MAX A/C
For maximum cooling, when MAX A/C is selected the
A/C is turned on automatically and the air is
recirculated.
NOTE:A/C cannot be deselected when in MAX A/C
position. The LED will blink three times if the A/C
button is pushed. If your air conditioning performance
seems lower than expected, check the front of the A/C
condenser (located in front of the radiator), for an accu-
mulation of dirt or insects. Clean with a gentle water
spray from behind the radiator and through the con-
denser. Fabric front fascia protectors may reduce airflow
to the condenser, reducing air conditioning performance.
Mode Control (Air Direction)
Mode control allows you to choose
from several patterns of air distribu-
tion. You can select either a primary
mode, as identified by the symbols, or
a blend of two of these modes. The
closer the control is to a particular
mode, the more air distribution you
receive from that mode.
Panel Mode
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted to direct
airflow.

3. Recirculation Button
Press and release to change the current setting; the
indicator illuminates when ON.
4. Front Defrost Button
Press and release to change the current airflow setting to
Defrost mode. The indicator illuminates when this fea-
ture is ON. Air comes from the windshield and side
window demist outlets. When the defrost button is
selected, the blower level will increase. Use Defrost mode
with maximum temperature settings for best windshield
and side window defrosting and defogging. Performing
this function will cause the ATC to switch into manual
mode. If the front defrost mode is turned off the climate
system will return the previous setting.
5. Rear Defrost Button
Press and release this button to turn on the rear window
defroster (if equipped) and the heated outside mirrors (ifequipped). An indicator will illuminate when the rear
window defroster is on. The rear window defroster
automatically turns off after 10 minutes.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to the
heating elements. Labels can be peeled off after
soaking with warm water.
•Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the
window.
•Keep all objects a safe distance from the window.4

•If fog or mist appears on the windshield or side glass,
select Defrost mode and adjust blower speed if
needed.
•If your air conditioning performance seems lower than
expected, check the front of the A/C condenser (lo-
cated in front of the radiator), for an accumulation of
dirt or insects. Clean with a gentle water spray from
behind the radiator and through the condenser. Fabric
front fascia protectors may reduce airflow to the
condenser, reducing air conditioning performance.
MAX A/C
MAX A/C sets the control for maximum cooling perfor-
mance.
Press and release to toggle between MAX A/C and the
prior settings. The button on the touchscreen illuminates
when MAX A/C is ON.In MAX A/C, the blower level and mode position can be
adjusted to desired user settings. Pressing other settings
will cause the MAX A/C operation to switch to the prior
settings and the MAX A/C indicator will turn off.
Recirculation Control
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the RECIRCULATION control button
on the touchscreen or faceplate. Recirculation mode
should only be used temporarily. The recirculation LED
button on the faceplate will illuminate when either
button is selected. Push either button a second time to
turn off the Recirculation mode LED and allow outside
air into the vehicle.

Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, can cause
odor, and if they enter the plenum they could plug the
water drains. In winter months, ensure the air intake is
clear of ice, slush and snow.

ramp without lifting any other wheel off the ground. This
distance up the ramp divided by the wheelbase of the
vehicle and multiplied by 1,000 is the RTI. This vehicle
has an RTI of 510, which means you can articulate one
front wheel 26 inches (66 cm) in the air while the other
three wheels remain in contact with the ground.
Water Fording Characteristics
Water fording characteristic is the vehicle’s ability to
cross a body of still water, where the powertrain and
drivetrain are safe from water ingestion. This vehicle has
high water fording characteristics with the ability to cross
a pool of water, without stopping, 24 inches (60 cm) deep
at a maximum speed of 10 mph (16 km/h) and a pool of
water 30 inches (76 cm) deep at a maximum speed of
5 mph (8 km/h), both with an entrance ramp angle of 1.3
degrees.
CAUTION!
The door sill height is 25 inches (63.5 cm). Water may
intrude into the interior of the vehicle at greater
depths.
Simultaneous Brake And Throttle Operation
Many off-road driving conditions require the simultane-
ous use of the brake and throttle (two footed driving).
When climbing rocks, logs, or other stepped objects,
using light brake pressure with light throttle will keep the
vehicle from jerking or lurching. This technique is also
used when you need to stop and restart a vehicle on a
steep incline.
The Basics Of Off-Road Driving
You will encounter many types of terrain driving off-
road. You should be familiar with the terrain and area
before proceeding. There are many types of surface
