Vehicle specifications
HIGHLANDER HV_U
Outside temperature
SAE 0W-16 is the best choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-16 is not available,
SAE 0W-20 oil may be used.
However, it must be replaced
with SAE 0W-16 at the next oil
change.
Oil viscosity (0W-16 is explained
here as an example):
• The 0W in 0W-16 indicates the characteristic of the oil
which allows cold startability.
Oils with a lower value before the W allow for easier starting
of the engine in cold weather.
• The 16 in 0W-16 indicates the viscosity characteristic of the
oil when the oil is at high tem-
perature. An oil with a higher
viscosity (one with a higher
value) may be better suited if
the vehicle is operated at high
speeds, or under extreme
load conditions.
How to read oil container label:
API registered mark is added to
some oil containers to help you
select the oil you should use.

5248-1. Specifications
HIGHLANDER HV_UGrade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel
than the minimum
required by law. Warning: The temperature grades
of a tire assume tha
t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
Glossary of tire terminology
Tire related termMeaning
Cold tire infl ation pressure
Tire pressure when the vehicle has been
parked for three hours or more, or has not
been driven more than 1 mile or 1.5 km
under that condition
Maximum inflation pressure
The maximum cold inf lated pressure to
which a tire may be inflated, shown on the
sidewall of the tire
Recommended inflation pres-
sureCold tire inflation pressure recommended
by a manufacturer
Accessory weight
The combined weight (in excess of those
standard items which may be replaced) of
hybrid transmission, power steering,
power brakes, power windows, power
seats, radio and heater, to the extent that
these items are available as fac-
tory-installed equipment (whether installed
or not)
Curb weight
The weight of a motor vehicle with stan-
dard equipment, including the maximum
capacity of fuel, oil and coolant, and if so
equipped, air conditioning and additional
weight optional engine
