refilled in between oil maintenance inter- vals.
●When the engine is new, for example directly after purchasing the vehicle or after replacing the engine
●If low quality oil or oil of an inappropri-ate viscosity is used
●When driving at high engine speeds or with a heavy load, when towing
(vehicles with towing packages), or when driving while accelerating or decelerating frequently
●When leaving the engine idling for a long time, or when driving frequently
through heavy trafficThe coolant level is satisfactory if it
is between the “MAX” and “MIN”
lines on the reservoir when the
engine is cold.
Reservoir cap

molded into the sidewall of each tire.
Replace the tires if the treadwear indi-
cators are showing on a tire.
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating inter- nal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or location of a cut or other damage
If you are not sure, consult with any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if
it has seldom or never been used, or damage is not obvious.
■Low profile tires
Generally, low profile tires will wear
more rapidly and tire grip performance will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires on snowy and/or icy roads and drive carefully at a speed appropriate for road and weather
conditions.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow
tires is lost.
■Checking the tire valves
When replacing the tires, check the tire
valves for deformation, cracks, and other damage.
WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.Failure to do so may cause damage
to parts of the drive train as well as dangerous handling characteristics, which may lead to an accident result-
ing in death or serious injury.
●Do not mix tires of different makes,
models or tread patterns. Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and
snow tires.
●Do not use tires that have been
used on another vehicle. Do not use tires if you do not know how they were used previously.
NOTICE
■Low profile tires
Low profile tires may cause greater damage than usual to the tire wheel when sustaining impact from the road
surface. Therefore, pay attention to the following:
●Be sure to use proper tire inflation pressure. If tires are under-inflated, they may be damaged more
severely.
●Avoid potholes, uneven pavement,
curbs and other road hazards. Fail- ure to do so may lead to severe tire and wheel damage.
