2007 TOYOTA TUNDRA check engine light

2352007 TUNDRA from Jul. ’07 Prod. (OM34463U)
When the “S” mode indicator light does
not come on even with the selector lever
moved to the “S” position, there may be a
problem somewhere in the system. Have
your vehicle checked/repaired by your
Toyota dealer as soon as possible. In this
case, you can drive in the same condition
as in the “D” position.
(d) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
When driving in the “D” position—Shift the selector lever to the “S”
position.
When driving in the “6” range within
the “S” position— Turn the “S” mode switch of the se-
lector to the “ −” side to select the “5”
range. The transmission will down-
shift to fifth range when the vehicle
speed drops down to or lower than
the following speed, and engine brak-
ing will be enabled. 5.7 L V8 (3UR
−FE) engine
Four −wheel drive models
—Front drive control switch knob
at “4L” 79 km/h (49 mph)
. . . . . . . . . . . . . . .
When the cruise control is being used,
even if you downshift the transmission,
engine braking will not be enabled be-
cause the cruise control is not can-
celled. However, engine braking will be
automatically enabled if the vehicle
speed is higher than the set speed of
the cruise control depending on the
driving conditions.
For ways to decrease the vehicle
speed, see “Cruise control” on page
259 in this Section.
Turn the “S” mode switch of the selec-
tor to the “ −” side to select the “4”
range. The transmission will downshift
to fourth range when the vehicle speed
drops down to or lower than the follow-
ing speed, and stronger engine braking
will be enabled. 5.7 L V8 (3UR
−FE) engine
Four −wheel drive models
—Front drive control switch knob
at “4L” 79 km/h (49 mph)
. . . . . . . . . . . . . . .
When the cruise control is being
used, even if you downshift the
transmission, engine braking will not
be enabled because the cruise con-
trol is not cancelled. However, engine
braking will be automatically enabled
if the vehicle speed is higher than
the set speed of the cruise control
depending on the driving conditions.
Turn the “S” mode switch of the selec-
tor to the “ −” side to select the “3”
range. The transmission will downshift
to third range when the vehicle speed
drops down to or lower than the follow-
ing speed, and more powerful engine
braking than that of the “4” range posi-
tion will be enabled.

The traction control system automatical-
ly helps prevent the spinning of rear
wheels (twowheel drive models) or 4
wheels (fourwheel drive models) when
the vehicle is started or accelerated on
slippery road surfaces.
When the ignition switch is turned to the
“ON” position, the system automatically
turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power to the rear wheels (twowheel
drive models) or 4 wheels (fourwheel
drive models) cannot be maintained,
even though the traction control sys-
tem is in operation. Do not drive the
vehicle under any speed or maneuver-
ing conditions which may cause the
vehicle to lose traction control. In si-
tuations where the road surface is
covered with ice or snow, your ve-
hicle should be fitted with snow tires
or tire chains. Always drive at an ap-
propriate and cautious speed for the
present road conditions.

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 (two −wheel drive models)
or 4 wheels (four −wheel drive models).
At this time, the slip indicator 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 switch is turned
to the “ON” position. If the indicator light
does not come on when the ignition is
turned on, contact your Toyota dealer.

The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the output of the brakes or engine to
help prevent the vehicle from skidding
when cornering on a slippery road sur-
face or operating steering wheel abrupt-
ly.
The vehicle stability control system is acti-
vated when the vehicle speed is more
than 15 km/h (9 mph).
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 sys-
tem is in the self−check mode, but does
not indicate a malfunction.CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid serious injury. Reckless driv-
ing will result in an unexpected ac-
cident. If the slip indicator light
blinks and an alarm sounds, special
care should be taken while driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” on
page 551 in Section 72.)

When getting the vehicle out of mud or
newly fallen snow, etc., it may be bene-
ficial to turn off the vehicle stability
control system. This system that con-
trols engine performance interferes with
the process of freeing rear wheels
(twowheel drive models) or 4 wheels
(fourwheel drive models).
To turn off: First, push the “VSC OFF”
switch to turn off the traction control
system and check that the “AUTO LSD”
and slip indicator lights come on. Then,
push and hold the “VSC OFF” switch

stopped.
The “VSC OFF” and slip indicator lights
will come on.To turn on: Briefly push the “VSC OFF”
switch once again.
The “VSC OFF” and slip indicator lights
will go off.
If the engine is turned off while the “VSC
OFF” and slip indicator lights are on and
then restarted, the indicator lights will turn
off automatically.
When you briefly push the “VSC OFF”
switch, turn off the vehicle stability control
system. See “Traction control system” on
page 242 in this Section.
The “VSC OFF” and slip indicator lights
come on for a few seconds when the
ignition switch is turned to the “ON” posi-
tion. If the indicator lights do not come on
when the ignition switch is turned to the
“ON” position, contact your Toyota dealer.
CAUTION
Do not drive with the vehicle stability
control system continuously turned
off.

1. Check the area around the vehicle be-fore entering it.
2. Adjust seat position, seatback angle, seat cushion angle, head restraint
height and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts. Once you turn the ignition switch to the
“START” position and release it, the crank-
ing hold function continues to crank the
engine in “ON” position until it starts.
The function stops cranking the engine
after about 25 seconds maximum if the
engine has not started yet. When you
crank the engine again, wait a few sec-
onds and restart it.
If you hold the ignition switch in “START”
position, the function will keep cranking
for about 30 seconds maximum. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces-
sories.
3. Put the selector lever in “P”. If you need to restart the engine while the
vehicle is moving, put the selector le-
ver in “N”. A starter safety device will
prevent the starter from operating if the
selector lever is in any drive position.
4. Depress the brake pedal and hold it to the floor until driving off.

Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.
Four−wheel drive models—Toyota rec-
ommends not using four −wheel drive on
dry hard− surfaced roads, because four −
wheel driving will cause unnecessary
noise and wear, and poor fuel econo-
my.
Four −wheel drive models—In cold tem-
peratures, noise may occur when driv-
ing in two −wheel drive before the trans-
fer is warmed up. Therefore, first drive
in four −wheel drive until the transfer is
warmed up.
CAUTION
Before driving off, make sure that
the parking brake is fully released
and the brake system warning light
(parking brake reminder light) is
off.
Do not leave your vehicle unat-
tended while the engine is running.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking, could cause
the vehicle to skid or spin.
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has highspeed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are highspeed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a
longer stopping distance, and it
may pull to one side when the
brakes are applied. Also, the park-
ing brake will not hold the vehicle
securely.

Driving in the rain
Driving on a slippery road surface
Drive carefully when it is raining, because
visibility will be reduced, the windows may
become fogged− up, and the road will be
slippery.
Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
Refrain from high speeds when driving
on an expressway in the rain, because
there may be a layer of water between
the tires and the road surface, prevent-
ing the steering and brakes from oper-
ating properly.
CAUTION
Sudden braking, acceleration and
steering when driving on a slippery
road surface may cause tire slip-
page and reduce your ability to
control the vehicle, resulting in an
accident.
Sudden changes in engine speed,
such as sudden engine braking,
may cause the vehicle to skid, re-
sulting in an accident.
After driving through a puddle,
lightly depress the brake pedal to
make sure that the brakes are func-
tioning properly. Wet brake pads
may prevent the brakes from func-
tioning properly. If the brakes on
only one side are wet and not func-
tioning properly, steering control
may be affected, resulting in an ac-
cident.
When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
serious damage to the vehicle.
NOTICE
Driving on a flooded road may cause
the engine to stall as well as cause
serious vehicle malfunctions such as
shorts in electrical components and
engine damage from 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 brake function, changes
in quantity and quality of oil and fluid
used for the engine, transmission,
transfer (4WD vehicles), differentials,
etc. and lubricant condition for the
propeller shaft, bearings and suspen-
sion joints (where possible) and the
function of all joints and bearings.

TOWING CONNECTOR FOR TRAILER
LIGHTS
Your vehicle is equipped with wire har-
ness sockets for trailer lights under the
rear bumper. Use them to connect and
operate the trailer lights. However, the
trailer lights must comply with federal,
state/provincial and local regulations.
See your local recreational vehicle
dealer or rental agency for the correct
type of wiring and relays for your trail-
er. Check for correct operation of the
turn signals and stop lights each time
you hitch up. Direct splicing may dam-
age your vehicle’s electrical system
and cause a malfunction of your lights.
The towing connector can be also con-
nected to the trailer brake and trailer
sub battery.BREAKIN SCHEDULE
If your vehicle is new or equipped with
any new power train components (such
as the engine, transmission, differential
and wheel bearing), Toyota recom-
mends that you do not tow a trailer
until it has been driven for over 800
km (500 miles). After the vehicle has
been driven for over 800 km (500
miles), you can start towing. However,
drive the vehicle at a speed of less
than 80 km/h (50 mph) when towing a
trailer for another 800 km (500 miles).
In addition, avoid full throttle accelera-
tion.
MAINTENANCE
If you tow a trailer, your vehicle will
require more frequent maintenance due
to the additional load. For this
information, please refer to the
scheduled maintenance information in
the “Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.
Retighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving.
