Your vehicle will handle differently
when towing a trailer. In order to
avoid accident, d eath or serious
injury, keep the following in mind
when towing:
■Checking connections
between trailer and lights
Stop the vehicle and check the
operation of the connection
between the trailer and lights after
driving for a brief period as well as
before starting off.
■Practicing driving with a cou -
pled trailer
 Get the feel for turning, stopping
and reversing with the trailer
coupled by practicing in an area
with no or light traffic.
 When reversing with a coupled
trailer, hold the section of the
steering wheel nearest to you
and rotate clockwise to turn the
trailer left or co unterclockwise to
turn it right. Always rotate a little
at a time to prevent steering
error. Have someone guide you
when reversing to lessen the risk
of an accident.
■Increasing vehicle-to-vehicle
distance
At a speed of 10 km/h (6 mph), the
distance to the vehicle running
ahead of you should be equivalent
to or greater th an the combined
length of you r vehicle and trailer.
Avoid sudden braking that may
cause skidding. Otherwise, the
vehicle may spin out of control. This
is especially true when driving on
wet or slippery road surfaces.

NOTICE
■When the rear bumper strength -
ening material is aluminum
Ensure the steel bracket part does not
come directly in contact with that
area.
When steel and aluminum come into
contact, there is a reaction similar to
corrosion, which will weaken the sec - tion concerned and may result in
damage. Apply a rust inhibitor to parts
that will come in contact when attach - ing a steel bracket.

5-1. Before driving
Driving
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. D ecelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the tr ailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor -
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre -
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut -
ing lane changes.
■Transmission information
To maintain engine braking effi -
ciency, when using engine braking,
do not use the transmission in D.
( →P.321)
■If the hybrid system overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the hybrid system overheating. If
the high coolant temperature warn -
ing light indicates that the hybrid
system is overheating, turn the air
conditioning off immediately, leave
the road and stop the vehicle in a
safe place. ( →P.611)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift lever to P.
■Break-in schedule
Toyota recommends that vehicles fitted
with new power train components
should not be used for towing trailers for the first 800 km (500 miles).
■Maintenance
●Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight bur -
den placed on the vehicle compared to normal driving.
●Retighten all bolts securing the hitch - ing ball and bracket after towing for
approximately 1000 km (600 miles).
■If trailer sway occurs
One or more factor s (crosswinds, pass- ing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle
and trailer, causing instability.

3805-5. Using the driving support systems
When a vehicle is de tected running ahead of you, the system automatically deceler-
ates your vehicle. When a great er reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this time). The system will
respond to changes in the speed of the vehicle ahead in order to maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning war ns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also sto p (vehicle is stopped
by system control). After the veh icle ahead starts off, pressing the “+RES” switch or
depressing the accelerator pedal (start-off operation) will res ume follow-up cruising.
If the start-off operation is not performed, system control continues to keep your
vehicle stopped.
When the turn signal lever is operated and your vehicle moves t o an overtaking lane
while driving at 50 mph (80 km/h) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identificat ion of what is an overtaking lane may be determined solely
based on the location of the ste ering wheel in the vehicle (left side driver position
versus right side driv er position.) If the vehicle is driven to a region where the over-
taking lane is on a different sid e from where the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e opposite direction to
the overtaking lane (e.g., if th e driver normally operates the vehicle in a region
where the overtaking lane is to t he right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
Example of acceleration
When there are no longer any preceding vehicles driving slower than the
set speed
The system accelerates until the set speed is reached. The system then returns to
constant speed cruising.
