longer than two seconds,
or press twice in five seconds.
Accessory Mode (Amber
Indicator Light) : This mode
allows you to use some
electrical accessories when
the engine is off.
With the ignition off, pressing
ENGINE START/STOP once
without the brake pedal
applied will place the ignition
system in accessory mode.
The ignition will switch from

This mode is
for driving and starting. With
the ignition off and the brake
pedal applied, pressing
ENGINE START/STOP once
will place the ignition system in
ON/RUN/START. Once engine

Permanent Tap Shift Mode
To enter Permanent Tap
Shift Mode:1. With the vehicle in D (Drive), pull back on the
shift lever to activate
M (Manual Mode). The M in
the shift pattern will
illuminate in red, and the D
will switch to white.
2. After releasing the shift lever, it will return to the
center position.
3. Pull the control toward you to shift. Pull the left
control to downshift, and
the right control to upshift.
To exit Permanent Tap
Shift Mode: 1. To exit M (Manual Mode) and return to D (Drive), pull
back on the shift lever. The
D in the shift pattern will
illuminate in red, and the M
will switch to white.
2. After releasing the shift lever, it will return to the
center position. M (Manual Mode) can be exited
to return to D (Drive) at any
speed by pulling the lever
rearward from the center
position. It is not necessary to
stop the vehicle or shift to
N (Neutral) or P (Park) prior to
shifting back to D (Drive).
Temporary Tap Shift Mode
To enter Temporary Tap
Shift Mode:
1. With the transmission in D (Drive) and not in
Permanent Tap Shift
Mode, the Tap Shift
controls will activate a
Temporary Tap Shift
Mode, allowing the
transmission to be
manually shifted.
2. To deactivate, hold the right control briefly.
Automatic shifts return
after no manual shifts have
been done for seven to
10 seconds. While using Tap Shift, the
vehicle will have firmer, quicker
shifting. This can be used for
sport driving or when climbing
or descending hills, to stay in
gear longer, or to downshift
for more power or engine
braking.
The transmission will only
allow shifting into gears
appropriate for the vehicle
speed and engine revolutions
per minute (rpm). If shifting is
prevented for any reason, the
M or D will flash in the
instrument cluster. The
transmission will not
automatically shift to the next
higher gear if the engine rpm
is too high. It will only
automatically shift to the next
lower gear if the engine rpm is
much too low.

If the vehicle is in Tour or
AWD, it will stay in that mode
through future ON/OFF
cycles. If the vehicle is in any
other mode, it will return to
Tour Mode when the vehicle is
restarted. When a mode is
selected, an indicator will
come on in the instrument
cluster and stay on.
Driver Mode Control Switch
Tour : Tour Mode operates in
FWD to improve fuel economy.
Use this mode during normal
driving operations. Sport :
Sport Mode improves
vehicle handling and
acceleration on dry pavement.
When active, Sport Mode
modifies steering efforts,
transmission shifting, AWD,
ESC, and suspension tuning,
if equipped.
The Performance Algorithm
Liftfoot (PAL) feature is
enabled in Sport Mode. PAL
allows the transmission to
hold the current gear after a
quick release of a heavily
applied accelerator pedal. This
provides greater engine
braking and enhanced vehicle
control.
When PAL is activated, there
may be an additional green
gear symbol which appears in
the instrument cluster display.
See Performance Shifting
Light 0138.
AWD : AWD Mode provides
drive torque to all four wheels.
Select AWD to improve
traction and control on
slippery road surfaces, such as gravel, sand, wet pavement,
snow, and ice. When in AWD
Mode, the AWD Mode
indicator light will be on. For
more information on AWD
Mode, see All-Wheel Drive

Snow/Ice (FWD Vehicles
Only) : Snow/Ice Mode
improves vehicle acceleration
on snow and ice covered
roads.
Off-Road (AWD Vehicles
Only) : Use this mode for
off-road recreational driving.
Off-Road Mode should be
used to improve driving at
moderate speeds, on grass,
gravel, dirt, unpaved roads,
or snow-covered roads. This
mode modifies pedal mapping,
suspension tuning, AWD, ABS,
ESC, and TCS performance.
For more information on
off-road driving, see Off-Road
