selector. As an added precaution, always apply
the parking brake when exiting the vehicle.
COLD WEATHER OPERATION (BELOW
–22°F O
R −30°C)
To ensure reliable starting at these
temperatures, use of an externally powered
electric engine block heater (available from an
authorized dealer) is recommended.
IF ENGINE FAILS TO START
If the engine fails to start after you have
followed the "Normal Starting" or "Cold Weather
Operation" procedure, and has not experienced
an extended park condition as identified in
"Extended Park Starting" procedure it may be
flooded. Push the accelerator pedal all the way
to the floor and hold it there. Crank the engine
for no more than 15 seconds. This should clear
any excess fuel in case the engine is flooded.
Leave the ignition key in the RUN position,
release the accelerator pedal and repeat the
“Normal Starting” procedure.
AFTER STARTING
The idle speed is controlled automatically, and
it will decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and
permits quicker starts in cold weather. Connect
the cord to a standard 110-115 Volt AC
electrical outlet with a grounded, three-wire
extension cord.
The engine block heater must be plugged in at
least one hour to have an adequate warming
effect on the engine.
The engine block heater cord is routed under
the hood on the driver side of the vehicle. It has
a removable cap that is located near the air box.
WARNING!

Never pour fuel or other flammable liquid
into the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.

Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine has
started, ignite and damage the converter
and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a
start from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly. Refer to
“Jump Starting Procedure” in “In Case Of
Emergency” for further information.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds
before trying again.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.

When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill
grade and away from the curb on an uphill
grade. Apply the parking brake before placing
the gear selector in PARK, otherwise the load on
the transmission locking mechanism may make
it difficult to move the gear selector out of PARK.
The parking brake should always be applied
whenever the driver is not in the vehicle.

IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to be
in PARK before the ignition can be turned to the
OFF mode. This helps the driver avoid
inadvertently leaving the vehicle without placing
the transmission in PARK. This system also
locks the transmission in PARK whenever the
ignition is in the OFF mode.
NOTE:
The transmission is NOT locked in PARK when
the ignition is in the ACC mode (even though the
engine will be off). Ensure that the transmission
is in PARK, and the ignition is OFF (not in ACC
mode) before exiting the vehicle.
BRAKE/TRANSMISSION SHIFT
I
NTERLOCK SYSTEM
This vehicle is equipped with a Brake
Transmission 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 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.
EIGHT-SPEED AUTOMATIC
T
RANSMISSION
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.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting the vehicle.
The transmission may not engage PARK if
the vehicle is moving. Always bring the
vehicle to a complete stop before shifting to
PARK, and verify that the transmission gear
position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is
completely stopped, and the PARK position
is properly indicated, 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, and turn the igni -
tion OFF. When the ignition is in the OFF
mode, the transmission is locked in PARK,
securing the vehicle against unwanted
movement.
When exiting the vehicle, always make sure
the ignition is in the OFF mode, remove the
key fob from the vehicle, and lock the
vehicle.

STARTING AND OPERATING157
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 characteristics
under 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
(if equipped, refer to “AutoStick” in this section
for further information) 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.
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.
SPORT (S) — If Equipped
This mode alters the transmission's automatic
shift schedule for sportier driving. Upshift
speeds are increased to make full use of
available engine power.
To access SPORT mode, push down on the gear
selector and rotate it fully clockwise, or push the
SPORT button in the center stack.
LOW (L) — If Equipped
Use this range for engine braking when
descending very steep grades. In this range, the
transmission will downshift for increased
engine braking. To access the LOW position,
push down on the gear selector and rotate it
fully clockwise.
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 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).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.

158STARTING AND OPERATING

1. Stop the vehicle.

2. Shift the transmission into PARK, if
possible. If not, shift the transmission to
NEUTRAL.
3. Push and hold the ignition switch 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.

NOTE:
Even if the transmission can be reset, we
recommend that you visit an authorized dealer
at your earliest possible convenience. An autho -
rized dealer has diagnostic equipment to
assess the condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.
AutoStick — If Equipped
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 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 transmission is in DRIVE or SPORT
mode, it will operate automatically, shifting
between the eight available gears. To engage
AutoStick, simply tap one of the steering
wheel-mounted shift paddles (+/-) while in
DRIVE or SPORT mode. In DRIVE mode, this will
activate a temporary AutoStick mode. The
transmission will revert back to normal
operation after a period of time, depending on
accelerator pedal activity. When the
transmission gear selector is in the SPORT
position, tapping either shift paddle will activate
"permanent" AutoStick mode. The transmission
will remain in AutoStick mode until the driver
deliberately disables AutoStick (as described
below). Tapping (-) to enter AutoStick will
downshift the transmission to the next lower
gear, while using (+) to enter AutoStick will
retain the current gear. When AutoStick is active, the current transmission gear is
displayed in the instrument cluster.

Paddle Shifters

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.
If AutoStick is engaged while in DRIVE mode,
the transmission will automatically shift up
when maximum engine speed is reached. If
the accelerator is fully depressed, the trans -
mission will downshift when possible (based
1 — Shift Paddle Downshift
2 — Shift Paddle Upshift

20_LX_OM_EN_USC_t.book Page 158

STARTING AND OPERATING159
on current vehicle speed and gear). Lack of
accelerator pedal activity will cause the
transmission to revert to automatic opera -
tion.
If AutoStick is engaged while the transmis -
sion gear selector is in the SPORT position,
manual gear selection will be maintained
until the gear selector is returned to DRIVE, or
as described below. The transmission will not
upshift automatically at redline in this mode,
nor will downshifts be obtained if the acceler -
ator pedal is pressed to the floor.
In either DRIVE or SPORT mode, the transmis -
sion will automatically downshift as the
vehicle slows (to prevent engine lugging) and
will display the current gear.
The transmission will automatically down -
shift 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
SECOND gear can be helpful in snowy or icy
conditions.
If a requested downshift would cause the
engine to over-speed, that shift will not occur.
The system will ignore attempts to upshift at
too low of a vehicle speed.
Holding the (-) paddle depressed will down -
shift 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.
To disengage AutoStick mode, press and hold
the (+) shift paddle until "D" or "S" is once again
indicated in the instrument cluster. Shifting out
of SPORT mode will also disable AutoStick. You
can shift in or out of AutoStick mode at any time
without taking your foot off the accelerator
pedal.
SPORT MODE — IF EQUIPPED

SPORT Mode Button

If your vehicle is equipped with SPORT mode,
this mode is a configuration set up for typical
enthusiast driving. The engine, transmission
and steering systems are all set to their SPORT
settings. SPORT Mode will provide improved
throttle response and modified shifting for an
enhanced driving experience, as well the
greatest amount of steering feel. This mode
may be activated and deactivated by pushing
the SPORT button on the instrument panel
switch bank.
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.
