●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 are 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.

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.

● The shift lever is in R.
● Vehicle speed is less than approximately 5 mph (8 km/h).
● Approaching vehicle speed is between approximately 5 mph (8 km/h) and
18 mph (28 km/h).
■ Conditions under which the Rear Cr oss Traffic Alert function will not
detect a vehicle
The Rear Cross Traffic Alert function is not designed to detect the following
types of vehicles and/or objects.

*
●Vehicles backing up in the parking space next to your vehicle*
*
: Depending on conditions, detection of a vehicle and/or object may occur.
■ Conditions under which the Rear Cr oss Traffic Alert function may not
function correctly
The Rear Cross Traffic Alert function may not detect vehicles correctly in the
following conditions.
● When ice or mud, etc., is attached to the rear bumper
● During bad weather such as heavy rain, fog, snow, etc.
● When multiple vehicles approach continuously
● Shallow angle parking
● When a vehicle is approaching at high speed
● When parking on a steep incline, such as hills, a dip in the road, etc.
● Directly after the BSM main switch is set to on
● Directly after the engine is started with the BSM main switch on
● When towing a trailer
● Vehicles that the sensors cannot detect
because of obstacles

2284-5. Using the driving support systems
Four-wheel drive system
Use the front-wheel drive control swit ch 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 position 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.

■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 continues 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 for at least 10 miles (16 km) each month.
This will assure that the front drive components are lubricated.
CAUTION
■ Shifting the front-wheel drive 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.

AUTO LSD system
The system can be used on 2WD models and in 2WD mode on 4WD
models.
The system is activated when driving at a speed under 62 mph (100
km/h).
The AUTO LSD system will be activa ted 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 trac tion 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

2324-5. Using the driving support systems
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.
