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 P (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 transmission
parking pawl, so you can pull the
shift lever out of P (Park).
Shifting out of Park
Shift lock release prevents shifting
out of P (Park) unless the vehicle is
running or in accessory mode and
the brake pedal is applied.
The shift lock release is always
functional except in the case of an
uncharged or low voltage (less than
9-volt) battery. See Jump Starting -
North America 0292.
To shift out of P (Park): 1. Apply the brake pedal.
2. Release the parking brake. See Electric Parking
Brake 0197.
3. Press the shift lever button.
4. Move the shift lever to the desired position.
If you still are unable to shift out of
P (Park):
1. Fully release the shift lever button, and let go of the
shift knob.
2. While holding down the brake pedal, 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.
Parking (Manual
Transmission)
Before exiting the vehicle, move the
shift lever into 1 (First) or
R (Reverse), and apply the parking
brake. Once the shift lever has been
placed into 1 (First) or R (Reverse)
with the clutch pedal pressed in,
turn the ignition off and release the
clutch.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.

188 Driving and Operating
Active Fuel Management®
This system allows the engine to
operate on either all or half of its
cylinders, depending on the driving
conditions. With a manual
transmission, the system is only
active in Eco mode. With an
automatic transmission, the system
is available in all modes, but is more
aggressive in Eco mode. SeeDriver
Mode Control 0201.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the
vehicle to achieve better fuel
economy. When greater power
demands are required, such as
accelerating from a stop, passing,
or merging onto a freeway, the
system will maintain full-cylinder
operation.
Extended Parking
It is better not to park with the
vehicle running. If the vehicle is left
while running, follow the proper
steps to be sure the vehicle will not
move and there is adequate
ventilation. See Shifting Into Park
0 186 andEngine Exhaust 0188.
If the vehicle is left in P (Park) while
running and the Remote Keyless
Entry (RKE) transmitter is outside
the vehicle, the vehicle will turn off
after one hour.
If the vehicle is left in P (Park) while
running and the RKE transmitter is
inside, the vehicle will run for two
hours. At the end of the second
hour, the vehicle will turn off.
The timer will reset if the vehicle is
taken out of P (Park) while it is
running.
Engine Exhaust
{Warning
Engine exhaust contains carbon
monoxide (CO), which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if: . The vehicle idles in areas
with poor ventilation
(parking garages, tunnels,
deep snow that may block
underbody airflow or tail
pipes).
. The exhaust smells or
sounds strange or different.
. The exhaust system leaks
due to corrosion or damage.
. The vehicle exhaust system
has been modified,
damaged, or improperly
repaired.

Warning (Continued)
.There are holes or openings
in the vehicle body from
damage or aftermarket
modifications that are not
completely sealed.
If unusual fumes are detected or
if it is suspected that exhaust is
coming into the vehicle: . Drive it only with the
windows completely down.
. Have the vehicle repaired
immediately.
Never park the vehicle with the
engine running in an enclosed
area such as a garage or a
building that has no fresh air
ventilation.
Running the Vehicle
While Parked
It is better not to park with the
engine running.
If the vehicle is left with the engine
running, follow the proper steps to
be sure the vehicle will not move.
See Shifting Into Park 0186 and
Engine Exhaust 0188. If the vehicle
has a manual transmission, see
Parking (Manual
Transmission) 0187.
Automatic
Transmission
There are several different positions
for the shift lever.
P : This position locks the rear
wheels. It is the best position to use
when starting the engine because
the vehicle cannot move easily.

190 Driving and Operating
{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
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).
SeeShifting Into Park 0186.
Be sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. Fully apply the brakes and
then press the shift lever button
before shifting from P (Park) when
the vehicle is running. If the vehicle
cannot be shifted out of P (Park),
ease pressure on the shift lever and
push the shift lever all the way into P (Park) as brake application is
maintained. Then press the shift
lever button and move the shift lever
into another gear. See
Shifting out
of Park 0187.
R : Use this gear to back up.
Caution
Shifting to R (Reverse) while the
vehicle is moving forward could
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Shift to
R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to
get out of snow, ice, or sand without
damaging the transmission, see If
the Vehicle Is Stuck 0177.
N : In this position, the engine does
not connect with the wheels. To
restart the engine when the vehicle
is already moving, use N (Neutral)
only. If the vehicle needs towing,
see Towing the Vehicle 0295.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Caution
Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
D : This position is for normal
driving. It provides the best fuel
economy. If more power is needed

for passing, push the pedal down to
achieve the desired level of
acceleration.
Downshifting the transmission in
slippery road conditions could result
in skidding. See“Skidding”under
Loss of Control 0164.
The transmission can be shifted like
a manual transmission using the
paddle shift controls while in
D (Drive). See Manual Mode0191.
M : In M (Manual Mode), the
transmission can be shifted like a
manual transmission using the
paddle shift controls. See Manual
Mode 0191.Manual Mode
Manual Paddle Shift
When the shift lever is moved to
M (Manual Mode), the transmission
enters Manual Mode. The
transmission will hold the current
gear until a change is requested.
The paddles on the steering wheel
can be used to manually upshift or
downshift the transmission. The
right (+) plus paddle upshifts, and
the left (−) minus paddle downshifts.
When using the Manual Paddle
Shift feature while in M (Manual
Mode), the current gear will be
displayed in the instrument cluster,
or the Head-Up Display (HUD),
if equipped. See Head-Up Display
(HUD) 0117.
When accelerating the vehicle from
a stop in snowy and icy conditions,
shifting to 2 (Second) gear allows
the vehicle to gain more traction.
The Manual Paddle Shift system
can be deactivated by moving the
shift lever from M (Manual Mode)
back to D (Drive).

192 Driving and Operating
When the shift lever is in D (Drive),
press either the right (+) plus paddle
or the left (−) minus paddle to place
the transmission in Temporary
Manual Paddle Shift mode. The
gear indicator by the shift lever, in
the cluster, and in the HUD will
display an M, even though the shift
lever is still in D (Drive). To exit the
system, hold the (+) plus paddle for
more than one second. The system
will return to automatic shifting after
six seconds of cruising at a steady
speed, no manual shifts, no
aggressive cornering, or when the
vehicle comes to a stop.
While the Manual Paddle Shift gear
selection system is active, the
transmission will automatically
downshift through the gears as the
vehicle slows. The transmission willselect 1 (First) gear as the vehicle
stops. From a stop, the vehicle will
start from and hold 1 (First) gear
unless the manual paddle shifts are
used to shift into a different gear,
or D (Drive) is selected.
If the left (−) minus paddle is held
down briefly, the transmission will
downshift to the lowest gear
possible for the vehicle speed. If the
paddle continues to be held as the
vehicle slows, downshifts will
continue to occur as vehicle speed
allows. This feature also works
while in Temporary Manual Paddle
Shift mode, but first press and
release the (−) minus paddle to
enter Temporary Manual Paddle
Shift mode, then press and hold the
(−) minus paddle briefly.
The Manual Paddle Shift system will
not allow an upshift or a downshift if
the vehicle speed is too fast or too
slow, nor will it allow a start from
3 (Third) or higher gear.
If upshifting does not occur when
needed, vehicle speed will be
limited to protect the engine.
When a requested shift is denied
due to the speed restrictions shown,
a DIC message will be displayed,
and the current gear remains
displayed in the cluster and HUD.
Manual Paddle Shift operation is
available for use with cruise control.
See
Cruise Control 0209.
The vehicle speeds required for
Manual Paddle Shift upshifts
depend on several vehicle inputs,
which will vary the allowed upshift
speed by a few km/h (mph).
For Vehicles with a 2.41:1 Axle
Ratio (RPO GXB)
. Upshifts to 3 (Third) gear require
approximately 25 km/h (16 mph).
. Upshifts to 4 (Fourth) gear
require approximately 37 km/h
(23 mph).
. Upshifts to 5 (Fifth) gear require
approximately 48 km/h (30 mph).
. Upshifts to 6 (Sixth) gear require
approximately 60 km/h (37 mph).
. Upshifts to 7 (Seventh) gear
require approximately 74 km/h
(46 mph).

194 Driving and Operating
Manual Transmission
To operate:
1 :Press the clutch pedal and shift
into 1 (First). Then slowly let up on
the clutch pedal as the accelerator
pedal is pressed.
This can be done if the vehicle is
going less than 64 km/h (40 mph).
If the vehicle is at a complete stop
and it is hard to shift into 1 (First),
put the shift lever in Neutral and let
up on the clutch. Then press the
clutch pedal back down and shift
into 1 (First). 2 :
Press the clutch pedal while
letting up on the accelerator pedal
and shift into 2 (Second). Then,
slowly let up on the clutch pedal as
the accelerator pedal is pressed.
3, 4, 5, 6, and 7 : Shift into
3 (Third), 4 (Fourth), 5 (Fifth),
6 (Sixth), and 7 (Seventh) the same
way as for 2 (Second).
To stop, let up on the accelerator
pedal and press the brake pedal.
Just before the vehicle stops, press
the clutch pedal and the brake
pedal, and shift to Neutral.
Neutral : Use to start or idle the
engine. Neutral is the center
position of the shift pattern.
R : To back up, push the clutch
pedal and shift into R (Reverse).
Additional pressure may be needed
to move the lever past 5 (Fifth) and
6 (Sixth) into R (Reverse). Let up on
the clutch pedal slowly while
pressing the accelerator pedal. The vehicle can be safely shifted
into R (Reverse) while the vehicle is
moving less than 5 km/h (3 mph).
If the vehicle is going faster than
that, R (Reverse) is locked out.
Shift Speeds
Use the following shift speeds,
shown in km/h (mph), for the best
fuel economy.
1 to 4 27 (17)
4 to 5 40 (25)
5 to 6 64 (40)
6 to 7 72 (45)
Caution
When shifting gears, do not move
the shift lever around
unnecessarily. This may damage
the transmission. Shift directly
into the next gear.

1–4 Shift Message
When the DIC displays this
message, the vehicle can only be
shifted from 1 (First) to 4 (Fourth).
SeeTransmission Messages 0131.
Downshifting
Do not downshift into the gear at a
speed greater than shown:
1 (First) 72 km/h (45 mph)
2 (Second) 107 km/h (67 mph)
3 (Third) 160 km/h (100 mph)
4 (Fourth) 233 km/h (145 mph)
Caution
When downshifting, if more than
one gear is skipped, or the engine
is racing when the clutch pedal is
released, the engine, clutch,
driveshaft or transmission could
be damaged. If the engine speed drops below
900 rpm, or if the engine is not
running smoothly, downshift to the
next lower gear. It may be
necessary to downshift two or more
gears.
The transmission has a spring that
centers the shift lever near 3 (Third)
and 4 (Fourth). This spring helps to
know what gear the shift lever is in
when shifting. Be careful when
shifting from 1 (First) to 2 (Second)
or downshifting from 7 (Seventh) to
6 (Sixth). The spring will try to pull
the shift lever toward 4 (Fourth) and
3 (Third). Move the lever into
2 (Second) or 6 (Sixth) and do not
let the shift lever move in the
direction of the pulling, or it could
shift from 1 (First) to 4 (Fourth) or
from 7 (Seventh) to 4 (Fourth).
If the vehicle is not upshifted as the
engine speed approaches fuel
shutoff rpm, the engine speed will
be limited to protect the engine. See
Tachometer
0103.
Active Rev Match
Vehicles equipped with a manual
transmission have Active Rev Match
(ARM). ARM aids in smoother
shifting by matching the engine
speed to the next selected gear. By
monitoring shift lever and clutch
operation, ARM adjusts engine
speed to match a calibrated value
based on gear selection. On
upshifts and downshifts, engine
speed will be increased and
decreased to match vehicle road
speed and transmission gear
position. ARM is maintained for a
few seconds between shifts, then
deactivates if the shift is not
completed.
