transmission DODGE NITRO 2009 1.G Owner's Manual

After Starting
The idle speed will automatically decrease as the engine
warms up.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup may
cause serious injury or death.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, 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.
•The engine block heater cord is found under the hood
clipped to the heater line on the left side of the engine.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 Volt AC electrical cord could
cause electrocution.
Use the heater when temperatures below 0 °F (-18 °C) are
expected to last for several days.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
(Continued)
262 STARTING AND OPERATING

CAUTION! (Continued)
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before 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. Always depress thebrake pedal first,before
moving the shift lever out of PARK.

Brake/Transmission Interlock Manual Override
Your vehicle may be equipped with a shift lock manual
override. The manual override may be used in the event
that the shift lever should fail to move from PARK with
the key in the ON position and the brake pedal de-
pressed. To operate the shift lock manual override, per-
form the following steps:
1. Turn the key to the ON position but do not start the
engine.
2. Firmly set the parking brake.
3. Using a flat blade screwdriver, carefully remove the
shift lock manual override cover which is located on the
PRNDL bezel.
4. Depress and maintain firm pressure on the brake
pedal.
5. Using the screwdriver, reach into the manual override
opening. Press and hold the shift lock lever down.6. Move the shift lever into the NEUTRAL position.
7. The vehicle may then be started in NEUTRAL.
Have your vehicle inspected by your local authorized
dealer if the shift lock manual override has been used.

264 STARTING AND OPERATING

4–Speed Automatic Transmission (3.7L Engine)
NOTE:Under extreme cold temperatures (-6°F (-21°C)
and when in DRIVE, transmission operation may be
briefly limited to only 2nd gear operation. Normal op-
eration will resume once the transmission temperature
has risen to a suitable level.
Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
when moving the shift lever between these gears.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL position into another gear range.

PARK
This gear position 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 in 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! (Continued)
•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.
266 STARTING AND OPERATING

NEUTRAL
Move the shift lever into this gear only after the vehicle
has come to a complete stop. Always depress and main-
tain firm pressure on the brake pedal while in this range.
Apply the parking brake when leaving the vehicle in this
range for extended periods of time. The engine may be
started in this range.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with shift lever in NEUTRAL can result in
severe transmission damage. Refer to “Recreational Tow-
ing” in Section 5 and “Towing a Disabled Vehicle” in
Section 6 of this manual.
DRIVE
For most city and highway driving.
2 (Second)
For moderate grades and to assist braking on dry pavement
or in mud and snow. Begins at a stop in low gear with
automatic upshift to 2nd gear. Will not shift to 3rd gear.
1 (First)
For hard pulling at low speeds in mud, sand, snow, or on
steep grades. Begins and stays in low gear with no upshift.
Provides engine compression braking at low speeds.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled 4th speed (OVERDRIVE). The trans-
mission will automatically shift from 3rd gear to OVER-
DRIVE if the following conditions are present:
•the shift lever is in DRIVE
•the engine coolant has reached normal operating tem-
perature
•vehicle speed is above approximately 30 mph
(48 km/h)
•the TOW/HAUL button has not been activated
•the transmission has reached normal operating
temperature
STARTING AND OPERATING 267

NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into OVER-
DRIVE and will automatically select the most desirable
gear for operation at this temperature. Normal operation
will resume when the transmission fluid temperature has
risen to a suitable level. Refer also to the note under
torque converter clutch, later in this section.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough, the “Transmission
Temperature Warning Light” may illuminate and the
transmission may downshift out of OVERDRIVE until
the transmission cools down. After the transmission cools
down, the transmission will resume normal operation.The transmission will downshift from OVERDRIVE to
DRIVE if the accelerator pedal is fully depressed at
vehicle speeds above approximately 35 mph (56 km/h).
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 button. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in TOW/HAUL mode, the transmission will
shift to 3rd gear.
268 STARTING AND OPERATING

NOTE:TOW/HAUL mode locks out Overdrive.
The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the TOW/HAUL mode is desired, the
switch must be pressed each time the engine is started.
Transmission Limp Home Mode
Transmission function is monitored for abnormal condi-
tions. If a condition is detected that could result in
transmission damage, the Transmission Limp Home
Mode will be engaged. In this mode, the transmission
will remain in 2nd gear in any forward driving range.
To reset the transmission, use the following procedure:
1. Stop the vehicle.
2. Move the shift lever to the PARK position.
3. Turn OFF the engine and be sure to turn the key to the
LOCK position.
4. Wait approximately 10 seconds, then restart the en-
gine.
5. Move the shift lever to the desired gear range.

If the problem is no longer detected, the transmission will
return to normal operation. If the problem persists,
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. Only 2nd gear range will operate in the DRIVE
position. Have the transmission checked at your autho-
rized dealer as soon as possible.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.
5–Speed Automatic Transmission (4.0L Engine)
The electronically controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a newvehicle may be somewhat abrupt. This is a normal
condition and precision shifts will develop within a few
hundred miles/kilometers.

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 position 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 in 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.
•It is dangerous to shift the selector 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.
