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.

the front or rear axle raised (not permit-

ted for vehicles with 4MATIC).

ality of your brakes at regular intervals. To do

so, press firmly on the brake pedal when driv-

use brake fluid that has been specially

or which corresponds to an equivalent quality

standard. Brake fluid which has not been

approved for Mercedes-Benz vehicles or

which is not of an equivalent quality could

Parking brake

WARNING

If you must brake the vehicle with the parking

brake, the braking distance is considerably

longer and the wheels could lock. There is an

increased danger of skidding and accidents.
Only use the parking brake to brake the vehi-

cle when the service brake is faulty. Do not

apply the parking brake too firmly. If the

wheels lock, release the parking brake until

the wheels begin turning again.

If you brake the vehicle with the parking

brake, the brake lamps will not light up.
If you drive on wet roads or dirt-covered sur-

faces, road salt and/or dirt could get into the

parking brake.
In order to prevent corrosion and a reduction

in the braking power of the parking brake,

observe the following:

gently depress the parking brake from time

to time before beginning the journey.

Drive for approximately 110 yds (100 m) at

a maximum speed of 12 mph (20 km/h).
