Hybrid system precautions
Take care when handling the hybrid system, as it contains a high
voltage system (about 650 V at maximum) as well as parts that
become extremely hot when the hybrid system is operating.
Obey the caution labels attached to the vehicle.

2224-1. Before driving
HIGHLANDER_HV_U (OM48F12U)
●Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a wider than normal turning radius.
● Slow down before making a turn, in cross winds, on wet or slippery
surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● To maintain engine braking effici ency and charging system perfor-
mance when using engine braking, do not put the transmission in
D. If in the S mode, the transmission shift range position must be in
4 or lower.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the brakes
too frequently. This could cause th e brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may over-
heat on hot days (at temperatures over 85 F [30C]) when driving
up a long or steep grade. If t he engine coolant temperature gauge
indicates overheating, immediately turn off the air conditioning (if in
use), pull your vehicle off the road and stop in a safe spot.
(  P. 525)

2404-2. Driving procedures
HIGHLANDER_HV_U (OM48F12U)
■Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. (P. 328) To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■ Automatic return to normal driving mode
If EV drive mode is selected, the driving mode will automatically return to nor-
mal mode when the hybrid system is turned off.
■ S mode
●When the shift range is 5 or lower, holding the shift lever toward “+” sets the
shift range to 6.
● To prevent the engine from over-revving, upshifting may automatically
occur.
■ When driving with cruise control or dynamic radar cruise control acti-
vated
Even when performing the following actions with the intent of enabling engine
braking, engine braking will not activate while driving in S mode and down-
shifting to 5 or 4 because cruise control or dynamic radar cruise control will
not be canceled. ( P. 266, 271)
■ If the shift lever cannot be shifted from P
P. 516
■ If S does not come on even afte r shifting the shift lever to S
This may indicate a malfunction in the hybrid transmission system. Have \
the
vehicle inspected by your Toyota dealer immediately.
(In this situation, the hybrid transmission will operate in the same as manner
as when the shift lever is in D.)
■ Downshift restriction warning buzzer
To help ensure safety and driving performance, downshifting operation may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever is operated. (The buzzer will sound twice.)

2904-5. Using the driving support systems
HIGHLANDER_HV_U (OM48F12U)
■Temporary cancelation of the LDA system functions
If any of the following occurs, the LDA system functions will be temporarily
canceled. The functions will resume after the necessary operating conditions
have returned.
● The turn signal lever is operated.
● The vehicle speed deviates from the operating range of the LDA system
functions.
● When the lane lines cannot be recognized while driving.
● When the lane departure warning function is activated.
The lane departure warning function will not operate again for a several sec-
onds after it has been activated, even if the vehicle leaves the lane again.
■ The lane departure warning
Depending on the audio system sound level or air conditioning fan noise
while the audio system or air conditioning system is in use, it may be difficult
to hear the warning sound.
■ After the vehicle has been parked in the sun
The LDA system may not be available and a warning message ( P. 478) will
be displayed for a while after driving has started. When the temperature in the
cabin decreases and the temperature around the camera sensor ( P. 286)
becomes suitable for its operation, the functions will begin to operate.
■ If there are lane markers on only one side of the vehicle
The lane departure warning will not operate for the side on which lane mark-
ers could not be recognized.

4-6. Driving tips
■Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (h eating/cooling) will be minimized, improving
the fuel economy. ( P. 328)
■Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of
Hybrid System Indicator within Eco area. ( P. 105)
■When braking the vehicle
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
■Delays
Repeated acceleration and decelerati on, as well as long waits at
traffic lights, will lead to bad fuel consumption. Check traffic reports
before leaving and avoid delay s as much as possible. When
encountering a delay, gently release the brake pedal to allow the
vehicle to move forward slightly while avoiding overuse of the
accelerator pedal. Doing so can help control excessive gasoline
consumption.
■Highway driving
Control your speed and keep at a constant speed. Also, before
stopping at a toll booth or similar, allow plenty of time to release the
accelerator and gently apply the br akes. A greater amount of elec-
trical energy can be retained when slowing down.
Hybrid vehicle driving tips
For economical and ecological driv ing, pay attention to the fol-
lowing points:

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.
