WARNING
■The electronically modulated air suspension must be turned off in the
following circumstances:
Otherwise, the automatic leveling function may cause the vehicle’s height to
change, and you may catch part of your body in the vehicle, resulting in an
unexpected accident:
● When driving through water such as shallow streams (Put the veh icle
height in “HI” mode and turn off the electronically modulated a ir suspen-
sion. Drive at 18 mph [30 km/h] or slower.)
● When jacking up the vehicle, installing tire chains or tying th e vehicle with
chains/wires for transportation via flat bed truck (Turn the system to the
manual mode and stop the engine.)
● When the vehicle must be towed (Put the vehicle height in “N” mode and
turn the system to the manual mode.)
● When the vehicle gets stuck (Turn the system to the manual mode .)
● When disconnecting a trailer (Put the vehicle height in “N” mod e and turn
the system to the manual mode.)
■ Selecting the correct height mode
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the vehicle, as w ell as dan-
gerous handling characteristics, which may lead to fatal or inj ury accidents.
● Before you lower the vehicle’s height, check under the vehicle to make
sure that no one is there.
● “HI” mode should only be used when driving on rough roads, for example
when driving off-road.
Because the vehicle’s center of gravity will become higher when in the
mode, the vehicle may become unstable when turning abruptly, resulting
in an accident.
● Do not select “HI” mode when you load cargo on the roof luggage carrier.
Because the vehicle’s center of gravity will become higher when in the
mode, the vehicle may become unstable when turning abruptly, resulting
in an accident.

Four-wheel drive system
“2WD” (high speed position, two-wheel drive)
Use this for normal driving on dry hard-surfaced roads. This position gives
greater economy, quietest ride and least wear.
“4H” (high speed position, four-wheel drive)
Use this for driving only on tracks that permit the tires slide , like off-road,
icy or snow-covered roads. This position provides greater tract ion than
two-wheel drive.
The “4HI” indicator will come on.
“4L” (low speed position, four-wheel drive)
Use this for maximum power and traction. Use “4L” for climbing or
descending steep hills, off-road driving, and hard pulling in s and, mud or
deep snow.
The “4LO” indicator will come on.

AUTO LSD system
The system can be used on 2WD models and in 2WD mode on 4WD
models.
The system is activated when driving at a speed under 62 mph
(100 km/h).
The AUTO LSD system will be activated with the following two pr oce-
dures.
■TRAC off mode
Press briefly to turn on the
system. The “AUTO LSD” indi-
cator will come on.
To turn off the system, press
again.
■
AUTO LSD mode
Stop the vehicle completely,
and press for more than 3
seconds. The “AUTO LSD” and
VSC off indicators will come on.
To turn off the system, press
again.
The AUTO LSD system aids trac tion by using the traction con-
trol system to control engine performance and braking when
one of the drive wheels begins to spin.
The system should be used only when one of the drive wheels
spinning occurs in a ditch or rough surface.

■Turning off TRAC, VSC and Trailer Sway Control systems
2WD models and “2WD” mode on 4WD models
To turn the TRAC, VSC and Trailer Sway Control systems off, sto p the vehicle
completely, and press and hold for more than 3 seconds when AU TO
LSD system is on. ( P. 322)

Interior features
SEQUOIA_OM_USA_OM0C047U
■Using automatic mode
Fan speed is adjusted automatically according to the temperatur e setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.
■ Outside/recirculated air mode
●Setting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
● Outside/recirculated air mode may automatically switch dependin g on the
temperature setting, outside temperature, pressure, engine cool ant tem-
perature or inside temperature.
■ When the outside temperature exceeds 75 °F (24 °C) and the air condi-
tioning system is on
● In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the en gine switch
is turned to ON.
● It is possible to switch to outside air mode at any time by pre ssing
.
■When the outside temperature f alls to nearly 32 °F (0 °C)
The dehumidification function may not operate even when is pre ssed.

When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.
■ When the indicator light on flashes
Press
to turn off the cooling and dehumidification function and turn it on
again. There may be a problem in the air conditioning system if the indicator
light continues to flash. Turn the air conditioning system off and have it
inspected by your Toyota dealer.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the out side air mode.
● During use, various odors from inside and outside the vehicle m ay enter into
and accumulate in the air conditioning system. This may then ca use odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to o utside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short peri od of time
immediately after the air conditioning system is started in aut omatic
mode.

SEQUOIA_OM_USA_OM0C047U
WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accide nt
resulting in death o r serious injury.
●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other th an those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted o r bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not kn ow how they were used previous l y.
■When initializing the tire pressure warning system
Do not initialize tire pressure warning system without first ad justing the
tire inflation pressure to the sp ecified level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressu re is low,
or it may come on when the tire inflation pressure is actually normal.

4667-2. Steps to take in an emergency
SEQUOIA_OM_USA_OM0C047U
If your vehicle needs to be towed
If towing is necessary, we recommend having your vehicle
towed by your Toyota dealer or commercial towing service,
using a wheel-lift type t ruck or flatbed truck.
Use a safety chain system for all towing, and abide by all stat e/
provincial and local laws.
If towing your vehicle with a wheel-lift type truck from the fr ont,
the vehicle's rear wheels and axles must be in good conditions.
(
P. 466, 468)
If they are damaged, use a towing dolly or flatbed truck.
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When towing the vehicle
2WD models: Be sure to transport the
vehicle with all four wheels raised off the
ground. If the vehicle is towed with the
tires contacting the ground, the drivetrain
and related parts may be damaged or an
accident may occur due to a change in
direction of the vehicle.
4WD models: Be sure to transport the
vehicle with all four wheels raised off the
ground. If the vehicle is towed with the
tires contacting the ground, the drivetrain
or related parts may be damaged, the
vehicle may fly off the truck.
