Notes:
When in operation, the seat heater consumes a large 
amount of electrical power. It is not advisable to use the 
seat heater longer than necessary.
The seat heaters may automatically switch off if too 
many power consumers are switched on at the same 
time, or if the battery charge is low. When this occurs, 
the indicator lamp in the switch will blink (both 
indicator lamps blink during rapid seat heating mode). 
The seat heaters will switch on again automatically as 
soon as sufficient voltage is available.
If the blinking of the indicator lamps is distracting to 
you, the seat heaters can be switched off.

%Left mirror
&Right mirror
To adjust, toggle the switch forward, backward or to 
either side.With the electronic key in steering lock position 2, the 
driver’s side mirror reflection brightness responds to 
changes in light sensitivity.
With gear selector lever in position “R”, or with the 
interior lamp switched on, the driver’s side mirror 
brightness does not respond to changes in light 
sensitivity.
Notes:
The exterior mirrors have electrically heated glass. The 
heater switches on automatically, depending on outside 
temperature.
If an exterior mirror housing is forcibly pivoted from its 
normal position, it must be repositioned by applying 
firm pressure until it snaps into place.
Wa r n i n g !
Exercise care when using the passenger-side 
mirror. The passenger-side exterior mirror is 
convex (outwardly curved surface for a wider field 
of view). Objects in mirror are closer than they 
appear. Check your inside rear view mirror or 
glance over your shoulder before changing lanes.

Starting and turning off the engine
Before starting
Ensure that parking brake is engaged and that selector 
lever is in position “P” or “N”. Turn electronic key in 
steering lock to position 2.
Starting
Do not depress accelerator.
Briefly turn electronic key in steering lock clockwise to 
the stop and release. The starter will engage until the 
engine is running.
If engine will not run, and the starting procedure stops, 
turn electronic key completely to the left and repeat 
starting the engine.
After several unsuccessful attempts, have the system 
checked at the nearest authorized Mercedes-Benz 
Center.Important!
Due to the installed starter non-repeat feature, the 
electronic key must be turned completely to the left 
before attempting to start the engine again.
In areas where temperatures frequently drop below -4°F 
(-20°C) we recommend that an engine block heater be 
installed. Your authorized Mercedes-Benz Center will 
advise you on this subject.
Turning off
Turn the electronic key in the steering lock to position 0 
to stop the engine.
The electronic key can only be removed with the 
selector lever in position “P”.
