GETTING TO KNOW YOUR VEHICLE 31

4. Fuel Gauge•The fuel gauge shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN mode.
•CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads

A single warning chime will sound with Low Fuel Warn-
ing.

WARNING!(Continued)
•If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, or brake fluid leaks are
suspected. The cause should be located and corrected
immediately.

SAFETY 251

WARNING!(Continued)
•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 improperly. Refer to “Jump
Starting Procedure” in “In Case Of Emergency” for
further information.
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 110-115 Volt AC electrical outlet with
a grounded, three-wire extension cord. For ambient temperatures below 0°F (-18°C), the engine
block heater is recommended. For ambient temperatures
below -20°F (-29°C), the engine block heater is required.
The engine block heater cord is routed under the hood,
behind to the driver ’s side headlamp. Follow the steps
below to properly use the engine block heater:
1. Locate the engine block heater cord (behind the driver ’s
side headlamp).
2. Undo the hook-and-loop strap that secures the heater cord in place.
3. Pull the cord to the front of the vehicle and plug it into a grounded, three-wire extension cord.
4. After the vehicle is running, reattach the cord to the hook-and-loop strap and properly stow away behind
the driver ’s side headlamp.
NOTE:
• The engine block heater cord is a factory installed
option. If your vehicle is not equipped, heater cords are
available from an authorized Mopar dealer.
• The engine block heater will require 110 Volts AC and 6.5
Amps to activate the heater element.

STARTING AND OPERATING 259

WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.
Refer to “Recreational Towing” in “Starting And Op-
erating” and “Towing A Disabled Vehicle” in “In Case
Of Emergency” for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick shift control
(refer to
AutoStick in this section for further information)
to select a lower gear. Under these conditions, using a
lower gear will improve performance and extend transmis-
sion life by reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the trans-
mission shift schedule, reduce engine torque, and/or ex-
pand the range of torque converter clutch engagement.
This is done to prevent transmission damage due to
overheating.
If the transmission becomes extremely hot, the “Transmis-
sion Temperature Warning Light” may illuminate and the
transmission may operate differently until the transmission
cools down.
During cold temperatures, transmission operation may be
modified depending on engine and transmission tempera-
ture as well as vehicle speed. This feature improves warm
up time of the engine and transmission to achieve maxi-
mum efficiency. Engagement of the torque converter
clutch, and shifts into 8th or 9th gear, are inhibited until the

provided to open the flapper door to allow emergency
refueling with a gas can.
1. Retrieve funnel from the rear cargo area.
2. Insert funnel into same filler pipe opening as the fuelnozzle.
3. Ensure funnel is inserted fully to hold flapper door open.
4. Pour fuel into funnel opening. 5. Remove funnel from filler pipe, clean off prior to putting
back in the spare tire storage area.
NOTE:
• When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.

366 STARTING AND OPERATING

•Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.

2. Connect the opposite end of the positive(+)jumper
cable to the positive (+)post of the booster battery.
3. Connect the negative (-)end of the jumper cable to the
negative (-)post of the booster battery.
4. Connect the opposite end of the negative (-)jumper
cable to a good engine ground (exposed metal part of
the discharged vehicle’s engine) away from the battery
and the fuel injection system.
