224 Driving and Operating
When this message comes on, the
vehicle can only be shifted from
1 (First) to 4 (Fourth) instead of
1 (First) to 2 (Second). The message
will display in the Driver Information
Center (DIC).
Complete the shift into 4 (Fourth) to
turn off this feature. This helps to
get the best possible fuel economy.
After shifting to 4 (Fourth), downshift
to a lower gear, if desired.
Caution
Forcing the shift lever into any
gear except 4 (Fourth) when the
1-4 SHIFT message comes on
may damage the transmission.
Shift only from 1 (First) to
4 (Fourth) when the message
comes on.
This message will come on when:
. The engine coolant temperature
is higher than 76 °C (169 °F).
. The vehicle is accelerating from
a stop and going 24 to 31 km/h
(15 to 19 mph). .
The vehicle is at 33% throttle
or less.
Vehicles equipped with a Head-Up
Display (HUD) may also have shift
timing lights across the top of the
display.
The rows of lights get closer
together as the shift point gets
closer. Shift the transmission before
the lights come together in the
display. Shift immediately if the
lights are flashing.
See Head-Up Display (HUD) 0132.Active Rev Match
Vehicles equipped with a V8 engine
and 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 decreased and
increased 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
the Neutral position.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.
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.

Driving and Operating 225
.If no gear number is displayed
while the shift lever is in gear,
service is required. ARM will be
disabled, and the malfunction
indicator lamp will be on. See
Malfunction Indicator Lamp
0123. 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).Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock Brake
System (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
may be heard while this test is going
on, and it may 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
0 126. 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
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.

226 Driving and Operating
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You may hear the ABS
pump or motor operating and feel
the brake pedal pulsate. This is
normal.
Braking in Emergencies
ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Electric Parking Brake
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
0 125 andService Electric Parking
Brake Light 0126.
Before leaving the vehicle, check for
the
Yor PARK light to ensure that
the parking brake 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 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 0125.
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.

Driving and Operating 227
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.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
(Continued)
Caution (Continued)
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 press the switch
to release the EPB.
Brake Assist
This vehicle has a brake assist
feature 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 is
normal 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.

228 Driving and Operating
Hill Start Assist (HSA)
If equipped, Hill Start Assist (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
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak, an
electronic stability control system.
These systems help limit wheel slip
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that any
of the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to
the spinning wheels and reduces
engine power 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 and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
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 0205
and “Turning the Systems Off and
On” later in this section.

Driving and Operating 229
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.

Engine Drag Control (EDC)
EDC improves vehicle stability by
sensing if there is a difference in
speed between the free rolling front
wheels and the rear drive wheels
that often occurs when the driver
takes their foot off the accelerator
pedal on slippery surfaces (snow,
ice, etc.). When this is detected,
EDC sends more torque to the rear
wheels to make sure all four wheels
are spinning at similar speeds,
making the vehicle more stable.
Driver Mode Control
Driver Mode Control attempts to add
a sportier feel, provide a more
comfortable ride, or assist in
different weather conditions or
terrain. This system simultaneously changes the software calibration of
various sub-systems. Depending on
the option package, available
features, and mode selected, the
suspension, steering, and
powertrain will change calibrations
to achieve the desired mode
characteristics. If the vehicle is
equipped with Magnetic Ride
Control, selecting the various Driver
Modes adjusts the ride of the
vehicle to enhance the ride
performance for the road conditions
and the selected mode.
While in the Sport and/or Track
Modes, the vehicle monitors driving
behavior and automatically enables
Performance Shift Features when
spirited driving is detected. These
features maintain lower
transmission gears to increase
available engine braking and
improve acceleration response. The
vehicle will exit these features and
return to normal operation after a
short period when no spirited driving
is detected.
Driver Mode Control Switch
The Driver Mode Control has three
or four modes: Tour, Sport, Snow/
Ice, and Track. Press
«orzon
the MODE switch on the center
console to make a mode selection.
Pressing the switch will display a
graphic of all available ride modes
and change to the next mode. The
Tour and Sport Modes will feel
similar on a smooth road. Select a
new setting whenever driving
conditions change.

When selected, the Tour Mode
indicator will display in the Driver
Information Center (DIC).
Sport Mode
Use where road conditions or
personal preference demand a more
controlled response.
When selected, the Sport Mode
indicator will display in the DIC.
When in Sport Mode, the vehicle will
shift automatically but hold a lower
gear longer than it would in the
normal driving mode based on
braking, throttle input, and vehicle
lateral acceleration. SeeAutomatic
Transmission 0218. The steering
will change to provide more precise
control. If the vehicle has Magnetic

change to provide better cornering
performance. If the vehicle is
equipped with Active Exhaust, the
exhaust valves will open earlier and
more often. Competitive Driving Mode can be accessed through this
mode by pressing the button with
this
gicon twice.
Snow/Ice Mode
Use when more traction is needed
during slippery conditions. The
vehicle will upshift normally when
the vehicle is moving. The
acceleration will adjust to help
provide a smoother launch. The
transmission will also shift differently
to assist in maintaining traction.
When selected, the Snow/Ice Mode
indicator will display in the DIC.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
vehicle becomes stuck, see
If the
Vehicle Is Stuck 0205.
Track Mode
Use when maximum vehicle
handling is desired.
When selected, the Track Mode
indicator will display in the DIC. When in Track Mode, the automatic
transmission and steering will
function similar to Sport Mode. The
accelerator pedal is adjusted to give
maximum control during the highest
level of spirited driving. The
