engine overheat JEEP COMPASS 2017 2.G Owners Manual

The operator can override the AUTO mode setting to
change airflow distribution by rotating the Mode Control
knob (on the right).
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 “Dealer Service” in “Servicing And Maintenance” for
proper coolant selection.

2. Push and hold the desired HomeLink button until theindicator light begins to flash after 20 seconds. Do not
release the button.
3. Without releasing the button, proceed with “Program-
ming A Non-Rolling Code” step 2 and follow all remain-
ing steps.
Canadian/Gate Operator Programming
For programming transmitters in Canada/United States
that require the transmitter signals to “time-out” after
several seconds of transmission:
Canadian radio frequency laws require transmitter signals
to time-out (or quit) after several seconds of transmission,
which may not be long enough for HomeLink to pick up
the signal during programming. Similar to this Canadian
law, some U.S. gate operators are designed to time-out in
the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage door
or gate motor.
1. Cycle the ignition to the ON/RUN position. NOTE:
For vehicles equipped with Keyless Enter-N-Go,
place the ignition in the RUN position with the engine ON.
Make sure while programming HomeLink with the engine
ON that your vehicle is outside of your garage, or that the
garage door remains open at all times.
2. Place the hand-held transmitter 1 to 3 inches (3 to 8 cm) away from the HomeLink button you wish to program
while keeping the HomeLink indicator light in view.
3. Continue to push and hold the HomeLink button while you push and release (“cycle”) your hand-held trans-
mitter every two seconds until HomeLink has success-
fully accepted the frequency signal. The indicator light
will flash slowly and then rapidly when fully trained.
4. Watch for the HomeLink indicator to change flash rates. When it changes, it is programmed. It may take up to 30
seconds or longer in rare cases. The garage door may
open and close while you are programming.
5. Push and hold the programmed HomeLink button and observe the indicator light.

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.

DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through underdrive first, second, third, and fourth
gears, direct fifth gear and overdrive sixth gear. The DRIVE
position provides optimum driving characteristics under
all normal operating conditions.
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing heavy trailers), use the AutoStick shift control (refer
to “AutoStick (Six-Speed Automatic Transmission)” 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 operating
limits, the transmission controller will modify the trans-
mission shift schedule and expand the range of torque
converter clutch engagement. This is done to preventtransmission damage due to overheating. If the transmis-
sion becomes extremely hot, the “Transmission Tempera-
ture Warning Light” may illuminate and the transmission
may operate differently until the transmission 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 ab-
normal 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 damaging the trans-
mission.

STARTING AND OPERATING 209

AutoStick — If Equipped
When using the AutoStick shift control, select the highest
gear that allows for adequate performance and avoids
frequent downshifts. For example, choose4if the desired
speed can be maintained. Choose 3or2 if needed to
maintain the desired speed.
To prevent excess heat generation, avoid continuous driv-
ing at high RPM. Reduce vehicle speed as necessary to
avoid extended driving at high RPM. Return to a higher
gear or vehicle speed when grade and road conditions
allow.
Electronic Speed Control — If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission overheat-
ing, take the following actions:
City Driving
When stopped for short periods, shift the transmission into
NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

4. Connect the opposite end of the negative(-)jumper
cable to a good engine ground (exposed metal part of
the discharged vehicle’s engine) away from the battery
and the fuel injection system.
WARNING!
Do not connect the jumper cable to the negative (-) post
of the discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury. Only use the specific ground point, do
not use any other exposed metal parts.
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
6. Once the engine is started, remove the jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-)end of the jumper cable from
the engine ground of the vehicle with the discharged
battery.
2. Disconnect the opposite end of the negative (-)jumper
cable from the negative (-)post of the booster battery. 3. Disconnect the positive
(+)end of the jumper cable from
the positive (+)post of the booster battery.
4. Disconnect the opposite end of the positive (+)jumper
cable from the positive (+)post of the vehicle with the
discharged battery.
5. Reinstall the air intake duct.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when not
in use (i.e., cellular devices, etc.). Eventually, if plugged
in long enough without engine operation, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
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.
270 IN CASE OF EMERGENCY

•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.
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.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the pointer rises to the H (red) mark, the
instrument cluster will sound a chime. When safe, pull
over and stop the vehicle with the engine at idle. Turn
off the air conditioning and wait until the pointer
drops back into the normal range. If the pointer
remains on the H (red) mark for more than a minute,
turn the engine off immediately and call for service.
GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector cannot be
moved out of the PARK position, you can use the following
procedure to temporarily move the gear selector:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
3. Using a small screwdriver or similar tool, remove the
gear selector override access cover (located on the right
side of the gear selector housing).

IN CASE OF EMERGENCY 271

4. Turn the ignition switch to the ACC or ON/RUNposition, but do not start the engine.
5. Press and maintain firm pressure on the brake pedal.
6. Insert the screwdriver or similar tool into the access port, and push and hold the override release lever
forward.
7. Move the gear selector to the NEUTRAL position.
8. The vehicle may then be started in NEUTRAL.
9. Reinstall the gear selector override access cover.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Then shift back and forth between DRIVE and
REVERSE (with automatic transmission) or 2nd gear and
REVERSE (with manual transmission), while gently press-
ing the accelerator. Use the least amount of accelerator
pedal pressure that will maintain the rocking motion,
without spinning the wheels, or racing the engine.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce the
risk of clutch or transmission failure during prolonged
efforts to free a stuck vehicle.
Gear Selector Override Access Cover
272 IN CASE OF EMERGENCY

NOTE:Push the ESC Off switch, to place the Electronic
Stability Control (ESC) system in Partial Offmode, before
rocking the vehicle. Refer to “Electronic Brake Control” in
“Safety” for further information. Once the vehicle has been
freed, push the ESC Offswitch again to restore ESC On
mode.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s wheels
faster than 30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when you are
stuck and do not let anyone near a spinning wheel, no
matter what the speed.
CAUTION!
• When “rocking” a stuck vehicle by shifting between
DRIVE/2nd 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).
