Blind Spot Assist

Warning: Blind Spot Assist is for visual aid only and does not replace the need for driver awareness. It is the driver’s responsibility to be aware of their surroundings and make sure it is safe to complete a lane change. Always make sure that there is a suitable distance to the side of your vehicle for other road users and obstacles.

Warning: The Blind Spot Assist system can not react to vehicles that approach and overtake you at a greatly different speed. In these situations, the Blind Spot Assist system cannot provide a warning to drivers. Always pay attention to the road traffic around you.
Blind Spot Assist is used to help a driver know if a vehicle is in their blind spot so that a lane change action can be safely completed.
The BSA system uses two rear-facing radar units to monitor the area up to 3.5 m (12 ft) behind your vehicle and 3 m (10 ft) directly next to your vehicle.
Aston Martin DBX 2021 Blind Spot Assist User Manual1

If a vehicle is detected at speeds above approximately 30 km/h (18 mph) and enters the monitoring range directly next to your vehicle, the warning lamp in the exterior mirror will illuminate amber. If a vehicle is detected close to your vehicle in the lateral monitoring range and you switch on the turn signal indicator in that direction the amber warning lamp in the outside mirror will flash. If the turn signal indicator remains on, all other detected vehicles are indicated only by the flashing of the amber warning lamp. If you overtake a vehicle quickly, no warning is given. The system can monitor vehicles when driving around curved roads.

Operation Conditions

For the Blind Spot Assist system to operate the below conditions must be met:

  • Transmission must be in D (Drive).
  • The vehicle must be moving at more than 30 km/h (18 mph).
  • Vehicles in the blind spot area must be traveling at speeds of:
  • More than 5 km/h (3 mph).
  • Between 5 km/h (3 mph) slower and 35 km/h (22 mph) faster than your vehicle.
  • The minimum width for a vehicle to be detected is 0.7 m wide (a motorcycle for example).

System Limitations
The BSA system can be limited in its operation in the below situations:

  • The sensors are dirty or obstructed such as snow or mud on the bumpers.
  • Poor visibility weather conditions (snow, fog, heavy rain etc).
  • Warnings may be incorrectly displayed near to crash barriers or long solid barriers.
  • Warnings can be interrupted when driving alongside long vehicles such as vehicles with long trailers.

System Activation
The BSA system can be activated or deactivated in the infotainment system (Refer to ’Assistance’, page 10.3).

Blind Spot Warnings

Stage One Warning
When the BSA system detects a vehicle in the driver’s blind spot area, an amber LED triangle (A) will be shown in the top outer corner of the door mirror.

Stage Two Warning
The BSA system will be set to stage two if:

  • A vehicle is detected in the blind spot area.
  • The indicator is used to signal movement into that lane.

When this happens, the below actions will take place.

  •  The amber triangle in the door mirror will flash.
  • A warning symbol will show in the instrument cluster (changes for the direction of lane change).

Door Exit Warning

Aston Martin DBX 2021 Blind Spot Assist User Manual2A door Exit Warning is available when the vehicle is stationary and the transmission is in P (Park) or D (Drive). The feature operates up to 3 minutes after the engine is off.
The Door Exit Warning function is a subfunction of the BSA system and detects if a vehicle or bicycle is passing that may come into contact with the door when it is opened. When the door is opened1 the BSA radars will check for any approaching vehicles. If there is a risk of collision, then audible warning will be heard as the door is opened. In addition, if a front door is opened then the BSA warning triangles will be illuminated in the door mirrors.

Fault Conditions

In the unlikely event of a fault in the BSA system, a warning message will also show in the instrument cluster. Contact your Aston Martin Dealer.

Lane Keep Assist

Safety Warnings

Warning: Lane Keep Assist may not always be able to correctly detect lane markings and it is possible it may give incorrect warnings. Lane Keep Assist is an aid only and does not replace the need for driver awareness. It is the driver’s responsibility to be aware of their surroundings. Always make sure that there is a suitable distance to the side of your vehicle for other road users and obstacles.

Warning: Lane Keep Assist cannot allow for road, traffic, and weather conditions. The driver is responsible for the vehicle’s speed, braking in good time, and staying within their lane.
Aston Martin DBX 2021 Blind Spot Assist User Manual2Lane Keep Assist is only available at speeds between 60 km/h (37 mph) and 200 km/h (125 mph).

Lane Keep Assist uses a multi-purpose camera and vehicle radar systems to detect lane markings in front of the vehicle. Lane Keep Assist will first warn if you leave your lane with a vibration through the steering wheel. If you do not react to the warning, the vehicle will briefly brake on one side to pull the vehicle back into the correct lane.

Steering Wheel Warning
If one of the front wheels passes over a lane marking, a warning will be given by an intermittent vibration from the steering wheel.
This warning can occur earlier, for example, if you begin to approach the other lane marking when on a bend or are on wider lanes such as a motorway.

Corrective Braking

Warning: Corrective brake application cannot always cause the vehicle to move back into it’s lane, which can cause an accident. Acceleration, steering and brake input should always be completed by the driver if when the vehicle uses corrective braking.

Warning: Lane Keep Assist does not allow for other road users and cannot detect traffic conditions. In some circumstances, the system may apply the brakes when not needed, such as driving over a solid lane marking or pulling out past an obstruction. Brake application in these circumstances can be interrupted by gently steering in the opposite direction. Always make sure that there is enough space for other traffic.
Aston Martin DBX 2021 Blind Spot Assist User Manual2Corrective braking will only take place after a steering wheel warning vibration.
Aston Martin DBX 2021 Blind Spot Assist User Manual2Corrective brake application will only happen once each time the vehicle leaves it’s an initial lane. Additional brake application will not happen again until the vehicle has returned to its initial lane.

If the vehicle continues to pass over the lane markings, the brakes will be briefly applied on one side. This is to help move the vehicle back to it’s initial lane. If this corrective braking happens, a warning icon will be shown in the instrument cluster. For the system to operate, lane markings must be on both sides of the vehicle. If broken lines are detected, corrective brake application will only happen if there is a vehicle in the next lane.

Corrective brake application will not happen in the below conditions:

  • There is clear and deliberate steering, braking or acceleration input.
  • A turn indicator is switched on.
  • The TPMS has detected a fault with a tire.
  • The traction control system is activated.
  • The transmission is not in D (Drive).
  • A trailer has been attached and electrically connected.
  • An obstruction has been detected in your lane.
  • Corners are taken at high speeds or high rates of acceleration where sudden brake application could unbalance the vehicle.

To cancel corrective brake application:

  • Activate the turn indicator.
  • Apply the brakes.
  • Accelerate.
  • Gently steer in the opposite direction.

Aston Martin DBX 2021 Blind Spot Assist User Manual2The Lane Keep Assist is set to on by default.
To deactivate Lane Keep Assist, press and hold the button (A).

The symbol will be shown in the instrument cluster to confirm the system has been deactivated.Aston Martin DBX 2021 Blind Spot Assist User Manual2

System Limitations
Lane Keep Assist may not function correctly in the below conditions:

  • The area around the multi-purpose camera is dirty, damaged or otherwise covered.
  • There is a short distance to the vehicle in front.
  • There are lots of lane markings that change quickly such as, merging or crossing lanes.
  • The road is very narrow and winding.
  • There are no lane markings or the markings are unclear in the lane, such as when the lane markings are worn away, a mix of old and new markings or many colour changes in road surface.
  • Weather conditions such as snow, rain, fog or spray which can cause low visibility or hide road markings. This can also include reflective roads surfaces due to rain.
  • Glare into the multi-purpose camera from the sun or other road users’ headlamps.
