Performance Pages — G-Force

When selected, this screen displays all four
G-Force values as well as steering angle.
When G-Force is selected, the following features
will be available:
Vehicle Speed:
Measures the current speed of the vehicle in
either mph or km/h, starting at zero with no
maximum value.
Front G-Force:
Measures the peak braking force on the front of
the vehicle.
Right G-Force:
Measures the peak force on the right side of the
vehicle.
Left G-Force:
Measures the peak force on the left side of the
vehicle.
Rear G-Force:
Measures the peak acceleration force on the
rear of the vehicle.
NOTE:Front, Right, Left, and Rear G-Forces are all peak
values. These readings can be reset by clearing
peak G-Force on the instrument cluster.
Steering Wheel Angle
Steering Wheel Angle utilizes the steering angle
sensor to measure the degree of the steering
wheel relative to zero (straight ahead) reference
angle. The zero degree reference angle
measurement indicates a steering wheel
straight ahead position.
The friction circle display shows instantaneous
G-Force as a highlight and previous G-Force as
dots within the circle. The system records previous
G-Force for three minutes. If there are multiple
samples at a given point, the color of the dot will
darken from blue to red. Vectors more frequent will
show in red; infrequent vectors will show in blue.

Launch Control

Launch Control
This vehicle is equipped with a Launch Control
system that is designed to allow the driver to achieve
quick, consistent vehicle acceleration in a straight
line. Launch Control is a form of traction control
that manages tire slip while launching the vehicle.
This feature is intended for use during race events
on a closed course where consistent quarter-mile
and 0-to-60 times are desired. The system is not
intended to compensate for lack of driver experience
or familiarity with the race track. Use of this feature
in low traction (cold, wet, gravel, etc.) conditions may
result in excess wheel slip outside this system’s
control resulting in an aborted launch.

WARNING!
Launch Mode is intended for off-highway or
off-road use only and should not be used on any
public roadways. It is recommended that this
feature be used in a controlled environment, and
within the limits of the law. The capabilities of
the vehicle as measured by the performance
pages must never be exploited in a reckless or
dangerous manner, which can jeopardize the
user’s safety or the safety of others. Only a safe,
attentive, and skillful driver can prevent
accidents.

ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM

Your vehicle is equipped with an advanced Electronic
Brake Control (EBC) system. This system includes
Electronic Brake Force Distribution (EBD), Anti-Lock
Brake System (ABS), Brake Assist System (BAS), Hill
Start Assist (HSA), Traction Control System (TCS),
Electronic Stability Control (ESC), and Electronic Roll
Mitigation (ERM). These systems work together to
enhance both vehicle stability and control in various
driving conditions.

Your vehicle may also be equipped with Ready
Alert Braking (RAB) and Rain Brake Support (RBS).
Brake System Warning Light
The red Brake System Warning Light will turn on
when the ignition is placed in the ON/RUN mode
and may stay on for as long as four seconds.
If the Brake System Warning Light remains on
or comes on while driving, it indicates that the
brake system is not functioning properly and that
immediate service is required. If the Brake System
Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application and then applies optimum
pressure to the brakes. This can help reduce
braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes
very quickly results in the best BAS assistance.
To receive the benefit of the system, you must
apply continuous braking pressure during the
stopping sequence (do not “pump” the brakes).
Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake
pedal is released, the BAS is deactivated.
Electronic Brake Force Distribution (EBD)
EBD manages the distribution of the braking
torque between the front and rear axles by limiting
braking pressure to the rear axle. This is done to
prevent overslip of the rear wheels to avoid vehicle
instability, and to prevent the rear axle from
entering ABS before the front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When ERM determines
that the rate of change of the steering wheel angle
and vehicle’s speed are sufficient to potentially
cause wheel lift, it then applies the appropriate
brake and may also reduce engine power to lessen
the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during
severe or evasive driving maneuvers; it cannot
prevent wheel lift due to other factors, such as
road conditions, leaving the roadway, striking
objects or other vehicles.
NOTE:ERM is disabled any time the ESC is in “Full Off”
mode (if equipped). See Ú page 182 for a
complete explanation of the available ESC modes.
WARNING!

The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. BAS cannot prevent collisions,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. The capabilities of a BAS-equipped
vehicle must never be exploited in a reckless or
dangerous manner, which could jeopardize the
user's safety or the safety of others.

182SAFETY
(Continued)
Electronic Stability Control (ESC)
ESC enhances directional control and stability
of the vehicle under various driving conditions.
ESC corrects for oversteering or understeering
of the vehicle by applying the brake of the
appropriate wheel(s) to counteract the above
conditions. Engine power may also be reduced to
help the vehicle maintain the desired path.
Oversteer — when the vehicle is turning more
than appropriate for the steering wheel position.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the
vehicle path intended by the driver and compares
it to the actual path of the vehicle. When the actual
path does not match the intended path, ESC
applies the brake of the appropriate wheel to
assist in counteracting the above conditions.
The ESC Activation/Malfunction Indicator Light
located in the instrument cluster will start to flash as
soon as the ESC system becomes active. The ESC
Activation/Malfunction Indicator Light also flashes
when the TCS is active. If the ESC Activation/
Malfunction Indicator Light begins to flash during
acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road conditions.

ESC Operating Modes
Depending upon model and mode of operation, the
ESC system may have multiple operating modes.
"ESC On"
This is the normal operating mode for the ESC.
Whenever the vehicle is started, the ESC system
will be in this mode. This mode should be used for
most driving conditions. Alternate ESC modes
should only be used for specific reasons as noted
in the following paragraphs.
WARNING!

Many factors, such as vehicle loading, road
conditions and driving conditions, influence the
chance that wheel lift or rollover may occur. ERM
cannot prevent all wheel lift or roll overs, especially
those that involve leaving the roadway or striking
objects or other vehicles. The capabilities of an
ERM-equipped vehicle must never be exploited
in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

WARNING!

Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions.
ESC cannot prevent accidents, including those
resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC
also cannot prevent accidents resulting from
loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe,
attentive, and skillful driver can prevent acci
-
dents. The capabilities of an ESC equipped
vehicle must never be exploited in a reckless or
dangerous manner which could jeopardize the
user’s safety or the safety of others.

Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and size
or wheel size may adversely affect ESC perfor -
mance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any
vehicle modification or poor vehicle mainte -
nance that reduces the effectiveness of the
ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
WARNING!

"Partial Off"
This mode may be useful if the vehicle becomes
stuck. This mode may modify TCS and ESC
thresholds for activation, which allows for more
wheel spin than normally allowed.
To enter the “Partial Off” mode, momentarily push
the ESC OFF button and the ESC OFF Indicator
Light will illuminate. To turn the ESC on again,
momentarily push the ESC OFF button and the ESC
OFF Indicator Light will turn off.
NOTE:
For vehicles with multiple partial ESC modes,
the push and release of the button will toggle
the ESC modes. Multiple attempts may be
required to return to "ESC On" mode.
Trailer Sway Control (TSC) is disabled when the
ESC system is in the “Partial Off” mode.
If Equipped — "ESC Sport" and "ESC Track" are
ESC “Partial Off” mode(s). “Full Off” – If Equipped

This mode is intended for off-highway or off-road use
only and should not be used on any public roadways.
In this mode, TCS and ESC features are turned off.
To enter the “Full Off” mode, push and hold the ESC
OFF button for five seconds while the vehicle is stopped
with the engine running. After five seconds, a chime will
sound, the ESC OFF Indicator Light will illuminate, and
the ESC OFF message will display in the instrument
cluster. To turn ESC on again, momentarily push the
ESC OFF button.

ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator
Light in the instrument cluster will come
on when the ignition is placed in the
ON/RUN mode. It should go out with the
engine running. If the ESC Activation/Malfunction
Indicator Light comes on continuously with the
engine running, a malfunction has been detected
in the ESC system. If this light remains on after
several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater
than 30 mph (48 km/h), see an authorized dealer
as soon as possible to have the problem
diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light
(located in the instrument cluster) starts to flash as
soon as the tires lose traction and the ESC system
becomes active. The ESC Activation/Malfunction
Indicator Light also flashes when TCS is active.
If the ESC Activation/Malfunction Indicator Light
begins to flash during acceleration, ease up on the
accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the
prevailing road conditions.
The ESC OFF Indicator Light indicates
the customer has elected to have the
Electronic Stability Control (ESC) in a
reduced mode.
WARNING!

When in “Partial Off” mode, the TCS functionality of
ESC, except for the limited slip feature described in
the TCS section, has been disabled and the ESC OFF
Indicator Light will be illuminated. When in “Partial
Off” mode, the engine power reduction feature of
Traction Control System (TCS) is disabled, and the
enhanced vehicle stability offered by the ESC system
is reduced.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled.
Therefore, enhanced vehicle stability offered
by the ESC system is unavailable. In an emer -
gency evasive maneuver, the ESC system will
not engage to assist in maintaining stability.
ESC “Full Off” mode is intended for
off-highway or off-road use only.
The Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road condi -
tions. ESC cannot prevent all accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent collisions.

SAFETY185
Rain Brake Support (RBS)
RBS may improve braking performance in wet
conditions. It will periodically apply a small amount
of brake pressure to remove any water buildup
on the front brake rotors. It functions when the
windshield wipers are in LO or HI speed. When RBS
is active, there is no notification to the driver and
no driver interaction is required.
Ready Alert Braking (RAB)

RAB may reduce the time required to reach full braking
during emergency braking situations. It anticipates
when an emergency braking situation may occur by
monitoring how fast the throttle is released by the
driver. The Electronic Brake Controller (EBC) will
prepare the brake system for a panic stop.

Traction Control System (TCS)

The TCS monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS
may apply brake pressure to the spinning wheel(s)
and/or reduce engine power to provide enhanced
acceleration and stability. A feature of the TCS, Brake
Limited Differential (BLD) functions similarly to a
limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
power to be applied to the wheel that is not spinning.
BLD may remain enabled even if TCS and ESC are in
reduced modes.

AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BS M) —
I
F EQUIPPED
The BSM system uses two radar sensors, located
inside the rear fascia/bumper, to detect highway
licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning
Light will momentarily illuminate in both outside
rearview mirrors to let the driver know that the
system is operational.
The BSM system sensors operate when the vehicle
is in any forward gear or REVERSE.
BSM Warning Light
The BSM detection zone covers approximately one
lane width on both sides of the vehicle 12 ft (3.8 m).
The zone length starts at the outside rearview mirror
and extends approximately 10 ft (3 m) beyond the
rear fascia/bumper of the vehicle. The BSM system
monitors the detection zones on both sides of
the vehicle when the vehicle speed reaches
approximately 6 mph (10 km/h) or higher and
will alert the driver of vehicles in these areas.

NOTE:
The BSM system DOES NOT alert the driver
about rapidly approaching vehicles that are
outside the detection zones.
The BSM system detection zone DOES NOT
change if your vehicle is towing a trailer. There -
fore, visually verify the adjacent lane is clear for
both your vehicle and trailer before making a
lane change. If the trailer or other object (i.e.,
