Transmitter Battery Replacement
The recommended replacement battery is CR2032.
NOTE:Perchlorate Material – special handling may
apply; See www.dtsc.ca.gov/hazardouswaste/
perchlorate.
1. If the RKE transmitter is equipped with a screw,
remove the screw. With the RKE transmitter buttons
facing down, use a flat blade screwdriver to pry the two
halves of the RKE transmitter apart. Use extreme carenot
to damage the seal or internal components.
2. Remove and replace the battery. Avoid touching the
new battery with your fingers. Skin oils may cause
battery deterioration. If you touch a battery, clean it with
rubbing alcohol.
3. To reassemble the RKE transmitter case, snap the two
halves together.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 23

ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws, contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur. For
the recommended viscosity and quality grades refer to
“Maintenance Procedures” in “Maintaining Your Ve-
hicle”. NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not inter-
preted as an indication of difficulty.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.
WARNING!
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
•It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seri-
ously injured or killed.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 75

Operating Tips
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases
turning on the air-conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield. Adjust the temperature
control and blower speed to maintain comfort. Higher
blower speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by selecting the
defrost mode.Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Fluids and
Genuine Parts in “Maintaining Your Vehicle” for the
proper coolant type.
324 UNDERSTANDING YOUR INSTRUMENT PANEL

Engine Oil Viscosity (SAE Grade)
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” in “Maintaining Your Vehicle” for further informa-
tion.
Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber, should not be used.
Synthetic Engine Oils
Synthetic engine oils can be used if the recommended oil
quality requirements are met, and the recommended
maintenance intervals for oil and filter changes are
followed.
Materials Added to Engine Oils
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental
additives.
Disposing of Used Engine Oil and Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station, or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced with a new filter
at every engine oil change.
462 MAINTAINING YOUR VEHICLE

Engine Oil Filter Selection
All of the manufacturer’s engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high quality filters should be used to assure
most efficient service. MOPARengine oil filters are high
quality oil filters and are recommended.
Engine Air Cleaner Filter
Refer to “Maintenance Schedule” for further information.
WARNING!
The air cleaner can provide protection in the case of
engine backfire. Do not remove the air cleaner unless
it is necessary for repair or maintenance. Make sure
that no one is near the engine compartment before
starting the vehicle with the air cleaner removed.
Failure to do so can result in serious personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
used to assure most efficient service. MOPAR engine air
cleaner filters are a high quality filter and are
recommended.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic main-
tenance required.

MAINTAINING YOUR VEHICLE 463

WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information. 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 labeled on the origi-
nal factory installed hydraulic master cylinder
reservoir.(Continued)
WARNING! (Continued)
•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 a 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 accident.
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.(Continued)

CAUTION!
When replacing the plugs, do not overtighten them.
You could damage them and cause them to leak.
Selection of Lubricant
Use only manufacturer’s recommended fluid. Refer to
“Fluids, Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.
Front/Rear Axle Fluid
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the axle assembly should be
inspected. If gear oil leakage is suspected inspect the
fluid level. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion.
Fluid Level Check
Lubricant should be at the bottom edge of the oil fill hole.
Adding Fluid
Add lubricant only at the fill hole and only to the level
specified above.
Selection of Lubricant
Use only manufacturer’s recommended fluid. Refer to
“Fluids, Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.
Appearance Care and Protection from Corrosion
Protection of Body and Paint from Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and those that are sprayed on
trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
