AdBlue tanks

Plastic. Volumes from 32 to 90 litres. The AdBlue pump is integrated in the AdBlue tank module.

Volvo Dynamic Steering

Active steering system with torque overlay. Delivers more steering force at low speeds, reduces steering kicks and keeps the steering wheel straight forward when braking on split friction. The steering wheel returns automatically to neutral position both when driving forward and when reversing.

Available for tractors and rigids 4×2, 6×4 or 8×4 with single front axle.


Volvo EBS (Electronically controlled Brake System) disc brakes are available with program package MED for rigids and tractors. ESP is available for tractors and rigids with 4×2, 6×2 and 6×4 drive. The brake range also includes Volvo Z-cam drum brakes with ABS (Anti-lock Braking System).

EBS Status Control
EBS status monitoring via the TEA2+ vehicle electronic system and Volvo Tech Tool.

Hill Start Aid
The brakes are only released once there is sufficient engine torque to propel the vehicle forward.

Lining Wear Analysis
Brake lining warning – calculates the remaining mileage available with the current brake linings.

In addition to the program packages there are the following options:

Stretch Brake
Enables the driver to request pulse braking of the trailer. The brake is then automatically activated and the risk of jack-knifing is minimised. Only for rigids.

ESP (Electronic Stability Program)
The brake stability system applies the brakes individually on each wheel, thereby providing stability for the entire vehicle combination and counteracting jack-knifing, rollover and trailer swing. ESP fulfils the legislation of Electronic Vehicle Stability Control.
