The interior light is activated for a short while when the SmartKey is removed from the igni-
tion lock. You can activate this delayed
switch-off using the on-board computer
(Y page 208). When a front door is opened, the front interior
lighting comes on. When a rear door is
opened, the rear interior lighting comes on. In addition, the courtesy lights come on.

is not in the ignition lock, the interior light- ing switches off after a short while.
Manual interior lighting control Front interior lighting
! If the interior lighting has been switched
on manually, it will not be switched off
automatically.
This can cause the starter battery to dis-
charge.
Make sure that the interior lighting does
not remain switched on too long after the
engine has been switched off. Front overhead control panel

WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tail-
gate/rear door is open when the engine is
running, particularly if the vehicle is moving,
exhaust fumes could enter the passenger
compartment. There is a risk of poisoning.
Turn off the engine before opening the tail-
gate/rear door. Never drive off with the tail-
gate/rear door open.
! Switch off the cargo compartment lamp if
you wish to leave the rear door open for a longer period. The battery may otherwise
discharge.
! Do not close the rear door while lock
:is
engaged at the bottom. Otherwise, you
could damage lock :. Front overhead control panel

Important safety notes
G
DANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop. G
WARNING
Bulbs, lamps and connectors can get very hot when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before changing a bulb.
Do not use a bulb that has been dropped or if
its glass tube has been scratched.
The bulb may explode if:
R you touch it
R it is hot
R you drop it
R you scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only install spare
bulbs of the same type and the specified volt- age.
Marks on the glass tube reduce the service
life of the bulbs. Do not touch the glass tube 108

Problems with the rear window
defroster
If the indicator lamp in the
ªrear window
defroster button flashes, the on-board volt-
age is too low. The rear window defroster has
deactivated prematurely or cannot be activa-
ted.
X Switch off any consumers that are not
required, e.g. reading lamps or interior
lighting.
When the battery is sufficiently charged,
the rear window defroster is activated
again automatically. Activating/deactivating air-recircula-
tion mode
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.

tion lock (Y page 133).

R after approximately 30 minutes at out-
side temperatures above approximately
41 ‡ (5 †) Activating/deactivating the residual
heat function
The "residual heat" function is only available
in Canada.
It is possible to make use of the residual heat
of the engine to continue heating the station- ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the coolant temperature and
on the interior temperature that has been set.
i The blower will run at a low speed regard-
less of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated.

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior. General notes
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air intake grill on the hood free of
blockages, such as ice, snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior.
i For virtually draft-free ventilation, adjust
the sliders of the air vents to the center
position.
i If the automatic climate control con-
stantly differs from the set temperature or
if undesired drafts are noticeable, proceed
as follows:
XOpen the side air vents
X Open the center air vents X
Open the rear air vents
X Set the temperature to 72 ‡ (22 †).

Important safety notes G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation. G
WARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
! Do not depress the accelerator when
starting the engine. Starting procedure X
Shift the automatic transmission to posi-
tion P.
The transmission position display in the
multifunction display shows P.
i For further information about the auto-
matic transmission, see (Y page 139).
i If you depress the brake when starting the
engine, pedal travel is unusually long and
there is less pedal resistance.
X Make sure that the parking brake is
applied.
X Turn the SmartKey to position 3in the igni-
tion lock (Y page 133) and release it as
soon as the engine is running.
i You can also use the touch-start function.
To do this, turn the SmartKey to position 3
(Y page 133) and release it immediately.
The engine then starts automatically. Pulling away
Automatic transmission G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
! Only shift the automatic transmission to
reverse gear Ror park position Pwhen the
vehicle is stationary. Otherwise, the auto-
matic transmission could be damaged.
! Do not depress the accelerator pedal
while depressing the brake pedal. This
impairs engine performance and results in
premature wear on the brake system and
drivetrain. 134

sage is shown in the AMG menu in the multi- function display.
i If you shift the transmission from
Rto D,
the ECO start/stop function is available
again once the ¤symbol reappears in
green in the multifunction display.
i The engine can be automatically switched
off an unlimited number of times.
i You can still activate the HOLD function
when the vehicle is stationary, even if the
engine has been switched off automati-
cally. It is then not necessary to continue
applying the brakes during the automatic
stop phase. When you depress the accel-
erator pedal, the engine starts automati-
cally and the braking effect of the HOLD
function is deactivated. Depress the accel-
erator pedal carefully, as the engine must
be started first.
i During automatic engine switch-off, the
climate control system only operates at a
reduced capacity. If you require full climate
control capacity, the ECO start/stop func-
tion can be deactivated by pressing the
ECO button (Y page 136). Automatic engine start The engine starts automatically if:
R In general:
- you switch off the ECO start/stop func-
tion by pressing the ECO button.
- you release the brakes when in transmis-
sion position Dor Nand when the HOLD
function is not active.
R By the driver:
- you release the brakes when in transmis-
sion position Dor N.
- you depress the accelerator pedal.
- you engage reverse gear R.
- you move the transmission out of posi-
tion P.
- you switch to drive program Sor M.
- you unfasten your seat belt or open the
