the vehicle’s windows. Glass tinting interferes
with the system’s ability to receive GPS signals and
causes the system to malfunction. The window
might have to be replaced to correct the problem.
This would not be covered by the warranty.
For more information if the GPS is not functioning
properly, seeIf the System Needs Service on page 4-58
andProblems with Route Guidance on page 4-58.

wear your safety belt — SeeSafety Belts: They Are for
Everyone on page 1-28.
{CAUTION:
Assume that other road users (pedestrians,
bicyclists, and other drivers) are going to be
careless and make mistakes. Anticipate what
they might do and be ready. In addition:
Allow enough following distance between
you and the driver in front of you.
Focus on the task of driving.
Driver distraction can cause collisions resulting in
injury or possible death. These simple defensive
driving techniques could save your life.
