Rear Heated Seats — If Equipped
On some models, the two rear outboard seats may
be equipped with heated seats. There are two
heated seat switches that allow the rear
passengers to operate the seats independently.
The heated seat switches for each heater are
located on the rear of the center console. You can choose from HI, LO, or OFF heat settings.
A
m

ber indicator lights in each switch indicate the
level of heat in use. Two indicator lights will
illuminate for HI, one for LO and none for OFF.
Push the heated seat button once to turn the
HI setting on.
Push the heated seat button a second time
to turn the LO setting on.
Push the heated seat button a third time to
turn the heating elements off.
When the HI-level setting is selected, the heater
w i

ll provide a boosted heat level during the first
four minutes of operation. Then, the heat output
will drop to the normal HI-level. If the HI-level
setting is selected, the system will automatically
switch to LO-level after approximately 60 minutes
of

continuous operation. At that time, the number
of indicator lights changes from two to one,
indicating the change. The LO-level setting will turn
off automatically after approximately 45 minutes.
NOTE:
Once a heat setting is selected, heat will be felt
within two to five minutes.
The engine must be running for the heated
seats to operate.
FRONT VENTILATED SEATS —
I
F EQUIPPED
The ventilated seats are equipped with fans that
can be controlled through the climate and control
screen in the Uconnect system. The fans operate
at two speeds, HI and LO.
Press the ventilated seat button once to
choose HI.
Press the ventilated seat button a second
time to choose LO.
Press the ventilated seat button a third time
to turn the ventilated seat off.
WARNING!
Persons who are unable to feel pain to the
skin because of advanced age, chronic illness,
diabetes, spinal cord injury, medication,
alcohol use, exhaustion or other physical
condition must exercise care when using the
seat heater. It may cause burns even at low
temperatures, especially if used for long
periods of time.
Do not place anything on the seat or seatback
that insulates against heat, such as a blanket
or cushion. This may cause the seat heater to
overheat. Sitting in a seat that has been over -
heated could cause serious burns due to the
i n

creased surface temperature of the seat.

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.
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
Ú page 242.
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.

84 STARTING AND OPERATING
AFTER STARTING
The idle speed is controlled automatically, and it
will decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and
permits quicker starts in cold weather. Connect the
cord to a standard 110-115 Volt AC electrical
outlet with a grounded, three-wire extension cord.
The engine block heater must be plugged in at
le

ast one hour to have an adequate warming effect
on the engine.
The engine block heater cord is routed under the
h ood

on the driver side of the vehicle. It has a
removable cap that is located near the air box.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the
drivetrain (engine, transmission, and rear axle) in
your new vehicle.
Drive moderately during the first 300 miles
( 5

00 km). After the initial 60 miles (100 km),
s p
eeds up to 50 or 55 mph (80 or 90 km/h) are
d e
sirable.
While cruising, brief full-throttle acceleration within
th
e limits of local traffic laws contributes to a good
break-in. However, wide-open throttle acceleration
in low gear can be detrimental and should be
avoided.
The engine oil, transmission fluid, and axle
l u

bricant installed at the factory are high-quality
and energy-conserving. Oil, fluid, and lubricant
changes should be consistent with anticipated
climate and conditions under which vehicle
operations will occur. For the recommended
viscosity and quality grades
Ú page 249.
NOTE:
A new engine may consume some oil during its first
f e
w thousand miles (kilometers) of operation. This should be considered a normal part of the break-in
and not interpreted as an indication of difficulty.
Please check your oil level with the engine oil indi
-
cator often during the break in period. Add oil as
r e

quired.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied and place the gear
selector in the PARK position.
The foot operated parking brake is located below
th

e lower left corner of the instrument panel. To
apply the parking brake, firmly push the parking
brake pedal fully. To release the parking brake,
press the parking brake pedal a second time and
let your foot up as you feel the brake disengage.

Parking Brake

CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds before
t r

ying again.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.

178 SAFETY
(Continued)
lug nuts/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
Whenever a change is noticed in the sound of the
ex

haust system, when exhaust fumes can be
detected inside the vehicle, or when the underside
or rear of the vehicle is damaged, have an
authorized dealer inspect the complete exhaust
system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit
exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
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/lift -
gate/rear doors open, make sure that all
w i
ndows 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.
WARNING!
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to prevent
carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in a
closed area, such as a garage, and never sit in
a parked vehicle with the engine running for
an extended period. If the vehicle is stopped in
an open area with the engine running for more
than a short period, adjust the ventilation
system to force fresh, outside air into the
vehicle.
Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.
