■Locking the rear differential
The following systems do not operate w hen the rear differential is locked.
It is normal operation for the ABS warning light, VSC OFF indicator (if
equipped) and “TRC OFF” indicator (if equipped) to be on at this time.
•ABS
• Brake assist (if equipped)
• VSC (if equipped)
• TRC (if equipped)
■ For easy unlocking
Slightly turn the steering wheel in either direction while the vehicle is in
motion.
■ Automatic unlocking feature (4WD models)
Shift the front drive control lever to H2 or H4.
Never forget to turn off the switch after using this feature.
■ After unlocking the rear differential
Check that the indicator goes off.
CAUTION
■To avoid an accident
Failure to observe the following precautions may result in an accident.
● Do not use the rear differential lock system except when wheel spinning
occurs in a ditch or on a slippery or rugged surface. Large steering effort
and careful cornering control will be required.
● Do not lock the rear differential until the wheels have stopped spinning.
Otherwise, the vehicle may move in an unexpected direction when the dif-
ferential lock is engaged, resulting in an accident. This may also lead to
possible damage to rear differential lock component parts.
● Do not drive over 8 km/h (5 mph) when the differential is locked.
● Do not keep driving with the rear differential lock switch on.

Driving assist systems
◆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
◆Brake assist (if equipped)
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) (if equipped)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces
◆TRC (Traction Control) (if equipped)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
◆LSD (Limited Slip Differential) (if equipped)
Helps traction when one rear wheel begins to spin by automatically trans-
mitting driving force to the other rear wheel
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.

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 TRC/VSC sys-
tems are operating.
If the vehicle gets stuck in fresh snow or mud, the TRC/VSC systems
may reduce power from the engine to the wheels. You may need to
turn the system off to enable you to rock the vehicle in order to free it.

Reactivation of the TRC system linked to vehicle speed
When only the TRC system is turned off, the TRC system will turn on when
vehicle speed increases. However, when both TRC and VSC systems are
turned off, the systems will not turn on even when vehicle speed increases.
■ If the slip indicator light comes on...
It may indicate a malfunction in the VSC and TRC. Consult any authorized
Toyota dealer or repairer, or another duly qualified and equipped professional.
CAUTION
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten t he vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
