cruise control on slippery roads.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. See
Traction
Control System (TCS) on page 4-9. When road
conditions allow you to safely use it again, you may turn
the cruise control back on.
3-13

How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). When the system comes on,
the three lights on the display will illuminate to let you
know that the system is working. URPA senses
how close your vehicle is to an object. The distance is
determined by the four ultrasonic sensors located on the
rear bumper. When you shift into REVERSE (R) and
an object is detected, the following will occur in
sequence depending on the distance from the object:
·At 5 feet (1.5 m) a chime will sound and one
amber light will be lit;
·at 40 inches (1.0 m) both amber lights will be lit;
·at 20 inches (0.5 m) a continuous chime will
sound and all three lights (amber/amber/red) will
be lit; and
·at 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will ¯ash.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the
rear sensors to recognize an object, it must be within
operating range.If the URPA system is not functioning properly, the
display will ¯ash red, indicating that there is a problem.
The light will also ¯ash red while driving if a trailer is
attached to your vehicle, or a bicycle or object is on the
back of, or hanging out of your trunk. The light will
continue to ¯ash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h).
It may also ¯ash red if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper free of
mud, dirt, snow, ice and slush or materials such as
paint or the system may not work properly. If after
cleaning the rear bumper and driving forward at least
15 mph (25 km/h), the display continues to ¯ash red, see
your dealer. For cleaning instructions, see
Cleaning
the Outside of Your Vehicle on page 5-86.
It may also ¯ash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h).
Other conditions that may affect system performance
include things like the vibrations from a jackhammer or
the compression of air brakes on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots.
3-25

When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake doesn't fully
release. If it stays on after your parking brake is
fully released, it means you have a brake problem.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is on.
Driving with the brake system warning light on
can lead to an accident. If the light is still on
after you have pulled off the road and stopped
carefully, have the vehicle towed for service.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
¯oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. See
Towing
Your Vehicle on page 4-31.
Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light(s) will
come on when your engine
is started and may stay
on for several seconds.
That's normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you're driving, stop as soon
as possible and turn the ignition off. Then start the
engine again to reset the system. If the light still stays
on, or comes on again while you're driving, your vehicle
needs service. If the regular brake system warning
light isn't on, you still have brakes, but you don't have
anti-lock brakes. If the regular brake system warning
light is also on, you don't have anti-lock brakes
and there's a problem with your regular brakes. See
Brake System Warning and Parking Brake Indicator
Light on page 3-43.
The anti-lock brake system warning light should come
on brie¯y when you turn the ignition key to ON. If
the light doesn't come on then, have it ®xed so it will be
ready to warn you if there is a problem.
3-44

TRACTION SUSPENDED ± 56:This message displays
when the traction control system has been temporarily
shut off because your vehicle's brakes have overheated.
This message does not indicate a problem with your
vehicle's traction control system. After a few minutes,
the traction control system will be available again
and the TRACTION READY message will appear.
TRANS HOT IDLE ENGINE ± 112:This message
indicates that the transaxle ¯uid in your vehicle is too
hot. Stop and allow your vehicle to idle until it cools
down or until this message is removed.
TRUNK OPEN ± 24:This message indicates that the
trunk is open when the ignition is on.
TURN SIGNAL ON ± 20:If you drive your vehicle for
more than a mile with a turn signal on, this message will
appear as a reminder to turn off the turn signal. A
multiple chime will sound when this message is
displayed.
VEHICLE OVERSPEED ± 52:This message is
displayed when the vehicle speed exceeds a certain
limit as required by some export countries. A continuous
chime will sound when this message is displayed.Climate Controls and Radio System
Personalization
These features allow both drivers to personalize their
own climate control settings as well as their radio
settings. For more information, see
Climate Controls
Personalization on page 3-36andRadio Personalization
with Home and Away Feature on page 3-102.
The outside temperature is always available for display
if it has been selected for a DIC display when your
vehicle is running unless an overriding DIC message
appears. You can change the temperature from
Fahrenheit to Celsius by pressing the ENG/MET
(English/metric) button on the instrument panel. For
more information on the DIC, see
DIC Warnings
and Messages on page 3-56.
The electronic sensor can be affected by road or engine
heat during idling, slow driving or when the engine is
®rst started after a short trip. To ensure proper automatic
climate control operation, the outside air temperature
display may not update as quickly as expected. This is
to allow the air surrounding the outside temperature
sensor to be as close to the actual outside conditions as
possible. This is determined by how much time has
elapsed since the vehicle has been turned off and by
vehicle speed.
3-63

Control of a Vehicle
You have three systems that make your vehicle go
where you want it to go. They are the brakes, the steering
and the accelerator. All three systems have to do their
work at the places where the tires meet the road.
Sometimes, as when you are driving on snow or ice, it
is easy to ask more of those control systems than
the tires and road can provide. That means you can lose
control of your vehicle. Also see
Traction Control
System (TCS) on page 4-9.
Braking
Braking action involvesperception timeandreaction time.
First, you have to decide to push on the brake pedal.
That'sperception time.Then you have to bring up your
foot and do it. That'sreaction time.
Averagereaction timeis about 3/4 of a second. But
that's only an average. It might be less with one driver
and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination
and eyesight all play a part. So do alcohol, drugs and
frustration. But even in 3/4 of a second, a vehicle moving
at 60 mph (100 km/h) travels 66 feet (20 m). That
could be a lot of distance in an emergency, so keeping
enough space between your vehicle and others is
important.
And, of course, actual stopping distances vary greatly
with the surface of the road (whether it's pavement
or gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of
the vehicle and the amount of brake force applied.
4-6

Avoid needless heavy braking. Some people drive in
spurts Ð heavy acceleration followed by heavy
braking Ð rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.Anti-lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there's a problem with
the anti-lock brake system,
this warning light will
stay on. See
Anti-Lock
Brake System Warning
Light on page 3-44
