Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differ ential or wheel bearing), Toyota rec-
ommends that you do not tow a trailer until the vehicle has been driven for
over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start
towing. However, for the next 500 miles (800 km), drive the vehicle at a speed
of less than 50 mph (80 km/h) when towing a trailer, and avoid full throttle
acceleration.
■ 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 approximately
600 miles (1000 km) of trailer towing.
■ If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
• Begin releasing the accelerator pedal immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize.
● After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred
is beyond the limit of your particular v ehicle-trailer combination. Drive at a
lower speed to prevent instability. Remember that swaying of the towing vehi-
cle-trailer increases as speed increases.

3184-6. Driving tips
HIGHLANDER_HV_U (OM48F12U)■
Air conditioning
Use the air conditioning only when
necessary. Doing so can help
control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce the burden on the air conditioner and
reduce fuel cons umption as well.
In winter: Because the gasoline eng ine will not automatically cut out
until the gasoline engine and the in terior of the vehicle are warm, it
will consume fuel. Also, fuel consumption can be improved by
avoiding overuse of the heater.
■Checking tire inflation pressure
Make sure to check the tire infl ation pressure frequently. Improper
tire inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to poor fuel co nsumption. Use a tire that is
appropriate for the season.
■Luggage
Carrying heavy luggage can lead to poor fuel consumption. Avoid
carrying unnecessary luggage. Insta lling a large roof rack can also
cause poor fuel consumption.
■Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover, fre-
quently driving short distances will cause the engine to repeatedly
warm up, which can lead to poor fuel consumption.

NOTICE
■To prevent 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 riverbed for firmness. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
●Sand and mud that has accumulated 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”.

Adding engine oil
If the oil level is below or near
the low level mark, add engine
oil of the same type as that
already in the engine.
Make sure to check the oil type and prepare the items needed
before adding oil.
Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.
■ Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following
situations, oil consumption may increase, and engine oil may need to be
refilled in between oil maintenance intervals.
●When the engine is new, for example directly after purchasing the vehicle or
after replacing the engine
● If low quality oil or oil of an inappropriate viscosity is used
● When driving at high engine speeds or with a heavy load, when towing, or
when driving while accelerating or decelerating frequently
● When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
