Stopping the Engine
If the vehicle has an automatic transmission, move
the shift lever to P (Park) and press and hold the
Acc. (Off/Accessory) button, located on the instrument
panel, until the engine shuts off. If the shift lever is not
in P (Park), the engine shuts off and the vehicle goes
into the Accessory Mode. The DIC displays SHIFT
TO PARK. Once the shifter is moved to P (Park),
the vehicle turns off. If the vehicle has a manual
transmission, it is recommended that you move the
shift lever to R (Reverse) and set the parking brake
after you turn off the engine by pressing and holding
the Acc. (Off/Accessory) button.
If the keyless access transmitter is not detected inside
the vehicle when it is turned to off, the DIC displays
NO FOB –OFF OR RUN?.
See DIC Warnings and Messages
on page 4‑52for
more information.
Automatic Transmission Operation
There are several
different positions for the
shift lever.
P (Park) : This position locks the rear wheels. It is the
best position to use when starting the engine because
the vehicle cannot move easily.
3-26
{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 unless you have to. 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). See Shifting Into
Park (Automatic Transmission) on page 3‑35.
Be sure the shift lever is fully in P (Park) before starting
the engine. The vehicle has an automatic transmission shift lock
control system. You have to fully apply the brakes and
then press the shift lever button before you can shift
from P (Park) when the vehicle is running. If you cannot
shift out of P (Park), ease pressure on the shift lever
and push the shift lever all the way into P (Park) as you
maintain brake application. Then press the shift lever
button and move the shift lever into another gear.
See
Shifting Out of Park on page 3‑36.
R (Reverse) : Use this gear to back up.
Notice: 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 Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on
page 5‑27.
3-27
N (Neutral) :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 Your Vehicle
on
page 5‑33.
{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.
Notice: 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 (Drive) :
This position is for normal driving. It provides
the best fuel economy. If you need more power 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 on page 5‑18.
S (Sport Mode) : When in S (Sport Mode), the
transmission will work as an automatic until you use
the Manual Paddle Shift Controls, which activates driver
manual gear selection. See Manual Paddle Shift later in
this section. While in S (Sport Mode), the transmission
will have more noticeable upshifts for sportier vehicle
performance.
3-28
When using the Manual
Paddle Shift feature while
in S (Sport Mode), the
current gear will be
displayed in the Driver
Information (DIC), or the
Head-Up Display (HUD),
if the vehicle has either of
these features.
If the vehicle has a Navigation system, see “Head-Up
Display (HUD)” in the Index of the navigation manual.
The Manual Paddle Shift system will not allow either an
up-shift or a down-shift if the vehicle speed is too fast
or too slow, nor will it allow a start from 4 (Fourth) or
higher gear
If up-shifting does not occur when needed, vehicle
speed will be limited to protect the engine.
When the transmission gear does not respond to a shift
change, the DIC will show an X over the gear display. When a requested shift is
denied due to the speed
restrictions shown, the
DIC will momentarily
show an X over the gear
display and a chime will
sound.
If the vehicle has a HUD, and the transmission gear
does not respond to a shift change, a chime will sound
and the HUD will momentarily show an X over the gear
display.
Manual Paddle Shift operation is available for use with
Cruise Control. See Cruise Control
on page 4‑7for
more information.
The vehicle speeds required for Manual Paddle Shift
up-shifts depend on several vehicle inputs, which will
vary the allowed up-shift speed by a few mph (km/h).
3-30
For vehicles with a 2.56:1 Axle Ratio
(RPO GM8)
.Up-shifts to 4 (Fourth) gear require approximately
35 km/h (22 mph).
.Up-shifts to 5 (Fifth) gear require approximately
45 km/h (28 mph).
.Up-shifts to 6 (Sixth) gear require approximately
65 km/h (41 mph).
To prevent damage to the powertrain, Manual Paddle
downshifts to a lower gear cannot be done above
certain speeds. The maximum speed allowed for
downshifting of gears 1 (First) through 4 (Fourth) are:
.Into 4 (Fourth) gear over 250 km/h (155 mph)
.Into 3 (Third) gear over 188 km/h (117 mph)
.Into 2 (Second) gear over 120 km/h (75 mph)
.Into 1 (First) gear over 68 km/h (42 mph).
For vehicles with a 2.73:1 Axle Ratio
(RPO GU2)
.Up-shifts to 4 (Fourth) gear require approximately
31 km/h (19 mph).
.Up-shifts to 5 (Fifth) gear require approximately
39 km/h (24 mph).
.Up-shifts to 6 (Sixth) gear require approximately
57 km/h (35 mph).
To prevent damage to the powertrain, Manual Paddle
downshifts to a lower gear cannot be done above
certain speeds. The maximum speed allowed for
downshifting of gears 1 (First) through 4 (Fourth) are:
.Into 4 (Fourth) gear over 234 km/h (145 mph)
.Into 3 (Third) gear over 176 km/h (109 mph)
.Into 2 (Second) gear over 113 km/h (70 mph)
.Into 1 (First) gear over 64 km/h (40 mph).
If the driver does not request an upshift as the engine
speed approaches fuel shut off RPM, the engine speed
will be limited to protect the engine. See Tachometer
on
page 4‑32for more information.
3-31
Manual Transmission Operation
This is the shift pattern
for the six-speed manual
transmission.
Here is how to operate the transmission:
1 (First) : Press the clutch pedal and shift into 1 (First).
Then slowly let up on the clutch pedal as you press the
accelerator pedal.
You can shift into 1 (First) when you are going less than
40 mph (64 km/h). If you come to a complete stop and it
is hard to shift into 1 (First), put the shift lever in Neutral
and let up on the clutch. Press the clutch pedal back
down. Then shift into 1 (First).
2 (Second) : Press the clutch pedal as you let up on the
accelerator pedal and shift into 2 (Second). Then, slowly
let up on the clutch pedal as you press the accelerator
pedal. 3 (Third), 4 (Fourth), 5 (Fifth) and 6 (Sixth) :
Shift
into 3 (Third), 4 (Fourth), 5 (Fifth) and 6 (Sixth) the same
way you do for 2 (Second). Slowly let up on the clutch
pedal as you press the accelerator pedal.
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 this position when you start or idle the
engine. The shift lever is in Neutral when it is centered
in the shift pattern, not in any gear.
R (Reverse) : To back up, press down the clutch pedal
and shift into R (Reverse). Just apply pressure to get
the lever past 5 (Fifth) and 6 (Sixth) into R (Reverse).
Let up on the clutch pedal slowly while pressing the
accelerator pedal.
The six-speed manual transmission has a feature that
allows you to safely shift into R (Reverse) while the
vehicle is rolling at less than 3 mph (5 km/h). You will be
locked out if you try to shift into R (Reverse) while the
vehicle is moving faster than 3 mph (5 km/h).
3-32
Shift Speeds (Manual Transmission)
{WARNING:
If you skip a gear when you downshift, you could
lose control of the vehicle. You could injure
yourself or others. Do not shift down more than
one gear at a time when you downshift.
This chart shows when to shift to the next higher gear
for the best fuel economy.
Manual Transmission Recommended Shift Speeds in mph (km/h)
Engine Acceleration Shift Speed
1 to 2 2 to 3 3 to 4 4 to 5 5 to 6
All
Engines 15 (24) 25 (40) 40 (64) 45 (72) 50 (80)
If the engine speed drops below 900 rpm, or if the
engine is not running smoothly, you should downshift to
the next lower gear. You may have to downshift two or
more gears to keep the engine running smoothly or for
good engine performance.
Notice:
When shifting gears, do not move the shift
lever around unnecessarily. This may damage the
transmission. Shift directly into the next gear.
One to Four Shift Light
(Manual Transmission)
When this light comes on,
you can only shift from
1 (First) to 4 (Fourth)
instead of 1 (First) to
2 (Second).
See One-to-Four Shift Light (Manual Transmission)
on
page 4‑36for more information.
3-33
Downshifting (Manual Transmission)
Do not downshift into the gear shown below at a speed
greater than shown in the table:
1 (First)50 mph (80 km/h)
2 (Second) 74 mph (119 km/h)
3 (Third) 101 mph (163 km/h)
4 (Fourth) 130 mph (209 km/h)
Notice: If you skip more than one gear when you
downshift, or if you race the engine when you
release the clutch pedal while downshifting, you
could damage the engine, clutch, driveshaft or the
transmission. Do not skip gears or race the engine
when downshifting.
The six-speed transmission has a spring that centers
the shift lever near 3 (Third) and 4 (Fourth). This
spring helps you know which gear you are in when
you are shifting. Be careful when shifting from 1 (First)
to 2 (Second) or downshifting from 6 (Sixth) to 5 (Fifth).
The spring will try to pull the shift lever toward 4 (Fourth)
and 3 (Third). Make sure you move the lever into
2 (Second) or 5 (Fifth). If you let the shift lever move
in the direction of the pulling, you may end up shifting
from 1 (First) to 4 (Fourth) or from 6 (Sixth) to 3 (Third).
Parking Brake
The parking brake lever is located to the right of the
center console.
To set the parking brake, hold the brake pedal down.
Pull the parking brake lever up. If the ignition is on, the
brake system warning light will come on.
To release the parking brake, hold the brake pedal
down. Then push the release button in as you move the
parking brake lever all the way down.
Notice: Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the
brake warning light is off before driving.
