Lane Departure Warning (LDW)
If the vehicle has the LDW system. Read this entire
section before using the system.
{
CAUTION:
The Lane Departure Warning (LDW) system does
not steer the vehicle and is only an aid to help you
stay in your driving lane. The LDW system may not:
•
Provide you with enough time to avoid a lane
change collision.
•
Be loud enough for you to hear the warning
beeps.
•
Work properly under bad weather conditions or
if the windshield is not kept clean.
•
Detect lane markings and will not detect road
edges.
•
Warn you that your vehicle is crossing a lane
marking if the system does not detect the lane
marking.
CAUTION: (Continued)
CAUTION: (Continued)
LDW will indicate the system is working whenever
it detects either the left or right lane marking. So if
you depart on the side of the lane that LDW is not
detecting, LDW will not warn you.
If you do not carefully maintain your vehicle position
within the lane, vehicle damage, injury, or death
could occur. Even with LDW, always keep your
attention on the road and maintain proper vehicle
position within the lane. Always keep the windshield
clean and do not use LDW in bad weather
conditions.
When the vehicle crosses a detected lane marking, the
LDW symbol will flash and you will hear three beeps.
LDW will not warn you if the turn signal is on or if
the vehicle makes a sharp maneuver. Before making
a lane change, check the vehicle’s mirrors, glance over
your shoulder for vehicles and hazards, and turn on
the turn signal before changing lanes.
