Recognize Safety Information
This is a safety-alert symbol. When you see this symbol
on your machine or in this manual, be alert to potential for
personal injury.
Follow recommended precautions and safe operating
practices.
Items to Note Prior to Installation
• The following instructions are to be used only as a
supplement to the primary installation instructions
included with your AutoTrac Universal (ATU)
Steering kit.
• For additional vehicle specific information, including
hardware and recommended vehicle settings, please
visit www.StellarSupport.com to view or print
additional platform specific information.
• Several items are a part of the AutoTrac accuracy
equation. Please keep these external factors in mind
when installing components to provide the best
operating environment possible. (See AMS TALK
Bulletin # 043 and 048)
• Be aware that system may not perform well if you
have excessive wear in the steering linkage and
joints.
• Identification of worn and/or higher tolerance
steering components is vital for optimal performance
OUO6050,000128E –19–08SEP05–1/1
T81389 –UN–07DEC88
of the ATU kit. One method of checking wear, is to
turn the steering wheel and observe the movement
of the wheels. If the wheels don’t begin to turn when
the steering wheel is turned you may not achieve
optimal performance. Compare results with those of
a new vehicle of a similar model.
• Please refer to installation instructions included with
the GreenStar wiring harness and AutoTrac
Universal Steering kit for component location and
installation.
• Tighten all hardware that is installed to
manufacturer’s specifications.
IMPORTANT: AutoTrac Universal is to be installed
on approved platforms only. For a
complete list of approved platforms
please go to
www.stellarsupport.com.
Average Installation Time
• Approximate time needed for installing AutoTrac
Universal steering kit is less than 60 minutes. Total
amount of time needed may be greater if installing
GreenStar wiring harness and StarFire receiver
mounting brackets.
• For quicker installation, obtain AutoTrac Universal
activation code before proceeding to vehicle. (See
section on Activating AutoTrac Universal.)

(TY25683) and dry completely before attaching
adhesive clips.
2. After removing protective film on the clips, press and
hold the clips to the surface for at least 30 seconds to
ensure proper adhesion.
3. Securely lock all harnesses into clips leaving enough
slack for the steering wheel to telescope.

Activating AutoTrac Universal
AutoTrac Universal has to be activated by a 3-digit
activation code the first time that it is powered up. The
code can be attained by:
• Calling the AMS Customer Care Center at
1-888-GRN-STAR (888-476-7827).
• Logging onto www.stellarsupport.com and clicking on
the Activations and Subscriptions link on the left hand
menu. Once on this page click on Activate AutoTrac
Universal.
IMPORTANT: AutoTrac Universal system serial
number will be required to obtain
activation code.
After obtaining activation code: power up ATU unit, enter
the 3 digit activation code, and press SUBMIT.
Optional Use of Shims
• Included with your AutoTrac Universal Steering Kit are
shims that may be used to eliminate additional
movement in the vehicle’s steering console.
• The shims should only be used if optimal performance
can not be attained through changes in the vehicle
sensitivity settings.
• Install shims as needed as shown in photo.
IMPORTANT: Use of shims will eliminate the ability of
the steering column to telescope.
