431-1. For safe use
1
For safety and security
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls airbag deployment based on infor-
mation obtained from the sensors etc. shown in the system compo -
nents diagram above. This informat ion includes crash severity and
occupant information. As the airbags deploy, a chemical reactio n in
the inflators quickly fills the airbags with non-toxic gas to h elp restrain
the motion of t he occupants.
Front bench type seat: The SRS airbags are designed to protect the
driver and right front passenger, and they are not designed to protect
an occupant in the front c enter seating position.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhale.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases to enter the vehicle a nd may lead
to an accident caused by light-headedness, or may lead to death or a serious
health hazard.
■ Important points while driving
● Double Cab and CrewMax models: Keep the back window closed.
● Double Cab and CrewMax models: If you smell exhaust gases in th e vehi-
cle even when the back window is closed, open the windows and h ave the
vehicle inspected at your Toyota dealer as soon as possible.
● Toyota does not recommend occupying the rear cargo area when it is fitted
with a slide-in camper, camper shell or other type cover while the engine is
running. This caution applies to both driving and stopped or pa rked situa-
tions with the engine running. Particular care should be taken to prevent
exhaust gases from entering camper bodies, trailers or other enclosures
on or around your vehicle. If exhaust fumes are detected, open all win-
dows and thoroughly ventilate the area.
■ When parking
● If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the engine.
● Do not leave the vehicle with the engine on for a long time.
If such a situation cannot be avoided, park the vehicle in an o pen space
and ensure that exhaust fumes do not enter the vehicle interior .
● Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle.
■ Exhaust pipe
The exhaust system needs to be checked periodically. 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.

NOTICE
■Notice on fuel quality
● Do not use improper fuels. If improper fuels are used, the engi ne will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way ca talytic
converters causing the emission control system to malfunction.
● Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performan ce
problems.
● Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine k nocking, etc.) is
encountered after using a different type of fuel, discontinue the use of that
type of fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle’s paint.
