conditioning. An indicator in the button illuminates
when manual compressor operation is selected.
NOTE:To control the air conditioning manually, the
mode selector must be moved out of the AUTO position.
•Recirculation Control This button can be used to block out smoke,
odors, dust, high humidity, or if rapid cooling
is desired. The Recirculation mode should only
be used temporarily. An indicator in the button
illuminates when the Recirculation mode is active. You
may use this feature separately.
NOTE: Extended use of recirculation may cause the
windows to fog. If the interior of the windows begins to
fog, press the recirculation button to return to outside air.
Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper visibil-
ity. For this reason, the system will not allow recirculation
to be selected while in Defrost or Defrost/Floor mode. Attempting to use the recirculation while in these modes
will cause the indicator in the control button to blink and
then turn off.
Operating Tips
NOTE:
Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.

Normal Starting (Tip Start)
NOTE:Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.
Do not press the accelerator. Use the Fob with Integrated
Key to briefly turn the ignition switch to the START
position and release it as soon as the starter engages. The
starter motor will continue to run, and it will disengage
automatically when the engine is running. If the engine
fails to start, the starter will disengage automatically in
10 seconds. If this occurs, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
Extreme Cold Weather (Below 20°F or29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
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.
(Continued)
264 STARTING AND OPERATING
Page 266 of 484

WARNING! (Continued)
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission 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 dis-
charged 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 dan-
gerous if done improperly. Refer to “Jump Start-
ing” in “What To Do In Emergencies” for further
information.
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” proce-
dures, it may be flooded. To clear any excess fuel, push
the accelerator pedal all the way to the floor and hold it.
Then, turn the ignition switch to the START position and release it as soon as the starter engages. The starter motor
will disengage automatically in 10 seconds. Once this
occurs, release the accelerator pedal, turn the ignition
switch to the LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to 15 sec-
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.

STARTING AND OPERATING 265
Page 267 of 484
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.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 Volt electrical cord could cause
electrocution.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing 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.
266 STARTING AND OPERATING
Page 268 of 484

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 before re-
starting. Transmission engagement may be delayed up
to 10 seconds after restart if the ignition switch is not
turned to the LOCK position first.

STARTING AND OPERATING 267

•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 the 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 switch, and apply the parking
brake. Once the key fob is removed from the ignition
switch, 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.
Over-Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission exceeds
normal operating temperature, the transmission will
change the way it shifts to help control the condition.
