2018 JEEP COMPASS engine overheat

CAUTION!
• Racing the engine or spinning the
wheels may lead to transmission over-
heating and failure. Allow the engine to
idle with the transmission in NEUTRAL
for at least one minute after every five
rocking-motion cycles. This will mini-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
CAUTION!
• When “rocking” a stuck vehicle by shift-
ing between DRIVE/ SECOND 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 dam-
age the tires. Do not spin the wheels
CAUTION!
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
TOWING A DISABLED
VEHICLE
This section describes procedures for towing
a disabled vehicle using a commercial towing
service.
Towing Condition Wheels OFF The
GroundFWD MODELS 4X4 MODELS
Flat Tow NONENOT ALLOWED NOT ALLOWED
Wheel Lift Or Dolly TowRearNOT ALLOWED NOT ALLOWED
Front OKNOT ALLOWED
FlatbedALL BEST METHOD ONLY METHOD
Proper towing or lifting equipment is required
to prevent damage to your vehicle. Use only
tow bars and other equipment designed for
this purpose, following equipment manufac-
turer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing
devices to main structural members of thevehicle, not to bumpers or associated brack-
ets. State and local laws regarding vehicles
under tow must be observed.
IN CASE OF EMERGENCY
216

Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage, and immediate service is required.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita-
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.

tions. If you experience these symptoms, try

Ethanol
The manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 10% ethanol. Purchasing your fuel from
a reputable supplier may reduce the risk of
exceeding this 10% limit and/or of receiving
fuel with abnormal properties.
CAUTION!
Use of fuel with Ethanol content higher
than 10% may result in engine malfunc-
tion, starting and operating difficulties,
and materials degradation. These adverse
effects could result in permanent damage
to your vehicle.
Materials Added To Fuel
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish re-
moval may contain active solvents or similar
ingredients. These can harm fuel system gas-
ket and diaphragm materials.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
• The use of leaded gasoline is prohibited
by law. Using leaded gasoline can impair
CAUTION!
engine performance 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 an autho-
rized 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 per-
formance 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.
