engine overheat DODGE VIPER 2009 ZB II / 2.G Owners Manual

•If the light turns on steady while the engine is running,
safely bring the vehicle to a complete stop as soon as
possible, cycle the ignition key, and then restart the
engine. The light should turn off. However, if the light
remains on steady, see your authorized dealer for
service as soon as possible.
•If the light is flashing when the engine is running,
immediate service is required. If this occurs, you may
experience reduced vehicle performance, an elevated/
rough idle or engine stall, and your vehicle may
require towing.
Low Tire Pressure Telltale / TPMS Malfunction
Indicator
Each tire, including the spare (if provided),
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has tires ofa different size than the size indicated on the vehicle
placard or tire inflation pressure label, you should deter-
mine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.

6000 RPM. This serves as a visual aid to shift before
reaching the red line. This warning will turn off when the
tachometer pointer falls below 5900 RPM.
Coolant Temperature Gauge
This gauge shows the engine coolant tempera-
ture. The gauge pointer will likely show higher
temperatures when driving in hot weather, up
mountain grades, or in heavy stop and go
traffic. If the red Warning Light turns on while driving,
safely bring the vehicle to a stop, and turn off the engine.
DO NOT operate the vehicle until the cause is corrected.
Engine Temperature Warning Light
The red Engine Temperature Warning Light is
located in the Coolant Temperature Gauge. It will
turn on to warn of an overheated engine condi-
tion. If this light turns on while driving, safely bring the
vehicle to a stop and turn off the engine. DO NOT
operate the vehicle until the cause is corrected.
Oil Temperature Gauge
This gauge shows the oil temperature. The
gauge pointer will likely show higher tempera-
tures when driving in hot weather, up moun-
tain grades, or in heavy stop and go traffic. If
the red Warning Light remains on after the bulb check or
turns on while driving, safely bring the vehicle to a
complete stop and turn off the engine. DO NOT operate
the vehicle until the cause is corrected.
Oil Pressure Gauge
This gauge shows engine oil pressure when the
engine is running. The pressure will vary with
engine speed, oil viscosity, and engine tem-
perature. Oil pressures will be higher as the
engine is warming up. The normal operating pressure is
between 20 and 80 psi (pounds per square inch). If the
pointer remains in the red range, safely bring the vehicle
to a complete stop and turn off the engine. DO NOT
operate the vehicle until the cause is corrected.

Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to “Maintenance Procedures” in Section 7 of this manual
for proper coolant selection.
Winter Operation
•
Use the Defrost mode to direct cold air away from the
occupants during engine warm-up in cold weather.
•The blower air will heat faster in cold weather if you
use only the low blower speeds for the first ten
minutes of vehicle operation.
•Use of the air Recirculation mode during winter
months is not recommended because it may cause
window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will insure ad-
equate system lubrication to minimize the possibility of
compressor damage when the system is started again.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct any other occupant to buckle their seat
belt.
WARNING!
•Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
injured seriously or fatally. Don’t leave the keys in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
•Do not leave animals or children inside parked
vehicles in hot weather; interior heat build up may
cause serious injury or death.
(Continued)
WARNING! (Continued)
•Be sure to turn off the engine if you want to rest or
sleep in your car. Accidents can be caused by
inadvertently moving the gear selection lever or
by pressing the accelerator pedal. This may cause
excessive heat in the exhaust system, resulting in
overheating and vehicle fire, which may cause
serious or fatal injuries.
CAUTION!
Long periods of engine idling, especially at high
engine speeds, can cause excessive exhaust tempera-
tures, which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
134 STARTING AND OPERATING

content of gasoline may not be indicated on the pump,
you should ask your gasoline retailer if his/her gasoline
contains MMT.
It is even more important to look for gasolines without
MMT in Canada, because MMT can be used at levels
higher than allowed in the United States. MMT is pro-
hibited in Federal and California reformulated gasolines.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in additional cost. Therefore,
you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
or damage the emission control system.
•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out-of-tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.

HAZARD WARNING FLASHER
The Hazard Warning flasher switch is on the top of the
steering column, just behind the steering wheel.
Press the Hazard Warning flasher switch and all front
and rear directional signals will flash. Press the switch a
second time to turn the flashers off.Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.
If it is necessary to leave the vehicle to go for service, the
Hazard Warning flasher will continue to operate with the
ignition key removed.
NOTE:With extended use, the Hazard Warning flasher
may run down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways —Slow down and use the highest
gear possible.
•In city traffic —While stopped, put the transmission
in NEUTRAL, but do not increase engine idle speed.
Hazard Warning Switch
180 WHAT TO DO IN EMERGENCIES

•In city traffic —While moving, shift into the highest
gear possible to reduce engine RPM.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the cooling system and turning off the A/C removes this
heat. You can also turn the temperature control to maxi-
mum heat, the mode control to floor, and the fan control
to high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
cooling system.WARNING!
A hot cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant. If
your temperature gauge pointer is in the red area,
turn off the engine immediately. You may want to call
a service center for service. If you decide to look
under the hood yourself, see Section 7 of this manual.
Follow the warnings under the “Radiator Cap” para-
graph.
TIREFIT KIT
Small punctures in the tire tread can be sealed with
TIREFIT. Foreign objects (e.g., screws or nails) should not
be removed from the tire. TIREFIT can be used in outside
temperatures down to approximately -4°F (-20°C).

NOTE:The Vehicle Security Alarm System will prevent
the engine from starting.
12. Start the engine in the vehicle with the discharged
battery. If engine does not start in 15 seconds, stop
cranking engine and allow starter to cool down before
cranking again.
13. When removing the booster cables, reverse the above
sequence exactly. Be careful of the moving belts and fans.
WARNING!
Any procedure other than above could result in:
•Personal injury caused by electrolyte squirting out
the battery vent;
•Personal injury or property damage due to battery
explosion;
•Damage to charging system of booster vehicle or
of immobilized vehicle.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between RE-
VERSE and First gear. Usually the least accelerator pedal
pressure to maintain the rocking motion without spin-
ning the wheels is most effective.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transmission/axle overheating and fail-
ure. It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h).
