2015 MERCEDES-BENZ GLE SUV warning lights

G
WARNING
The distance warning function does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation; do not rely on the distance warning
function alone.
Function The distance warning function issues a warning at speeds:
R of approximately 30 km/h or more, if, over
several seconds, the distance maintained to
the vehicle travelling in front is insufficient.
The · distance warning lamp then lights
up in the instrument cluster.
R of approximately 7 km/h or more, if you rap-
idly approach a vehicle in front. An intermit-
tent warning tone will then sound and the
· distance warning lamp will light up in the
instrument cluster.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause the system to display a warning. With the help of the radar sensor system, the
distance warning function can detect obstacles
that are in the path of your vehicle for an exten-
ded period of time.
Up to a speed of approximately 70 km/h, the
distance warning function can also react to sta-
tionary obstacles, such as stopped or parked
vehicles.
Autonomous braking function If the driver does not react to the distance warn-
ing signal in a critical situation, COLLISION PRE- VENTION ASSIST PLUS can assist with the
autonomous braking function.
The autonomous braking function:
R gives the driver more time to react to critical
driving situations
R can help the driver to avoid an accident or
R reduces the effects of an accident
Vehicles without DISTRONIC PLUS: the
autonomous braking function is available in the
following speed ranges:
R 7 - 105 km/h for moving objects
R 7 - 50 km/h for stationary objects
Vehicles with DISTRONIC PLUS: the autono-
mous braking function is available in the follow-
ing speed ranges:
R 7 - 200 km/h for moving objects
R 7 - 50 km/h for stationary objects
Due to the nature of the system, complicated
but non-critical driving situations may also
cause the autonomous braking function to inter- vene.
If the autonomous braking function demands
particularly high braking force, preventative
passenger protection measures (PRE-SAFE ®
)
are activated simultaneously (Y page 57).
Adaptive Brake Assist General notes
i Observe the "Important safety notes" sec-
tion (Y page 70).
With the help of Adaptive Brake Assist, the dis-
tance warning signal can detect obstacles that
are in the path of your vehicle for an extended
period of time.
If Adaptive Brake Assist detects a risk of a col-
lision with the vehicle in front, it calculates the 74
Driving safety systemsSafety

braking force necessary to avoid a collision. If
you apply the brakes forcefully, Adaptive Brake
Assist will automatically increase the braking
force to a level suitable for the traffic conditions.
Adaptive Brake Assist provides braking assis-
tance in hazardous situations at speeds above
7 km/h. It uses radar sensor technology to
assess the traffic situation.
Up to a speed of approximately 250 km/h,
Adaptive Brake Assist is capable of reacting to
moving objects that have already been detected
as such at least once over the period of obser-
vation.
Up to a speed of approximately 70 km/h, Adap-
tive Brake Assist reacts to stationary obstacles.
If Adaptive Brake Assist demands particularly
high braking force, preventative passenger pro-
tection measures (PRE-SAFE ®
) are activated
simultaneously (Y page 57).
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if: R you release the brake pedal
R there is no longer any danger of a collision
R no obstacle is detected in front of your vehicle
Adaptive Brake Assist is then deactivated.
Important safety notes i Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 70).G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
R intervene unnecessarily
R not 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. G
WARNING
Adaptive Brake Assist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when 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.
Due to the nature of the system, complicated
but non-critical driving situations may also
cause Adaptive Brake Assist to intervene.
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. Adaptive brake lights
The adaptive brake lights warn following traffic
in an emergency braking situation:
R by flashing brake lamps
R the hazard warning lamps are activated
If you brake sharply from a speed of more than
50 km/ hor if braking is assisted by BAS or BAS
PLUS, the brake lamps flash rapidly. In this way,
traffic travelling behind you is warned in an even more noticeable manner.
If you brake sharply from a speed of more than
70 km/h to a standstill, the hazard warning
lamps are activated automatically. If the brakes
are applied again, the brake lamps light up con- tinuously. The hazard warning lamps switch off
automatically if you travel faster than 10 km/h.You can also switch off the hazard warning
lamps using the hazard warning button
(Y page 124). ESP

(Electronic Stability Program)
General notes i
Observe the "Important safety notes" sec-
tion (Y page 70). Driving safety systems
75Safety Z

ESP
®
monitors driving stability and traction, i.e.
power transmission between the tyres and the
road surface.
If ESP ®
detects that the vehicle is deviating from
the direction desired by the driver, one or more
wheels are braked to stabilise the vehicle. The
engine output is also modified to keep the vehi- cle on the desired course within physical limits.
ESP ®
assists the driver when pulling away on
wet or slippery roads. ESP ®
can also stabilise
the vehicle during braking.
ETS/4ETS (Electronic Traction System) ETS traction control is part of ESP
®
. On vehicles
with 4MATIC, 4ETS is a component of ESP ®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is transfer-
red to the wheel or wheels with traction.
Traction control remains active if you deactivate
ESP ®
.
In appropriate driving situations, activate the
off-road programs:

rapidly approach a vehicle in front or a pedes-
trian
An intermittent warning tone will then sound
and the ·distance warning lamp lights up
in the instrument cluster.
X Brake immediately to defuse the situation.
or X Take evasive action provided it is safe to do
so. The PRE-SAFE
®
Brake 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
At a speed of up to approximately 70 km/h,
PRE-SAFE ®
Brake can also detect:
R stationary objects in the path of your vehicle,
e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
i If there is an increased risk of a collision,
preventive passenger protection measures
(PRE-SAFE ®
) are triggered (Y page 57).
If the risk of a collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking, up
to the point of full brake application. Automatic
emergency braking is not performed until imme- diately prior to an imminent accident.
You can prevent the intervention of PRE-SAFE ®
Brake at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal
