(e) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Push the overdrive switch. The “O/D
OFF” indicator light will come on and
the transmission will downshift to fourth
gear.
Shift into the “3” position. The trans-
mission will downshift to third gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled.Tw o −wheel drive models
122 km/h (75 mph)
Four −wheel drive models
“2WD” or “4HI” mode 125 km/h (77 mph)
“4LO” mode 48 km/h (29 mph)
Shift into the “2” position. The trans-
mission will downshift to second gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled. Tw o −wheel drive models
83 km/h (51 mph)
Four −wheel drive models
“2WD” or “4HI” mode 84 km/h (52 mph)
“4LO” mode 32 km/h (19 mph)
Push the “SHIFT L” switch. The trans-
mission will downshift to first gear
when the vehicle speed drops down to
or lower than the following speed, and
maximum engine braking will be en-
abled. Tw o −wheel drive models
35 km/h (21 mph)
Four −wheel drive models
“2WD” or “4HI” mode 36 km/h (22 mph)
“4LO” mode 14 km/h (8 mph) When the cruise control is being used,
even if you downshift the transmission by
pushing and releasing the overdrive
switch, engine braking will not be enabled
because the cruise control is not can-
celled.
For ways to decrease the vehicle speed,
see “Cruise control” on page 205 in this
Section.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to skid or
spin.

(f) Using the “3”, “2” and “L”, posi-tions
The “3”, “2” and “L” positions are used for
strong engine braking as described pre-
viously.
With the selector lever in “3”, “2” or
“SHIFT L” switch depressed, the vehicle
can start just as if the lever was in “D”.
With the selector lever in “3” or “2”, the
vehicle will start in first gear and automat-
ically shift to second gear.
With the “SHIFT L” switch depressed, the
transmission is engaged in first gear.NOTICE
 Be careful not to overrev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given above for your reference:
Twowheel drive models “3” 135 km/h (84 mph) . . . . . . .
“2” 90 km/h (56 mph) . . . . . . . .
“L” 50 km/h (31 mph) . . . . . . . .
Fourwheel drive models “2WD” or “4HI” mode“3” 135 km/h (84 mph) . . . . . . .
“2” 90 km/h (56 mph) . . . . . . . .
“L” 50 km/h (31 mph) . . . . . . . .
“4LO” mode “3” 50 km/h (31 mph) . . . . . . . .
“2” 35 km/h (21 mph) . . . . . . . .
“L” 20 km/h (12 mph) . . . . . . . .
 Do not continue hill climbing or
hard towing for a long time in the
“3”, “2” or “L” position. This may
cause severe automatic transmis-
sion damage from overheating. To
prevent such damage, “D” position
should be used in hill climbing or
hard towing.
(g) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
“R” position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(h) Parking
1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, shift the selector lever to the “P” posi-
tion.
CAUTION
Never attempt to move the selector
lever into “P” position under any cir-
cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.

If the automatic unlocking operation linked
to shift lever position is set, all doors are
automatically unlocked when the selector
lever is moved to “P” position after the
ignition switch is turned to “ON” position.
For details, see “—Automatic door locking
and unlocking functions” on page 27 in
Section 1−2.
(i) Good driving practice
If the transmission repeatedly shifts up
and down between fourth gear and
overdrive when climbing a gentle slope,
the overdrive should be turned off. Be
sure to turn the switch on immediately
afterward.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.
CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
NOTICE
Always use the brake pedal or the
parking brake to hold the vehicle on
an upgrade. Do not attempt to hold
the vehicle using the accelerator ped-
al, as this can cause the transmission
to overheat.
Front drive control switches

Fourwheel drive system—
(a) Front drive control

’06_SEQUOIA_U (L/O 0508)
178
Use the front drive control switches
and center differential lock switch to
select the transfer and center differen-
tial modes.
In the “4HI” and “4LO” mode, you can
choose to lock or unlock the center differ-
ential.
Use the center differential lock system if
your wheels get stuck in a ditch, or when
you are driving on a slippery or bumpy
surface. When the center differential is
locked, the vehicle stability control system
is automatically turned off and the center
differential lock and “VSC OFF” indicator
lights come on because the function that
controls engine performance interferes
with the process of freeing your wheels.
NOTICE
As soon as the center differential lock
switch is turned on, the “VSC OFF”
indicator light comes on. After the
wheels are out of the ditch or off the
slippery or bumpy surface, turn the
center differential lock switch off.
Make sure that the center differential
lock indicator light and “VSC OFF”
indicator light turn off.
“2WD” mode (high speed, twowheel
drive)
This mode is the normal driving mode. In
this mode, the “4HI” and “4LO” indicator
lights are turned off.
Use this for normal driving on dry hard−
surfaced roads. This position gives greater
economy, quietest ride, least wear and
better vehicle control.
“4HI” mode (high speed, fourwheel
drive, center differential unlocked)
To select this mode, press the “2WD/4HI”
switch only. The “4HI” indicator light
comes on.
Use this for normal driving on all types of
roads, from dry hard −surfaced roads to
wet, icy or snow −covered roads. This
position provides greater traction than
two −wheel drive. “4HI” mode (high speed, fourwheel
drive, center differential locked)
To select this mode, press the “2DW/4HI”
switch, and then the center differential
lock switch. The “4HI” and the center dif-
ferential lock indicator lights come on.
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the center differential
unlock mode.
“4LO” mode (low speed, fourwheel
drive, center differential unlocked)
To select this mode, press the “4LO”
switch only. The “4LO” indicator light
comes on.
Use this for maximum power and traction.
Use this for climbing steep hills, off
−road
driving, and hard pulling in sand or mud.
In this mode, the braking feeling that oc-
curs when the wheels are negotiating a
sharp corner is further reduced than in the
“4LO” (low speed, four −wheel drive, center
differential locked) mode.

’06_SEQUOIA_U (L/O 0508)
179
“4LO” mode (low speed, fourwheel
drive, center differential locked)
To select this mode, press the “4LO”
switch, and then press the center differen-
tial lock switch. The “4LO” and the center
differential lock indicator lights come on.
Use this for maximum power and traction.
Use this for hard pulling in situations the
vehicle cannot negotiate even in “4LO”
(low speed, four−wheel drive, center differ-
ential unlocked) mode. Also, using this
mode when driving down steep off −road
inclines will help contribute to increased
vehicle stability.
The indicator light tells when the differen-
tial lock is engaged. Note that the differ-
ential is not still locked as long as the
indicator light remains off.
When the operation is not completed, the
indicator blinks. If the indicator light does
not go off when you push out the center
differential lock switch, drive straight
ahead while accelerating or decelerating,
or drive in reverse.
If the center differential lock system op-
eration is not completed within 5 seconds
while the cruise control system is set,
cancel the cruise control system. To can-
cel the cruise control system, see “Cruise
control” on page 205 in Section 1 −7. If the indicator blinks even if doing so,
contact your Toyota dealer as soon as
possible. There may be a trouble in the
center differential lock system.
See “(c) Shifting procedure” for further in-
structions.
Advice for driving on slippery roads in
“4LO” (low speed, fourwheel drive)
mode
If you press the “4LO” switch and shift
the automatic transmission lever to “2”
when you drive in steep off
−road areas,
the output of the brake can be controlled
effectively by the active traction control
system, which assists the driver to control
the driving power of 4 wheels.
Use the “L” position of the automatic
transmission for maximum power and trac-
tion when your wheels get stuck or when
you drive down a steep incline. The output
of the brake can be controlled by the
active traction control system if the engine
speed is under 3000 rpm (normally engine
speed is under 3000 rpm when the wheels
get unstuck), in the following cases:
The front drive control in “4LO” mode
and the automatic transmission in “L”
or the automatic transmission in “D”,
“3” or “2” with the transmission down-
shifting to the first gear
The front drive control in “4LO” mode
and the automatic transmission in “R”
(As for the automatic transmission shift
positions, see “Automatic transmission” on
page 173 in this Section.)

The A.D.D. can be engaged or disen-
gaged by the shifting operations des-
cribed in “(c) Shifting procedure”.
You should drive in four−wheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated. SHIFTING BETWEEN “2WD” MODE AND
“4HI” MODE
To shift from “2WD” mode to “4HI”
mode,
reduce your speed to less than
100 km/h (62 mph) and press the
“2WD/4HI” switch.
If the “4HI” indicator light flashes when
you press the “2WD/4HI” switch, drive
straight ahead while accelerating or decel-
erating.
If the “4HI” indicator light flashes and the
buzzer sounds when you press the
“2WD/4HI” switch, reduce the vehicle
speed to less than 100 km/h (62 mph)
and press the switch again.
CAUTION

The traction control system automatical-
ly helps prevent the spinning of rear
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against rear wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.
NORMAL DRIVING MODE
Leave the system on during the ordi-
nary driving so that it can operate
when needed.
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the trac-
tion control system is in the self−check
mode, but does not indicate a malfunction. When the traction control system is oper-
ating, the following conditions occur:
The system controls the spinning of the
rear wheels. At this time, the slip indi-
cator light blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.
