2-4. Using other driving systems
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.
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■Enhanced VSC (Enhanced Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■TRAC (Traction Control)
Maintains drive power and prevents the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■AUTO LSD function (2WD models)
The AUTO LSD function is activated when the system is in TRAC off
mode. It operates when one of the drive wheels is spinning, such as
when the wheel is spinning freely on ice or mud. The system applies
the brakes to the spinning wheel and transfers some of the torque to
the other wheel to secure drive power.
■Active torque control 4WD system (4WD models)
Automatically switches from front-wheel drive to four-wheel drive
(4WD) according to the driving conditions, helping to ensure reliable
handling and stability. Examples of conditions where the system will
switch to 4WD are when cornering, going uphill, starting off or acceler-
ating, and when the road surface is slippery due to snow, rain, etc.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

2-4. Using other driving systems
Four-wheel drive lock switch (4WD models)
■Four-wheel drive lock mode can be operated when
Vehicles without smart key system
The engine switch is in the “ON” position. Vehicles with smart key system
The “ENGINE START STOP” switch is in IGNITION ON mode.
■ Four-wheel drive lock mode
●Four-wheel drive lock mode is canceled when the brakes are applied to
ensure the ABS and Enhanced VSC systems operate effectively.
● Four-wheel drive lock mode is canceled when the vehicle speed exceeds
25 mph (40 km/h).
Four-wheel drive lock mode can be used when a large amount of
drive power needs to be applied to all the wheels, such as when the
vehicle gets stuck in mud and you need to free it.
Press the switch.
The torque of the engine is dis-
tributed to the rear wheels to
the maximum extent possible
in accordance with driving con-
ditions.
Pressing the switch again can-
cels four-wheel drive lock
mode and returns the active
torque control 4WD system to
normal mode. (P. 180)

CAUTION
■Replacing a flat tire
Observe the following precautions to reduce the risk of death or serious
injury:
●Do not try to remove the ornament by hand. Take due care in handling
the ornament to avoid unexpected personal injury.
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing a
serious accident. Remove any oil or grease from the wheel bolts or
wheel nuts.
●Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103
N
•m, 10.5 kgf•m) as soon as possible after changing wheels.
Failure to follow these precautions could cause the nuts to loosen and
the wheel may fall off, which could lead to an accident causing death
or serious injury.
●Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the ve hicle is moving.
●Make sure that the rubber rings are not installed to the wheel nuts for
aluminum wheel. Otherwise, the nuts may become loose and the
wheel may fall off, which may cause a serious accident.
