MERCEDES-BENZ G-CLASS 2018 Owner's Manual

Permissible trailer and drawbar loads
Weight specifications
The gross trailer weight is calculated as the
weight of the trailer plus the weight of the load
and the trailer's equipment.
You will find permissible trailer loads under
"Technical data" (
Ypage 291).
Loading a trailer
RWhen loading the trailer, make sure that nei-
ther the permissible gross trailer weight nor
the permissible gross vehicle weight are
exceeded. The permissible gross vehicle
weight is indicated on the identification plate on the B-pillar on the driver's side of the vehi-
cle.
You can find the maximum permissible values
on the type plates of your vehicle and the
trailer. When calculating how much weight
the vehicle and trailer may carry, pay atten-
tion to the respective lowest values.
RThe trailer drawbar load on the ball coupling
must be added to the rear axle load to avoid
exceeding the permissible gross axle weight.
The permissible gross vehicle weight is indi-
cated on the identification plate on the B-pil-
lar on the driver's side of the vehicle.
Mercedes-Benz recommends a trailer load
where the trailer drawbar noseweight accounts
for 8% to 15% of the permissible gross trailer
weight.
Additional accessories, passengers and load
reduce the permissible trailer load and nose-
weight that your vehicle can tow.
Checking the vehicle and trailer weight
RHave the towing vehicle, including the driver,
passengers and load, and completely loaded
trailer weighed on a suitable weighing
machine. This will allow you to ensure that the
weights of the towing vehicle and trailer com-
ply with the maximum permissible values.
RCheck the gross axle weight rating of the front
and rear axles, the gross weight of the trailer
and trailer drawbar load.
Trailer power supply
!
You can connect accessories with a maxi-
mum power consumption of 180 W to the
permanent power supply.
You must not charge a trailer battery using the
power supply.
The trailer socket of your vehicle is equipped at
the factory with a permanent power supply.
The permanent power supply is supplied via
trailer socket pin 9.
A qualified specialist workshop can provide
more information about installing the trailer
electrics.
Trailer with 7-pin connector
General notes
Trailers with 7-pin connector: you can make a
connection to the 13-pin connector on the ball
coupling using an adapter plug or, if necessary,
an adapter cable. Both can be obtained in a
qualified specialist workshop.
Installing the adapter
!Make sure that there is enough slack in the
cable for cornering so that the cable cannot
become detached.
XOpen the socket cover.
XInsert the connector with lug :into
groove ;on the socket and turn it clockwise
to the stop.
XMake the cover engage.
XIf you are using an adapter cable, secure the
cable to the trailer with cable ties.
When the socket is connected, PARKTRONIC is
deactivated.

Coolant temperature gauge
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
!If the coolant temperature is too high, a dis-
play message is shown.
If the coolant temperature display is in the
area marked in red, do not continue driving.
Otherwise, the engine will be damaged.
The coolant temperature gage is in the instru-
ment cluster on the right-hand side (
Ypage 32).
Under normal operating conditions and at the
correct coolant level, the gauge may rise to the
H marking.
