2017 MERCEDES-BENZ GLC SUV air condition

For safety reasons, Mercedes-Benz recom-
mends only installing the following brake disks
and brake pads/linings:
Rbrake disks that have been approved by
Mercedes-Benz
Rbrake pads/linings that have been approved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake disks or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake disks and brake pads/
linings on an axle at the same time. Always
install new brake pads/linings when replacing
brake disks.
The vehicle is equipped with lightweight brake
disks to which the wheel assembly with rim and
threaded connection is matched.
The use of brake disks other than those
approved by Mercedes-Benz can change the
track width and is subject to approval, if appli-
cable.
Shock-type loads when handling the brake
discs, such as when changing wheels, can lead
to a reduction in comfort when driving with light-
weight brake discs. Avoid shock-type loads on
the lightweight brake disks, particularly on the
brake plate.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for
your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard. Brake
fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth on
the road surface, there is a danger of hydro-
planing occurring, even if:
Ryou drive at low speeds
Rthe tires have adequate tread depth
For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
Rlower your speed
Ravoid ruts
Ravoid sudden steering movements
Rbrake carefully
Driving on flooded roads
!Bear in mind that vehicles traveling in front
or in the opposite direction create waves. This
may cause the maximum permissible water
depth to be exceeded.
Failure to observe these notes may result in
damage to the engine, electrical systems and
transmission.
If you have to drive on stretches of road on which
water has collected, please bear in mind that:
Rin the case of standing water, the water level may be no higher than the lower edge of the
vehicle body
Ryou should drive no faster than walking pace
Winter driving
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steering and

In such cases, apply the brakes yourself and
try to take evasive action.
!When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat-
ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
Rwhen towing the vehicle
Rin the car wash
DISTRONIC PLUS can neither reduce the risk of
an accident if you fail to adapt your driving style
nor override the laws of physics. DISTRONIC
PLUS cannot take account of road, weather and traffic conditions. DISTRONIC PLUS is only an
aid. You are responsible for maintaining a safe
distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
Do not use DISTRONIC PLUS:
Rin road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rin poor visibility, e.g. due to fog, heavy rain or
snow
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line.
In particular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for exam-
ple in parking garages
If DISTRONIC PLUS no longer detects a vehicle
in front, DISTRONIC PLUS may unexpectedly
accelerate the vehicle to the stored speed. This speed may:
Rbe too high if you are driving in a filter lane or
an exit lane
Rbe so high in the right lane that you pass vehi-cles driving on the left (left-hand drive coun-
tries)
Rbe so high in the left lane that you pass vehi-
cles driving on the right (in countries where
they drive on the left)
If there is a change of drivers, advise the new
driver of the speed stored.

DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot helps you keep the vehicle in the
center of the lane by means of moderate steer-
ing interventions in a speed range from
0–125 mph (0–200 km/h).
It monitors the area in front of your vehicle by
means of multifunction camera:, at the top of
the windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),
Stop&Go Pilot focuses on the vehicle in front,
taking into account lane markings, e.g. when
you are following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h),
Steering Assist focuses on clear lane markings
(left and right), only focusing on the vehicle in
front if clear lane markings are not present.
If these conditions are not present, Steering
Assist and Stop&Go Pilot cannot provide assis-
tance.
DISTRONIC PLUS must be active in order for the
function to be available.
Important safety notes
If you fail to adapt your driving style, DISTRONIC
PLUS with Steering Assist and Stop&Go Pilot
can neither reduce the risk of an accident nor
override the laws of physics. It cannot take
account of road, weather and traffic conditions.
DISTRONIC PLUS with Steering Assist and

ou are responsible
for maintaining a safe distance to the vehicle in front, for vehicle speed, for braking in good time
and for staying in lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions and does not detect all road users. If
you are following a vehicle which is driving
towards the edge of the road, your vehicle could
come into contact with the curb or other road
boundaries. Be particularly aware of other road
users, e.g. cyclists, that are directly next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can be
corrected at any time if you steer slightly in theopposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, steering inter-
vention is not sufficient to bring the vehicle back
to the lane. In such cases, you must steer the vehicle yourself to ensure that it does not leave
the lane.
The system may be impaired or may not function
if:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
Rthere are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
Rthere are highly variable shade conditions on the roadway
The system is switched to passive and no longer
assists you by performing steering interventions
if:
Ryou actively change lane
Ryou switch on the turn signal
Ryou take your hands off the steering wheel or do not steer for a prolonged period of time
Steering Assist and Stop&Go Pilot are activated
again automatically after a lane chang
e is com-
pleted.
Steering Assist and Stop&Go Pilot do not pro-
vide any support:
Ron very sharp corners
Rwhen a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the important safety notes
for DISTRONIC PLUS (
Ypage 164).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with

AIR BODY CONTROL
General notes
AIR BODY CONTROL is an air suspension system
with variable damping for improved driving com- fort. All-round level control ensures the best
possible suspension and constant ground clear-
ance, even with a laden vehicle. When you drive
fast, the vehicle is lowered automatically to
improve driving safety and to reduce fuel con-
sumption. There is also the option to manually
adjust the vehicle level. AIR BODY CONTROL
consists of level setting, level control and the
ADS Adaptive Damping System.
The vehicle level can be set using the DYNAMIC SELECT switch (
Ypage 139) or the level button
(Ypage 173). The setting always corresponds
to the last selected function.

AMG sports suspension based on AIR
BODY CONTROL (Mercedes-AMG vehi-
cles)
General notes
The electronically controlled damping system
works continuously. This improves driving
safety and ride comfort.
The damping is tuned individually to each wheel
and depends on:
Ryour driving style, e.g. sporty
Rthe road surface condition, e.g. bumps
Ryour individual selection of Sport, Sport+ or
Comfort
The suspension setting is adjusted using the
corresponding button in the center console.
iThe mode can also be set using the
DYNAMIC SELECT switch (Ypage 139).
This is possible only if the same mode is
selected for the suspension by pressing the
button on the center console for AMG sports
suspension based on AIR BODY CONTROL
and the DYNAMIC SELECT switch. This is the
case, for example, when both are set to Com- fort mode.
Each time you start the engine with the Smart-
Key or the Start/Stop button, Comfort mode is
activated. For further information about starting
the engine, see (
