PLUG-IN HYBRID vehicles:
You are exiting the vehicle when it is in a ready-to-drive state. The
READY indicator in the multifunction display is on. A warning tone also
sounds.
If you leave the vehicle:
XSecure the vehicle against rolling away (Ypage 178).
XSwitch off the ignition and remove the SmartKey.
If you do not leave the vehicle:
XSwitch off the electrical consumers, e.g. automatic climate control,
seat heating.
Please note the following: the electrical consumers are supplied by the 12 V battery. If the vehicle is left in a ready-to-drive state for an exten-
ded period, it will switch off once the 12 V battery is almost empty. It
will then only be possible to start the vehicle using a second battery
(jump-starting).

PLUG-IN HYBRID vehicles:
You have attempted to change the operating mode when in automatic
drive program Sport, Individual (with activated Sport characteristics)
or manual drive program M.
XSelect the Comfort, Slippery or Individual (with activated Comfort or
Eco characteristics) drive program (Ypage 152).
XSelect the preferred operating mode HYBRID,E-MODE,E-SAVE or
CHARGE (Ypage 246).
E-MODE CurrentlyUnavailable
PLUG-IN HYBRID vehicles:
The condition of charge of the high-voltage battery has dropped to the
lower limit and the E-MODEoperating mode has been switched off.
Driving with the internal combustion engine is activated and the oper-
ating mode switches to the basic HYBRIDsetting.
XContinue driving using the internal combustion engine.
You can switch to the E-SAVEorCHARGE operating mode as
required (

;NThe yellow Check Engine warning lamp lights up while the engine is running.
There may be a malfunction, for example:
Rin the engine management
Rin the fuel injection system
Rin the exhaust system
Rin the ignition system (for vehicles with gasoline engines)
Rin the fuel system
The emission limit values may be exceeded and the engine may be in emergency
mode.
XVisit a qualified specialist workshop immediately.
Vehicles with a diesel engine: the fuel tank has been run dry (
Ypage 166).
XStart the engine three to four times after refueling.
If the yellow Check Engine warning lamp goes out, emergency running mode is
canceled. The vehicle need not be checked.
In some states, you must immediately visit a qualified specialist workshop as soon
as the yellow Check Engine warning lamp lights up. This is due to the legal require-
ments in effect in these states. If in doubt, check whether such legal regulations
apply in the state in which you are currently driving.
