Driving
●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 the 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 mirrors conform to
all applicable federal, 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 trailer towing.
■If trailer sway occurs
One or more factors (crosswinds,
passing vehicles, rough roads, etc.)
can adversely affect handling of
your vehicle and trailer, causing
instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway-
ing by turning the steering wheel.
• Begin releasing the accelerator pedal immediately but very gradu-
ally to reduce speed.
Do not increase speed. Do not
apply vehicle brakes.
If you make no extreme correction
with the steering or brakes, your
vehicle and trailer should stabilize.
(if enabled, Trailer Sway Control can
also help to stabilize the vehicle and
trailer.)
●After the trailer swaying has
stopped:
• Stop in a safe pl ace. Get all occu-
pants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not
shifted.
Make sure the tongue weight is
appropriate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not over-
loaded after occupants get in.
If you cannot find any problems, the
speed at which trailer swaying
occurred is beyond the limit of your
particular vehicle-trailer combina-
tion. Drive at a lower speed to pre-
vent instability. Remember that
swaying of the towing vehicle-trailer
increases as speed increases.

HIGHLANDER_U
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 automatic
transmission will cause deterio-
ration in shift quality, locking up
of your transm ission accompa-
nied by vibration, and ultimately
damage.
●Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the differen-
tial, transmission and transfer
case, reducing t he 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 in brake drums and
around brake discs may affect
braking efficiency and may
damage brake system compo-
nents.
●Always perform a maintenance
inspection after each day of
off-road driving that has taken
you through rough terrain, sand,
mud, or water. For scheduled
maintenance info rmation, refer
to the “Warranty and Services
Guide”.

■Repair and replacement
It is recommended that genuine
Toyota parts be used for repairs to
ensure performance 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
and regular maintenance
are essential. It is the
owner’s responsibility to
perform regular checks.
Toyota recommends the fol-
lowing maintenance:
WARNING
■If your vehicle is not properly
maintained
Improper maintenance could
result in serious damage to the
vehicle and possible death or seri-
ous injury.
■Handling of the battery
●Engine exhaust, some of its
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
cancer and birth defects or
other reproductive harm. Avoid
exposure and wash any
affected area immediately.
●Battery posts, terminals and
related accessories contain lead
and lead compounds which are
known to cause brain damage.
Wash your hands after han-
dling. ( P.408)

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.
■Proper storage of the spare tire
As an improperly stored spare tire
may cause damage to the wire
cable that holds it, check that the
spare tire is stored properly on a
daily basis.
●If the stored spare tire appears to
be slanted or rattles while driving,
the spare tire may not be properly
stored. Store the spare tire again
by performing the following tire
change procedure correctly:
