ESP MERCEDES-BENZ GLC 2017 Repair 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

Soon Canada only:
The tire pressure loss warning system has detected a significant loss
in pressure.
A warning tone also sounds.
Possible causes: R
you have changed the positions of the wheels and tires or installed
new wheels and tires R
the tire pressure in one or more tires has dropped significantly
G WARNING
Tire pressures that are too low pose the following hazards: R
they may burst, especially as the load and vehicle speed increase. R
they may wear excessively and/or unevenly, which may greatly
impair tire traction. R
the driving characteristics, as well as steering and braking, may be
greatly impaired.
There is a risk of an accident. X
Stop the vehicle without making any sudden steering or braking
maneuvers. Pay attention to the traffic conditions as you do so. X
Secure the vehicle against rolling away ( Y
page 154).X
Check the tires and, if necessary, follow the instructions for a flat
tire ( Y
page 321). X
Check the tire pressures and, if necessary, correct the tire pressure. X
Restart the tire pressure loss warning system when the tire pres-
sure is correct ( Y

Check Tire Pressure
Then Restart Run
Flat Indicator Canada only:
The tire pressure loss warning system generated a display message
and has not been restarted since. X
Set the correct tire pressure in all four tires. X
Restart the tire pressure loss warning system ( Y

Please Correct Tire
Pressure The tire pressure is too low in at least one of the tires, or the tire
pressure difference between the wheels is too great. X
Check the tire pressures at the next opportunity ( Y

Warning/
indicator
lamp Q Signal type
Possible causes/consequences and P Solutions
%
Q The yellow ABS warning lamp is lit while the engine is running.
ABS (anti-lock braking system) is malfunctioning.
If there is an additional warning tone, the EBD (electronic brake force distribution)
is malfunctioning.
Other driving systems and driving safety systems may also malfunction.
G WARNING
The brake system continues to function normally, but without the functions listed
above. The front and rear wheels could therefore lock if you brake hard, for exam-
ple.
The steerability and braking characteristics may be severely affected. The braking
distance in an emergency braking situation can increase.
If ESP ®
is not operational, ESP ®
is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident. X
Observe the additional display messages in the multifunction display. X
Drive on carefully. X
Visit a qualified specialist workshop immediately.
If the ABS control unit is faulty, there is also a possibility that other systems, such
as the navigation system or the automatic transmission, will not be available.
