84STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission
automatically upshifts through all forward gears.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong head
winds, or while towing a heavy trailer), use the AutoStick
shift control to select a lower gear
Úpage 84. Under
these conditions, using a lower gear will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the
transmission shift schedule, reduce engine torque, and/or
expand the range of torque converter clutch engagement.
This is done to prevent transmission damage due to
overheating.
If the transmission becomes extremely hot, the
Transmission Temperature Warning Light may illuminate,
and the transmission may operate differently until the
transmission cools down.
During cold temperatures, transmission operation may be
modified depending on engine and transmission
temperature as well as vehicle speed. This feature
improves warm-up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch, and shifts into EIGHTH or NINTH gear,
are inhibited until the transmission fluid is warm
Úpage 85. Normal operation will resume once the
transmission temperature has risen to a suitable level.
SPORT — If Equipped
This mode alters the transmission's automatic shift
schedule for sportier driving. Upshift speeds are increased
to make full use of available engine power.
SPORT mode is activated using the rotary switch on the
center console
Úpage 88.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
mode is activated. In this mode, the transmission may
operate only in a fixed gear, or may remain in NEUTRAL.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home mode may allow the vehicle to be driven to an
authorized dealer for service without damaging the
transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK.
3. Turn the ignition to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to
normal operation.
NOTE:Even if the transmission can be reset, we recommend that
you visit an authorized dealer at your earliest possible convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission. If
the transmission cannot be reset, authorized dealer
service is required.
AutoStick
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.
Operation
When the gear selector is in the AutoStick position (beside
the DRIVE position), it can be moved forward and
rearward. This allows the driver to manually select the
transmission gear being used. Moving the gear selector
forward (-) triggers a downshift, and rearward (+) an
upshift. The current gear is displayed in the instrument
cluster.
NOTE:
In AutoStick mode, the transmission will only shift up or
down when the driver moves the gear selector rearward (+)
or forward (-), except as follows:


The transmission will automatically upshift when
necessary to prevent engine overspeed.
 The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.

23_KL_OM_EN_USC_t.book Page 84

88STARTING AND OPERATING
SELEC-TERRAIN
DESCRIPTION
Selec-Terrain allows the driver to specify the driving
surface to allow the vehicle systems to provide the best
performance possible across a wide range of conditions.
Rotate the Selec-Terrain knob to select the desired mode.

Selec-Terrain Switch

Selec-Terrain offers the following modes:
AUTO — Fully automatic, full-time four-wheel drive oper -
ation can be used on and off-road. Balances traction
with a seamless steering feel to provide improved
handling and acceleration.
 SNOW — Tuning set for additional stability in inclement
weather. Use when driving on loose traction surfaces
such as snow, while either on or off-road. When in
SNOW mode (depending on certain operating condi -tions), the transmission may use SECOND gear (rather
than FIRST gear) during launches, to minimize wheel
slippage.
 SPORT — This mode alters the transmission's auto -
matic 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 trac -
tion surfaces such as mud, sand, or wet grass. The
4WD system provides maximum capability to all
wheels. Some binding may be felt on high traction
surfaces. The electronic brake system will be adjusted
to reduce the automatic braking of slipping wheels and
to allow the engine to operate without restriction.
 ROCK — Off-road calibration is only available in 4WD
LOW range. ROCK mode provides the most aggressive
four-wheel drive performance for extreme off-road
terrain. Use for low speed obstacles such as large
rocks, deep ruts, etc. The driver may notice additional
tire scrubbing and steering wheel feedback while
driving in ROCK mode on higher traction off-road
surfaces. For use only in off-road driving situations.
NOTE:
 ROCK mode is only available on the vehicles equipped
with the Off-Road package.
 Activate the Hill Descent Control or Selec-Speed
Control for steep downhill control
Úpage 143.
Instrument Cluster Display Messages
When the appropriate conditions exist, a message will
appear in the instrument cluster Úpage 63.
POWER STEERING
The power steering system will provide increased vehicle
response and ease of maneuverability. The power steering
system adapts to different driving conditions.
If the “SERVICE POWER STEERING” or “POWER
STEERING ASSIST OFF - SERVICE SYSTEM”
message and a steering wheel icon are
displayed on the instrument cluster display
screen, it indicates that the vehicle needs to be taken to
an authorized dealer for service. It is likely the vehicle has
lost power steering assistance
Úpage 68.
If the “POWER STEERING SYSTEM HOT - PERFORMANCE
MAY BE LIMITED” message and an icon are displayed on
the instrument cluster display screen, it indicates that
extreme steering maneuvers may have occurred, which
caused an over temperature condition in the power
steering system. You will lose power steering assistance
momentarily until the over temperature condition no
longer exists. Once driving conditions are safe, pull over
and let the vehicle idle for a few moments until the light
turns off
Úpage 68.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, or extremely hot or cold
ambient temperatures will influence when the “Oil Change
Required” message is displayed. Have your vehicle
serviced as soon as possible, within the next 500 miles
(805 km).An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
an authorized dealer, the message can be reset by
referring to the steps described under Instrument Cluster
Display
Úpage 64.
NOTE:Under no circumstances should oil change intervals
exceed 10,000 miles (16,000 km), 12 months or
350 hours of engine run time, whichever comes first. The
350 hours of engine run or idle time is generally only a
concern for fleet customers.
At Every Fuel Stop:

Check engine oil level.
 Check windshield washer fluid level.
 Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular wear,
even if it occurs before the oil indicator system turns
on.
 Check the fluid levels of the coolant reservoir and
brake master cylinder; fill as needed.
 Check function of all interior and exterior lights.
