GETTING TO KNOW YOUR VEHICLE63
NOTE:If the vehicle is moving less than 10 mph (16 km/h), delay
times will be doubled.
Windshield Washer Operation
To use the washer, pull the lever rearward toward you and
hold. If the lever is pulled 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
pulled while the wipers are in the off position, the wipers
will operate several cycles, then turn off.
NOTE:
As a protective measure, the pump will stop if the
switch is held for more than 20 seconds. Once the
switch is released the pump will resume normal
operation.
 If the front window washer feature is activated, all of
the front cameras (if equipped) on the vehicle will be
washed as well.
Mist
Use the Mist feature when weather conditions make
occasional usage of the wipers necessary. Push the lever
upward to the MIST position 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 wind -
shield. The washer function must be used in order to spray
the windshield with washer fluid.
For information on wiper care and replacement, see
Úpage 324.
RAIN SENSING WIPERS — IF EQUIPPED
This feature senses rain or snowfall on the windshield and
automatically activates the wipers. Rotate the end of the
windshield wiper lever to one of the four detent positions
to activate this feature.
The sensitivity of the system is adjustable from the
windshield wiper lever. Wiper sensitivity position 1 is the
least sensitive, and wiper sensitivity position 4 is the most
sensitive.
NOTE:
 The Rain Sensing feature will not operate when the
wiper switch is in the low or high position.
 The Rain Sensing feature may not function properly
when ice or dried saltwater is present on the wind -
shield.
 Use of products containing wax or silicone may reduce
rain sensor performance. 
The Rain Sensing feature can be turned on and off
through the Uconnect system
Úpage 197.
The Rain Sensing system has protective features for the
wiper blades and arms. It will not operate under the
following conditions:
 Low Temperature Wipe Inhibit — The Rain Sensing
feature will not operate when the ignition is first placed
in the ON position, when the vehicle is stationary and
the outside temperature is below 32°F (0°C), unless
the wiper control on the windshield wiper lever is
moved, the vehicle speed becomes greater than 3 mph
(5 km/h) or the outside temperature rises above
freezing.
 Neutral Wipe Inhibit — The Rain Sensing feature will not
operate when the ignition is ON, when the transmission
gear selector is in the NEUTRAL position and the
vehicle speed is less than 3 mph (5 km/h), unless the
wiper control on the windshield wiper lever is moved,
the vehicle speed is greater than 3 mph (5 km/h) or
the gear selector is moved out of the NEUTRAL posi -
tion.
 Remote Start Mode Inhibit — On vehicles equipped with
the Remote Start system, Rain Sensing wipers are not
operational when the vehicle is in the Remote Start
mode. Once the operator is in the vehicle and has
placed the ignition switch in the ON/RUN position, rain
sensing wiper operation can resume, if it has been
selected, and no other inhibit conditions
(mentioned previously) exist.
WARNING!
Sudden loss of visibility through the windshield could
lead to a collision. You might not see other vehicles or
other obstacles. To avoid sudden icing of the windshield
during freezing weather, warm the windshield with the
defroster before and during windshield washer use.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and extended idling will influence
when the “Oil Change Required” message is displayed.
Have your vehicle serviced as soon as possible, within the
next 500 miles (805 km).An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change or for
engine oil life reset procedure Úpage 101.
NOTE:3.0L & 5.7L Engines:
Under no circumstances should oil
change intervals exceed 10,000 miles (16,000 km), or
12 months, whichever comes first. The engine controller
also monitors the number of hours of engine run time, and
will illuminate the oil change indicator after 350 hours
(which is not likely to be exceeded except for certain fleet
customers with extended engine idling periods).
6.4L Engines: Under no circumstances should oil change
intervals exceed 6,000 miles (10,000 km), or 6 months,
whichever comes first. The engine controller also monitors
the number of hours of engine run time, and will illuminate
the oil change indicator after 350 hours (which is not likely
to be exceeded except for certain fleet customers with
extended engine idling periods). Once A Month Or Before A Long Trip:

Check engine oil level
 Check windshield washer fluid level
 Check the tire inflation pressures and look for unusual
wear or damage
 Check the fluid levels of the coolant reservoir, brake
master cylinder and fill as needed.
 Check function of all interior and exterior lights

316SERVICING AND MAINTENANCE
CHECKING OIL LEVEL — 3.0L ENGINES
The 3.0L engine does not have a traditional “dipstick” and
there is no need to manually check the oil level. If it is
desired to check engine oil level, it can be seen on the
instrument cluster display by navigating to the appropriate
screen under “Vehicle Information”. Use the up or
down arrow buttons within the steering wheel controls
to find the “Vehicle Information” menu. Then use the
right or left arrow buttons until you reach the “Oil
Level” sub-menu.
There is a white bar on the gauge which shows the oil level.
As long as the oil level is between the minimum and the
maximum it is safe to operate the vehicle. If the oil level is
either too high or too low, a red bar will be illuminated.
When the engine is in need of more oil, the Oil Level
Warning Light will illuminate. This warning will appear for
five seconds. Within the next 300 miles (500 km) you
should add 1 quart of manufacturer specified motor oil to
the engine
Úpage 376. This light will reappear every time the engine is started
until a safe level is detected. Continuing to operate the
vehicle without adding oil may result in a critically low oil
level and possible engine damage (see “Critically Low”
below).
NOTE:Use care when filling under hood fluids such as engine oil,
washer fluid, antifreeze, etc. to minimize spillage onto top
of engine. Any excess fluid that is spilled onto the top of
the engine should be removed using compressed air or an
absorbent cloth.
Oil Level Display - How To Refresh After Adding Oil
In vehicles equipped with the 3.0L engine, the oil level is
automatically monitored when the vehicle is parked on a
level surface, the oil is warm, and the engine has been off
four minutes. To refresh the oil level display (after a quart
of the correct oil has been added), follow this process:

Run the engine until the oil temperature is above
120°F (49°C).
 Park the vehicle on relatively level ground. 
Turn the engine off and wait four minutes. If you choose
to stay in the vehicle and want to listen to the radio
while waiting, it is acceptable to have the ignition
switch in any position (OFF or ON/RUN) as long as the
engine is not running.
 Start the engine and the new oil level will be available
in the Vehicle Information menu (accessible via the
navigation buttons on the steering wheel).
NOTE:
If the level indication is not updated after the previously
described procedure, repeat. The oil level measure -
ment is made every time the engine has been turned
off (after being warmed up) and on a level surface. If
you do not get a “new” reading after adding oil, find a
more “level” surface to measure. Most parking lots and
gas stations are sufficiently level, some driveways are
not.
 If you have added a quart of oil and the indicator is not
reading 3/4 or full, please contact an authorized dealer
for service.
