2018 MERCEDES-BENZ GLA SUV brake

EBD (electronic brake force distribu-
tion)
General information
EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 60).
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
Please observe the information on warning and
indicator lamps (
Ypage 230)
(
Ypage 230) as well as on display messages
(Ypage 203).
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety and
offers increased braking comfort. In addition to
the braking function, ADAPTIVE BRAKE also has
the HOLD function (
Ypage 162) and hill start
assist (Ypage 127).
STEER CONTROL
General information
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel
in the direction required for vehicle stabilization.
This steering assistance is provided in particular if:
Rboth right wheels or both left wheels are on a
wet or slippery road surface when you brake
Rthe vehicle begins to skid
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 60).
No steering assistance is provided from STEER
CONTROL, if:
RESP®is malfunctioning
Rthe steering is malfunctioning
If ESP®is malfunctioning, you will be assisted
further by the electrical power steering.

Windshield wipers
Switching the windshield wipers
on/off
!
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.

Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehiclehas been delivered or after repairs. Full system
effectiveness is not reached until the end of this
teach-in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after several hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its per-
formance in the future.
RYou should therefore drive at varying vehicle
and engine speeds for the first 1000 miles
(1500 km).
RAvoid heavy loads, e.g. driving at full throttle,during this period.
RChange gear in good time, before the tach-
ometer needle is Ôof the way to the red area
of the tachometer.
RDo not manually shift to a lower gear to brake
the vehicle.
RTry to avoid depressing the accelerator pedal
beyond the point of resistance (kickdown).
RIdeally, for the first 1000 miles (1500 km),
driv ein progra mE.
Addition al breaking-in notes for Mercedes-AMG
vehicles:
RDo not drive faster than 85 mph (140 km/h)
for the first 1,000 miles (1,500 km).
ROnly allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
RChange gear in good time.
After 1,000 miles (1,500 km), you can increase
the engine speed gradually and bring the vehicle
to full speed.
You should also observe these notes on break-
ing-in if the engine or parts of the drive train on
your vehicle have been replaced.
Always observe the maxim
um permissible
speed.
Driving
Important safety notes
GWARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
GWARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
Rshoes with thick soles
Rshoes with high heels
Rslippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
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.

!Do not warm up the engine while stationary.
Pull away immediately. Avoid high engine
speeds and full throttle until the engine has
reached its operating temperature.
In vehicles with automatic transmission,
engage positions P and R only when the vehi-
cle is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
!Mercedes-AMG vehicles: avoid full-load
operation and engine speeds greater than
5000 rpm when the engine is cold. This helps
to protect the engine and avoids uncomfort-
able driving.

Start/Stop button
General notes
Vehicles with KEYLESS-GO are equipped with
SmartKeys featuring the integrated KEYLESS-
GO function and a detachable Start/Stop but-
ton. A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example, when
starting the engine.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different Smart-
Key positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
To start the vehicle without actively using the
SmartKey:
Rthe Start/Stop button must be inserted in the
ignition lock
Rthe SmartKey must be in the vehicle
Rthe vehicle must not be locked with the
SmartKey or KEYLESS-GO (Ypage 70)
Do not keep the KEYLESS-GO key:
Rwith electronic devices, e.g. a mobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of KEYLESS-GO.
If you lock the vehicle with the SmartKey remote
control or with KEYLESS-GO, after a short time:
Ryou will not be able to switch on the ignition
with the Start/Stop button.
Ryou will no longer be able to start the engine
with the Start/Stop button until the vehicle is
unlocked again.
If you lock the vehicle centrally using the button
on the front door (
Ypage 75), you can continue
to start the engine with the Start/Stop button.
The engine can be switched off while the vehicle
is in motion by pressing and holding the Start/
Stop button for three seconds. This function
operates independently of the ECO start/stop
automatic engine switch-off function.
