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 front wheels (2WD models) or
four wheels (4WD models) from sp inning when starting the vehicle or
accelerating on slippery roads.
■ Hill-start assist control
P. 223
■Downhill assist control system (4WD models only)
P. 225
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

5-1. Essential information
Installing towing eyelet
Remove the eyelet cover while
pushing it.
Insert the towing eyelet into the
hole and tighten partially by
hand.
CAUTION
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelets and the cables or chains.
● If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.
NOTICE
■To prevent causing serious dama ge to the transmission
Never tow this vehicle from the rear with the front wheels on the ground.
This may cause serious damage to the transmission.
