For safety and security
WARNING
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle. This could lead to an accident, resulting in
death or serious injury.
Q When installing the driver’s floor mat
O Do not use floor mats designed for other models or different model year
vehicles, even if they are Toyota Genuine floor mats.
O Only use floor mats designed for the driver’s seat.
O Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
O Do not use two or more floor mats on top of each other.
O Do not place the floor mat bottom-side up or upside-down.
Q Before driving
OCheck that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
O With the engine stopped and the shift
lever in P (automatic transmission) or N
(manual transmission), fully depress
each pedal to the floor to make sure it
does not interfere with the floor mat.

561-1. For safe use
HILUX_OM_OM0K513E_(EE)
Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhaled.
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 enter the vehicle and may lead to
an accident caused by light-headedness, or may lead to death or a serious
health hazard.
Q Important points while driving
If you smell exhaust gases in the vehicle, open the windows and have the
vehicle inspected at any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer as soon as possible.
Q When parking
O If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the engine.
O Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and ensure that exhaust fumes do not enter the vehicle interior.
O 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.
Q 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 any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.

1121-3. Emergency assistance
HILUX_OM_OM0K513E_(EE)
When the engine switch is turned to the “ON” position (vehicles with-
out smart entry & start system) or IGNITION ON mode (vehicles with

O If the green indicator light illuminates and stays on, the system is
enabled.
O If the green indicator light flashes twice per second, an automatic or
manual Emergency Call is being made.
O If no indicator lights illuminate, the system is not enabled.
O If the red indicator light illuminates at any time other than immedi-
ately after the engine switch is turned to the “ON” position (vehicles
without smart entry & start system) or IGNITION ON mode (vehi-
cles with smart entry & start system), the system may be malfunc-
tioning or the backup battery may be depleted. Contact any
authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.
O If the red indicator light blinks for approximately 30 seconds during
an Emergency Call, the call has been disconnected or the cellular
network signal is weak.
A test mode is provided for to check the performance of the Emer-
gency Call system. To test the device, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
