2014 MERCEDES-BENZ S-Class Fluid

!
Vehicles with 4MATIC: function or
performance tests may only be carried out
on a 2-axle dynamometer. If you wish to
operate the vehicle on such a
dynamometer, please consult an
authorized Mercedes-Benz Center in
advance. You could otherwise damage the
drive train or the brake system.
! Vehicles with 4MATIC: the ESP®
system
operates automatically. The engine and the
ignition must therefore be switched off (the
SmartKey must be in position 0or 1in the
ignition lock or the Start/Stop button must
be in position 0or 1) if the electric parking
brake is tested on a brake dynamometer.
Braking triggered automatically by ESP ®
may cause severe damage to the brake
system.
! Vehicles without 4MATIC: the ESP®
system operates automatically. The engine
and the ignition must therefore be switched
off (the SmartKey must be in position 0or
1 in the ignition lock or the Start/Stop
button must be in position 0or 1) if:
R the electric parking brake is tested using
a brake dynamometer.
R the vehicle is towed with one axle raised.
Braking triggered automatically by ESP ®
may cause severe damage to the brake
system.
All checks and maintenance work on the
brake system must be carried out at a
qualified 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
functionality of your brakes at regular
intervals.
Information on BAS (Brake Assist)
(Y page 71) and BAS PLUS (Brake Assist
PLUS) (Y page 72). For safety reasons, Mercedes-Benz
recommends only installing the following
brake disks and brake pads/linings:
R
brake disks that have been approved by
Mercedes-Benz
R brake pads/linings that have been
approved by Mercedes-Benz or that are of
an equivalent standard of quality
Other brake disks or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake disks and brake
pads/linings on an axle at the same time.
Always install new brake pads/linings when
replacing brake disks.
The vehicle is equipped with lightweight
brake disks to which the wheel assembly with
rim and threaded connection is matched.
The use of brake disks other than those
approved by Mercedes-Benz can change the
track width and is subject to approval, if
applicable.
Shock-type loads when handling the brake
disks, such as when changing wheels, can
lead to a reduction in comfort when driving
with lightweight brake disks. Avoid shock-
type loads on the lightweight brake disks,
particularly on the brake plate.
Mercedes-Benz recommends that you only
use brake fluid that has been specially
approved for your vehicle by Mercedes-Benz,
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
affect your vehicle's operating safety.

compartment, such as the engine, radiator
and parts of the exhaust system, can become
very hot. Working in the engine compartment
poses a risk of injury.
Where possible, let the engine cool down and
touch only the components described in the
following. G
WARNING
The engine cooling system is pressurized,
particularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape. X
Park the vehicle on a level surface.
Only check the coolant level when the
vehicle is on a level surface and the engine
has cooled down.
X Turn the SmartKey to position 2in the
ignition lock (Y page 171).
or
X Press Start/Stop button twice
