581-1. For safe use
HILUX_OM_OM0K321E_(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.

1021-3. Emergency assistance
HILUX_OM_OM0K321E_(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.
● 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.
The service life of the backup battery does not exceed 3 years.
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.

rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.

Driving
HILUX_OM_OM0K321E_(EE)
■When starting off on an uphill (vehicles with hill-start assist control sys-
tem)
The hill-start assist control will activate. ( P. 422)
■ Driving in the rain
● Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
● Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.
■ Engine speed while driving (automatic transmission)
In the following conditions, the engine speed may become high while driving.
This is due to automatic up-shifting c ontrol or down-shifting implementation to
meet driving conditions. It does not indicate sudden acceleration.
● The vehicle is judged to be driving uphill or downhill
● When the accelerator pedal is released
■ Restraining the engine output (Brake Override System)
● When the accelerator and brake pedals are depressed at the same time, the
engine output may be restrained.
● Vehicles without multi-information display: A warning light comes on while
the system is operating. ( P. 637)
● Vehicles with multi-information display: A warning message is displayed on
the multi-information display while the system is operating. ( P. 645)
■ Breaking in your new Toyota
To extend the life of the vehicle, observing the following precautions is recom-
mended:
● For the first 300 km (200 miles):
Avoid sudden stops.
● For the first 800 km (500 miles) (models for model code destination W*):
Do not tow a trailer. ( P. 269)
*: See “Checking your vehicle’s model” if you are not sure of which model
your vehicle is. ( P. 1 2 )
● For the first 1000 km (600 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
• Do not drive slowly with the manual transmission in a high gear.

2604-1. Before driving
HILUX_OM_OM0K321E_(EE)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When driving the vehicle
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 2 9 4 )
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.
● On vehicles with manual transmission, observe the following to prevent
the clutch from being damaged.
• Do not operate the clutch halfway for a long period of time unless it is
necessary.
• Do not operate the clutch half or partial engaged to control the vehicle
speed, such as to drive the vehicle at a low speed, to hold the vehicle
on a slope, etc.
• Do not depress the brake pedal during operating the clutch half or par-
tial engaged.
Doing so could not only speed up the clutch wear, but also damage the
clutch or even cause a fatal accident such as vehicle fire.
■ When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
● Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid.
● After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.
