CONTROLS AND INSTRUMENTS
The ESC improves safety and a vehicle's stability. The ESC controls engine power
and applies the brakes to the wheels that need it in order to suppress wheelspin
when starting or accelerating on slippery road surfaces, maintain drive power, prevent
skidding to the side, and improve vehicle stability. The ESC has various sensors that
detect rapid changes in the vehicle conditions while driving. The traction control system
(TCS) controls engine power and applies the brakes to the wheels that need it in order
to suppress wheelspin when starting or accelerating.
Normally, both the ESC and TCS activate automatically when the engine is started.
By using the ESC OFF switch, the ESC can be canceled (operation stopped status) or
only the function of the TCS can be canceled (operation stopped status).
CAUTION
• When the 4WD switch is set to 4L (4WD low) (models with 4WD), the ESC
warning light, ESC OFF indicator light, and TCS OFF indicator light come on,
and the ESC and TCS engine power control function will not activate. However,
in this case TCS brake control function will still activate.
• When the rear differential lock is operating (models with rear differential lock),
the ESC and TCS does not activate.
• When the ESC is operated, the ESC warning light flashes.
• The ESC warning light will also flash when only the TCS function is operating.
• When the ESC warning light is flashing, the road surface is slippery or
acceleration is too fast. Loosen pressure on the accelerator pedal and drive
conservatively.
• The ESC warning light may also flash when fully depressing the accelerator
pedal on roads that are not slippery such as dry asphalt roads. This is a normal
condition that predicts slipping and operates control.
• Even with an ESC-equipped model, when driving on a snowy or icy road,
install tire chains or winter tires, and carefully drive the vehicle. The ESC is not
a device for drastically improving the vehicle stability when driving or starting
performance, so drive carefully on snowy or icy roads.
• When tire chains are installed, it may be easier for you to start the vehicle to
move on an icy slope if just the TCS is canceled. Be aware, however, that TCS
deactivation will result in reduced vehicle stability.
• Install tires of the specified size, same brand, same type and same tread design
(including winter tires) on all wheels. In addition, do not install or use tires
with significantly varying degrees of wear. If tires other than the specified size,
different types, or tires with significantly varying degrees of wear are used, the
ESC may not operate properly.
