service CHRYSLER 300 LX 2007 Workshop Manual

All Wheel Drive (AWD) — If Equipped
The all wheel drive system consists of a Transfer Case
and Front Differential. The exterior surface of these
components should be inspected for evidence of fluid
leaks. Confirmed leaks should be repaired as soon as
possible.
The transfer case fluid inspection plug is located in the
middle of the rear housing. To inspect the transfer case
fluid level, remove the inspection plug. The fluid level
should be even with the bottom of the hole. The transfer
case fill plug is located on the rear housing near the
output shaft.
The front differential fill plug is located on the outer
cover near the halfshaft attachment. To inspect the differ-
ential fluid level, remove the fill plug. The fluid level
should be even with or slightly below the bottom of the
hole.
Fluid Changes
The fluid should be changed as follows:
Normal Usage
Front Differential No Service RequiredTransfer Case Refer to Maintenance
Schedule “A”
Severe Usage
Front Differential No Service Required
Transfer Case Refer to Maintenance
Schedule “B”
Severe Usage is defined as:
1. More than 50% of vehicle operation in stop and go
traffic where vehicle is driven regularly for more than 45
minutes of continuous operation, such as in heavy city or
in construction zone traffic.
2. Police, taxi, limousine, commercial type operation, or
trailer towing where the vehicle driven regularly for
more than 45 minutes of continuous operation.
Front and Rear Wheel Bearings

CAUTION!
•When installing the Power Distribution Center
cover, it is important to ensure the cover is prop-
erly positioned and fully latched. Failure to do so
may allow water to get into the Power Distribu-
tion Center, and possibly result in an electrical
system failure.
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage
rating. The use of a fuse with a rating other than
indicated may result in a dangerous electrical
system overload. If a properly rated fuse contin-
ues to blow, it indicates a problem in the circuit
that must be corrected.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days, you may want to take steps to protect your battery.
You may:
•Disconnect the negative cable from the battery.
•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
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.

CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with an oily surface, clean the
bulb with rubbing alcohol.
Low Beam Headlight, High Beam Headlight, and
Park/Turn Light – 300C
High Intensity Discharge Headlights (HID) — If
Equipped
The headlights are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlight switch off and the key removed.Because of
this, you should not attempt to service a headlight bulb
yourself. If a headlight bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high tension occurs at the bulb sockets of
High Intensity Discharge (HID) headlights when the
headlight switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.
NOTE:On vehicles equipped with High Intensity Dis-
charge Headlights (HID), when the headlights are turned
on, there is a blue hue to the lights. This diminishes and
becomes more white after approximately 10 seconds, as
the system charges.
1. Open the hood.
NOTE:Removal of the air cleaner filter housing may be
necessary prior to replacing bulbs in the headlight assem-
bly on the driver side of the vehicle.
2. Twist the appropriate bulb and socket assembly
counter-clockwise, and then pull it out of the headlight
assembly.
3. Pull the bulb out of the socket assembly.
