■Adjusting the mirror angle
when the vehicle is revers-
ing
With the shift lever in R, adjust
the mirror angle at a desired
position. The adjusted angle will
be memorized and the mirror
will automatically tilt to the mem-
orized angle whenever the shift
lever is shifted to R from next
time.
The memorized downward tilt
position of the mirror is linked to
the normal position (angle
adjusted with the shift lever in
other than R). Therefore, if the
normal position is changed after
adjustment, the tilt position will
also change.
When the normal position is
changed, readjust the angle in
reversing.

Driving
WARNING
●Do not adjust the position of the
steering wheel, the seat, or the
inside or outside rear view mir-
rors while driving.
Doing so may result in a loss of
vehicle control.
●Always check that all passen-
gers’ arms, head or other parts
of their body are not outside the
vehicle.
●AWD models: Do not drive the
vehicle off-road. This is not an
AWD vehicle designed for off-
road driving. Proceed with all
due caution if it becomes
unavoidable to drive off-road.
●AWD models: Do not drive
across a river or through other
bodies of water. This may cause
electric/electronic components
to short circuit, damage the
engine or cause other serious
damage to the vehicle.
●Do not drive in excess of the
speed limit. Even if the legal
speed limit permits it, do not
drive over 85 mph (140 km/h)
unless your vehicle has high-
speed capability tires. Driving
over 85 mph (140 km/h) may
result in tire failure, loss of con-
trol and possible injury. Be sure
to consult a tire dealer to deter-
mine whether the tires on your
vehicle are high-speed capabil-
ity tires or not b efore driving at
such speeds.
■When driving on slippery
road surfaces
●Sudden braking, acceleration
and steering may cause tire
slippage and reduce your ability
to control the vehicle.
●Sudden acceleration, engine
braking due to shifting, or
changes in engine speed could
cause the vehicle to skid.
●After driving through a puddle,
lightly depress the brake pedal
to make sure that the brakes
are functioning properly. Wet
brake pads may prevent the
brakes from functioning prop-
erly. If the brakes on only one
side are wet and not functioning
properly, steering control may
be affected.
■When shifting the shift lever
●Do not let the vehicle roll back-
ward while a fo rward driving
position is selected, or roll for-
ward while the shift lever is in R.
Doing so may result in an acci-
dent or damage to the vehicle.
●Do not shift the shift lever to P
while the vehicle is moving.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the sh ift lever to R
while the vehicle is moving for-
ward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the shift lever to a
driving position while the vehicle
is moving backward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Moving the shift lever to N while
the vehicle is moving will disen-
gage the hybrid system. Engine
braking is not a vailable with the
hybrid system disengaged.

NOTICE
■Avoiding damage to vehicle
parts
●Do not turn the steering wheel
fully in either direction and hold
it there for an extended period
of time.
Doing so may damage the
power steering motor.
●When driving over bumps in the
road, drive as slowly as possible
to avoid damaging the wheels,
underside of the vehicle, etc.
■If you get a flat tire while driv-
ing
A flat or damaged tire may cause
the following situations.
●It may be difficult to control your
vehicle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnor-
mally.
Hold the steering wheel firmly and
gradually depress the brake pedal
to slow down the vehicle.
Information on what to do in case
of a flat tire ( P.491)
■When encountering flooded
roads
Do not drive on a road that has
flooded after heavy rain, etc.
Doing so may cause the following
serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by
water immersion
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have your
Toyota dealer c heck the following:
●Brake function
●Changes in quantity and quality
of oil and fluid used for the
engine, hybrid transmission
(front and rear), etc.
●Lubricant condition for the bear-
ings and suspension joints
(where possible), and the func-
tion of all joints, bearings, etc.
■When parking the vehicle
Always set the parking brake, and
shift the shift lever to P. Failure to
do so may cause the vehicle to
move or the vehicle may acceler-
ate suddenly if t he accelerator
pedal is accidentally depressed.

Driving
incorrect installation may cause
damage to the vehicle’s lights.
Please take care to comply with
your state’s laws when installing
trailer lights.
Your vehicle will handle differ-
ently when towing a trailer. Help
to avoid an accident, death or
serious injury, keep the follow-
ing 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.
Instability of the towing vehi-
cle-trailer combination (trailer
sway) increases as speed
increases. Exceeding speed
limits may cause loss of con-
trol. 
Before starting out, check the
trailer lights, tires and the
vehicle-trailer connections.
Recheck after driving a short
distance.
 Practice turning, stopping and
reversing with the trailer
attached in an area away
from traffic until you become
accustomed to the feel of the
vehicle-trailer combination.
 Reversing with a trailer
attached is difficult and
requires practice. Grip the
bottom of the steering wheel
and move your hand to the
left to move the trailer to the
left. Move your hand to the
right to move the trailer to the
right. (This is generally oppo-
site to reversing without a
trailer attached.) Avoid sharp
or prolonged turning. Have
someone guide you when
reversing to reduce the risk of
an accident.
 As stopping distance is
increased when towing a
trailer, vehicle-to vehicle dis-
tance should be increased.
For each 10 mph (16 km/h) of
speed, allow at least one
vehicle and trailer length.
 Avoid sudden braking as you
may skid, resulting in the
trailer jackknifing and a loss of
vehicle control. This is espe-
cially true on wet or slippery
surfaces.
NOTICE
■Do not directly splice trailer
lights
Do not directly splice trailer lights.
Directly splicing trailer lights may
damage your vehicle’s electrical
system and cause a malfunction.
Trailer towing tips

2284-1. Before driving
Avoid jerky starts or sudden
acceleration.
 Avoid jerky steering and
sharp turns, and slow down
before making turn.
 Note that when making a turn,
the trailer wheels will be
closer than the vehicle wheels
to the inside of the turn. Com-
pensate by making a wider
than normal turning radius.
 Slow down before making a
turn, in cross winds, on wet or
slippery surfaces, etc.
Increasing vehicle speed can
destabilize the trailer.
Take care when passing other
vehicles. Passing requires
considerable distance. After
passing a vehicle, do not for-
get the length of your trailer,
and be sure you have plenty
of room before changing
lanes.
 To maintain engine braking
efficiency and charging sys-
tem performance, when using
engine braking, do not use
the transmission in D.
 Instability happens more fre-
quently when descending
steep or long downhill grades.
Before descending, slow
down and downshift. Do not
make sudden downshifts
while descending steep or
long downhill grades.
 Avoid holding the brake pedal down too long or applying the
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.511)
 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.

2294-1. Before driving

Driving
5Shift 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
depressed.
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.243)
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, differential or wheel bearing),
Toyota recommends that you do not
tow a trailer unt il 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 45 mph
(72 km/h) when towing a trailer, and
avoid full throttle acceleration.
■Maintenance
●If you tow a traile r, your vehicle
will require more f requent 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.
■If trailer sway occurs
One or more factors (crosswinds,
passing vehicles, rough roads, etc.)
can adversely affect handling of
your vehicle and t railer, causing
instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to contr ol 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 place. 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.

2324-2. Driving procedures
■When the ambient temperature
is low, such as during winter
driving conditions
When starting the hybrid system,
the flashing time of the “READY”
indicator may be long. Leave the
vehicle as it is u ntil the “READY”
indicator is steady on, as steady
means the vehicle is able to move.

■Stopping the hybrid system
in an emergency
●If you want to stop the hybrid
system in an emergency while
driving the vehicle, press and
hold the power switch for more
than 2 seconds, or press it
briefly 3 times or more in suc-
cession. ( P.459)
However, do not touch the
power switch while driving
except in an emergency. Turn-
ing the hybrid system off while
driving will not cause loss of
steering or braking control, how-
ever, power assist for the steer-
ing wheel may be lost making it
difficult to steer smoothly before
stopping the vehicle depending
on the remaining charge in the
12-volt battery or usage condi-
tions. In this situation, you
should pull over and stop the
vehicle as soon as it is safe to
do so.
●If the power switch is operated
while the vehicle is running, a
warning message will be shown
on the multi-information display
and a buzzer sounds.
●When restarting the hybrid sys-
tem after an emergency shut-
down, shift the shift lever to N
and press the power switch
shortly and firmly.
■When parking
Exhaust gases include harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating for
a long time. If such a situation
cannot be avoided, park the
vehicle in an open space and
ensure that exhaust fumes do
not enter the ve hicle interior.
●Do not leave the hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
the vehicle while the hybrid sys-
tem is operating, exhaust gases
may collect and enter the vehi-
cle.
