Driving instructions
To help prevent brake disk corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes.
Refer to the description of the Brake Assist
System (BAS) (
୴ page 83).
If the parking brake is released and the red
brake warning lamp in the instrument clus-
ter stays on, there is a malfunction in the
electro-hydraulic brake system
(
୴ page 303) or 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.
The brake fluid level in the reservoir may
be too low if the brake warning lamp in the
instrument cluster comes on and a warn-
ing sounds although the parking brake is
released (
୴ page 303). Observe additional
messages that may appear in the
multifunction display (
୴ page 330).
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.

Because the ESP

operates automatically,
the engine must be shut off (SmartKey in starter
switch position 0 or 1) when
ț the parking brake is being tested on a brake
test dynamometer
ț the vehicle is towed with the front axle raised
Active braking action through the ESP

may
otherwise seriously damage the brake system
which is not covered by the Mercedes-Benz

The brake system is designed to decelerate
your SLR from high speeds at the best possible
rate. Depending on the applied brake force,
speed, and ambient conditions, the brake sys-
tem may produce a squeak-type noise when you
apply the brakes at a moderate rate, e.g. at city
traffic. If you experience this noise, you should
occasionally test the effectiveness of the brakes
by applying above-normal braking pressure at
high speeds. Please perform this braking proce-
dure three times. This will also enhance the grip
of the brake pads. If the noise continuous,
contact an authorized Mercedes-Benz Center.
Warning! G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
