STARTING AND OPERATING 351
Brake Alert
NOTE:
The “BRAKE!” Screen in the instrument cluster display is a
warning for the driver to take action and does not necessarily
mean that the Forward Collision Warning system is
applying the brakes autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC)
engaged, and following a vehicle, the system will provide an
additional acceleration up to the ACC set speed to assist in passing the vehicle. This additional acceleration is triggered
when the driver utilizes the left turn signal and will only be
active when passing on the left hand side.
ACC Operation At Stop
In the event that the ACC system brings your vehicle to a
standstill while following a target vehicle, if the target
vehicle starts moving within two seconds of your vehicle
coming to a standstill, your vehicle will resume motion
without the need for any driver action.
If the target vehicle does not start moving within two
seconds of your vehicle coming to a standstill, the driver will
either have to push the RES (resume) button, or apply the
accelerator pedal to reengage the ACC to the existing Set
Speed.
NOTE:
After the ACC system holds your vehicle at a standstill for
approximately 3 consecutive minutes, the parking brake will
be activated, and the ACC system will be cancelled.
While ACC is holding your vehicle at a standstill, if the
driver seatbelt is unbuckled or the driver door is opened, the
parking brake will be activated, and the ACC system will be
cancelled.

is set to Normal Ride Height.
4. Using a ballpoint pen or similar object, push and hold the recessed transfer case NEUTRAL (N) button (at the center
of the transfer case switches). The NEUTRAL (N) indi -
cator light will illuminate, and remain lit, when the shift
to NEUTRAL (N) is complete. After the shift is completed
and the NEUTRAL (N) light stays on, release the
NEUTRAL (N) button. 5. Release the parking brake.

Air Conditioner Maintenance
For best possible performance, your air conditioner should

of each warm season. This service should include cleaning of

compartment travel stops are fully engaged.
10. Reattach the glove compartment tension tether byinserting the tether clip in the glove compartment and
sliding the clip away from the face of the glove compart -
ment door.
Accessory Drive Belt Inspection
When inspecting accessory drive belts, small cracks that run
across the ribbed surface of a belt from rib to rib, are consid -
ered normal. These are not a reason to replace the belt.
However, cracks running along a rib (not across) are not
normal. Any belt with cracks running along a rib must be
replaced. Also have the belt replaced if it has excessive wear,
frayed cords or severe glazing.
Accessory Belt (Serpentine Belt)
WARNING!
• Do not attempt to inspect an accessory drive belt with vehicle running.
• When working near the radiator cooling fan, discon -
nect the fan motor lead. The fan is temperature
controlled and can start at any time regardless of igni -
tion mode. You could be injured by the moving fan
blades.
• You can be badly injured working on or around a motor vehicle. Only do service work for which you have the
knowledge and the proper equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.

502 SERVICING AND MAINTENANCE
Conditions that would require replacement:
• Rib chunking (one or more ribs has separated from beltbody)
• Rib or belt wear
• Longitudinal belt cracking (cracks between two ribs)
• Belt slips
• “Groove jumping" (belt does not maintain correct position on pulley)
• Belt broken
• Noise (objectionable squeal, squeak, or rumble is heard or felt while drive belt is in operation)
NOTE:
Identify and correct problem before new belt is installed.
NOTE:
If your vehicle is equipped with Stop/Start belt must be
replaced with an OEM grade Mopar belt.
Some conditions can be caused by a faulty component such
as a belt pulley. Belt pulleys should be carefully inspected for
damage and proper alignment. Belt replacement on some models requires the use of special
tools, we recommend having your vehicle serviced at an
authorized dealer.
Body Lubrication
Locks and all body pivot points, including such items as seat
tracks, door hinge pivot points and rollers, liftgate, tailgate,
decklid, sliding doors and hood hinges, should be lubricated
periodically with a lithium based grease, such as Mopar
Spray White Lube to assure quiet, easy operation and to
protect against rust and wear. Prior to the application of any
lubricant, the parts concerned should be wiped clean to
remove dust and grit; after lubricating excess oil and grease
should be removed. Particular attention should also be given
to hood latching components to ensure proper function.
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 Lubri
-
cant directly into the lock cylinder.

544 SERVICING AND MAINTENANCE
• For grease stains, apply Mopar Multi-Purpose Cleaner to aclean, damp cloth and remove stain. Use a fresh, damp
towel to remove soap residue.
• Do not use any harsh solvents or any other form of protectants on Stain Repel products.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical solvents
or abrasive cleaners. This will weaken the fabric. Sun
damage can also weaken the fabric.
If the belts need cleaning, use a mild soap solution or luke -
warm water. Do not remove the belts from the vehicle to
wash them. Dry with a soft cloth.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
NOTE:
If the belts retract slowly, inspect the upper turning loop for
soiling. If soiling is present, clean with a wet soft cloth until
all residue is removed.
Plastic And Coated Parts
Use Mopar Total Clean to clean vinyl upholstery.
WARNING!
A frayed or torn belt could rip apart in a collision and
leave you with no protection. Inspect the belt system
periodically, checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately. Do not
disassemble or modify the system. Seat belt assemblies
must be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing, etc.).
CAUTION!
• Direct contact of air fresheners, insect repellents, suntan lotions, or hand sanitizers to the plastic,
painted, or decorated surfaces of the interior may cause
permanent damage. Wipe away immediately.
• Damage caused by these type of products may not be covered by your New Vehicle Limited Warranty.
