4-1. Before driving
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
zGet the feel for turning, stopping
and reversing with the trailer
coupled by practicing in an area
with no or light traffic.
zWhen reversing with a coupled
trailer, hold the section of the
steering wheel nearest to you
and rotate clockwise to turn the
trailer left or counterclockwise 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 than the combined
length of your 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.
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the trailer 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.

WARNING
■Toyota Safety Sense
The Toyota Safety Sense is designed to operate under the assumption that the driver will drive safely, and is
designed to help reduce the impact to the occupants and the vehicle in the case of a collision or assist the driver
in normal driving conditions. As there is a limit to the degree of rec-ognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The driver is always responsible for paying
attention to the vehicle’s surroundings and driving safely.
Sensors
WARNING
■To avoid malfunction of the radar sensor
Observe the following precautions.
Otherwise, the radar sensor may not operate properly, possibly leading to an accident resulting in death or seri-
ous injury.

steering, emergency steering assist
will assist the steering movements
to help enhance the vehicle stability
and for lane departure prevention.
■Intersection right/left turn
assistance
If the system determines that there
is a high possibility of a collision in
the following situations, it will assist
with a Pre-collision warning and, if
necessary Pre-collision braking.
Depending on the configuration of
the intersection, it may not be pos-
sible to support.
z When you turn right/left at an
intersection and cross the path of
an oncoming vehicle
z When you turn right/left, pedes-
trian is detected in the forward
direction and estimated to enter
your vehicle’s path (bicyclists are
not detected.)
WARNING
■Limitations of the pre-collision system
●The driver is solely responsible for safe driving. Always drive safely, taking care to observe your sur-
roundings. Do not use the pre-collision system instead of normal braking opera-
tions under any circumstances. This system will not prevent colli-sions or lessen collision damage or
injury in every situation. Do not overly rely on this system. Failure to do so may lead to an accident,
resulting in death or serious injury.
●Although this system is designed to
help avoid a collision or help reduce the impact of the collision, its effec-tiveness may change according to
various conditions, therefore the system may not always be able to achieve the same level of perfor-
mance. Read the following conditions care-fully. Do not overly rely on this sys-
tem and always drive carefully.
• Conditions under which the system
may operate even if there is no pos- sibility of a collision: →P. 1 9 9
• Conditions under which the system may not operate properly: →P. 2 0 1

4-5. Using the driving support systems
WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. The LTA system does not automatically drive the vehicle or reduce the amount of attention that
must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving
safely by paying careful attention to the surrounding conditions and operating the steering wheel to cor-
rect the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as from
driving for a long period of time.
●Failure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.
●When not using the LTA system, use the LTA switch to turn the sys-
tem off.
■Situations unsuitable for LTA
system
In the following situations, use the LTA switch to turn the system off. Fail-
ure to do so may lead to an accident, resulting in death or serious injury.
●Vehicle is driven on a road surface which is slippery due to rainy weather, fallen snow, freezing, etc.
●Vehicle is driven on a snow-cov-ered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust,
etc.
●Vehicle is driven in a temporary
lane or restricted lane due to con- struction work.
●Vehicle is driven in a construction zone.
●A spare tire, tire chains, etc., are equipped.
●When the tires have been exces-sively worn, or when the tire infla-tion pressure is low.
●When tires of a size other than specified are installed.
●Vehicle is driven in traffic lanes other than that highways and free-
ways.
●When your vehicle is towing a
trailer or during emergency towing
■Preventing LTA system malfunc-
tions and operations performed by mistake
●Do not modify the headlights or
place stickers, etc., on the surface of the lights.
●Do not modify the suspension, etc. If the suspension, etc., needs to be replaced, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do not install or place anything on the hood or grille. Also, do not install a grille guard (bull bars, kan-
garoo bar, etc.).
●If your windshield needs repairs,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Conditions in which functions may not operate properly
In the following situations, the func- tions may not operate properly and the vehicle may depart from its lane.
Drive safely by always paying careful attention to your surroundings and operate the steering wheel to correct
the path of the vehicle without relying solely on the functions.

WARNING
■Before using dynamic radar cruise control
●Driving safely is the sole responsi-bility of the driver. Do not rely solely on the system, and drive safely by
always paying careful attention to your surroundings.
●The dynamic radar cruise control provides driving assistance to
reduce the driver’s burden. How- ever, there are limitations to the assistance provided.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be cor- rectly detecting the vehicle ahead: → P. 2 2 2
• Conditions under which the vehicle- to-vehicle distance control mode may not function correctly: →P. 2 2 3
●Set the speed appropriately depending on the speed limit, traffic flow, road conditions, weather con-
ditions, etc. The driver is responsi- ble for checking the set speed.
●Even when the system is function-ing normally, the condition of the preceding vehicle as detected by
the system may differ from the con- dition observed by the driver. Therefore, the driver must always
remain alert, assess the danger of each situation and drive safely. Relying solely on this system or
assuming the system ensures safety while driving can lead to an accident, resulting in death or seri-
ous injury.
●Switch the dynamic radar cruise
control setting to off, using the cruise control main switch when not in use.
■Cautions regarding the driving assist systems
Observe the following precautions, as there are limitations to the assistance provided by the system. Failure to do
so may cause an accident resulting in death or serious injury.
●Assisting the driver to measure fol-lowing distance
The dynamic radar cruise control is
only intended to help the driver in
determining the following distance
between the driver’s own vehicle and
a designated vehicle traveling ahead.
It is not a mechanism that allows
careless or inattentive driving, and it
is not a system that can assist the
driver in low-visibility conditions.
It is still necessary for driver to pay
close attention to the vehicle’s sur-
roundings.

4-5. Using the driving support systems
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may become
shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater 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 warns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the turn signal lever is operated and your vehicle moves to an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left side driver position

Driving
Select a distance from the table
below. Note that the distances
shown correspond to a vehicle
speed of 80 km/h (50 mph). Vehi-
cle-to-vehicle distance
increases/decreases in accor-
dance with vehicle speed.
1 Pressing the cancel switch can-
cels the speed control.
The speed control is also canceled
when the brake pedal is depressed.
2 Pressing the “+RES” switch
resumes the cruise control and
returns vehicle speed to the set
speed.
However, cruise control does not
resume when the vehicle speed is
approximately 25 km/h (16 mph) or
less.
When your vehicle is too close to a
vehicle ahead, and sufficient auto-
matic deceleration via the cruise
control is not possible, the display
will flash and the buzzer will sound
to alert the driver. An example of
this would be if another driver cuts
in front of you while you are follow-
ing a vehicle. Depress the brake
pedal to ensure an appropriate
vehicle-to-vehicle distance.
■Warnings may not occur when
In the following instances, warnings
may not occur even when the vehi-
cle-to-vehicle distance is small.

matically canceled for any reasons other
than the above, there may be a malfunc-
tion in the system. Contact any autho-
rized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
■The Radar Cruise Control with
Road Sign Assist may not operate
properly when
As the Radar Cruise Control with Road
Sign Assist may not operate properly in
conditions in which RSA may not oper-
ate or detect correctly (→P.229), when
using this function, make sure to check
the speed limit sign displayed.
In the following situations, the set speed
may not be changed to the recognized
speed limit by pressing and holding the “+RES”/“-SET” switch.
●If speed limit information is not avail-
able
●When the recognized speed limit is
the same as the set speed
●When the recognized speed limit is
outside of the speed range that the
dynamic radar cruise control system
can operate
■Brake operation
A brake operation sound may be heard
and the brake pedal response may
change, but these are not malfunctions.
■Warning messages and buzzers for
dynamic radar cruise control
Warning messages and buzzers are
used to indicate a system malfunction or
to inform the driver of the need for cau-
tion while driving. If a warning message
is shown on the multi-information dis-
play, read the message and follow the
instructions. (→P.191, 377)
■When the sensor may not be cor-
rectly detecting the vehicle ahead
In the case of the following and depend-
ing on the conditions, operate the brake
pedal when deceleration of the system
is insufficient or operate the accelerator
pedal when acceleration is required.
As the sensor may not be able to cor-
rectly detect these types of vehicles, the
approach warning (→P.219) may not be
activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the
same lane
●Vehicles with small rear ends (trailers
with no load on board, etc.)
