Important safety notes
GWARNING
If you operate information systems and
communication equipment integrated in
the vehicle while driving, you will be dis- tracted from traffic conditions. You could
also lose control of the vehicle. There is a
risk of an accident.
Only operate the equipment when the traf-
fic situation permits. If you are not sure
that this is possible, park the vehicle pay-
ing attention to traffic conditions and
operate the equipment when the vehicle is
stationary.
You must observe the legal requirements for
the country in which you are currently driv-
ing when operating the on-board computer.
GWARNING
If the instrument cluster has failed or mal- functioned, you may not recognize function
restrictions in systems relevant to safety.
The operating safety of your vehicle may beimpaired. There is a risk of an accident.
Drive on carefully. Have the vehicle
checked at a qualified specialist workshop
immediately.
The on-board computer only shows display
messages and/or warnings from certain sys-
tems in the display. You should therefore
make sure your vehicle is operating safely at all times. Otherwise, you may cause an acci-
dent by driving a vehicle that is not operat-
ing reliably.
If the operating safety of your vehicle
impaired, park the vehicle as soon as possi-
ble paying attention to road and traffic con-
ditions. Contact a qualified specialist work-
shop.
Read and follow the notes in the overview of
warning and indicator lamps in the instru-
ment cluster (
Ypage 24).
Displays and operation
Instrument cluster lighting
Instrument cluster lighting includes illumi-
nation of the instrument cluster, the addi-
tional instruments on the dashboard, the dis-
plays and the controls.
The instrument cluster lighting is switched
automatically between day and night lighting
depending on the ambient light conditions
(
Ypage 67).
You can additionally set the brightness of the
instrument cluster lighting to different lev-
els in the on-board computer (
Ypage 115).
Speedometer
If you turn the key to position 2in the igni-
tion lock, the warning and indicator lamps in
the instrument cluster will briefly light up
for a lamp test. During the lamp test, the
illuminated speedometer needle moves in the
speedometer.
The display can show a digital speedometer.
The digital speedometer can be hidden/
displayed and its speed unit selected
(
Ypage 115).

You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the temperature measured
and does not record the road temperature.
The outside temperature is displayed on the

Dashboard instruments
!Do not drive in the overrevving range, as
this could damage the engine.
HEnvironmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consump-
tion of your vehicle and harms the envi-
ronment as a result of increased emissions.
The overrevving range of the engine is shown with dashed lines in the orange marking of
rev counter 0043. The fuel supply is interrupted
to protect the engine when the overrevving
range is reached.
Dashboard clock 0044is synchronized with the
clock in the on-board computer.
Rev counter 0043, together with dashboard
clock 0044, can be rotated approximately 60° on
the dashboard.

Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if you replace it with a fuse with a higher
amperage, the electric cables could be
overloaded. This could result in a fire.
There is a risk of an accident and injury.
Always replace faulty fuses with the speci-
fied new fuses having the correct amper-
age.
!Only use fuses that have been approved for
smart vehicles and which have the correct
fuse rating for the system concerned. Oth-
erwise, components or systems could be
damaged.
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the com-
ponents on the circuit and their functions
stop operating.
Blown fuses must be replaced with fuses of the
same rating, which you can recognize by the
color and value. The fuse ratings are listed in
the fuse allocation chart (
Ypage 175).
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
Before changing a fuse
XSecure the vehicle against rolling away
(Ypage 100).
XSwitch off all electrical consumers.
XTurn the key to position 0in the ignition
lock and remove it (Ypage 87). All indica-
tor lamps in the instrument cluster must be off.
The fuses are located in various fuse boxes:
RFuse box in the front area
RFuse box in the glove compartment
Fuse box in the front area
Pay attention to the "Important safety notes"
(Ypage 173).
GWARNING
If the windshield wipers begin to operate
while the service cover is open, there is a
danger of injury from the wiper arms. There
is a risk of injury.
Always switch off the windshield wipers
and the ignition before opening the ser-
vice cover.
!Make sure that no moisture can enter the
fuse box when the cover is open.
!When closing the cover, make sure that it
is lying correctly on the fuse box. Moisture
seeping in or dirt could otherwise impair
the operation of the fuses.
XMake sure that the windshield wipers are
turned off.
XOpen the service cover (Ypage 151).
You can now see fuse box 0043.
