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 best not to park with the vehicle
running. If the vehicle is left running,
be sure it will not move and there is
adequate ventilation.
SeeShifting Into Park 0184 and
Engine Exhaust 0186.
If the vehicle is left parked and
running with the Remote Keyless
Entry (RKE) transmitter outside the
vehicle, it will continue to run for up
to half an hour. If the vehicle is left parked and
running with the RKE transmitter
inside the vehicle, it will continue to
run for up to an hour.
The vehicle could turn off sooner if it
is parked on a hill, due to lack of
available fuel.
Automatic Transmission
The timer will reset if the vehicle is
taken out of P (Park) while it is
running.
Manual Transmission
The timer will reset if vehicle speed
exceeds 4 km/h (2.5 mph).
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.

188 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 0184.
Be sure the shift lever is 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 0185.
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 0175.
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.
{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. If more power is needed for
passing, press the accelerator
pedal down.

Driving and Operating 189
Downshifting the transmission in
slippery road conditions could result
in skidding. See“Skidding”under
Loss of Control 0161.
The transmission can be shifted like
a manual transmission using the
paddle shift controls while in
D (Drive). See Manual Mode0189.
Caution
A transmission hot message may
display if the automatic
transmission fluid is too hot.
Driving under this condition can
damage the vehicle. Stop and idle
the engine to cool the automatic
transmission fluid. This message
clears when the transmission fluid
has cooled sufficiently.
M : In M (Manual Mode), the
transmission can be shifted like a
manual transmission using the
paddle shift controls. See Manual
Mode 0189.
Manual Mode
Manual Paddle Shift
(Automatic Transmission)
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) 0123.
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).

190 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 next to 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 thevehicle slows. The transmission will
select 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 instrument cluster
and HUD.
Manual Paddle Shift operation is
available for use with cruise control.
See
Cruise Control 0207.
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).

192 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.
Caution
A transmission hot message may
display if the manual transmission
fluid is too hot. Driving at high
speed under this condition can
damage the vehicle. Drive at a
slower speed, or stop and idle the
engine to cool the manual
transmission fluid. The message
clears when the vehicle has
slowed and the transmission fluid
has cooled sufficiently.

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
(LT5 and ZR1)
When the DIC displays this
message, the vehicle can only be
shifted from 1 (First) to 4 (Fourth).
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
0108.
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
