Following break‐in, engine speed
and load can be gradually
increased.
Ignition Positions
The ignition switch has four different
positions.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.
The key must be fully extended to
start the vehicle.
To shift out of P (Park), turn the
ignition to ON/RUN and apply the
brake pedal.
A (STOPPING THE ENGINE/
LOCK/OFF): When the vehicle is
stopped, turn the ignition switch to
LOCK/OFF to turn the engine off.
Retained Accessory Power (RAP)
will remain active. See Retained
Accessory Power (RAP) on
page 9‑21 for more information.
This is the only position from which
the key can be removed. This locks
the steering wheel, ignition, and
automatic 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.
In an emergency, if the vehicle must
be shut off while driving:
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 neutral. This can be done while the vehicle is
moving. After shifting to neutral,
firmly apply the brakes and steer
the vehicle to a safe location.
3. Come to a complete stop. Shift to P (Park) with an automatic
transmission, or neutral with a
manual transmission. Turn the
ignition to LOCK/OFF.

4. Set the parking brake. SeeParking Brake on page 9‑31.
{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.
5. If the vehicle must be shut off while driving, turn the ignition to
ACC/ACCESSORY.
The ignition switch can bind in the
LOCK/OFF position with the wheels
turned off center. If this happens,
move the steering wheel from right
to left while turning the key to ACC/
ACCESSORY. If this does not work,
then the vehicle needs service. B (ACC/ACCESSORY):
This
position unlocks the steering wheel.
Some accessories can be used in
this position.
C (ON/RUN): The ignition switch
stays in this position when the
engine is running. This position can
be used to operate the electrical
accessories, as well as to display
some warning and indicator lights.
The battery could be drained if the
key is left in the ON/RUN position
with the engine off. The vehicle
might not start if the battery is
allowed to drain for an extended
period of time.
D (START): This position starts the
engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.
Starting the Engine
Place the transmission in the
proper gear.
Automatic Transmission
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
vehicle when it is already moving,
use N (Neutral) only.
Notice: Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped.
Manual Transmission
The shift lever should be in neutral
and the parking brake engaged.
Hold the clutch pedal down 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 key to
START. When the engine starts,
let go of the key. The idle speed
will go down as the engine
warms. Do not race the engine
immediately after starting it.
Allow the oil to warm up and
lubricate all moving parts.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking
for a few seconds or until the
vehicle starts. If the engine does
not start and the key is held in
START for many seconds,
cranking stops after 15 seconds
to prevent cranking motor
damage. To prevent gear
damage, this system also
prevents cranking if the engine is already running. Engine
cranking can be stopped by
turning the ignition switch to
ACC/ACCESSORY or
LOCK/OFF.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after 5 to 10 seconds, especially in
very cold weather (below −18°C
or 0°F), it could be flooded with
too much gasoline. Push the
accelerator pedal all the way to
the floor and hold it there as you
hold the key in START for a
maximum of 15 seconds. Wait at
least 15 seconds between each
try, to allow the cranking motor
to cool. When the engine starts,
let go of the key and accelerator. If the vehicle starts briefly but
then stops again, repeat the
procedure. This clears the extra
gasoline from the engine. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
until the oil warms up and
lubricates all moving parts.
Notice: The engine is designed to
work with the electronics in the
vehicle. If you add electrical parts
or accessories, 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.
Overrun Cut‐Off
When the vehicle is driven with a
gear engaged but the accelerator
released, the fuel supply is
automatically cut off to improve
fuel economy.

Leaving the Vehicle with the
Engine Running
{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, the vehicle must
be in P (Park) and the parking
brake set.
Release the button and check that
the shift lever cannot be moved out
of P (Park).
Torque Lock
Torque lock is when the weight
of the vehicle puts too much
force on the parking pawl in the
transmission. This happens when
parking on a hill and shifting the
transmission into P (Park) is not
done properly; then it is difficult to
shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park). To find
out how, see “Shifting Into Park”
listed previously.
If torque lock does occur, the
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).
Shifting out of Park
(Automatic Transmission)
This vehicle is equipped with
an electronic shift lock release
system. The shift lock release 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 release 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 10‑70
