Jeep Grand Cherokee 2015, Operating Information Manual

•
When disengaging Rear E-Locker, the in-
dicator lights in the instrument cluster
and on the REAR LOCK button will begin
to flash. When the shift is complete the
REAR LOCK indicator lights will remain
off.
•
Shifting into or out of Rear E-Locker is
possible with the vehicle completely
stopped; however, difficulty may occur
due to the mating clutch teeth not being
properly aligned. Several attempts may
be required for clutch teeth alignment and
shift completion to occur. The preferred
method is for the vehicle to be rolling,
below 15 MPH (24 km/h), while including
right and left steering maneuvers to allow
for the clutch teeth to align.
•
The Rear E-Locker System must be dis-
engaged prior to taking the vehicle out of
4WD LOW range. If 4WD LOW shift
conditions/interlocks are not met, a mes-
sage will flash from the Electronic Vehicle
Information Center (EVIC)/Driver Informa-
tion Display (DID) with instructions on
how to complete the requested shift.
SELEC-TERRAIN™
Description
Selec-Terrain™ combines the capabilities of the
vehicle control systems, along with driver input,
to provide the best performance for all terrains.
Rotate the Selec-Terrain™ knob to select the
desired mode.
Selec-Terrain™ offers the following modes:
•
Auto — Fully automatic full time four-wheel
drive operation can be used on and off road.
Balances traction with seamless steering feel
to provide improved handling and accelera-
tion over two-wheel drive vehicles.
•
Snow — Tuning set for additional stability in
inclement weather. Use on and off road on
loose traction surfaces such as snow. When
in SNOW mode (depending on certain oper-
ating conditions), the transmission may use
second gear (rather than first gear) during
launches, to minimize wheel slippage.
•
Sport — This mode alters the transmission’s
automatic shift schedule for sportier driving.
Upshift speeds are increased to make full
use of available engine power.
NOTE:
SPORT mode is not available when 4WD
LOW is selected.
•
Sand/Mud — Off road calibration for use on
low traction surfaces such as mud, sand, or
wet grass. Driveline is maximized for traction.
Some binding may be felt on less forgiving
surfaces. The electronic brake controls are
set to limit traction control management of
throttle and wheel spin.
