SERVICING AND MAINTENANCE341
PRESSURE WASHING
Cleaning the engine compartment with a high pressure
washer is not recommended.
VEHICLE MAINTENANCE
An authorized dealer has the qualified service personnel,
special tools, and equipment to perform all service
operations in an expert manner. Service Manuals are
available which include detailed service information for
your vehicle. Refer to these Service Manuals before
attempting any procedure yourself.
NOTE:Intentional tampering with emissions control systems may
void your warranty and could result in civil penalties being
assessed against you.
ENGINE OIL
Engine Oil Selection
Use only the manufacturer's recommended fluids Úpage 396.
NOTE:Hemi engines (5.7L) at times can tick right after startup
and then quiet down after approximately 30 seconds. This
is normal and will not harm the engine. This characteristic
can be caused by short drive cycles. For example, if the
vehicle is started then shut off after driving a short
distance. Upon restarting, you may experience a ticking
sound. Other causes could be if the vehicle is unused for
an extended period of time, incorrect oil, extended oil
changes or extended idling. If the engine continues to tick
or if the Malfunction Indicator Light (MIL) comes on, see
the nearest authorized dealer.
American Petroleum Institute (API)
Approved Engine Oil
These symbols mean that the oil has been certified by the
API. The manufacturer only recommends API trademark
oils.
The API Starburst trademark certifies 0W-20,
0W-30 and 5W-30 engine oils.
The API Donut trademark certifies 0W-40 and
5W-40 engine oil.
CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the posi -
tive post and the negative cable is attached to the
negative post. Battery posts are marked positive (+)
and negative (-) and are identified on the battery
case. Cable clamps should be tight on the terminal
posts and free of corrosion.
 If a “fast charger” is used while the battery is in the
vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery. Do not
use a “fast charger” to provide starting voltage.
CAUTION!
Precautions have been taken to safeguard all parts and
connections however, the pressures generated by these
machines is such that complete protection against
water ingress cannot be guaranteed.
WARNING!
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.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.

Installing The Front Wipers

1. Lift the wiper arm off of the glass, until the wiper arm is in the full up position.

2. Position the wiper blade near the hook on the tip of the wiper arm.
3. Slide the wiper blade up into the hook on the wiper arm, latch engagement will be accompanied by an
audible click.
4. Gently lower the wiper blade onto the glass.
EXHAUST SYSTEM
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete
exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition, have
the exhaust system inspected each time the vehicle is
raised for lubrication or oil change. Replace as required.CAUTION!
Do not allow the wiper arm to spring back against the
glass without the wiper blade in place or the glass may
be damaged.

WARNING!
 Exhaust gases can injure or kill. They contain Carbon
Monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO see
Úpage 311.
 A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your
exhaust system. Do not park or operate your vehicle
in areas where your exhaust system can contact
anything that can burn.

Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilometers
of operation, you may observe vapor coming from the front
of the engine compartment. This is normally a result of
moisture from rain, snow, or high humidity accumulating
on the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze) to enter
the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
Do not overfill the coolant expansion bottle.
 Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant needs
to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
 If frequent engine coolant additions are required, the
cooling system should be pressure tested for leaks.
 Maintain engine coolant concentration at a minimum
of 50% OAT coolant (conforming to MS.90032) and
distilled water for proper corrosion protection of your
engine which contains aluminum components.
 Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed. 
Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
 Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine cooling performance,
poor gas mileage, and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all brake
system components should be inspected periodically
Úpage 334.
Fluid Level Check — Brake Master Cylinder
The fluid level of the brake master cylinder should be
checked whenever the vehicle is serviced, or immediately
if the Brake System Warning Light is on. If necessary, add
fluid to bring level within the designated marks on the side
of the reservoir of the brake master cylinder. Be sure to
clean the top of the master cylinder area before removing
cap. With disc brakes, fluid level can be expected to fall as
the brake pads wear. Brake fluid level should be checked
when pads are replaced. If the brake fluid is abnormally
low, check the system for leaks
Úpage 397.
WARNING!
Riding the brakes can lead to brake failure and possibly
a collision. Driving with your foot resting or riding on the
brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible brake
damage. You would not have your full braking capacity
in an emergency.
WARNING!
Use only manufacturer's recommended brake fluid Úpage 397. Using the wrong type of brake fluid can
severely damage your brake system and/or impair its
performance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
 To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in an open container absorbs moisture from the
air resulting in a lower boiling point. This may cause
it to boil unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This could
result in a collision.

WARNING: Operating, servicing and maintaining a passenger vehicle or off-highway motor
vehicle can expose you to chemicals including engine exhaust, carbon monoxide, phthalates, and
lead, which are known to the State of California to cause cancer and birth defects or other reproductive
harm. To minimize exposure, avoid breathing exhaust, do not idle the engine except as necessary,
service your vehicle in a well-ventilated area and wear gloves or wash your hands frequently when
servicing your vehicle. For more information go to www.P65Warnings.ca.gov/passenger-vehicle.
