STARTING AND OPERATING155
NOTE:In the event of a mismatch between the gear
selector position and the actual transmission gear
(for example, driver selects PARK while driving),
the position indicator will blink continuously until
the selector is returned to the proper position, or
the requested shift can be completed.
The electronically controlled transmission adapts
its shift schedule based on driver inputs, along
with environmental and road conditions. The
transmission electronics are self-calibrating;
therefore, the first few shifts on a new vehicle may
be somewhat abrupt. This is a normal condition,
and precision shifts will develop within a few
hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE when
the accelerator pedal is released and the vehicle is
stopped. Be sure to keep your foot on the brake
pedal when shifting between these gears.
The transmission gear selector has only PARK,
REVERSE, NEUTRAL, and DRIVE positions. Manual
downshifts can be made using the Electronic
Range Select (ERS) shift control. Pushing the
GEAR “-”/GEAR “+” switches (on the steering
wheel) while in the DRIVE position will select the
highest available transmission gear, and will
display that gear limit in the instrument cluster as
1, 2, 3, etc. Úpage 158. Some models will display
both the selected gear limit, and the actual current
gear, while in ERS mode.
Electronic Transmission Gear Selector
Console Shifter — If Equipped
The transmission gear range is displayed both
beside the gear selector and in the instrument
cluster. To select a gear range, push the lock
button on the gear selector and move the selector
rearward or forward. To shift the transmission out
of PARK (P), the engine must be running and the
brake pedal must be pressed. You must also press
the brake pedal to shift from NEUTRAL (N) into
DRIVE (D) or REVERSE (R) when the vehicle is
stopped or moving at low speeds. Select the DRIVE
range for normal driving.
NOTE:
The transmission electronics are self-calibrating;
therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal condi -
tion, and precision shifts will develop within a
few hundred miles (kilometers).
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects PARK while
driving), the position indicator will blink continu -
ously until the selector is returned to the proper
position, or the requested shift can be
completed.
The electronically controlled transmission adapts
its shift schedule based on driver inputs, along
with environmental and road conditions.
Only shift from DRIVE to PARK or REVERSE when
the accelerator pedal is released and the vehicle is
stopped. Be sure to keep your foot on the brake
pedal when shifting between these gears.
The transmission gear selector provides PARK,
REVERSE, NEUTRAL, and SPORT (S) (AutoStick)
shift positions. Manual shifts can be made using
the AutoStick shift control. Toggling the gear
selector forward (-) or rearward (+) while in the
SPORT (AutoStick) position (beside the DRIVE
position), or tapping the paddle shifters (+/-)
(if equipped), will manually select the transmission
gear, and will display the current gear in the
instrument cluster Ú page 159.

STARTING AND OPERATING159
Electronic Range Select (ERS)
To exit ERS mode, simply push and hold the “+”
button until the gear limit display disappears from
the instrument cluster.
AutoStick — If Equipped
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall
vehicle performance. This feature can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing, and many other situations.
Paddle Shifters
Operation
In AutoStick mode, you can use the gear selector
(in the SPORT position), or the paddle shifters, to
manually shift the transmission. To activate
AutoStick mode, move the gear selector into the
SPORT (S) position (beside the DRIVE position), or
tap one of the paddle shifters on the steering
wheel. Tapping the “-” shift paddle to enter AutoStick mode will downshift the transmission to
the next lower gear, while tapping “+” to enter
AutoStick mode will retain the current gear. The
current transmission gear will be displayed in the
instrument cluster.
AutoStick mode has the following operational
benefits:
The transmission will automatically downshift
as the vehicle slows (to prevent engine lugging)
and will display the current gear.
The transmission will automatically downshift to
FIRST gear when coming to a stop. After a stop,
the driver should manually upshift “+” the trans
-
mission as the vehicle is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear (or THIRD gear, in 4WD LOW).
Tapping “+” (at a stop) will allow starting in
SECOND gear. Starting out in SECOND or THIRD
gear can be helpful in snowy or icy conditions.
If a requested downshift would cause the
engine to over-speed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed.
Holding the “-” paddle pressed, or holding the
gear selector in the “-” position, will downshift
the transmission to the lowest gear possible at
the current speed.
1 — Shift Up “+”
2 — Shift Down “–”
WARNING!
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.

NOTE:Default Ride Height:
Select Aero Height or Normal Ride Height as the
default for all vehicle speeds and operation.
This is the selected height that the suspension
will level for speed changes (e.g. raising from
Entry/Exit Height at speed, lowering from Off
Road Height at speed, etc.).
Default ride height can be changed by manually
adjusting the Air Suspension switch to Normal
Ride Height or Aero Ride Height and staying in
the selected height for 2.5 seconds. It will be
stored as the default ride height and the height
will be maintained until a new default ride
height is selected.

AXLE LOCK SYSTEM — IF EQUIPPED
This vehicle is equipped with an electronically
locking rear differential. When engaged, this
differential locks the axle shafts forcing the wheels
to spin at an equal rate. The locking of the rear
differential should only be engaged during
low-speed, extreme off-road situations where one
wheel is likely to not be in contact with the ground.
It is not recommended to drive the vehicle with the
differentials locked on pavement due to the
reduced ability to turn and speed limitations.
AXLE LOCK Button
The locking rear axle is controlled by the AXLE
LOCK button.
Under normal driving conditions, the rear axle
should be unlocked.
During the command to lock the rear axle, the
indicator light will flash until the axle is locked.
After the lock command has been successfully
executed, the light will remain on solid.
Operating in 4WD LOW the locker can be engaged
up to 40 mph (64 km/h) and will remain engaged
throughout the 4WD LOW speed range.
CAUTION!
Do not lock the rear axle on hard surfaced
roads. The ability to steer the vehicle is
reduced and damage to the drivetrain may
occur when the axle is locked on hard
surfaced roads.
Do not try to lock the rear axle if the vehicle is
stuck and the tires are spinning. You can
damage drivetrain components. Lock the rear
axle before attempting situations or navi
-
gating terrain, which could possibly cause the
vehicle to become stuck.
