Driving
brakes too frequently. This
could cause the brakes to
overheat and result in
reduced braking efficiency.
 Due to the added load of the
trailer, your vehicle’s hybrid
system may overheat on hot
days (at temperatures over
85°F [30°C]) when driving up
a long or steep grade. If the
engine coolant temperature
gauge indicates overheating,
immediately turn off the air
conditioning (if in use), pull
your vehicle off the road and
stop in a safe spot. ( P.535)
 Always place wheel blocks
under both the vehicle’s and
the trailer’s wheels when
parking. Apply the parking
brake firmly, and put the
transmission in P. Avoid park-
ing on a slope, but if unavoid-
able, do so only after
performing the following:
1 Apply the brakes and keep
them applied.
2 Have someone place wheel
blocks under both the vehi-
cle’s and trailer’s wheels.
3 When the wheel blocks are in
place, release the brakes
slowly until the blocks absorb
the load.
4 Apply the parking brake
firmly.
5 Shift into P and turn off the
hybrid system. 
When restarting after parking
on a slope:
1 With the transmission in P,
start the hybrid system. Be
sure to keep the brake pedal
pressed.
2 Shift into a forward gear. If
reversing, shift into R.
3 If the parking brake is in man-
ual mode, release the park-
ing brake. ( P.205)
4 Release the brake pedal, and
slowly pull or back away from
the wheel blocks. Stop and
apply the brakes.
5 Have someone retrieve the
blocks.
■Break-in schedule
If your vehicle is new or equipped
with any new power train compo-
nents (such as an engine, transmis-
sion, transfer [4WD models], rear
differential or wheel bearing), Toyota
recommends that y ou 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 “Owner’s Warranty Informa-
tion Booklet” or “Scheduled Main-
tenance Guide” / “Owner’s Manual
Supplement”.)
●Retighten the fixing bolts of the
towing ball and bracket after

NOTICE
■To prevent water damage
Take all necessary safety mea-
sures to ensure that water dam-
age to the engine, hybrid system
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 transmission 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-
tials, transmission and transfer
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 riv-
erbed for firmness. Drive slowly
and avoid deep water.
●When crossing a river or a pud-
dle, be sure to cross it without
stopping midway. If you stop or
drive at extremely low speeds in
water, water may enter the vehi-
cle and damage the hybrid bat-
tery making the vehicle unable
to be driven.
■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 after 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”.

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.
