how the system operates.
{CAUTION
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing Your
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer/retailer and the service
manual have information about
servicing the vehicle and the airbag
system. To purchase a service
manual, seeService Publications
Ordering Information on page 7-15.
{CAUTION
For up to 10 seconds after the
ignition is turned off and the battery
is disconnected, an airbag can still
inate during improper service.
You can be injured if you are close
to an airbag when it inates.

engine. The vehicle will not start
if the clutch pedal is not all the
way down.
Features and Controls 2-17

Starting Procedure
1. With your foot off the accelerator
pedal, 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.
Operate the engine and
transmission gently to 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 will be stopped after15 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 5-10 seconds, especially in
very cold weather (below 0°F
or−18°C), it could be ooded
with too much gasoline. Push the
accelerator pedal all the way
to the oor and holding 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 briey 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/retailer. If you do not,
the engine might not perform
properly. Any resulting damage
would not be covered by the
vehicle warranty.
2-18 Features and Controls

Then, see if you can move the shift
lever away from P (Park) without
rst pressing the shift lever button.
If you can, it means that the
shift lever was not fully locked into
P (Park).
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 and 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 nd out how, see
“Shifting Into P (Park)” listed
previously.
If torque lock does occur, your
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, and
Prevent movement of the shift
lever out of P (Park) unless
the ignition is in ON/RUN or
ACC/ACCESSORY and the
regular brake pedal is applied.
The shift lock release is always
functional except in the case of
a 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. SeeJump Starting on
page 5-34for more information.To shift out of P (Park):
1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the
desired position.
If you still are unable to shift out
of P (Park):
