■
When the front-wheel drive control switch is shifted to “4L”
VSC is automatically turned off.
■
If the “4HI” indicator flashes
The transfer mode may not successfully change. Drive straight ahead while
accelerating or decelerating, or drive in reverse.
■
If the “4LO” indicator continues to flash
The transfer mode may not successfully change. Operate the front-wheel
drive control switch again.
■
If the “4LO” indicator continues to flash and a buzzer sounds
The shift lever is not in N and/or the vehicle is moving. Stop the vehicle com-
pletely, shift the shift lever to N and make sure that the indicator stops flash-
ing.
■
If the “4HI” or “4LO” indicator flashes rapidly
There may be a malfunction in the four-wheel drive system. Have the vehicle
inspected by your Toyota dealer immediately.
■
Four-wheel drive usage frequency
You should drive in four-wheel drive for at least 10 miles (16 km) each month.
This will assure that the front drive components are lubricated.
CAUTION
■
Shifting the front-wheel drive control switch from “2WD” to “4H” while
driving
Never operate the front-wheel drive control switch if the wheels are slipping.
Stop the slipping or spinning before shifting.
■
When the vehicle is parked
If the shift lever is moved before the “4LO” indicator turns on/off, the transfer
mode may not be shifted completely. The transfer mode disengages both
the front and rear driveshafts from the powertrain and allows the vehicle to
move regardless of the shift position. (At this time, the indicator blinks and
the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode before placing transmission in P.
