When driving ■ 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 ju st 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 system s are
operating. None of these indicates that a malfunction has occur red.
• 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 activa ted.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring so und) 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 reactivated in the following situations:
● Vehicles without a smart key system: When the engine switch is turned to
“LOCK” position
● Vehicles with a smart key system: When the “ENGINE START STOP”
switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed is more than approximately 31 mph (50 km/h).
If both the TRAC and VSC systems are turned off, automatic reac tivation
will not occur when vehicle speed increases.

2502-4. Using other driving systems
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the s ystem from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result. Should thi s occur,
refrain from excessive steering input or stop the vehicle and t urn the engine
off. The EPS system should return to normal after a little whil e.
■ Automatic deactivatio n of “TRACK” mode
Vehicles without a smart key system
When the engine switch is turned to “LOCK” position after drivi ng in
“TRACK” mode, the mode is automatically deactivated.
Vehicles with a smart key system
When the “ENGINE START STOP” switch is turned off after driving in
“TRACK” mode, the mode is automatically deactivated.
WARNING■ The ABS does not operate effectively when
● Tires with inadequate gripping ability are used (such as excess ively worn
tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or s lick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping dista nce. Always
maintain a safe distance from the vehicle in front of you in th e following situ-
ations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces

Hill-start assist control Hill-start assist control helps to maintain braking force to as sist
starting off forward while facing uphill or starting off backwa rd while
facing downhill. As hill-start assist control is initially disa bled,
enable the system to make it operable. The enabled/disabled set ting
will be maintained the next time the engine is started.
The hill-start assist control ON
indicator will be illuminated
