WARNINGS
Information in this document is subject to change without notice. Ultra-Gauge.com reserves the right to change or improve its products
and to make changes in the content without obligation to notify any person or organization of such changes, additions or improvements.
Always visit Ultra-Gauge.com for the latest updates concerning the installation, use and operation of this product.
Failure to avoid the following potentially hazardous situations can result in an accident or
collision resulting in death or serious injury
INSTALLATION WARNINGS
When installing UltraGauge in your vehicle, place UltraGauge so that it does not obstruct the driver’s view of the road or ability
to operate the vehicle.
Extreme care must be taken when routing the OBD II cable. Avoid routing and installing in such a fashion that the cable can
interfere with any of the foot controls, steering wheel, or other vehicle controls, or represent an entry or exit hazard to the driver.
Always secure excess or loose cable so that feet and hands do not become entangled.
The windshield mount or Velcro mount may not stay attached under all conditions. Do not mount UltraGauge where it will
become a distraction or hazard should it become detached.
Do not mount UltraGauge in an area that may interfere with the deployment of airbags. Consult your vehicles owner’s manual.
UltraGauge in rare circumstances may impair select vehicle systems. See the Forced Protocol section for more information and
resolution.
Tightening the windshield mount locking ring will result in increased force necessary to adjust the position of UltraGauge and if
over tightened may result in damage. The ring should be adjusted so that the ball swivel offers a very slight resistance to
movement.
OPERATION WARNINGS
Never attempt to operate UltraGauge controls while the vehicle is moving. Not only is this extremely hazardous, UltraGauge
stops performing mileage, distance and other calculations while the menu system is active.
Never become distracted by UltraGauge while driving.
Liability
The use of UltraGauge is at your own risk. Ultra-Gauge.com shall in no event be liable for any damages, whether direct or indirect,
special or general, consequential or incidental, arising from any loss claimed as a result of the use of UltraGauge.
Battery Warning
This product contains no batteries
Fuse Warning
This product is equipped with a fuse. The fuse is integrated in the male OBD-II connector and cannot be accessed or replaced.
This fuse provides protection against potential short-circuit conditions within UltraGauge and short-circuits introduced into the
cable.

Display Cleaning
The display has a polarizing film over the glass. This film is very easily scratched and damaged.
UltraGauge is shipped with a protective plastic film over the display to keep it clean. Many opt to leave the protective plastic film in
place to protect the display.
Unless the display is very dirty, avoid cleaning the display
The display can be cleaned, but requires extreme caution. We recommend a mild soap or 90% isopropyl alcohol as the cleaning agent.
Isopropyl alcohol has the advantage that it evaporates quickly and leaves no film behind. Only use a very soft cleaning tissue such as
toilet paper or facial tissue such as Kleenex. Use very light pressure when cleaning. Such soft tissue tends to leave fibrous debris
clinging to the display. Use a clean micro fiber cloth to lightly dust the surface. While dusting the surface blow against the surface to
wisk away the debris.

Display will remain on while in the menu system. Always exit the menu system when the ignition is in the OFF position.
Installation
The Basic installations steps are as follows:
1. Choose method of mounting; Custom, Hook & Loop, vertical, horizontal or windshield mount
2. Install the mount
3. Attach UltraGauge to the mount
4. Optionally coil extra cable near UltraGauge to allow UltraGauge to be disconnected from mount and conveniently
configured
5. Route the remainder of the cable such that it is tucked away and does not interfere with vehicle controls, such as steering,
wiper control, transmission shifter, turn signal, foot controls, and does not represent a hazard to vehicle entry or exit.
6. Turn the ignition to the RUN position. (The ignition has four positions: OFF, ACC, RUN & START. You do not need to
start the vehicle)
7. Connect the UltraGauge OBD II connector to the OBD II connector on the vehicle
8. UltraGauge will then determine the vehicle’s protocol and discover the available gauges.
Detailed Installation instructions
Choose method for mounting; Hook & Loop, vertical, horizontal or windshield mount. The Hook & Loop mount has the
advantage that it can be used to attach in areas less visible from outside the vehicle, reducing the risk of vandalism and theft.
The Hook & Loop mount is also less likely to lose attachment over time and is inherently less obstructive.
The windshield mount has the advantage that it typically positions UltraGauge in an area that is closer to the view of the road
and hence potentially represents less interruption to driving concentration. The windshield mount can also be attached to any
smooth surface and is therefore not limited to the windshield.
Hook & Loop
The hook and loop fastener, commonly known as Velcro™, is comprised of two halves, each is 1"x1.5". One half is attached to the back
of UltraGauge, as shown above. The 2nd half is attached to a surface inside the vehicle, such as the dash. The fastener may be used as-is
or trimmed in size or cut in to several pieces. Each half has an adhesive that can be applied to any clean, solid surface. The fastener is
an industrial strength Hook & Loop which can withstand temperatures as high as 250F (121C) without lifting or shearing from the
attached surface.
