2012 JEEP GRAND CHEROKEE warning light

•Anytime you store your vehicle, or keep it out
of service (i.e. vacation) for two weeks or
more, run the air conditioning system at idle
for about five minutes in the fresh air and
high blower setting. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.

WARNING!
A transient high voltage occurs at the bulb
sockets of High Intensity Discharge (HID)
headlamps when the headlamp switch is
turned ON. It may cause serious electrical
shock or electrocution if not serviced properly.
See your authorized dealer for service. NOTE:
Numbers refer to commercial bulb types
that can be purchased from your authorized
dealer.
If a bulb needs to be replaced, visit your
authorized dealer or refer to the applicable
Service Manual.
BULB REPLACEMENT
High Intensity Discharge Headlamps
(HID) – If Equipped
The headlamps are a type of high voltage
discharge tube. High voltage can remain in the
circuit even with the headlamp switch off and
the key removed.
Because of this, you should
not attempt to service a headlamp bulb your-
self. If a headlamp bulb fails, take your
vehicle to an authorized dealer for service.

† This maintenance is recommended by the
manufacturer to the owner, but is not required
to maintain emissions warranty.
WARNING!
You can be badly injured working on or around
a motor vehicle. Do only that service work for
which you have the knowledge and the right
equipment. If you have any doubt about your
ability to perform a service job, take your
vehicle to a competent mechanic.
Maintenance Schedule – Diesel
Engine
To help you have the best driving experience
possible, the manufacturer has identified the
specific vehicle maintenance service intervals
that are required to keep your vehicle operating
properly and safely.
The manufacturer recommends that these
maintenance intervals be performed at your
selling dealer. The technicians at your dealer-
ship know your vehicle best, and have access
to factory trained information, genuine
MOPARparts, and specially designed elec- tronic and mechanical tools that can help pre-
vent future costly repairs.
The maintenance intervals shown should be
performed as indicated in this section.
NOTE:
Under no circumstances should oil change
intervals exceed 12,500 miles (20 000 km) or
12 months, whichever comes first.
At Each Stop for Fuel
•
Check the engine oil level about 15 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
Once a Month
• Check tire pressure and look for unusual
wear or damage.
• Inspect the battery and clean and tighten the
terminals as required. •
Check the fluid levels of the coolant reser-
voir, brake master cylinder, and power steer-
ing and add as needed.
• Check all lights and other electrical items for
correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
• Inspect for the presence of water in the fuel
filter/water separator unit.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.

Refer to the Maintenance Schedules on the
following pages for the required maintenance
intervals.
