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
■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.
The TRAC system is also equipped with the brake LSD function.
■Hill-start assist control

P. 191
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

When driving
When the TRAC/VSC systems are operating
The slip indicator light will flash
while the TRAC (brake LSD
function)/VSC systems are oper-
ating.
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.
In this case, the brake LSD function remains on. To turn the TRAC system off,
quickly press and release the
button.
The “TRAC OFF” indicator light
will come on.
Press the button again to turn the
system back on.

186 2-4. Using other driving systems
“TRACK” modeYour vehicle is equipped with two types of control modes to accom-
modate various driving prefer ences. The control modes can be
selected with the “TRACK” switch. Normal mode allows secure and
smooth normal driving. When t he switch is pressed and held for 1
second or more, “TRACK” mode is activated. Control characteristics
such as the VSC and TRAC are adjusted to afford maneuverability
closer to what a driver may desire, while a sense of security is
retained.
“TRACK” mode/Normal mode
The “TRACK” indicator and VSC
off indicator come on when in
“TRACK” mode.
To change back to normal mode
while in “TRACK” mode, press
or the “TRACK” switch.
Turning off both TRAC and VSC systemsTo turn the TRAC and VSC systems off, press and hold for
more than 3 seconds while the vehicle is stopped.
The “TRAC OFF” indicator light and the VSC off indicator light will
come on.
However, on vehicles with an aut omatic transmission, the brake LSD
function will remain on.
Press the button again to tu rn the systems back on.

When driving
■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 after a little while.
■ Automatic deactivation of “TRACK” mode
When the engine switch is turned to “LOCK” position 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 excessively worn
tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick 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 distance. Always
maintain a safe distance from the vehicle in front of you in the 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
■ TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ When the VSC and/or brake LSD function is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.

336 5-2. Steps to take in an emergency
WARNING
■When using the compact spare tire
●Remember that your compact spare tire is specifically designed for
use with your vehicle. Do not use your compact spare tire on another
vehicle.
●Do not use two compact spare tires simultaneously.
●Replace the compact spare tire with a standard tire as soon as possi-
ble.
●Avoid sudden acceleration, abrupt steering, sudden braking and shift-
ing operations that cause sudden engine braking.
●Install the compact spare tire on a front wheel.
■When storing the compact spare tire
Be careful not to catch fingers or other body parts between the compact
spare tire and the body of the vehicle.
■Speed limit when using the compact spare tire
Do not drive at speeds in excess of 50 mph (80 km/h) when a compact
spare tire is installed on the vehicle.
The compact spare tire is not designed for driving at high speeds. Failing
to observe this precaution may lead to an accident causing death or seri-
ous injury.
■When the spare tire is attached
The vehicle speed may not be correctly detected, and the following sys-
tems may not operate correctly:
●ABS & brake assist
●VSC
●TRAC
●EPS
●Cruise control
●LSD
