Brake Pad Wear Indicator Lamp; Brake Fluid; Charge Indicator Lamp; Oil Pressure Gauge - Mercedes-Benz 280 E 1981 Owner's Manual

A leak or brake pad wear may cause
a shortage of brake fluid in the re­
servoir.
Have brake system checked in a
MERCEDES-BENZ service station as
soon as possible.
Install only brake pads recomm end­
ed by us.
If other than recommended brake
pads are installed, the braking pro­
perties of the vehicle can be affected
to an extent that the safety is sub­
stantially impaired.

Brake Pad Wear Indicator Lamp

The brake pad wear indicator lamp
in the instrument cluster comes on
when the key in the steering lock is
turned to driving position " 2" and it
must go out when the engine is
running. If the indicator lamp lights
up during braking or driving, this
shows that the front wheel brake
pads are worn down.
Have brake system checked in a
MERCEDES-BENZ service station as
soon as possible.

Brake Fluid

During the course of the operation
of the vehicle, the boiling point of
the brake fluid is continuously being
reduced through the absorption of
m oisture from the atmosphere. Un­
der extremely hard operating co nd i­
tions, this m oisture content can lead
to the form ation of vapor in the sy­
stem thus reducing the system's e ffi­
ciency. The brake fluid must therefo­
re be replaced annually, preferably
in the spring. It is recommended to
use only brake fluid approved by
MERCEDES-BENZ.
Your MERCEDES-BENZ dealer w ill
provide you with additional inform a­
tion.

Charge Indicator Lamp

Should the charge indicator lamp
fail to come on p rio rto starting
when the ignition key is in position
" 2" or should it fail to go out after
starting or during operation, this in­
dicates a fault which must be repai­
red at a MERCEDES-BENZ service
station as soon as possible.
Safe Driving

Oil Pressure Gauge

The oil pressure may drop at idle
speed to 0.5 bar/7.1 psi if the engine
is at operating temperature. This w ill
not jeopardize its operational relia­
bility. Pressure must, however, rise
immediately upon acceleration.
The oil pressure gauge does not
provide any inform ation concerning
the oil level in the engine.

Coolant Temperature Gauge

Due to the pressurized cooling sy­
stem, the coolant only starts boiling
at a temperature of approx. 125°C/
257° F with an antifreeze-blended
coolant fill protecting down to
- 3 0 ° C / —22° F (see also " Fuels,
Coolants, Lubricants, etc." ).
During severe operating conditions
and stop-and-go city traffic the coo­
lant temperature must not rise above
the red marking.
