engine coolant DODGE NITRO 2007 1.G Owners Manual

INSTRUMENT CLUSTER DESCRIPTION
1. Fuel Gauge
The fuel gauge shows level of fuel in tank when
ignition switch is in the ON position.
2. Fuel Cap Indicator
This symbol indicates the side of the vehicle
where the fuel cap is located.
3. Temperature Gauge
The temperature gauge indicates engine coolant
temperature. Any reading within the normal
range indicates that the cooling system is operat-
ing satisfactorily. The gauge needle will likely indicate a
high temperature when driving in hot weather, up moun-
tain grades, in heavy traffic, or when towing a trailer. If
the needle rises to the “H” mark, stop the vehicle, shiftinto N (Neutral) increase engine speed for 2-3 minutes. If
the temperature reading does not return to normal, seek
authorized service immediately.
CAUTION!
Do not leave your vehicle unattended with the
engine running as you would not be able to react to
the temperature indicator if the engine overheats.
The gauge pointer will remain near its last reading when
the engine is turned off. It will return to a true reading
when the engine is restarted.
4. Low Fuel Warning Light
This indicator lights when the fuel gauge reads 1/8
of a tank or less.

5. Seat Belt Reminder Light
This light comes on for several seconds after the
ignition is turned ON as a reminder to “buckle
up.” This light will remain on as long as the seat
belt remains unbuckled. If this light flashes, it indicates a
fault in the airbag system. Have the system checked by
an authorized dealer.
6. Coolant Temperature Warning Light
This light warns of an overheated engine condi-
tion. For a bulb check, this light will come on
momentarily when the ignition is turned On. If the
light turns on while driving, stop the vehicle, shift into N
(Neutral) and increase the engine speed for 2 to 3
minutes. If the temperature reading does not return to
normal, seek authorized service immediately.As temperatures rise and the gauge approachesH, this
indicator will illuminate and a single chime will sound
after reaching a set threshold. Further overheating will
cause the temperature gauge to passH, the indicator
will continuously flash, and a continuous chime will
occur until the engine is allowed to cool.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature light is on,
safely pull over and stop the vehicle. Idle the vehicle
in neutral with the air conditioner turned off until
the light turns off. If the if the light remains on, turn
the engine off immediately, and call for service.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7 of this manual. Follow
the warnings under the Cooling System Pressure
Cap paragraph.
7. Speedometer
Shows the vehicles speed.
8. High Beam Indicator Light
Indicates that headlights are on high beam.9. Security Alarm System Indicator Light — If
Equipped
This light will flash rapidly for approximately 15 seconds
when the vehicle theft alarm is arming. The light will
flash at a slower speed continuously after the alarm is set.
The security light will also come on for about three
seconds when the ignition is first turned on.
10. Electronic Stability Program (ESP) Warning
Light/Brake Assist System (BAS) Warning Light – If
Equipped
The malfunction lamp for the ESP is combined
with BAS. The yellow “ESP/BAS Warning
Lamp” and the yellow “ESP/TCS Indicator
Light” in the instrument cluster both come on
when the ignition switch is turned to the “ON” position.
They should go out with the engine running. If the
“ESP/BAS Warning Lamp” comes on continuously with
the engine running, a malfunction has been detected in
either the ESP or the BAS system. If this light remains on

To Manually Calibrate the Compass
Start the engine, and leave the transmission in the P
(Park) position. Press and hold (approximately 10 sec-
onds) the odometer/trip odometer reset button until the
current variance zone number is displayed. Release the
odometer/trip odometer reset button, then press and
hold again (approximately 10 seconds), until the direc-
tion is displayed with the “CAL” indicator on continu-
ously in the display. To complete the compass calibration,
drive the vehicle in one or more complete 360 degree
circles under 5 mph (8 km/h) in an area free from power
lines, large metallic objects, until the “CAL” indicator
turns off. The compass will now function normally.ELECTRONIC VEHICLE INFORMATION CENTER
(EVIC) — IF EQUIPPED
The Electronic Vehicle Information Center (EVIC) fea-
tures a driver-interactive display. It is located on the
instrument cluster in the lower half of the fuel/coolant

smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Fluids and
Genuine Parts in Section 7 for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift into
N (Neutral) and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.

ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant 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.
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.
MANUAL TRANSMISSION — IF EQUIPPED
6-Speed Manual Transmission
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the
vehicle, especially on an incline.

•the transmission selector is in D (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;
•transmission has reached normal operating tempera-
ture.
NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive
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 cooldown, the transmis-
sion 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

of the desired top gear. For example, if the driver shifts
the transmission into 3 (third gear), the transmission will
never shift above third gear, but can shift down to 2
(second) or 1 (first), when needed.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid.

NOTE:To select the proper gear position for maximum
deceleration (engine braking), move the shift lever to the
left “D(-)” and hold it there. The transmission will shift to
the range from which the vehicle can best be slowed
down.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled 5th speed (Overdrive). The trans-
mission will automatically shift from 4th gear to Over-
drive if the following conditions are present:
•the transmission selector is in D (Drive);
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 30 mph (48
km/h);
•transmission has reached normal operating tempera-
ture.
NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive
and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has

A clutch within the torque converter engages automati-
cally at a calibrated speed at light throttle. It engages at
higher speeds under heavier acceleration. This may re-
sult in a slightly different feeling or response during
normal operation in high gear. When the vehicle speed
drops below a calibrated speed, or during acceleration,
the clutch automatically and smoothly disengages. The
feature is operational in Overdrive and in Drive.
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.
Manually shifting between 3 (third gear) and 4 (fourth
gear) positions (using the ERS shift control) will demon-
strate 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.

Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, inspect the
exhaust system each time the vehicle is raised for lubri-
cation or oil change. Replace as required.
Cooling System
WARNING!
You or others can be badly burned by hot antifreeze/
coolant or steam from your radiator. If you see or
hear steam coming from under the hood, don’t open
the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
Engine Coolant Checks
Check antifreeze/coolant protection every 12 months
(before the onset of freezing weather, where applicable).
If antifreeze/coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
antifreeze/coolant. Check the front of the A/C condenser
(if equipped) or radiator for any accumulation of bugs,
leaves, etc. If dirty, clean by gently spraying water from a
