General notes X
Turn the SmartKey to position 1 in the ignition
lock ( Y
page 145).
The sockets can be used for accessories with a
maximum draw of 180 W (15 A). Accessories
include such items as chargers for mobile
phones.
If you use the sockets for long periods when the
engine is switched off, the battery may dis-
charge.
An emergency cut-out ensures that the on-
board voltage does not drop too low. If the on-
board voltage is too low, the power to the sock-
ets is automatically cut. This ensures that there
is sufficient power to start the engine. Socket in the front center console X
To open: briefly press marking

! Note that work and repairs on the 115 V
power socket should only be carried out by
qualified specialist personnel.
General notes The 115 V power socket provides an alternating
voltage of 115 V so that small electronic devices
can be connected. These devices, such as
games consoles, chargers and laptops, must not
consume more than a maximum of 150 watts
altogether.
Requirements for operation of these devices: R
the electronic device that you connect has a
suitable connector and conforms to stand-
ards specific to the country you are in. R
the plug of the electronic device is plugged
correctly into 115 V power socket. R
the maximum wattage of the device to be
connected must not exceed 150 watts. R
the on-board power supply is within a permis-
sible voltage range. R
the 12 V sockets in the center console in the
front compartment ( Y
page 296) and in the
trunk are functional ( Y
page 297).
Using the 115 V power socket The 115 V socket is in the center console in the
rear compartment on vehicles with a rear bench
seat or electrically adjustable rear seats. X

You can find the valid maximum permissible
gross vehicle weight rating for your vehicle on
the Tire and Loading Information placard.
Number of seats
Maximum number of seats C indicates the
maximum number of occupants allowed to
travel in the vehicle. This information can be
found on the Tire and Loading Information plac-
ard.
i The specifications shown on the Tire and
Loading Information placard in the illustration
are examples. The number of seats is vehicle-
specific and can differ from the details shown.
The number of seats in your vehicle can be
found on the Tire and Loading Information
placard. Determining the correct load limit
Step-by-step instructions The following steps have been developed as
required of all manufacturers under Title 49,
Code of U.S. Federal Regulations, Part 575 pur-
suant to the "National Traffic and Motor Vehicle
Safety Act of 1966". X
Step 1: Locate the statement "The combined
weight of occupants and cargo should never
exceed XXX kg or XXX lbs." on your vehicle's
Tire and Loading Information placard. X
Step 2: Determine the combined weight of
the driver and passengers that will be riding in
your vehicle. X
Step 3: Subtract the combined weight of the
driver and passengers from XXX kilograms or
XXX lbs. X
Step 4: The resulting figure equals the avail-
able amount of cargo and luggage load capa-
city. For example, if the "XXX" amount equals
1400 lbs and there will be five 150-lb pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
650 lbs (1400 - 750 (5 x 150) = 650 lbs). X
Step 5: Determine the combined weight of
luggage and cargo being loaded on the vehi-
cle. That weight may not safely exceed the
available cargo and luggage load capacity cal-
culated in step 4.
Example: steps 1 to 3 The following table shows examples on how to calculate total and cargo load capacities with varying
seating configurations and number and size of occupants. The following examples use a load limit of
1500 lbs (680 kg). This is for illustration purposes only. Make sure you are using the actual load
limit for your vehicle stated on your vehicle's Tire and Loading Information placard ( Y
page 353).
The greater the combined weight of the occupants, the lower the maximum luggage load.
Example 1
Step 1 R
Combined maximum weight of occupants and load (data from the Tire and Loading Information
placard): 1500 lbs (680 kg)
Step 2 R
Number of people in the vehicle (driver and occupants): 5 R
