Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehicle’s
overall fuel economy during normal driving conditions.
Push the “ECO” switch in the center stack of the instru-
ment panel to activate or disable ECO mode. A light on the
switch indicates when ECO mode is disabled.
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 overall driving performance will be more conserva-
tive.
Vehicles with Quadra-Lift air suspension will operate in
Aero mode over a broader speed range. Refer to the
section on Quadra-Lift for further information.
Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
Active Noise Cancellation If Equipped
Your vehicle is equipped with an Active Noise Cancellation
System. This system uses four microphones embedded in
the headliner to detect undesirable exhaust noise, which
sometimes occurs when operating in specific driving con-
ditions such as ECO and Tow mode. An onboard frequency
generator creates counteracting sound waves through the
audio system to help keep the vehicle quiet.
Eight–Speed Automatic Transmission
The transmission gear range (PRNDM) is displayed both
beside the gear selector and in the instrument cluster. To
select a gear range, press the lock button on the gear
selector and move the selector rearward or forward. To
shift the transmission out of PARK, the engine must be
running and the brake pedal must be pressed. You must
also press the brake pedal to shift from NEUTRAL into
