258IN CASE OF EMERGENCY
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can reduce
the potential for overheating by taking the
appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
NOTE:There are steps that you can take to slow down an
impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off. The
A/C system adds heat to the engine cooling
system and turning the A/C off can help remove
this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the heater
core to act as a supplement to the radiator and
aids in removing heat from the engine cooling
system.
MANUAL PARK RELEASE
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator.
If you see or hear steam coming from under the
hood, do not open the hood until the radiator
has had time to cool. Never try to open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads
HOT (H), pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until
the pointer drops back into the normal range. If
the pointer remains on HOT (H), and you hear
continuous chimes, turn the engine off
immediately and call for service.
WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park
Release. In addition, you should be seated in the
driver’s seat with your foot firmly on the brake
pedal when activating the Manual Park Release.
Activating the Manual Park Release will allow
your vehicle to roll away if it is not secured by the
parking brake, or by proper connection to a tow
vehicle. Activating the Manual Park Release on
an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indicator
system will remind you that it is time to take your
vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent short-trips,
trailer tow, extremely hot or cold ambient
temperatures, and E85 fuel usage will influence
when the “Oil Change Required” message is
displayed. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change.
NOTE:Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Once A Month Or Before A Long Trip:
Check engine oil level
Check windshield washer fluid level
Check the tire pressure and look for unusual
wear or damage
Check the fluid levels of the coolant reservoir,
brake master cylinder and fill as needed
Check function of all interior and exterior lights

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
For best performance and maximum protection
under all types of operating conditions, the
manufacturer only recommends engine oils that
are API Certified and meet the requirements of the
manufacturer Material Standard MS-6395.
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.
CAUTION!
It is essential when replacing the cables on
the battery that the positive cable is attached
to the positive 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.
