●If the DPF system warning message “DPF full See owner’s manual”
appears on the multi-information display, follow the procedure
below to regenerate.
When regenerating the filter during driving the vehicle
To regenerate the filter, the following driving methods are recom-
mended.*1
• By driving continuously (for example, at around 60 km/h [37 mph]
for 20 to 30 minutes).
• By avoiding short trips, or by driving continuously (leaving the
engine running for long periods of time).
Check the engine is warmed up before driving the vehicle to regenerate
the filter. If the engine is cold, warm up the engine by driving the vehicle
downshifting to increase the engine speed.*2
The warning message will disappear on the multi-information display when
regeneration is complete. However, depending on the driving condition
such as heavy traffic, the amount of accumulated deposit increases and
the warning message may not disappear on the multi-information display.
If the warning message does not disappear on the multi-information dis-
play after driving, press the DPF system switch to manually regenerate the
filter.
Regeneration during driving cannot be performed when the vehicle is
higher than 4000 m (13124 ft.) above sea level.
*1: When driving, pay sufficient attention to weather, road conditions, ter-
rain and traffic conditions, and drive according to traffic laws.
*2: Depending on the situation, it may be necessary to downshift until the
engine speed is increased to 3000 rpm. If the engine coolant tempera-
ture or exhaust gas temperature is low, it may take a long time to
regenerate, or regeneration may be impossible.

When regenerating the filter by pressing the DPF system switch
Stop the vehicle in a safe place.
Shift the shift lever to P (automatic transmission) or N (manual
transmission), and firmly set the parking brake.
Do not stop the engine.
Also, make sure that there are no flammable materials near the exhaust
pipe. ( P. 368)
Check the engine is warmed up. If the engine is cold, warm up the engine
by depressing the accelerator pedal.*1
Press the DPF system switch.
The DPF system warning message
shown in the illustration appears
on the multi-information display,
and the idling engine speed will
increase.
Regeneration will take around 15 -
40 minutes to complete.*2
When the DPF system warning message disappears on the multi-
information display, the idling engine speed will have finished return-
ing 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 acceler-
ator pedal until the engine speed is increased to 3000 rpm. If the engine
coolant temperature or exhaust gas temperature 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
temperature. Also, if the engine speed is still approximately 2000 rpm
10 minutes after pressing the DPF system switch, the exhaust gas tem-
perature 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.

4807-2. Maintenance
HILUX_OM_OM0K789E_(EE)
■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Toyota retailers or Toyota authorized
repairers, or any reliable repairers. For repairs and services covered by your
warranty, please visit an authorized Toyota retailer or repairer, who will use
genuine Toyota parts in repairing any difficulties you may encounter. There
can also be advantages in utilizing authorized Toyota retailers or repairers for
non-warranty repairs and services, as members of the Toyota network will be
able to expertly assist you with any difficulties you may encounter.
Your Toyota retailer or Toyota authoriz ed repairer, or any reliable repairer will
perform all of the scheduled maintenance on your vehicle reliably and eco-
nomically due to their experience with Toyota vehicles.
■ Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
● Engine missing, stumbling or pinging
● Appreciable loss of power
● Strange engine noises
● A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
● Change in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked
immediately.)
● Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
● Vehicle pulls to one side when driven straight on a level road
● Strange noises related to suspension movement
● Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal,
pedal almost touches the floor, vehicle pulls to one side when braking
● Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as pos-
sible. Your vehicle may need adjustment or repair.
