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
c o

nditioning system is turned on, cool
dehumidified 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 radi -
ator), for an accumulation of dirt or insects. C

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
R e

circulation feature may be unavailable (button
on the touchscreen greyed out) if conditions exist
that could create fogging on the inside of the
windshield.

On systems with Manual Climate Controls,
if equipped, the Recirculation mode is not
a l

lowed in Defrost mode to improve window
clearing operation. Recirculation is disabled
automatically if this mode is selected. Attempting to use Recirculation while in this

5. R einstall the protective cover over the
r
emote positive (+) battery post of the
discharged vehicle.
If frequent jump starting is required to start
your vehicle, you should have the battery and
c h

arging system inspected at an authorized
dealer.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase the
e n

gine idle speed while preventing vehicle
motion with the brakes. NOTE:

There are steps that you can take to slow down
an
impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.
CAUTION!

Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices,
etc.). Eventually, if plugged in long enough
without engine operation, the vehicle’s battery
will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.

WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.

SERVICING AND MAINTENANCE 221
CHECKING OIL LEVEL
To ensure proper engine lubrication, the engine
oil must be maintained at the correct level.
Check the oil level at regular intervals, such as
every fuel stop. The best time to check the
engine oil level is about five minutes after a fully
warmed engine is shut off. Checking engine oil
level when the engine is cold will give you an
incorrect reading.
Checking the oil while the vehicle is on level
gr

ound and only when the engine is hot, will
improve the accuracy of the oil level readings.
Maintain the oil level between the range
markings on the dipstick. Either the range
markings consist of a crosshatch zone marked
SAFE or a crosshatch zone marked with MIN at
the low end of the range and MAX at the high
end of the range. Adding 1 Quart (1 Liter) of oil
when the reading is at the low end of the range
marking will raise the oil level to the high end of
the range marking.
ADDING WASHER FLUID
The windshield washer and the rear window
washer share the same fluid reservoir. The fluid
reservoir is located in the engine compartment.
Be sure to check the fluid level in the reservoir
at regular intervals. Fill the reservoir with
windshield washer solvent (not radiator
antifreeze) and operate the system for a few
seconds to flush out the residual water.
When refilling the washer fluid reservoir, apply
s o

me washer fluid to a cloth or towel and wipe
the wiper blades clean. This will help blade
performance.
To prevent freeze-up of your windshield washer
s y

stem in cold weather, select a solution or
mixture that meets or exceeds the temperature
range of your climate. This rating information
can be found on most washer fluid containers. The fluid reservoir will hold nearly 1 Gallon

(4 Liters) of washer fluid when the message
“ Lo

WASH” appears in the instrument cluster.
MAINTENANCE-FREE BATTERY

Your vehicle is equipped with a maintenance-free
battery. You will never have to add water, nor is
periodic maintenance required.

NOTE:
The battery is stored in a compartment that is
lo
cated behind the left front fender and is
accessible through the wheel well. The wheel
and tire assembly do not need to be removed to
access the compartment. Remote battery termi -
nals are located in the engine compartment for
j u

mp starting. Refer to “Jump Starting Proce -
dure” in “In Case Of Emergency” for further
i n

formation.
CAUTION!
Do not overfill the engine with oil. Overfilling
the engine with oil will cause oil aeration,
which can lead to loss of oil pressure and an
increase in oil temperature. This loss of oil
pressure and increased oil temperature could
damage your engine.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.

Refrigerant Recovery And Recycling —
R-1234yf

R-1234yf Air Conditioning Refrigerant is a
hydrofluoroolefin (HFO) that is endorsed by
the Environmental Protection Agency and
is an ozone-friendly substance with a low
g l

obal-warming potential. The manufacturer
recommends that air conditioning service be
performed by an authorized dealer using
recovery and recycling equipment.

NOTE:
Use only manufacturer approved A/C system
P A

G compressor oil, and refrigerants.
ACCESSORY DRIVE BELT INSPECTION
When inspecting accessory drive belts, small
cracks that run across the ribbed surface of the
belt from rib to rib, are considered normal.
These are not a reason to replace the belt.
However, cracks running along a rib (not across)
are not normal. Any belt with cracks running
along a rib must be replaced. Also have the belt
replaced if it has excessive wear, frayed cords
or severe glazing.
Accessory Belt (Serpentine Belt)

Conditions that would require replacement:
Rib chunking (one or more ribs has sepa -
rated from belt body)
Rib or belt wear
Longitudinal belt cracking (cracks between
two ribs)
Belt slips
“Groove jumping" (belt does not maintain
correct position on pulley)
Belt broken (Identify and correct problem
before new belt is installed)
Noise (objectionable squeal, squeak, or
rumble is heard or felt while drive belt is in
operation)
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
Such damage is not covered by the New
Vehicle Limited Warranty.WARNING!
Do not attempt to inspect an accessory
drive belt with vehicle running.
When working near the radiator cooling fan,
disconnect the fan motor lead. The fan is
temperature controlled and can start at any
time regardless of ignition mode. You could
be injured by the moving fan blades.
You can be badly injured working on or
around a motor vehicle. Only do service
work for which you have the knowledge and
the proper equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a compe -
tent mechanic.

228 SERVICING AND MAINTENANCE
(Continued)

Under normal operating conditions, the catalytic
converter will not require maintenance. However,
it is important to keep the engine properly tuned
to ensure proper catalyst operation and prevent
possible catalyst damage.

NOTE:
Intentional tampering with emissions control
s y

stems can result in civil penalties being
assessed against you.

In unusual situations involving grossly
m a

lfunctioning engine operation, a scorching odor
may suggest severe and abnormal catalyst
overheating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, including a
tune-up to manufacturer's specifications, should be
obtained immediately.

To minimize the possibility of catalytic converter
d a

mage:
Do not interrupt the ignition when the trans -
mission is in gear and the vehicle is in
m o

tion.
Do not try to start the vehicle by pushing or
towing the vehicle.
Do not idle the engine with any ignition
components disconnected or removed, such
as when diagnostic testing, or for prolonged
periods during very rough idle or malfunc -
tioning operating conditions.
COOLING SYSTEM
Coolant Checks

Check the engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
w e
ather, where applicable). If the engine coolant
(antifreeze) is dirty or rusty in appearance, the
system should be drained, flushed, and refilled
with fresh engine coolant (antifreeze). Check the
front of the A/C condenser for any accumulation
of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically
down the face of the condenser.

Check the coolant recovery bottle tubing for
b r

ittle rubber, cracking, tears, cuts, and
tightness of the connection at the bottle and
radiator. Inspect the entire system for leaks.
WARNING!

You or others can be badly burned by hot
engine coolant (antifreeze) or steam from your
radiator. If you see or hear steam coming from
under the hood, do not open the hood until the
radiator has had time to cool. Never open a
cooling system pressure cap when the radiator
or coolant bottle is hot.

Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts automati -
cally and may start at any time, whether the
e n

gine is running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the
ignition to the OFF mode. The fan is
temperature controlled and can start at any
time the ignition is in the ON mode.
WARNING!
The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a
safety precaution. Never add engine
coolant (antifreeze) when the engine is
overheated. Do not loosen or remove the
cap to cool an overheated engine. Heat
causes pressure to build up in the cooling
system. To prevent scalding or injury, do not
remove the pressure cap while the system
is hot or under pressure.

SERVICING AND MAINTENANCE 229
Cooling System — Drain, Flush And Refill
NOTE:
Some vehicles require special tools to add
c o

olant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system please contact your local authorized
dealer.
If the engine coolant (antifreeze) is dirty or
c o

ntains visible sediment, have an authorized
dealer clean and flush with OAT coolant
(antifreeze) (conforming to MS.90032).
Refer to the “Maintenance Plan” in (Servicing
a n

d Maintenance” for the proper maintenance
intervals.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
NOTE:

Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technology
(OAT) engine coolant (antifreeze), may result in
engine damage and may decrease corrosion
protection. Organic Additive Technology (OAT)
engine coolant is different and should not be
mixed with Hybrid Organic Additive Technology
(HOAT) engine coolant (antifreeze) or any
“globally compatible” coolant (antifreeze). If a
non-OAT engine coolant (antifreeze) is intro -
duced into the cooling system in an emer-
gency, the cooling system will need to be
d r

ained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032), by an
authorized dealer as soon as possible.

Do not use water alone or alcohol-based
engine coolant (antifreeze) products. Do not
use additional rust inhibitors or antirust prod -
ucts, as they may not be compatible with the
r a

diator engine coolant and may plug the
radiator.
This vehicle has not been designed for use
with propylene glycol-based engine coolant
(antifreeze). Use of propylene glycol-based
engine coolant (antifreeze) is not recom -
mended.
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added
to the system please contact an authorized
dealer.
Adding Coolant

Your vehicle has been built with an improved
engine coolant (OAT coolant conforming to
MS.90032) that allows extended maintenance
intervals. This engine coolant (antifreeze)
can be used up to ten years or 150,000 miles
( 2

40,000 km) before replacement. To prevent
r e

ducing this extended maintenance period, it is
important that you use the same engine coolant
(OAT coolant conforming to MS.90032)
throughout the life of your vehicle.

Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
