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 0 166.
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.
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 0 270.
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.
Driving and Operating
Terrain mode automatically exits to Normal
Mode if the brake temperatures become too
hot, electronic parking brake becomes
inoperable, or the vehicle cannot perform
braking or vehicle hold.
Active Braking engages when the driver lifts
their foot off the accelerator while in Terrain
mode. This feature applies light braking in D
(Drive) and aggressive braking in L (Low) in
order to tailor the level of vehicle control to
the driver s preference.
For more information on off-road driving,
see Off-Road Driving 0 166 and
Hill and Mountain Roads 0 174.
My Mode : My Mode is used to
personalize everyday driving. This mode
allows the driver to configure the driver
systems to their driving preferences.
If available, this mode modifies electric
vehicle pedal map, steering, suspension, and
sound performance. My Mode will remain
active across on/off cycles.
Through the infotainment display, the
following vehicle sub-systems may be
available for customization in this mode:
Acceleration : Relaxed, Normal, Adrenaline
Steering : Normal, Tow/Haul, Terrain
