If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. 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 improp-
erly. Refer to “Jump Starting” in “What To Do In
Emergencies” for further information.

onds before trying again.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater cord is routed under the hood on
the driver side of the vehicle. It has a removable cap that
is located on the driver side of the Integrated Power
Module.
244 STARTING AND OPERATING

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 transmis-
sion is warm. This is a normal condition and is not an
indication of a problem with your clutch or
transmission.
1–4 Skip Shift
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 1/4 throttle or less.
The “1–4 Skip Shift Indicator Message” will be displayed
during these times.When the “1–4 Skip Shift Indicator Message” is dis-
played, the shift mechanism will only allow shifts from
first gear to fourth gear. 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, 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.
248 STARTING AND OPERATING

CAUTION!
•If you skip more than one gear while downshift-
ing or downshift at too high an engine speed, you
could damage the engine, transmission, 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.
AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the automatic transmission may occur if
the following precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
5
STARTING AND OPERATING 249

WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL if the engine speed is higher than idle
speed. If your foot is not firmly on 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 when your right foot is
firmly on the brake pedal.
General Information
The automatic transmission selects individual gears au-
tomatically, dependent upon:
•Altitude
•Vehicle loading
•Driving style
•Shift lever position
•Accelerator position
•Vehicle speed
The gear shifting process is continuously adapted, de-
pendent on the driving style, the driving situation, and
the road characteristics.
NOTE:
•After selecting any driving position, wait a moment to
allow the gear to engage fully before accelerating,
especially when the engine is cold.
•If there is a need to restart the engine, be sure to turn
the ignition switch to the LOCK position (OFF position
with Keyless Go™) before restarting. Transmission
engagement may be delayed up to 10 seconds after
restart if the ignition switch is not turned to the LOCK
position (OFF position with Keyless Go™) first.
250 STARTING AND OPERATING

•The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating. Therefore, the first few shifts on a new
vehicle may be somewhat abrupt or soft until after the
break-in period. This is a normal condition, and pre-
cision shifts will develop within a few shift cycles.
The shift lever is automatically locked while in the PARK
position. To move the shift lever out of the PARK
position, the brake pedal must be firmly pressed before
the shift lock will release.
Move the shift lever to the desired position only when the
engine is idling normally and the brake pedal is applied.
Do not release the brake pedal until ready to drive. The
vehicle may otherwise accelerate quickly when the shift
lever is in DRIVE or REVERSE position.WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should always
shift the transmission into PARK, remove the key fob
from the ignition, and apply the parking brake. Once
the key fob is removed from the ignition, the shift
lever is locked in the PARK position, securing the
vehicle against unwanted movement. Furthermore,
you should never leave unattended children inside a
vehicle.

STARTING AND OPERATING 251

Over-Temperature Mode
The transmission electronics constantly monitor the trans-
mission oil temperature. If the transmission exceeds nor-
mal operating temperature, the transmission will change
the way it shifts to help control the condition. This may
result in a slightly different feeling or response during
normal operation in DRIVE position. After the transmis-
sion cools down, it will return to normal operation.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
prior to rotating the key fob to the LOCK position. The
key fob can only be removed from the ignition when the
ignition is in the LOCK position and once removed the
shift lever is locked in PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock (BTSI) system that holds the shift lever in thePARK position when the ignition switch is in the LOCK
position (OFF position with Keyless Go™). To move the
shift lever out of the PARK position, the ignition switch
must be turned to any other ignition position (ACC,
ON/RUN or START) whether the engine is running or
not, and the brake pedal must be pressed.
Brake/Transmission Interlock Manual Override
There is an override for the BTSI that allows you to move
the shift lever out of the PARK position if an electrical
system malfunction occurs (i.e., dead battery). To access
the override (using a flat-bladed screwdriver), carefully
remove the override cover which is located on the right
of the shift lever.
1. Turn the ignition switch to the ACC or ON position
(RUN position with Keyless Go™) without starting the
engine.
2. Firmly set the parking brake.
252 STARTING AND OPERATING

3. Press and maintain firm pressure on the brake pedal.
4. Using the screwdriver, press and hold the override tab
through the access port on the center console.5. Move the shift lever into the NEUTRAL position.
6. The vehicle may then be started in NEUTRAL.
7. Reinstall the override cover.
With Keyless Go™
If the engine is running, press the START/STOP button to
turn it off. Release the brake pedal and press the START/
STOP button once or twice to go to the ACC or RUN
position. Do not start the engine. Then, follow the in-
structions shown above to activate the override.

STARTING AND OPERATING 253

Five-Speed Automatic Transmission
Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
pedal when moving the shift lever between these gears.
Gear Ranges
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Apply
the parking brake when leaving the vehicle in this range.
When parking on a flat surface, place the shift lever in the
PARK position first, and then apply the parking brake.
When parking on a hill, it is important to set the parking
brake before placing the shift lever in PARK, otherwise
the load on the transmission locking mechanism may
make it difficult to move the shift lever out of PARK. As
an added precaution, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
