2019 MERCEDES-BENZ GLA warning light

The rate of vehicle deceleration or accelera-tion and the direction of the force are essen-tially determined by:
Rthe distribution of forces during the collision
Rthe collision angle
Rthe deformation characteristics of the vehi-cle
Rthe characteristics of the object with whichthe vehicle has collided
Factors which can only be seen and measuredafter a collision has occurred do not play adecisive role in the deployment of an air bag.Nor do they provide an indication of air bagdeployment.
The vehicle can be deformed considerably,without an air bag being deployed. This is thecase if only parts which are relatively easilydeformed are affected and the rate of deceler-ation is not high. Conversely, air bags may bedeployed even though the vehicle suffers onlyminor deformation. This is the case if, forexample, very rigid vehicle parts such as longi-tudinal body members are hit, and sufficientdeceleration occurs as a result.
If the restraint system control unit detects aside impact or if the vehicle rolls over, theapplicable components of the restraint systemare deployed independently of each otherdepending on the apparent type of accident.
RSide impact air bags on the side where theimpact takes place, independently of theEmergency Tensioning Device and the useof the seat belt on the driver's seat andouter seats in the second row
The side impact air bag on the frontpassenger side deploys under the followingconditions:
-the OCS system detects that the frontpassenger seat is occupied or
-the seat belt buckle tongue is engaged inthe belt buckle of the front passengerseat
RWindow curtain air bag on the side ofimpact, independently of the use of the seatbelt and independently of whether the front-passenger seat is occupied
REmergency Tensioning Devices, if the sys-tem determines that deployment can offeradditional protection in this situation
RWindow curtain air bags on the driver's andfront-passenger side in certain situationswhen the vehicle rolls over, if the system
determines that deployment can offer addi-tional protection to that provided by theseat belt
iNot all air bags are deployed in an acci-dent. The different air bag systems workindependently of each other.
How the air bag system works is determinedby the severity of the accident detected,especially the vehicle deceleration or accel-eration and the apparent type of accident:
RHead-on collision
RSide impact
RRollover
Automatic measures after an acci-
dent
Immediately after an accident, the followingmeasures are implemented, depending on thetype and severity of the impact:
Rthe hazard warning lamps are switched on
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rthe engine is switched off and the fuel sup-ply is cut off
Rvehicles with Mercedes me connect: auto-matic emergency call
Children in the vehicle
Important safety notes
Accident statistics show that children securedin the rear seats are safer than childrensecured in the front-passenger seat. For thisreason, Mercedes-Benz strongly advises thatyou install a child restraint system on a rearseat. Children are generally better protectedthere.
If a child younger than twelve years old andunder 5 ft (1.50 m) in height is traveling in thevehicle:
Ralways secure the child in a child restraintsystem suitable for Mercedes-Benz vehicles.The child restraint system must be appropri-ate to the age, weight and size of the child.
Rbe sure to observe the instructions andsafety notes in this section in addition to the

child restraint system manufacturer's instal-lation instructions.
Ralways observe the instructions and safetynotes on the "Occupant classification sys-tem (OCS)". (Ypage 47)
GWARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
Rrelease the parking brake.
Rshift the automatic transmission out of
the parking positionP.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Never leave children unsupervised in the
vehicle.
GWARNING
If persons, particularly children are subjec-
ted to prolonged exposure to extreme heat
or cold, there is a risk of injury, possibly
even fatal. Never leave children unattended
in the vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight.
Protect it with a blanket, for example. If the
child restraint system has been exposed to
direct sunlight, let it cool down before secur-
ing the child in it. Never leave children unat-
tended in the vehicle.
Always ensure that all vehicle occupants havetheir seat belts fastened correctly and are sit-ting properly. Particular attention must be paidto children.
Observe the safety notes on the seat belt(Ypage 41) and the notes on correct use ofseat belts (Ypage 42).
A booster seat may be necessary to achieveproper seat belt positioning for children over40 lbs (18 kg) until they reach a height wherea three-point seat belt can be properly fas-tened without a booster seat.
Special seatbelt retractor
GWARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt
retractor is disabled and the inertia real
draws in a portion of the seat belt. The seat
belt cannot be immediately refastened.
There is an increased risk of injury, possibly
even fatal.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reacti-
vate the special seat belt retractor and
secure the child restraint system properly.
All seat belts in the vehicle, except the driver'sseat belt, are equipped with a special seat beltretractor. When activated, the special seat beltretractor ensures that the seat belt cannotslacken once the child seat is secured.
Installing a child restraint system:
XMake sure you observe the child restraintsystem manufacturer's installation instruc-tions.
XPull the seat belt smoothly from the beltoutlet.
XEngage seat belt tongue in belt buckle.
Activating the special seat belt retractor:
XPull the seat belt out fully and let the inertiareel retract it again.While the seat belt is retracting, you shouldhear a ratcheting sound. The special seatbelt retractor is enabled.
XPush the child restraint system down so thatthe seat belt is tight and does not loosen.

Driving safety systems
Overview of driving safety systems
In this section, you will find information aboutthe following driving safety systems:
RABS (Anti-lockBrakingSystem)(Ypage 60)
RBAS (BrakeAssistSystem) (Ypage 61)
RActive Brake Assist (Ypage 61)
RESP®(ElectronicStabilityProgram)(Ypage 63)
REBD (ElectronicBrake forceDistribution)(Ypage 67)
RADAPTIVE BRAKE (Ypage 67)
RSTEER CONTROL (Ypage 67)
Important safety notes
If you fail to adapt your driving style or if youare inattentive, the driving safety systems canneither reduce the risk of an accident noroverride the laws of physics. Driving safetysystems are merely aids designed to assistdriving.
You are responsible for maintaining the dis-tance to the vehicle in front, for vehicle speed,for braking in good time, and for staying inlane. Always adapt your driving style to suitthe prevailing road and weather conditions andmaintain a safe distance from the vehicle infront. Drive carefully.
The driving safety systems described onlywork as effectively as possible when there isadequate contact between the tires and theroad surface. Please pay special attention tothe notes on tires, recommended minimumtire tread depths, etc. (Ypage 305).
In wintry driving conditions, always use wintertires (M+S tires) and if necessary, snowchains. Only in this way will the driving safetysystems described in this section work aseffectively as possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a waythat the wheels do not lock when you brake.
This allows you to continue steering the vehi-cle when braking.
The%ABS warning lamp in the instrumentcluster lights up when the ignition is switchedon. It goes out when the engine is running.
ABS works from a speed of about 5 mph(8 km/h), regardless of road-surface condi-tions. ABS works on slippery surfaces, evenwhen you only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-tion (Ypage 60).
GWARNING
If ABS is malfunctioning, the wheels could
lock when braking. The steerability and
braking characteristics would be severely
affected. There is an increased danger of
skidding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,including driving safety systems, will alsobecome inoperative. Observe the informationon the ABS warning lamp (Ypage 233) anddisplay messages which may be shown in theinstrument cluster (Ypage 204).
Braking
XIf ABS intervenes:continue to depress thebrake pedal vigorously until the braking sit-uation is over.
XTo make a full brake application:depressthe brake pedal with full force.
If ABS intervenes when braking, you will feel apulsing in the brake pedal.
The pulsating brake pedal can be an indicationof hazardous road conditions, and functions asa reminder to take extra care while driving.
Off-road ABS
An ABS system specifically suited to off-roadterrain is activated automatically once the off-road program is activated (Ypage 170).
At speeds below 20 mph (30 km/h), the frontwheels lock cyclically during braking. The dig-ging-in effect achieved in the process reduces
