WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off the
jack and hurt someone near it. Raise the vehicle
only enough to remove the tire.

To avoid the risk of forcing the vehicle off the
jack, do not tighten the wheel nuts fully until the
vehicle has been lowered. Failure to follow this
warning may result in serious injury.

A loose tire or jack thrown forward in a collision
or hard stop, could endanger the occupants of
the vehicle. Always stow the jack parts and the
spare tire in the places provided.

whenever the hood is raised. It can start
anytime the ignition switch is ON. You can be
injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could make
an inadvertent electrical contact. You could be
seriously injured.
Batteries contain sulfuric acid that can burn
your skin or eyes and generate hydrogen gas
which is flammable and explosive. Keep open
flames or sparks away from the battery.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and
personal injury could result.
WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster
vehicle or the discharged vehicle.

Use only refrigerants and compressor lubri-
cants approved by the manufacturer for your
air conditioning system. Some unapproved
refrigerants are flammable and can explode,
injuring you. Other unapproved refrigerants or
lubricants can cause the system to fail,
requiring costly repairs. Refer to Warranty
Information Book, located in your owner’s
information kit, for further warranty informa -
tion.
WARNING!
WARNING!
Do not remove the cabin air filter while the
vehicle is running, or while the ignition is in the
ACC or ON/RUN mode. With the cabin air filter
removed and the blower operating, the blower
can contact hands and may propel dirt and
debris into your eyes, resulting in personal injury.

Use only the manufacturer recommended
brake fluid Úpage 456. 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 identified on the original factory installed
hydraulic master cylinder reservoir.
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.

WARNING!
When replacing a blown fuse, always use an
appropriate replacement fuse with the same
amp rating as the original fuse. Never replace
a fuse with another fuse of higher amp rating.
Never replace a blown fuse with metal wires or
any other material. Failure to use proper fuses
may result in serious personal injury, fire and/
or property damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
If the replaced fuse blows again, contact an
authorized dealer.
If a general protection fuse for safety systems
