increased braking distance, which could
lead to an accident.
To avoid this danger, you should:
R
occasionally brake carefully when you
are driving on salt-covered roads, so that
any layer of salt that may have built up
on the brake discs and the brake linings
is removed without putting other road
users at risk
R
maintain a greater distance to the vehicle
ahead and drive with particular care
R
carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are
removed from the brake disc
Brake service
!
The brake fluid level in the reservoir may
be too low if the brake warning lamp in the
instrument cluster comes on and an
acoustic warning sounds although the
parking brake is released. Observe
additional messages in the multifunction
display that may appear.
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
immediately. Contact an authorized
Mercedes-Benz Center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Center.
Only install brake pads and use brake fluid
recommended by Mercedes-Benz.
G
Warning!
If other than recommended brake pads are
installed, or other than recommended
brake fluid is used, the braking properties
of the vehicle can be degraded to an extent
that safe braking is substantially impaired.
This could result in an accident.
! Only conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz Center. You could
otherwise seriously damage the brake
system or the transfer case which is not
covered by the Mercedes-Benz Limited
Warranty.
!
Because the ESP
®
operates
automatically, the engine and ignition must
be shut off (SmartKey in starter switch
position
0 or 1 or KEYLESS-GO start/stop
button in position 0 or 1) when the parking
brake is being tested on a brake test
dynamometer. Such testing should be no
longer than 10 seconds.
Active braking action through the ESP
®
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
If your brake system is normally only
subjected to moderate loads, you should
occasionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads.
G
Warning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Refer to the description of the Brake Assist
System (BAS) (
Y
page 77).
