When driving
CAUTION
■
When starting the hybrid system
Always start the hybrid system while sitting in the driver's seat. Do not
depress the accelerator while starting the hybrid system under any circum-
stances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution when driving
Do not turn the engine switch to the “LOCK” position while driving. If, in an
emergency, you must turn the hybrid system off while the vehicle is moving,
turn the key only to the “ACC” position.
NOTICE
■To prevent 12-volt battery discharge
Do not leave the key in the “ACC” or “ON” position for long periods without
the hybrid system on.
■ When starting the hybrid system
●Do not crank for more than 30 seconds at a time. This may overheat the
starter and wiring systems.
● Do not race a cold hybrid system.
● If the hybrid system becomes difficult to start or stalls frequently, have the
hybrid system checked immediately.

2-1. Driving procedures
EV-Drive Mode
■Situations in which EV-Drive Mode cannot be turned on
It may not be possible to turn EV-Drive Mode on in the following situations. If
it cannot be turned on, a buzzer will sound and a message will be shown on
the multi-information display.
●The temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high
speeds, etc.
● The temperature of the hybrid system is low.
The vehicle has been left in extremely low temperatures for a long period
of time etc.
● The gasoline engine is warming up.
● The hybrid battery (traction battery) is low.
The remaining battery level indicated in the “Energy Monitor” display is
level 3 or lower. ( P. 37)
● Vehicle speed is about 25 mph (40 km/h) or more.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
● The windshield defogger is in use.
In EV-Drive Mode the electric motor (traction motor), powered by the
hybrid battery (traction battery), is used to drive the vehicle.
On/off
When EV-Drive Mode is turned
on, the EV-Drive Mode indica-
tor will come on. Pressing the
switch when in EV-Drive Mode
will return to normal driving
(using the gasoline engine and
electric motor [traction motor]).

■
Automatic cancelation of EV-Drive Mode
When driving in EV-Drive Mode, the gasoline engine may automatically
restart in the following situations. When EV-Drive Mode is canceled, a
buzzer will sound and the EV-Drive Mode indicator will flash and go off.
●The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the “Energy Monitor” display is
level 2 or lower. ( P. 37)
● Vehicle speed becomes more than about 25 mph (40 km/h).
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
■ Possible driving distance when driving in EV-Drive Mode
Possible driving distance when driving in EV-Drive Mode is up to about 1/2
mile (1 km) if driven at a speed of about 25 mph (40 km/h) or less. (Possible
driving distance depends on the hybrid battery [traction battery] level and
driving conditions.)
■ Fuel economy
Highlander is designed to achieve the best possible fuel economy during
normal driving (using the gasoline engine and electric motor [traction
motor]). Driving in EV-Drive Mode more than necessary may lower fuel
economy.
CAUTION
■Caution while driving
When driving in EV-Drive Mode, pay special attention to the area around the
vehicle. Because there is no engine noise, pedestrians, people riding bicy-
cles or other people and vehicles in the area may not be aware of the vehicle
starting off or approaching them, so take extra care while driving.

192 2-1. Driving procedures
■When in heavy traffic
If the shift lever is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid putting the shift
lever in N for an extended period of time.
■ Eco drive mode
●When the accelerator pedal is depressed in Eco drive mode, it may take
more time to accelerate than usual. This is normal operation.
● Operation of the air conditioning system is controlled when in Eco drive
mode.

When drivingInstrument panel light control
The brightness of the instrument panel lights can be adjusted.
Brighter
Darker
When the headlight switch is
turned on, the brightness will
be reduced slightly unless the
control dial is turned fully up.
Odometer/Trip meterOdometer
Displays the total distance the vehicle has been driven.
Trip meter
Displays the distance the vehi cle has been driven since the
meter was last reset. Trip meters A and B can be used to
record and display different distances independently.
■ Power meter “CHARGE” zone
The “CHARGE” zone indicates regeneration* status. Regenerated energy
will be used to charge the battery.
*: When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical energy.
NOTICE
■To prevent damage to the engine and its components
The gasoline engine may be overheating if the temperature gauge is in the
red zone (H). In this case, immediately stop the vehicle in a safe place, and
check the engine after it has cooled completely. (
P. 562)

■Automatic light off system
Vehicles without smart key system
● When the headlights come on: The headlights and tail lights turn off 30
seconds after a door is opened and closed if the engine switch is turned
to the “ACC” or “LOCK” position. (The lights turn off immediately if
on the wireless remote control is pressed after all the doors are
locked.)
● When only the tail lights come on: The tail lights turn off automatically if
the engine switch is turned to the “ACC” or “LOCK” position and the
driver’s door is opened.
To turn the lights on again, turn the engine switch to the “ON” position, or
turn the light switch off and then back to or .

When driving
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 river bed for firmness. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
●Sand and mud that has accumulat ed 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”.
