• To disengage Paddle Shift Mode, press and hold the (+) shift paddle until "D" is
once again displayed in the instrument cluster. You can shift in or out of the Paddle
Shift Mode at any time without taking your foot off the accelerator pedal.
Do not downshift for additional engine braking on a slippery surface. The drive
wheels could lose their grip and the vehicle could skid, causing a collision or
personal injury.

FUEL ECONOMY (ECO) MODE

The Fuel Economy (ECO) mode can improve the vehicle's overall fuel economy during
normal driving conditions. Press the "ECO" switch in the center stack of the
instrument panel and an amber light will indicate the ECO mode is engaged.
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 en-
gage at lower engine speeds and re-
main on longer.
• The engine idle speed will be lower.
• The overall driving performance will
be more conservative.
• Some ECO mode functions may be
temporarily inhibited based on temperature and other factors.
NOTE:
ECO mode is only available in AUTO mode.
Active Noise Cancellation
Your vehicle is equipped with an Active Noise Cancellation System, this system is
designed to address the change in exhaust noise whenever the vehicle is operating in
Fuel Economy Mode (ECO) or 4 cylinder mode.
This system relies on four microphones embedded in the headliner to detect the
exhaust drone and prompt an onboard frequency generator to create counteracting
sound waves through the audio system's speakers and sub-woofer. This helps keep
the vehicle quiet at highway speeds.
