2016 MERCEDES-BENZ GLS SUV warning light

Important safety notes
G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
! Only operate the vehicle for a maximum of
ten seconds on a brake dynamometer. Switch off the ignition.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
! A function or performance test should only
be carried out on a twin-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
When ESP ®
is deactivated, the åESP®
OFF
warning lamp lights up continuously.
If the ÷ warning lamp and the åwarning
lamp are lit continuously, ESP ®
is not available
due to a malfunction.
Observe the information on warning lamps
(Y page 295) and display messages which may
be shown in the instrument cluster
(Y page 259).
i Only use wheels with the recommended tyre
sizes. Only then will ESP ®
function properly.
Characteristics of ESP ®General notes
If the ÷ ESP warning lamp goes out before
beginning the journey, ESP ®
is automatically
active.
If ESP ®
intervenes, the ÷ESP®
warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X When pulling away, only depress the acceler-
ator pedal as far as is necessary.
X Adapt your driving style to suit the prevailing
road and weather conditions. ECO start/stop function
The ECO start/stop function switches the
engine off automatically if the vehicle stops
moving. When pulling away again, the engine
starts automatically. ESP ®
remains in its previ-
ously selected status, e.g. if ESP ®
was deacti-
vated before the engine was automatically
switched off.
Deactivating/activating ESP ® Important safety notes
i Observe the "Important safety notes" sec-
tion (Y page 68).
You can select between the following ESP ®
sta-
tuses:
R ESP ®
is activated
R ESP ®
is deactivated G
WARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilises the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations descri-
bed in the following.
In the following situations, it may be better to
deactivate ESP ®
:
R when snow chains are used
R in deep snow
R on sand or gravel
Spinning the wheels results in a cutting action,
which enhances traction.
i Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not stabilise the vehicle if the vehi-
cle starts to skid or a wheel starts to spin. Driving safety systems

Off-road ESP ®
intervenes with a delay if there is
oversteering or understeering, thus improving
traction.
ESP ®
trailer stabilisation General notes
ESP ®
trailer stabilisation is not available in
Mercedes-AMG vehicles.
If your vehicle/trailer combination begins to
lurch, ESP ®
assists you in this situation. ESP ®
slows the vehicle down by braking and limiting
the engine output until the vehicle/trailer com- bination has stabilised.
Important safety notes G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent the vehicle/trailer combination from swerv-
ing. Trailers with a high centre 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.
If your vehicle/trailer combination begins to
lurch, you can only stabilise the vehicle/trailer
combination by depressing the brake firmly.
Trailer stabilisation is active above speeds of
about 60 km/h.
ESP ®
trailer stabilisation does not work if ESP ®
is deactivated or disabled because of a malfunc- tion. 74

radar sensors checked at a qualified specialist
workshop. This also applies to collisions at low
speeds where no damage to the front of the
vehicle is visible.
Following damage to the windscreen, have the
configuration and operation of the camera sys-
tem checked at a qualified specialist workshop.
Function X
To activate or deactivate: activate or deac-
tivate Active Brake Assist with cross-traffic
function using the on-board computer
(Y page 250).
If the Active Brake Assist with cross-traffic
function is deactivated, the æsymbol
appears in the multifunction display.
If you have activated DSR (Y page 227), the
Active Brake Assist with cross-traffic function is
deactivated.
This function issues a warning:
R at a speed of approximately 30 km/h or
higher, the distance maintained to the vehicle
travelling in front is insufficient for several
seconds.
The · distance warning lamp then lights
up in the instrument cluster.
R at a speed of approximately 7 km/h or more,
you rapidly approach a vehicle in front or a
pedestrian
An intermittent warning tone will then sound
and the ·distance warning lamp will light
up on the instrument cluster.
X Brake immediately to defuse the situation.
or
X Take evasive action provided it is safe to do
so.
Active Brake Assist with cross-traffic function
can also brake the vehicle automatically under
the following conditions:
R the driver and front passenger have their seat
belts fastened
and
R the vehicle speed is between approximately
7 km/h and 200 km/h Up to a speed of approximately 70 km/h, Active
Brake Assist with cross-traffic function may
react to:
R stationary objects in the path of your vehicle,
such as stopped or parked vehicles
R pedestrians in the path of your vehicle
i If an increased danger of collision exists,
preventative passenger protection measures
(PRE-SAFE ®
) are triggered (Y page 56).
If the risk of collision remains and you do not
brake, take evasive action or accelerate quickly,
the vehicle may perform automatic braking up to
the point of a full brake application. An auto-
matic full brake application is not performed
until immediately prior to an imminent accident.
If you apply the brake yourself in a critical sit-
uation or during autonomous braking, braking
assistance is provided according to the situa-
tion. If necessary, this increases the brake pres-
sure up to full brake application.
To avoid a collision, Active Brake Assist with
cross-traffic function calculates the brake force
necessary if:
R you approach an obstacle and
R Active Brake Assist with cross-traffic function
has detected a risk of a collision
When driving at a speed under30 km/h: if
you depress the brake pedal, Active Brake
Assist with cross-traffic function is activated.
Braking assistance from Active Brake Assist
with cross-traffic function is carried out at the
last possible moment.
When driving at a speed above30 km/h: if
you depress the brake pedal sharply, Active
Brake Assist with cross-traffic function auto-
matically increases the brake pressure to a
degree suited to the traffic situation.
Active Brake Assist with cross-traffic function
provides braking assistance in hazardous situa-
tions with vehicles in front within a speed range
between 7 km/h and 250 km/h. Driving safety systems

WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open. G
WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, especially when braking or abruptly changing directions.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
! The tailgate swings upwards and to the rear
when opened. Therefore, make sure that
there is sufficient clearance above and behind
the tailgate.
The opening dimensions of the tailgate can be
found in the "Vehicle data" section
(Y page 387).
Stow luggage or loads preferably in the luggage
compartment. Observe the loading guidelines
(Y page 312).

cally. The automatic obstacle detection with
reversing function is only an aid. It is not a sub-
stitute for your attention when opening and
closing the tailgate. G
WARNING
The reversing function does not react:
R to soft, light and thin objects, e.g. fingers
R over the last 8 mm of the closing path
