Cigarette lighter*
Switch on the ignition (page 39).1Cover plate
2Cigarette lighter
Open cover plate1 (page 319).
Push in cigarette lighter2.
The cigarette lighter will pop out auto-
matically when hot.
Take out cigarette lighter2.
Warning!G
Never touch the heating element or sides of
the cigarette lighter; they are extremely hot.
Hold the knob only.
Make sure that any children traveling with
you do injure themselves or start a fire with
the hot cigarette lighter.
When leaving the vehicle always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Unsupervised use of
vehicle equipment may cause an accident
and/or serious personal injury.
!The lighter socket can accommodate 12V
DC electrical accessories (up to a maximum of
85 W) designed for use with the standard “ciga-
rette lighter” plug type. Keep in mind, however,
that connecting accessories to the lighter socket
(for example extensive connecting and discon-
necting, or using plugs that do not fit properly)
can damage the lighter socket. With the socket
damaged, the lighter may no longer be able to be
placed in the heating (pushed-in) position, or the
lighter may pop out too early with the lighter not
hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12V DC elec-
trical accessories designed for use with the stan-
dard “cigarette lighter” plug type to the
12V power outlets (
page 322) in your vehicle
whenever possible.
!The cigarette lighter is not designed for use
with the electric air pump (
page 501). Use a
power outlet (
page 322) for electric air pump
operation.
iIf the engine is off, and the cigarette lighter
is being used extensively, the vehicle battery
may become discharged.

Driving instructions
High-performance brake system
(R 63 AMG only)
The high-performance brake system is
designed to operate under the extremely
high operating demands required to
accommodate the performance capabili-
ties of the vehicle. The brakes may
produce a squeaking-type noise depending
on the

vehicle speed

brake force applied

ambient conditions, e.g. temperature
and humidity
As with any brake system, the wear of indi-
vidual brake system components such as
brake pads or disks strongly depends on
your driving style and the conditions under
which you operate the vehicle. Thus, a driv-
ing style calling for high demand braking
will cause your vehicle’s brakes to wear
more quickly.Parking brake
When driving on wet roads or dirt covered
surfaces, road salt and/or dirt can get into
the parking brake. To prevent corrosion
and a reduction in the braking power of the
parking brake, observe the following:
From time to time, lightly engage the
parking brake before driving off.
Drive a distance of approximately
110 yds (100 m) at a maximum speed
of 12 mph (20 km/h)
Warning!G
New vehicle brake pads and discs, and
replacement brake pads and discs may take
several hundred miles of driving until they
provide optimum braking efficiency. Until
that time, you may need to use increased
brake pedal pressure while braking. Please
be aware of this and adjust your driving and
braking accordingly during this break-in
period.
Excessive high demand braking will cause
correspondingly high brake wear. Please be
attentive to the brake warning lamp in the
instrument cluster and brake condition mes-
sages in the multifunction display.
Especially for high performance driving, it is
important to maintain and have the brake
system checked regularly.
Warning!G
While performing this procedure, please as-
sure that the vehicle is stopped before ap-
plying the parking brake. Otherwise the rear
wheels could lock up. You could lose control
of the vehicle and cause an accident. In ad-
dition, the vehicle’s brake lights do not light
up when the parking brake is engaged.
Make sure not to endanger any other road
users when you engage the parking brake.
