Adjustment procedureWARNING
■When adjusting the seat posi-
tion
●Take care when adjusting the
seat position to ensure that
other passengers are not
injured by the moving seat.
●Do not put your hands under the
seat or near the moving parts to
avoid injury.
Fingers or hands may become
jammed in the seat mechanism.
●Make sure to leave enough
space around the feet so they
do not get stuck.
■Seat adjustment
To reduce the risk of sliding under
the lap belt during a collision, do
not recline the se at more than
necessary.
If the seat is too reclined, the lap
belt may slide past the hips and
apply restraint for ces directly to
the abdomen, or your neck may
contact the shoulder belt, increas-
ing the risk of death or serious
injury in the event of an accident.
Adjustments should not be made
while driving as the seat may
unexpectedly move and cause
the driver to lose control of the
vehicle.

Owners Manual_USA_M0C052_enbecause visibility will be reduced,
the windows may become fogged-
up, and the
road will be slippery.
●Drive carefully whe n it starts to
rain, because the road surface will
be especially slippery.
●Refrain from high speeds when
driving on an expressway in the
rain, because there may be a
layer of water between the tires
and the road surface, preventing
the steering and brakes from
operating properly.
■Engine speed while driving
In the following conditions, the
engine speed may become high
while driving.
This is due to automatic up-shifting
control or down-shifting implementa-
tion to meet driving conditions. It
does not indicate sudden accelera-
tion.
●The vehicle is judged to be driving
uphill or downhill
●When the accelerator pedal is
released
●When the brake pedal is
depressed while “TOW HAUL”
mode or “TOW+” mode is selected
■Restraining the hybrid system
output (Brake Override System)
●When the accelerator and brake
pedals are depressed at the same
time, the hybrid system output
may be restrained.
●A warning messag e is displayed
on the multi-information display

■When driving the vehicle
●Do not drive if you are unfamil-
iar with the location of the brake
and accelerator pedals to avoid
depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the
brake pedal will result in sudden
acceleration that may lead to an
accident.
• When backing up, you may twist your body around, leading to dif-
ficulty in operating the pedals.
Make sure to operate the pedals
properly.
• Make sure to keep a correct driving posture even when mov-
ing the vehicle only slightly. This
allows you to depress the brake
and accelerator pedals properly.

Your vehicle will handle differ-
ently when towing a trailer. To
help avoid an accident, death or
serious injury, keep the following
in mind when towing:
 Speed limits for towing a
trailer vary by state or prov-
ince. Do not exceed the
posted towing speed limit.
 Toyota recommends that the
vehicle-trailer speed limit is 65
mph (104 km/h) on a flat,
straight, dry road. Do not
exceed this limit, the posted
towing speed limit or the
speed limit for your trailer as
set forth in your trailer owner’s
manual, whichever is lowest.

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
