Clutch Hydraulic System — Manual Transmission
(If Equipped)
The clutch hydraulic system is fed by a segregated volume
of fluid within the brake system master cylinder reservoir.
In the event of leakage or wear, use only the manufactur-
er’s recommended brake fluid. Refer to “Fluids And Lu-
bricants” in “Technical Specifications” for further informa-
tion.
Manual Transmission — If Equipped
Fluid Level Check
Check the fluid level by removing the fill plug on the left
side of the transmission. The fluid level should be 1/4 inch
(6.4mm) below the bottom of the fill hole. Add fluid, if
necessary, to maintain the proper level. Refer to “Fluids
And Lubricants” in “Technical Specifications” for further
information.
CAUTION!
Using a transmission fluid other than the manufactur-
er’s recommended fluid may cause deterioration in

transmission shift quality and/or damage to the trans-
mission. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
Change Transmission Fluid
If contaminated with water, change the fluid immediately.
See your authorized dealer for service.
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
Automatic Transmission — If Equipped
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 specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.
NOTE:No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.

SERVICING AND MAINTENANCE 355

CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
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. There-
fore, do not add any fluid additives to the transmission.
Avoid using transmission sealers as they may adversely
affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
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 im-
proper fluid level can cause severe transmission damage.
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.
Fluid And Filter Changes
Under normal operating conditions, the fluid installed at
the factory will provide satisfactory lubrication for the life
of the vehicle.

WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts fully until the vehicle has been
lowered. Failure to follow this warning may result in
personal injury.
FUEL REQUIREMENTS
3.6L Engine
Do not use E-85 flex fuel or ethanol blends greater than
15% in this engine.This engine is designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when
using high-quality unleaded “Regular”
gasoline having an octane rating of 87 as
specified by the (R+M)/2 method. The
use of higher octane “Premium” gaso-
line will not provide any benefit over “Regular” gasoline in
these engines.
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 gasoline 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 consider-
ing service for the vehicle.
5.7L Engine (With Automatic Transmission)
Do not use E-85 flex fuel or ethanol blends greater than
15% in this engine.
This engine is designed to meet all emis-
sions regulations and provide satisfac-
tory fuel economy and performance
when using high quality unleaded gaso-
line 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

Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon mon-
oxide 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
(Continued)
WARNING! (Continued)
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 main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.
