Driver assist systems -> ?Blind Spot? Monitor for Your Volkswagen E Golf 4 Door Second Generation (2017-2020)

“Blind Spot” Monitor  
Introduction to the topic  
Radar sensors monitor the area behind the vehicle. The system measures the distance and  
difference in speed in relation to other vehicles and uses visual signals in the wing mirrors to  
inform the driver.  
System limits  
Use the “Blind Spot” Monitor only on surfaced roads.  
The “Blind Spot” Monitor may not always interpret the traffic correctly in the following  
situations:  
In tight bends.  
When driving in the middle of two lanes.  
When road lanes are of varying width.  
At crests in the road.  
In poor weather conditions.  
Where there are special roadside structures, e.g. high or offset crash barriers.  
WARNING  
The intelligent technology used in the “Blind Spot” Monitor cannot overcome the physical limits  
specified, and functions only within the limits of the system. Never let the extra convenience  
afforded by the “Blind Spot” Monitor tempt you into taking any safety risks when driving.  
Careless or unintentional use of the “Blind Spot” Monitor can cause accidents and serious  
injuries. The system is not a substitute for the full concentration of the driver.  
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and  
traffic conditions.  
Your hands should always be on the steering wheel so that you can steer at any time.  
Pay attention to the indicator lamps in the wing mirrors and in the instrument cluster  
display and respond according to the commands.  
Always pay close attention to the surroundings of the vehicle.  
Never use the “Blind Spot” Monitor if the radar sensors are dirty, covered or damaged. These  
circumstances can impair the proper functioning of the system.  
It may be hard to see the indicator lamp in the wing mirror in direct sunlight.  
Some settings can be saved in the user accounts of the personalisation function and can  
therefore change automatically when the user account is changed (→ Personalisation,  
Description).

system (→ Vehicle settings menu, Operation).  
When the “Blind Spot” Monitor is operational the yellow indicator lamp in the wing mirrors  
lights up shortly one single time.  
This most recent system setting is retained even after the ignition has been switched off and on.  
Function  
When switched on, the “Blind Spot” Monitor is active from a speed of approx. 15 km/h (9 mph).  
In the following driving situations, the yellow indicator lamp will light up in the corresponding  
wing mirror  
Fig. 1 :  
If your vehicle is being overtaken.  
When overtaking another vehicle with a speed difference of up to approximately 10 km/h  
(6 mph). No display will be shown if the overtaking manoeuvre is much faster.  
If a vehicle is detected in the blind spot and the turn signal is additionally activated in the  
direction of the detected vehicle (→ Blind Spot Monitor, Introduction/General information), the  
yellow indicator lamp flashes  
.
In the case of vehicles with a lane keeping system, the yellow indicator lamp flashes even if  
you do not activate the turn signal when leaving your lane, provided that the lane keeping  
system is switched on (“Blind Spot” Monitor “Plus”). The driver is warned by a corrective steering  
intervention when changing lanes during a possible critical situation (information level, warning  
level). The steering intervention also occurs when the turn signal is activated for the  
corresponding direction. If the steering intervention is overridden by the driver, the steering  
wheel vibrates to give an additional warning.  
The faster another vehicle approaches, the earlier there is a corresponding display in the wing  
mirror.  
Automatic deactivation  
The radar sensors of the “Blind Spot” Monitor will switch off automatically if, for example, the  
system detects that a radar sensor is permanently covered. This can be caused by a layer of ice or  
snow in front of the radar sensor, for example.  
A text message will be shown on the instrument cluster display.  
If the “Blind Spot” Monitor has been automatically deactivated, the system cannot be activated  
until the ignition has been switched off and back on again.  
Troubleshooting  
“Blind Spot” Monitor failed  
The indicator lamp lights up yellow.  
Go to a qualified workshop.  
System fault  
Clean the radar sensors or remove stickers or accessories from the radar sensors, wing mirrors  
and bumper (→ Vehicle care, exterior, Cleaning/Care).  
Check whether any damage is visible.  
The system is not responding as expected  
This could have various causes:  
The radar sensors are dirty. The sensor visibility may be impaired by dirt and snow or also  
residue from cleaning agents or coatings (→ Vehicle care, exterior, Cleaning/Care).  
The prerequisites for system operation must be met (→ Blind Spot Monitor,  
Introduction/General information).  
The radar sensors are covered by water.  
The vehicle is damaged in the area of the radar sensors, e.g. caused by parking collisions.  
The detection ranges of the radar sensors are blocked by add-on parts, e.g. bicycle carriers.  
Changes have been made to the paintwork in the area of the radar sensors or structural  
modifications have been made, e.g. on the vehicle front end or the running gear.  
Only Volkswagen-approved vehicle paints may be used on the rear bumper. Other vehicle  
paints can restrict the function of the system or cause faults.  
The side windows have been retrofitted with tint films.
