The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.

With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.Activating

authorized Mercedes-Benz Light Truck Center.
iHow long the system will provide heating
depends on

the coolant temperature

the battery voltage
Regardless of the temperature and air volume
set on the climate control panel, the interior tem-
perature is set to 72°F (22°C) and the blower
runs on low speed to protect the vehicle battery.
iThe residual heat is automatically turned off:

when the ignition is switched on

after about 30 minutes

if the coolant temperature is too low

if the battery voltage drops

Cigarette lighter*
Switch on the ignition (page 42).1Cigarette lighter
Open the ashtray (page 323).
Push in cigarette lighter1.
The cigarette lighter will pop out auto-
matically when hot.
Warning!G
Never touch the heating element or sides of
the cigarette lighter; they are extremely hot.
Hold the knob only.
Make sure that any children traveling with
you do not injure themselves or start a fire
with the hot cigarette lighter.
When leaving the vehicle always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised
access to a vehicle could result in an
accident and/or serious personal injury.
!The lighter socket can accommodate
12V DC electrical accessories (up to a maximum
of 180 W) designed for use with the standard
“cigarette lighter” plug type. Keep in mind, how-
ever, that connecting accessories to the lighter
socket (for example extensive connecting and
disconnecting, or using plugs that do not fit prop-
erly) can damage the lighter socket. With the
socket damaged, the lighter may no longer be
able to be placed in the heating (pushed-in) posi-
tion, or the lighter may pop out too early with the
lighter not hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12V DC elec-
trical accessories designed for use with the stan-
dard “cigarette lighter” plug type to the 12V
power outlets (
page 325) in your vehicle
whenever possible.
iIf the engine is off, and the cigarette lighter
is being used extensively, the vehicle battery
may become discharged.

!If you use all power outlets in the vehicle,
make sure that the maximum current drawn
does not exceed 55 A.
iThe power outlets can be used to
accommodate 12V DC electrical accessories
(e.g. auxiliary lamps) up to a maximum of 240 W.
If the engine is off, the battery may become dis-
charged if used for long periods of time.
iYou can use the power outlets, except for
the power outlet in the front center console,
even if the ignition is switched off.
An emergency shut-off feature ensures that the
vehicle’s electrical voltage does not fall below a
minimum level. If the voltage drops to this mini-
mum level, the power outlets are automatically
switched off. This ensures that enough power re-
mains to start the engine.
iIf your vehicle is equipped with a smoking
package*, the storage compartment contains an
ashtray with cigarette lighter (
page 324) in-
stead.
