Wiper Service Position

If it is necessary to lift the blade from the windshield (In the

event of snow or blade replacement) Proceed as directed:
1. Rotate the end of the multifunction lever to the OFF posi

-

tion.

2. Turn the ignition to the MAR-ON position then to STOP.
3. After turning the ignition to the STOP, within two

minutes move the right stalk upward, into the unstable

(“anti-panic”) position, for at least half of a second. The

windshield wiper then executes part of a stroke; at each

command, approximately 1/3 of a normal wiper stroke is

triggered.

NOTE:

The previous operation can be repeated up to three times. In

order to move the blades to the most suitable position.
4. Lift the blade from the windshield and proceed with the

required operation.

5. Carefully lower the blade, bringing it back in contact with

the windshield.

6. Bring the blade to the initial rest position, turning the

ignition to MAR-ON.

NOTE:

Do not operate the wiper with the blades lifted from the

windshield.

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, dete

-

riorated, 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 lubrica

-

tion or oil change. Replace as required.

(Continued)

Under normal operating conditions, the catalytic converter

will not require maintenance. However, it is important to

keep the engine properly tuned to ensure proper catalyst

operation and prevent possible catalyst damage.

NOTE:

Intentional tampering with emissions control systems can

result in civil penalties being assessed against you.
In unusual situations involving grossly malfunctioning

engine operation, a scorching odor may suggest severe and

abnormal catalyst overheating. If this occurs, stop the

vehicle, turn off the engine and allow it to cool. Service,

including a tune-up to manufacturer's specifications, should

be obtained immediately.

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 eventu

-

ally poison you. To avoid breathing CO, refer to “Safety

Tips” in “Safety” for further information.

• 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.

CAUTION!

• The catalytic converter requires the use of unleaded

fuel only. Leaded gasoline will destroy the effective

-

ness of the catalyst as an emissions control device and

may seriously reduce engine performance and cause

serious damage to the engine.

• Damage to the catalytic converter can result if your

vehicle is not kept in proper operating condition. In the

event of engine malfunction, particularly involving

engine misfire or other apparent loss of performance,

have your vehicle serviced promptly. Continued opera

-

tion of your vehicle with a severe malfunction could

cause the converter to overheat, resulting in possible

damage to the converter and vehicle.

CAUTION!

SERVICING AND MAINTENANCE

255

(Continued)

To minimize the possibility of catalytic converter damage:
• Do not interrupt the ignition when the transmission is in

gear and the vehicle is in motion.

• Do not try to start the vehicle by pushing or towing the

vehicle.

• Do not idle the engine with any ignition components

disconnected or removed, such as when diagnostic testing,

or for prolonged periods during very rough idle or

malfunctioning operating conditions.

Cooling System

Engine Coolant Checks

Check the engine coolant (antifreeze) protection every

12 months (before the onset of freezing weather, where

applicable). If the engine coolant (antifreeze) is dirty, the

system should be drained, flushed, and refilled with fresh

OAT coolant (conforming to MS.90032) by an authorized

dealer. Check the front of the A/C condenser for any accu

-

mulation of bugs, leaves, etc. If dirty, clean by gently

spraying water from a garden hose vertically down the face

of the condenser.
Check the engine cooling system hoses for brittle rubber,

cracking, tears, cuts, and tightness of the connection at the

coolant recovery bottle and radiator. Inspect the entire

system for leaks. DO NOT REMOVE THE COOLANT PRES

-

SURE CAP WHEN THE COOLING SYSTEM IS HOT.

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 open a cooling system pressure cap when the

radiator or coolant bottle is hot.

• Keep hands, tools, clothing, and jewelry away from the

radiator cooling fan when the hood is raised. The fan

starts automatically and may start at any time, whether

the engine is running or not.

• When working near the radiator cooling fan, discon

-

nect the fan motor lead or turn the ignition to the OFF

mode. The fan is temperature controlled and can start at

any time the ignition is in the ON mode.

Cooling System — Drain, Flush And Refill

NOTE:

Some vehicles require special tools to add coolant properly.

Failure to fill these systems properly could lead to severe

internal engine damage. If any coolant is needed to be added

to the system please contact an authorized dealer.
If the engine coolant (antifreeze) is dirty or contains visible

sediment, have an authorized dealer clean and flush with

OAT coolant (antifreeze) (conforming to MS.90032).
Refer to the “Maintenance Plan” in this section for the proper

maintenance intervals.

Selection Of Coolant

Refer to “Fluids And Lubricants” in “Technical Specifica

-

tions” for further information.

NOTE:

• Mixing of engine coolant (antifreeze) other than specified

Organic Additive Technology (OAT) engine coolant (anti

-

freeze), may result in engine damage and may decrease

corrosion protection. Organic Additive Technology (OAT)

engine coolant is different and should not be mixed with

Hybrid Organic Additive Technology (HOAT) engine

coolant (antifreeze) or any “globally compatible” coolant

(antifreeze). If a non-OAT engine coolant (antifreeze) is

introduced into the cooling system in an emergency, the

cooling system will need to be drained, flushed, and

refilled with fresh OAT coolant (conforming to MS.90032),

by an authorized dealer as soon as possible.

• Do not use water alone or alcohol-based engine coolant

(antifreeze) products. Do not use additional rust inhibitors

or antirust products, as they may not be compatible with

the radiator engine coolant and may plug the radiator.

• This vehicle has not been designed for use with propylene

glycol-based engine coolant (antifreeze). Use of propylene

glycolbased engine coolant (antifreeze) is not recom

-

mended.

• Some vehicles require special tools to add coolant prop

-

erly. Failure to fill these systems properly could lead to

severe internal engine damage. If any coolant is needed to

be added to the system please contact an authorized

dealer.

Adding Coolant

Your vehicle has been built with an improved engine coolant

(OAT coolant conforming to MS.90032) that allows extended

maintenance intervals. This engine coolant (antifreeze) can

be used up to 10 years or 150,000 miles (240,000 km) before

replacement. To prevent reducing this extended

SERVICING AND MAINTENANCE

257

maintenance period, it is important that you use the same

engine coolant (OAT coolant conforming to MS.90032)

throughout the life of your vehicle.
Please review these recommendations for using Organic

Additive Technology (OAT) engine coolant (antifreeze) that

meets the requirements of FCA Material Standard MS.90032.

When adding engine coolant (antifreeze):
• We recommend using Mopar Antifreeze/Coolant 10

Year/150,000 Mile (240,000 km) Formula OAT (Organic

Additive Technology) that meets the requirements of FCA

Material Standard MS.90032.

• Mix a minimum solution of 50% OAT engine coolant that

meets the requirements of FCA Material Standard

MS.90032 and distilled water. Use higher concentrations

(not to exceed 70%) if temperatures below −34°F (−37°C)

are anticipated. Please contact an authorized dealer for

assistance.

• Use only high purity water such as distilled or deionized

water when mixing the water/engine coolant (antifreeze)

solution. The use of lower quality water will reduce the

amount of corrosion protection in the engine cooling

system.

NOTE:

• It is the owner's responsibility to maintain the proper level

of protection against freezing according to the tempera

-

tures occurring in the area where the vehicle is operated.

• Some vehicles require special tools to add coolant prop

-

erly. Failure to fill these systems properly could lead to

severe internal engine damage. If any coolant is needed to

be added to the system, please contact a local authorized

dealer.

• Mixing engine coolant (antifreeze) types is not recom

-

mended and can result in cooling system damage. If

HOAT and OAT coolant are mixed in an emergency, have

a authorized dealer drain, flush, and refill with OAT

coolant (conforming to MS.90032) as soon as possible.

Cooling System Pressure Cap

The cap must be fully tightened to prevent loss of engine coolant

(antifreeze), and to ensure that engine coolant (antifreeze) will

return to the radiator from the coolant recovery tank.
The cap should be inspected and cleaned if there is any

accumulation of foreign material on the sealing surfaces.

7

258 SERVICING AND MAINTENANCE

The image on the coolant system pressure cap is a

reminder that the radiator contains hot engine

coolant under pressure.

Disposal Of Used Coolant

Used ethylene glycol-based coolant (antifreeze) is a regu

-

lated substance requiring proper disposal. Check with your

local authorities to determine the disposal rules for your

community. To prevent ingestion by animals or children, do

not store ethylene glycol-based coolant in open containers or

allow it to remain in puddles on the ground. If ingested by a

child or pet, seek emergency assistance immediately. Clean

up any ground spills immediately.

Coolant Level

The coolant expansion bottle provides a quick visual method

for determining that the coolant level is adequate. With the

engine OFF and cold, the level of the engine coolant (anti

-

freeze) in the bottle should be between the “MIN” and

“MAX” marks.
The radiator normally remains completely full, so there is no

need to remove the radiator/coolant pressure cap unless

checking for engine coolant (antifreeze) freeze point or

replacing coolant. Advise your service attendant of this. As

long as the engine operating temperature is satisfactory, the

coolant bottle need only be checked once a month.
When additional engine coolant (antifreeze) is needed to

maintain the proper level, only OAT coolant that meets the

requirements of FCA Material Standard MS.90032 should be

added to the coolant bottle. Do not overfill.

WARNING!

• Do not open hot engine cooling system. Never add

engine coolant (antifreeze) when the engine is over

-

heated. Do not loosen or remove the cap to cool an over

-

heated engine. Heat causes pressure to build up in the

cooling system. To prevent scalding or injury, do not

remove the pressure cap while the system is hot or

under pressure.

• Do not use a pressure cap other than the one specified

for your vehicle. Personal injury or engine damage may

result.

SERVICING AND MAINTENANCE

259

Points To Remember

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 mois

-

ture 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 (antifreeze)

needs to be added, the contents of the coolant expansion

bottle must also be protected against freezing.

• If frequent engine coolant (antifreeze) additions are

required, the cooling system should be pressure tested for

leaks.

• Maintain engine coolant (antifreeze) 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 oper

-

ation. If replacement is ever necessary, install ONLY the

correct type thermostat. Other designs may result in unsat

-

isfactory engine coolant (antifreeze) performance, poor

gas mileage, and increased emissions.

Brake System

In order to ensure brake system performance, all brake

system components should be inspected periodically. Refer

to the “Maintenance Plan” in this section for the proper

maintenance intervals.

Brake Master Cylinder

The fluid in the master cylinder should be checked when

performing under hood services or immediately if the

“Brake Warning Light” is illuminated.
Be sure to clean the top of the master cylinder area before

removing the cap. If necessary, add fluid to bring the fluid

level up to the requirements described on the brake fluid

reservoir. 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. However, low fluid level may be

caused by a leak and a checkup may be needed.
Use only manufacturer's recommended brake fluid. Refer to

“Fluids And Lubricants” in “Technical Specifications” for

further information.

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.

Refer to “Fluids And Lubricants” in “Technical Speci

-

fications” 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 identified on the

original factory installed hydraulic master cylinder

reservoir.

• To avoid contamination from foreign matter or mois

-

ture, 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 unexpect

-

edly during hard or prolonged braking, resulting in

sudden brake failure. This could result in a collision.

SERVICING AND MAINTENANCE

261

Power Steering Fluid

Check the fluid level with the vehicle on flat ground and

engine cold. Fluid should be between MIN and MAX refer

-

ences on the reservoir body.
The level may go over the MAX line when oil is hot.
If topping off is required, make sure the oil you use is

approved. Refer to “Fluids And Lubricants” in “Technical

Specifications” for further information.

NOTE:

Power steering fluid consumption is very low. If you need to

top off your fluid often and multiple times, have your system

inspected by an authorized dealer.

Automatic Transmission

Selection Of Lubricant

It is important to use the proper transmission fluid to ensure

optimum transmission performance and life. Use only the

manufacturer's specified transmission fluid. Refer to “Fluids

And Lubricants” in “Technical Specifications” for fluid spec

-

ifications. It is important to maintain the transmission fluid

at the correct level using the recommended fluid.

NOTE:

No chemical flushes should be used in any transmission;

only the approved lubricant should be used.

• 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.

• Do not allow petroleum based fluid to contaminate the

brake fluid. Brake seal components could be damaged,

causing partial or complete brake failure. This could

result in a collision.

WARNING!

262 SERVICING AND MAINTENANCE

Special Additives

The manufacturer strongly recommends against using any

special additives in the transmission. Automatic Transmis

-

sion Fluid (ATF) is an engineered product and its perfor

-

mance may be impaired by supplemental additives.

Therefore, do not add any fluid additives to the transmis

-

sion. Avoid using transmission sealers as they may

adversely affect seals.

Fluid Level Check

The fluid level is preset at the factory and does not require

adjustment under normal operating conditions. Routine

fluid level checks are not required; therefore the transmis

-

sion has no dipstick. An authorized dealer can check your

transmission fluid level using special service tools. If you

notice fluid leakage or transmission malfunction, visit an

authorized dealer immediately to have the transmission

fluid level checked. Operating the vehicle with an improper

fluid level can cause severe transmission damage.

CAUTION!

Using a transmission fluid other than the manufacturer’s

recommended fluid may cause deterioration in

transmission shift quality and/or torque converter

shudder. Refer to “Fluids And Lubricants” in “Technical

Specifications” for fluid specifications.

CAUTION!

Do not use chemical flushes in your transmission as the

chemicals can damage your transmission components.

Such damage is not covered by the New Vehicle Limited

Warranty.

CAUTION!

If a transmission fluid leak occurs, visit an authorized

dealer immediately. Severe transmission damage may

occur. An authorized dealer has the proper tools to adjust

the fluid level accurately.
