NOTE:The system will display the last known outside
temperature when starting the vehicle and may need to be
driven several minutes before the updated temperature is
displayed. Engine temperature can also affect the dis-
played temperature; therefore, temperature readings are
not updated when the vehicle is not moving.
ECO (Fuel Saver Mode) — If Equipped
The ECO message will display below the outside tempera-
ture in the instrument cluster display (if the audio system
is on the ECO indicator will override the audio information
display line if the Display Fuel Saver personal setting is
ON — see Personal Settings section). This message will
appear whenever you are driving in a fuel efficient manner.
This feature allows you to monitor when you are driving in
a fuel efficient manner, and it can be used to modify
driving habits in order to increase fuel economy.
Automatic Compass Calibration
This compass is self-calibrating, which eliminates the need
to set the compass manually. When the vehicle is new, the
compass may appear erratic, and the instrument cluster
display will display “CAL” until the compass is calibrated.
You may also calibrate the compass by completing one or
more 360–degree turns (in an area free from large metal or metallic objects) until the “CAL” message displayed in the
instrument cluster display turns off. The compass will now
function normally.
NOTE:
A good calibration requires a level surface and an
environment free from large metallic objects such as build-
ings, bridges, underground cables, railroad tracks, etc.
Manual Compass Calibration
If the compass appears erratic and the “CAL” indicator
does not appear in the instrument cluster display, you must
put the compass into the Calibration Mode manually as
follows:
1. Start the engine. Leave the gear selector in PARK in order to enter the instrument cluster display Program-
ming Menus.
2. Push the MENUbutton until Personal Settings
(Customer-Programmable Features) displays in the in-
strument cluster display.
3. Push the downarrow button until “Calibrate Compass”
displays in the instrument cluster display.
4. Push and release the rightarrow button to start the
calibration. The “CAL” indicator will display in the

WARNING!(Continued)
•The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase brak-
ing or steering efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the
traction afforded.
• The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
• The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user ’s safety or the safety of
others.
ABS is designed to function with the OEM tires. Modifica-
tion may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will turn on
when the ignition is turned to the ON/RUN mode and
may stay on for as long as four seconds. If the “Anti-Lock Brake Warning Light” remains on or
comes on while driving, it indicates that the anti-lock
portion of the brake system is not functioning and that
service is required. However, the conventional brake sys-
tem will continue to operate normally if the “Brake System
Warning Light” is not on.
If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “Anti-Lock Brake Warn-
ing Light” does not come on when the ignition is turned to
the ON/RUN mode, have the light repaired as soon as
possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), 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 driv-
ing conditions.
Your vehicle may also be equipped with Trailer Sway
Control (TSC) and Hill Descent Control (HDC).

SAFETY 215

Electronic Brake Force Distribution (EBD)
This function 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.
Brake System Warning Light
The red “Brake System Warning Light” will turn on when
the ignition is turned to 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 re-
quired. If the “Brake System Warning Light” does not come
on when the ignition is turned to 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 sys-
tem 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-lockbrake 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.
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 capa-
bilities 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.
Hill Start Assist (HSA)
The HSA system is designed to mitigate roll back from a
complete stop while on an incline. If the driver releases the
brake while stopped on an incline, HSA will continue to
hold the brake pressure for a short period. If the driver

For vehicles not equipped with an instrument cluster
display, perform the following steps:
1. Center the steering wheel (front wheels pointingstraight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate control four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an additional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off
Indicator Light” will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.Traction Control System (TCS)
This system 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 similar 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 torque to be applied to the wheel
that is not spinning. BLD may remain enabled even if TCS
and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counteract-
ing the over/under steer condition. Engine power may also
be reduced to help the vehicle maintain the desired path.
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

ESC Full Off
This mode is entered by pushing and holding the ESC OFF
switch for five seconds.
In theESC Full Off mode, the engine torque reduction
and stability features are disabled. Therefore, the enhanced
vehicle stability offered by ESC is unavailable. In an
emergency 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. When in
ESC Full Off mode, ESC and TCS, except for the
Brake Limited Differential (BLD) feature described in the
TCS section, are turned off until the vehicle reaches an
approximate speed of 40 mph (64 km/h). For speeds at or
exceeding approximately 40 mph (64 km/h) the ESC goes
into ESC Partial Off. When the vehicle speed drops below
35 mph (56 km/h), the ESC system goes back to ESC Full
Off. To turn ESC on again, momentarily push the ESC OFF
switch. This will restore normal “ESC On” mode of opera-
tion. The ESC Off Indicator Light” will always be illumi-
nated when ESC is in ESC Partial OffandESC full Off.
WARNING!
With the ESC in ESC Full Offmode, the engine
torque reduction and stability features offered by ESC
and ERM are disabled. In an emergency evasive ma-
neuver, the ESC and ERM systems will not engage to
assist in maintaining stability. The ESC Full Off
mode is intended for off-road use only.

SAFETY 221

NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand, or
gravel, it may be desirable to switch to the ESC Partial Off
mode by pushing the ESC Full Offswitch. Once the
situation requiring ESC to be switched to the ESC Partial
Off mode is overcome, turn ESC back on by momentarily
pushing the ESC Full Off switch. This may be done while
the vehicle is in motion.
The ESC will restore to normal ESC On mode after each
key on.
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 TCS is disabled, and the enhanced vehicle
stability offered by the ESC system is reduced.
• Trailer Sway Control (TSC) is disabled when the ESC
system is in the Partial Offmode. 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 turned to the ON 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 your authorized
dealer as soon as possible to have the problem diagnosed and
corrected.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated 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.

SAFETY 223

NOTE:
•The “ESC Activation/Malfunction Indicator Light” and
the “ESC OFF Indicator Light” come on momentarily
each time the ignition is turned ON.
• Each time the ignition is turned ON, the ESC system will
be on even if it was turned off previously.
• The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the cus-
tomer has elected to have the Electronic Stability
Control (ESC) in a reduced mode.
Electronic Roll Mitigation (ERM)
This system 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, or striking objects or other vehicles.
NOTE:
ERM is disabled anytime the ESC is in “Full Off”
mode (if equipped). Refer to “Electronic Stability Control
(ESC)” in this section for a complete explanation of the
available ESC modes.
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 ve-
hicles. 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.
