Check the fluid level on the dipstick. If
necessary, add automatic transmission
fluid DEXRON II or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (40 C—80 C or 104 F—175 F). You
may also check the level when the fluid
is cold (about room temperature,
0 C—40 C or 32 F—104 F) if the engine
has not been run for about five hours.
a. Clean all dirt from outside of the reser- voir tank.
b. Remove the reservoir cap by turning it counterclockwise and wipe the dipstick
clean. c. Reinstall the reservoir cap
d. Remove the reservoir cap again and look at the fluid level. If the fluid is
cold, the level should be in the “COLD”
range on the dipstick. Similarly, if it is
hot, the fluid level should be in the
“HOT” range. If the level is at the low
side of either range, add automatic
transmission fluid DEXRON II or III to
bring the level within the range.
e. After replacing the reservoir cap, visu- ally check the steering box case, vane
pump and hose connections for leaks
or damage.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steer-
ing could be damaged.
Keep your tire pressures at the proper
level.
The recommended cold tire pressures, tire
size and the cargo weight rating are given
in Section 8. Tire size and pressure are
also on the tire pressure label as shown.
You should check the tire pressures every
two weeks, or at least once a month. And
do not forget the spare!
Incorrect tire pressure may waste fuel,
reduce the comfort of driving, reduce tire
life and make your vehicle less safe to
drive.
If a tire frequently needs ref illing, have it
checked by your Toyota dealer.
