HIGHLANDER_U (OM48E98U)■
If the “DAC” switch is turned off during operation of the downhill assist
control system
The downhill assist control system gradually ceases operation. The downhill
assist control system indicator will flash during the canceling operation, and
then go off when the system is fully off.
■ Downhill assist contro l system operation sound
● A sound may be heard from the engine compartment during operation of the
downhill assist control system. This sound does not indicate a malfunction.
● If the accelerator or brake pedal is depressed during operation of the down-
hill assist control system, a sound caused by the release of system opera-
tion may be heard, or you may feel the brake pedal push-back. This does
not indicate a malfunction.
■ When the downhill assist cont rol system operates continuously
The brake actuator may overheat. In that case, the downhill assist control
system will stop operating, a buzzer will sound and the downhill assist control
system indicator will start flashing. Refrain from using the system until the
downhill assist control system indicator stays on. (There is no problem with
continuing to drive normally.)
■ If the slip indicator comes on
It may indicate a malfunction in the system. Contact your Toyota dealer.
WARNING
■Conditions which may affect the downhill assist control system opera-
tion
● Do not rely too heavily on the downhill assist control system. On extremely
steep inclines, icy surfaces or muddy roads, the vehicle may slip and the
system may not be able to maintain the constant low vehicle speed of
about 3 mph (5 km/h), leading to an accident causing death or serious
injury.
● Do not shift the shift lever to R while driving forward, or to D while driving
backward. Doing so may cause the wheels to lock up, leading to an acci-
dent causing death or serious injury. In addition, excessive stress will be
applied to the automatic transmission, possibly resulting in damage.

In other situations
Even though all conceivable measures have been taken, the symptom sta-
tus does not change.
The cellular phone is not close enough to this system.
Bring the cellular phone closer to this system.
The cellular phone is the most likely cause of the symptom.
Turn the cellular phone off, remo ve and reinstall the battery pack,
and then restart the cellular phone.
Enable the cellular phone’s Bluetooth
® connection.
Stop the cellular phone’s security software and close all applica-
tions.
Before using an application installed on the cellular phone, care-
fully check its source and how its operation might affect this sys-
tem.

Press and hold the pro-
grammed HomeLink® button
(located inside the vehicle)
for 2 seconds and release it.
Repeat this sequence (press/
hold/release) up to 3 times to
complete programming.
If the garage door opener motor
activates when the HomeLink®
button is pressed, the garage
door opener motor recognizes
the HomeLink
® signal.
■
Enabling 2-way communication with a garage door (only avail-
able for compatible devices)
When enabled, 2-way communication allows you to check the sta-
tus of the opening and closing of the garage door through indicators
in your vehicle.
2-way communication is only available if the garage door opener
motor used is a compatible device. (To check device compatibility,
refer to the owner’s manual supplied with the garage door opener
motor.)
Press a programmed HomeLink
® button to operate a garage
door.
Within 1 minute of pressing the HomeLink
® button, after the
garage door operation has stopped, press the “learn” or “smart”
button on the garage door opener motor. Within 5 seconds of the
establishment of 2-way comm unication with the garage door
opener, both garage door operati on indicators in the vehicle will
flash rapidly (green).
■Reprogramming a single HomeLink® button
When the following procedure is pe rformed, buttons which already
have devices registered to them can be overwritten:
With one hand, press and hold the desired HomeLink
® button.
When the HomeLink
® indicator starts flashing, continue to hold
the HomeLink® button and perform “Programming HomeLink®”
from (it takes 20 seconds for the HomeLink® indicator to start
flashing).

Follow the procedure below to restart the engine after the system is
activated.
Vehicles without a smart key system
Turn the engine switch to the “ACC” or “LOCK” position.
Restart the engine.
Vehicles with a smart key system
Turn the engine switch to ACCESSORY mode or turn it off.
Restart the engine.
Fuel pump shut off system
To minimize the risk of fuel leakage when the engine stalls or
when an airbag inflates upon collision, the fuel pump shut off
system stops the supply of fuel to the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine.

WARNING
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a dif-
ferent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pre ssure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pressure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency and tire tread life, and may
affect the vehicle’s hand ling and stopping ability.
Please note that the TPMS (tire pres sure warning system) is not a sub-
stitute for proper ti re maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumina tion of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicator to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) malfunc-
tion indicator is combined with the lo w tire pressure telltale (tire pressure
warning light). When the system dete cts a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue up on subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tire pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installati on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
