about the correct tightness, have them checked with a
torque wrench by your authorized dealer or at a service
station.

CAUTION!
•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.
•If the vehicle being towed requires steering. the
ignition switch must be in the ON/RUN or ACC
position, not the LOCK/OFF position.
Towing Without The Ignition Key Fob
Special care must be taken when the vehicle is towed
with the ignition in the LOCK/OFF position. The only
approved method of towing without the ignition key is
with a flatbed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.
Four–Wheel Drive Models
The manufacturer recommends towing with all wheels
OFFthe ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of the vehicle raised
and the opposite end on a towing dolly.
500 WHAT TO DO IN EMERGENCIES

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 collision.
•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)
WARNING! (Continued)
•Do not allow petroleum based fluid to contami-
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in a collision.
Automatic Transmission – If Equipped
Selection Of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturer’s recommended transmis-
sion fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion. It is important that the transmission fluid be main-
tained at the prescribed level using the recommended
fluid.
