Vehicle−To−Vehicle Distance Control Mode Failure Warning; E1; E2 - Toyota sienna 2004 Service Manual

VEHICLE−TO−VEHICLE DISTANCE
CONTROL MODE FAILURE WARNING
If there is trouble somewhere in the dy-
namic laser cruise control while the ve-
hicle−to−vehicle distance control mode is
on, the master warning light comes on
and the alarm sounds, and one of the
warning codes "E1", "E2" or "E3" will ap-
pear on the display. Dynamic laser cruise
control is automatically cancelled.
If "E3" appears on the display,
"CRUISE" indicator light in the instrument
cluster also flashes.

If "E1" appears on the display, the sys-
tem cannot easily measure the vehicle−to−
vehicle distance because of a dirty laser
radar sensor glass while the dynamic la-
ser cruise control is on.
If this code appears, clean the sensor
glass with a soft cloth and try setting the
preset speed again. If the dirt is removed
without cleaning, the system will automati-
cally enter the ready mode.
If the system does not enter the ready
mode even after cleaning or the code re-
mains on the display, the system might be
malfunctioning. Although there is no prob-
lem to continue driving, please contact
your Toyota dealer.
CAUTION
Always keep the sensor glass and
never allow it to be covered with
icicle or any substance, so it can de-
tect the vehicle in front.

I n f o r ma t i o n P r o v i d e d b y :
If "E2" appears on the display, the sys-
tem cannot easily measure the vehicle−to−
vehicle distance because of the following
conditions:
D
The wipers are operating at high or low
speeds
D
Direct sunlight from the front
D
It is difficult to make a measurement
because of bad weather (such as rainy,
foggy, or snowy weather)
In the following cases, dynamic
cruise control switches to the ready mode:
D
The wipers are stopped or
switched to intermittent operation.
D
No direct sunlight from the front
In the above conditions, push the lever up
in the "+ RES" direction and release it.
Dynamic laser cruise control will be re-
stored. If the setting operation cannot be
performed or if the warning code still ap-
pears even after the weather clears, the
system might have malfunctioned.
though there is no problem to continue
driving, please contact your Toyota dealer.
