Only release the ball coupling if the pivoting
range is unobstructed. Always make sure that the ball coupling engages when folding in.
When reversing the towing vehicle, make sure
there is nobody between the trailer and the vehi- cle.
Couple and uncouple the trailer carefully. If youdo not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning circle
This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain a safe distance. Drive carefully.
When towing a trailer, always adjust your speed to the current road and weather conditions. Do
not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on towing a trailer
General notes Trailer towing is not possible on the following
models:
R Mercedes‑AMG GLA 45 4MATIC
Items of optional equipment may influence the
effective trailer loads for the vehicle. Please find the applicable trailer loads for your vehicle on
the registration certificate.
When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for a maxi-
mum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 337).
Please note that when towing a trailer, the fol-
lowing driving systems have limited availability
or are not available at all:
R Parking Assist PARKTRONIC (Y page 193)
R Blind Spot Assist (Y page 209) The height of the ball coupling changes with the
load of the vehicle. If necessary, use a trailer
with a height-adjustable drawbar.
You will find fitting dimensions and loads under"Technical data" (Y page 359).
Driving tips Observe the information on ESP
®
trailer stabili-
sation (Y page 75).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the legally prescri-
bed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissible rear axle load is increased
when towing a trailer. See the "Technical data"
section to find out whether this applies to your
vehicle. If when towing, the rear axle load is
increased even partly, the vehicle/trailer com-
bination may not exceed a maximum speed of
100 km/h for reasons concerning the operating
permit. This also applies in countries in which
the permissible maximum speed for vehicle/
trailer combinations is above 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer and the vehicle will consume
more fuel.
Shift to a lower gear in good time on long and
steep downhill gradients. For vehicles with auto-
matic transmission, you need to have selected
manual drive program M(Y page 161).
This also applies if you have activated cruise
control, the speed limiter or Distance Pilot
DISTRONIC.
This will use the braking effect of the engine, so less braking will be required to maintain the
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive pro-
gram Mis temporarily activated (vehicles with
automatic transmission): the automatic trans-
mission may switch back to the last active auto-
matic drive program Eor S. The automatic trans-
mission may shift to a higher gear. This can
reduce the engine's braking effect. Towing a trailer

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
