WARNING

■

Trailer towing precautions

To tow a trailer safely, use 

extreme care and drive the vehi-

cle in accordance with the trailer’s 

characteristics and operating con-

ditions. Failure to do so could 

cause an accident resulting in 

death or serious injury. Vehicle 

stability and braking performance 

are affected by trailer stability, 

brake setting and performance, 

and the hitch. Your vehicle will 

handle differently when towing a 

trailer.

■

To avoid accident or injury

●

Do not exceed the TWR, 

unbraked TWR, GCWR, GVWR 

or GAWR.

●

Adjust the tongue weight within 

the appropriate range. Place 

heavier loads as close to the 

trailer axle as possible.

●

Do not exceed 65 mph (104 

km/h), the posted towing speed 

limit or the speed limit for your 

trailer as set forth in your trailer 

owner’s manual, whichever is 

lowest. Slow down sufficiently 

before making a turn, in cross 

winds, on wet or slippery sur-

face, etc. to help avoid an acci-

dent. If you experience a 

vehicle-trailer instability from 

reducing a certain speed, slow 

down and make sure you keep 

your vehicle speed under the 

speed of which you experience 

the instability.

●

Do not make jerky, abrupt or 

sharp turns.

●

Do not apply the brakes sud-

denly as you may skid, resulting 

in jackknifing and loss of vehicle 

control. This is especially true 

on wet or slippery surfaces.

●

Do not exceed the trailer hitch 

assembly weight, gross vehicle 

weight, gross axle weight and 

trailer tongue weight capacities.

●

Do not use dynamic radar 

cruise control with full-speed 

range when towing.

●

Slow down and downshift 

before descending steep or long 

downhill grades. Do not make 

sudden downshifts while 

descending steep or long down-

hill grades.

●

Vehicle-trailer instability is more 

likely on steep long downhills. 

Before descending steep or 

long downhill grades, slow 

down and downshift. Do not 

make sudden downshifts when 

descending steep or long down-

hill grades. Avoid holding the 

brake pedal down too long or 

applying the brakes too fre-

quently. This could cause the 

brakes to overheat and result in 

reduced braking efficiency.

●

Do not tow a trailer when the 

compact spare tire is installed 

on your vehicle.

■

When towing a trailer

Toyota recommends trailers with 

brakes that conform to any appli-

cable federal and state/provincial 

regulations.

●

If the gross trailer weight 

exceeds unbraked TWR, trailer 

brakes are required. Toyota rec-

ommends trailers with brakes 

that conform to all applicable 

federal and state/provincial reg-

ulations.

●

Never tap into your vehicle’s 

hydraulic system, as this will 

lower the vehicle’s braking 

effectiveness.

GCWR (Gross Combination 
Weight Rating)

The maximum allowable gross 
combination weight. The gross 
combination weight is the sum 
of the total vehicle weight 
(including the occupants, cargo 
and any optional equipment 
installed on the vehicle) and the 
weight of the trailer being towed 
(including the cargo in the 
trailer).

■

GVWR (Gross Vehicle 
Weight Rating)

The maximum allowable gross 
vehicle weight. The gross vehi-
cle weight is the total weight of 
the vehicle. When towing a 
trailer, it is the sum of the vehi-
cle weight (including the occu-
pants, cargo and any optional 

equipment installed on the vehi-
cle) and the tongue weight.

■

GAWR (Gross Axle Weight 
Rating)

The maximum allowable gross 
axle weight. The gross axle 
weight is the load placed on 
each axle (front and rear).

Front GAWR

Rear GAWR

■

TWR (Trailer Weight Rating)

The maximum allowable gross 
trailer weight. The gross trailer 
weight is the sum of the trailer

WARNING

●

Never tow a trailer without using 

a safety chain securely attached 

to both the trailer and the vehi-

cle. If damage occurs to the 

coupling unit or hitch ball, there 

is danger of the trailer wander-

ing into another lane.

Hitch

Trailer hitch assemblies have dif-

ferent weight capacities estab-

lished by the hitch manufacturer. 

Even though the vehicle may be 

physically capable of towing a 

higher weight, the operator must 

determine the maximum weight 

rating of the particular hitch 

assembly and never exceed the 

maximum weight rating specified 

for the trailer-hitch. Exceeding the 

maximum weight rating set by the 

trailer-hitch manufacturer can 

cause an accident resulting in 

death or serious personal injuries.

NOTICE

■

When installing a trailer hitch

Use only the position recom-

mended by your Toyota dealer. 

Do not install the trailer hitch on 

the bumper; this may cause body 

damage.

Driving

Please consult your dealer 
when installing trailer lights, as 
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 
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 

Connecting trailer lights

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

276

5-1. Before driving

vehicle control. This is espe-
cially true on wet or slippery 
surfaces.



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, when using engine 
braking, do not use the trans-
mission 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 
high coolant temperature 
warning light indicates over-
heating, immediately turn off 
the air conditioning (if in use), 
pull your vehicle off the road 
and stop in a safe spot. 
(



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.

■

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 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 45 mph 

(72 km/h) when towing a trailer, and 

avoid full throttle acceleration.

■

Maintenance

●

If you tow a trailer, your vehicle 

will require more frequent 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 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 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 

278

5-1. Before driving

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 4 

wheels on the ground.

■

To prevent causing serious 

damage to the transmission 

and AWD system

Never tow this vehicle with any of 

the wheels on the ground. This 

may cause serious damage to the 

transmission and AWD system.

WARNING

■

When refueling the vehicle

Observe the following precautions 

while refueling the vehicle. Failure 

to do so may result in death or 

serious injury.

●

After exiting the vehicle and 

before opening the fuel door, 

touch an unpainted metal sur-

face to discharge any static 

electricity. It is important to dis-

charge static electricity before 

refueling because sparks result-

ing from static electricity can 

cause fuel vapors to ignite while 

refueling.

●

Always hold the grips on the 

fuel tank cap and turn it slowly 

to remove it.

A whooshing sound may be 

heard when the fuel tank cap is 

loosened. Wait until the sound 

cannot be heard before fully 

removing the cap. In hot 

weather, pressurized fuel may 

spray out of the filler neck and 

cause injury.

●

Do not allow anyone that has 

not discharged static electricity 

from their body to come close to 

an open fuel tank.

●

Do not inhale vaporized fuel.

Fuel contains substances that 

are harmful if inhaled.

●

Do not smoke while refueling 

the vehicle.

Doing so may cause the fuel to 

ignite and cause a fire.

●

Do not return to the vehicle or 

touch any person or object that 

is statically charged. This may 

cause static electricity to build 

up, resulting in a possible igni-

tion hazard.

WARNING

■

When refueling

Observe the following precautions 

to prevent fuel overflowing from 

the fuel tank:

●

Securely insert the fuel nozzle 

into the fuel filler neck.

●

Stop filling the tank after the fuel 

nozzle automatically clicks off.

●

Do not top off the fuel tank.

NOTICE

■

Refueling

●

Finish refueling within 30 min-

utes. If more than 30 minutes 

passes, the internal valve 

closes. In this condition, fuel 

may overflow during the refuel-

ing process. Press the fuel filler 

door opener switch again.

●

Do not spill fuel during refueling.

Doing so may damage the vehi-

cle, such as causing the emis-

sion control system to operate 

abnormally or damaging fuel 

system components or the vehi-

cle’s painted surface.

the vehicle. When the sys-
tem determines that the 
possibility of a frontal colli-
sion with an object is high, 
a warning operates to urge 
the driver to take evasive 
action and the potential 
brake pressure is increased 
to help the driver avoid the 
collision. If the system 
determines that the possi-
bility of a frontal collision 
with an object is extremely 
high, the brakes are auto-
matically applied to help 
avoid the collision or help 
reduce the impact of the

Limitations of the pre-colli-

sion system

●

The driver is solely responsible 

for safe driving. Always drive 

safely, taking care to observe 

your surroundings. 

Do not use the pre-collision sys-

tem instead of normal braking 

operations under any circum-

stances. This system will not 

prevent collisions or lessen col-

lision damage or injury in every 

situation. Do not overly rely on 

this system. Failure to do so 

may lead to an accident, result-

ing in death or serious injury.

●

Although this system is 

designed to help avoid a colli-

sion or help reduce the impact 

of the collision, its effectiveness 

may change according to vari-

ous conditions, therefore the 

system may not always be able 

to achieve the same level of 

performance. 

Read the following conditions 

carefully. Do not overly rely on 

this system and always drive 

carefully.

• Conditions under which the sys-

tem may operate even if there is 

no possibility of a collision: 



P.319

• Conditions under which the sys-

tem may not operate properly: 



P.320

●

Do not attempt to test the oper-

ation of the pre-collision system 

yourself.

Depending on the objects used 

for testing (dummies, card-

board objects imitating detect-

able objects, etc.), the system 

may not operate properly, pos-

sibly leading to an accident.

■

Pre-collision braking

●

When the pre-collision braking 

function is operating, a large 

amount of braking force will be 

applied.

●

If the vehicle is stopped by the 

operation of the pre-collision 

braking function, the pre-colli-

sion braking function operation 

will be canceled after approxi-

mately 2 seconds. Depress the 

brake pedal as necessary.

●

The pre-collision braking func-

tion may not operate if certain 

operations are performed by the 

driver. If the accelerator pedal is 

being depressed strongly or the 

steering wheel is being turned, 

the system may determine that 

the driver is taking evasive 

action and possibly prevent the 

pre-collision braking function 

from operating.

●

In some situations, while the 

pre-collision braking function is 

operating, operation of the func-

tion may be canceled if the 

accelerator pedal is depressed 

strongly or the steering wheel is 

turned and the system deter-

mines that the driver is taking 

evasive action.

●

If the brake pedal is being 

depressed, the system may 

determine that the driver is tak-

ing evasive action and possibly 

delay the operation timing of the 

pre-collision braking function.

■

When to disable the pre-colli-

Pre-collision braking

The system may not operate in the following situations:

●

If a 12-volt battery terminal has been disconnected and reconnected and 

then the vehicle has not been driven for a certain amount of time

●

If the shift lever is in R

●

When the VSC OFF indicator is illuminated (only the pre-collision warning 

function will be operational)

■

Object detection function

The system detects objects based 

on their size, profile, motion, etc. 

However, an object may not be 

detected depending on the sur-

rounding brightness and the motion, 

posture, and angle of the detected 

object, preventing the system from 

operating properly. (

the pre-collision braking function is 

operating, it will be canceled:

●

The accelerator pedal is 

depressed strongly.

●

The steering wheel is turned 

sharply or abruptly.

LTA (Lane Tracing 

Assist)

When driving on highways 
and freeways with white 
(yellow) lane lines, this 
function alerts the driver 
when the vehicle might 
depart from its lane or 
course

*

 and provides assis-

tance by operating the 
steering wheel to keep the 
vehicle in its lane or

. Furthermore, the 

system provides steering 
assistance when dynamic 
radar cruise control with 
full-speed range is operat-
ing to keep the vehicle in its 
lane.

The LTA system recognizes

WARNING

■

Before using LTA system

●

Do not rely solely upon the LTA 

system. The LTA system does 

not automatically drive the vehi-

cle 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 atten-

tion to the surrounding condi-

tions and operating the steering 

wheel to correct 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 

driving operations and pay care-

ful attention may lead to an 

accident, resulting in death or 

serious injury.

Temporary cancelation of func-

tions

●

When operation conditions are no 

longer met, a function may be 

temporarily canceled. However, 

when the operation conditions are 

met again, operation of the func-

tion is automatically restored. 

(



P.329)

●

If the operation conditions 

(



P.329) are no longer met while 

the lane centering function is 

operating, the steering wheel may 

vibrate and the buzzer may sound 

to indicate that the function has 

been temporarily canceled. How-

ever, if the “Alert” customization 

setting is set to “Steering wheel 

vibration”, the system will notify 

the driver by vibrating the steering 

wheel instead of sounding the 

buzzer.

●

Depending on the vehicle speed, 

lane departure situation, road con-

ditions, etc., the driver may not 

feel the function is operating or 

the function may not operate at 

all.

●

The steering control of the func-

tion is overridden by the driver’s 

steering wheel operation.

●

Do not attempt to test the opera-

tion of the steering assist function.

■

Lane departure alert function

●

The warning buzzer may be diffi-

cult to hear due to external noise, 

audio playback, etc. Also, it may 

be difficult to feel steering wheel 

vibrations due to the road condi-

tions, etc.

●

If the edge of the course

*

 is not 

clear or straight, the lane depar-

ture alert function may not oper-

ate.

●

It may not be possible for the sys-

tem to determine if there is a dan-

ger of a collision with a vehicle in 

an adjacent lane.

Hands off steering wheel warn-

ing

In the following situations, a warning 

message urging the driver to hold 

the steering wheel and the symbol 

shown in the illustration are dis-

played on the multi-information dis-

play to warn the driver. The warning 

stops when the system determines 

that the driver holds the steering 

wheel. Always keep your hands on 

the steering wheel when using this 

system, regardless of warnings.

●

When the system determines that 

the driver is driving without hold-

ing the steering wheel while the 

system is operating 

If the driver continues to keep their 
hands off of the steering wheel, the 
buzzer sounds, the driver is warned 
and the function is temporarily can-
celed. This warning also operates in 
the same way when the driver con-
tinuously operates the steering 
wheel only a small amount.
The buzzer also sounds even if the 
alert type is set to “Steering wheel 
vibration”.

●

the vehicle may not turn and 

instead depart from its lane while

5-5. Using the driving support systems

Depending on the vehicle condition 
and road conditions, the warning 
may not operate. Also, if the system 
determines that the vehicle is driv-
ing around a curve, warnings will 
occur earlier than during straight-
lane driving.

●

When the system determines that 

the driver is driving without hold-

ing the steering wheel while the 

steering wheel assist of the steer-

ing assist function is operating.

If the driver continues to keep their 
hands off of the steering wheel and 
the steering wheel assist is operat-
ing, the buzzer sounds and the 
driver is warned. Each time the 
buzzer sounds, the continuing time 
of the buzzer becomes longer. 
The buzzer also sounds even if the 
alert type is set to “Steering wheel 
vibration”.

Vehicle sway warning function

When the system determines that 

the vehicle is swaying while the 

vehicle sway warning function is 

operating, a buzzer sounds and a 

warning message urging the driver 

to rest and the symbol shown in the 

illustration are simultaneously dis-

played on the multi-information dis-

play.

Depending on the vehicle and road 

conditions, the warning may not 

operate.

■

Warning message

If the following warning message is 

displayed on the multi-information 

display and the LTA indicator illumi-

nates in orange, follow the appropri-

ate troubleshooting procedure. Also, 

if a different warning message is 

displayed, follow the instructions 

displayed on the screen.

Dealer”

The system may not be operating 
properly. Have the vehicle inspected 
by your Toyota dealer.

●

“LTA Unavailable”

The system is temporarily canceled 
due to a malfunction in a sensor 
other than the front camera. Turn 
the LTA system off, wait for a little 
while, and then turn the LTA system 
back on.

●

“LTA Unavailable at Current
