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. For more
information, see Ú page 401.
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 392.
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.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control system
may automatically adjust airflow to maintain cabin
comfort. Customer settings will be maintained
upon return to an engine running condition.
Windshield Wiper De-Icer — If Equipped
The Windshield Wiper De-Icer is a heating element
located at the base of the windshield.
It operates automatically once the following
conditions are met:
Activation By Front Defrost
The Windshield Wiper De-Icer activates auto -
matically during a cold weather manual start
with full defrost, and when the ambient
temperature is below 33°F (0.6°C) .
CAUTION!
Interior air enters the Rear Automatic
Temperature Control system through an intake
grille, located in the right side trim panel behind
the third row seats. The heater outlets are

Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.) will
degrade the battery even more quickly. Only
use these intermittently and with greater
caution.
After the use of high power draw accessories,
or long periods of the vehicle not being started
(with accessories still plugged in), the vehicle
must be driven a sufficient length of time to
allow the generator to recharge the vehicle's
battery.
CAUTION!
WARNING!
To avoid serious injury or death:
Do not insert any objects into the receptacles.
Do not touch with wet hands.
Close the lid when not in use.

vated by any metallic object making a similar
in-and-out motion under the rear fascia/
bumper, such as cleaning using a metal broom.
The Hands-Free Liftgate will only operate when
the transmission is in PARK.
If anything obstructs the Hands-Free Liftgate
while it is opening or closing, the liftgate will
automatically reverse to the closed/open posi -
tion, provided it meets sufficient resistance.
There are pinch sensors attached to the side of
the liftgate opening. Light pressure anywhere
along these strips will cause the liftgate to
return to the open position.
If the power liftgate encounters multiple
obstructions within the same cycle, the system
will automatically stop. If this occurs, the liftgate
must be operated manually.
The power liftgate will release, but not power
open, in temperatures below −12°F (−24°C).
Be sure to remove any buildup of snow or ice
from the liftgate before opening the liftgate.
If the liftgate is left open for an extended period
of time (approximately one hour), the liftgate
may need to be closed manually to reset power
liftgate functionality. Gas props support the liftgate in the open position.

122STARTING AND OPERATING
4. If the engine fails to start after eight attempts, allow the starter to cool for at least
10 minutes, then repeat the Extended Park
Starting procedure.
IF ENGINE FAILS TO START
If the engine fails to start after you have followed
the “Normal Starting” procedure and has not
experienced an Extended Park condition as
defined previously, it may be flooded. Push the
accelerator pedal all the way to the floor and hold
it there while the engine is cranking. This should
clear any excess fuel in case the engine is flooded.
The starter motor will engage automatically, run for
10 seconds, and then disengage. Once this occurs,
release the accelerator pedal and brake pedal,
wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
COLD WEATHER OPERATION
(B
ELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
AFTER STARTING
The idle speed is controlled automatically, and it
will decrease as the engine warms up.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine
and drivetrain (transmission and axle) in your
vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
Brief full-throttle acceleration within the limits of
local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory
is a high-quality energy conserving type lubricant.
Oil changes should be consistent with anticipated
climate conditions under which vehicle operations
will occur Ú page 338.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a
time. Wait 10 to 15 seconds before trying again.
WARNING!
Never pour fuel or other flammable liquid into
the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto -
matic transmission cannot be started this
way. Unburned fuel could enter the catalytic
converter and once the engine has started,
ignite and damage the converter and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly Ú page 320.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than 10
seconds at a time. Wait 10 to 15 seconds before
trying again.
