Brake Wear
The brake pads have reached
their wear limit.
Have the brake pads replaced as soon as pos-
sible.
!
Brake pad thickness must be visually
checked by a qualified technician at the intervals
specified in the Maintenance Booklet.
Excessive load on the brake system causes in-
creased wear of brake pads and brake disks. If
the brake pads have to be replaced multiple
times within one maintenance service interval,
the brake disks must be checked. Observe the
information given in the Maintenance Booklet
and contact an authorized Mercedes-Benz
Center.
Warning!
G
Have brake pad replacement and other work
on the electro-hydraulic brake system car-
ried out by qualified technicians only. Con-
tact your Mercedes-Benz Center for further
information. The electro-hydraulic brake
system must be deactivated prior to working
on the system. High pressure is intermit-
tently built up in the system as part of its
automatic self-test. In addition, the system
is automatically activated when the vehicle
is unlocked by remote control, when the
driver or passenger door is opened, when
the SmartKey in the starter switch is turned
to position1, when the brake pedal is
depressed or when the parking brake is
released.
Failure to deactivate the system prior to
maintenance will cause brake pistons to
extend and brake fluid to leak, which may
result in injuries (contusions and acid
burns), see “Electro-hydraulic brake sys-
tem” (
page 87).

Replacing SmartKey batteries
Replacing SmartKey batteries
If the batteries in the SmartKey are
discharged, the vehicle can no longer be
locked or unlocked. It is recommended to
have the batteries replaced at an
authorized Mercedes-Benz Center.
Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
Replacement batteries: Lithium, type
CR 2025 or equivalent.
Remove the mechanical key out of the
SmartKey (
page 357).
Warning!
G
Batteries contain poisonous and corrosive
substances. Therefore keep the batteries
out of reach of children.
If a battery is swallowed, seek medical help
immediately.
Warning!
G
SmartKey batteries contain perchlorate ma-
terial, which may require special handling
and regard for the environment. Check with
your local government’s disposal guidelines.
California residents, see
www.dtsc.ca.gov/HazardousWaste/Per-
chlorate/index.cfm.
i
When inserting the batteries, make sure
they are clean and free of lint.
i
When replacing batteries, always replace
both batteries. The required replacement batter-
ies are available at any Mercedes-Benz Center.
