2007 TOYOTA TUNDRA engine overheat

1832007 TUNDRA from Jul. ’07 Prod. (OM34463U)
The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle moves into the red zone,
your engine is too hot. If your vehicle
overheats, stop your vehicle and allow the
engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air
conditioning on in stop−and− go traffic.
Towing a trailer.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your
vehicle overheats” in Section 4.

“1” (First range):
The gear is fixed in first regardless of
vehicle speed and driving conditions.
This range is to be used when maxi-
mum engine braking is necessary.
If you attempt to downshift the transmis-
sion when it is not possible to downshift
due to high vehicle speed, a warning tone
sounds twice.
NOTICE
Do not drive in the “3”, “2” or “1”
range when driving at high speed or
climbing a gentle slope for a long
time. Otherwise the transmission or
engine may overheat causing damage.
Maximum allowable speeds
To get on a highway or to pass slower
traffic, maximum acceleration may be nec-
essary. Make sure you observe the follow-
ing maximum allowable speed in each

(e) Backing up1. 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.
(f) 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.
(g) Good driving practice
If the transmission repeatedly shifts up
and down between third gear and over-
drive when climbing a gentle slope,
shift the selector lever into “S” posi-
tion.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use the transmission in “D”. Select an
appropriate shift range in “S” mode.
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.
(h) If you cannot shift the selector le- ver out of “P” position
If you cannot shift the selector lever from
the “P” position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see “If
you cannot shift automatic transmission
selector lever” on page 516 in Section 4.

CAUTION
Be careful when downshifting on a
slippery surface. The abrupt change
in engine speed could cause the ve-
hicle to skid or spin.

(g) Good driving practice
If the transmission repeatedly shifts up
and down between fourth gear and
overdrive when climbing a gentle slope,
shift the selector lever into “S” posi-
tion.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use the transmission in “D”. Select an
