54GETTING TO KNOW YOUR VEHICLE
TIP:Voice Command for Climate may only be used to
adjust the interior temperature of your vehicle.
Voice Command will not work to adjust the heated
seats or steering wheel if equipped.
OPERATING TIPS
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
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
performance, 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
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Úpage 292.
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.
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, and if they enter the air distribution
box, they could plug the water drains. In Winter
months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.
Operating Tips Chart
NOTE:The below chart is for Manual Override Operation,
otherwise run in AUTO.
WEATHER CONTROL SETTINGS
Hot Weather And
Vehicle Interior Is Very Hot Set the mode control to
(Panel Mode), (MAX A/C) on, and blower on high. Roll down the windows for a
minute to flush out the hot air. Adjust the controls as
needed to achieve comfort.
Warm Weather Turn (A/C) on and set the
mode control to (Panel Mode).
Cool Sunny Operate in (Bi-Level
Mode).
Cool & Humid Conditions Set the mode control to
(Mix Mode) and turn on
(A/C) to keep windows clear.
Cold Weather Set the mode control to
(Floor Mode). If windshield
fogging starts to occur, move
the control to (Mix Mode).

SAFETY207
(Continued)
Enhanced Accident Response System
In the event of an impact, if the communication
network remains intact, and the power remains
intact, depending on the nature of the event, the
Occupant Restraint Controller (ORC) will determine
whether to have the Enhanced Accident Response
System perform the following functions:
Cut off fuel to the engine (if equipped).
Cut off battery power to the electric motor
(if equipped).
Flash hazard lights as long as the battery has
power.
Turn on the interior lights, which remain on as
long as the battery has power or for 15 minutes
from the intervention of the Enhanced Accident
Response System.
Unlock the power door locks.
Your vehicle may also be designed to perform any
of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the HVAC
Blower Motor, Close the HVAC Circulation Door
Cut off battery power to the:
Engine
Electric Motor (if equipped)
Electric power steering
Brake booster
Electric park brake
Automatic transmission gear selector
Horn
Front wiper
Headlamp washer pump
NOTE:
After an accident, remember to cycle the ignition to
the STOP (OFF/LOCK) position and remove the key
from the ignition switch to avoid draining the battery.
Carefully check the vehicle for fuel leaks in the
engine compartment and on the ground near the
engine compartment and fuel tank before resetting
the system and starting the engine. If there are no
fuel leaks or damage to the vehicle electrical devices
(e.g. headlights) after an accident, reset the system
by following the procedure described below. If you
have any doubt, contact an authorized dealer.
Enhanced Accident Response System
Reset Procedure
In order to reset the Enhanced Accident Response
System functions after an event, the ignition switch
must be changed from ignition START or ON/RUN to
ignition OFF. Carefully check the vehicle for fuel leaks in
the engine compartment and on the ground near the
engine compartment and fuel tank before resetting the
system and starting the engine. After an accident, if the vehicle will not start after
performing the reset procedure, the vehicle must be
towed to an authorized dealer to be inspected and to
have the Enhanced Accident Response System reset.
Maintaining Your Air Bag System
WARNING!
Modifications to any part of the air bag system
could cause it to fail when you need it. You
could be injured if the air bag system is not
there to protect you. Do not modify the compo
-
nents or wiring, including adding any kind of
badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the
instrument panel. Do not modify the front
fascia/bumper, vehicle body structure, or add
aftermarket side steps or running boards.
It is dangerous to try to repair any part of the
air bag system yourself. Be sure to tell anyone
who works on your vehicle that it has an air
bag system.

Materials Added To Engine Oil
The manufacturer strongly recommends against
the addition of any additives (other than leak
detection dyes) to the engine oil. Engine oil is an
engineered product and its performance may be
impaired by supplemental additives.
Disposing Of Used Engine Oil And Oil
Filters
Care should be taken in disposing of used engine oil
and oil filters from your vehicle. Used oil and oil
filters, indiscriminately discarded, can present a
problem to the environment. Contact an authorized
dealer, service station or governmental agency for
advice on how and where used oil and oil filters can
be safely discarded in your area.
ENGINE OIL FILTER
The engine oil filter should be replaced with a new
filter at every engine oil change.
Engine Oil Filter Selection
A full-flow type disposable oil filter should be used
for replacement. The quality of replacement filters
varies considerably. Only high quality Mopar®
certified filters should be used.
ENGINE AIR CLEANER FILTER
For the proper maintenance intervals Úpage 245.
