NOTICE
■To prevent the water damage
Take all necessary safety measures to ensure that water damage to the
hybrid 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 transaxle will cause deterioration in transmission
quality. The malfunction indicator may come on, and the vehicle may not
be drivable.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the transaxle case, reducing the gear
oil’s lubricating 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 river bed for firmness. Drive
slowly and avoid deep water.
■ Inspection after o ff-road driving
● Sand and mud that has accumulate d in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.

Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. (See “Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km) of trailer towing.
CAUTION
■Trailer towing precautions
●Follow all the instructions described in this section. Failure to do so could
cause an accident resulting in death or serious injury.
● Exceeding the towing capacity, GVWR or GAWR can cause an accident
resulting in death or serious personal injuries.
■ To avoid accident or injury
●Do not exceed 45 mph (72 km/h) or the posted towing speed limit, which-
ever is lower. As instability (swaying) of the towing vehicle-trailer combina-
tion increases as speed increases, exceeding 45 mph (72 km/h) may
cause loss of control.
● Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue load capacities.
● Never load more weight in the back than in the front of the trailer. About
60% of the load should be in the front half of the trailer, and the remaining
40% in the rear.
● Do not use cruise control when you are towing.
● Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts.
● Avoid holding the brake pedal down too long or applying the brakes too
frequently. This could cause the brakes to overheat and result in reduced
braking efficiency.
● Do not tow the vehicle with the compact spare tire installed.

Maintenance requirements
■Repair and replacement
It is recommended that genuine Toyota parts be used for repair to ensure
performance of each system. If non-Toyota parts are used in replacement or
if a repair shop other than a Toyota dealer performs repairs, confirm the war-
ranty coverage.
To ensure safe and economical driv ing, day-to-day care and regular
maintenance is essential. It is the owner’s responsibility to perform
regular checks. Toyota recommends the following maintenance.
■ General maintenance
General maintenance should be performed on a daily basis.
This can be done by yourself or by a Toyota dealer.
■ Scheduled maintenance
Scheduled maintenance should be performed at specified inter-
vals according to the maintenance schedule.
For details about maintenance items and schedules, refer to the
“Scheduled Maintenance Guide” or “Owner’s Manual Supplement”.
■ Do-it-yourself maintenance
You can perform some maintenance procedures yourself.
Please be aware that do-it-yourself maintenance may affect war-
ranty coverage.
The use of Toyota Repair Manuals is recommended.
For details about warranty coverage, see the separate “Owner’s
Warranty Information Booklet” or “Owner’s Manual Supplement”.
