1 Vacuum pressure warning
NOTE:
The vacuum boost system is only installed on COE
40 and COE 45.
The vacuum pressure warning illuminates as a bulb
check when the ignition switch is turned to “ON.” It
goes out when the engine is started.
If illuminated while the engine is running, this light
warns that vacuum pressure has dropped below the
safe limit.
Braking efficiency is reduced in this situation.
Depress the brake pedal with full force to slow down
the vehicle as quickly as possible. Pull off the road
as soon as it is safe to do so, and perform the fol-
lowing checks:
1. Let the engine run at intermediate RPM until the
vacuum pressure warning goes out.
2. Check all air lines, hoses, and connections for
vacuum leaks.
3. If the light does not go out, or comes on again
soon after it has gone out, the vacuum system is
defective. Bring the vehicle to an authorized
Sterling service facility for repairs.
2 Brake warning
The brake warning illuminates as a bulb check
when the parking brake is set. With the ignition
switch “ON” and the engine not running, the brake
warning stays on even when the parking brake is
released. The light will go out when the engine is
started.
If this light illuminates while driving, the brake fluid
level has dropped below the safe limit. On COE 50,
the warning also illuminates, accompanied by a
buzzer, when the hydraulic fluid pressure is too low.
If the engine is running with the parking brake
released and the light does not go out, do not oper-
ate the vehicle. Pull off the road as soon as it is safe
to do so, and perform the following checks:
1. Check the brake fluid level.
Add more fluid if the level is too low.

WARNING
Do not operate the vehicle if the vacuum
pressure warning illuminates. Low vacuum
pressure reduces braking efficiency and
could cause an injury accident or loss of life.
WARNING
Do not continue to operate the vehicle if the
brake warning illuminates while driving. Low
brake fluid level and/or hydraulic pressure
reduces braking efficiency and could cause
an injury accident or loss of life.
