Hard Braking Threshold 
The Hard Braking Threshold box in the 
Set Braking Thresholds
 dialog box is the lower of two braking 
thresholds in the CarChip Software.  
The default hard braking threshold for each standard measurement system is: 
• 
0.35 G - For U.S. measurement system. 
• 
0.35 G - For Metric measurement system. 
• 
3.4 m/s
2 
- For S.I. measurement system.

Set Braking Thresholds
 dialog box is the higher of two 
braking thresholds in the CarChip software.  
The default extreme braking threshold for each standard measurement system is: 
• 
0.50 G - For U.S. measurement system. 
• 
0.50 G - For Metric measurement system. 
• 
4.9 m/s

Set Acceleration Thresholds 
Use the Set Accelerations Thresholds dialog box to enter the rates of acceleration that define hard 
acceleration and extreme acceleration. These thresholds help you monitor how hard the vehicle is being 
accelerated. Any time the car's acceleration exceeds these set limits, the event is logged in the Trip 
Report. 
To set acceleration thresholds: 
1.  Select Set Acceleration Thresholds... from the CarChip menu. The 
CarChip / Set Acceleration 
Thresholds 
dialog box displays. 
 
2.  Enter your desired hard and extreme acceleration thresholds or click Default to use the software 
default threshold settings. The Default acceleration thresholds are: 0.30 and 0.45 G (US & Metric) 
and 2.9 and 4.4 m/s
 (S.I.). 
3.  Click OK to save the new settings. Click Cancel to exit the dialog box and retain the previous 
settings.
