6. Press the red ENGINE START button located on the
instrument panel. Release the button when the engine
starts.If Engine Fails to Start
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
WARNING!
•Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to
start the vehicle. This could result in flash fire
causing serious personal injury.

136 STARTING AND OPERATING

WARNING! (Continued)
•Do not attempt to push or tow your vehicle to get
it started. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite
and damage the converter and vehicle. If the
vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly, so
follow this procedure carefully. See section 6 of
this manual for jump starting instructions.
If the engine is flooded, it may start to run, but not have
enough power to continue running when the ENGINE
START button is released. If this occurs, continue crank-
ing up to 15 seconds with the accelerator pedal pushed
all the way to the floor. Release the accelerator pedal and
the ENGINE START button once the engine is running
smoothly.If the engine shows no sign of starting after two 15 sec-
ond periods of cranking with the accelerator pedal held
to the floor, the NORMAL STARTING procedure should
be repeated.
After Starting
The idle speed will automatically decrease as the engine
warms up.
MANUAL TRANSMISSION
NOTE:The parking brake should be engaged and the
shift lever selector placed in REVERSE before leaving the
vehicle, especially when parked on an incline.
Your vehicle is equipped with a high torque capacity dual
disc clutch. The clutch pedal must be fully depressed to
the floor during each shift. As you release the clutch
pedal, lightly depress the accelerator pedal.

•Shifting gears during cold weather may require an
increased effort until the transmission lubricant is
warm. This is normal and not harmful to the transmis-
sion.
•Due to the high performance nature of your drivetrain,
a certain amount of noise from the transmission is
normal. This noise can be most noticeable when the
vehicle is idling in NEUTRAL with the clutch engaged
(clutch pedal released), but it may also be heard when
driving. The noise may also be more noticeable when
the transmission is warm. This noise is normal and is
not an indication of a problem with your clutch or
transmission.
Recommended Shift Speeds
To use your manual transmission for fuel economy it
should be upshifted as listed below. Shift at the vehicle
speeds listed for acceleration. Earlier upshifts duringcruise conditions (relatively steady speeds) will result in
increased fuel economy, and may be used as indicated.
MANUAL TRANSMISSION
RECOMMENDED SHIFT SPEEDS
1-2 2-3 3-4 4-5 5-6
mph 15 25 40 45 50
(km/h) (24) (40) (64) (72) (80)
Higher upshift speeds may be used to obtain a desired
acceleration rate.
Skip Shift Indicator Light
There are times when you must shift the transmis-
sion directly from FIRST gear to FOURTH gear
instead of from FIRST gear to SECOND gear. This is to
help you get the best possible fuel economy from your
vehicle. This occurs when engine coolant is higher than
106°F (41°C), and vehicle speed is greater than 12 mph
(19 km/h) but less than 20 mph (32 km/h), and engine
speed is less than 1,322 RPM, and the transmission is in
STARTING AND OPERATING 139

FIRST gear, and the accelerator is at 1/4 throttle or less.
The Skip Shift Indicator Light located in the tachometer
will turn Amber during these times.
When the indicator light turns amber, the shift mecha-
nism will only allow shifts from FIRST gear to FOURTH
gear. After you shift the transmission into FOURTH gear,
you can press the clutch in and shift to another forward
gear.
Downshifting - Proper downshifting will improve fuel
economy and prolong engine life.
To maintain a safe speed and prolong brake life, down-
shift to maintain a safe speed when descending a steep
grade.WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have an accident.
CAUTION!
If you skip more than one gear while downshifting
or downshift at too high an engine speed, you could
damage the engine, transmission, or clutch.
140 STARTING AND OPERATING

WARNING! (Continued)
•Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
•Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under-inflation also increases
tire rolling resistance and results in higher fuel
consumption.
Ride Comfort and Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side “B” Pillar.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than the
maximum loaded vehicle condition. These pressure con-
ditions will be found in the “Supplemental Tire Pressure
Information” section of this manual.
The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. DO NOT make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are under-inflated.

TPMS Malfunction Warning
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain
continuously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low
tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons,
including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue to function
properly.
FUEL REQUIREMENTS
8.4L Engine
The 8.4L engine is designed to meet all
emissions regulations and provide excel-
lent fuel economy and performance when
using high-quality premium unleaded
gasoline with an octane rating of 91 or
higher.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
170 STARTING AND OPERATING

Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of “premium” gasoline
before considering service for the vehicle.
Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) which
define fuel properties necessary to deliver enhanced
emissions, engine performance, and durability for your
vehicle. The manufacturer recommends the use of gaso-
lines that meet the WWFC specifications if they are
available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline.”
Reformulated gasolines contain oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol or E85
Ethanol. Use of these blends may result in starting
and driveability problems and may damage critical
fuel system components.
