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.

Maintenance and care
■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.

The coolant level is satisfactory if it is between the “F” and “L” lines on
the reservoir when the engine is cold.
If the level is on or below the “L” line, add coolant up to the “F” line.
( P. 645)
■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non- nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -35 C [-31F])
For more details about engine coolant, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, drain cock
and water pump. If you cannot find a leak, have any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer test the cap and check
for leaks in the cooling system.
