inlet grill).
The filter traps most
of the pollen from the air entering
the vehicle. Like your vehicle’s air filter, it may need to
be changed periodically. For information
on how often
to change the passenger compartment air filter, see
“Maintenance Schedule” in the Index.

Turn off the ignition while the wipers are at the
outer positions of the wiper pattern. The blades are
more accessible for removal/replacement while
in
this position.
Pull the windshield wiper arm
3 to 4 inches
(7.5 to 10 cm) away from the windshield.
While holding the wiper arm away from
the glass,
push the release clip from under the blade
connecting point and pull
the blade assembly down
toward the glass to remove it from
the wiper arm.
Push the new wiper blade securely
on the wiper arm
until
you hear the release clip “click” into place.
For wiper blade replacement length and type, also see
“Capacities and Specifications”
in the Index.
Tires
Your new Buick comes with high-quality tires made by
a leading tire manufacturer.
If you ever have questions
about your tire warranty and where
to obtain service, see
your Buick Warranty booklet for details.
Pol .y maintained and improperly used tires
are dangerous.

Overloading your tires can cause
overheating as
a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle” in
the Index. Underinflated tires pose the same danger as
overloaded tires. The resulting accident could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked when your tires are cold.
Overinflated tires are more likely to be
cut, punctured
or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
