2017 DODGE VIPER engine overheat

Instrument Cluster Descriptions
1. Speedometer•Indicates vehicle speed.
2. Tachometer •Indicates the engine speed in revolutions per minute
(RPM x 1000).
3. Temperature Gauge •The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather or up mountain
grades. It should not be allowed to exceed the upper
limits of the normal operating range.
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 an authorized dealer for
service if your vehicle overheats. If you decide to look

under the hood yourself, see “Maintaining Your Ve-
hicle”. Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H”, turn the engine off immediately and call an
authorized dealer for service.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.

Vehicle Security Warning Light — If Equipped
Red TelltaleLight What It Means
Vehicle Security Warning Light — If Equipped
This light will flash at a fast rate for approximately 15 seconds when the vehicle security alarm is
arming, and then will flash slowly until the vehicle is disarmed.
Engine Temperature Warning Light
Red Warning
Light What It Means
Engine Temperature Warning Light
This light warns of an overheated engine condition. As engine coolant temperatures rise and the
gauge approaches
H, this indicator will illuminate and a single chime will sound after reaching a
set threshold. Further overheating will cause a continuous chime sound for 4 minutes, or until
the engine is allowed to cool, whichever comes first.
If the light turns on while driving, safely pull over and stop the vehicle. If the A/C system is on,
turn it off. Also, shift the transmission into NEUTRAL and idle the vehicle. If the temperature
reading does not return to normal, turn the engine off immediately and call for service. Refer to
“If Your Engine Overheats” in “What To Do In Emergencies” for further information.

3. When the system is set up for your comfort level, it isnot necessary to change the settings. You will experience
the greatest efficiency by simply allowing the system to
function automatically.
NOTE:
• It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode, and blower speed to provide
comfort as quickly as possible.
• The temperature can be displayed in U.S. or Metric units
by selecting the US/Metric customer-programmable fea-
ture. Refer to “Uconnect Settings” in this section of the
manual.
To provide you with maximum comfort in the Automatic
mode during cold start-ups, the blower fan will remain on
low until the engine warms up. The blower will increase in
speed and transition into Auto mode.
Manual Operation Override
This system offers a full complement of manual override
features. The AUTO symbol in the front ATC display will
be turned off when the system is being used in the manual
mode. NOTE:
The system will not automatically sense the pres-
ence of fog, mist or ice on the windshield. DEFROST mode
must be manually selected to clear the windshield and side
glass.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended. Refer
to “Maintenance Procedures” in “Maintaining Your Ve-
hicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for proper coolant selection.
Use of the air Recirculation mode during Winter months is
not recommended because it may cause window fogging.

In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the brakes
will still function. However, the effort required to brake the
vehicle will be much greater than that required with the
power system operating.
Brake Pad Break-In
NOTE:Your vehicle is equipped with a high performance
braking system. The brake pads are a semi-metallic com-
pound, which offer superior fade resistance for consistent
operation. A compromise to using this type of brake pad is
that the brakes may squeal slightly under certain weather
and operating conditions (.i.e., during light brake applica-
tions).
The brakes on your new vehicle do not require a long
break-in period. However, you should avoid repeated hard
brake applications from high speeds during initial break-
in. In addition, you should avoid severe brake loading,
such as may be encountered when descending long moun-
tain grades.
For ACR models, please review the supplemental manual
for CCM brake pad and rotor burnishing.
Safe Operating Tips
WARNING!
To use your brakes and accelerator more safely, follow
these tips:
• Do not “ride” the brakes by resting your foot on the
pedal. This could overheat the brakes and result in
unpredictable braking action, longer stopping dis-
tances, or brake damage.
• When descending mountains or hills, repeated brak-
ing can cause brake fade with loss of braking control.
Avoid repeated heavy braking by downshifting the
transmission whenever possible.
• Do not drive too fast for road conditions, especially
when roads are wet or slushy. A wedge of water can
build up between the tire tread and the road. This
hydroplaning action can cause loss of traction, brak-
ing ability, and control.
• After going through deep water or a car wash, brakes
may become wet, resulting in decreased performance
and unpredictable braking action. Dry the brakes by
gentle, intermittent pedal action while driving at
very slow speeds.
204 STARTING AND OPERATING

Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion, and
stability additives are recommended. Using gasolines that
have these additives will help improve fuel economy,
reduce emissions, and maintain vehicle performance.Designated TOP TIER Detergent Gaso-
line contains a higher level of detergents
to further aide in minimizing engine
and fuel system deposits. When avail-
able, the usage of Top Tier Detergent
gasoline is recommended. Visit
www.toptiergas.com for a list of TOP
TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents should be
avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and dia-
phragm materials.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
• The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor-
mance and damage the emissions 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.
• The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most of
these products contain high concentrations of metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty.

HAZARD WARNING FLASHER
The Hazard Warning flasher switch is located in the center
of the instrument panel above the climate controls.Push the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming traffic
of an emergency. Push the switch a second time to turn off
the Hazard Warning flasher.
This is an emergency warning system and it should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flasher will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flasher
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
• 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.
• 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 (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
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.
246 WHAT TO DO IN EMERGENCIES

CAUTION!
•When “rocking” a stuck vehicle by shifting between
1st gear and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis-
sion shifting occurring).
TOWING A DISABLED VEHICLE
Do not tow with sling-type equipment. Only use flatbed
equipment. Always comply with applicable state or local
towing ordinances.
CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe transmission damage. Damage
from improper towing is not covered under the New
Vehicle Limited Warranty.
