When driving
CAUTION
■When the vehicle is stopped
●Do not race the engine.
• If the vehicle is in any gear other than Neutral the vehicle may accelerate sud-denly and unexpectedly, causing an accident.
• Running the engine at high speed while the vehicle is stopped may cause the exhaust system to overheat, which could result in a fire if flammable material is
nearby.
• Racing the engine may emit loud noise, and possibly cause a nuisance, espe- cially after just starting the engine. This is because the structure of the exhaust
pipes cause the sound emitted from the exhaust to be louder than usual for
approximately 1 minute after the engine is started.
●Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do no t enter the vehicle interior.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of
the vehicle, and may also cause a short circuit in the vehicle's electrical com-
ponents.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such
as the glove box or on the floor, it may be lit accidentally when luggage is loaded
or the seat is adjusted, causing a fire.
●Do not attach adhesive discs to the wind shield or windows. Do not place contain-
ers such as air fresheners on the instru ment panel or dashboard. Adhesive discs
or containers may act as lenses, causing a fire in the vehicle.

2-3. Operating the lights and windshield wipers
2
When driving
■The windshield wipers and wa sher can be operated when
The ignition switch is in the “ON” position.
■Effects of vehicle speed on wiper operation
The time until the drip prevention wiper sweep occurs is changed depending on
vehicle speed.
When low speed wiper operation is selected , wiper operation will be switched from
low speed to intermittent wiper operatio n only when the vehicle is stationary.
(However, when the intermittent wiper interv al adjuster is adjusted to the highest
level, the mode will not switch.)
■Wiper reverse motion
If snow or similar substances build up around the windshield and prevent the wiper
from moving smoothly, the wiper may reverse direction before the end of its stroke
in order to secure driver vi sibility and to protect the system. This is normal and does
not indicate a malfunction.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
■Lifting the wiper
Activate the wiper and turn the ignition
switch to the “LOCK” position when the
wiper approaches the upper reverse position.
The wiper will stop moving.
Lift and hold the main and sub blades. The blades will not remain in the up posi-
tion if released.STEP1

2-5.Driving information
Cargo and luggage
Take notice of the following information about storage precautions, cargo
capacity and load:
●Stow cargo and luggage in the luggage compartment whenever possi-
ble.
● Be sure all items are secured in place.
● To maintain vehicle balance while driving, position luggage evenly
within the luggage compartment.
● For better fuel economy, do not carry unnecessary weight.
Capacity and distribution
Cargo capacity depends on the to tal weight of the occupants.
(Cargo capacity) = (Total load capa city) — (Total weight of occupants)
Steps for Determining Correct Load Limit 
(1) Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s placard.
(2) Determine the combined weight of th e driver and passengers that will
be riding in your vehicle.
(3)Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
(4)The resulting figure equals the av ailable amount of cargo and luggage
load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will be
five 150 lb passengers in your vehicle, the amount of available cargo
and luggage load capacity is 650 lbs. (1400  750 (5150) = 650
lbs.)
(5)Determine the combined weight of luggage and cargo being loaded
on the vehicle. That weight may no t safely exceed the available cargo
and luggage load capacity calculated in Step 4.

2-5. Driving information
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.
Failure to do so may result in death or serious injury.
●Stow cargo and luggage in the lugga ge compartment whenever possible.
●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 passenger, caus-
ing an accident:
• At the feet of the driver
• On the passenger seat (when stacking items)
• On the package tray
• On the instrument panel
•On the dashboard
●Secure all items in the occupant compartment, as they may shift and injure some-
one during sudden braking, sudden swerving or an accident.
●Never allow anyone to ride in the luggage compartment. It is not designed for
passengers. The passenger should ride in th e seat with the seat belt properly fas-
tened. Otherwise, the passenger is much more likely to suffer death or serious
bodily injury, in the event of sudden br aking, sudden swerving or an accident.
■Capacity and distribution
●Do not exceed the maximum axle weight ra ting or the total vehicle weight rating.
●Even if the total load of occupant’s weight and the cargo load is less than the total
load capacity, do not apply the load unevenly. Improper loading may cause dete-
rioration of steering or braking control which may cause death or serious injury.
