9-16 Driving and Operating
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.{Caution
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.
{Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
See Add-On Electrical Equipment
on page 9-42.

9-18 Driving and Operating
It is possible to turn the radio back
on at any time after it has timed out
using the Power knob. The radio will
be functional for 10 minutes after the
last input (button press, knob turn)
to the radio is detected.
Shifting Into Park
(Automatic Transmission)
1. Hold the brake pedal down andset the parking brake. See
Parking Brake on page 9-26.
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.
It could overheat and catch fire.
It is 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.
Do not leave the vehicle when the
engine is running. 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,
always set the parking brake and
move the shift lever to P (Park).
See Shifting Into Park (Automatic
Transmission) on page 9-18. 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 the 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”previously 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 10-75.
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 2-8.
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.

Automatic
Transmission
P (Park): This position locks the
front wheels. It is the best position
to use when you start the engine
because the vehicle cannot move
easily.
{Warning
It is 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.
Do not leave the vehicle when the
engine is running. If you have left

9-26 Driving and Operating
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehiclesuddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Parking Brake
To set the parking brake, hold the
brake pedal down and pull up on the
parking brake lever. If the ignition is
on, the brake system warning light
will come on. See
Brake System
Warning Light on page 5-15.
To release the parking brake, hold
the brake pedal down. Pull the
parking brake lever up until you can
press the release button. Hold the
release button in as you move the
brake lever all the way down.

shift to a lower gear to maintain the
vehicle speed. When the brakes are
applied, cruise control will turn off.
Ending Cruise Control
There are three ways to end cruise
control:
.To disengage cruise control,
step lightly on the brake pedal or
clutch for manual transmission.
.Pressnon the steering wheel.
.To turn off cruise control, pressoon the steering wheel.
Erasing Speed Memory
The cruise control set speed is
erased from memory if the
obutton
is pressed or if the ignition is
turned off.
Driver Assistance
Systems
Forward Collision Alert
(FCA) System
For vehicles with this feature, read
the following section before using it.
The Forward Collision Alert (FCA)
system may help to avoid or reduce
the harm caused by front-end
crashes. FCA provides a flashing
red visual alert and beeps when
approaching a vehicle directly
ahead too quickly. FCA also
provides a visual alert if following
another vehicle much too closely.
The FCA display is on top of the
instrument panel to the right of the
steering wheel.
The forward-looking FCA camera
sensor is on the windshield ahead
of the rearview mirror. FCA detects
vehicles within a distance of
approximately 60 m (197 ft) and
operates at speeds above 40 km/h
(25 mph).
{Warning
FCA is a warning system and
does not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. FCA does not warn
of pedestrians, animals, signs,
guardrails, bridges, construction
barrels, or other objects. Be ready
to take action and apply the
brakes. For more information, see
Defensive Driving on page 9-2.
