approximately four minutes after the wipers completely
stop. Refer to “Windshield Wipers and Washers” in this
section for further information.
NOTE:When your headlights come on during the
daytime, the instrument panel lights will automatically
dim to the lower nighttime intensity. Refer to “Lights” in
this section for further information.
SmartBeam™ — If Equipped
The SmartBeam™ system provides increased forward
lighting at night by automating high beam control
through the use of a digital camera mounted on the
inside rearview mirror. This camera detects vehicle spe-
cific light and automatically switches from high beams to
low beams until the approaching vehicle is out of view.
NOTE: If the windshield or SmartBeam™ mirror is
replaced, the SmartBeam™ mirror must be re-aimed to
ensure proper performance. See your local authorized
dealer.
To Activate
1. Select “Auto High Beams.” Refer to “Electronic Ve-
hicle Information Center (EVIC)/Customer-
Programmable Features” in “Understanding Your Instru-
ment Panel” for further information.
2. Turn the end of the multifunction lever to the AUTO
headlight position.
3. Push the multifunction lever away from you (toward
front of vehicle) to engage the high beam mode.
NOTE: This system will not activate until the vehicle is
at or above 20 mph (32 km/h).
To Deactivate
1. Pull back on the multifunction lever to manually
deactivate the system (normal operation of low beams).
2. Push back on the multifunction lever once again to
reactivate the system.

Windshield Washer Operation
To use the washer, pull the lever toward you and hold
while spray is desired. If the lever is pulled while in the
delay range, the wiper will operate for several wipe
cycles after the lever is released, and then resume the
intermittent interval previously selected.
If the lever is pulled while in the off position, the wipers
will operate for several wipe cycles, then turn off.
WARNING!
Sudden loss of visibility through the windshield
could lead to an accident. 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.
Mist
Use the Mist feature when weather conditions make
occasional usage of the wipers necessary. Pull down and
release the control lever for a single wiping cycle.

Rain Sensing Wipers — If Equipped
This feature senses moisture on the windshield and
automatically activates the wipers for the driver. The
feature is especially useful for road splash or overspray
from the windshield washers of the vehicle ahead. Rotate
the end of the multifunction lever to one of five settings
to activate this feature.
The sensitivity of the system can be adjusted with the
multifunction lever. Wiper delay position 1 is the least
sensitive, and wiper delay position 5 is the most sensi-
tive. Setting 3 should be used for normal rain conditions.
Settings 1 and 2 can be used if the driver desires less
wiper sensitivity. Settings 4 and 5 can be used if the
driver desires more sensitivity. Place the wiper switch in
the OFF position when not using the system.
NOTE:
•The Rain Sensing feature will not operate when the
wiper switch is in the low or high-speed position.
•The Rain Sensing feature may not function properly when
ice, or dried salt water is present on the windshield.
•Use of Rain-Xor products containing wax or silicone
may reduce Rain Sensing performance.
•A customer programmable feature in the Electronic
Vehicle Information Center (EVIC) allows the Rain
Sensing feature to be turned off. Refer to “Electronic
Vehicle Information Center (EVIC)/Personal Settings
(Customer-Programmable Features)” in “Understand-
ing Your Instrument Panel” for further information.
The Rain Sensing system has protection features for the
wiper blades and arms, and will not operate under the
following conditions:
•Low Ambient Temperature — When the ignition is
first turned ON, the Rain Sensing system will not
operate until the wiper switch is moved, vehicle speed
is greater than 0 mph (0 km/h), or the outside tem-
perature is greater than 32°F (0°C).

the standard intermittent wiper operation.
Service Interval
When this feature is selected, a service interval between
2,000 miles (3 200 km) and 6,000 miles (10 000 km) in
500 miles (800 km) increments may be selected. Pressing
the STEP button when in this display will select distances
between 2,000 miles (3 200 km) and 6,000 miles
(10 000 km) in 500 miles (800 km) increments.
Reset Service Distance (Displays Only if Service
Interval was Changed)
When this feature is selected, the current accumulated
service distance can be reset to the newly selected service
interval. Press and release the FUNCTION SELECT but-
ton until YES (Y) or NO (N) appears.
Easy Entry/Exit Seat (Available with Memory Seat

This feature provides automatic driver seat positioning to
enhance driver mobility when entering and exiting the
vehicle. To make your selection, press and release the
FUNCTION SELECT button until YES (Y) or NO (N)
appears.
NOTE:The seat will return to the memorized seat
location (if Recall Memory with Remote Key Unlock is set
to ON) when the RKE transmitter is used to unlock the

When performing other underhood services, the hood
latch, release mechanism and safety catch should be
cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as MOPAR
Lock Cylinder Lubricant or equivalent directly into the
lock cylinder.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild nonabrasive cleaner. This will remove accumula-
tions of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield. Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies depend-
ing on geographical area and frequency of use. Poor
performance of blades may be present with chattering,
marks, water lines or wet spots. If any condition is
present please proceed to clean wiper blades with humid
cloth removing any debris that may be affecting its
function.
Adding Washer Fluid
On vehicles equipped with a Electronic Vehicle Informa-
tion Center (EVIC), the low washer fluid level will be
indicated. When the sensor detects a low fluid level, the
windshield will light on the vehicle graphic outline and
the “Washer Fluid Low” message will be displayed. Refer
to “Electronic Vehicle Information Center” in “Under-
standing Your Instrument Panel” for further information.
