Once a heat setting is selected, heat will be felt
within two to five minutes.
If the HI-level setting is selected, the system will
automatically switch to LO-level after approxi -
mately 60 minutes of continuous operation. At
that time, the display will change from HI to LO,
indicating the change. The LO-level setting will
turn off automatically after approximately
45 minutes. Vehicles Equipped With Remote Start
On models that are equipped with remote start,
the heated seats can be programmed to come
on during a remote start.
This feature can be programmed through the
instrument cluster display. Refer to “Instrument
Cluster Display” in “Getting To Know Your

Intermittent Wiper System
Use the intermittent wiper when weather
conditions make a single wiping cycle with a
variable pause between cycles desirable.
Rotate the end of the multifunction lever to the
first detent position, and then turn the end of
the lever to select the desired delay interval.
There are five delay settings, which allow you to
regulate the wipe interval from a minimum of
one cycle every second to a maximum of
approximately 36 seconds between cycles. The
delay intervals will double in duration when the
vehicle speed is 10 mph (16 km/h) or less.
Windshield Washers
To use the windshield washer, push on the end
of the lever to the second detent and hold while
spray is desired. If the lever is pushed while on
the intermittent setting, the wipers will turn on
and operate for several wipe cycles after the
lever is released, and then resume the
intermittent interval previously selected. If the
lever is pushed while the wipers are in the off
position, the wipers will operate several wipe
cycles, then turn off.
Mist Feature
Push the end of the multifunction lever inward
(toward the steering column) to the first detent
and release for a single wiping cycle.
NOTE:
The mist feature does not activate the washer
pump; therefore, no washer fluid will be sprayed
on the windshield. The wash function must be
used in order to spray the windshield with
washer fluid.
Rear Wiper And Washer
Rotating the center ring of the wiper lever to the
first detent activates the rear intermittent
wipers. To activate the washers, rotate the
center ring fully forward and the washers will
spray until the ring is released, and then
resume the intermittent interval.
NOTE:
Rear window wipers function in the intermittent
wiper speed only.
CLIMATE CONTROLS
The Climate Control system allows you to
regulate the temperature, air flow, and direction
of air circulating throughout the vehicle. The
controls are located on the touchscreen (if
equipped) and on the instrument panel below
the radio.
Manual Climate Control Overview
The air conditioning and heating system is
designed to make you comfortable in all types
of weather.

3. When the system is set up for your comfort
level, it is not necessary to change the
settings. You will experience the greatest
efficiency by simply allowing the system to
function automatically.
NOTE:
It is not necessary to move the temperature
settings for cold or hot vehicles. The system
automatically adjusts the temperature,
mode, and blower speed to provide comfort
as quickly as possible.
The temperature can be displayed in U.S. or
Metric units by selecting the U.S./Metric
customer programmable feature. To provide
you with maximum comfort in the Automatic
mode during cold start-ups, the blower fan
will remain on low until the engine warms up.
The blower will increase in speed and transi -
tion into AUTO mode.
Manual Operation Override
This system offers a full complement of manual
override features. The AUTO symbol in the front
ATC display will be turned off when the system
is being used in the manual mode.
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.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for proper coolant selection.
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. Refer to “Fluids And
Lubricants” in “Technical Specifications” for
proper coolant selection. Use of the air Recircu -
lation 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.
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
plenum, they could plug the water drains. In
winter months, make sure the air intake is clear
of ice, slush, and snow.
A/C Air Filter
The climate control system filters out dust and
pollen from the air. Refer to an authorized
dealer for filter replacement instructions.
Operating Tips Chart
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.

3. Push and hold the HomeLink® button you
want to program while you push and hold
the hand-held transmitter button.
4. Continue to hold both buttons and observe the indicator light. The HomeLink®
indicator will flash slowly and then rapidly
after HomeLink® has received the
frequency signal from the hand-held
transmitter. Release both buttons after the
indicator light changes from slow to rapid.
5. Push and hold the programmed HomeLink® button and observe the
indicator light.
If the indicator light stays on constantly,
programming is complete and the garage
door/device should activate when the
HomeLink® button is pushed.
To program the two remaining
HomeLink® buttons, repeat each step
for each remaining button. DO NOT erase
the channels.
Reprogramming A Single HomeLink® Button
(Non-Rolling Code)
To reprogram a channel that has been
previously trained, follow these steps:

1. Place the ignition in the ON/RUN position.

2. Push and hold the desired HomeLink® button until the indicator light begins to
flash after 20 seconds. Do not release the
button.
3. Without releasing the button , proceed with
“Programming A Non-Rolling Code” step two
and follow all remaining steps.
Canadian/Gate Operator Programming
For programming transmitters in
Canada/United States that require the
transmitter signals to “time-out” after several
seconds of transmission:
Canadian radio frequency laws require
transmitter signals to time-out (or quit) after
several seconds of transmission, which may not
be long enough for HomeLink® to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators are
designed to time-out in the same manner. It may be helpful to unplug the device during the
cycling process to prevent possible overheating
of the garage door or gate motor.

1. Place the ignition in the ON/RUN position.

2. Place the hand-held transmitter
1 to 3 inches (3 to 8 cm) away from the
HomeLink® button you wish to program
while keeping the HomeLink® indicator
light in view.
3. Continue to push and hold the HomeLink® button while you push and release (“cycle”)
your hand-held transmitter every two
seconds until HomeLink® has successfully
accepted the frequency signal. The
indicator light will flash slowly and then
rapidly when fully trained.
4. Watch for the HomeLink® indicator to change flash rates. When it changes, it is
programmed. It may take up to 30 seconds
or longer in rare cases. The garage door
may open and close while you are
programming.

SAFETY159
Transporting Pets
Air Bags deploying in the front seat could harm
your pet. An unrestrained pet will be thrown
about and possibly injured, or injure a
passenger during panic braking or in a collision.
Pets should be restrained in the rear seat (if
equipped) in pet harnesses or pet carriers that
are secured by seat belts.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
Exhaust Gas WARNING!
An incorrectly anchored tether strap could
lead to increased head motion and
possible injury to the child. Use only the
anchorage position directly behind the child
seat to secure a child restraint top tether
strap.
If your vehicle is equipped with a split rear
seat, make sure the tether strap does not
slip into the opening between the seat -
backs as you remove slack in the strap.
WARNING!
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
Be sure everyone in your vehicle is in a seat
and using a seat belt properly.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you.
To avoid breathing (CO), follow these safety
tips:
Do not run the engine in a closed garage or
in confined areas any longer than needed
to move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO
NOT use the recirculation mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force outside
air into the vehicle. Set the blower at high
speed.

190STARTING AND OPERATING
Automatic Transmission
The DRIVE range can be selected when towing.
However, if frequent shifting occurs while in
DRIVE, use the Electronic Range Select (ERS)
shift control to manually select a lower gear
range.
NOTE:
Using a lower gear range while operating the
vehicle under heavy loading conditions, will
improve performance and extend transmission
life by reducing excessive shifting and heat
buildup. This action will also provide better
engine braking.
If you REGULARLY tow a trailer for more than
45 minutes of continuous operation, then
change the transmission fluid and filter as
specified for "police, taxi, fleet, or frequent
trailer towing." Refer to the “Maintenance Plan”
for the proper maintenance intervals. Electronic Range Select (ERS)When using the ERS shift control, select the
highest gear that allows for adequate perfor
-
mance and avoids frequent downshifts. For
example, choose “4” if the desired speed can
be maintained. Choose “3” or “2” if needed
to maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid
extended driving at high RPM. Return to a
higher gear range or vehicle speed when
grade and road conditions allow.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Speed Control, if you experi -
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Speed Control in flat terrain and with
light loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase
engine idle speed.
Highway Driving
Reduce speed.
Temporarily turn off air conditioning.

20_RT_OM_EN_USC_t.book Page 190

IN CASE OF EMERGENCY221
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating your
engine 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
engine idle speed. 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.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads “H,” pull over and stop the
vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on the “H” and you hear continuous
chimes, turn the engine off immediately and
call for service.
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.

20_RT_OM_EN_USC_t.book Page 221

IN CASE OF EMERGENCY223
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Then,
shift back and forth between DRIVE and
REVERSE while gently pressing the accelerator.
Use the least amount of accelerator pedal
pressure that will maintain the rocking motion,
without spinning the wheels or racing the
engine. Push the "ESC OFF" switch, to place
the Electronic Stability Control (ESC)
system in "ESC Partial OFF" mode,
before rocking the vehicle. Refer to
“Electronic Brake Control System” in “Safety”
for further information. Once the vehicle has
been freed, push the "ESC OFF" switch again to
restore "ESC ON" mode.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after
every five rocking-motion cycles. This will
minimize overheating and reduce the risk of
transmission failure during prolonged efforts
to free a stuck vehicle.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle
and tires. A tire could explode and injure
someone. Do not spin your vehicle's wheels
faster than 30 mph (48 km/h) or for longer than 30 seconds continuously without
stopping when you are stuck and do not let
anyone near a spinning wheel, no matter
what the speed.
CAUTION!
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drivetrain damage may result.
Revving the engine or spinning the wheels
too fast may lead to transmission over -
heating and failure. It can also damage the
tires. Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission
shifting occurring).
