BRAKE SYSTEM

If power assist is lost for any reason (for example, repeated

brake applications with the engine off), the brakes will still

function. However, you will experience a substantial

increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal

braking capability, the remaining system will still function

with some loss of overall braking effectiveness. This will be

evident by increased pedal travel during application, greater

pedal force required to slow or stop, and activation of the

“Brake Warning Light” and the “ABS Warning Light” (if

equipped) during brake use.
The brake system power assist is provided by a hydro-boost

unit which shares fluid with the power steering system. You

may experience some clicking or hissing noises from the

hydro-boost system during hard braking conditions.
NOTE:

Under cold temperatures, pedal effort will be higher than

normal until the power steering fluid reaches operating

temperature.

Hydraulic Brake Assist

The brake system power assist is provided by a hydro-boost

unit which shares fluid with the power steering system. You

may experience some clicking or hissing noises from the

hydro-boost system during hard braking conditions.
NOTE:

Under cold temperatures, pedal effort will be higher than

normal until the power steering fluid reaches operating

temperature.

WHEEL AND TIRE TORQUE SPECIFICATIONS

Proper lug nut/bolt torque is very important to ensure that

the wheel is properly mounted to the vehicle. Any time a

wheel has been removed and reinstalled on the vehicle, the

lug nuts/bolts should be torqued using a properly calibrated

torque wrench using a high quality six sided (hex) deep wall

socket.

TECHNICAL SPECIFICATIONS

477

Torque Specifications

**Use only your authorized dealer recommended lug nuts/

bolts and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to mounting the

tire and remove any corrosion or loose particles.
NOTE:

Dual wheels are flat mounted, center piloted. The lug nuts

are a two-piece assembly. When the tires are being rotated or

replaced, clean these lug nuts and add two drops of oil at the

interface between the hex and the washer. Ensure that the

socket is fully engaged on the lug nut/bolt (do not insert it

half way).

Oil Interface Location

Do not oil wheel studs. For chrome wheels, do not substitute

with chrome plated wheel nuts.

Wheel Mounting Surface

Retighten the wheel nuts in the same sequence to the torques

listed in the table. Go through the sequence a second time to

verify that specific torque has been achieved. Retighten to

specifications after 25 miles (40 km) and check the lug nut/

bolt torque to be sure that all the lug nuts/bolts are properly

seated against the wheel.

8/10 Lug Nuts/Bolts Torque Patterns

It is recommended that wheel stud nuts be kept torqued to

specifications at all times. Torque wheel stud nuts to specifi-

cations at each lubrication interval.
All wheel nuts should be tightened occasionally to eliminate

the possibility of wheel studs being sheared or the bolt holes

in the wheels becoming elongated. This is especially

important during the first few hundred miles/kilometers of

operation to allow the wheel nuts to become properly set. All

wheel nuts should first be firmly seated against the wheel.

The wheel nuts should then be tightened to recommended

torque. Tighten the wheel nuts to final torque in increments.

Progress around the bolt circle, tightening the wheel nut

opposite to the wheel nut just previously tightened until

final torque is achieved.

FUEL REQUIREMENTS

6.4L Engine

Do not use E-85 flex fuel or ethanol blends greater than 15%

in this engine.

This engines is designed to meet all emissions regu-

lations and provide satisfactory fuel economy and

performance when using high quality unleaded

gasoline having a posted octane number range of 87 to 89 as

specified by the (R+M)/2 method. The use of 89 octane

“Plus” gasoline is recommended for optimum performance

and fuel economy.

While operating on gasoline with an octane number of 87,

hearing a light knocking sound from the engine is not a cause

for concern. However, if the engine is heard making a heavy

knocking sound, see your dealer immediately. Use of gaso-

line with an octane number lower than 87 can cause engine

failure and may void or not be covered by the New Vehicle

Limited Warranty.
Poor quality gasoline can cause problems such as hard

starting, stalling, and hesitations. If you experience these

symptoms, try another brand of gasoline before considering

service for the vehicle.

Reformulated Gasoline

Many areas of the country require the use of cleaner burning

gasoline referred to as “Reformulated Gasoline”. Reformu-

lated gasoline contains oxygenates and are specifically

blended to reduce vehicle emissions and improve air quality.
The use of reformulated gasoline is recommended. Properly

blended reformulated gasoline will provide improved

performance and durability of engine and fuel system

components.

WARNING!

To avoid the risk of forcing the vehicle off the jack, do

not tighten the lug nuts/bolts fully until the vehicle has

been lowered. Failure to follow this warning may result

in personal injury.

480 TECHNICAL SPECIFICATIONS

Materials Added To Fuel

Besides using unleaded gasoline with the proper octane

rating, gasolines that contain detergents, corrosion and

stability additives are recommended. Using gasolines that

have these additives will help improve fuel economy, reduce

emissions, and maintain vehicle performance.

Designated TOP TIER Detergent Gasoline contains a

higher level of detergents to further aide in mini-

mizing engine and fuel system deposits. When avail-

able, the usage of TOP TIER Detergent gasoline is

recommended. Visit

www.toptiergas.com

for a list of TOP

TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents should be

avoided. Many of these materials intended for gum and

varnish removal may contain active solvents or similar

ingredients. These can harm fuel system gasket and

diaphragm materials.

Gasoline/Oxygenate Blends

Some fuel suppliers blend unleaded gasoline with oxygen-

ates such as ethanol.

Problems that result from using gasoline containing more

than 15% ethanol (E-15) or gasoline containing methanol are

not the responsibility of the manufacturer and may void or

not be covered under New Vehicle Limited Warranty.

CAUTION!

DO NOT use E-85, gasoline containing methanol, or

gasoline containing more than 15% ethanol (E-15). Use of

these blends may result in starting and drivability

problems, damage critical fuel system components, cause

emissions to exceed the applicable standard, and/or

cause the Malfunction Indicator Light to illuminate.

Please observe pump labels as they should clearly

communicate if a fuel contains greater than 15% ethanol

(E-15).

TECHNICAL SPECIFICATIONS

481

(Continued)

Do Not Use E-85 In Non-Flex Fuel Vehicles

Non-Flex Fuel Vehicles (FFV) are compatible with gasoline

containing up to 15% ethanol (E-15). Use of gasoline with

higher ethanol content may void the New Vehicle Limited

Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85 fuel,

the engine will have some or all of these symptoms:
• Operate in a lean mode.
• OBD II Malfunction Indicator Light on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.

CNG And LP Fuel System Modifications

Modifications that allow the engine to run on Compressed

Natural Gas (CNG) or Liquid Propane (LP) may result in

damage to the engine, emissions, and fuel system compo-

nents. Problems that result from running CNG or LP are not

the responsibility of the manufacturer and may void or not

be covered under the New Vehicle Limited Warranty.

MMT In Gasoline

Methylcyclopentadienyl Manganese Tricarbonyl (MMT) is a

manganese-containing metallic additive that is blended into

some gasoline to increase octane. Gasoline blended with

MMT provides no performance advantage beyond gasoline

of the same octane number without MMT. Gasoline blended

with MMT reduces spark plug life and reduces emissions

system performance in some vehicles. The manufacturer

recommends that gasoline without MMT be used in your

vehicle. The MMT content of gasoline may not be indicated

on the gasoline pump; therefore, you should ask your gaso-

line retailer whether the gasoline contains MMT. MMT is

prohibited in Federal and California reformulated gasoline.

Fuel System Cautions

CAUTION!

Follow these guidelines to maintain your vehicle’s

performance:
• The use of leaded gasoline is prohibited by Federal

law. Using leaded gasoline can impair engine perfor-

mance and damage the emissions control system.

8

482 TECHNICAL SPECIFICATIONS

NOTE:

Intentional tampering with the emissions control system can

result in civil penalties being assessed against you.

Carbon Monoxide Warnings

• An out-of-tune engine or certain fuel or ignition

malfunctions can cause the catalytic converter to over-

heat. If you notice a pungent burning odor or some

light smoke, your engine may be out of tune or

malfunctioning and may require immediate service.

Contact an authorized dealer for service assistance.

• The use of fuel additives, which are now being sold as

octane enhancers, is not recommended. Most of these

products contain high concentrations of methanol. Fuel

system damage or vehicle performance problems

resulting from the use of such fuels or additives is not

the responsibility of the manufacturer and may void or

not be covered under the New Vehicle Limited

Warranty.

CAUTION! (Continued)

WARNING!

Carbon monoxide (CO) in exhaust gases is deadly.

Follow the precautions below to prevent carbon

monoxide poisoning:
• Do not inhale exhaust gases. They contain carbon

monoxide, a colorless and odorless gas, which can kill.

Never run the engine in a closed area, such as a garage,

and never sit in a parked vehicle with the engine

running for an extended period. If the vehicle is

stopped in an open area with the engine running for

more than a short period, adjust the ventilation system

to force fresh, outside air into the vehicle.

• Guard against carbon monoxide with proper mainte-

nance. Have the exhaust system inspected every time

the vehicle is raised. Have any abnormal conditions

repaired promptly. Until repaired, drive with all side

windows fully open.
