WARNING
QTrailer Sway Control precaution
The Trailer Sway Control system is
not able to reduce trailer sway in all situations. Depending on many fac-tors such as the conditions of the
vehicle, trailer, road surface and driv- ing environment, the Trailer Sway Control system may not be effective.
Refer to your trailer owner’s manual for information on how to tow your trailer properly.
QIf trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
OFirmly grip the steering wheel.
Steer straight ahead. Do not try to control trailer swaying by turning the steering wheel.
OBegin releasing the accelerator pedal immediately but very gradu-
ally to reduce speed. Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction
with the steering or brakes, your vehi-
cle and trailer should stabilize.
( P.264)
QSecondary Collision Brake (if
equipped)
Do not rely solely upon the Secondary Collision Brake. This system is
designed to help reduce the possibil- ity of further damage due to a second-ary collision, however, that effect
changes according to various condi- tions. Overly relying on the system may result in death or serious injury.

valves and transmitters.

4025-6. Driving tips
cautions to ensure your driving
enjoyment and to help prevent the
closure of areas to off-road vehi-
cles:
 Drive your vehicle only in areas
where off-road vehicles are per-
mitted to travel.
 Respect private property. Get
owner’s permission before enter-
ing private property.
 Do not enter areas that are
closed. Honor gates, barriers
and signs that restrict travel.
 Stay on established roads. When
conditions are wet, driving tech-
niques should be changed or
travel delayed to prevent dam-
age to roads.
WARNING
QOff-road driving precautions
Always observe the following precau- tions to minimize the risk of death, serious injury or damage to your vehi-
cle:
ODrive carefully when off the road. Do not take unnecessary risks by
driving in dangerous places.
ODo not grip the steering wheel
spokes when driving off-road. A bad bump could jerk the wheel and injure your hands. Keep both hands
and especially your thumbs on the outside of the rim.
OAlways check your brakes for effec-tiveness immediately after driving in sand, mud, water or snow.
OAfter driving through tall grass, mud, rock, sand, rivers, etc., check that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or trapped on the underbody. Clear off any such matter from the
underbody. If the vehicle is used with these materials trapped or adhering to the underbody, a break-
down or fire could occur.
OWhen driving off-road or in rugged
terrain, do not drive at excessive speeds, jump, make sharp turns, strike objects, etc. This may cause
loss of control or vehicle rollover causing death or serious injury. You are also risking expensive damage
to your vehicle’s suspension and chassis.
NOTICE
QTo prevent the water damage
Take all necessary safety measures to ensure that water damage to the hybrid battery (traction battery),
hybrid system or other components does not occur.
OWater entering the engine compart-
ment may cause severe damage to the hybrid system.
OWater entering the hybrid transmis-sion will cause deterioration in transmission quality. The malfunc-
tion indicator may come on, and the vehicle may not be drivable.
OWater can wash the grease from wheel bearings, causing rusting and premature failure, and may
also enter the hybrid transaxle case, reducing the gear oil’s lubri-cating qualities.
