1 Vacuum pressure warning lamp

WARNING
Braking is dangerously sluggish when the
vacuum warning lamp is illuminated. For
safety, never drive with the vehicle in this
condition.
This lamp illuminates when the starter switch is
Z10909
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.
