WARNING (Continued)
.Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
.Do not leave an
unsecured child restraint
in the vehicle.
.Secure loose items in the
vehicle.
.Do not leave a seat folded
down unless needed.
Starting and
Operating
New Vehicle Break-In
Notice:The vehicle does not
need an elaborate break-in. But it
will perform better in the long run
if you follow these guidelines:
.Do not drive at any one
constant speed, fast or slow,
for the first 805 km (500 mi).
Do not make full-throttle
starts. Avoid downshifting to
brake or slow the vehicle.
.Avoid making hard stops for
the first 322 km (200 mi) or
so. During this time the new
brake linings are not yet
broken in. Hard stops with
new linings can mean
premature wear and earlier
replacement. Follow this
breaking-in guideline every
time you get new brake
linings. Following break‐in, engine speed
and load can be gradually
increased.
Ignition Positions
The ignition switch has four different
positions.
To shift out of P (Park), the ignition
must be in ON/RUN or ACC/
ACCESSORY and the regular brake
pedal applied.

9-16 Driving and Operating
A (STOPPING THE ENGINE/
LOCK/OFF):When the vehicle is
stopped, turn the ignition switch to
LOCK/OFF to turn the engine off.
This position locks the steering
wheel, ignition, and transmission.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to a
safe location. 3. Come to a complete stop, shift
to P (Park), and turn the ignition
to LOCK/OFF. On vehicles with
an automatic transmission, the
shift lever must be in P (Park) to
turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake on page 9‑28.
{WARNING
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
turn the ignition to ACC/
ACCESSORY. Notice:
Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer.
B (ACC/ACCESSORY): This is the
position in which you can operate
things like the radio and the
windshield wipers when the engine
is off.
C (ON/RUN): This position can be
used to operate the electrical
accessories and to display some
instrument panel cluster warning
and indicator lights. This position
can also be used for service and
diagnostics, and to verify the proper
operation of the malfunction
indicator lamp as may be required
for emission inspection purposes.
The switch stays in this position
when the engine is running.

9-18 Driving and Operating
Manual Transmission
The shift lever should be in Neutral
and the parking brake engaged.
Hold the clutch pedal to the floor
and start the engine. The vehicle
will not start if the clutch pedal is not
all the way down.
Starting Procedure
1. With your foot off the acceleratorpedal, turn the ignition to START.
When the engine cranks, let go
of the key. The idle speed will go
down as the engine gets warm.
The vehicle has a
Computer‐Controlled Cranking
System. It assists in starting
the engine and protects
components. If the ignition key
is turned to START and then
released when the engine
begins cranking, the engine
will continue cranking for a
few seconds or until the engine
starts. If the engine does not
start and the key is held in
START, cranking will be stopped
after 15 seconds to prevent damage. To prevent gear
damage, cranking is not allowed
if the engine is running. Engine
cranking can be stopped by
turning the ignition key to ACC/
ACCESSORY or LOCK/OFF.
Notice: Holding the key in START
for longer than 15 seconds at a
time will cause the battery to be
drained much sooner. And the
excessive heat can damage the
starter motor. Wait about
15 seconds between each try to
help avoid draining the battery or
damaging the starter.
2. If the engine does not start, wait about 15 seconds and try again.
Wait about 15 seconds between
each try.
When the engine has run about
10 seconds to warm up, the
vehicle is ready to be driven. Do
not run the engine at high speed
when it is cold.
If the weather is below freezing
(0°C or 32°F), let the engine run
for a few minutes to warm up. 3. If the engine still will not start,
or starts but then stops, it could
be flooded with too much
gasoline. Try pushing the
accelerator pedal all the way to
the floor and holding it there as
you hold the key in START for
about three seconds. If the
vehicle starts briefly but then
stops again, do the same thing,
but this time keep the pedal
down for five or six seconds.
This clears the extra gasoline
from the engine.
Notice: The engine is designed to
work with the electronics in the
vehicle. If electrical parts or
accessories are added, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.

Shifting Into Park
(Automatic Transmission)
{WARNING
It can be 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. 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, use the steps
that follow.
1. Hold the brake pedal down and set the parking brake. See
Parking Brake on page 9‑28 for
more information.
2. Move the shift lever into P (Park) by pressing the button on the
shift lever and pushing the lever
all the way toward the front of
the vehicle. 3. Turn the ignition key to
LOCK/OFF.
4. Remove the key and take it with you. If you can leave the vehicle
with the ignition key in your
hand, the vehicle is in P (Park).
Leaving the Vehicle with the
Engine Running (Automatic
Transmission)
{WARNING
It can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
if the shift lever is not fully in
P (Park) with the parking brake
firmly set. And, if you leave the
vehicle with the engine running, it
could overheat and even catch
fire. You or others could be
injured. Do not leave the vehicle
with the engine running. If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved
the shift lever into P (Park), hold the
brake pedal down. Then see if you
can move the shift lever away from
P (Park) without first pushing the
button on the shift lever. If you can,
it means that the shift lever was not
fully locked into P (Park).Torque Lock (Automatic
Transmission)
If you are parking on a hill and you
do not shift your transmission into
P (Park) properly, the weight of
the vehicle may put too much
force on the parking pawl in the
transmission. You may find it difficult
to pull the shift lever out of P (Park).
This is called
“torque lock.”
To prevent torque lock, set the
parking brake and then shift into
P (Park) properly before you leave

the driver seat. To find out how, see
“Shifting Into Park (Automatic
Transmission)”in this section.
When you are ready to drive, move
the shift lever out of P (Park) 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 transmission, so you can pull
the shift lever out of P (Park).
Shifting out of Park
(Automatic Transmission)
This vehicle is equipped with a shift
lock control. The shift lock control is
designed to:
.Prevent ignition key removal
unless the shift lever is in
P (Park) with the shift lever
button fully released.
.Prevent movement of the shift
lever out of P (Park) unless the
ignition is in ON/RUN and the
brake pedal is applied. The shift lock control is always
functional except in the case of an
uncharged or low voltage (less than
9‐volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. See
Jump Starting on
page 10‑74.
To shift out of P (Park):
1. Apply the brake pedal.
2. Turn the ignition to ON/RUN.
3. Press the shift lever button.
4. Move the shift lever to the
desired position.
If still unable to shift out of P (Park):
1. Fully release the shift lever button.
2. Hold the brake pedal down and press the shift lever button
again.
3. Move the shift lever to the desired position. If you still cannot move the shift
lever from P (Park), consult your
dealer or a professional towing
service.
The doors may lock when shifting
from P (Park). See
Automatic Door
Locks on page 2‑7.
Parking
If the vehicle has a manual
transmission, before getting out of
the vehicle, move the shift lever into
R (Reverse) if parking on a downhill
slope. On a level surface or an
uphill slope, use 1 (First) gear.
Firmly apply the parking brake. Turn
the wheels toward the curb for a
downhill slope, or away from the
curb for an uphill slope. Once the
shift lever has been placed into gear
with the clutch pedal pressed in,
turn the ignition key to LOCK/OFF,
remove the key, and release the
clutch.

Running the Vehicle
While Parked
It is better not to park with the
engine running. But if you ever have
to, here are some things to know.
{WARNING
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains carbon monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation. For
more information, seeEngine
Exhaust on page 9‑22.
{WARNING
It can be dangerous to get out of
the vehicle if the automatic
transmission 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
it is on fairly level ground, always
set the parking brake and move
the automatic transmission shift
lever to P (Park), or the manual
transmission shift lever to Neutral.
Follow the proper steps to be sure
the vehicle will not move. If the
vehicle has an automatic
transmission, see Shifting Into Park
(Automatic Transmission) on
page 9‑20.
