2020 MERCEDES-BENZ METRIS warning lights

ESP
®
is deactivated if the å warning lamp
in the instrument cluster is lit when the engine
is running.
Only use wheels with the recommended tire
sizes. Only then will ESP ®
function properly.
Deactivating or activating ESP ®G
WARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations
described in the following.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel
Activate ESP ®
as soon as the situations descri-
bed above no longer apply. Otherwise, ESP ®
assistance for stabilizing the vehicle will
remain significantly reduced, even if the vehi-
cle starts to skid.
If you deactivate ESP ®
:
R the å warning lamp in the instrument
cluster lights up
R the ÷ warning lamp in the instrument
cluster flashes if the wheels are spinning
R ESP ®
assistance for stabilizing the vehicle in
the lower speed range up to approximately
37 mph (60 km/h
) is significantly reduced
R engine torque is no longer limited and the
drive wheels are able to spin. The spinning
of the wheels results in a cutting action for
better traction on loose surfaces
R traction control is still activated
R ESP ®
still provides support when you brake
Depending on the equipment in the vehicle,
you can activate or deactivate ESP ®
when the
engine is running by using the å button or
by using the on-board computer:
R on vehicles without steering wheel buttons
(Y page 179)
R on vehicles with steering wheel buttons
(Y page 190) å button (equipment-dependent)
X To activate/deactivate: when the engine
is running, press the å button.
The å warning lamp in the instrument
cluster lights up when ESP ®
is deactivated.
Trailer stabilization Observe the important safety guidelines for
the driving safety system (
Y page

66). G
WARNING
If road and weather conditions are poor,
trailer stabilization will not be able to pre-
vent the vehicle/trailer combination from
swerving. Trailers with a high center of grav-
ity can tip over before ESP ®
can detect this.
There is a risk of an accident.
Always adapt your driving style to the pre-
vailing road and weather conditions.
ESP ®
trailer stabilization counteracts critical
driving situations in good time and thereby
provides considerable assistance when driving
with a trailer. Trailer stabilization is part of
ESP ®
.
If the sensor system and evaluation logic
detect trailer swinging movements, ESP ®
trailer stabilization firstly brakes individual
vehicle wheels in a targeted manner. It thus
counteracts swinging movements. If the
swinging movements do not stop, the vehicle
is braked until the vehicle/trailer combination
is stabilized. If necessary, the vehicle's engine
output is limited.
If your vehicle with trailer (vehicle/trailer com-
bination) starts to swerve, you will be able to
stabilize the vehicle/trailer combination only
by braking. ESP ®
trailer stabilization helps you Driving safety systems

cipitation. They can only be operated together
with the parking lamps or with the low-beam
headlamps.

WARNING
If you open the rear-end doors 90°, the rear
lighting systems are no longer visible. The
vehicle will then be difficult for other road
users to see or will not be seen by them at
all, particularly if it is dark or visibility is
poor. There is a risk of an accident.
You should therefore ensure in this and simi-
lar situations that the vehicle is visible from
the rear in accordance with the relevant
national regulations, by using the warning
triangle, for instance. Exterior lighting

Important safety notes

WARNING
Bulbs, lamps and connectors can get very
hot when operating. If you change a bulb,
you could burn yourself on these compo-
nents. There is a risk of injury.
Allow these components to cool down
before changing a bulb. !
Make sure the bulbs are always securely
installed.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore
make sure that these function correctly at all
times. Have the headlamp setting checked
regularly.
Observe the following notes when changing a
bulb:
R Always switch off the ignition before replac-
ing bulbs in the lighting system. This will
prevent a short circuit.
R Wear gloves and eye protection when
changing a bulb.
R Do not use a bulb that has been dropped or
that has scratches on its glass tube. The
bulb could may explode.
R A bulb could explode if:
- you touch it
- it is hot
- you drop it
- you scratch or score it
R Marks on the glass tube shorten the operat-
ing life of a bulb. Do not touch the glass
tube with your bare hands. If necessary,
clean the glass tube when cold with alcohol
or spirit. Then rub off the glass tube with a
clean, lint-free cloth.
R Make sure that bulbs are protected from
moisture when operating and that they do
not come into contact with liquids. Make
sure that seals are seated correctly and
replace damaged seals.
R Check the contacts for signs of corrosion
and clean these if required.
R Only operate bulbs in closed lamps which
have been designed for this purpose.
R Only use spare bulbs of the same type, with
the prescribed voltage and the correct wat-
tage.
R If the new bulb does not light up, consult a
qualified specialist workshop. Replacing bulbs
