561-1. For safe use
HILUX_OM_OM0K789E_(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.
■ 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.
■ 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 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.
● 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 any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.

1101-3. Emergency assistance
HILUX_OM_OM0K789E_(EE)
When the engine switch is turned to the “ON” position (vehicles with-
out smart entry & start system) or IGNITION ON mode (vehicles with
smart entry & start system), the red indicator light will illuminate for 10
seconds and then the green indicator light will illuminate, indicating
that the system is enabled. The indicator lights indicate the following:
● If the green indicator light illuminates and stays on, the system is
enabled.
● If the green indicator light flashes twice per second, an automatic or
manual Emergency Call is being made.
● If no indicator lights illuminate, the system is not enabled.
● 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. The backup battery
has lifespan of at least 3 years. Contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
● 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.

Driving
HILUX_OM_OM0K789E_(EE)
■ After driving on muddy roads in poor condition (for EURO VI models*
with 1GD-FTV and 2GD-FTV engines)
Check the cooling fins of the urea injector and clear away any foreign objects
or substances such as leaves or mud. If any of the above parts is extremely
dirty or you are not sure of their condition, have your vehicle inspected by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
*: EURO VI is an emission standard. If it is not clear that your vehicle meets
relevant standards, contact any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When starting the vehicle
On vehicles with automatic transmission, always keep your foot on the
brake pedal while stopped with the engine running. This prevents the vehi-
cle from creeping.
■ When driving the vehicle
● Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the
vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.
● During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. This will make it more difficult to
steer and brake, so you should pull over and stop the vehicle as soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 555
