2016 MERCEDES-BENZ S CLASS warning

There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt
before starting the engine.
G WARNING
If the head restraints are not installed or not
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the
event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
General notes Pay attention to the important safety notes
( Y
page 105).
Do not rotate the head restraints of the front and
rear seats. Otherwise, you cannot adjust the
height and angle of the head restraints to the
correct position.

Problems with the seat ventilation Problem
Possible causes/consequences and P Solutions
The seat ventilation has
switched off prematurely
or cannot be switched
on. The on-board voltage is too low because too many electrical consum-
ers are switched on. X
Switch off electrical consumers that you do not need, such as the
rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat ventilation can be
switched back on.

G WARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.

tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.

Canada only:
The daytime running lamps improve the visibility
of your vehicle during the day. The daytime run-
ning lamps function is required by law in Can-
ada. It cannot therefore be deactivated.
When the engine is running and the vehicle is
stationary: if you move the selector lever from a
drive position to P , the daytime running lamps/
low-beam headlamps go out after three
minutes.
When the engine is running, the vehicle is sta-
tionary and in bright ambient light: if you turn the
light switch to the ` position, the daytime
running lamps and parking lamps switch on.

Problems with "Pre-entry climate control via SmartKey" Problem
Possible causes/consequences and P Solutions
"Pre-entry climate con-
trol via SmartKey" can-
not be switched on or
has switched itself off. The condition of charge of the high-voltage battery is under the speci-
fied minimum condition of charge. X
Start the engine when the vehicle is at a standstill.
The engine powers the electric motor. The electric motor operates
as a generator. The high-voltage battery is being charged.
Further information on charging the high-voltage battery via: R
a mains socket ( Y
page 183)R
a charging station ( Y
page 186)R
a wallbox ( Y
page 185)
"Pre-entry climate control via SmartKey" has been started more than
twice with the engine switched off. X
Switch on the engine and let it run for more than ten seconds. X
Try again to switch on "Pre-entry climate control via SmartKey".
Pre-entry climate control at time of
departure
Important safety notes
G WARNING
If persons, particularly children are subjected
to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
General notes The "Pre-entry climate control at departure
time" function is only available in PLUG-IN
HYBRID vehicles.
You can use the "Pre-entry climate control at
departure time" function to cool or heat the
vehicle interior if the engine is not running.
The "Pre-entry climate control at departure
time" function can be activated regardless of
whether or not the vehicle is connected to an
electric power supply. The condition of charge of
the high-voltage battery must be higher than the
specified minimum condition of charge, how-
ever.
When the vehicle is connected to an electric
power supply, priority is given to charging the
high-voltage battery to the specified minimum charge. "Pre-entry climate control at departure
time" is only activated subsequently.
The running time of the "Pre-entry climate con-
trol at departure time" function may be reduced
if: R
the vehicle is not connected to an electric
power supply and R
the high-voltage battery is not fully charged
With active "Pre-entry climate control at depar-
ture time" the condition of charge of the high-
voltage battery can be reduced, even if the
charge cable connector is connected.
When the vehicle is cooled, the following func-
tions are activated if required: R
