fying them of the vehicle’s location (without needing to push t he “SOS” but-
ton) and an agent will attempt to speak with the occupants to a scertain the
level of emergency and assistance required. If the occupants are unable to
communicate, the agent automatically treats the call as an emer gency and
helps to dispatch the necessary emergency services. (→P. 76)
• An SRS airbag is deployed.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
● During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking contro l, but the
power assist to these systems will be lost. This will make it m ore difficult to
steer and brake, so you should pull over and stop the vehicle a s soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes im possible
to stop the vehicle in the normal way: P. 459
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 220)
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.
● Do not drive in excess of the speed limit. Even if the legal sp eed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicl e has high-
speed capability tires. Driving over 85 mph (140 km/h) may resu lt in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed c apability
tires or not before driving at such speeds.
● On vehicles with electronically modulated air suspension, if you drive
through deep water over about 20 in. (500 mm) in depth, put the vehicle
height in the “HI” mode using the height control switch and the n change to
manual mode by pushing the height control mode select switch. D rive your
vehicle at 18 mph (30 km/h) or less. Do not drive through water deeper
than about 28 in. (700 mm) even if the vehicle height is in “HI” mode.

2044-1. Before driving
SEQUOIA_OM_USA_OM0C021U_20MY
If a height control system is installed in your vehicle, you have to con-
nect and disconnect your trailer more carefully.
● Connecting
Set the height control of electronically modulated air suspensi on
system to “N” mode.
Turn off the engine, or set the electronically modulated air su spen-
sion system to manual mode. ( P. 310)
Connect the trailer.
Restart the engine.
Press the height control mode select switch to cancel the manua l
mode condition that was set on step .
Check that the “OFF” i ndicator turns off.
Set the height control of electronically modulated air suspensi on
system to “N” mode.
● Disconnecting
Set the height control of electronically modulated air suspensi on
system to “N” mode.
Set the electronically modulat ed air suspension system to manua l
mode.
Turn off the engine.
Set the supporting leg of the trailer on the ground and raise t he
hitch by 4 in. (100 mm).
Restart the engine.
Press the height control mode select switch to cancel the manua l
mode condition that was set on step .
Check that the “OFF” i ndicator turns off.
Wait until vehicle h eight is stabilized.
Make sure the hitch is disconnected. If the hitch does not disc on-
nect, raise the hitch higher and repeat steps through .
Move the vehicle forward in “LO” mode where the hitch does not touch
anything in “N” mode.
Set the height control of electronically modulated air suspensi on system to
“N” mode.

Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 527)
● Trailer tires are inflated according to the trailer manufacture r’s recommen-
dation.
● All trailer lights work as required by law.
● All lights work each time you connect them.
● The trailer ball is set at the proper height for the coupler on the trailer.
● The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for imprope r tongue weight,
overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors ap propriate for tow-
ing purposes.
● Depress “TOW/HAUL” button (if equipped)
■ AVS (adaptive variable suspension system) (if equipped)
The suspension can be switched for improvement in drivability. (P. 314)
■ Break-in schedule
If your vehicle is new or equipped with any new power train com ponents
(such as an engine, transmission, differential or wheel bearing ), Toyota rec-
ommends that you do not tow a trailer until the vehicle has bee n driven for
over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start
towing. However, for the next 500 miles (800 km), drive the veh icle at a speed
of less than 50 mph (80 km/h) when towing a trailer, and avoid full throttle
acceleration.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent m aintenance due
to the additional load. (See “Scheduled Maintenance Guide” or “ Owner’s
Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.

WARNING
■Trailer towing precautions
● To tow a trailer safely, use extreme care and drive the vehicle in accor-
dance with the trailer’s characteristics and operating conditio ns. Failure to
do so could cause an accident resulting in death or serious injury. Vehicle
stability and braking performance are affected by trailer stabi lity, brake set-
ting and performance, and the hitch. Your vehicle will handle d ifferently
when towing a trailer.
● Vehicles with electronically modulated air suspension: Set the vehicle
height to the “N” mode and turn off the rear height control air suspension
when you connect a trailer, otherwise the vehicle height may ch ange due
to the automatic leveling function, and you may catch part of your body in
the vehicle, resulting in an accident.
■ To avoid accident or injury
● Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR.
● If the gross trailer weight is over 2000 lb. (907 kg), a sway control device
with sufficient capacity is required.
● If the gross trailer weight is over 5000 lb. (2268 kg), a weigh t distributing
hitch with sufficient capacity is required.
● Adjust the tongue weight within the appropriate range. Place he avier loads
as close to the trailer axle as possible.
● Do not exceed 65 mph (104 km/h), the posted towing speed limit or the
speed limit for your trailer as set forth in your trailer owner ’s manual,
whichever is lowest. Slow down sufficiently before making a tur n, in cross
winds, on wet or slippery surface, etc. to help avoid an accident. If you
experience a vehicle-trailer instability from reducing a certai n speed, slow
down and make sure you keep your vehicle speed under the speed of
which you experience the instability.
● Do not make jerky, abrupt or sharp turns.

◆Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
◆Pre-collision brake assist
When the system determines that the possibility of a frontal colli-
sion is high, the system applies greater braking force in relat ion to
how strongly the brake pedal is depressed.
◆Pre-collision braking
When the system determines that the possibility of a frontal colli-
sion is high, the system warns the driver. If the system determ ines
that the possibility of a frontal collision is extremely high, the brakes
are automatically applied to hel p avoid the collision or reduce the
collision speed.
◆Suspension control
When the system determines that the possibility of a frontal colli-
sion is high, the Adaptive Variable Suspension System (
P. 3 1 4 )
will control the damping force of the shock absorbers to help m ain-
tain an appropriat e vehicle posture.
