For further information, refer to “Adaptive Cruise Con-
trol (ACC)” in “Understanding The Features Of Your
Vehicle”.
•Forward Collision Warning (FCW) — Active Braking
The FCW system includes Advanced Brake Assist (ABA).
When this feature is selected, the ABA applies additional
brake pressure when the driver requests insufficient
brake pressure to avoid a potential frontal collision. The
ABA system becomes active at 5 mph (8 km/h). To make
your selection, touch the “Forward Collision Warning
(FCW) with Mitigation - Active Braking” soft-key, until a
check-mark appears next to setting, indicating that the
setting had been selected. Touch the back arrow soft-key
to return to the previous menu. For further information,
refer to “Forward Collision Warning (FCW) With Mitiga-
tion” in “Understanding The Features Of Your Vehicle.” •
Lane Departure Warning (LDW) — If Equipped
The Lane Departure Warning (LDW) sets the distance at
which the steering wheel will provide feedback for
potential lane departures. The LDW sensitivity can be set
to provide either an early, medium or late warning zone
start point. To make your selection, touch the “Lane
Departure Warning” soft-key, until a check-mark appears
next to setting, indicating that the setting had been
selected. Touch the back arrow soft-key to return to the
previous menu.
• Lane Departure Warning (LDW) Strength —
If Equipped
When this feature is selected, it sets the strength of the
steering wheel feedback for potential lane departures.

apply to the steering wheel to correct for vehicle lane

When the Fuel Economy (ECO) Mode is engaged, the
vehicle control systems will change the following:
•The transmission will upshift sooner and downshift
later.
• The transmission will launch (from a stop) in second
gear.
• The torque converter clutch may engage at lower
engine speeds and remain on longer.
• The engine idle speed will be lower.
• The overall driving performance will be more conser-
vative.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
NOTE: ECO mode is only available in AUTO mode.Eight–Speed Automatic Transmission
Your vehicle is equipped with a state of the art, fuel
efficient eight-speed transmission. The electronic shift
lever in this vehicle does not slide like a conventional
shifter. Instead, the shift lever is spring loaded and moves
forward and rearward, always returning to the center
position after each gear is selected. The transmission gear
(PRND) is displayed both on the shift lever and in the
Electronic Vehicle Information Center (EVIC). To select a
gear range, press the lock button on the shift lever and
move the lever rearward or forward. You must also press
the brake pedal to shift the transmission out of PARK, or
to shift from NEUTRAL into DRIVE or REVERSE when
the vehicle is stopped or moving at low speeds (refer to
“Brake/Transmission Shift Interlock System” in this sec-
tion). To shift past multiple gear ranges at once (such as
PARK to DRIVE), move the lever past the first (or second)
detent. Select the DRIVE range for normal driving.

WARNING!
The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
ABS cannot prevent collisions, including those result-
ing from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. The capabilities of
an ABS-equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopardize
the user’s safety or the safety of others.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each
of the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability.A feature of the TCS system, 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. This feature remains active even if
ESC system is in the “Partial Off” mode. Refer to “Elec-
tronic Stability Control (ESC)” in this section for further
information.
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 sens-
ing 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

NOTE:TheESC OFF message will display and the
audible chime will sound when the shift lever is moved
into the PARK position from any position other than
PARK and then moved out of the PARK position. This
will occur when the message was previously cleared.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled. There-
fore, 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 Off mode is intended for off-highway
or off-road use only.
NOTE: When the ESC is switched OFF, a feature of the
system remains active. This feature controls wheel spin
across an axle quite similarly to a limited slip differential. If one wheel on an axle is spinning faster than the other,
the system will apply the brake of the spinning wheel
and allow more engine torque to be applied to the wheel
that is not spinning. To improve the vehicle’s traction
when driving with tire chains, or when starting off in
deep snow, sand, or gravel, it may be desirable to switch
to the “Partial Off” mode by momentarily pressing the
“ESC Off” switch.
WARNING!
With the ESC switched OFF, the enhanced vehicle
stability offered by ESC is unavailable. In an emer-
gency evasive maneuver, the ESC system will not
engage to assist in maintaining stability. The “Full
Off” ESC mode is intended for off-highway or off-
road only.

CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on HOT
(H), and you hear continuous chimes, turn the engine
off immediately and call for service.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

WHAT TO DO IN EMERGENCIES 485

Inspect the wheel mounting surface prior to mounting
the tire and remove any corrosion or loose particles.Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice.
After 25 miles (40 km) check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated
against the wheel.
