Dual Zone Temperature ControlUse this control to regulate the temperature of the air
inside the passenger compartment. This is accomplished
by having separate temperature control slides for both
the driver and front passenger. The blue area of the scale
indicates cooler temperatures while the red area indicates
warmer temperatures.
Electric Rear Window Defroster and Heated
Sideview Mirrors — If Equipped
The Electric Rear Window Defroster and Heated
side view mirrors are activated by pressing the
heated grid button, located on the Climate Control panel,
with the ignition On. Turning Off the ignition will
deactivate the Electric Rear Window Defroster and
Heated side view mirrors feature. These features also
turn off after activation, when 15 minutes have elapsed.
To reactivate, simply press the button again.

IGNITION/STARTER SWITCH LOCK
Locks the automatic transmission shift control into the
PARK position. It also engages the steering wheel lock (if
equipped) when the steering wheel is turned.
NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
depressed to shift out of Park (P).
OFF
Unlocks the steering wheel (if equipped with locking
wheel) and the automatic transmission shift control with
engine off.
ON
This is the normal running position.Ignition Switch Positions

START
Starts the engine. When the engine starts, release the key.
The ignition key will return to the ON position for
normal driving.
ACC
Allows the electrical accessories to be used when the
engine is not running.

To remove the key on vehicles equipped with manual
transmissions, turn the key to the Lock position and press
the button to remove the ignition key.

Key Reminder
An alarm will sound to remind you if the key is left in the
ignition and the driver’s door is opened.
STARTING PROCEDURES
The starter should not be operated for more than 15-
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
Manual Transmission
Apply the parking brake, place the gearshift control lever
in NEUTRAL and depress the clutch pedal to the floor
before starting the vehicle. This vehicle is equipped with
a clutch interlocking ignition system. It will not start
unless the clutch is fully depressed.
Automatic Transmission
Start the engine with the selector lever in NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Normal Starting of either a warm or cold engine is
obtained without pumping or depressing the accelerator
pedal. Turn the key to the START position and release
when the engine starts. If the engine fails to start within
10 seconds, turn the key to the OFF position, wait 5
seconds, then repeat the starting procedure.
NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
depressed to shift out of Park (P).

Torque Converter Clutch
A feature, designed to improve fuel economy, has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
acceleration when the transmission downshifts to second
gear, the clutch automatically disengages.
NOTE: The torque converter clutch will not engage
until the transmission fluid and engine coolant are warm
[usually after 1-3 miles (1.6 - 4.8 km) of driving]. Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmission
is not shifting into Overdrive when cold. This is normal.
Pressing the “TOW HAUL O/D OFF” button, when the
transmission is sufficiently warm, will demonstrate that
the transmission is able to shift into and out of overdrive. NOTE:
If the vehicle has not been driven in several
days, the first few seconds of operation after shifting the
transmission into gear may seem sluggish. This is due to
the fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds of shifting from Park into
any other gear position.
Manual Transmission
NOTE: The parking brake should be engaged before
leaving the vehicle, especially on an incline.
Truck models with manual transmission are equipped
with a clutch interlocking ignition system. The clutch
pedal must be fully depressed to start the vehicle.
Fully depress the clutch pedal before shifting gears. As
you release the clutch pedal, lightly depress the accelera-
tor pedal.

Manual Transmission — 6-Speed (G238)
NOTE: The parking brake should be engaged before
leaving the vehicle, especially on an incline.
1500 models are equipped with a G238 manual transmis-
sion. This transmission has a clutch interlocking ignition
system. The clutch pedal must be fully depressed to start
the vehicle. Fully depress the clutch pedal before shifting gears. As
you release the clutch pedal, lightly depress the accelera-
tor pedal. When launching a stationary vehicle, keep the
engine speed low until the clutch is fully engaged.
For improved clutch life, all six forward gears should be
used. For steady highway driving with light acceleration,
6th gear is recommended. When shifting from 5th to 6th
gear, do not apply excessive knob load toward the
Reverse gear gate, as you may overpower the Reverse
“crash-through” load and unintentionally clash into Re-
verse gear. Also, when shifting from 6th to 5th gear,
excessive knob load toward the Reverse gear gate will
result in blocking of the shift.
You should use first gear when starting from a standing
position. Damage to the clutch can result from starting in
2nd or 3rd gear. Use each gear in numerical order – do
not skip a gear.

stopped, the ignition key must be in the ON position with
the engine either RUNNING or OFF. This shift cannot be
completed if the key is in the accessory position.
2WD or 4 AUTO or 4 HI ⇔4LO
NOTE: When shifting into or out of 4WD LO some gear
noise may be heard. This noise is normal and is not
detrimental to the vehicle or occupants.
Shifting can be performed with the vehicle rolling 2 to 3
mph (3 to 5 km/h) or completely stopped. USE EITHER
OF THE FOLLOWING PROCEDURES:
Preferred Procedure
1. With engine RUNNING, slow vehicle to 2 to 3 mph (3
to 5 km/h).
2. Shift the transmission into NEUTRAL (depress clutch
on manual transmissions). 3. While still rolling, rotate the transfer case control
switch to the desired position.
4. After the desired position indicator light is ON (not
flashing), shift transmission back into gear (release clutch
on manual transmissions).
Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the key ON and the engine either OFF or
RUNNING, shift the transmission into NEUTRAL (de-
press clutch on manual transmissions).
3. Rotate the transfer case control switch to the desired
position.
4. After the desired position indicator light is ON (not
flashing), shift transmission back into gear (release clutch
on manual transmissions).
