Quick Overview:
Congratulations, on your XLifter purchase! I am so glad you decided to read the
instructions. Many users casually dismiss instructions and seek to figure it out on their
own – which is perfectly possible, however, even though I’ve built the product as simple
and intuitive as possible, there are some useful tricks, hints, warnings and “behind the
scenes” info that’s worth a read.
Chapter 4 is all about installation, skip it if the XLifter is already installed.
The most important is chapter 5 - Instruction for use, where the XLifter daily-use
functions are described. Please consider reading it again after a few days of hands-on
experience.
Thank you for your trust in XLifter and have a great experience.

2. General description
XLifter is an advanced air-suspension controller for specified Land Rover vehicles. XLifter
allows you to take the air suspension capabilities of your Land Rover to the maximum,
making your off-roading or expedition travelling a greater experience.
XLifter gives you more detailed control over the vehicle height settings. Raising the vehicle
above the maximum specified (By Land Rover) “Off-road” height, helps you to tackle difficult
terrain. XLifter is not limited by the 40 Km/h speed limit, therefore travelling over long
stripes of sand, green lanes or gravel roads will be more manageable. Also, XLifter keeps
selected lift settings archived, which means that you can keep it as a selected height
constantly should you wish to. Lowering the vehicle, slightly, improves cornering stability
and aerodynamics (which may add to fuel consumption efficiency). Lowering below the
original access height makes it possible for the entering of low-clearance garages or ferries
and makes cargo loading easier.
XLifter’s unique self-levelling feature makes your in-car or roof top tent conditions more
comfortable during expedition travelling.
XLifter controls are intuitive and comfortable. The control module with graphical OLED
display and physical buttons is optimized for off-road handling.
XLifter EAS unit communicates with the control module wirelessly. Installation to your
vehicle is simple and fully removable when required. No drilling, soldering, or in-car wiring
is required.
XLifter is designed for Land Rover® Discovery 3 (LR3), Discovery 4 (LR4) and Range
Rover® Sport (model L320) vehicles. Range Rover® L322 2007-2012 support is currently
experimental (in development).

3. Safety information
This manual contains important information on the installation and use of the XLifter.
Please take some time to read this section to fully utilise the XLifter features and to ensure
that you know how to operate it safely. Use the XLifter only for its intended purpose as
described in this user manual.
What the safety symbols in this user manual mean:
This symbol represents potential general warnings, hazards or unsafe practices
that may result in possible damage to vehicle or vehicle systems. Please read texts
marked by this symbol carefully and proceed according to provided
instructions to avoid risks.
Warning: This symbol, with the word "warning" attached above or next to the
symbol, indicates situations where non-compliance may result in serious injury or
damage to the equipment or vehicle.
Safety instructions are described on a continuous basis in the description of each XLifter
function. However, below is an overview of the most important ones:
General warnings:
Warning: Ensure that the XLifter is operated only by a person familiar with this manual. If
another person is driving, please activate the Keylock function before driving, as a safety
measure. (see chapter 5.4)
Warning: If an XLifter is left installed in the vehicle when it is sold, notify the new acquirer
and familiarize him with this manual. Please keep this manual in the vehicle in an
accessible location for a future reference.
Warning: Do not use XLifter while driving on the public roads. Do not lower or raise the
vehicle at high speeds.
Warning: When using the XLifter mobile application, same warnings applies. There is no
difference when you control the XLifter from the control module or mobile app
Warnings for the lifter and lifer-free functions:
Warning: Don’t overstress the CV joints when in extreme lifts - “Sky Rocket” (+75 mm) or
any lift program while the “original” vehicle height is engaged in Off Road. Be gentle with
the accelerator pedal when you have low-range engaged and you are steering
excessively to the left or right with.
Warning: In the original “Off Road” vehicle height, it is not recommended to lift the vehicle
with XLifter by more than +25 mm permanently due to possible increase wear of the air-
springs.
Warning: Be gentle to the vehicle compressor! The compressor will overheat when the
vehicle is lowered/raised several times (3x is enough) in a row. When overheated to approx.
130 °C, the Land Rover EAS unit inhibit further operation until cooled down. Cooling takes
about 10 minutes. Watch the compressor temperature!
Warning for the levelling function:
Warning: NEVER start the levelling function while driving. The wheels height will be set
differently, which results to potentially dangerous situation. Start levelling ONLY when the
vehicle is stationary.
When active, the levelling function must be exited before driving. Otherwise you start
driving with unbalanced wheel heights, exposing yourself to potentially dangerous
situations and you may even damage your vehicle. NEVER leave the camping place with
levelling still active!
Do not engage electronic park break (EPB) before or during levelling. It will cause
unnecessary tension on the park brake cables, which will counteract wheel movement.
You may use the features in park mode without the brake engaged.
Warning: Close all doors before starting the levelling function to prevent possible damage
due to contact with surrounding obstacles/obstructions.

4. Installation
4.1. Package Contents

4.2. Installation - General Description and Overview
The XLifter device consists of 2 main components - the control module and the EAS
installation unit (EAS stands for Electronic Air Suspension). The control module (display unit
with buttons) is used to control all settings and to inform the user of the operating status.
The EAS unit serves to adjust the wheel height sensor signals and vehicle tilt
measurements. Communication of the control module and the EAS unit is wireless.
The control module can be placed anywhere in the interior of the vehicle that allows for
easy accessibility – as per user preference. The control module needs to be connected to an
12V power supply (cigarette lighter socket). Advanced users may cut the power connector
and connect the cable to appropriate 12V junction point. Installation with all cables hidden
will look more aesthetically pleasing and the lighter socket will not be blocked by the
plugged-in unit.
The XLifter EAS unit is installed near the original air suspension control unit and connects
with it via the supplied cable harness. The XLifter EAS unit is mechanically attached to the
body of the vehicle after installation, thus serves also as an accurate tilt sensor.
