Power steering fluid
■Fluid level
The fluid level should be within the appropriate range.
Full (when hot)
Add fluid (when hot)
Full (when cold)
Add fluid (when cold)
Hot: The vehicles has been driven around 50 mph (80 km/h) for 20
minutes, or slightly longer in frigid temperatures. (Fluid tem-
perature, 140 F - 175 F [60 C - 80 C]).
Cold: The engine has not been run for about 5 hours. (Room tem-
perature, 50 F - 85 F [10 C - 30 C]).
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

AVALON_U (OM41428U)■Checking the fluid level
Make sure to check the fluid type and prepare the necessary items.
Clean all dirt off the reservoir.
Remove the cap by turning it counterclockwise.
Wipe the dipstick clean.
Reinstall and remove the reservoir cap again.
Check the fluid level.
Fluid typeAutomatic transmission fluid DEXRON® II or III
ItemsRag or paper, clean funnel (only for adding fluid)
CAUTION
■When checking the reservoir
Take care, as the reservoir may be hot.
NOTICE
■When adding fluid
Avoid overfilling, or the power steering may be damaged.
■After replacing the reservoir cap
Check the steering box case, vane pump and hose connections for leaks or
damage.

When trouble arises

AVALON_U (OM41428U)
CAUTION
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If the tire is flat, change to the spare tire and have the flat tire repaired
by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pressure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
