2015 TOYOTA SEQUOIA engine

152 2-1. Driving procedures
CAUTION
■When the vehicle is parked
●If the shift lever is moved before the 4LO indicator turns on/off, the transfer
mode may not be shifted completely. The transfer mode disengages both
the front and rear driveshafts from the powertrain and allows the vehicle to
move regardless of the shift position. (At this time, the indicator blinks and
the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode. ( P. 248)
● Do not touch the exhaust pipe while the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
● Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle. This may lead
to death or a serious health hazard.
■ Exhaust gases
Exhaust gases include harmful carbon monoxide (CO) that is colorless and
odorless. Inhaling exhaust gases may lead to death or a serious health haz-
ard.
●If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
● The exhaust should be checked occasionally. If there is a hole or crack
caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by your Toyota dealer.
Failure to do so may allow exhaust gases to enter the vehicle, resulting in
death or a serious health hazard.

When driving
CAUTION
■
When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift
lever or depress the accelerator pedal, which could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leadin\
g to
death or a serious health hazard.
■ When braking the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and 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 power brake assist function does not operate, do not follow other
vehicles closely and avoid downhills or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the
pedal than usual. Braking distance may also 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 braking distance
becomes longer.
Have your brakes fixed immediately.

NOTICE
■
When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle.
●Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following.
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, trans-
mission, transfer (4WD models), differentials, etc.
● Lubricant condition for the propeller shaft, bearings and suspension joints
(where possible) and the function of all joints, bearings, etc.

2-1. Driving procedures
Engine (ignition) switch
■Engine switch
LOCK
The steering wheel is locked
and the key can be removed.
(The key can be removed only
when the shift lever is in P.)
ACC
Some electrical components
such as the audio system can
be used.
ON
All electrical components can
be used.
START
For starting the engine.
■Starting the engine
Check that the parking brake is set.
Check that the shift lever is set in P.
Sit in the driver’s seat and firmly depress the brake pedal.
Turn the engine switch to the START position and start the
engine.
The engine will crank until it starts or for up to 25 seconds, which-
ever is less. If you turn the engine switch, the engine will keep
cranking for about 30 seconds maximum.
Continue depressing the brake pedal until the engine is com-
pletely started.

When driving
■
Turning the key from ACC to LOCK
■ Steering lock release
■ If the engine does not start
The engine immobilizer system may not have been deactivated. ( P. 104)
■ Key reminder function
A buzzer sounds if the driver’s door is opened, while the engine switch is in
the ACC or LOCK position to remind you to remove the key.
CAUTION
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
Do not turn the engine switch to the LOCK position.
If in an emergency, you must turn the engine off while the vehicle is moving,
turn the engine switch only to the ACC position.
Shift the shift lever to P.
(P. 159)
Push in the key and turn to the
LOCK position.
When starting the engine, the engine
switch may seem stuck in the LOCK posi-
tion. To free it, turn the key while turning
the steering wheel slightly in either direc-
tion.

158 2-1. Driving procedures
NOTICE
■To prevent battery discharge
Do not leave the engine switch in the ACC or ON position for long periods if
the engine is not running.
■ When starting the engine
●Do not crank for more than 30 seconds at a time. This may overheat the
starter and wiring systems.
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.

When driving
Automatic transmission
Select a shift position appropriate for the driving conditions.
■Shifting the shift lever
While the engine switch is on, depress the brake pedal and
move the shift lever.
■ Shift position uses
*1: To improve fuel consumption and reduce noises, set the shift lever in
D for normal driving.
*2: Selecting shift ranges S mode restricts the upper limit of the possiblegear ranges, control engine braking forces, and prevents unneces-
sary upshifting.

Changing shift ranges in S modeShift the shift lever to the S position and operate the shift lever. Upshifting
Downshifting
The initial shift range in S mode is automatically set to 5 or 4 accord-
ing to vehicle speed. However, the initial shift range may be set to 3
or 2 if the AI-SHIFT has operated while the shift lever was in the D
position. (
P. 161)
■ Shift ranges and their functions
A lower shift range will provide greater engine braking forces than a higher
shift range.

vehicle speed and driving conditions.
5Automatically selecting gears between 1 and 5 according to
vehicle speed and driving conditions.
