tire type TOYOTA TUNDRA 2007 2.G Owners Manual

2482007 TUNDRA from Jul. ’07 Prod. (OM34463U)
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.)

IF THE TIRE PRESSURE WARNING
LIGHT COMES ON AFTER BLINKING
FOR 1 MINUTE...
If the tire pressure warning light comes
on after blinking for 1 minute when the
ignition switch is turned to the “ON”
position, the tire pressure warning sys-
tem is not working properly.
The system will be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work properly.)
If tires not equipped with tire pressure
warning valves and transmitters are
used.
If the ID code on the tire pressure
warning valves and transmitters is not
registered in the tire pressure warning
computer.
The system may be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work pr operly.)
If electronic devices or facilities using
similar radio wave frequencies are
nearby.
If a radio set at similar frequencies is
in use in the vehicle.
If a window tint that affects the radio
wave signals is installed.
If there is a lot of snow or ice on the
vehicle, in particular around the wheels
or wheel housings.
If non−genuine Toyota wheels are used.
If tire chains are used.
If the tire pressure warning light continues
to come on after blinking for 1 minute
when the ignition switch is turned to the
“ON” position, have the system checked
by your Toyota dealer.
Even if you use genuine wheels, the tire
pressure warning system may not work
properly with some types of tires.
Pushing the tire pressure warning reset
switch should not turn off the tire pressure
warning light.

7. “TUBELESS” or “TUBETYPE”— A tubeless tire does not
have a tube inside the tire and air
is directly filled in the tire. A tube
type tire has a tube inside the tire
and the tube maintains the air
pressure.
8. Load limit at maximum cold tire inflation pressure— For details,
see “Checking and replacing tires”
on page 551.
9. Maximum cold tire inflation pressure— This means the pres-
sure to which a tire may be in-
flated. For details about recom-
mended cold tire inflation
pressure, see “Tires” on page 586.
10.Summer tire or all season tire— An all season tire has “M+S”
on the sidewall. The tire not
marked with “M+S” is a summer
tire. For details, see “Types of
tires” on page 466.

Determine what kind of tires your
vehicle is originally equipped with.1. Summer tires
Summer tires are high −speed capabil-
ity tires best suited to highway driving
under dry conditions.
Since summer tires do not have the
same traction performance as snow
tires, summer tires are inadequate for
driving on snow −covered or icy roads.
For driving on snow −covered or icy
roads, we recommend using snow
tires. If installing snow tires, be sure
to replace all four tires.
2. All season tires
All season tires are designed to pro-
vide better traction in snow and to be
adequate for driving in most winter
conditions, as well as for use all year
round. All season tires, however, do not have
adequate traction performance
compared with snow tires in heavy or
loose snow. Also, all season tires fall
short in acceleration and handling
performance compared with summer
tires in highway driving.
The details about how to distinguish
summer tires from all season tires are
described on page 451.
CAUTION

Do not mix summer and all sea-
son tires on your vehicle as
this can cause dangerous han-
dling characteristics, resulting
in loss of control.
 Do not use tires other than the
manufacture’s designated
tires, and never mix tires or
wheels of the sizes different
from the originals.

SERVICE CONNECTOR FOR TOWING
BRAKE CONTROLLER (with towing
package)
Your vehicle is equipped with a service
connector for the trailer brake controller
as shown.
Access the service connector.
1. Remove the scuff plate.
2. Remove the clip (screw type) and trim board.
Remove the connector cover from the ser-
vice connector before connecting the con-
nector.
Link the connector to the trailer brake
controller via the sub wire harness stored
in the glove box. The detailed explanation
of the sub wire harness circuit is packed
together with the sub wire harness.
Be sure to position the trailer brake con-
troller where it does not prevent the driver
from operating the pedal.
Toyota recommends that the sub wire har-
ness be stored in the glove box when it
is not in use. TIRES
Ensure that your vehicle’s tires are
properly inflated. See page 548 in Sec-
tion 7
−2 and page 586 in Section 8 for
instructions.
The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the gross
trailer weight.

3. Visually check to see if the enginedrive belt (fan belt) is broken or loose.
Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the engine drive belt is broken or thecoolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as-
sistance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir while the
engine is running. Fill it about half full.
For the coolant type, See “Coolant type
selection” on page 546 in Section 7 −2.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
7. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You should have it checked as
soon as possible at your Toyota dealer.
1. Reduce your speed gradually, keeping a straight line. Move cau-
tiously off the road to a safe place
well away from the traffic. Avoid
stopping on the center divider of
a highway. Park on a level spot
with firm ground.
2. Stop the engine and turn on your emergency flashers.
3. With the transmission in “P” firmly set the parking brake.
4. Have everyone get out of the ve- hicle on the side away from traffic.
5. Read the following instructions thoroughly.
If you have a flat tire—
