WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is stopped
●Do not race the engine.
If the shift lever is in any position other than P or N, the vehicle may accelerate sud-
denly and unexpectedly, causing an accident.
●In order to prevent accidents due to the vehicle rolling away, always keep depressing
the brake pedal while the engine is running, and apply the parking brake as neces-
sary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, alwa ys depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine.
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 combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, sp ray cans, or soft drink cans in the vehicle
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 cau se the plastic lenses and plastic mate-
rial 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 circui t in the vehicle’s electrical components.
●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 windsh ield or windows. Do not place containers
such as air fresheners on th e instrument panel or dashboard. Adhesive discs or con-
tainers may act as lenses, ca using a fire in the vehicle.
●Do not leave a door or window open if th e curved glass is coated with a metallized
film such as a silver-colored one. Reflecte d sunlight may cause the glass to act as a
lens, causing a fire.
●Always apply the parking brake, shift the shift lever to P, stop the engine and lock the
vehicle.
Do not leave the vehicle unattend ed while the engine is running.
If the vehicle is parked with the shift leve r in P but the parking brake is not set, the
vehicle may start to move, possibly leading to an accident.
●Do not touch the exhaust pipes while the engine is running or immediately after turn-
ing the engine off.
Doing so may cause burns.

WARNING
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed properly, may block the
driver’s vision, or may result in items hittin g the driver or passengers, possibly causing
an accident.
●Stow cargo and luggage in the luggage compartment whenever possible.
●Do not stack cargo and luggage in the luggage compartment higher than the seat-
backs.
●When you fold down the rear seats, long items should not be placed directly behind
the front seats.
●Never allow anyone to ride in the luggage compartment. It is not designed for pas-
sengers. They should ride in their seats with their seat belts properly fastened.
●Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or re ar seats (when stacking items)
•On the luggage cover
• On the instrument panel
•On the dashboard
●Secure all items in the occupant compartment.
■Capacity and distribution
●Do not exceed the maximum axle weight rating 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 deterioration
of steering or braking control whic h may cause death or serious injury.
■Roof luggage carrier precautions
Observe the following precautions:
●Place the cargo so that its weight is distributed evenly between the front and rear
axles.
●If loading long or wide cargo, never exceed the vehicle overall length or width.
( P. 698)
●Before driving, make sure the cargo is secu rely fastened on the roof luggage carrier.
●Loading cargo on the roof luggage carrier will make the center of gravity of the vehi-
cle higher. Avoid high speeds, sudden star ts, sharp turns, sudden braking or abrupt
maneuvers, otherwise it may re sult in loss of control or vehicle rollover due to failure
to operate this vehicle correctly and result in death or serious injury.
●If driving for a long distance, on rough road s, or at high speeds, stop the vehicle now
and then during the trip to make sure the cargo remains in its place.
●Do not exceed 165 lb. (75 kg) cargo weight on the roof luggage carrier.
NOTICE
■When loading cargo (vehicles with a moon roof or panoramic moon roof)
Be careful not to scratch the surface of the moon roof or panoramic moon roof.

●To maintain engine braking efficien cy and charging system performance
when using engine braking, do not put th e transmission in D. If in the M or S
mode, the transmission shift range po sition must be in 6 or lower. (P. 240)
●Instability happens more fr equently when descending steep or long downhill
grades. Before descending, slow down and downshift. Do not make sudden
downshifts while descending st eep or long downhill grades.
●Avoid holding the brake pedal down too long or applying the brakes too fre-
quently. This could cause the brakes to overheat and result in reduced braking
efficiency.
●Due to the added load of the trailer, yo ur vehicle’s engine may overheat on hot
days (at temperatures over 85 F [30 C]) when driving up a long or steep
grade. If the engine coolant temperat ure gauge indicates overheating, imme-
diately turn off the air conditioning (if in use), pull your vehicle off the road and
stop in a safe spot. ( P. 692)
●Always place wheel blocks under both the vehicle’s and the trailer’s wheels
when parking. Put the transmission in P and apply the parking brake. Avoid
parking on a slope, but if unavoidable, do so only after performing the follow-
ing:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and trailer’s
wheels.
When the wheel blocks are in place, release the brakes slowly until the
blocks absorb the load.
Shift into P and apply the parking brake.
Turn off the engine.
●When restarting afte r parking on a slope:
With the transmission in P, start the en gine. Be sure to keep the brake pedal
depressed.
Shift into a forward gear. If reversing, shift into R.
If the parking brake is in manual mode, release the parking brake.
( P. 248)
Release the brake pedal, and slowly pull or back away from the wheel
blocks. Stop and apply the brakes.
Have someone retrieve the blocks.

■Operation of the engine switch
●If the switch is not pressed shortly and firmly, the engine switch mode may not change
or the engine may not start.
●If attempting to restart the engine immediately after turning the engine switch off, the
engine may not start in some cases. After turning the engine switch off, please wait a

WARNING
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the accelerator
pedal while starting the engine under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the doors until
the vehicle reaches a safe and complete stop. Activation of the steering lock in this cir-
cumstance may lead to an accident, re sulting in death or serious injury.
■Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle, press and hold
the engine switch for more than 2 seconds, or press it briefly 3 times or more in succes-
sion. ( P. 645)
However, do not touch the engi ne switch while driving except in an emergency. Turning
the engine off while driving will not cause lo ss of steering or braking control, but the
power assist to these systems will be lost. Th is will make it more difficult to steer and
brake, so you should pull over and stop the vehicle as soon as it is safe to do so.
