2007 TOYOTA LAND CRUISER engine

162
To initialize the system, perform the fol-
lowing:1. Park the vehicle in a safe place and the engine is off.
2. Adjust the pressure of all the installed tires to the specified cold tire inflation
pressure level. (See “Tires” on page
354.)
3. Turn the ignition switch to the “ON” position.
4. Push and hold the tire pressure warn- ing reset switch until the tire pressure
warning light blinks slowly three times.
5. Wait for a few minutes with the ignition switch “ON”, and then turn the ignition
switch to the “OFF” position.
If you push the tire pressure reset switch
while the vehicle is moving, initialization is
not performed.
If you push the tire pressure reset switch
accidentally and initialization is performed,
adjust the tire inflation pressure to the
specified level and initialize the system
again.
16c522a
If the tire pressure warning light does not
blink slowly three times when you push
and hold the reset switch, initialization has
failed and the tire pressure warning sys-
tem may not work properly. In this case,
initialize the system again. If initialization
cannot be performed, have the system
checked at your Toyota dealer.
CAUTION
Do not push the reset switch without
first adjusting the tire inflation pres-
sure to the specified level. Other-
wise, the tire pressure warning light
may not come on even if the tire
inflation pressure is low, or it may
come on when the tire inflation pres-
sure is actually normal.

164
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
Cruise control
The cruise control is designed to main-
tain a set cruising speed without requir-
ing the driver to operate the accelera-
tor. Cruising speed can be set to any
speed above 40 km/h (25 mph).
Within the limits of the engine’s capabili-
ties, cruising speed can be maintained up
or down grades. However, changes in ve-
hicle speed may occur on steeper grades.
When the cruise control is on, the driving
pattern of the automatic transmission is
fixed in the normal position, regardless of
the position of the driving pattern selector
switch.CAUTION
To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snow
–covered) or
winding roads.
Avoid vehicle speed increases when
driving downhill. If the vehicle
speed is too fast in relation to the
cruise control set speed, cancel the
cruise control then downshift the
transmission to use engine braking
to slow down.

166
If you need acceleration—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CANCELLING THE CRUISE CONTROL
The cruise control may be temporarily
cancelled by the driver or by the system
itself under certain circumstances. Tempo-
rary cancellation allows the set cruising
speed to remain in memory.
The cruise control can be temporarily can-
celled by doing the following:
Pulling the lever in the “CANCEL”
direction and releasing it
Depressing the brake pedal
Under certain circumstances, the cruise
control is temporarily cancelled:
When vehicle speed falls below 40
km/h (25 mph)
When vehicle stability control is acti-
vated
When vehicle speed drops 16 km/h (10
mph) below the set speed, the cruise con-
trol is cancelled and the set speed is
erased from memory. The “CRUISE” indicator light remains on
to indicate that the system is still in op-
eration.
To turn the cruise control off, push the
“ON
−OFF” button. Make sure the
“CRUISE” indicator light is off.
If the cruise control automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESUMING THE CRUISE CONTROL
If the cruise control is temporarily can-
celled, the cruising speed can be resumed
by pushing the lever up in the “+ RES”
direction.
Vehicle speed must be above 40 km/h (25
mph).
RESETTING TO A FASTER SPEED
Push the lever up in the “+ RES” direction
and hold it. Release the lever when the
desired speed is attained. While the lever
is held up, the vehicle will gradually gain
speed.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
control lever down in the “– SET” direc-
tion. RESETTING TO A SLOWER SPEED
Push the lever down in the “– SET” direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held down, the vehicle speed will
gradually decrease.
However, a faster way to reset is to de-
press the brake pedal and then push the
control lever down in the “– SET” direc-
tion.
Even if you downshift the transmission
from the “D” position to “4” with the cruise
control on, engine braking will not be ap-
plied because the cruise control is not
cancelled. To decrease the vehicle speed,
reset to a slower speed with the cruise
control lever or depress the brake pedal.
If you use the brake pedal, cruise control
is cancelled.
CRUISE CONTROL FAILURE WARNING
If the “CRUISE” indicator light flashes
when using the cruise control, press the
“ON
−OFF” button to turn the system off
and then press it again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.
The indicator light does not come on.
The indicator light flashes again.

(b) Automatic leveling function
Regardless of the number of occupants
or the luggage loading condition, the
vehicle height is always automatically
adjusted to a fixed height in any mode.
However, the vehicle height cannot be
raised if the vehicle load exceeds the lim-
its. (See “(d) Vehicle height adjustment”
described below.)(c) Vehicle height mode changing
condition
To change the vehicle height, it is nec-
essary to meet the following 3 condi-
tions.
The engine should be running.
All the side doors and back door
should be closed.
The height control “OFF” indicator
light should go off.
When selecting a mode with the four −
wheel drive control lever at “H”, there is
a vehicle speed limit. Refer to the follow-
ing table.
Yes = The mode can be selected.
No = The mode cannot be selected.

In the following cases the active height
control suspension does not operate
even if the above conditions are all
met.
The brake pedal has been depressed
for longer than about 5 seconds with
the vehicle stopped.
The suspension fluid temperature is
lower than –30 C (–22 F). If the en-
gine is warmed up, the suspension
fluid temperature will be raised as the
inside of the engine compartment be-
comes warmer. Then the active height
control system becomes operable.
Driving on the bumpy roads, which
may cause the suspension to fully
elongate.
The steering wheel is operated abruptly
more than 3/4 turns with center differ-
ential lock system activated.

Selecting the high mode—
Push the height select switch on the “
”
side when the vehicle speed is under
about 30 km/h (19 mph).
To change the normal mode to high,
push the switch once.
To change the low mode to high, push
the switch twice. It takes about 30 se-
conds until the low mode changes to the
high mode.
Selecting the normal mode—
To change the high mode to normal,
push the height select switch on the “
”
side once.
To change the low mode to normal,

” side while the vehicle is stopped.
To change the high mode to low, push
the switch twice.
To change the normal mode to low,
push the switch once.
NOTICE
Do not select the low mode in the
bumpy roads. If the underbody of the
vehicle touches the rugged road sur-
face, the vehicle may be damaged.
Even if the engine is stopped while the
vehicle height is being lowered, the op-
eration continues for up to 12 seconds.
(e) Turning off the active height control suspension
To turn off the active height control
suspension with the vehicle stopped,
push the height control switch. The
height control “OFF” indicator light
comes on and the vehicle height is
fixed in the same mode as the height
control switch is pushed.
This status is memorized in the system
even after the engine is stopped.
If you push the switch again, the height
control “OFF” indicator light goes out and
the active height control suspension is
turned on.

172
CAUTION
If you drive through deep water over
about 500 mm (20 in.) in depth, put
the vehicle height in the HI (High)
mode with the active height select
switch and then turn off the active
height control suspension by pushing
the height control switch. Drive your
vehicle at 30 km/h (19 mph) or lower
speed.
NOTICE
When jacking up or insta lling tire
chains, be sure to turn off the ac-
tive height control suspension and
stop the engine. Otherwise, the ve-
hicle height may change because of
the automatic leveling function, re-
sulting in an accident.
 If your vehicle must be towed, put
the vehicle height in the normal
mode and turn off the active height
control suspension. Otherwise, the
vehicle height may change because
of the automatic leveling function,
resulting in an accident.
If your vehicle gets ditched, turn off
the active height control suspension
with the height control switch.
Otherwise, the vehicle height may
change because of the automatic
leveling function, resulting in an ac-
cident.
Even after the active height control
suspension is turned off with the height
control switch, if the vehicle speed ex-
ceeds 30 km (19 mph), the active height
control automatically selects the normal
mode.
(f) Height control indicator lights
1. Height control indicator lights
2. Height control “OFF” indicator light
When the ignition switch is turned on,
all the indicator lights come on. The
indicator light showing the present
mode only remains on and all other
lights go off after a few seconds. This
means the system operates correctly.

174
Height control “OFF” indicator light:
When the ignition switch is turned on, this
light comes on. If it goes out after a few
seconds, the active height control suspen-
sion operates correctly. If you push the
height control switch, the active height
control is turned off. The height control
“OFF” indicator light comes on.
In the following cases, there is a problem
somewhere in your active height control
suspension. Although there is no problem
to continue normal driving, have the active
height control suspension checked by your
Toyota dealer as soon as possible.
The height control “OFF” indicator light
does not come on when the ignition
switch is turned on.
The height control “OFF” indicator light
blinks.(g) Operation in cold weather
The active height control suspension
does not operate in cold weather when
the suspension fluid temperature drops
below –30
C (–22 F).
In this case, operating the height control
switch does not change the vehicle height.
The vehicle height control enters the
ready mode and the selected height con-
trol indicator light blinks. The active height
control becomes operable if the engine is
warmed up with the suspension fluid tem-
perature being raised within normal operat-
ing limits. The vehicle changes to the se-
lected height when the vehicle height
control is in the ready mode.
When the suspension fluid temperature is
around –30 C (–22 F), the vehicle height
cannot be raised even within the available
load capacity. After warming up the en-
gine, push the control switch on the “
”
side once and then on the “
” side to
select the desired vehicle height.
It takes longer to change the vehicle
height when the suspension fluid tem-
perature drops below –15 C (5 F). (h) Parking and stopping tips
If you immediately stop the engine to park
the vehicle after off
−road driving, the ve-
hicle height is lowered slightly as the ve-
hicle becomes cool. When parking, make
sure there is nothing that will be in con-
tact with the underbody of the vehicle.
When you start the engine, the vehicle
returns to the previous height.
If you park the vehicle for a long time,
the vehicle height may be gradually low-
ered. When parking for a long time, make
sure there is nothing that will be in con-
tact with the underbody of the vehicle.
When you start the engine, the vehicle
returns to the previous height.
If you stop the engine, the vehicle height
may change in accordance with the
change in the temperature. When you
start the engine, the vehicle returns to the
previous height.

(i) Installing or removing heavy equip-
ment
If you install or remove heavy equipment
exceeding 15 kg (33 lb.), the front torsion
bar should be adjusted. Consult your To-
yota dealer.
(j) Active height control failure warning
If there is a problem somewhere in the
active height control suspension, the nor-
mal mode is automatically selected. If this
occurs, the height control “OFF” indicator
light blinks and the vehicle height control
cannot be activated until the malfunction
is corrected.
Stop the engine and start it again. If the
height control “OFF” indicator light goes
out, the active height control suspension
returns to normal. If the height control
“OFF” indicator blinks again, bring your
vehicle to your Toyota dealer as soon as
possible and have it checked.
This skyhook TEMS adjusts the damp-
ing effect on the shock absorbers with
the damping mode select switch. Select
one of the 4 modes which is suited to
the driving conditions with the damping
mode select switch to provide good rid-
ing comfort and stability.
1. For driving on a bumpy road
2. For ordinary driving such as in the city traffic
3. For moderate high speed driving
4. For sporty type driving such as on winding mountain roads and high speed
driving We recommend you to select the mode 2
for ordinary driving. The damping effect
will be changed automatically to provide
good riding comfort.
When your vehicle is loaded heavily or
you are driving in an unpaved road, the
mode 3 or 4 will be recommended. To
provide good vehicle stability, the damping
effect will be harder than for ordinary driv-
ing mode.
With the four
−wheel drive control lever at
“L”, the damping effect suitable for off −
road driving will be harder in any mode.
