light operation while you activate the brake pedal
and switches involved. Have any malfunctions cor-
rected for your benefit and for the benefit of other
drivers too.
Headlamp aim should also be checked periodically.
Frequent signaling by oncoming motorists when you
are using your low beams is a good indication that
headlamps are aimed too high. Likewise, poor visibil-
ity when driving On a dark road may indicate improper
aim. Have your dealer or a qualified service station
check headlamp aim at least once a year and be sure
to have replacement units aimed properly at time of
installation or following a front- end collision.
STEERING
,
On vehicles equipped with power steering, the power
assist is provided by a hydraulic pump driven by the
engine.
When the engine is not running, or if the
power steering pump drive belt should break, there
is no power assistj therefore, much greater steering
effort will be required. A loud squealing noise when
making a full right or left turn is usually an indication
of improper belt tension. The pump belt, as well as
the other engine drive belts, should be checked peri-
odically and adjusted or replaced as necessary.
Power steering lines and hoses should be checked for
leaks, deterioration and chafing at every oil change.
The power steering pump fluid level should also be
checked at the same interval. In addition, your ser-
viceman should be asked to visually check the con-
dition of all steering linkage whenever your vehicle
is raised for lubrication or oil change service. This
should include an inspection of the pitman shaft, tie
A3
rod, idler arm, and steering arm attachments. Needed
adjustments or replacements should be made promptly.
OTHER FEATURES
Many features provided for safety of vehicle operation
could become ineffective because of wear, misalign-
ment or misadjustment occurring during normal use
as a result of misuse or abuse. Periodically, the driver
should check performance of these features, as listed
below, to determine that they are performing properly,
or if repairs or adjustments are needed.
On Vehicles Equipped with Anti-Theft Lock-Check
that it will lock in only the PARK position (REVERSE
on manual transmission vehicles) by attempting to
turn key to LOCK in some other transmission selec-
tor position, with vehicle stationary.
Seat Belts-Lap belts and also shoulder belts
(if
so
equipped), as well as buckles, retractors and anchors,
should be checked for loose connections, damage and
proper latching action. Any questionable parts should
be replaced.
Windshield Wipers and Washers- Continued good
windshield wiper and washer performance is impor-
tant to good driver vision. Drivers should check per-
formance of both systems, particularly in regard to the
condition and alignment of wiper blades, and the
amount and direction of fluid sprayed by the washers.
Blades should be replaced and wipers and /or washers
should be serviced whenever vision is impaired.
Defrosters-Defroster performance could be adversely
affected by malfunctions in the heater /defroster wir-
ing or air distribution systems which develop during
