2-4. Using other driving systems
Driving assist systems
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.
VSC+ (Vehicle Stability Control+)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.
TRC (Traction Control)
Maintains drive power and prevents the front wheels from spinning
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.

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 smart entry & start system
When the engine switch is turned off
If only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are turned off, automatic reactivation
will not occur when vehicle speed increases.
Vehicles with 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 increases
If both the TRC and VSC systems are turned off, automatic reactivation
will not occur when vehicle speed increases.
Sounds and vibrations caused by the ABS, VSC, TRC and brake assist
systems
A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate 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.

Cargo and luggage
CAUTION
Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compartment.
Receptacles containing gasoline
Aerosol cans
Storage precautions
Observe the following precautions.
Failing to do so may result in death or serious injury.
Do not place cargo or luggage in or on the following locations as the item
may get under the brake or accelerator pedal and prevent the pedals from
being depressed properly, block the driver’s vision, or hit the driver or pas-
sengers, causing an accident.
• Driver’s feet
• Front passenger or rear seats (when stacking items)
• Instrument panel
• Dashboard
• Auxiliary box or tray that has no lid
Do not stack anything in the luggage compartment higher than the seat-
backs.
Such items may be thrown about and possibly injure people in the vehicle
during sudden braking or in an accident.
Take notice of the following information about storage precautions,
cargo capacity and load.
Stow cargo and luggage in the luggage compartment whenever
possible.
Be sure all items are secured in place.
Be careful to keep the vehicle level. Placing the weight as far for-
ward as possible helps maintain vehicle balance.
For better fuel economy, do not carry unnecessary weight.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
Pre-winter preparations
Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.
Before driving the vehicle
Perform the following according to the driving conditions.
Do not try to forcibly open a window, scrape an outside rear
view mirror surface or move a wiper or outside rear view mir-
ror that is frozen. Pour warm water over the frozen area to
melt the ice. Wipe away the water immediately to prevent it
from freezing.
To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
Remove any ice that has accumulated on the vehicle chassis.
Periodically check for and remove any excess ice or snow
that may have accumulated in the wheel well or on the
brakes.

When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed suit-
able to road conditions.
When parking the vehicle
Park the vehicle and move the shift lever to P (Multidrive) or to 1
or R (manual transmission) without setting the parking brake
and then chock the tires. The parking brake may freeze up, pre-
venting it from being released. If necessary, block the wheels to
prevent inadvertent sliding or creeping.

Stop the vehicle on level ground, set the parking brake and shift the shift
lever to P (Multidrive) or 1 (manual transmission).
Be careful not to get your hands or feet pinched in the seat.
After returning the seat cushion to the original position
Make sure the bottom cushion is securely locked.
Caution while driving
Do not drive with the seat cushion raised.
Do not place anything that may roll, or is larger than the available space
