Driving and Operating 187
Downshifting the transmission in
slippery road conditions could result
in skidding. See“Skidding”under
Loss of Control 0159.
The transmission can be shifted like
a manual transmission using the
paddle shift controls while in
D (Drive). See Manual Mode0187.
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 0187.
Manual Mode
Manual Paddle Shift
(Automatic Transmision)
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) 0121.
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).

188 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 0205.
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).

190 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
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
0106.
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

11374030) - 2018 - CRC - 11/8/17
192 Driving and Operating
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 while
the clutch pedal is pressed, but will
deactivate if the shift lever is left in
N (Neutral).
The system is activated and
deactivated by pressing either of the
paddles marked REV MATCH on
the steering wheel. The systemmust be activated with each new
ignition cycle. The system is
normally off.
A gear indicator in the instrument
cluster displays the current gear
selected:
.
When ARM is activated, the
gear number is amber.
. When ARM is deactivated, the
gear number is white.
. A white dash indicates that
service is required. ARM will be
disabled, and the malfunction
indicator lamp will be on. See
Malfunction Indicator Lamp
0111. The clutch and manual
transmission will continue to
operate normally. ARM will also:
.
Be active above 25 km/h
(16 mph).
. Match engine speed up to
5400 rpm.
. Not operate when the
accelerator pedal is applied.
. Be disabled when the coolant
temperature is below
0 °C (32 °F).

194 Driving and Operating
The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the ignition is
off. To prevent draining the battery,
avoid repeated cycles of the EPB
system when the engine is not
running.
The system has a
Yor PARK
Electric Parking Brake light, and a
8
Service Parking Brake light. See
Electric Parking Brake Light 0113
and Service Electric Parking Brake
Light 0114.
Before leaving the vehicle, check for
the
Yor PARK light to ensure that
the EPB is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Lift up the EPB switch momentarily.
The
Yor PARK light will flash and
then stay on once the EPB is fully
applied. If the
Yor PARK light flashes continuously, then the EPB
is only partially applied or there is a
problem with the EPB. A Driver
Information Center (DIC) message
will display. Release the EPB and
try to apply it again. If the light does
not come on, or keeps flashing,
have the vehicle serviced. Do not
drive the vehicle if the
Yor PARK
light is flashing. See your dealer.
See Electric Parking Brake Light
0 113.
If the
8light is on, press the EPB
switch and hold it. Continue to hold
the switch until the
Yor PARK
light remains on. If the
8light
remains on, see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
pressed. If the switch is pressed
until the vehicle comes to a stop,
the EPB will remain applied.
The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, block the
rear wheels to prevent vehicle
movement.
EPB Release
To release the EPB:
1. Turn the ignition on or to ACC/ ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the
Y
or PARK light is off.
If the
8light is on, release the EPB
by pressing and holding the EPB
switch. Continue to hold the switch
until the
Yor PARK light is off.
If either light stays on after release
is attempted, see your dealer.

196 Driving and Operating
Ride Control Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) and a StabiliTrak
system. These systems help limit
wheel spin and assist the driver in
maintaining control, especially on
slippery road conditions.
TCS activates if it senses that the
rear wheels are spinning too much
or are beginning to lose traction.
When this happens, TCS applies
the brakes to the spinning wheel
and reduces engine power (by
closing the throttle and managing
engine spark) to limit wheel spin.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any one of thevehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used when
TCS begins to limit wheel spin, the
cruise control will automatically
disengage. Cruise control may be
reengaged when road conditions
allow. See
Cruise Control 0205.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See If the Vehicle Is Stuck 0173
and “Turning the Systems Off and
On” later in this section.The indicator light for both systems
is in the instrument cluster. This
light will:
.
Flash when TCS is limiting
wheel spin
. Flash when StabiliTrak is
activated
. Turn on and stay on when either
system is not working
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If
dcomes on and stays on:
1. Stop the vehicle.
