82STARTING AND OPERATING
ENGINE BREAK-IN RECOMMENDATIONS —
3.6L & 5.7L
A long break-in period is not required for the
drivetrain (engine, transmission, clutch, and rear
axle) in your new 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. However, wide-open throttle acceleration
in low gear can be detrimental and should be
avoided.
The engine oil, transmission fluid, and axle
lubricant installed at the factory are high-quality
and energy-conserving. Oil, fluid, and lubricant
changes should be consistent with anticipated
climate and conditions under which vehicle
operations will occur. For the recommended
viscosity and quality grades Ú page 306.
NOTE: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 interpreted as an indication of difficulty.
Please check your oil level with the engine oil indi -
cator often during the break in period. Add oil as
required.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied and place the gear
selector in the PARK or REVERSE (manual
transmission only) position.
When the parking brake is applied and the ignition
switch is in the ON/RUN position, the Brake
Warning Light in the instrument cluster will
illuminate.
NOTE:
When the parking brake is applied and the
transmission is placed in gear, the Brake
Warning Light will flash. If vehicle speed is
detected, a chime will sound to alert the driver.
Fully release the parking brake before
attempting to move the vehicle.
This light only shows that the parking brake is
applied. It does not show the degree of brake
application. When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade. For
vehicles equipped with an automatic transmission,
apply the parking brake before placing the gear
selector in PARK, otherwise the load on the
transmission locking mechanism may make it
difficult to move the gear selector out of PARK. The
parking brake should always be applied whenever
the driver is not in the vehicle.
Manual Transmission — If Equipped
The foot operated parking brake is positioned
below the lower left corner of the instrument panel.
To release the parking brake, pull the parking
brake release handle.

Parking Brake Release

CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.

MANUAL TRANSMISSION — IF EQUIPPED
SIX-SPEED MANUAL TRANSMISSION
WARNING!

Never use the PARK position as a substitute for
the parking brake. Always apply the parking
brake fully when parked to guard against vehicle
movement and possible injury or damage.

When exiting the vehicle, always remove the
key fob from the ignition and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil -
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the gear
selector.
When exiting the vehicle, always make sure
the keyless ignition node is in the OFF mode,
remove the key fob from the vehicle and lock
the vehicle.
Do not leave the key fob in or near the vehicle
or in a location accessible to children, and do
not leave the ignition of a vehicle equipped
with Keyless Enter ‘n Go™ in the ACC or ON/
RUN mode. A child could operate power
windows, other controls, or move the vehicle.
Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to
brake failure and a collision.
Always fully apply the parking brake when
leaving your vehicle, or it may roll and cause
damage or injury. Also be certain to leave the
transmission in PARK. Failure to do so may
allow the vehicle to roll and cause damage or
injury.
WARNING!CAUTION!
If the Brake Warning Light remains on with the
parking brake released, a brake system
malfunction is indicated. Have the brake system
serviced by an authorized dealer immediately.
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should
always be applied when the driver is not in the
vehicle, especially on an incline.
CAUTION!
Never drive with your foot resting on the clutch
pedal, or try to hold the vehicle on a hill with
the clutch pedal partially engaged, as this will
cause abnormal wear on the clutch
Ú page 182.

84STARTING AND OPERATING
NOTE:During cold weather, you may experience
increased effort in shifting until the transmission
fluid warms up. This is normal.

Manual Gear Selector

SHIFTING
Fully press the clutch pedal and lift your foot off the
accelerator pedal before shifting gears. As you
release the clutch pedal, lightly press the
accelerator pedal. Damage to the transmission or
clutch may occur if you do not fully press the clutch
pedal and lift off of the accelerator pedal when
shifting.
Shift Pattern
The six-speed manual transmission has a spring
that centers the gear selector near THIRD and
FOUTH gear. This spring helps you know which gear
you are in when you are shifting. Be careful when
shifting from FIRST to SECOND or downshifting
from SIXTH to FIFTH.
The spring will try to pull the gear selector toward
THIRD and FOURTH gear. Make sure you move the
gear selector into SECOND or FIFTH gear. If you let
the gear selector move in the direction of the
pulling, you may end shifting from FIRST to
FOURTH or from SIXTH to THIRD gear.
You must always use FIRST gear (or REVERSE)
when starting from a standing position.Failure to press the clutch pedal fully to the
floor may cause increased shift efforts, and
may result in damage to the clutch and trans
-
mission.
Do not rest your hand on the gear selector
while driving, as this may result in transmis -
sion synchronizer damage.
Do not attempt to shift the transmission if the
rear wheels are spinning due to loss of trac -
tion. Damage to the transmission may occur.
CAUTION!
CAUTION!
Always make sure the vehicle comes to a
complete stop before shifting into REVERSE.
Failure to do so may result in transmission
damage.

21_LA_OM_EN_USC_t.book Page 84

STARTING AND OPERATING85
RECOMMENDED SHIFT SPEEDS
To utilize your manual transmission efficiently for fuel economy, it should be upshifted as listed in recommended shift speed chart.
Earlier upshifts during cruise conditions (relatively steady speeds) may result in increased fuel economy.
Higher upshift speeds may be used to obtain a desired acceleration rate.
NOTE:
Your vehicle is equipped with a transmission reverse inhibitor system. Always depress the clutch pedal fully to the floor before shifting into REVERSE. When
vehicle speed is greater than 3 mph (5 km/h), the reverse inhibitor activates to help prevent shifts into REVERSE. When at a complete stop, you may notice
lighter shift efforts into REVERSE with the ignition switch in the ON position (RUN position for Keyless Enter ‘n Go™), as compared to the ignition LOCK position
(OFF position for Keyless Enter ‘n Go™). This is normal operation of the transmission reverse inhibitor system.
Due to the high performance nature of your drivetrain, you may hear your transmission. This 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 at low engine RPM. Also, this may be more noticeable when the trans -
mission is warm. This is a normal condition and is not an indication of a problem with your clutch or transmission.

86STARTING AND OPERATING
(Continued)
(Continued)
1–4 SKIP SHIFT
In Auto Drive Mode, Default, or Street Drive Modes,
there are times when you must shift the
transmission 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 the
engine coolant (antifreeze) is higher than 106°F
(41°C), vehicle speed is greater than 19 mph
(30 km/h) but less than 21 mph (34 km/h), and
the transmission is in FIRST gear, and the
accelerator is at ¼ throttle or less.
After you shift the transmission to FOURTH gear,
you can press the clutch in and shift to another
forward gear.
DOWNSHIFTING
To maintain a safe speed and prolong brake life,
downshift to maintain a safe speed when
descending a steep grade.
AUTOMATIC TRANSMISSION —
IF EQUIPPED
You must press and hold the brake pedal while
shifting out of PARK.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle.
You could have a collision.
CAUTION!
If you skip more than one gear while down -
shifting or downshift at too high an engine
speed, you could damage the engine, trans -
mission, or clutch.

Do not downshift into FIRST gear when the
vehicle is moving faster than 15 mph
(24 km/h), as you could damage the engine
and/or clutch.

WARNING!
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when exiting the vehicle to
guard against vehicle movement and possible
injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting the vehicle.
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi -
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.
WARNING!
