“START”—Starter motor on. The key
will return to the “ON” position when
released.
For starting tips, see page 474 in Section
3.
“ON”—Engine on and all accessories
on.
This is the normal driving position.
“ACC”—Accessories such as the radio
operate, but the engine is off.
If you leave the engine switch in the
“ACC” or “LOCK” position and open the
driver ’s door, a buzzer will remind you to
remove the key. “LOCK”—Engine is off and the steering
wheel is locked. The key can be re-
moved only at this position.
You must push in the key to turn the
engine switch from “ACC” to the “LOCK”
position. The selector lever must be put
in the “P” position before pushing the key.
Vehicles with engine immobilizer system—
Once you remove the key, the engine im-
mobilizer system is automatically set. (See
“Engine immobilizer system” on page 21
in Section 1−
2.)
When starting the engine, the engine
switch may seem stuck at the “LOCK”
position. To free it, first be sure the key
is pushed all the way in, and then rock
the steering wheel slightly while turning
the key gently.
Approximately five hours after the engine
is turned off, you may hear sound coming
from underneath the deck for several min-
utes. This is normal operation and does
not indicate a malfunction. (See “Leak
detection pump” on page x.)
It is not a malfunction if the needles on
all meters and gauges move slightly when
the engine switch is turned to the “ACC”,
“ON” or “START” position.
NOTICE
Do not leave the engine switch in the
“ON” position if the engine is not
running. The battery will discharge
and the ignition could be damaged.

Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic ignition
system/distributor ignition system
or fuel systems could cause an ex-
tremely high threeway catalytic
converter temperature.
 If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a checkup as soon
as possible. Remember, your Toyota
dealer knows your vehicle and its
threeway catalytic converter sys-
tem best.
 To ensure that the threeway
catalytic converter and the entire
emission control system operate
properly, your vehicle must receive
the periodic inspections required by
the Toyota Maintenance Schedule.
For scheduled maintenance
information, refer to the “Scheduled
Maintenance Guide” or “Owner’s
Manual Supplement”.CAUTION
Exhaust gases include harmful car-
bon monoxide (CO) that is colorless
and odorless. Inhaling exhaust
gases may lead to death or a seri-
ous health hazard.
The exhaust should be checked
occasionally. If there is a hole or
crack caused by corrosion, damage
to a joint or abnormal exhaust
noise, be sure to have the vehicle
inspected and repaired by your
Toyota dealer. Failure to do so may
allow exhaust gases to enter the
vehicle, resulting in death or a
serious health hazard.
If the vehicle is in a poorly venti-
lated area, turn the engine off. In a
closed area, such as a garage, ex-
haust gases may collect and enter
the vehicle. This may lead to death
or a serious health hazard.
Do not remain for a long time in a
parked vehicle with the engine run-
ning. If it is unavoidable, however,
do so only in an unconfined area
and adjust the heating or cooling
system to force outside air into the
vehicle.
Keep the back window closed while
driving. An open or unsealed back
window may cause exhaust gases
to be drawn into the vehicle.
To allow proper operation of your
vehicle’s ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, or oth-
er obstructions.
If the smell of exhaust is noticed
inside the vehicle, open the win-
dows. Large amounts of exhaust in
the vehicle can cause driver drowsi-
ness and an accident, resulting in
death or a serious health hazard.
Have the vehicle inspected by your
Toyota dealer immediately.
Engine exhaust cautions

544
2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
CAUTION
When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
Right after driving, the engine
compartment—the engine, radiator,
exhaust manifold, power steering
fluid reservoir and spark plug
boots, etc.—will be hot. So be care-
ful not to touch them. Oil, fluids
and spark plugs may also be hot.
If the engine is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.
Do not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
NOTICE
Remember that battery and ignition
coil carry high currents or voltages.
Be careful of accidentally causing a
short circuit.
 Add only “Toyota Super Long Life
Coolant” or similar high quality eth-
ylene glycol based nonsilicate,
nonamine, nonnitrite, and nonbo-
rate coolant with longlife hybrid
organic acid technology to fill the
radiator. “Toyota Super Long Life
Coolant” is a mixture of 50% cool-
ant and 50% deionized water (for
the U.S.A.) or 55% coolant and 45%
deionized water (for Canada).
 If you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging the parts
or paint.
 Do not allow dirt or anything else
to fall through the spark plug holes.
 Use only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
