Do not start your vehicle in a closed
garage or in other enclosed areas. Exhaust
fumes can be toxic. Always open the

TAPPET NOISE
[TO08400( M)01/96]
It is normal for the oil to drain down from the
hydraulic tappets in your engine during
extended shutdown periods (overnight). As a
result, these tappets may clatter for a few
seconds after the engine starts until oil pressure
builds up. This momentary start-up noise is
normal and is not harmful to engine operation.

Front Disc Brakes
*
[GF01000( M)01/96]
The front disc brakes are self-adjusting. They do
not require service other than periodic
lubrication of the caliper slide rails and
inspection for pad wear.

Hydraulic Power Brakes
[GF01450( M)01/96]
The hydraulic brake system is made up of two
independent hydraulic circuits. One hydraulic
circuit supplies fluid to the front disc brakes and
the other hydraulic circuit supplies fluid to the
rear disc brakes. These two circuits are supplied
by a common hydraulic brake fluid reservoir,
with a fluid level sensor.

seems ªlowº, it may indicate the need for a
brake system inspection and/or service. You
should have your brakes checked as soon as
possible.
*
[GF03100( ALL)01/96]
Occasional brake squeal during light to moderate
stops does not affect the function of the brake
system and is normal. However, if the squeal
becomes annoyingly loud or increases
significantly in frequency of occurrence, return
the vehicle to your dealer for inspection.
