3284-5. Using the driving support systems
HIGHLANDER_HV_U (OM48F12U)
◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆Enhanced VSC (Enhanced Ve hicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery
road surfaces by controllin g steering performance.
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake
pressure for individual wheels and reducing driving torque when
trailer sway is detected.
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
Driving assist systems
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when start-
ing on an uphill
◆EPS (Electric Power Steering)
Employs an electric motor to redu ce the amount of effort needed to
turn the steering wheel
◆VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, TRAC, VSC,
hill-start assist control, and EPS systems
Helps to maintain vehicle stab ility when swerving on slippery road
surfaces by controlling the br akes and hybrid system output

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

Remove the cover.
WARNING
■Items unsuitable for the open tray
Observe the following precautions when putting items in the open tray. Fail-
ure to do so may cause items to be thrown out of the tray in the event of
sudden braking or steering. In these cases, the items may interfere with
pedal operation or cause driver distraction, resulting in an accident.
● Do not store items in the tray that can easily shift or roll out.
● Do not stack items in the tray higher than the tray’s edge.
● Do not put items in the tray that may protrude over the tray’s edge.

When trouble arises
HIGHLANDER_HV_U (OM48F12U)
Steadily step on the brake pedal with both feet and firmly depress it.
Do not pump the brake pedal repeatedly as this will increase the effort
required to slow the vehicle.
Shift the shift lever to N.
If the shift lever is shifted to N
After slowing down, stop the vehicle in a safe place by the road.
Stop the hybrid system.
If the shift lever cannot be shifted to N
Keep depressing the brake pedal with both feet to reduce vehicle
speed as much as possible.
To stop the hybrid system,
press and hold the power
switch for 2 consecutive sec-
onds or more, or press it briefly
3 times or more in succession.
Stop the vehicle in a safe place by the road.
If your vehicle has to be stopped in an
emergency
Only in an emergency, such as if it becomes impossible to stop
the vehicle in the normal way, st op the vehicle using the follow-
ing procedure:

NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type
truck
● Do not tow the vehicle from the rear when the power switch is off.
The steering lock mechanism is not strong enough to hold the front wheels
straight.
● When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.
■ To prevent damage to the vehicle wh en towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
■ Recreational towing (beh ind motor home, etc.)
Never dinghy tow your vehicle to prevent
causing serious damage to the hybrid
transmission and AWD system.
