Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the BRAKE warning light shows system failure
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
fluid reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. Brake fluid level

Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder, which will
scratch metal and painted surfaces.
Appearance Care For Fabric Top Models
CAUTION!
To maintain the appearance of your vehicle’s interior
trim and top, follow these precautions:

Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
Improperly inflated tires are dangerous and can
cause accidents.
•Under inflation increases tire flexing and can
result in tire failure.
•Over inflation reduces a tire’s ability to cushion
shock. Objects on the road and chuck holes can cause
damage that results in tire failure.
•Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
•Overinflated or under inflated tires can affect
vehicle handling and can fail suddenly, resulting in
loss of vehicle control.
Always drive with each tire properly inflated.

An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchor positions directly behind
the child seat to secure a child restraint top tether
strap.
Children Too Large for Booster Seats
Children who are large enough to wear the shoulder belt
comfortably, and whose legs are long enough to bend
over the front of the seat when their back is against the
seat back should use the lap/shoulder belt in a rear seat.
•Make sure that the child is seated upright in the seat.
•The lap belt portion should be low on the hips and as
snug as possible.
•Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
•If the shoulder belt contacts the child’s face or neck,
move the child closer to the center of the vehicle.
Never allow a child to put the shoulder belt under an
arm or behind their back.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision.
Pets should be restrained in the rear seat in pet harnesses
or pet carriers that are secured by seat belts.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 43

Tilting the steering column while the vehicle is
moving is dangerous. Without a stable steering col-
umn, you could lose control of the vehicle and have
an accident. Adjust the column only while the ve-
hicle is stopped. Be sure it is locked before driving.

CAUTION!
Do not move your vehicle until the top has been
either fully attached to the windshield frame and
bodyside, or fully removed.

either fully attached to the windshield frame and
bodyside, or fully removed.

To use your brakes and decelerate more safely, follow these tips:
•Do not “ride” the brakes by resting your foot on the pedal. This
could overheat the brakes and result in unpredictable braking
action, longer stopping distances, or brake damage.
•When descending mountains or hills, repeated braking can cause
brake fade with loss of braking control. Avoid repeated heavy
braking by downshifting the transmission whenever possible.
•Do not downshift on icy or slippery roads, because engine braking
may cause skidding and loss of control.
•Engines may idle at higher speeds during warm-up, which could
cause rear wheels to spin and result in loss of vehicle control. Be
especially careful while driving on slippery roads, in close-quarter
maneuvering, parking or stopping. Remember, always engage
4-wheel drive when driving on slippery roads.
•Do not drive too fast for road conditions, especially when roads are wet
or slushy. A wedge of water can build up between the tire tread and the
road. This hydroplaning action can cause loss of traction, braking
ability, and control. Under such conditions, engage 4-wheel drive.
•After going through deep water or a car wash, brakes may become
wet, resulting in poor performance and unpredictable braking
action. Dry the brakes by gentle, intermittent pedal action while
driving at very slow speeds.
WARNING!
The weight and position of cargo and passengers can change
the vehicle center of gravity and vehicle handling. To avoid
loss of control resulting in personal injury, follow these
guidelines:
•Always place cargo evenly on the cargo floor, and locate
heavier objects as low and as far forward as possible.
•Place as much cargo as possible in front of the rear axle. Too
much weight or improperly placed weight over or behind
the rear axle can cause the rear of the vehicle to sway.
•Do not pile luggage or cargo higher than the top of the
seatback. This could impair visibility or become a danger-
ous projectile in a sudden stop or collision.
•The rear cargo space is intended for load carrying purposes
only, not for passengers, who should sit in seats and use
seat belts.
•On hardtop models, do not drive with the lift glass up. On
fabric top models, do not drive with the rear window
curtain up unless the side curtains are also open. This will
prevent dangerous exhaust fumes from entering the ve-
hicle.
