Off-road driving precautions
Always observe the following precautions to minimize the risk of death or serious
injury or damage to your vehicle: ●
Drive carefully when off the road. Do not ta ke unnecessary risks by driving in danger-
ous places. ●
Do 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. ●
Always check your brakes for effectivenes s immediately after driving in sand, mud,
water or snow. ●
After driving through tall grass, mud, rock, sand, water, etc., check that there is no
grass, bush, paper, rags, stone, sand, et c. adhering or trap ped to the underbody.
Clear off any such matter from the underbody. If the vehicle is used with these materi-
als trapped or adhering to the underb ody, a breakdown or fire could occur.●
When driving off-road or in rugged terrai n, 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 vehi-
cle’s suspension and chassis.
NOTICE ■
To prevent 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. ●
Water entering the engine compartment may cause severe damage to the hybrid
system. Water entering the interior may cause the hybrid battery stowed under the
rear seats to short circuit. ●
Water entering the hybrid transmission and rear electric motor (traction motor) will
cause deterioration in transmission qualit y. The malfunction indicator may come on,
and the vehicle may not be drivable. ●
Water can wash the grease from wheel be arings, causing rusting and premature fail-
ure, and may also enter the hybrid transmission case, reducing the gear oil’s lubricat-
ing qualities. ■
When you drive through water
If driving through water, such as when crossing shallow streams, first check the depth of
the water and the bottom of the riverbed for firmness. Drive slowly and avoid deep
water. ■
Inspection after off-road driving ●
Sand and mud that has accumulated around brake discs may affect braking efficiency
and may damage brake system components. ●
Always perform a maintenance inspection after each day of off-road driving that has
taken you through rough terr ain, sand, mud, or water. For scheduled maintenance
information, refer to the “Warranty and Services Guide/Owner’s Manual Supple-
ment/Scheduled Maintenance”.

To prevent the windshield from fogging up ●
Do not use during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can cause
the outer surface of the windshield to fog up, blocking your vision.
■
To prevent burns ●
Do not touch the rear view mirror surfaces when the outside rear view mirror defog-
gers are on. ●
Do not touch the glass at lower part of the wi ndshield or to the si de of the front pillars

To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the hybrid sys-
tem is off. ●
Do not place anything on the instrument
panel which may cover th e air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.
In order to detect fog on the windshield, a sen-
sor which monitors the temperature of the
windshield, the surround humidity, etc. is
installed. (  P. 4 3 8 )
Follow these points to avoid damaging the sen-
sor: ●
Do not disassemble the sensor ●
Do not spray the glass cleaner on the sensor
or subject it to strong impacts ●
