2017 MERCEDES-BENZ GLC Owners Manual

You will find permissible trailer loads under
"Technical data" ( Y
page 371).
Loading a trailer R
When 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. R
The 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 R
Have 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. R
Check the gross axle weight rating of the front
and rear axles, the gross weight of the trailer
and trailer drawbar load. Towing a trailer 207

Tachometer
! Do not drive in the overrevving range, as this
could damage the engine.
The red band in the tachometer indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached.
Outside temperature display You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the temperature measured and
does not record the road temperature.
The outside temperature display is in the multi-
function display ( Y

Changes in the outside temperature are dis-
played after a short delay.

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.
