high gear. 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 ªTOW/HAULº button, when the transmis-
sion 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 tothe 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 Ð 5-Speed
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 Ð 5±Speed (NV3500)
1500 models are equipped with the NV3500 manual
transmission. Be sure the transmission is in 1st 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.
For most city driving you may find it
easier to use only 1st through 4th gear
ranges. For steady highway driving
with light accelerations, 5th gear is rec-
ommended. To shift into 5th gear, move
the shift lever to the right beyond the
spring pressure point and push it forward. When shifting
from 5th to 4th gear, pull the lever down toward you in
one motion. Do not pull the lever sharply left as you may
shift accidentally into 2nd gear and damage the trans-
mission.To shift into Reverse, come to a complete stop. Depress
the clutch and pause briefly to allow the gear train to
stop. Move the shift lever from the Neutral position
straight across and back into Reverse.
Never drive with your foot resting on the clutch pedal, or
attempt to hold the vehicle on a hill with the clutch pedal
partially engaged, as this will cause abnormal wear on
the clutch.
Recommended Vehicle Shift Speeds
To utilize your manual transmission efficiently for both
fuel economy and performance, it should be upshifted as
listed in the following chart. Shift at the vehicle speeds
listed for acceleration. Earlier upshifts during cruise
conditions (steady speeds) will result in increased fuel
economy, and may be used as indicated.

Downshifting
Moving from a high gear down to a lower gear is
recommended to preserve brakes when driving down
steep hills. In addition, downshifting at the right time
provides better acceleration when you desire to resume
speed. For acceleration at speeds less than 20 mph (30
km/h), 2nd gear is recommended.
FOUR-WHEEL- DRIVE OPERATION Ð IF

NOTE:Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options, or dealer-installed options,
must be considered as part of the total load on your
vehicle. Refer to the Certification label located at the
driver's door for the Gross Vehicle Weight Rating.
WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Perform the maintenance listed in the ªMaintenance
Schedulesº section of this manual (Section 8). When
towing a trailer, never exceed the Gross Axle Weight
Rating (GAWR), or Gross Combined Vehicle Weight
(GCVW).
CAUTION!
When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or damage
to brakes, axle, engine, transmission, steering, sus-
pension, body structure or tires.

Trailer Towing Recommendations
²
All trailer hitches should be professionally installed on
your vehicle.
²Safety chains must always be used between your
vehicle and trailer.
²Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury. An electrically±actuated electric trailer
brake controller is recommended.
²Trailer brakes are recommended for trailers over 1000
lbs (454 kg) and are required for trailers in excess of
2,000 lbs (907 kg)
²Use an approved wiring harness connector on the
trailer. Standard equipment on all RAM pickup mod-
els provides a 4-way trailer tow connector located
under the bumper. This connector contains the follow-
ing vehicle circuits: park/tail lamps, left stop/turn
lamp, right stop/turn lamp, and ground. With the
optional Trailer Tow Prep package a 7-way connector
is provided with the following additional circuits:
backup lamp, trailer battery and electric brake.
NOTE:Connect trailer lighting and brakes using factory
harnesses only. Do not cut or splice wiring to the brake
circuits.

during the 1 second time, then all of the mode position
indicator lights will flash continuously until all require-
ments are met or until the Neutral (N) button is released.
NOTE:The ignition key must be ON for a shift to take
place and for the position indicator lights to be operable.
If the key is not ON, the shift will not take place and no
position indicator lights will be on or flashing.
NOTE:Flashing neutral (N) position indicator light
indicates that shift requirements have not been met.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging the
parking brake. The transfer case Neutral (N) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
despite the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
290 STARTING AND OPERATING

If you experience unusual vibration after driving in mud,
slush or similar conditions, check the wheels for im-
pacted material. Impacted foreign material can cause a
wheel imbalance. Removing the foreign material from
the wheels will correct the situation.
TRACTION
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the car in front to avoid a collision in a sudden stop.
