Automatic Transaxle Operation
There are several
different positions for
your shift lever.
PARK (P):This position locks your front wheels. It is
the best position to use when you start your engine
because your vehicle cannot 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.
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).
SeeShifting Into Park (P) (Automatic Transaxle)
on page 2-28. If you are pulling a trailer,
seeTowing a Trailer on page 4-40.
Ensure that 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) when the ignition key is in ON.
2-22

DRIVE (D):This position is for normal driving. If you
need more power for passing, and you are:
Going less than about 27 mph (43 km/h), push your
accelerator pedal about halfway down.
Going about 29 mph (47 km/h) or more, push your
accelerator pedal all the way down.
You will shift down to the next gear and have
more power.
SECOND (2):This position gives you more power than
DRIVE (D) but lower fuel economy. 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.
LOW (L):This position gives you even more power
than SECOND (2) but lower fuel economy. You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in LOW (L), the transaxle will not shift
into low gear until the vehicle is going slow enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
Overdrive Off
Your automatic transaxle
has an O/D (overdrive off)
button located on the
left side of the shift lever.
Press the O/D button to turn off overdrive. A light on
the instrument panel cluster will come on when
this feature is used. Press the button again to turn
overdrive back on. Then the light on the instrument
panel cluster will go off. SeeOverdrive Off Light
on page 3-40.
When you turn on your vehicle the overdrive will
automatically be on until you turn it off.
2-24

Torque Lock (Automatic Transaxle)
If you are parking on a hill and you do not shift
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 “torque lock.” 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, seeShifting Into Park (P)
(Automatic Transaxle) on page 2-28.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
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)
(Automatic Transaxle)
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 in ON. SeeAutomatic Transaxle Operation
on page 2-22.
If you cannot shift out of PARK (P), ease pressure on
the shift lever – push the shift lever all the way into
PARK (P) and release the shift lever button as
you maintain brake application. Then press the shift
lever button and move the shift lever into the gear
you wish.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into two
parts. If one part isn’t working, the other part can still
work and stop you. For good braking, though, you need
both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
If your vehicle has anti-lock brakes, this light should
come on when you turn the key to START. If it doesn’t
come on then, have it xed so it will be ready to
warn you if there’s a problem.
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
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.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. SeeAnti-Lock Brake
System Warning Light on page 3-33andTowing Your
Vehicle on page 4-37.
{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. United States

Anti-Lock Brake System
Warning Light
With the anti-lock brake system, the light 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 LOCK. 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 haveanti-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.
SeeBrake System Warning Light on page 3-32.
The anti-lock brake system warning light will come on
briey when you turn the ignition key to ON. This is
normal. If the light doesn’t come on then, have it xed
so it will be ready to warn you if there is a problem.
Low Tire Pressure Warning Light
This light should come on
briey as you start the
engine. It will then come on
only when a low tire
pressure condition exists.
SeeTire Pressure Monitor System on page 5-65for
more information. United StatesCanada

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.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That is perception time. Then you have to bring up your
foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is 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 three-fourths 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 is 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.
Avoid needless heavy braking. Some people drive in
spurts — heavy acceleration followed by heavy
braking — 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 are driving, brake
normally but do not 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 may have anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
If your vehicle has anti-lock brakes, this warning light on
the instrument panel will come on briey when you
start your vehicle.
When you start your engine, or when you 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 or pulses a little. This is normal.
If there is a problem with the anti-lock brake system,
the anti-lock brake system warning light will stay on.
SeeAnti-Lock Brake System Warning Light on
page 3-33.Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels. United States
Canada
4-7

The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and road
conditions. This can help you steer around the obstacle
while braking hard.
As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.If your vehicle has the vehicle stability control system,
it includes a brake assist system which provides
more powerful braking during a sudden, hard brake
application. See “Vehicle Stability Control System” under
Traction Control System (TCS) on page 4-9.
Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may feel
a slight brake pedal pulsation or notice some noise,
but this is normal.
