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

1944-1. Before driving
Owners Manual_USA_M0C031_enapproximately 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 swaying 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 ext reme 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.
Dinghy towing
Your vehicle is not designed
to be dinghy towed (with 4
wheels on the ground)
behind a motor home.
NOTICE
■To avoid serious damage to
your vehicle
Do not tow your vehicle with the
four wheels on the ground.

WARNING
■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 vehicle 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.

2004-2. Driving procedures
Owners Manual_USA_M0C031_en
*1: Shifting to the D position allows the system to select a gear suit-
able for the driving conditions.
Setting the shift lever to the D
position is recommended for nor-
mal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of
the possible gear ranges, con-
trols engine brak ing force, and
prevents unnecessary upshifting.
■Driving on a downhill
On declines, there may be case
where the vehicle shifts down auto-
matically to obtain engine braking.
As a result of the downshifting, the engine speed may increase.
■To protect the a
utomatic trans-
mission
●If the tires spin continually when
the vehicle becomes stuck in mud,
dirt or snow, or if the accelerator
pedal is depressed and released
repeatedly while driving, the auto-
matic transmission temperature
may become too high and the
automatic transmission may be
damaged.
To avoid damaging the automatic
transmission, the system may
temporarily lock the gear. If the
automatic transmission tempera-
ture falls, the gear locking is can-
celed and the automatic
transmission is returned to the
normal operation.
●If the automatic tr ansmission fluid
temperature is high, “Transmis-
sion Oil Temp. High Stop in a Safe
Place and See Owner’s Manual”
will be displayed on the multi-
information display. Immediately
stop the vehicle in a safe place,
shift the shift lever to P and wait
until the warning message go off.
If the warning message go off, you
may start the vehicle again. If the
warning message do not go off,
contact your Toyota dealer.
■When driving with dynamic
radar cruise control with full-
speed range (if equipped) or
cruise control activated (if
equipped)
Even when perform ing the following
actions with the intent of enabling
engine braking, engine braking will
not activate because dynamic radar
cruise control with full-speed range
or cruise control will not be can-
celed.
●While driving in S mode, down-
shifting to 9, 8, 7, 6, 5 or 4.
