Safe Driving
applying brakes for about 10 seconds
while pulling release knob out, then
release parking brake completely.
This practice will keep the parking
brake at maximum efficiency.
Warning:
The stop lamps will not come on when
applying the parking brake only. Apply
parking brake only when road behind
vehicle is clear of traffic.
All checks and maintenance work on
the brake system should be carried
out by a MERCEDES-BENZ dealer.
If the parking brake is released and
the brake warning lamp in the
instrument cluster comes on, the
brake fluid level in the reservoir is too
low.
Brake pad wear or a leak in the
system may be the reason for low
brake fluid in the reservoir.
Have the brake system inspected at
an authorized MERCEDES-BENZ
dealer without delay.
Install only brake pads recommended
by us. If other than recommended
brake pads are installed, the braking
properties of the vehicle can be
affected to an extent that the safety is
substantially impaired.
Brake Pad Wear Indicator Lamp
The brake pad wear indicator lamp in
the instrument cluster stays on when
the key in the steering lock is turned
to position “ 2” and it must go out
when the engine is running. If the indi­
cator lamp lights up during braking,
this shows that the front wheel brake
pads are worn.
Have the brake system checked at an
authorized MERCEDES-BENZ dealer
as soon as possible.
Brake Fluid
Brake fluid should be changed once a
year, preferably in spring.
Only use brake fluid recommended by
us. For further information, refer to
“ Fuels, Coolants, Lubricants, etc.’’.
The low brake fluid indicator lamp will
come on if insufficient brake fluid is in
the reservoir. (The key must be in
steering lock position “ 2” , and the
parking brake released.)
When the minimum mark on the
reservoir is reached, have the system
checked (brake lining thickness,
leaks).
Charge Indicator Lamp
Should the charge indicator lamp fail
to come on prior to starting when the
key is in steering lock position “ 2” or
should it fail to go out after starting or
during operation, this indicates a fault
which must be repaired at an author­
ized MERCEDES-BENZ dealer as
soon as possible.
When the charging indicator lamp
glows while the engine is running, the
V-belts may be lose or broken (which
also makes the water pump inopera­
tive). This may cause overheating and
damage to the engine. In this case the
V-belts must be tightened or replaced
at once.
Fuel Reserve Warning Lamp
The fuel reserve warning lamp will
come on when the key in the steering
lock is turned to position “ 2", and will
go out after the engine is running.
If the warning lamp stays on after the
engine starts, or comes on while
driving, it indicates that the fuel level
is down to the reserve quantity.
