●The shift lever is in the D or range 4 or higher of S has been selected.
(vehicles with an automatic transmission)
● Range 4 or higher has been selected by using the paddle shift switch.
(vehicles with an automatic transmission)
● Vehicle speed is above approximately 25 mph (40 km/h).
■ Accelerating after setting the vehicle speed
●The vehicle can be accelerated normally. After acceleration, the set
speed resumes.
● Even without canceling the cruise control, the set speed can be
increased by first accelerating the vehicle to the desired speed and then
pushing the lever down to set the new speed.
■ Automatic cruise control cancelation
Cruise control will stop maintaining the vehicle speed in any of the following
situations.
●Actual vehicle speed falls more than approximately 10 mph (16 km/h)
below the preset vehicle speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed is below approximately 25 mph (40 km/h).
● VSC is activated.
■ If the cruise control indicator light flashes
Press the “ON-OFF” button once to deactivate the system, and then press

Driving assist systems
When the TRAC/VSC systems are operating
The slip indicator light will flash
while the TRAC/VSC systems
are operating.
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 heavi ly 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
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
■TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

Disabling the TRAC systemIf the vehicle gets stuck in mud, dirt or snow, the TRAC system may
reduce power from the engine to the wheels. Pressing
to turn
the system off may make it easier for you to rock the vehicle in order
to free it.
To turn the TRAC system off,
quickly press and release .
The “TRAC OFF” indicator light
will come on.
Press
again to turn the sys-
tem back on.
■ Turning off both TR AC and VSC systems

for more than 3
seconds while the vehicle is stopped.
The “TRAC OFF” indicator light and VSC OFF indicator light will come on.
Press again to turn the systems back on.

■Sounds and vibrations caused by the ABS, brake assist, TRAC and
VSC systems
●A sound may be heard from the engine compartment when the brake
pedal is depressed repeatedly, when the engine is started or just after the
vehicle begins to move. This sound does not indicate that a malfunction
has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
●When the engine switch is turned to the “LOCK” position (vehicles with-
out a smart key system) or the “ENGINE START STOP” switch is turned
off (vehicles with a smart key system)
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling
will not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the engine
off. The EPS system should return to normal within 10 minutes.
