WARNING
■Hitch
Trailer hitch assemblies have different 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 ma ximum
weight rating specified for the trailer-hitch. Exceeding the ma ximum weight
rating set by the trailer-hitch manufacturer can cause an accid ent resulting
in death or serious personal injuries.
■ When towing a trailer
Toyota recommends trailers with brakes that conform to any appl icable fed-
eral and state/provincial regulations.
● If the gross trailer weight exceeds unbraked TWR, trailer brake s are
required. Toyota recommends trailers with brakes that conform t o all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle’s hydraulic system, as this will lo wer the vehi-
cle’s braking effectiveness.
● Never tow a trailer without using a safety chain securely attac hed to both
the trailer and the vehicle. If damage occurs to the coupling u nit or hitch
ball, there is danger of the trailer wandering into another lan e.
NOTICE
■When installing a trailer hitch
Use only the position recommended by your Toyota dealer. Do not install
the trailer hitch on the bumper; this may cause body damage.
■ Do not directly splice trailer lights
Do not directly splice trailer lights. Directly splicing traile r lights may damage
your vehicle’s electrical system and cause a malfunction.

1984-2. Driving procedures
If the engine is stopped with the shift lever in a position other than P,
the engine switch will not be turned off but instead be turned to
ACCESSORY mode. Perform the following procedure to turn the
switch off:
Check that the park ing brake is set.
Shift the shift lever to P.
Check that “Turn Power OFF” is displayed on the multi-informati on
display and then press the engine switch once.
Check that “Turn Power OFF” on the multi-information display is off.
■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minut es or IGNI-
TION ON mode (the engine is not running) for more than an hour with the
shift lever in P, the engine switch will automatically turn off. However, this
function cannot entirely prevent battery discharge. Do not leav e the vehicle
with the engine switch in ACCESSORY or IGNITION ON mode for lon g peri-
ods of time when the engine is not running.

2254-4. Refueling

Driving
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, tou ch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling, because sparks resulting from
static electricity can cause fuel vapors to ignite while refuel ing.
● 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 loosen ed.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out 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 p ossible ignition
hazard.
■ When refueling
Observe the following precautions to prevent fuel overflowing f rom the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically click s off.
● Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission c ontrol
system to operate abnormally, or damaging fuel system component s or the
vehicle’s painted surface.

Driving
■The Blind Spot Monitor function is operational when
●The BSM main switch is set to on.
● Vehicle speed is greater than approximately 10 mph (16 km/h)
■ The Blind Spot Monitor functio n will detect a vehicle when
● A vehicle in an adjacent lane overtakes the vehicle.
● Another vehicle enters the detection area when it changes lanes .
■ Conditions under which the Blind Spot Monitor function will not detect a
vehicle
The Blind Spot Monitor function is not designed to detect the f ollowing types
of vehicles and/or objects:
● Small motorcycles, bicycles, pedestrians, etc.
*
●Vehicles traveling in the opposite direction
● Guardrails, walls, signs, parked vehicles and similar stationar y objects
*
●Following vehicles that are in the same lane*
●Vehicles driving 2 lanes across from your vehicle*
*
: Depending on conditions, detection of a vehicle and/or object may occur
■ Conditions under which the Blind Spot Monitor function may not func-
tion correctly
● The Blind Spot Monitor function may not detect vehicles correct ly in the fol-
lowing conditions:
• During bad weather such as heavy rain, fog, snow, etc.
• When ice or mud, etc., is attached to the rear bumper
• When driving on a road surface that is wet due to rain, standi ng water,
etc.
• When there is a significant difference in speed between your v ehicle and
the vehicle that enters the detection area
• When a vehicle is in the detection area from a stop and remains in the detection area as your vehicle accelerates
• When driving up or down consecutive steep inclines, such as hills, a dip
in the road, etc.
• When multiple vehicles approach with only a small gap between each vehicle
• When vehicle lanes are wide, and the vehicle in the next lane is too far
away from your vehicle
• When the vehicle that enters the detection area is traveling a t about the
same speed as your vehicle
• When towing anything such as trailer, boat, etc.
• When there is a significant difference in height between your vehicle and
the vehicle that enters the detection area
• Directly after the BSM main switch is set to on
• When items such as a bicycle carrier are installed on the rear of the vehi-
cle

3024-5. Using the driving support systems
●Shifting to “4H” or “4L”
Automatic transmission
If the “4LO” indicator continues to blink when you operate the front-wheel
drive control switch to the “4H” or “4L” position, drive forwar d or backward
in a short distance, then stop the vehicle completely, shift the shift lever
securely to N and operate the switch again.
Manual transmission
If the “4LO” indicator continues to blink when you operate the front-wheel
drive control switch to the “4H” or “4L” position, drive forwar d or backward
in a short distance, then stop the vehicle completely, depress the clutch
pedal and operate the switch again.
If the indicator light continues to blink even if doing so, con tact your Toyota
dealer as soon as possible. There may be a trouble in the four- wheel drive
system.
■ Shifting to “4L”
VSC is automatically turned off.
■ Four-wheel drive usage frequency
You should drive in four-wheel drive for at least 10 miles (16 km) each month.
This will assure that the front drive components are lubricated .
WARNING
■Caution while driving
● Never shift the front-wheel drive control switch from “2WD” to “4H” if the
wheels are slipping.
Stop the slipping or spinning before shifting.
● For normal driving on dry and hard surface roads, use “2WD” pos ition.
Driving on dry and hard surface roads in “4H” or “4L” position may cause
drive component oil leakage, seizure, or other problems resulti ng in an
accident. Further, it may cause tire wear and increased fuel consumption.
● Avoid turning suddenly in “4H” or “4L” position. If you do turn suddenly, the
difference in turning speeds between the front and rear wheels may have
a similar effect to braking, thus making driving difficult.
● Do not shift the front-wheel drive control switch when the vehicle is turning
or when its wheels are spinning freely off the ground.
