AUTOMATIC TRANSMISSION
Do not leave the key fob in or near the
vehicle, or in a location accessible to chil-
dren, and do not leave a vehicle equipped
with Keyless Enter-N-Go in the ACC or ON/
RUN mode. A child could operate power
windows, other controls, or move the
vehicle.
Be sure the parking brake is fully disen -
gaged before driving; failure to do so can
lead to brake failure and a collision.
Always fully apply the parking brake when
leaving your vehicle or it may roll and cause
damage or injury. Also, be certain to leave
the transmission in PARK. Failure to do so
may cause the vehicle to roll and cause
damage or injury.
CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake
system malfunction is indicated. Have the
brake system serviced by an authorized
dealer immediately.
WARNING!

WARNING!
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accel -
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle always come to a complete stop,
then apply the parking brake, shift the
transmission into PARK, turn the engine
OFF, and remove the ignition key. Once the
key is removed, the transmission is locked
in PARK, securing the vehicle against
unwanted movement.
When leaving the vehicle, always remove
the ignition key from the vehicle and lock
the vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the transmission gear
selector.
Do not leave the ignition key in or near the
vehicle (or in a location accessible to chil -
dren). A child could operate power
windows, other controls, or move the
vehicle.

96STARTING AND OPERATING
NOTE:
You must press and hold the brake pedal while
shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park
Interlock which requires the transmission to be
in PARK before the ignition can be turned to the
LOCK/OFF (key removal) position. The key can
only be removed from the ignition when the igni -
tion is in the LOCK/OFF position, and once
removed the transmission is locked in PARK. NOTE:
If a malfunction occurs, the system will trap the
key in the ignition to warn you that this safety
feature is inoperable. The engine can be started
and stopped but the key cannot be removed
until you obtain service.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmis
-
sion Shift Interlock System (BTSI) that holds the
transmission gear selector in PARK unless the
brakes are applied. To shift the transmission
out of PARK, the ignition must be turned to the
ON/RUN mode (engine running or not), and the
brake pedal must be pressed.
NOTE:
Swivel seats that are unlocked can also prevent
the transmission gear selector from being
moved out of the PARK position. To shift the
transmission out of the PARK position the first
time after cranking is allowed, ensure swivel
seats are locked in the forward facing position.
Six-Speed Automatic Transmission
The transmission gear position display (located
in the instrument cluster) indicates the trans -
mission gear range. You must press the brake
pedal to move the gear selector out of PARK
(Refer to “Brake/Transmission Shift Interlock
System” in this section). To drive, move the gear
selector from PARK or NEUTRAL to the DRIVE
position.
The electronically-controlled transmission
provides a precise shift schedule. The transmis -
sion electronics are self-calibrating; therefore,
the first few shifts on a new vehicle may be
somewhat abrupt. This is a normal condition,
and precision shifts will develop within a few
hundred miles (kilometers).
Gear SelectorCAUTION!
Shift into or out of PARK or REVERSE only
after the vehicle has come to a complete
stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
Before shifting into any gear, make sure
your foot is firmly pressing the brake pedal.

20_VF_OM_EN_US_t.book Page 96

STARTING AND OPERATING97
(Continued)
Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on
the brake pedal when shifting between these
gears.
The transmission gear selector provides PARK,
REVERSE, NEUTRAL, DRIVE, and Electronic
Range Select (ERS) shift positions. Manual
downshifts can be made using the ERS shift
control. Moving the gear selector into the ERS
(-/+) position (beside the DRIVE position) acti -
vates ERS mode, displays the current gear in
the instrument cluster, and prevents automatic
upshifts beyond this gear. In ERS mode,
toggling the gear selector forward (-) or rear -
ward (+) will change the highest available gear.
Refer to "Electronic Range Select (ERS) Opera -
tion" in this section for further information.
NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position (when
pushed forward) it is probably in the ERS (+/-)
position (beside the DRIVE position). In ERS
mode, the transmission gear limit (1, 2, 3, etc.)
is displayed in the instrument cluster. Move the gear selector to the right (into the DRIVE [D]
position) for access to PARK, REVERSE, and
NEUTRAL.
Gear Ranges
Do not depress the accelerator pedal when
shifting from PARK or NEUTRAL into another
gear range.
NOTE:

After selecting any gear range, wait a moment
to allow the selected gear to engage before
accelerating. This is especially important when
the engine is cold.
PARK (P)
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never attempt to use
PARK while the vehicle is in motion. Apply the
parking brake when exiting the vehicle in this
range.
When parking on a level surface, you may shift
the transmission into PARK first, and then apply
the parking brake. When parking on a hill, apply the parking brake
before shifting the transmission to PARK, other
-
wise the load on the transmission locking mech -
anism may make it difficult to move the gear
selector out of PARK. As an added precaution,
turn the front wheels toward the curb on a
downhill grade, and away from the curb on an
uphill grade.
When exiting the vehicle, always:
Apply the parking brake.
Shift the transmission into PARK.
Turn the engine OFF.
Remove the ignition key.
WARNING!
Never use the PARK position as a substi -
tute for the parking brake. Always apply the
parking brake fully when exiting the vehicle
to guard against vehicle movement and
possible injury or damage.

98STARTING AND OPERATING
(Continued)
The following indicators should be used to
ensure that you have engaged the transmission
into the PARK position:
When shifting into PARK, firmly move the
gear selector all the way forward and to the
left until it stops and is fully seated.
Look at the transmission gear position
display and verify that it indicates the PARK
position (P).
With the brake pedal released, verify that the
gear selector will not move out of PARK.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the gear selector out of PARK with the
brake pedal released. Make sure the trans -
mission is in PARK before exiting the
vehicle.
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accel -
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle always come to a complete stop,
then apply the parking brake, shift the
transmission into PARK, turn the engine
OFF, and remove the ignition key. Once the

(Continued)

CAUTION!
Before moving the transmission gear
selector out of PARK, you must turn the igni -
tion to the ON/RUN mode, and also press
the brake pedal. Otherwise, damage to the
gear selector could result.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range,
as this can damage the drivetrain.

20_VF_OM_EN_US_t.book Page 98

STARTING AND OPERATING99
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has
come to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for
prolonged periods with the engine running. The
engine may be started in this range. Apply the
parking brake and shift the transmission into
PARK if you must exit the vehicle.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest
upshifts and downshifts, and the best fuel
economy. The transmission automatically
upshifts through all forward gears. The DRIVE
position provides optimum driving characteris -
tics under all normal operating conditions. When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, trav
-
eling into strong head winds, or while towing a
heavy trailer), select TOW/HAUL mode or use
the Electronic Range Select (ERS) shift control
(refer to “Electronic Range Select (ERS) Opera -
tion” in this section for further information) to
select a lower gear range. Under these condi -
tions, using a lower gear range will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
During cold temperatures, transmission opera -
tion may be modified depending on engine and
transmission temperature as well as vehicle
speed. This feature improves warm up time of
the engine and transmission to achieve
maximum efficiency. Engagement of the torque
converter clutch is inhibited until the transmis -
sion fluid is warm refer to the “Note” under
“Torque Converter Clutch” in this section.
During extremely cold temperatures (-16°F
[-27°C] or below), operation may briefly be
limited to third gear only. Normal operation will
resume once the transmission temperature has
risen to a suitable level.WARNING!

Do not coast in NEUTRAL and never turn off
the ignition to coast down a hill. These are
unsafe practices that limit your response to
changing traffic or road conditions. You might
lose control of the vehicle and have a collision.

CAUTION!

Towing the vehicle, coasting, or driving for any
other reason with the transmission in
NEUTRAL can cause severe transmission
damage.

Refer to “Recreational Towing” in “Starting
And Operating” and “Towing A Disabled
Vehicle” in “In Case Of Emergency” for further
information.

100STARTING AND OPERATING
Transmission Limp Home Mode
Transmission function is monitored electroni -
cally for abnormal conditions. If a condition is
detected that could result in transmission
damage, Transmission Limp Home Mode is acti -
vated. In this mode, the transmission remains
in third gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Transmission
Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service
without damaging the transmission. In the event of a momentary problem, the trans
-
mission can be reset to regain all forward gears
by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the trans -
mission will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible convenience.
Your authorized dealer has diagnostic equip -
ment to assess the condition of your transmis -
sion.
If the transmission cannot be reset, authorized
dealer service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear. For example, if you set the transmission
gear limit to 4 (fourth gear), the transmission
will not shift above fourth gear, but will shift
through the lower gears normally.
You can switch between DRIVE and ERS mode
at any vehicle speed. When the gear selector is
in the DRIVE position, the transmission will
operate automatically, shifting between all
available gears. Moving the gear selector to the
ERS position (beside DRIVE) will activate ERS
mode, display the current gear in the instru -
ment cluster, and set that gear as the top avail -
able gear. Once in ERS mode, moving the gear
selector forward (-) or rearward (+) will change
the top available gear.
To exit ERS mode, simply return the gear
selector to the DRIVE position.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the vehicle
could skid, causing a collision or personal
injury.

20_VF_OM_EN_US_t.book Page 100

STARTING AND OPERATING101
NOTE:
To select the proper gear position for maximum
deceleration (engine braking), move the gear
selector into the ERS position, then tap it
forward (-) repeatedly as the vehicle slows. The
transmission will shift to the range from which
the vehicle can best be slowed down.Overdrive Operation
The automatic transmission includes an elec -
tronically controlled Overdrive (sixth gear). The
transmission will automatically shift into Over -
drive if the following conditions are present:
The gear selector is in the DRIVE position.
The transmission fluid has reached an
adequate temperature.
The engine coolant has reached an adequate
temperature.
The vehicle speed is sufficiently high.

The driver is not heavily pressing the
accelerator.

When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer,
carrying a heavy load, etc., and frequent trans -
mission shifting occurs, push the TOW/HAUL
switch to activate TOW/HAUL mode. This will
improve performance and reduce the potential
for transmission overheating or failure due to
excessive shifting. When operating in TOW/
HAUL mode, transmission upshifts are delayed,
and the transmission will automatically down -
shift (for engine braking) during steady braking
maneuvers.
The “TOW/HAUL Indicator Light” will illuminate
in the instrument cluster to indicate that TOW/
HAUL mode has been activated. Pushing the
switch a second time restores normal opera -
tion. Normal operation is always the default at
engine start-up. If TOW/HAUL mode is desired,
the switch must be pushed each time the
engine is started.

102STARTING AND OPERATING
Torque Converter Clutch
A feature designed to improve fuel economy
has been included in the automatic transmis -
sion on your vehicle. A clutch within the torque
converter engages automatically at calibrated
speeds. This may result in a slightly different
feeling or response during normal operation in
the upper gears. When the vehicle speed drops
or during some accelerations, the clutch auto -
matically disengages.
NOTE:
The torque converter clutch will not engage
until the transmission fluid and engine
coolant are warm [usually after 1 to 3 miles
(2 to 5 km) of driving]. Because the engine
speed is higher when the torque converter
clutch is not engaged, it may seem as if the
transmission is not shifting into Overdrive
when cold. This is normal. Using the Elec -
tronic Range Select (ERS) shift control, when
the transmission is sufficiently warm, will
demonstrate that the transmission is able to
shift into and out of Overdrive.
If the vehicle has not been driven for several
days, the first few seconds of operation after
shifting the transmission into gear may seem
sluggish. This is due to the fluid partially
draining from the torque converter into the
transmission. This condition is normal and
will not cause damage to the transmission.
The torque converter will refill within five
seconds after starting the engine.
POWER STEERING
The standard power steering system will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will provide mechanical steering capability if
power assist is lost.
If for some reason the power assist is inter -
rupted, it will still be possible to steer your
vehicle. Under these conditions, you will
observe a substantial increase in steering
effort, especially at very low vehicle speeds and
during parking maneuvers. NOTE:
Increased noise levels at the end of the
steering wheel travel are considered normal
and do not indicate that there is a problem
with the power steering system.
Upon initial start-up in cold weather, the
power steering pump may make noise for a
short amount of time. This is due to the cold,
thick fluid in the steering system. This noise
should be considered normal, and it does not
in any way damage the steering system.
CAUTION!
Prolonged operation of the steering system at
the end of the steering wheel travel will
increase the steering fluid temperature and it
should be avoided when possible. Damage to
the power steering pump may occur.
