sensor MERCEDES-BENZ METRIS 2017 MY17 Operator’s Manual

Depending on the equipment in the vehicle, you
can activate or deactivate ESP®when the
engine is running by using the åbutton or by
using the on-board computer:
Ron vehicles without steering wheel buttons
(Ypage 174)
Ron vehicles with steering wheel buttons
(Ypage 184)
å button (equipment-dependent)
XTo activate/deactivate: when the engine is
running, press the åbutton.

cluster lights up when ESP
®is deactivated.
Trailer stabilization
Observe the important safety guidelines for the
driving safety system (Ypage 64).
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with a high center of gravity can
tip over before ESP
®can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
ESP
®trailer stabilization counteracts critical
driving situations in good time and thereby pro- vides 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 stabi-
lization 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 to
stabilize the vehicle/trailer combination in this
s
ituation.
ESP
®trailer stabilization is activated above
speeds of about 40 mph (65 km/h).
If ESP
®is switched off or deactivated because of
a malfunction, the trailer stabilization system
will not function.
Crosswind Assist
Observe the important safety guidelines for the
driving safety system (Ypage 64).
Strong crosswind gusts can impair the road-
holding of your vehicle when driving straight
ahead. The Crosswind Assist function integra-
ted in ESP
®reduces these impairments.
Depending on the direction and intensity of the
side wind, Crosswind Assist intervenes auto-
matically. ESP
®intervenes with stabilizing brak-
ing to assist you in keeping the vehicle in the
lane. When Crosswind Assist intervenes, the
display shows the traffic sign for strong side
winds and the Crosswind Assist
message.
Crosswind Assist is activated automatically
above a vehicle speed of approx. 50 mph
(80 km/h) when the vehicle is driving straight
ahead or cornering gently.
Crosswind Assist does not react:
Rin the event of severe jolts and vibrations, e.g.
when driving over uneven surfaces or pot-
holes
Rwhen grip is reduced, e.g. on snow or ice or
when hydroplaning
Crosswind Assist does not work if ESP
®is deac-
tivated or disabled because of a malfunction.

!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield can scratch the glass
if wiping takes place when the windshield is
dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
!If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield wipers may be activated inadvertently.
This could then damage the windshield wiper
blades or scratch the windshield.
For this reason, you should always switch off
the windshield wipers in dry weather.

Breaking-in notes
Important safety notes
In certain driving and driving safety systems, the
sensors adjust automatically while a certain dis-
tance is being driven after the vehicle has been
delivered or after repairs. Full system effective- ness is not reached until the end of this teach-in
procedure.
New or replaced brake pads and brake discs
only reach their optimal braking effect after a
few hundred kilometers of driving. Until then,
compensate for this by applying greater force to
the brake pedal.
The first 1000 miles (1500 km)
For the service life and economy of your vehicle
it is crucial that you break in the engine with due
care.
RTherefore, protect the engine for the first
1000 miles (1500 km) by driving at varying
vehicle and engine speeds.
RAvoid overstraining the vehicle and high
engine speeds during this period, e.g. driving
at full throttle. Do not exceed Øof the per-
missible maximum speed for each gear.
RDo not change down a gear manually in order to brake.
RTry to avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate the
vehicle to full speed.
iYou should also observe these notes on
breaking-in if the engine or parts of the drive
train on your vehicle have been replaced.
Driving
Important safety notes
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!Warm up the engine quickly. Do not use the
engine's full performance until it has reached
operating temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
120Driving
Driving and parking

!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately. Drive
on for a short while. The brakes are cooled down
more quickly in the airflow.
Wet road surfaces
If you have been driving for a long time in heavy
rain without braking, there may be a delayed
response when you first apply the brakes. This
may also occur after driving through a car wash
or deep water.
You must depress the brake pedal more firmly.
Maintain a longer distance to the vehicle in
front.
While paying attention to the traffic conditions,
you should brake the vehicle firmly after driving
on a wet road surface or through a car wash. This
heats the brake discs, so that they dry more
quickly, which protects them against corrosion.
Limited braking performance on salt-
treated roads
When driving on salted roads, salt may start to
build up on the brake disks and brake pads. This can increase braking distances considerably.
Maintain a greater distance to the vehicle in
front.
To remove any build-up of salt that may have
formed:
XApply the brakes at the start of the journey,
occasionally during journey and at the end of
the journey. Make sure that you do not endan-
ger other road users when doing so.
Checking the brake pad thickness
In addition to monitoring using the brake pad
wear sensor, regularly monitor and check all of
the brake pads by performing a visual inspection
to look for pad material wear.
If you are unable to check the brake wear on the
inside of the wheels, remove the wheels with the tools provided.
Make sure that the brake pad material thickness
never falls below 0.12 in (3 mm). Have the brake pads checked and replaced at a qualified spe-
cialist workshop, if necessary. Do not solely rely on the brake pad wear sensor.
It is strongly recommended that you have the
brake pads checked at a qualified specialist
workshop at every service displayed in the main-
tenance interval indicator, prior to long journeys
and whenever the wheels are removed.
New brake discs and brake pads/
linings
New brake pads and brake discs only reach their
optimal braking effect after about 60 miles
(100 kilometers). Until then, compensate for
this by applying greater force to the brake pedal.
For safety reasons, Mercedes-Benz recom-
mends only installing the following brake discs
and brake pads/linings:
Rbrake discs that have been approved by
Mercedes-Benz
Rbrake pads/linings that have been approved
by Mercedes-Benz or are of an equivalent
standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake discs or brake pads/
linings on an axle at the same time and only have
them replaced at a qualified specialist work-
shop. When replacing the brake discs, always
have the brake pads/linings replaced at the
same time.
Parking brake
GWARNING
If you must brake the vehicle with the parking brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the vehi-
cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
When driving on wet roads or dirt-covered sur-
faces, road salt and/or dirt may get into the
parking brake. This causes corrosion and a
reduction of braking force.
In order to prevent this, drive with the parking
brake lightly applied from time to time. When
doing so, drive for a distance of approximately

into account road, weather or traffic conditions.
The distance warning function is only an aid. You
are responsible for the distance to the vehicle in
front, for vehicle speed, braking in good time
and for staying in your lane.
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at slow
speeds where there is no visible damage to the
front of the vehicle.
If you change wheel size, make sure they corre- spond to the correct wheel size category
(
Ypage 277). If the category is changed without
recoding the control units in the vehicle, the
functioning of the distance warning feature may
be impaired. COLLISION PREVENTION ASSIST
may then detect a malfunction and switch itself
off.
Operation
XTo activate/deactivate: activate or deacti-
vate the distance warning function in the on-
board computer (
Ypage 185).
If the distance warning function of COLLISION
PREVENTION ASSIST is activated, the display
shows the Äsymbol:
Rin the header
Rin the Status Overviewof the Assist.menu (Ypage 184)
At speeds up to approx 20 mph (30 km/h) the
display in vehicles with Active Parking Assist
first shows the ístatus indicator. Only up to
a speed of about 20 mph (30 km/h) does the display show the Äsymbol instead of the
í status indicator.
The distance warning function can help you to
minimize the risk of a front-end collision with a
vehicle ahead or reduce the effects of such a
collision. With the help of the radar sensor sys-
tem, the distance warning function can detect
obstacles that are in the path of your vehicle for
an extended period of time. If the distance warn-
ing function detects that there is a risk of a col-
lision, you will be warned visually and, where
necessary, acoustically. Without your interven-
tion, the distance warning function cannot pre-
vent a collision.
The distance warning function issues a warning
at speeds:
Rfrom about 4 mph (7 km/h) if you approach a
vehicle traveling in front or a stationary vehi-
cle too quickly. The ·warning lamp in the instrument cluster then lights up and an inter-
mittent warning tone also sounds.
At speeds up to about 45 mph (70 km/h), the
system also detects stationary obstacles, for
example stopped or parked vehicles.
XBrake immediately until the distance from the
obstacle increases and the risk of a front-end
collision passes.
or
XTake evasive action, provided it is safe to do
so.
Adaptive Brake Assist
General notes
Adaptive Brake Assist evaluates the traffic sit-
uation with the help of the radar sensor system and can detect obstacles which have been in
your vehicle's path for an extended period of
time. From speeds above 4 mph (7 km/h), Adap-
tive Brake Assist aids you in braking during haz-
ardous situations.
Up to a speed of approximately 125 mph
(200 km/h), Adaptive Brake Assist is capable of
reacting to moving obstacles that have already
been detected as such at least once over the
period of observation.
Important safety notes
GWARNING
Adaptive Brake Assist does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rto stationary obstacles
Rwhen cornering
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
Driving systems145
Driving and parking
Z

In such cases, Adaptive Brake Assist can:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
In particular, the detection of obstacles can be
impaired in the case of:
Rdirt on the sensors or anything else covering
the sensors
Rsnow or heavy rain
Rinterference from other radar sources
Rstrong radar reflections, for example, in park-
ing garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause Adaptive Brake Assist to inter-
vene.
If you fail to adapt your driving style, Adaptive
Brake Assist can neither reduce the risk of acci-
dent nor override the laws of physics. Adaptive
Brake Assist cannot take into account road,
weather or traffic conditions. Adaptive Brake
Assist is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed, braking in good time and for staying in
your lane.
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at slow
speeds where there is no visible damage to the
front of the vehicle.
If you change wheel size, make sure they corre- spond to the correct wheel size category
(
Ypage 277). If the category is changed without
recoding the control units in the vehicle, the
functioning of Adaptive Brake Assist may be
impaired. COLLISION PREVENTION ASSIST may
then detect a malfunction and switch itself off.
If Adaptive Brake Assist is not available due to a
malfunction in the radar sensor system, the
brake system remains available with full brake
boosting effect and BAS.
Operation
With the help of the radar sensor system, Adap-
tive Brake Assist can detect obstacles that have been in the path of your vehicle for an extended
period of time. Ada

ptive Brake Assist does not
react to stationary obstacles. If Adaptive Brake
Assist detects a risk of collision with a vehicle
traveling in front or with a stationary obstacle,
the system calculates the braking force neces-
sary to avoid this collision. If you apply the
brakes forcefully, Adaptive Brake Assist will
automatically increase the braking force to a
level suitable for the traffic conditions.
XBrake until the distance to the obstacle
increases and the risk of a collision passes.
ABS prevents the wheels from locking.
The brakes function as usual again if:
Ryou release the brake pedal
Rthere is no longer any danger of a collision
Rno obstacle is detected in front of your vehicle
Braking assistance is then ended.
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sensors
in the bumper. It supports you from speeds of
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your atten-
tion to vehicles detected in the monitored area.
If you then switch on the corresponding turn
signal to change lane, you will also receive an
optical and audible collision warning.
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
146Driving systems
Driving and parking

Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
In particular, the detection of obstacles can be
impaired in the case of:
Rdirt on the sensors or anything else covering
the sensors
Rfog, heavy rain or snow
Rnarrow vehicles, e.g. motorcycles or bicycles
Rvery wide lanes
Rnarrow lanes
Rvehicles not driving in the middle of their lane
Rbarriers or other road boundaries
Vehicles in the monitoring range are then not
indicated.
iUSA only:
This device has been approved by the FCC as
a "Vehicular Radar System". The radar sensor
is intended for use in an automotive radar
system only. Removal, tampering, or altering
of the device will void any warranties, and is
not permitted by the FCC. Do not tamper with,
alter, or use in any non-approved way.
Any unauthorized modification to this device
could void the user’s authority to operate the
equipment.
Monitoring range of the sensors
Blind Spot Assist monitors the area shown in the
diagram up to 118 in (3 m) behind and directly
next to your vehicle.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side
of their lane.
Due to the nature of the system:
Rwarnings may be issued in error when driving
close to crash barriers or similar solid lane
borders.
Rwarnings may be interrupted when driving
alongside long vehicles, for example trucks,
for a prolonged time
The two sensors for Blind Spot Assist are inte-
grated into the sides of the rear bumper. Make
sure that the bumper is free of dirt, ice or slush
in the vicinity of the sensors. The radar sensors
must not be covered, for example by rear-moun-
ted cycle racks or overhanging loads. Following
a severe impact or in the event of damage to the
bumper, have the function of the radar sensors
checked at a qualified specialist workshop.
Blind Spot Assist may otherwise not work prop-
erly.
