WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing an accident
or personal injury.

NOTE: To select the proper gear position for maximum
deceleration (engine braking), simply press and hold the
ERS (-) switch down. The transmission will shift to the
range from which the vehicle can best be slowed down.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth and sixth gears). The trans-
mission will automatically shift into the Overdrive gear if
the following conditions are present:
•the shift lever is in the DRIVE position,
•the transmission fluid has reached an adequate tem-
perature,
•the engine coolant has reached an adequate tempera-
ture,
•vehicle speed is sufficiently high, and
•the TOW/HAUL switch has not been activated.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL switch to select TOW/
HAUL mode. This will improve performance and reduce
the potential for transmission overheating or failure due
to excessive shifting. When operating in TOW/HAUL
mode, transmission upshifts are delayed, and the trans-
mission will automatically downshift (for engine brak-
ing) during steady braking maneuvers.
62 STARTING AND OPERATING

NOTE:
•The torque converter clutch will not engage, and the
transmission will not shift to sixth gear, until the
transmission fluid and engine coolant are warm [usu-
ally after 1 to 3 miles (1.6 to 4.8 km) of driving].
Because sixth gear is disabled, and engine speed is
higher when the torque converter clutch is not en-
gaged, it may seem as if the transmission is not
shifting properly when cold. This is normal. Using the
Electronic Range Select (ERS) feature, when the trans-
mission is sufficiently warm, will demonstrate that the
transmission is able to shift into and out of Overdrive.
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission 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 after starting the engine.
Six-Speed Automatic Transmission – If Equipped
(Chassis Cab Only)
The shift lever position display (located in the instrument
panel cluster) indicates the transmission gear range. The
shift lever is mounted on the right side of the steering
column. You must press the brake pedal to move the shift
lever out of the PARK position (refer to “Brake/
Transmission Shift Interlock System” in this section). To
drive, move the shift lever from PARK or NEUTRAL to
the DRIVE position. Pull the shift lever toward you when
shifting into REVERSE or PARK, or when shifting out of
PARK.
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. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
64 STARTING AND OPERATING

WARNING!
Do not use the “TOW/HAUL” feature when driving
in icy or slippery conditions. The increased engine
braking can cause the rear wheels to slide, and the
vehicle to swing around with the possible loss of
vehicle control, which could cause an accident possi-
bly resulting in personal injury or death.
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
some accelerations, the clutch automatically disengages.NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant are warm [usu-
ally after 1 to 3 miles (1.6 to 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. Using the Electronic Range Select (ERS)
feature, when the transmission is sufficiently warm,
will demonstrate that the transmission is able to shift
into and out of Overdrive.
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission 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 con-
verter will refill within five seconds after starting the
engine.
74 STARTING AND OPERATING

JUMP STARTING
WARNING!
•To prevent personal injury or damage to clothing,
do not allow battery fluid to contact eyes, skin or
fabrics. Do not lean over a battery when connect-
ing jumper cables or allow cable clamps to touch
each other. Keep open flames or sparks away from
battery vent holes. Always wear eye protection
when working with batteries.
•Do not use a booster battery or any other booster
source that has a greater than 12 Volt system, i.e.,
do not use a 24 Volt power source.
NOTE: Replacement batteries should both be of equal
size to prevent damage to the vehicle’s charging system.
Your vehicle is equipped with two 12 Volt batteries. If it
becomes necessary to use a booster battery with jumper cables to start a vehicle’s engine because its batteries are
discharged, the following procedure should be used:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If the
indicator (if equipped) is light or yellow on either battery,
replace that battery.
CAUTION!
Use the jump start procedure only when the charge
indicator (if equipped) in both batteries is dark in the
center. Do not attempt jump starting when either
battery charge indicator (if equipped) is bright or
yellow. If the charge indicator (if equipped) has a
green dot in the center, failure to start is not due to a
discharged battery and cranking system should be
checked.

Fluid Level Check
This fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of the
filler plug hole with the vehicle in a level position.
Manual Transmission – If Equipped
Lubricant Selection
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Fluid Level Check
The fluid level can be checked by removing the filler
plug. If the level of the lubricant is more than 1/2 in
(12 mm) below the bottom of the filler hole while the
vehicle is on level ground, enough lubricant should be
added to bring the level to 1/4 in (6 mm) below the
bottom of the filler hole.
Automatic Transmission – If Equipped
Lubricant Selection
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Fluid Level Check – Ram Truck Only
The fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is at
normal operating temperature. At normal operating tem-
perature, the fluid cannot be held comfortably between
the fingertips. Operation of the transmission with an
improper fluid level will greatly reduce the life of the
transmission and of the fluid. Check the fluid level
whenever the vehicle is serviced.
To properly check the automatic transmission fluid level,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
124 MAINTAINING YOUR VEHICLE

7. Remove the dipstick again and note the fluid level on
both sides. The fluid level should be between the HOT
(upper) reference holes on the dipstick at normal operat-
ing temperature. Verify that a solid coating of oil is seen
on both sides of the dipstick. If the fluid is low, add
MOPARAS68RC Automatic Transmission Fluid or
equivalent as required into the dipstick tube. Do not
overfill. Never use any ATF other than MOPAR
AS68RC Automatic Transmission Fluid or equivalent.
After adding any quantity of oil through the dipstick
tube, wait a minimum of two minutes for the oil to fully
drain into the transmission before rechecking the fluid
level.
NOTE: If it is necessary to check the transmission below
the operating temperature, the fluid level should be
between the two COLD (lower) holes on the dipstick
with the fluid at approximately 70°F to 85°F (20°C to
30°C). If the fluid level is correctly established at room temperature, it should be between the HOT (upper)
reference holes when the transmission reaches 160°F to
175°F (70°C to 82°C).
CAUTION!
Be aware that if the fluid level is below 50°F (10°C),
it may not register on the dipstick. Do not add fluid
until the temperature is elevated enough to produce
a accurate reading.
8. Check for leaks. Release the parking brake.
NOTE: To prevent dirt and water from entering the
transmission after checking or adding fluid, make sure
that the dipstick cap is properly reseated. It is normal for
the dipstick cap to spring back slightly from its fully
seated position, as long as the seal remains engaged in
the dipstick tube.
