Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning system.
When the air conditioning system is turned on, cool dehu -
midified air will flow through the outlets into the cabin. For
improved fuel economy, press the A/C button to turn off the
air conditioning and manually adjust the blower and airflow
mode settings. Also, make sure to select only Panel, Bi-Level,
or Floor modes.
NOTE:
• For Manual Climate Controls, if the system is in Mix, Floor
or Defrost Mode, the A/C can be turned off, but the A/C
system shall remain active to prevent fogging of the
windows.
• If fog or mist appears on the windshield or side glass,
select Defrost mode, and increase blower speed if needed.
• 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 accumulation of dirt or insects.
Clean with a gentle water spray from the front of the radi -
ator and through the condenser. 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 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 selected
setting and MAX A/C to exit.
Recirculation
In cold weather, use of Recirculation mode may lead to
excessive window fogging. The Recirculation feature may be
unavailable (button on the touchscreen greyed out) if condi -
tions exist that could create fogging on the inside of the
windshield.
On systems with Manual Climate Controls, if equipped, the
Recirculation mode is not allowed in Defrost mode to
improve window clearing operation. Recirculation is
disabled automatically if this mode is selected. Attempting
to use Recirculation while in this mode causes the LED in the
control button to blink and then turns off.

Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor -
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration of
coolant is used. Use of the Air Recirculation mode during
Winter months is not recommended, because it may cause
window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service (i.e.,
vacation) for two weeks or more, run the air conditioning
system at idle for about five minutes, in fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor
damage when the system is started again. Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select Defrost
or Mix mode and increase the front blower speed. Do not use
the Recirculation mode without A/C for long periods, as
fogging may occur.
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.

WINDOWS
Power Windows
Power Window Controls
Power Window Switches
The power window controls located on the driver's door trim
panel have up-down switches that give you fingertip control of
all power windows. There is a single opening and closing
switch on the front passenger door for passenger window
control and on the rear doors for rear window control. The
windows will operate when the ignition switch is turned to the ON/RUN or ACC position, and for up to 10 minutes after the
ignition is turned OFF or until a front door is opened.
NOTE:
The Key Off Power Delay feature will allow the power
windows to operate for up to 10 minutes after the ignition is
turned OFF. This feature is cancelled when either front door
is opened.
Auto-Down
Both the driver and front passenger window switch have an
Auto-Down feature. Push the window switch past the first
detent, release, and the window will go down automatically. WARNING!
Never leave children unattended in a vehicle. Do not
leave the key fob in or near the vehicle or in a location
accessible to children, and do not leave the ignition of a
vehicle equipped with Keyless Enter-N-Go in the ACC
or ON/RUN mode. Occupants, particularly unattended
children, can become entrapped by the windows while
operating the power window switches. Such entrapment
may result in serious injury or death.

162 SAFETY
ABS is designed to function with the OEM tires. Modification
may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will turn on
when the ignition is turned to the ON/RUN mode and may
stay on for as long as four seconds.
If the “Anti-Lock Brake Warning Light” remains on or comes
on while driving, it indicates that the anti-lock portion of the
brake system is not functioning and that service is required. However, the conventional brake system will continue to
operate normally if the “Anti-Lock Brake Warning Light” is
on.
If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “Anti-Lock Brake Warning
Light” does not come on when the ignition is turned to the
ON/RUN mode, have the light repaired as soon as possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced Electronic Brake
Control system (EBC). This system includes Electronic Brake
Force Distribution (EBD), Anti-Lock Brake System (ABS),
Brake Assist System (BAS), Hill Start Assist (HSA), Traction
Control System (TCS), Electronic Stability Control (ESC),
and Electronic Roll Mitigation (ERM). These systems work
together to enhance both vehicle stability and control in
various driving conditions.
Your vehicle may also be equipped with Trailer Sway
Control (TSC) and Hill Descent Control (HDC).• The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase braking
or steering efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the traction
afforded.
• The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
• The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user’s safety or the safety of
others. WARNING! (Continued)

SAFETY 163
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the braking torque
between the front and rear axles by limiting braking pressure
to the rear axle. This is done to prevent overslip of the rear
wheels to avoid vehicle instability, and to prevent the rear
axle from entering ABS before the front axle.
Brake System Warning Light
The red “Brake System Warning Light” will turn on when
the ignition is turned to the ON/RUN mode and may stay on
for as long as four seconds.
If the “Brake System Warning Light” remains on or comes on
while driving, it indicates that the brake system is not func -
tioning properly and that immediate service is required. If
the “Brake System Warning Light” does not come on when
the ignition is turned to the ON/RUN mode, have the light
repaired as soon as possible. Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking capa -
bility during emergency braking maneuvers. The system
detects an emergency braking situation by sensing the rate
and amount of brake application and then applies optimum
pressure to the brakes. This can help reduce braking
distances. The BAS complements the anti-lock brake system
(ABS). Applying the brakes very quickly results in the best
BAS assistance. To receive the benefit of the system, you
must apply continuous braking pressure during the stop -
ping sequence, (do not “pump” the brakes). Do not reduce
brake pedal pressure unless braking is no longer desired.
Once the brake pedal is released, the BAS is deactivated.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capabilities
of a BAS-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopardize
the user's safety or the safety of others. 4
