9-32 Driving and Operating
{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 shut
off rpm, the engine speed will be
limited to protect the engine. See
Tachometer on page 5-11.
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.
The system is activated and
deactivated by pressing either of the
paddles marked REV MATCH on
the steering wheel. The system
must be activated with each new
ignition cycle.

Driving and Operating 9-33
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 on
page 5-15. The clutch and
manual transmission will
continue to operate normally.
ARM will also:
.Be active above 32 km/h
(20 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).
Brakes
Antilock Brake
System (ABS)
This vehicle has ABS, an advanced
electronic braking system that helps
prevent a braking skid.
When the vehicle begins to drive
away, ABS checks itself.
A momentary motor or clicking noise
might be heard while this test is
going on, and it might even be
noticed that the brake pedal moves
a little. This is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
on page 5-19. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses the wheels are
slowing down. If one of the wheels
is about to stop rolling, the computer
will separately work the brakes at
each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle

6007198) - 2014 - CRC - 2/5/14
Driving and Operating 9-35
The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake status light flashes
continuously, then the EPB is only
partially applied or there is a
problem with the EPB. A 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 red
parking brake status light is flashing.
See your dealer. SeeElectric
Parking Brake Light on page 5-18.
If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light 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
held up. If the switch is held up 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, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB:
1. Place the ignition in the ACC/
ACCESSORY or ON/RUN
position.
2. Apply and hold the brake pedal.
3. Push down momentarily on the EPB switch.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by
pushing down on the EPB switch
and holding it down. Continue to
hold the switch until the red parking brake status light is off. If either light
stays on after release is attempted,
see your dealer.
{Caution
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.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
The EPB can also be used to
prevent roll back for vehicles with a
manual transmission taking off on a
hill. When no roll back is desired, an
applied EPB will allow both feet to
be used for the clutch and

accelerator pedals in preparation for
starting the vehicle moving in the
intended direction. In this case,
there is no need to push the switch
to release the EPB.
Brake Assist
The Brake Assist feature is
designed to assist the driver in
stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time isnormal and the driver should
continue to apply the brake pedal as
the driving situation dictates. The
Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
If equipped, HSA may automatically
activate when the vehicle is stopped
on a grade. This feature is designed
to prevent the vehicle from rolling,
either forward or rearward, during
vehicle drive off. During the
transition from releasing the brake
pedal to accelerating to drive off on
a grade, HSA holds the braking
pressure to prevent rolling. HSA will
not activate if the vehicle is in a
drive gear and facing downhill or if
the vehicle is facing uphill and in
R (Reverse).
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.

6007198) - 2014 - CRC - 2/5/14
Driving and Operating 9-37
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 the
vehicle 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. SeeCruise Control on
page 9-47.
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 on
page 9-13 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.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on
and stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.

Competitive Driving Mode
If equipped, Competitive Driving
Mode, Performance Traction
Management, and Launch Control
are systems designed to allow
increased performance while
accelerating and/or cornering. This
is accomplished by regulating and
optimizing the engine, brakes, and suspension performance. These
modes are for use at a closed
course race track and are not
intended for use on public roads.
They will not compensate for driver
inexperience or lack of familiarity
with the race track. Drivers who
prefer to allow the system to have
more control of the engine, brake,
and suspension are advised to turn
the normal traction control and
StabiliTrak systems on.
{Caution
Attempting to shift when the drive
wheels are spinning and do not
have traction may cause damage
to the transmission. Damage
caused by misuse of the vehicle
is not covered by the vehicle
warranty. Do not attempt to shift
when the drive wheels do not
have traction.
Competitive Driving Mode
(Except Z51 with Magnetic
Selective Ride Control)
Competitive Driving Mode allows full
engine power while StabiliTrak
helps maintain directional control of
the vehicle by selective brake
application. In this mode, TCS is off
and Launch Control is available.
Adjust your driving style to account
for the available engine power. See
“Launch Control”

Launch Control (Track
Mode Only)
A Launch Control feature is
available, within Competitive Driving
Mode (except Z51 with Magnetic
Selective Ride Control) or Performance Traction Management
(Z51 with Magnetic Selective Ride
Control), on all vehicles to allow the
driver to achieve high levels of
vehicle acceleration in a straight
line. Launch Control is a form of
traction control that manages tire
spin while launching the vehicle.
This feature is intended for use
during closed course race events
where consistent zero to
60 and quarter mile times are
desirable.
Launch Control is only available
when the following criteria are met:
.Competitive Driving Mode is
selected (except Z51 with
Magnetic Selective Ride Control)
or any of the Performance
Traction Management modes
are selected (Z51 with Magnetic
Selective Ride Control). The
TCS light comes on the
instrument panel and the
appropriate DIC message
displays.
.The vehicle is not moving.
.The steering wheel is pointing
straight.
Manual Transmissions
.The clutch is pressed and the
vehicle is in 1 (First) gear.
.The accelerator pedal is rapidly
applied to wide open throttle.
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow
the engine rpm to stabilize.
A smooth, quick release of the
clutch, while maintaining the fully
pressed accelerator pedal, will
manage wheel slip. Complete shifts
