BRAKE/TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI system that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the engine must be
running and the brake pedal must be pressed. The
brake pedal must also be pressed to shift from
NEUTRAL into DRIVE or REVERSE when the vehicle
is stopped or moving at low speeds.
8–SPEED AUTOMATIC TRANSMISSION
The transmission gear range (PRNDM) is displayed
both beside the gear selector and in the
instrument cluster. To select a gear range, push
the lock button on the gear selector and move the
selector rearward or forward. To shift the
transmission out of PARK, the engine must be
running and the brake pedal must be pressed. You
must also press the brake pedal to shift from
NEUTRAL into DRIVE or REVERSE when the vehicle
is stopped or moving at low speeds. Select the
DRIVE range for normal driving.
NOTE:In the event of a mismatch between the gear
selector position and the actual transmission gear
(for example, driver selects PARK while driving),
the position indicator will blink continuously until
the selector is returned to the proper position, or
the requested shift can be completed.
The electronically controlled transmission adapts
its shift schedule based on driver inputs, along
with environmental and road conditions. The
transmission 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).
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 MANUAL
(AutoStick) shift positions. Manual shifts can be
made using the AutoStick shift control. Toggling
the gear selector forward (-) or rearward (+) while
in the MANUAL (AutoStick) position (beside the
DRIVE position) will manually select the
transmission gear, and will display the current gear
in the instrument cluster Ú page 160.
Gear Selector

NOTE:If the gear selector cannot be moved to the PARK,
REVERSE, or NEUTRAL position (when pushed
forward), it is probably in the AutoStick (+/-)
position (beside the DRIVE position). In AutoStick
mode, the transmission gear (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 press the accelerator pedal when shifting
out of PARK or NEUTRAL.
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before acceler
-
ating. This is especially important when the engine
is cold.

23_JT_OM_EN_USC_t.book Page 157

STARTING AND OPERATING159
The following indicators should be used to ensure
that you have properly engaged the transmission
into the PARK position:
When shifting into PARK, push the lock button
on the gear selector and firmly move the gear
selector all the way forward until it stops and is
fully seated.
Look at the transmission gear position display
and verify that it indicates the PARK position (P),
and is not blinking.
With the brake pedal released, verify that the
gear selector will not move out of PARK.
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. 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 should be used
for all normal operating conditions.When frequent transmission shifting occurs (such
as when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong
head winds, or while towing a heavy trailer), use
the AutoStick shift control to select a lower gear
Ú
page 160. Under these conditions, using a lower
gear will improve performance and extend
transmission life by reducing excessive shifting
and heat build-up.
During extremely cold temperatures (-22°F
[-30°C] or below), transmission operation may be
modified depending on engine and transmission
temperature as well as vehicle speed. Normal
operation will resume once the transmission
temperature has risen to a suitable level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of
transmission shifting also known as AutoStick
mode. Toggling the gear selector forward (-) or
rearward (+) while in the MANUAL (AutoStick)
position will manually select the transmission gear,
and will display the current gear in the instrument
cluster Ú page 160.
Transmission Limp Home Mode
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home mode is activated. In this
CAUTION!
Before moving the transmission gear selector
out of PARK, you must start the engine, 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.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.

For Recreational Towing Ú page 205.
For Towing A Disabled Vehicle Ú page 350.

160STARTING AND OPERATING
mode, the transmission may operate only in
certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the
engine may stall. In some situations, the
transmission may not re-engage if the engine is
turned off and restarted. The Malfunction Indicator
Light (MIL) may be illuminated. A message in the
instrument cluster will inform the driver of the
more serious conditions, and indicate what actions
may be necessary.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
NOTE:
In cases where the instrument cluster message
indicates the transmission may not re-engage
after engine shutdown, perform this procedure
only in a desired location (preferably, at an
authorized dealer).
Even if the transmission can be reset, we recom -
mend that you visit an authorized dealer at your
earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.

1. Stop the vehicle.

2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL. 3. Push and hold the ENGINE START/STOP
button until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the
transmission will return to normal operation.
AutoStick
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to
maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall
vehicle performance. This feature can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing, and many other situations.
Operation
To activate AutoStick mode, move the gear
selector into the MANUAL (M) position (beside the
DRIVE position). The current transmission gear will
be displayed in the instrument cluster. In AutoStick
mode, you can use the gear selector (in the
MANUAL position) to manually shift the
transmission. Tapping the gear selector forward (-)
while in the MANUAL (M) position will downshift the
transmission to the next lower gear. Tapping the
selector rearward (+) will command an upshift. In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
unless an engine lugging or overspeed condition
would result. It will remain in the selected gear
until another upshift or downshift is chosen, except
as described below:
The transmission will automatically downshift
as the vehicle slows (to prevent engine lugging)
and will display the current gear.
The transmission will automatically downshift to
FIRST gear when coming to a stop. After a stop,
the driver should manually upshift (+) the trans
-
mission as the vehicle is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear (or THIRD gear, in 4L range).
Tapping (+) (at a stop) will allow starting in
SECOND gear. Starting out in SECOND or THIRD
gear can be helpful in snowy or icy conditions.
If a requested downshift would cause the
engine to overspeed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed.
Holding the gear selector in the (-) position will
downshift the transmission to the lowest gear
possible at the current speed.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected.

ELECTRO-HYDRAULIC POWER STEERING
Your vehicle is equipped with an Electro-Hydraulic
Power Steering system that will provide increased
vehicle response and ease of maneuverability. If
the Electro-Hydraulic Power Steering system
experiences a fault that prevents it from providing
power steering assist, then the system will provide
mechanical steering capability.

23_JT_OM_EN_USC_t.book Page 168

STARTING AND OPERATING169
If the “SERVICE POWER STEERING”
message and a flashing icon are
displayed on the instrument cluster
screen, it indicates that the vehicle
needs to be taken to an authorized dealer for
service. It is likely the vehicle has lost power
steering assistance Ú page 121.
If the “POWER STEERING HOT” message and an
icon are displayed on the instrument cluster
screen, it indicates that extreme steering
maneuvers may have occurred, which caused an
over temperature condition in the power steering
system. You will lose power steering assistance
momentarily until the over temperature condition
no longer exists. Once driving conditions are safe,
pull over and let vehicle idle for a few moments
until the light turns off Ú page 121.
NOTE:
Even if power steering assistance is no longer
operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -cially at very low vehicle speeds and during
parking maneuvers.
If the condition persists, see an authorized
dealer for service.
