When driving
The multi-information display operate when
Vehicles without a smart entry & start system
The engine switch is in the “ON” position.
Vehicles with a smart entry & start system
The “ENGINE START STOP” switch is in IGNITION ON mode.
CAUTION
The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the driver's shifting and the new shift
position number appearing on the display. In this case, wait until the display
changes and take care not to downshift again, causing rapid and excessive
engine braking and possibly an accident resulting in death or serious injury.

or repairer, or another duly qualified and equipped professional
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features P. 447)
NOTICE
To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not run-
ning.
Turn off the engine with the light switch

If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
windshield washer fluid reservoir.
CAUTION
Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
Washer/wiper dual opera-
tion
The wipers will automatically
operate a couple of times after
the washer squirts.
Vehicles with discharge head-
lights: When the headlights are
on and the lever is pulled and
held, the headlight cleaners
will operate once.

2-4. Using other driving systems

When driving
Driving assist systems
When the TRC/VSC systems are operating
The slip indicator light will flash
while the TRC (brake LSD func-
tion)/VSC systems are operat-
ing.
To help enhance driving safety and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily 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
TRC (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 TRC system is also equipped with the brake LSD function.
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

228 2-4. Using other driving systems
Turning off both TRC and VSC systems
To turn the TRC and VSC systems off, press and hold for more than 3
seconds while the vehicle is stopped.
The “TRC OFF” indicator light and the VSC off indicator light will come on.
In this case, the brake LSD function remains on.
Press the button again to turn the systems back on.
Sounds and vibrations caused by the ABS, brake assist, TRC 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 TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automati-
cally reactivated in the following situations:
Vehicles without a smart entry & start system: When the engine switch is
turned to “LOCK” position
Vehicles with a smart entry & start system: When the “ENGINE START
STOP” switch is turned off
If only the TRC system is turned off, the TRC will turn on when vehicle
speed is more than approximately 50 km/h (31 mph).
If both the TRC and VSC systems are turned off, automatic reactivation
will not occur when vehicle speed increases.

229 2-4. Using other driving systems

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 “VSC SPORT” mode
Vehicles without a smart entry & start system
When the engine switch is turned to “LOCK” position after driving in “VSC
SPORT” mode, the mode is automatically deactivated.
Vehicles with a smart entry & start system
When the “ENGINE START STOP” switch is turned off after driving in “VSC
SPORT” mode, the mode is automatically deactivated.
CAUTION
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
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.

255 3-1. Using the air conditioning system and defogger
3
Interior features
Ventilation and air conditioning odors
To let fresh air in, set the air conditioning system to the outside air mode.
During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
Air conditioning filter
P. 328
CAUTION
To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
NOTICE
To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
