Lane Departure Warning (LDW)
Light
For vehicles with the lane
departure warning system,
this light briefly comes
on amber, while starting
the vehicle, to indicate
that it is working.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
When driving at speeds of 35 mph (56 km) or greater
and LDW is turned on, a green warning symbol appears
when the system has detected lane markings on at
least one side of the vehicle.
For more information see Lane Departure Warning
(LDW) on page 2-49.
When LDW is active, the amber warning symbol comes
on and flashes. Three beeps sound if a lane marking
is crossed without using the turn signal. If the warning
symbol is not on, LDW is not operating and will not
warn when the vehicle crosses a lane marking.
Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light comes on when
the engine is very hot.
This light also comes on briefly when the vehicle is
started.
If the light does not go out or comes on and stays on
while driving, there may be a problem with the cooling
system. Driving with engine coolant temperature light
on could cause the vehicle to overheat, see Overheated
Engine Protection Operating Mode on page 5-30.
See Engine Overheating on page 5-28 and DIC Warnings
and Messages on page 3-73 for more information.
