towing MERCEDES-BENZ GLC 2017 Owner's 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

lished between the Customer Assistance Center
and the vehicle occupants. R
If the vehicle occupants respond, the
Mercedes-Benz Customer Assistance Center
attempts to get more information on the
emergency. R
If there is no response from the vehicle occu-
pants, an ambulance is immediately sent to
the vehicle.
If no voice connection can be established to the
Mercedes-Benz Customer Assistance Center,
the system has been unable to initiate an emer-
gency call.
This can occur, for example, if the relevant
mobile phone network is not available. The indi-
cator lamp in the SOS button flashes continu-
ously.
The Call Failed message appears in the mul-
tifunction display and must be confirmed.
In this case, summon assistance by other
means.

! Do not use the trailer tow hitch for recovery
or towing. Do not use the towing eye for
recovery. this could damage the vehicle. If in
doubt, have the vehicle recovered using a
crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
! Shift the automatic transmission to position
\\ and do not open the driver's or front pas-
senger's door during towing. The automatic
transmission may otherwise shift to position
] , which could damage the transmission.

30 miles (50km). The towing speed of 30 mph
(50 km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the entire vehicle must be
raised and transported.
It is better to have the vehicle transported than
to have it towed away.
If the vehicle has suffered transmission damage,
have it transported on a transporter or trailer.
The automatic transmission must be in position
\\ when the vehicle is being towed. If the auto-
matic transmission cannot be shifted to position

same time cannot be detected by the tire pres-
sure loss warning system.
The tire pressure monitor is not able to warn you
of a sudden loss of pressure, e.g. if the tire is
penetrated by a foreign object. In the event of a
sudden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
movements.
The function of the tire pressure loss warning
system is limited or delayed if: R
snow chains are mounted on your vehicle's
tires. R
road conditions are wintry. R
you are driving on sand or gravel. R
you adopt a very sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration). R
you are towing a very heavy or large trailer. R
you are driving with a heavy load (in the vehi-
cle or on the roof).
Restarting the tire pressure loss warn-
ing system Restart the tire pressure loss warning system if
you have: R
changed the tire pressure R
changed the wheels or tires R
mounted new wheels or tires X
Before restarting, make sure that the tire
pressures are set properly on all four tires for
the respective operating conditions.
The recommended tire pressure can be found
on the Tire and Loading Information placard
on the B-pillar. Additionally, a tire pressure
table is attached to the fuel filler flap. The tire
pressure loss warning system can only give
reliable warnings if you have set the correct
tire pressure. If an incorrect tire pressure is
set, these incorrect values will be monitored. X
Also observe the notes in the section on tire
pressures ( Y
page 339).X
Make sure that the SmartKey is in position H
in the ignition lock ( Y

Note that the payload and the rear axle load
are reduced by the actual payload.
Towing a trailer is not possible with all models.
Further information ( Y

The drawbar load reduces the permissible over-

head on the trailer tow hitch.
The trailer drawbar noseweight is not included in
the towing weight.

The maximum permissible trailer drawbar nose-
weight is the maximum weight with which the
trailer drawbar can be loaded. The permissible
