2017 MERCEDES-BENZ GLS-Class SUV instrument cluster

It may be best to deactivate ESP®in the follow-
ing situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
Spinning the wheels results in a cutting action
which provides better grip.
iActivate ESP®as soon as the situations
described above no longer apply. ESP®will
otherwise not be able to stabilize the vehicle if the vehicle starts to skid or a wheel starts to
spin.
!Avoid spinning the driven wheels for an
extended period with ESP®deactivated. You
could otherwise damage the drivetrain.
Deactivating/activating ESP®
XTo deactivate: press button:.

instrument cluster lights up.
XTo activate: press button :.
The å ESP®OFF warning lamp in the
instrument cluster goes out.
Characteristics when ESP®is deactivated
If ESP®is deactivated and one or more wheels
start to spin, the ÷ESP®warning lamp in the
instrument cluster flashes. In such situations,
ESP
®will not stabilize the vehicle.
If you deactivate ESP®:
RESP®no longer improves driving stability.
REngine torque is no longer limited and the
drive wheels are able to spin.
RTraction control is still activated.
RActive Brake Assist is no longer available; nor
is it activated if you brake firmly with assis-
tance from ESP
®
RPRE-SAFE®is no longer available, nor is it
activated if you brake firmly and ESP®inter-
venes.
RActive Brake Assist with cross-traffic function
is no longer available; it is not activated even
if you brake firmly with assistance from ESP
®
RESP®still provides support when you brake
firmly.
Offroad ESP®(vehicles with Offroad
Engineering package)
An ESP®system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated on:
RVehicles without the Offroad Engineering
package (Ypage 217)
RVehicles with the Off-Road Engineering pack-
age (Ypage 218)
Offroad ESP®intervenes with a delay if there is
oversteering or understeering, thus improving
traction.
ESP®trailer stabilization
General information
ESP®trailer stabilization is not available in
Mercedes-AMG vehicles.
If your vehicle/trailer combination begins to
swerve, 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 stabilized.
Important safety notes
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.
If your vehicle with trailer (vehicle/trailer com-
bination) begins to lurch, you can only stabilize
the vehicle/trailer combination by depressing
the brake firmly.

Rdarkness
Ror if:
-pedestrians move quickly, e.g. into the path
of the vehicle
-the camera system no longer recognizes a
pedestrian as a person due to special cloth-
ing or other objects
-a pedestrian is concealed by other objects
-the typical outline of a person is not distin-
guishable from the background
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensors 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.
Following damage to the windshield, have the
configuration and operation of the camera sys-
tem checked at a qualified specialist workshop.
Function
XTo activate or deactivate: activate or deac-
tivate Active Brake Assist with cross-traffic
function using the on-board computer
(
Ypage 237).
If the Active Brake Assist with cross-traffic
function is deactivated, the æsymbol
appears in the multifunction display.
If you have activated DSR (
Ypage 216), the
Active Brake Assist with cross-traffic function is
deactivated.
Starting at a speed of around 4 mph (7 km/h),
this function warns you if you rapidly approach a
vehicle in front. An intermittent warning tone
will then sound and the ·distance warning
lamp will light up in the instrument cluster.
XBrake immediately to defuse the situation.
or
XTake 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:
Rthe driver and front-passenger have their seat
belts fastened
and
Rthe vehicle speed is between approximately
4 mph (7 km/h) and 124 mph (200 km/h) Up to a speed of approximately 44 mph
(70 km/h), Active Brake Assist with cross-traffic
function may react to:
Rstationary objects in the path of your vehicle,
e.g. stopped or parked vehicles
Rpedestrians in the path of your vehicle
iIf there is an increased risk of a collision,
preventive passenger protection measures
(PRE-SAFE
®) are triggered (Ypage 55).
If the risk of 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.
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 brak
e pres-
sure up to full brake application.
To avoid a collision, Active Brake Assist with
cross-traffic function calculates the brake force necessary if:
Ryou approach an obstacle, and
RActive Brake Assist with cross-traffic function
has detected a risk of a collision
When driving at a speed
under20 mph(30 km/h): if you depress the
brake pedal, Active Brake Assist with cross-traf-
fic function is activated. The increase in brake
pressure from Active Brake Assist with cross-
traffic function is carried out at the last possible
moment.
When driving at a speed
above20 mph(30 km/h): if you depress the
brake pedal sharply, Active Brake Assist with
cross-traffic function automatically 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 4 mph (7 km/h) and 155 mph
(250 km/h).

Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (
Ypage 239).
It is only possible to shift the transmission from
position Pto the desired position if you depress
the brake pedal. Only then is the parking lock
released. If you do not depress the brake pedal,
the DIRECT SELECT lever can still be moved but the parking lock remains engaged.
iUpshifts take place at higher engine speeds
after a cold start. This helps the catalytic con-
verter to reach its operating temperature
more quickly. Information on the automatic release of the
electric parking brake (
Ypage 161).
Pulling away with a trailer
To ensure that you do not roll backwards when
pulling away on an uphill slope, engage the elec-
tric parking brake.
XPress and hold handle

the electric parking brake is released.
The red F(USA only) or !(Canada
only) indicator lamp in the instrument cluster goes out.
Hill start assist
Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. It holds
the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and to
depress it before the vehicle begins to roll.
GWARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
