Multifunction steering wheel
The displays in the multifunction display 
and the settings in the control system are 
controlled by the buttons on the multifunc-
tion steering wheel.
Depending on the selected menu, pressing 
the buttons on the multifunction steering 
wheel will alter what appears in the multi-
function display.
The information available in the multifunc-
tion display are arranged in menus and 
accompanying functions or submenus.
The individual functions are then found 
within the relevant menu (radio or CD 
operations under 
AUDIO, for example). 
These functions serve to call up relevant 
information or to customize the settings 
for your vehicle.

It is helpful to think of the menus, and the 
functions within each menu, as being ar-
ranged in a circular pattern.
If you press buttonèorÿ re-
peatedly, you will pass through each 
menu one after the other.
If you press buttonjork re-
peatedly, you will pass through each 
function display, one after the other, in 
the current menu.
In the 
Settings menu, you will find a num-
ber of submenus instead of functions for 
calling up and changing settings. For in-
structions on using these submenus, see 
“Settings menu” (
page 136).
The number of menus available in the sys-
tem depends on which optional equipment 
is installed in your vehicle.
iThe headings used in the menus table are 
designed to facilitate navigation within the sys-
tem and are not necessarily identical to those 
shown in the control system displays.
The first function displayed in each menu will 
automatically show you which part of the system 
you are in.iSLK 55 AMG:
The steering wheel in this vehicle will vary from 
steering wheel shown. However, multifunction 
steering wheel symbols and feature description 
apply to AMG vehicles as well.

Warning!G
Driving when your engine is overheated 
can cause some fluids which may have 
leaked into the engine compartment to 
catch fire. You could be seriously 
burned.
Steam from an overheated engine can 
cause serious burns and can occur just 
by opening the hood. Stay away from 
the engine if you see or hear steam com-
ing from it.
Stop the vehicle in a safe location away from 
other traffic. Turn off the engine, get out of 
the vehicle and do not stand near the vehicle 
until the engine has cooled down.
