ECU JEEP PATRIOT 2010 1.G Service Manual

CAUTION!
•If the vehicle being towed requires steering, the
ignition switch must be in the ACC position, not
in the LOCK position.
•Do not attempt to use sling-type equipment when
towing. When securing the vehicle to a flatbed
truck, do not attach to front or rear suspension
components. Damage to your vehicle may result
from improper towing.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. A dolly should be
used under the front wheels if the rear wheels are raised.
Proper towing equipment is necessary to prevent dam-
age to the vehicle.Battery power is required to release the brake/
transmission interlock system (automatic transmission
only). There is a removable plug in the right side of the
shift lever housing that allows you to insert your finger to
override the system. The ignition key must be in the ON
position to use the override lever.
398 WHAT TO DO IN EMERGENCIES

WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also labeled on the origi-
nal factory installed hydraulic master cylinder
reservoir.(Continued)
WARNING! (Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep the
master cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly during hard
or prolonged braking, resulting in sudden brake
failure. This could result in a accident.
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.(Continued)
