If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road conditions. If the light comes on,
replace it as soon as possible.
The system must be reset after the en-
gine oil replacement. Reset the system by
the following procedure:1. Turn the engine switch to the “ACC” or “LOCK” position with the odometer
reading shown. (For details, see
“Odometer and two trip meters” on
page 190 in this Section.)
2. Turn the engine switch to the “ON” position while holding down the trip
meter reset button.
Hold down the button for at least 5 sec-
onds. The odometer indicates “000000”
and the light goes off.
If the system fails to reset, the light will
continue flashing. (o) Third Seats Warning Light and

Vehicles with cruise control or dynamic
laser cruise control—When the cruise con-
trol is being used, even if you downshift
from “D” to “4”, engine braking will not be
enabled because the cruise control is not
cancelled.
For ways to decrease the vehicle speed,
see “Cruise control” on page 222 or “Dy-
namic laser cruise control” on page 225
in this Section.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to skid or
spin.
(d) Using “3”, “2” and “L” positions
The “3”, “2” and “L” positions are used for
strong engine braking as described pre-
viously.
With the selector lever in “3”, “2” or “L”,
you can start the vehicle in motion as
with the lever in “D”.
With the selector lever in “3” or “2”, the
vehicle will start in first gear and automat-
ically shift to third gear or second gear.With the selector lever in “L”, the trans-
mission is engaged in first gear.
NOTICE

Be careful not to overrev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given below for your reference:
Twowheel drive models “3” 162 km/h (100 mph) . . . . . . . .
“2” 104 km/h (64 mph) . . . . . . . .
“L” 58 km/h (36 mph) . . . . . . . . .
Allwheel drive models “3” 154 km/h (95 mph) . . . . . . . . .
“2” 99 km/h (61 mph) . . . . . . . . . .
“L” 55 km/h (34 mph) . . . . . . . . . .
 Do not continue hill climbing or
hard towing for a long time in the
“3”, “2” or “L” position. This may
cause severe automatic transmis-
sion damage from overheating. To
prevent such damage, “4” position
should be used in hill climbing or
hard towing.
