When the shift lever is in the S position, the shift lever can be oper-
ated as follows:For upshifting
For downshifting
The initial shift range in S mode is set automatically to 5 or 4 accord-
ing to vehicle speed.
■Shift ranges and their functions
● You can choose from 6 levels of engine braking force.
● A lower shift range will provide greater engine braking force than
a higher shift range, and the engine speed will also increase.

■Operation of the air conditio ning 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. 434) 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 dynamic radar cruise control activated
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 dynamic radar cruise control will not be canceled.
(→P. 292)
■ Shift lock system
The shift lock system is a system to prevent accidental operation of the shift
lever in starting.
The shift lever can be shifted from P only when the power switch is in ON
mode and the brake pedal is being depressed.

WARNING
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to set the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal
when the shift lock override button is pressed and the shift lever is shifted
out of P, the vehicle may suddenly start, possibly leading to an accident
resulting in death or serious injury.
NOTICE
■Hybrid battery (traction battery) charge precaution
If the shift lever is in N, the hybrid battery (traction battery) will not be
charged even when the engine is running. Therefore, if the vehicle is left
with the shift lever in N for a long period of time, the hybrid battery (traction
battery) will discharge, and this may result in the vehicle not being able to
start.

ECB operation sound
ECB operating sound may be heard in the following cases, but it does not
indicate that a malfunction has occurred.
●Operating sound heard from the engine compartment when the brake pedal
is operated.
● Motor sound of the brake system heard from the front part of the vehicle
when the driver’s door is opened.
● Operating sound heard from the engine compartment when one or two min-
utes passed after the stop of the hybrid system.
■ EPS operating sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the power switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the hybrid system
off. The EPS system should return to normal within 10 minutes.
WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces

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. 434)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of
Hybrid System Indicator within Eco area. ( →P. 105)
◆Shift lever operation
Shift the shift lever to D when stopped at a traffic light, or driving in
heavy traffic, etc. Shift the shift lever to P when parking. When
using the N, there is no positive effect on fuel consumption. In the
N, the gasoline engine operates but electricity cannot be gener-
ated. Also, when using the air cond itioning system, etc., the hybrid
battery (traction batter y) power is consumed.
◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual accelerati on and deceleration will make
more effective use of the electric motor (traction motor) without
having to use gasoline engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
Hybrid vehicle driving tips
For economical and ecological driv ing, pay attention to the fol-
lowing points:

3364-6. Driving tips
HIGHLANDER_HV_U (OM48F12U)
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper
tire inflation pressure can cause poor fuel economy.
Also, as snow tires can cause larg e amounts of friction, their use on
dry roads can lead to poor fuel economy. Use tires that are appro-
priate for the season.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.
◆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 wi ll cause the engine to repeatedly
warm up, which can lead to excess fuel consumption.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
● Use snow tires on all, not just some wheels.
■ Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
● Do not use LDA (Lane Departure Alert with steering control) system.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Toyota dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
