Jacking Instructions
WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
•Always park on a firm, level surface as far from
the edge of the roadway as possible before raising
the vehicle.
•Block the wheel diagonally opposite the wheel to
be raised.
•Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
•Never start or run the engine with the vehicle on a
jack.(Continued)
WARNING! (Continued)
•Do not let anyone sit in the vehicle when it is on a
jack.
•Do not get under the vehicle when it is on a jack.
•Only use the jack in the positions indicated and
for lifting this vehicle during a tire change.
•If working on or near a roadway, be extremely
careful of motor traffic.
•To assure that spare tires, flat or inflated, are
securely stowed, spares must be stowed with the
valve stem facing the ground.
•Turn on the Hazard Warning flasher.
444 WHAT TO DO IN EMERGENCIES

WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
6. Remove the lug nuts and wheel.
7. Position the spare wheel/tire on the vehicle and install
the lug nuts with the cone-shaped end toward the wheel.
Lightly tighten the lug nuts clockwise. To avoid the risk
of forcing the vehicle off the jack, do not tighten the nuts
fully until the vehicle has been lowered.
8. Lower the vehicle by turning the jack screw to the left,
and remove the jack and wheel blocks.
9. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
nuts until each nut has been tightened twice. The correct wheel nut tightness is 95 ft lbs (130 N·m). If in doubt
about the correct tightness, have them checked with a
torque wrench by your authorized dealer or at a service
station.
10. Remove the jack assembly and wheel blocks.
11. Secure the tire, jack, and tools in their proper
locations.
WARNING!
A loose tire or jack, thrown forward in a collision or
hard stop, could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
JUMP-STARTING PROCEDURES
If your vehicle has a discharged battery it can be jump-
started using a set of jumper cables and a battery in
another vehicle or by using a portable battery booster
446 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)
