■System malfunction
In case of a system malfunction, the following may occur:
● The downhill assist control system indicator flashes in a situation other
than those listed above.
● The downhill assist control system indicator does not come on when the
engine switch is turned to the “ON” position (vehicles without a smart key
system) or the “ENGINE START STOP” switch is turned to IGNITION ON
mode (vehicles with a smart key system).
Have your vehicle inspected by your Toyota dealer.
CAUTION
■ Conditions which may affect the downhill assist control system opera-
tion
● Do not rely too heavily on the downhill assist control system. On extremely
steep inclines, icy surfaces or muddy roads, the vehicle may slip and the
system may not be able to maintain the constant low vehicle speed of
about 3 mph (5 km/h), leading to an accident causing death or serious
injury.
● Do not shift the shift lever to R while driving forward, or to D while driving
backward. Doing so may cause the wheels to lock up, leading to an acci-
dent causing death or serious injury. In addition, excessive stress will be
applied to the automatic transmission, possibly resulting in damage.

● The engine is running.
● The shift lever is in any position other than P or N.
● The front-wheel drive control lever or switch is in L4.
● The driver’s door is closed.

■Crawl Control is temp orarily canceled when
Vehicle speed exceeds 15 mph (25 km/h). The Crawl Control indicator
flashes until the vehicle speed is reduced.
■ Automatic system cancelation
In the following situations, the system will cease operation and a buzzer will
sound to alert the driver. The Crawl Control indicator will flash until the sys-
tem is turned off completely.
● When the shift lever is shifted to P or N
● When the front-wheel drive control lever or switch is shifted to H4
● When the driver’s door is opened
● When the system is malfunctioning
● When the brake system overheats
Stop the vehicle in a safe place. (There is no problem with continuing
normal driving.)
● When the automatic transmission system overheats
Stop the vehicle in a safe place until the automatic transmission fluid tem-
perature warning light goes off.
■ Sounds and vibrations caused by the Crawl Control system
● A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in Crawl Control system.
● Either of the following conditions may occur when the Crawl Control sys-
tem is operating. None of these indicates that a malfunction has
occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.

■Multi-terrain Select is temporarily canceled when
The front-wheel drive control lever or switch is shifted to H4 when Multi-ter-
rain Select is in ROCK, MOGUL or LOOSE ROCK mode. The mode indica-
tor will flash until the lever is shifted back to L4.
■ If the Multi-terrain Select indicator continues to flash
This may indicate a malfunction in the Multi-terrain Select system.
In this case, Multi-terrain Select is automatically canceled. Have your vehicle
inspected by your Toyota dealer.
■ If the Multi-terrain Select indicator goes off while Multi-terrain Select is
operating
● One of the vehicle systems related to Multi-terrain Select may be mal-
functioning.
Have your vehicle inspected by your Toyota dealer.
●
The brake actuator may be at risk of overheating.
A buzzer will sound, the “A-TRAC” indicator will go off and the “TRAC
OFF” indicator will come on. Stop the vehicle in a safe place. Refrain
from using Multi-terrain Select until the “A-TRAC” indicator comes back
on and the “TRAC OFF” indicator goes off. (The vehicle can still be
driven, even if Multi-terrain Select is inoperative.)
In the above cases, Multi-terrain Select is automatically canceled.

Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily when operating the vehicle.
■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
■Multi Terrain ABS (Anti-lock Brake System) (if equipped)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface, or in off-
road conditions (such as rough roads, sand and mud)
The Multi Terrain ABS operates in syn chronization with the Multi-terrain
Select.
■ 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
■TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
■Hill-start assist control (if equipped)
Helps to prevent the vehicle from rolling backward when starting on an
incline or slippery slope
■LSD (Limited Slip Differential) (if equipped)
Transfers drive power to the rear tires when front tires spin, and vice
versa, in order to improve traction

When the TRAC/VSC systems are operating (2WD models)
If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator flashes to
indicate that the TRAC/VSC sys-
tems are operating.
When the TRAC/VSC/hill-start assist control systems are
operating (4WD models)If the vehicle is in danger of slip-
ping or rolling backward when
starting on an incline, or if any of
the drive wheels spins, the slip
indicator flashes to indicate that
the TRAC/VSC/hill-start assist
control systems are operating.
The stop lights and high mounted
stoplight turn on and a buzzer
(intermittent) sounds when the
hill-start assist control system is
operating.
■KDSS (Kinetic Dynamic Suspension System) (if equipped)
Enhances ride comfort and handling response by using a hydraulic
control system to control the suspension stabilizer bars in response to
road surface and driving conditions dur ing cornering or off-road driving
