    ** Approximate heights.

    Towbars
    Centrally mounted, semi-undermounted and undermounted towbars for centre-axle trailers. Towbars can be fitted at intervals of 25 millimetres.

    Fuel tanks
    Aluminium or steel tanks in volumes from 150 to 900 litres. Maximum fuel volume is 1480 litres for a 4×2 tractor.

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

    Fifth wheels
    Certified installation permits up to 36 tonnes load. An ISO fifth wheel with L-shaped profiles at different heights is included in the range, offering considerable freedom of choice. The flange-mounted fifth wheel is a low-weight variant since it does not require any attachment plate. The fifth wheel’s height above the chassis is from about 140 millimetres. Integrated lubrication and trailer connection indicator is available as option for specific variants.

    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.

    Volvo Dynamic Steering is now available for all axle configurations, including trucks with dual front axles.

    Tandem Axle Lift
    Allows the rearmost drive axle on the tandem bogie to be disengaged and raised, to reduce fuel consumption and turning radius. By pushing a button on the dashboard, the driver can raise the axle when the truck is unloaded. When the truck is loaded, the axle automatically lowers itself and engages. 

    Tandem Axle Lift is available for 6×4 and 8×4 configurations (with a tandem bogie) equipped with disc brakes.

    Tag axles
    Available in several configurations – fixed with single or dual wheels, self steered or actively steered. Axle load: 7.5, 9.5 or 10 tonnes.

    Pusher axles
    Available in fixed and actively steered variants for both tractors and rigids. Axle load: 7.5 or 9 tonnes.

    Brakes

    EBS (Electronically-controlled Brake System) provides superior response, performance and brake feel, while providing access to a number of handy features. EBS is now available both for disc brakes and Z-cam drum brakes (for a selected range of axle configurations and chassis heights). Upgrade your brake system by adding the EBS Medium package or any of the additional options.

    EBS MEDIUM

    In addition to the EBS Standard package, EBS Medium adds the following features.

    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. (Only for disc brakes.)

    Automatic Parking Brake Release

    The parking brake is released when the driver pushes the accelerator pedal and a gear is selected (only I-Shift gearbox).

    ADDITIONAL OPTIONS

    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.

    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, and is available for 2- and 3-axle vehicles.

    Emergency Brake Light

    When panic braking from speeds above 50 km/h, the brake lights flash with four flashes per second.

    Hydraulic retarder

    Gearbox-mounted compact retarder with a max effect of 440 kW.
