tion correctly
●The Blind Spot Monitor function may not detect vehicles correctly 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, standing water,
etc.
• When there is a significant difference in speed between your vehicle 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 at 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 ar e installed on the rear of the vehi-
cle

2224-5. Using the driving support systems
●Instances of the Blind Spot Monitor function unnecessarily detecting a vehi-
cle and/or object may increase under the following conditions:
• When there is only a short distance between your vehicle and a guardrail,
wall, etc.
• When there is only a short distance between your vehicle and a following
vehicle
• When vehicle lanes are narrow and a vehicle driving 2 lanes across from your vehicle enters the detection area
• When items such as a bicycle carrier ar e installed on the rear of the vehi-
cle
The Rear Cross Traffic Alert functions when your vehicle is in reverse.
It can detect other vehicles approaching from the right or left rear of
the vehicle. It uses radar sensors to alert the driver of the other vehi-
cle’s existence through fl ashing the outside rear view mirror indicators
and sounding a buzzer.

The areas that vehicles can be detected in are outlined below.
To give the driver a more consistent time to react, the buzzer can alert
for faster vehicles from farther away.
Example:
CAUTION
■ Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Rear Cross Traffic Alert function is only an assist and is not a replace-
ment for careful driving. Driver must be careful when backing up, even
when using Rear Cross Traffic Alert function. The driver’s own visual confir-
mation of behind you and your vehicle is necessary and be sure there are
no pedestrians, other vehicles, etc., before backing up. Failure to do so
could cause death or serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

Driving
Four-wheel drive system
Use the front-wheel drive control switch to select the following transfer
modes:
“2WD” (high speed position, two-wheel drive)
Use this for normal driving on dry hard-surfaced roads. This position
gives greater economy, quietest ride and least wear.
“4H” (high speed position, four-wheel drive)
Use this for driving only on tracks that permit the tires slide, like off-road,
icy or snow-covered roads. This pos ition provides greater traction than
two-wheel drive.
The “4HI” indicator will come on.
“4L” (low speed position, four-wheel drive)
Use this for maximum power and traction. Use “4L” for climbing or
descending steep hills, off-road driving, and hard pulling in sand, mud or
deep snow.
The “4LO” indicator will come on.

Driving
■When the front-wheel drive cont rol switch is shifted to “4L”
VSC is automatically turned off.
■ If the “4HI” indicator flashes
The transfer mode may not successfully change. Drive straight ahead while
accelerating or decelerating, or drive in reverse.
■ If the “4LO” indicator continues to flash
The transfer mode may not successful ly change. Operate the front-wheel
drive control switch again.
■ If the “4LO” indicator continu es to flash and a buzzer sounds
The shift lever is not in N and/or the vehicle is moving. Stop the vehicle com-
pletely, shift the shift lever to N and make sure that the indicator stops flash-
ing.
■ If the “4HI” or “4LO” indicator flashes rapidly
There may be a malfunction in the four-wheel drive system. Have the vehicle
inspected by your Toyota dealer immediately.
■ Four-wheel drive usage frequency
You should drive in four-wheel drive fo r at least 10 miles (16 km) each month.
This will assure that the front drive components are lubricated.
CAUTION
■ Shifting the front-wheel dr ive control switch from “2WD” to “4H” while
driving
Never operate the front-wheel drive control switch if the wheels are slipping.
Stop the slipping or spinning before shifting.
■ When the vehicle is parked
If the shift lever is moved before the “4LO” indicator turns on/off, the transfer
mode may not be shifted completely. The transfer mode disengages both
the front and rear driveshafts from the powertrain and allows the vehicle to
move regardless of the shift position. (At this time, the indicator blinks and
the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode before placing transmission in P.

2284-5. Using the driving support systems
AUTO LSD system
The system can be used on 2WD models and in 2WD mode on 4WD
models.
The system is activated when dr iving at a speed under 62 mph (100
km/h).
The AUTO LSD system w ill be activated with the following two proce-
dures.
Press the VSC off switch briefly.
The “AUTO LSD” indicator will
come on.
To turn off the system, push the
switch again.
Stop the vehicle completely, and
press the VSC off switch for more
than 3 seconds.
The VSC off and “AUTO LSD” indi-
cators will come on.
To turn off the system, push the
switch again.
The AUTO LSD system aids tract ion by using the traction con-
trol system to control engine performance and braking when
one of the rear wheels begins to spin.
The system should be used only when one of the rear wheels
spinning occurs in a ditch or rough surface.
System operation

Driving
If the rear wheels spin, the slip
indicator flashes to indicate that
the AUTO LSD system has con-
trolled the spinning of the rear
wheels.
■If the engine is turned off and restarted
The AUTO LSD system and the indicators are automatically turned off.
■ If the brake system overheats
The AUTO LSD system will cease operation, and the slip indicator will
change from flashing to being on continuously to alert the driver. Stop the
vehicle in a safe place. (There is no problem with continuing normal driving.)
The system will be automatically restored after a short time.
When the AUTO LSD system is operating
CAUTION
■To avoid an accident
● Do not use the AUTO LSD system in conditions other than the above.
A much greater steering effort and more careful cornering control will be
required.
● Do not drive with the AUTO LSD system continuously turned on.

2304-5. Using the driving support systems
Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake
pressure for individual wheels and reducing engine torque when
trailer sway is detected.
Trailer Sway Control is part of the VSC system and will not operate if
VSC system is turned off or experiences a malfunction.
◆TRAC (Traction Control) for 2WD models and 2WD mode on
4WD models
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆A-TRAC (Active Traction Control) for 4WD mode on 4WD mod-
els
Maintains drive power and prevents all wheels from spinning when
starting the vehicle or accelerating on slippery roads.
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.
