Limited braking performance on salt-

treated roads

If you drive on salted roads, a layer of salt

residue may form on the brake discs and

brake pads. This can result in a significantly

longer braking distance.

R

In order to prevent any salt build-up, apply

the brakes occasionally while paying atten-

tion to the traffic conditions.

R

Carefully depress the brake pedal and the

beginning and end of a journey.

R

Maintain a greater distance to the vehicle

ahead.

Servicing the brakes

!

If the red brake warning lamp lights up in

the instrument cluster and you hear a warn-

ing tone while the engine is running, the

brake fluid level may be too low. Observe

additional warning messages in the multi-

function display.

The brake fluid level may be too low due to

brake pad wear or leaking brake lines.

Have the brake system checked immedi-

ately. This work should be carried out at a

qualified specialist workshop.

!

Vehicles with 4MATIC: function or per-

formance tests may only be carried out on

a 2-axle dynamometer. If you are planning

to have the vehicle tested on such a dyna-

mometer, contact an authorized Mercedes-

Benz Center to obtain further information

first. Otherwise, you could damage the

drive train or the brake system.

Vehicles with 4MATIC: as the ESP

sys-

tem operates automatically, the engine and

the ignition must be switched off (Smart-

Key in position 0 or 1 in the ignition lock or

Start/Stop button in position 0 or 1) while

the parking brake is being tested on a brake

dynamometer.

system.

All checks and maintenance work on the

brake system must be carried out at a quali-

fied specialist workshop. Consult a qualified

specialist workshop to arrange this.

Have brake pads installed and brake fluid

replaced at a qualified specialist workshop.

If the brake system has only been subject to

moderate loads, you should test the function-

ality of your brakes at regular intervals. To do

so, press firmly on the brake pedal when driv-

ing at a high speed. This improves the grip of

the brake pads.

You can find a description of Brake Assist

(BAS) at (Y page 72) or of BAS PLUS with

Intersection Assist at (Y page 72).

The braking characteristics of the vehicle can

be seriously impaired if:

R

brake pads other than those recommended

are installed

R

the recommended brake fluid is not used

Safe braking can no longer be guaranteed.
