Rear Rotary Blower Control
The second row seat occupants have control of the rear
blower speed only when the front control unit is in the
ªREAR CONTROLº position or ªCONTROL IN REAR
for ATC.9
The rear blower switch has an OFF position and a range
of blower speeds. Rotating the rear blower control clock-
wise will increase the blower speed.
Rear Rotary Temperature Control
The second row seat occupants have control of the rear
temperature only when the front control unit is in the
9REAR CONTROL9position.
To change the temperature in the rear of the vehicle,
rotate the temperature control knob to the right or left.
The blue area indicates cooler temperatures while the red
area indicates warmer temperatures.NOTE:For best operation, make sure that ventilation
grilles located in the rear storage area are not obstructed
by stowed articles.

Tip Start Feature
Do notpress the accelerator. 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.
Extremely Cold Weather (below220ÉF or229ÉC)
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!
²Never 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.

276 STARTING AND OPERATING
Page 279 of 481

WARNING! (Continued)
²Do 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 Section 6 of
this manual for proper jump starting procedures
and follow them carefully.
If the engine fails to start after you have followed the
ªNormal Startingº or ªExtreme Cold Weatherº 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 andrelease 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
seconds before trying again.
After Starting
The idle speed is automatically controlled on fuel injected
engines and will decrease as the engine warms up.

ENGINE BLOCK HEATER ± IF EQUIPPED
The engine block heater warms the engine coolant 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.
Use the heater when temperatures below 0ÉF (-18ÉC) are
expected to last for several days.
The block heater must be plugged in at least one hour to
have an adequate warming effect on the coolant.
The engine block heater cord is located:
²4.7L Engine Ð at the front of the engine compartment
near the radiator cap.
²5.7L Engine Ð on the left side of the engine compart-
ment and rearward of the power distribution center.
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:
²Shift into PARK only after the vehicle has come to
a complete stop.
²Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
(Continued)
278 STARTING AND OPERATING
Page 281 of 481

CAUTION! (Continued)
²Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
²Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
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 foot is
firmly on the brake pedal.
Brake/Transmission Interlock System
This system prevents you from moving the shift lever out
of PARK and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position. Always depress thebrake
pedal first,before moving the gear selector out of PARK.
Gear Ranges
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold. If
there is a need to restart the engine, be sure to cycle the
key to the LOCK position before restarting. Transmission
gear engagement may be delayed after restarting the
engine if the key is not cycled to the LOCK position first.

PARK
This gear 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.
Always apply the parking brake first, then place the shift
lever into the PARK position.
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.
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.
REVERSE
Use this range only after the vehicle has come to a
complete stop.
NEUTRAL
Shift to NEUTRAL when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
