WARNING
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■ When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
In this case, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

DPF (Diesel Particulate Filter) system
◆Regeneration
Regeneration is performed as necessary in accordance with driving
conditions.
◆System characteristics
The DPF system has the following characteristics:
● Idle speed increases during regeneration
● The smell of the exhaust gas differs from that of a conventional
diesel vehicle
● White smoke may be emitted from the exhaust pipe during
regeneration. However, this does not indicate a malfunction.
● If the DPF system warning light turns on (vehicles without multi-
information display) or the DPF system warning message “DPF
FULL MANUAL REGENERATION REQUIRED SEE OWNER’S
MANUAL”/“DPF full Manual regeneration required See owner’s
manual” appears on the display (vehicles with multi-information dis-
play), follow the procedure below to regenerate.
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. 436)
Check the engine is warmed up. If the engine is cold, warm up the engine
by depressing the accelerator pedal.*1
: If equipped
When the deposit collected by the filter reaches a predetermined
amount, it is automatically regenerated.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
Perform the following according to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.
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.
