engine overheat JEEP COMPASS 2016 1.G Owners Manual

CAUTION!
Driving with a hot engine cooling system could
damage 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.
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
Vehicle”. Follow the warnings under the Cooling

Engine Temperature Warning Light
Red WarningLight 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.
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 tem-
perature reading does not return to normal, turn the engine off immediately and call for ser-
vice. Refer to “If Your Engine Overheats” in “What To Do In Emergencies” for further infor-
mation.

•Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
Mode by pushing the Recirculation button. However,
under certain conditions, while in Automatic Mode,
the system is blowing air out the defrost vents. When
these conditions are present, and the Recirculation
button is pushed, the indicator will flash and then turn
off. This tells you that you are unable to go into
Recirculation Mode at this time. If you would like the
system to go into Recirculation Mode, you must first
move the Mode knob to Panel, Bi-Level, Mix, or Floor
and then push the Recirculation button. This feature
reduces the possibility of window fogging.
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 must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
A solution of 50% OAT (Organic Additive Technology)
coolant that meets the requirements of FCA Material
Standard MS.90032 and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter 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 settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the AutoStick shift
control (refer to “AutoStick (Six-Speed Automatic Trans-
mission)” in this section for further information) to select
a lower gear. Under these conditions, using a lower gear
will improve performance and extend transmission life
by reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal operat-
ing limits, the transmission controller will modify the
transmission shift schedule and expand the range of
torque converter clutch engagement. This is done to
prevent transmission damage due to overheating. If the
transmission becomes extremely hot, the “Transmission
Temperature Warning Light” may illuminate and the
transmission may operate differently until the transmis-
sion cools down.During very cold temperatures (-4°F [-20°C] or below),
transmission operation may be modified depending on
engine and transmission temperature as well as vehicle
speed. Normal operation will resume once the transmis-
sion temperature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in fourth gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will continue
to operate. The Malfunction Indicator Light (MIL) may be
illuminated. Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service without dam-
aging the transmission.

further information) to select a lower gear ratio. Under
these conditions, using a lower gear ratio will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.During sustained high speed driving or trailer
towing up long grades on hot days, the auto-
matic transmission oil may become too hot. If
this happens, the transmission overheat indica-
tor light will come on, and the vehicle will slow slightly
until the transmission cools down enough to allow a
return to the requested speed. This is done to prevent
transmission damage due to overheating. If the high
speed is maintained, the overheating may reoccur, as
before, in a cyclic fashion. LOW (L) — If Equipped
Use this range for engine braking when descending very
steep grades. In this range, the transmission will down-
shift for maximum engine braking, and upshifts will
occur only to prevent engine overspeed.
AUTOSTICK
AutoStick (Six-Speed Automatic Transmission)
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system
can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.

•The system may revert to automatic shift mode if a
fault or overheat condition is detected.
To disengage AutoStick mode, hold the shift lever to the
right (+) until “D” is once again displayed in the instru-
ment cluster. You can shift in or out of the AutoStick
mode at any time without taking your foot off the
accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
AutoStick (CVT) — If Equipped
AutoStick is a driver-interactive transmission feature
providing six manually selectable gear ratios, giving you
more control of the vehicle. AutoStick allows you to maximize engine braking, eliminate undesirable upshifts
and downshifts, and improve overall vehicle perfor-
mance. This system can also provide you with more
control during passing, city driving, cold slippery condi-
tions, mountain driving, trailer towing, and many other
situations.
Operation
NOTE:
AutoStick is not available until the CVT warms
up in cold weather.
When the shift lever is in the DRIVE position, AutoStick
is activated by moving the shift lever side-to-side. Mov-
ing the shift lever to the right (+) will activate AutoStick
and shift up to the next higher manual ratio, unless you
are already operating in or near Overdrive, in which case
sixth gear ratio will be selected. In like manner, moving
the shift lever to the left (-) will activate AutoStick and
shift to the next lower manual ratio. The manually-
selected gear will be displayed in the instrument cluster.5
STARTING AND OPERATING 359

In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
unless an engine lugging or overspeed condition would
result. It will remain in the selected gear until another
upshift or downshift is chosen, except as described
below:
•The transmission will automatically upshift when nec-
essary to prevent engine over-speed.
• The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
• The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
• If a requested downshift would cause the engine to
overspeed, that shift will not occur. •
Transmission shifting will be more noticeable when
AutoStick is engaged.
• Heavy Anti-Lock Brake System (ABS) application will
disengage AutoStick mode.
• The system may revert to automatic shift mode if a
fault or overheat condition is detected.
To disengage AutoStick mode, hold the shift lever to the
right (+) until “D” is once again displayed in the instru-
ment cluster. You can shift in or out of the AutoStick
mode at any time without taking your foot off the
accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.

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 per-
formance and damage the emissions control sys-
tem.
• 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 ser-
vice. Contact your authorized dealer for service
assistance.
(Continued)
CAUTION! (Continued)
•The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentrations
of methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
instrument panel below the climate controls.Push the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional 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 flashers.
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 flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flashers
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.
• In city traffic — while stopped, place the transmission
in NEUTRAL, but do not increase engine idle speed.
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.
