■Matching trailer ball height to
trailer coupler height
No matter which class of tow hitch
applies, for a more safe trailer
hookup, the trailer ball setup must
be the proper height for the coupler
on the trailer.
Coupler
Trailer ball
■Before towing
Check that the following conditions
are met:
●Ensure that your vehicle’s tires
are properly inflated. ( P.434)
●Trailer tires are inflated according
to the trailer manufacturer’s rec-
ommendation.
●All trailer lights work as required
by law.
●All lights work each time you con-
nect them.
●The trailer ball is set at the proper
height for the coupler on the
trailer.
●The trailer is level when it is
hitched.
Do not drive if th e trailer is not
level, and check for improper
tongue weight, overloading, worn
suspension, or other possible
causes.
●The trailer cargo is securely
loaded.
●The rear view mirr ors conform to
all applicable fede ral, state/provin-
cial or local regulations. If they do
not, install rear view mirrors
appropriate for towing purposes.
■Break-in schedule
If your vehicle is new or equipped
with any new power train compo-
nents (such as an engine, transaxle,
transfer [AWD models], rear differ-
ential [AWD models] or wheel bear-
ing), Toyota recommends that you
do not tow a trailer until the vehicle
has been driven for over 500 miles
(800 km).
After the vehicle has been driven for
over 500 miles (800 km), you can
start towing. However, for the next
500 miles (800 km), drive the vehi-
cle at a speed of less than 50 mph
(80 km/h) when towing a trailer, and
avoid full throttle acceleration.
■Maintenance
●If you tow a trailer, your vehicle
will require more fr equent mainte-
nance due to the additional load.
(See “Scheduled Maintenance
Guide” or “Owner ’s Manual Sup-
plement”.)
●Retighten the fixing bolts of the
towing ball and bracket after
approximately 600 miles (1000
km) of tra iler towing.
Toyota warranties do not
apply to damage or mal-
function caused by towing a
trailer for commercial pur-
poses.
Contact your Toyota dealer
for further information
about additional require-
ments such as a towing kit,
etc.

Driving
NOTICE
■To prevent water damage
Take all necessary safety mea-
sures to ensure that water dam-
age to the engine or other
components does not occur.
●Water entering the engine air
intake will cause severe engine
damage.
●Water entering the continuously
variable transmission will cause
deterioration in shift quality,
locking up of your transmission
accompanied by vibration, and
ultimately damage.
●Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the differen-
tials, continuously variable
transmission and transfer (AWD
models) case, reducing the gear
oil’s lubricating qualities.
■When you drive through
water
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the riverbed for
firmness. Drive slowly and avoid
deep water.
■Inspection after off-road driv-
ing
●Sand and mud that has accu-
mulated around brake discs
may affect braking efficiency
and may damage brake system
components.
●Always perform a maintenance
inspection aft er each day of
off-road driving that has taken
you through rough terrain, sand,
mud, or water. For scheduled
maintenance information, refer
to the “Scheduled Maintenance
Guide” or “Owner’s Manual
Supplement”.

■Repair and replacement
It is recommended that genuine
Toyota parts be used for repairs to
ensure performanc e of each sys-
tem. If non-Toyota parts are used in
replacement or if a repair shop other
than a Toyota dealer performs
repairs, confirm the warranty cover-
age.
■Allow inspection and repairs to
be performed by a Toyota
dealer
●Toyota technicians are
well-trained specialists and are
kept up to date with the latest ser-
vice information. They are well
informed about the operation of all
systems on your vehicle.
●Keep a copy of the repair order. It
proves that the maintenance that
has been performed is under war-
ranty coverage. If any problem
should arise while your vehicle is
under warranty, your Toyota
dealer will promptly take care of it.
General maintenance should be
performed on a daily basis. This
can be done by yourself or by a
Toyota dealer.
Scheduled maintenance should
be performed at specified inter-
vals according to the mainte-
nance schedule.
For details about maintenance
items and schedules, refer to the
“Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.
Maintenance require-
ments
To ensure safe and econom-
ical driving, day-to-day care

constituents, and a wide variety
of automobile components con-
tain or emit chemicals known to
the State of California to cause
cancer and birth defects and
other reproductive harm. Work
in a well ventilated area.
●Oils, fuels and fluids contained
in vehicles as well as waste pro-
duced by component wear con-
tain or emit chemicals known to
the State of California to cause

The OBD system determines
that a problem exists some-
where in the emission control
system. Your vehicle may not
pass the I/M test and may need
to be repaired. Contact your
Toyota dealer to service the
vehicle.

nected or discharged
Readiness codes that are set
during ordinary driving are erased.
Also, depending on your driving
habits, the readiness codes may
not be completely set.

• Is the tire infla-
tion pressure
correct?
• The tires should not be damaged
or excessively
worn.
• Have the tires been rotated
according to the
maintenance
schedule?
• The wheel nuts should not be
loose.

Maintenance and care
Check if the treadwear indica-
tors are showing on the tires.
Also check the tires for uneven
wear, such as excessive wear
on one side of the tread.
Check the spare tire condition
and pressure if not rotated.New tread
Worn tread
Treadwear indicator
The location of treadwear indicators
is shown by a “TWI” or “ ” mark, etc., molded into the sidewall of
each tire.
Replace the tires if the treadwear
indicators are s
howing 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 internal damage
●A tire goes flat repeatedly or can-
not be properly repaired due to the
size or location of a cut or other
damage
If you are not sure, consult with your
Toyota dealer.
■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.
■Maximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2
of the Gross Axle Weight Ratings
(GAWR) of either the front axle or
the rear axle, whi chever is greater.
For the GAWR, see the Certification
Label.
For the maximum load of the tire,
see the load limit at maximum cold
tire inflation pressure mentioned on
the sidewall of the tire. ( P.438)
