Instruments and warning lamps
1 Low vacuum warning lamp
<Other than FE85>
WARNING
Braking is dangerously sluggish when the
vacuum warning lamp is illuminated. For
safety, never drive with the vehicle in this
condition.
Z10909
This lamp illuminates when the starter switch is
turned to the "ON" position. As long as the lamp
goes out when the engine is started, the vehicle
may be driven. If illuminated while the engine is run-
ning, this lamp signals that the vacuum level in the
brake vacuum tank has dropped below the safe
limit.
This lamp, when illuminated, signals that the vac-
uum level in the brake vacuum tank has dropped
below the safe limit.
Since braking becomes sluggish under this condi-
tion, depress the brake pedal with full force to slow
down the vehicle, then pull off the road as soon as it
is safe to do so, and perform the following checks:
1. Let the engine run at intermediate RPM until the
warning lamp goes out.
2. Check piping and its connections for vacuum
leaks.
3. If the lamp does not go out or comes on again
soon after it has gone out, the vacuum system is
defective and must be repaired. Call an autho-
rized dealer.

2 Brake warning lamp

WARNING
If the brake warning lamp comes on owing to
an excessively low level of brake fluid (or low
power steering fluid pressure on FE85), the
brakes will not be fully effective and driving
will thus be dangerous. Do not drive the vehi-
cle in this condition.
Z10908
This lamp lights up when the parking brake lever is
pulled, when the brake fluid level drops below the
safe limit, or when the power steering fluid pressure
is too low on FE85. When the power steering fluid
pressure is too low on FE85, illumination of the
lamp is accompanied by sounding of a buzzer. The
buzzer stops when the parking brake is applied.
Should the lamp remain illuminated even after the
parking brake lever has been released or light up
during driving, pull off the road as soon as it is safe
to do so, and perform the checks below.
