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 Dis-
abled Vehicle” in “What To Do In Emergen-
cies” for further information.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest up-
shifts and downshifts, and the best fuel
economy. The transmission automatically up-
shifts through underdrive first, second, third,
and fourth gears, direct fifth gear and overdrive
sixth gear. The DRIVE position provides opti-
mum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, travel-
ing into strong head winds, or while towing
heavy trailers), use the AutoStick shift control(refer to “AutoStick (Six-Speed Automatic
Transmission)” in this section for further infor-
mation) to select a lower gear. Under these
conditions, using a lower gear will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal
operating limits, the transmission controller will
modify the transmission shift schedule and ex-
pand the range of torque converter clutch en-
gagement. This is done to prevent transmission
damage due to overheating. If the transmission
becomes extremely hot, the “Transmission
Temperature Warning Light” may illuminate and
the transmission may operate differently until
the transmission cools down.
During very cold temperatures (-4°F [-20°C] or
below), transmission operation may be modified
depending on engine and transmission tem-
perature as well as vehicle speed. Normal op-
eration will resume once the transmission tem-
perature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition isdetected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains in
fourth gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. 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
transmission 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 switch to the LOCK/OFF
position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the transmis-
sion will return to normal operation.

CAUTION!(Continued)
NEUTRAL can cause severe transmission
damage. Refer to “Recreational Towing” in
“Starting And Operating” and “Towing A Dis-
abled Vehicle” in “What To Do In Emergen-
cies” for further information.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the best fuel
economy. The DRIVE position provides opti-
mum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, travel-
ing into strong head winds, or while towing
heavy trailers), use the AutoStick shift control (if
equipped, refer to"AutoStick (CVT)"in this
section for further information) to select a lower
gear ratio. Under these conditions, using a
lower gear ratio will improve performance and
extend transmission life by reducing excessive
shifting and heat buildup.During sustained high speed driv-
ing or trailer towing up long grades
on hot days, the automatic trans-
mission oil may become too hot. If
this happens, the transmission
overheat indicator light will come on, and the
vehicle will slow slightly until the transmission
cools down enough to allow a return to the
requested speed. This is done to prevent trans-
mission damage due to overheating. If the high
speed is maintained, the overheating may reoc-
cur, as before, in a cyclic fashion.
LOW (L) — If Equipped
Use this range for engine braking when de-
scending very steep grades. In this range, the
transmission will downshift for maximum engine
braking, and upshifts will occur only to prevent
engine overspeed.
AUTOSTICK
AutoStick (Six-Speed Automatic
Transmission) — If Equipped
AutoStick is a driver-interactive transmission
feature providing manual shift control, givingyou more control of the vehicle. AutoStick al-
lows you to maximize engine braking, eliminate
undesirable upshifts and downshifts, and im-
prove overall vehicle performance. This system
can also provide you with more control during
passing, city driving, cold slippery conditions,
mountain driving, trailer towing, and many other
situations.
Operation
When the gear selector is in the DRIVE position,
the transmission will operate automatically,
shifting between the six available gears. To
engage AutoStick, simply tap the gear selector
to the right or left (+/-) while in the DRIVE
position. Tapping (-) to enter AutoStick mode will
downshift the transmission to the next lower
gear, while using (+) to enter AutoStick mode
will retain the current gear. When AutoStick is
active, the current transmission gear is dis-
played in the instrument cluster.
In AutoStick mode, the transmission will shift up
or down when the driver moves the gear selec-
tor to the right (+) or left (-), unless an engine
lugging or overspeed condition would result. It
176

will remain in the selected gear until another
upshift or downshift is chosen, except as de-
scribed below:
•The transmission will automatically upshift
when necessary to prevent engine over-
speed.
•The transmission will automatically downshift
as the vehicle slows (to prevent engine lug-
ging) 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 transmission as the vehicle is
accelerated.
•You can start out, from a stop, in first or
second gear. Tapping (+) (at a stop) will allow
starting in second gear. Starting out in sec-
ond gear can be helpful in snowy or icy
conditions.
•If a requested downshift would cause the
engine to overspeed, that shift will not occur.
•Avoid using speed control when AutoStick is
engaged.•Transmission shifting will be more noticeable
when AutoStick is engaged.
•The system may revert to automatic shift
mode if a fault or overheat condition is
detected.
To disengage AutoStick mode, hold the gear
selector to the right (+) until “D” is once again
displayed in the instrument cluster. You can shift
in or out of the AutoStick mode at any time
without taking your foot off the accelerator
pedal.
WARNING!
Do not downshift for additional engine brak-
ing on a slippery surface. The drive wheels
could lose their grip and the vehicle could
skid, causing a collision or personal injury.
AutoStick (CVT) — If EquippedAutoStick is a driver-interactive transmission
feature providing six manually selectable gear
ratios, giving you more control of the vehicle.
AutoStick allows you to maximize engine brak-
ing, eliminate undesirable upshifts and down-shifts, and improve overall vehicle performance.
This system can also provide you with more
control during passing, city driving, cold slippery
conditions, mountain driving, trailer towing, and
many other situations.
Operation
NOTE:
AutoStick is not available until the CVT
warms up in cold weather.
When the gear selector is in the DRIVE position,
AutoStick is activated by moving the gear se-
lector side-to-side. Moving the gear selector to
the right (+) will activate AutoStick and shift up
to the next higher manual ratio, unless you are
already operating in or near Overdrive, in which
case sixth gear ratio will be selected. In like
manner, moving the gear selector to the left (-)
will activate AutoStick and shift to the next lower
manual ratio. The manually-selected gear will
be displayed in the instrument cluster.
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

Brake Assist System (BAS)The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and
amount of brake application and then applies
optimum pressure to the brakes. This can help
reduce braking distances. The BAS comple-
ments the anti-lock brake system (ABS). Apply-
ing the brakes very quickly results in the best
BAS assistance. To receive the benefit of the
system, you must apply continuous braking
pressure during the stopping sequence, (do not
“pump” the brakes). Do not reduce brake pedal
pressure unless braking is no longer desired.
Once the brake pedal is released, the BAS is
deactivated.
WARNING!
The Brake Assist System (BAS) cannot pre-
vent the natural laws of physics from acting
on the vehicle, nor can it increase the trac-
tion afforded by prevailing road conditions.
(Continued)
WARNING!(Continued)
BAS cannot prevent collisions, including
those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. The capabilities of a BAS-
equipped vehicle must never be exploited in
a reckless or dangerous manner, which
could jeopardize the user’s safety or the
safety of others.
Hill Start Assist (HSA)The HSA system is designed to mitigate roll
back from a complete stop while on an incline. If
the driver releases the brake while stopped on
an incline, HSA will continue to hold the brake
pressure for a short period. If the driver does not
apply the throttle before this time expires, the
system will release brake pressure and the
vehicle will roll down the hill as normal.
The following conditions must be met in order
for HSA to activate:
•The feature must be enabled.
•The vehicle must be stopped.•Park brake must be off.
•Driver door must be closed.
•The vehicle must be on a sufficient grade.
•The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in for-
ward gear; vehicle backing uphill is in RE-
VERSE gear).
•HSA will work in REVERSE gear and all
forward gears. The system will not activate if
the transmission is in PARK or NEUTRAL.
For vehicles equipped with a manual trans-
mission, if the clutch is pressed, HSA will
remain active.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight roll-
ing may occur, such as on minor hills or with
a loaded vehicle, or while pulling a trailer.
HSA is not a substitute for active driving
involvement. It is always the driver’s respon-
sibility to be attentive to distance to other

WARNING!(Continued)
vehicles, people, and objects, and most im-
portantly brake operation to ensure safe
operation of the vehicle under all road con-
ditions. Your complete attention is always
required while driving to maintain safe con-
trol of your vehicle. Failure to follow these
warnings can result in a collision or serious
personal injury.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
WARNING!
•If you use a trailer brake controller with
your trailer, the trailer brakes may be acti-
vated and deactivated with the brake
switch. If so, there may not be enough
brake pressure to hold both the vehicle
and the trailer on a hill when the brake

WARNING!(Continued)
pedal is released. In order to avoid rolling
down an incline while resuming accelera-
tion, manually activate the trailer brake or
apply more vehicle brake pressure prior to
releasing the brake pedal.
•HSA is not a parking brake. Always apply
the parking brake fully when leaving your
vehicle. Also, be certain to leave the trans-
mission in PARK.
•Failure to follow these warnings may
cause the vehicle to roll down the incline
and could collide with another vehicle,
object or person, and cause serious or
fatal injury. Always remember to use the
parking brake while parking on a hill and
that the driver is responsible for braking
the vehicle.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:•For vehicles equipped with the Electronic
Vehicle Information Center (EVIC), refer to
