GETTING TO KNOW YOUR VEHICLE 71
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 US/Metric customer
programmable feature. Refer to the “Uconnect
Settings” in “Multimedia” for further information.
To provide you with maximum comfort in the
Automatic mode during cold start-ups, the blower
fan remains on low until the engine warms up.
The blower will increase in speed and transition
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
s u

ggested 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 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.

Programming A Non-Rolling Code
For programming garage door openers
manufactured before 1995:

1. P lace the ignition in the ON/RUN position.

N
OTE:
For vehicles equipped with Keyless Enter-N-Go,
p l

ace the ignition in the RUN position with the
engine on. Make sure while programming
HomeLink® with the engine on that your vehicle
is outside of your garage, or that the garage
door remains open at all times.

2. P lace the hand-held transmitter 1 to 3
inches
(3 to 8 cm) away from the HomeLink® button
y o

u wish to program while keeping the
HomeLink® indicator light in view.

3. P ush and hold the HomeLink® button you
w
ant to program while you push and hold
the hand-held transmitter button.
4. C ontinue to hold both buttons and observe
t
he 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. P
ush and hold the programmed
H
omeLink® button and observe the
indicator light.
NOTE:
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.

CANADIAN/GATE OPERATOR
P
ROGRAMMING
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
t r

ansmitter 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
c
y

cling process to prevent possible overheating
of the garage door or gate motor.

1. P lace the ignition in the ON/RUN position.

N
OTE:
For vehicles equipped with Keyless Enter-N-Go,
p l

ace the ignition in the ON/RUN position with
the engine on. Make sure while programming
HomeLink® with the engine on that your vehicle
is outside of your garage, or that the garage
door remains open at all times.
2. P lace the hand-held transmitter 1 to
3
inches (3 to 8 cm) away from the
H o

meLink® button you wish to program
while keeping the HomeLink® indicator
light in view.

3. Continue to push and hold the HomeLink® b
utton 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.

STARTING AND OPERATING 185
Automatic Transmission
The DRIVE range can be selected when towing.
However, if frequent shifting occurs while in
DRIVE, use the AutoStick shift control to
manually select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
u n

der heavy loading conditions will improve
performance and extend transmission life by
reducing excessive shifting and heat build up.
This action will also provide better engine
braking.
If you REGULARLY tow a trailer for more than
4 5

minutes of continuous operation, then
c h

ange the transmission fluid and filter as
specified for “police, taxi, fleet, or frequent
trailer towing”. Refer to the “Scheduled
Servicing” in “Servicing And Maintenance” for
the proper maintenance intervals.
NOTE:
Check the automatic transmission fluid level
b e

fore towing. If you notice fluid leakage or
transmission malfunction, see an authorized
dealer immediately for assistance.
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
( 1

6 km/h), disengage until you can get back
t o

cruising speed.
Use Speed Control in flat terrain and with
light loads to maximize fuel efficiency.
AutoStick
When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent down -
shifts. For example, choose “4” if the desired
s p

eed 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 or vehicle speed when grade and
road conditions allow.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the
tr

ansmission in NEUTRAL, but do not increase
engine idle speed.
Highway Driving
Reduce speed.
Temporarily turn off air conditioning.5

IN CASE OF EMERGENCY 209
Disconnecting The Jumper Cables

1. D isconnect the negative
(-)
jumper cable
from the remote negative (-)
post of the
vehicle with the discharged battery.

2. D isconnect the negative end (
-) of the
jumper cable from the negative (-) post of
the booster battery.
3. D isconnect the opposite end of the
p
ositive (+)
jumper cable from the
positive (+)
post of the booster battery.
4. D isconnect the positive (
+) end of the
jumper cable from the remote positive (+)
post of the discharged vehicle.
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.

IN CASE OF EMERGENCY 211
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 (D) and REVERSE (R) 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)
s
y
stem 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
t h

an 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),
o r

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
t i

res. Do not spin the wheels above 30 mph
( 4

8 km/h) while in gear (no transmission
s h

ifting occurring).

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.

242 SERVICING AND MAINTENANCE
TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Four primary areas are affected by improper tire
pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort and Vehicle Stability Safety
Both underinflation and overinflation affect the
st

ability of the vehicle and can produce a feeling
of sluggish response or over responsiveness in
the steering.
NOTE:
Unequal tire pressures from side to side may
cause erratic and unpredictable steering
response.
Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
r e

sistance resulting in higher fuel consumption.
Tread Wear

Improper cold tire inflation pressures can cause
ab
normal wear patterns and reduced tread life,
resulting in the need for earlier tire replacement.

Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a
c o

mfortable ride. Overinflation produces a
jarring and uncomfortable ride.
WARNING!

Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stopping
distance. Use tires of the recommended load
capacity for your vehicle. Never overload them.
WARNING!
Improperly inflated tires are dangerous and
can cause collisions.
Underinflation increases tire flexing and
can result in overheating and tire failure.
Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that result
in tire failure.
Overinflated or underinflated tires can
affect vehicle handling and can fail
suddenly, resulting in loss of vehicle
control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of the
vehicle to the other can cause the vehicle
to drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
