WARNING
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This lag could cause the drive r to down-
shift again, causing rapid and excessive engine braking and pos sibly an
accident resulting in personal death or injury.
NOTICE
■ To prevent damage to the engine and its components
● Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( P. 515)
■ Voltmeter
When the voltmeter indicates 19 V or higher or 9 V or lower while the engine
is running, there may be a battery or charging system malfunction. Have the
vehicle inspected at your Toyota dealer.
■ Engine oil pressure gauge
When the value of the engine oil pressure gauge drops while the engine is
running, stop the vehicle in a safe place immediately and check the amount
of engine oil. ( P. 418)
When the oil pressure drops even though the engine oil amount has not
decreased, or if the oil pressure does not increase when engine oil is
added, contact your Toyota dealer, as there may be a problem wi th the lubri-
cation system.

1844-1. Before driving
SEQUOIA_OM_USA_OM0C047U
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an acc ident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicl e, leading to
death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
● If the brake booster device does not operate, do not follow oth er vehicles
closely and avoid hills or shar p turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
Have your brakes fixed immediately.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking dist ance will
increase.
If this happens, do not continue to drive the vehicle. Have you r brakes
fixed immediately.
■ If the vehicle becomes stuck (4WD models)
Do not spin the wheels excessively when any of the tires is up in the air, or
the vehicle is stuck in sand, mud, etc. This may damage the driveline com-
ponents or propel the vehicle forward or backward, causing an accident.

2064-1. Before driving
SEQUOIA_OM_USA_OM0C047U
●Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before maki ng
turns.
● Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by mak ing
a wider than normal turning radius.
● Slow down before making a turn, in cross winds, on wet or slipp ery
surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the lengt h of
your trailer, and be sure you have plenty of room before changi ng
lanes.
● To maintain engine braking efficiency and charging system perfo r-
mance when using engine braking, do not put the transmission in
D.
● Instability happens more frequently when descending steep or lo ng
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the bra kes
too frequently. This could cause the brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may over-
heat on hot days (at temperatures over 85 °F [30 °C]) when driv ing
up a long or steep grade. If the engine coolant temperature gau ge
indicates overheating, immediately turn off the air conditionin g (if in
use), pull your vehicle off the road and stop in a safe spot.

If the engine does not start
●The engine immobilizer system may not have been deactivated. ( P. 82)
Contact your Toyota dealer.
● Check that the shift lever is securely set in P. The engine may not start if the
shift lever is displaced out of P. “Shift to P Position” will b e displayed on the
multi-information display.
■ Steering lock
After turning the engine switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
engine switch again automatically cancels the steering lock.
■ When the steering lock cannot be released
■ Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, operation of the motor
may be suspended if the engine is turned on and off repeatedly in a short
period of time. In this case, refrain from running the engine. After about
10 seconds, the steering lock motor will resume functioning.
■ When “Smart Entry & Start System Check” is displayed on the multi-
information display
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately.
■ If the electronic key battery is depleted
P. 448
■ Operation of the engine switch
●If the switch is not pressed shortly and firmly, the engine swi tch mode may
not change or the engine may not start.
● If attempting to restart the engine immediately after turning t he engine
switch off, the engine may not start in some cases. After turni ng the engine
switch off, please wait a few seconds before restarting the eng ine.
■ If the smart key system has been d eactivated by a customized setting
P. 509 A message will be displayed on the multi-
information display.
Check that the shift lever is in P. Press the
engine switch while turning the steering
wheel left and right.

NOTICE
■Before driving
Fully release the parking brake.
Driving the vehicle with the parking brake set will lead to bra ke components
overheating, which may affect braking performance and increase brake
wear.

When trouble arises
If your vehicle overheats
●The needle of the engine coolant temperature gauge ( P. 9 4 )
enters the red zone o r a loss of engine power is experienced.
(For example, the vehicle speed does not increase.)
● Steam comes out f rom under the hood.
Stop the vehicle in a safe place and turn off the air condition ing sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radia-
tor) for any leaks. Radiator
Cooling fan
If a large amount of coolant
leaks, immediately contact your
Toyota dealer.
The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir.Reservoir
