Compact Spare Tire
Although the compact spare was fully
inflated when your vehicle was new,
it
can lose air after a time. Check the
inflation pressure regularly. It should be
60 psi (420 1rPa). The compact spare is
made to
go up to 3,000 miles (5 000 km), ' so you can finish your trip and have
your full-size tire repaired or replaced
where you want. Of course, it's best to
replace your spare with a full-size tire as
soon as you can. Your spare will last
longer and be in
good shape in case you
need it again. Your anti-lock brake

Retractable Underhood Light
(OPTION)
To Use:
Pull the light away from the base and
attach it to the area
of the vehicle where
you
may be working. A magnet on the
back will hold it in place.

Engine Oil
It’s a good idea to check your engine oil
level every time you get fuel. In order to
get
an accurate reading, the oil must be
warm and the vehicle must be
on level
ground.
Turn off the engine and give the oil a
few minutes to drain back into the oil
pan. If you don’t, the oil dipstick might
not show the actual level.
To Check Engine Oil:
Pull out the dipstick and clean it with a
paper towel or cloth, then push it back
in all the way. Remove it again, keeping
the tip lower.

Windshield Washer Fluid (CONT.)
Brake Master Cylinder
Your brake master cylinder is here. It is
filled with DOT-3 brake fluid.
Your vehicle is equipped with either Standard Power Brakes or the Anti-
Lock Brake System.
There are only two reasons why the
brake fluid level in your master cylinder
might go down. The first
is that the
brake fluid goes down to an acceptable
level during normal brake lining wear.
When new linings are put in, the fluid
level goes back up. The other
reason is that fluid is leaking
out of the brake system. If it is, you
should have your brake system fixed, since a leak means that sooner or later
your brakes won’t work well, or won’t
work at all.
So, it isn’t a good idea to “top off’ your
brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when
your linings are worn, then you’ll have
too much fluid when you get new brake
linings. You should add (or remove)
brake fluid, as necessary, only when
work is done on the brake hydraulic
system.
