Maintenance
❈ The actual engine compartment in the vehicle may differ from the illustration.
❈ The battery is in the trunk.

The following lists are about the vehi-
cle inspection and maintenance that
should be performed by the owner or
an authorized EQUUS dealer, as
indicated. This will ensure your safety
and dependable driving.
Any adverse conditions should imme-
diately be checked by your EQUUS
dealer.
These Owner Maintenance Checklists
are mostly uncovered by your vehicle
warranties. Thus, you may charges
you for expenses of labor, parts or
lubricants.
Owner's maintenance sched-
ule
While refueling:
Check the engine oil level.
Check coolant level in coolantreservoir.
Check the windshield washer fluid level.
Check for any low or under-inflated tires.
While driving:
Check for any changes in theexhaust sounds or the smells.
Check for any steering wheel vibra- tion. Check whether you feel more
tightness or looseness of the steer-
ing wheel.
Check for any slight tilting, or “pulls” to one side, while driving on
a flat surface.
Check for any unusual sounds, tilt- ing, a braking distance, or “hard-to-
push” brake pedal while stopping.
Check the transmission fluid level upon experiencing a skid or a sud-
den transmission gear change.
Check the P(Park) function of the auto transmission.
Check the parking brake.
Check for any fluid leak (water dripping from the A/C while or after
the normal driving).
At least once a month:
Check the coolant level in theengine coolant reservoir.
Check the operation of all exterior lights, such as the stoplights, turn
signals and hazard warning flash-
ers.
Check the inflation pressures of all tires including the spare.

This may cause a skin burn or
other serious injuries.
