Electronic Air Suspension and Terrain Response®

The air suspension can raise the ride height up to 125mm for extreme off-road use and also has an access mode that lowers the vehicle by 50mm for easier entry, exit and loading. The suspension delivers the most comfortable of rides. Its self-levelling feature yields outstanding handling and composure, working effortlessly with a wide range of vehicle loads. It also allows the vehicle height to be adjusted from outside the vehicle for trailer hitching, using the smart key buttons.
Land Rover’s patented Terrain Response® technology incorporates 60 years of our off-road expertise. The system optimises vehicle set-up for different terrain conditions and inspires supreme confidence over mud, gravel, grass, snow, and rocks, while delivering uncompromising performance on tarmac.
Terrain Response® also incorporates Sand Launch Control (SLC) and Rock Crawl (RC). Sand Launch Control helps prevent wheel spin and the vehicle ‘digging in’ when moving off from a standstill, while Rock Crawl delivers more vehicle composure by applying light brake forces.

Eight Airbags

Discovery 4 has up to eight airbags strategically positioned around the vehicle to thoroughly protect all occupants during an accident. The front seats have both front and side airbags, with each row having its own curtain airbags.

Push Button Start

Standard on all vehicles, Push Button Start works without the key being docked in the vehicle. The optional Keyless Entry System, when used with the remote Smart Key, provides even greater convenience. When close to the vehicle, simply open the door, enter, and push the Start button.

Hill Descent Control (HDC) with Gradient Release Control (GRC)

Land Rover’s patented Hill Descent Control (HDC) technology utilises the vehicle's ABS system to control the vehicle's downhill acceleration on a steep gradient. Gradient Release Control (GRC) is an additional function that further improves control over difficult descents. It does this by varying the brake pressure to achieve the desired acceleration, helping to compensate for changes in gradient.

Four-wheel Electronic Traction Control (ETC)

The four-wheel Electronic Traction Control (ETC) monitors individual wheel speeds and helps distribute drive to the wheels with the best grip. If a wheel starts to spin, ETC sends braking pulses to slow it down, improving its grip and boosting the torque applied to the opposite wheel to reduce vehicle speed.

Dynamic Stability Control (DSC)

Dynamic Stability Control improves the vehicle’s handling during acceleration or cornering. It also helps compensate for vehicle handling when towing a trailer. By constantly monitoring the wheels, it detects any deviation from the chosen line and immediately corrects it by applying braking to appropriate wheels.

Roll Stability Control (RSC)

Roll Stability Control works in conjunction with Dynamic Stability Control to help prevent vehicle roll-over. If the system senses that the vehicle is in danger of tipping, it will reduce engine power and use the ABS system to reduce the chance of roll-over.

Trailer Stability Assist (TSA)

Trailer Stability Assist (TSA) automatically detects the presence of a trailer. Once 37 mph is reached, the sensors monitor the behaviour of the trailer. Should any swaying or oscillation occur, the system uses selective braking of the appropriate wheels to help correct any potential problem.
