■ Outside temperature display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change:
● When the vehicle is stopped, or moving at low speeds (less than 20 km/h
[12 mph])
● When the outside temperature has changed suddenly (at the entrance/exit
of a garage, tunnel, etc.)
■ When “--” is displayed
The system may be malfunctioning. Take your vehicle to any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
■ The information display at low temperatures (vehicles with multi-infor-
mation display type B)
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the display monitor may
respond slowly, and display changes may be delayed.
For vehicles with automatic transmission: For example, there is a lag
between the driver’s shifting and the new gear number appearing on the
display. This lag could cause the driver to downshift again, causing rapid
and excessive engine braking and possibly an accident resulting in death or
injury.
NOTICE
■ To prevent damage to the engine and its components
● Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( P. 678)
■ The information display at low temperatures (vehicles with multi-infor-
mation display type A)
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the display monitor may
respond slowly, and display changes may be delayed.

2724-1. Before driving
HILUX_OM_OM0K321E_(EE)
■Important points regarding stability
Vehicle movement resulting from uneven road surfaces and strong
crosswinds will affect handling. The vehicle may also be rocked by
passing buses or large trucks. Frequently check behind when mov-
ing alongside such vehicles. As soon as such vehicle movement
occurs, immediately start to decelerate smoothly by slowly applying
the brakes. Always steer the vehicle straight ahead while braking.
■Passing other vehicles
Consider the total combined length of your vehicle and trailer and
ensure that the vehicle-to-vehicle distance is sufficient before exe-
cuting lane changes.
■Transmission information
Vehicles with manual transmission: To maintain engine braking effi-
ciency when using engine braking, do not use 5th gear and 6th
gear.
Vehicles with automatic transmission: To maintain engine braking
efficiency when using engine braking, do not use the transmission
in D. Transmission shift range position must be in 4 or lower, in S
mode.
■If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures
exceeding 30 C (85F) may result in the engine overheating. If the
engine coolant temperature gauge indicates that the engine is over-
heating, turn the air conditioning off immediately, leave the road and
stop the vehicle in a safe place. ( P. 678)
■When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle
and trailer. Firmly set the parking brake and shift the shift lever to P
for automatic transmissions, and 1 or R for manual transmissions.

load is large, the battery fluid temperature is excessively low or the bat-
tery has deteriorated.
• The brake booster vacuum is low.
• The vehicle is stopped on a steep incline.
• The steering wheel is being operated
• Due to traffic or other circumstances the vehicle is being stopped repeat-
edly.
• The vehicle is being driven in a high altitude area.
• Engine coolant temperature or tr ansmission fluid temperature is
extremely low or high.

Press the DPF system switch.
Vehicles without multi-information display
The DPF system warning light will change from solid to slow flashing, and
the idling engine speed will increase.
Vehicles with multi-information display
The DPF system warning message
shown in the illustration appears
on the display, and the idling
engine speed will increase.
Regeneration will take around 30 - 40 minutes to complete.*2
When the DPF system warning light or the DPF system warning mes-
sage goes out, the idling engine speed will have finished returning to
normal.
The DPF system switch may not operate when the vehicle is higher
than 4000 m (13123 ft.) above sea level.
*1: Depending on the situation, it may be necessary to depress the accelera-
tor pedal until the engine speed is increased to 3000 rpm. If the engine
coolant temperature or exhaust gas tem perature is low, it may take a long
time to regenerate, or regeneration may be impossible.
*2: Time required for regeneration differs in accordance with the outside tem-
perature. Also, if the engine speed is still approximately 2000 rpm 10 min-
utes after pressing the DPF system switch, the exhaust gas temperature
may be low. In this case, depress the accelerator pedal to run the engine
at approximately 3000 rpm for a while.
When depressing the accelerator pedal, regeneration will be stopped. In
this case, restart regeneration.

Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.
