mode availability and affected vehicle
subsystems are dependent upon vehicle trim
level, region, and optional features.
If the vehicle is in Normal mode or My
Mode it will stay in that mode through
future on/off cycles. If the vehicle is in any
other mode, it will return to Normal mode
when the vehicle is restarted. When each
mode is selected, a unique and persistent
indicator will be displayed on the
instrument cluster.
Mode Activation
To activate each mode, turn the MODE knob
on the center console.
Mode Descriptions
Normal Mode : Use for normal city and
highway driving to provide a smooth ride.
This setting provides balance between
comfort and handling. There is no persistent
indicator in the instrument cluster for
this mode.
Off-Road Mode : Use this mode only
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. The
accelerator pedal is tuned for off-road use.
If equipped, this mode also modifies
steering, suspension, active rear steer,
electric Four-Wheel Drive (e4WD), Electric
Vehicle Sound Enhancement (EVSE), Antilock
Brake System (ABS), Electronic Stability
Control (ESC), and Traction Control System
(TCS) performance.
For more information on off-road driving,
see Off-Road Driving 0 172.
Tow/Haul Mode : Use this mode
when hauling heavy loads to provide
increased performance and vehicle control.
Tow/Haul Mode adjusts the pedal map,
steering, active rear steer, suspension, and
TSC performance.
Driving and Operating
If the vehicle is turned off with Tow/Haul
mode active and then restarted within four
hours or less Tow/Haul will remain active.
Otherwise, the vehicle will start in
Normal mode.
For more information on Tow/Haul mode,
see Towing Equipment 0 265.
Terrain Mode : Use this mode when
traveling on very rough roads at very low
speeds, such as a two-track or heavily rutted
road where precise vehicle control is
required. This can also be used for pulling a
boat out of the water on a trailer.
When in Terrain mode, the vehicle
maximizes torque for better control at lower
speeds and over rough terrain. This mode
modifies accelerator pedal mapping, ABS and
TCS performance, EVSE, suspension, steering,
active rear steer, e4WD, and active braking.
Speed is limited to 80 km/h (50 mph) while
in Terrain mode.
When the vehicle comes to a stop on an
upward grade, Terrain mode will hold the
vehicle stationary until the driver presses
the accelerator pedal. Cruise control is
disabled when in Terrain mode.
