2-4. Using other driving systems
4RUNNER_U_(L/O_0808)
Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehicle.
n 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.
n Brake Assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
n VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
n TRAC (Traction Control)
Maintains drive power and prevents the rear wheels (2WD models and
H2 mode on Multi-mode 4WD models) or all wheels (4WD models
except on L4 mode) from spinning when starting the vehicle or acceler-
ating on slippery roads.
n A-TRAC (Active Traction Control) for L4 mode on 4WD mod-
els (vehicles with the A-TRAC switch except when the cen-
ter differential lock is locked)
Maintains drive power and prevents the all wheels from spinning when
starting the vehicle or accelerating on slippery roads.
n Hill-start assist control (if equipped)
Helps prevent the vehicle from rolling backwards when starting on an
incline or slippery slope. It operates for approximately 5 seconds at
maximum.
