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 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 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 the filler neck and cau se 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 from 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 components or the
vehicle’s painted surface.

●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 system 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

●Vehicles driving 2 lanes across from your vehicle*
*
: Depending on conditions, detection of a vehicle and/or object may occur
■ Conditions under which the system may not function 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-

●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 th e 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, contact 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.

WARNING
■Caution while driving

Injuries may result in the event of an accident or sudden braki ng.
■ When the deck hooks are not in use
To avoid injury, always return the deck hooks to their stowed positions.
■ Tie-down cleat precautions
● Properly install and tighten the tie-down cleats into the deck rail system.
Failure to properly install and tighten the tie-down cleats can cause cargo
to become unsecured. Unsecured cargo can cause injury when the vehi-
cle is in motion.

Failure to properly secure cargo can cause injury when the vehicle is in
motion.
● Applying loads at an angle to the tie-down cleat greater than 4 5° or loads
greater than 220 lb. (100 kg) may cause damage to the deck, deck rail
system, tie-down cleat and/or the cargo.
● Do not exceed a total tensile load of 440 lb. (200 kg) per deck rail.
● Do not install more than the following number of tie-down cleats per deck
rail:
• Side rail:
Short deck—Max. 3 locations
Long deck—Max. 4 locations
● Confirm cargo and cleats do not interfere with tonneau cover latching and
completely closing.
