parking brake is being tested on a brake dyna-
mometer (maximum 10 seconds).
Braking triggered automatically by ESP
seriously damage the brake system.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
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 functional-
ity of your brakes at regular intervals. To do so,
depress the brake pedal firmly when driving at a
high speed. This improves the grip of the brake
pads.

Mercedes-Benz recommends that you only have
brake pads/linings installed on your vehicle
which have been approved for Mercedes-Benz
vehicles or which correspond to an equivalent
quality standard. Brake pads/linings which have
not been approved for Mercedes-Benz vehicles
or which are not of an equivalent quality could
affect your vehicle's operating safety.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for

fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth on
the road surface, there is a danger of hydro-
planing occurring, even if:
you drive at low speeds.
R
the tires have adequate tread depth.
R
For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
lower your speed.
R
avoid ruts.
R
avoid sudden steering movements.
R
brake carefully.

Driving on flooded roads

!
Do not drive through flooded areas. Check
®
may
the depth of any water before driving through
it. Drive slowly through standing water. Oth-
erwise, water may enter the vehicle interior or
the engine compartment. This can damage
the electronic components in the engine or
the automatic transmission. Water can also
be drawn in by the engine's air suction nozzles
and this can cause engine damage.
i
Vehicles with the AIRMATIC package:
select the raised vehicle level before driving
through a body of water.
Off-road fording
page 67).
Y !
Under no circumstances should you accel-
erate before entering the water. The bow
wave could cause water to enter and damage
the engine and other assemblies.
!
Do not open any of the vehicle's doors while
fording. Otherwise, water could get into the
vehicle interior and damage the vehicle's
electronics and interior equipment.
Establish how deep the water is and the char-
R
acteristics of the body of water before ford-
ing.
Select the highest possible vehicle level.
R
Shift to a lower gear using the left-hand steer-
R
ing wheel paddle shifter.
Avoid high engine speeds.
R
Enter and exit the water at a flat place and at
R
a steady walking pace.
Drive slowly and at an even speed through the
R
water.
Ensure that a bow wave does not form as you
R
drive.
Do not stop and do not switch off the engine.
R
Water offers a high degree of resistance, and
the ground is slippery and in some cases
unstable. Therefore, it is difficult and danger-
ous to pull away in the water.
Clean any mud from the tire tread after ford-
R
ing.
Apply the brakes to dry them after fording.
R
Always observe the fording depth values
( page 359).
