2021 Aston Martin DBX Tyre Pressure Monitoring User Guide

This guide covers the 2021 Aston Martin DBX’s tyre pressure monitoring system, which optimizes performance and safety. Monitoring improves handling, fuel efficiency, and tyre life.

Tyre Pressure Monitoring System ( TPMS Guide )

Warning: Driving on a significantly under-inflated tyre causes the tyre to overheat and can lead to tyre failure. Over-inflation and under-inflation also reduce fuel efficiency and tyre tread life, and may affect the vehicle’s handling and stopping ability.

Warning: The TPMS is not a substitute for correct tyre maintenance, and it is the driver’s responsibility to maintain correct tyre pressures, even if under-inflation has not reached the level to set the TPMS tyre pressure indicator symbol to ON. A Tyre Pressure Monitoring System (TPMS) is installed as a safety feature. This system will display the tyre pressures for each tyre and provide warnings if pressure is below a specified pressure for each tyre.

Each tyre should be checked at least once every two weeks when cold, and inflated to the pressure recommended by the vehicle manufacturer (Refer to ’Wheel and Tyre Information’, page 11.15)or on the tyre pressure label. If your vehicle has tyres of a different size than the size indicated on the tyre pressure label, you should determine the proper tyre pressure for those tyres.

Tyre Pressure Display

Monitoring System Tutorial

The TPMS display is shown in the instrument cluster. Use the direction buttons on the right side of the steering wheel to navigate to Service and select Tyre Pressure. Tyre pressures will be displayed in the instrument cluster after the vehicle has been driven for a few minutes. If an under-inflated tyre is detected by the system, the TPMS symbol is solidly illuminated.

The message centre will also display one of the below messages:

  • Please Rectify Tyre Pressures: At least one tyre has too low a pressure. Tyre pressures should be checked and corrected when possible.
  • Check Tyre(s): At least one tyre has significantly low pressure. The tyre pressures must be checked and corrected as soon as possible.
  • Warning Tyre Defect: At least one tyre has lost pressure very suddenly. The vehicle should be stopped as safely as possible and the tyres checked.

Once the message has been acknowledged an image of the vehicle will be displayed in the message centre showing which tyre(s) have low or high air pressure and the current tyre pressure. When the tyre pressure indicator comes ON, stop and check your tyres as soon as possible, and inflate or deflate them to the correct pressure.

Warning: When a tyre pressure warning is detected, reduce the vehicle speed to a safe level. Stop in a safe and convenient place and inspect the tyre(s).
The tyre pressures may be displayed in the wrong positions for a short time if the wheels have been moved on the vehicle. After a few minutes of driving, the TPMS will calibrate and the tyre pressures are displayed in the correct positions.

2021 Aston Martin DBX TPMS Reset Owner’s Manual

All warning messages are erased and warning lamps go out when the TPMS is reset. The TPMS will use the new tyre pressure values as reference values.

To reset the TPMS tyre pressure values:

  1. Use the right scroll wheel on the steering wheel to navigate to Service.
  2. Navigate to Tyre Pressure.
  3. Select Use Current Pressures as New Reference Values.
  4. The TPMS will now reset. After a short period of driving, the system checks if the tyre pressures are within the specified range. The new tyre pressures are then used as the new reference values.

TPMS Malfunction Warning

If the TPMS malfunctions due to a system failure will flash for approximately one minute or tyre transmitter fault, and then remain lit. A malfunction of the tyre pressure monitor can take up to ten minutes to be shown. The TPMS warning lamp will go out when the fault has been resolved and after several minutes of driving.

A TPMS malfunction can be caused by:

  • A defective TPMS sensor.
  • Wheels and tyres installed that do not have Tire Pressure sensors.
  • Unapproved items interfering with the TPMS.
  • TPMS system or software fault.
  1. If the system shows there is a TPMS fault, continue at a reduced speed of 30mph / 48 km/h maximum. Contact your Aston Martin Dealer.

FAQ’s

What is the recommended tyre pressure for the 2021 Aston Martin DBX?

The recommended tyre pressure for the 2021 Aston Martin DBX is 34 PSI for the front tyres and 37 PSI for the rear tyres.

How does the Tyre Pressure Monitoring System (TPMS) work in the 2021 Aston Martin DBX?

The TPMS uses sensors to continuously monitor the air pressure in each tyre and alerts the driver if the pressure falls below the recommended level.

How often should I check the tyre pressure on my 2021 Aston Martin DBX?

It is recommended to check the tyre pressure at least once a month and before long trips to ensure optimal performance and safety.

What type of TPMS does the 2021 Aston Martin DBX use?

The 2021 Aston Martin DBX uses a direct TPMS, which measures the actual air pressure inside the tyres using sensors mounted on each wheel.

Is it safe to drive with the TPMS warning light on in the 2021 Aston Martin DBX?

It is not recommended to drive with the TPMS warning light on, as it indicates that one or more tyres may be under-inflated, which can affect vehicle handling and safety.
