PRE-TRIP INSPECTION AND DAILY MAINTENANCE
Pre-Trip Assistant
The Pre-Trip Assistant option is a tool to
assist the driver in completing the pre-
trip inspection of the vehicle. Use this
feature via the Driver Information Display
(DID). This option is not a substitute for a
complete pre-trip inspection. If any
system of the vehicle does not pass
inspection, the problem must be
corrected before operating the vehicle.
The following tests are available:
• Activate Exterior Light Inspection
Test; Allows the driver to perform
system controlled test of the
vehicle's lighting systems.
• Light Switch Test Check List; Allows
the driver to physically activate each
switch. If the switch operates
properly it is noted on the Switch
Test DID screen.
• Air Brake Leak-Down Test; Allows
the driver to check the air system for
leaks. Any leaks are noted on the
Leak-Down Test DID screen.
NOTE
The Hazard and High/Low beam switches
are momentary switches and return to the
OFF position when released during
testing.

The Activate Exterior Light
Inspection Test repeatedly turns all
exterior lights ON/OFF for the
vehicle. This check allows the
operator to start the test, exit the
vehicle and do a visual check and
determine that all exterior lighting is
functioning properly.
The following exterior lights are
cycled through the check:
• Parking
• Hazard
• Turn signals (left and right)
• High/Low beam headlights
• Brake
• Fog/Driving (Optional)
To start the test, from the Pre-Trip
Assistant main screen, select
Activate Exterior Light Inspection
Test.
Press Enter.
Once the test is started all exterior
lights ash on and off so that you
can perform a visual check. The test
continues to run until the
Applications button on the steering
wheel controls is pressed. The test
turns off if the vehicle is moving
faster than 5 km/h (3 mph).
