CarDAQ-Plus

Quick Start Guide

2

CarDAQ-Plus has been carefully designed and tested to comply with OBDII
protocols, which are used on most 1996 and newer cars and light trucks sold in
the USA. However, some vehicle models are not in full compliance with these
protocols for various reasons. In addition, the computer control systems or
sensors on any given vehicle may be malfunctioning or out of specification.

Note: Vehicles manufactured for use outside of the USA may not comply with
OBDII protocols, even though an SAE J1962 connector is located in the
vehicle. Connection to vehicles manufactured for use outside of the USA is AT
YOUR OWN RISK. Drew Technologies will not be held responsible for ANY
direct, indirect or consequential damage that arises as a result of connecting to
such a vehicle.

Before installing CarDAQ-Plus, we recommend visiting this website for service
information: www.nastf.org.

While Drew Technologies testing and the experience of thousands of CarDAQ­Plus users have shown the interface to be safe and reliable, there is an
inherent risk in using any product that may potentially affect the operation or
drive-ability of your vehicle. Drew Technologies will not be held responsible for
ANY direct, indirect or consequential damage that arises as a result of using
CarDAQ-Plus on a vehicle.

If you are concerned about the operation of your vehicle at any time while using
CarDAQ-Plus:

• If you are driving, pull off the roadway immediately or as soon as it is
safe to do so.

• Disconnect CarDAQ-Plus from the OBDII port.

• Consult a licensed mechanic or automobile service center.

Report any issues or concerns to our Technical Support Dept. at
[e-mail]. We are open Monday through Friday, 9:00 a.m. to
5:30 p.m. Eastern Time. We maintain an active database of the feedback we
receive, and your comments can help us continuously improve the product.
