2017 MERCEDES-BENZ GLA SUV Owners Manual

Driving tips
R
Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine, and conse-
quently the vehicle's gradient-climbing capa-
bility from a standstill, decrease with increas- ing altitude.
If the trailer swings from side to side:
X Do not accelerate under any circumstances
X Do not countersteer
X Brake if necessary Folding out the ball coupling
Folding out the ball coupling G
WARNING
If the ball coupling is not correctly engaged,
the trailer can detach. There is a risk of an
accident.
Always engage the ball coupling as described. G
WARNING
If you release the ball coupling or it does not
engage correctly when folding in, it will swing out. Within pivoting range of the ball coupling,
there is an increased risk of an accident and
injury.
Only release the ball coupling if the pivoting
range is unobstructed. Always make sure that the ball coupling engages when folding in.

X Position the trailer on a level surface behind
the vehicle.
X Couple up the trailer.
X Establish the electrical connection between
the vehicle and the trailer.
X Check that the trailer lighting system is work-
ing.
A connected trailer is only detected when the
electrical connection is established correctly
and when the lighting system is working prop- erly. The function of other systems, such as
ESP ®
or PARKTRONIC also depends on this. Uncoupling a trailer
G
WARNING
If you uncouple a trailer with an engaged over- run brake, you could trap your hand between
the vehicle and the trailer drawbar. This poses a risk of injury.
Do not uncouple a trailer with an engaged
overrun brake.
! Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun brake.
! Remove the installed adapter cable before
folding in the ball coupling. Otherwise, dam-
age may occur to the rear bumper and the
adapter cable.
X Make sure that the transmission is in position
P.
X Apply the electric parking brake.
X Secure the trailer against rolling away.
X Remove the trailer cable and decouple the
trailer. Trailer power supply
! You can connect accessories to the perma-
nent power supply up to a maximum of 240 W. Towing a trailer
215Driving and parking Z

You cannot charge a trailer battery using the
power supply.
When it leaves the factory, your vehicle's trailer
socket is equipped with a permanent power
supply and a power supply that is switched on
via the ignition lock.
The permanent power supply is supplied via
trailer socket pin 9.
The power supply that is switched on via the
ignition lock is supplied via trailer socket pin 10.
The trailer's permanent power supply is
switched off in the event of low vehicle supply
voltage and after six hours at the latest.
You can find more information about fitting the
trailer electrics at a qualified specialist work-
shop.
X To switch the connected power supply on
or off: turn the key to position 2or 0respec-
tively (Y page 144). Failure check for LEDs
If LED lamps are fitted in the trailer, a malfunc-
tion message may appear in the multifunction
display even if there is no fault. The reason for
the error message may be that the current has
fallen below the minimum of 50 mA.
To ensure reliable operation of the failure indi-
cator, each LED chain in the trailer lighting must
be guaranteed a minimum current of 50 mA. Trailer with 7-pin connector
General notes Trailer with 7-pin connector:
you can connect
to the 13-pin socket on the ball coupling using
an adapter or, if necessary, an adapter cable.
Both can be obtained at a qualified specialist
workshop.
Fitting the adapter !
Make sure that there is sufficient cable play
so that the cable cannot become detached
when cornering.
! Remove the installed adapter cable before
folding in the ball coupling. Otherwise, dam-
age may occur to the rear bumper and the
adapter cable. X
Open the socket cover.
X Insert the plug connector with lug :into
groove =on the socket.

Important safety notes
G
WARNING
If you operate information and communica-
tion equipment integrated in the vehicle when driving, you could be distracted from the traf-
fic situation. This could also cause you to lose control of the vehicle. There is a risk of an
accident.
Only operate this equipment when the traffic
situation permits. If you cannot be sure of this,
stop the vehicle paying attention to road and
traffic conditions and operate the equipment
with the vehicle stationary.
You must observe the legal requirements for the
country in which you are currently driving when operating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer shows only display mes- sages or warnings from certain systems on the
multifunction display. You should therefore
make sure your vehicle is operating safely at alltimes.
If the operating safety of your vehicle is
impaired, park the vehicle safely as soon as pos-
sible. Contact a qualified specialist workshop.
For an overview, see the instrument cluster illus-
tration (Y page 34). Displays and operation
Instrument cluster lighting
The light sensor in the instrument cluster auto-
matically controls the brightness of the multi-
function display. In daylight, the displays in the
instrument cluster are not illuminated. The lighting in the instrument cluster, in the dis-
plays and the controls in the vehicle interior can
be adjusted using the brightness control knob.
The brightness control knob is located on the
bottom left of the instrument cluster
(Y page 34).
X Turn the brightness control knob clockwise or
anti-clockwise.
If the light switch is set to the Ã,Tor
L position, the brightness is dependent
upon the brightness of the ambient light. Speedometer with segments
The speedometer is divided into segments on
vehicles with Distance Pilot DISTRONIC.
The segments in the speedometer indicate
which speed range is available.
R Variable speed limiter is activated
(Y page 178):
The segments light up from the start of the
scale to the selected speed limitation.
R Distance Pilot DISTRONIC is activated
(Y page 180):
One or two segments in the stored speed
range light up.
R Distance Pilot DISTRONIC detects a vehicle in
front moving more slowly than the stored
speed:
The segments between the speed of the vehi- cle in front and the stored speed light up. Rev counter
! Do not drive in the overrevving range. Doing
so will damage the engine.
The red band in the rev counter indicates the
engine's overrevving range.
The engine is limited within a range 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 measured air temperature
and not the road surface temperature. Displays and operation
217On-board computer and displays Z

The outside temperature display is in the multi-
function display (Y page 220).
There is a short delay before a change in outside
temperature appears in the multifunction dis-
play. Coolant temperature display

WARNING
If you open the bonnet while the engine is
overheating or while there is a fire in the
engine compartment, you could come into
contact with hot gases or other leaking ser-
vice products. There is a danger of injury. Allow an overheating engine to cool down
before opening the bonnet. If there is a fire in the engine compartment, leave the bonnet
closed and notify the fire brigade.
The coolant temperature gauge is in the instru-
ment cluster on the right-hand side (Y page 34).
Under normal operating conditions and with the correct coolant level, the coolant temperature
may rise to 120 †.
At high outside temperatures and when driving
in mountainous terrain, the coolant temperature may rise to the end of the scale. Operating the on-board computer
