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

■Locking the rear differential
The following systems do not operate w hen the rear differential is locked.
It is normal operation for the ABS warning light, VSC OFF indicator (if
equipped) and “TRC OFF” indicator (if equipped) to be on or for “TRC
TURNED OFF”/“TRC turned off” to be displayed on the multi-information dis-
play (if equipped) at this time.
•ABS
• Brake assist (if equipped)
• VSC (if equipped)
• TRC/A-TRC (if equipped)
• Trailer Sway Control (if equipped)
• Hill-start assist control (if equipped)
• Downhill assist control (if equipped)
■ Unlocking the rear differential
If the rear differential lock indicator still flashes even after unlocking the rear
differential, check the safety of the surrounding area and slightly turn the
steering wheel in either direction while the vehicle is in motion.
■ Automatic system cancelation of the rear differential lock system
The rear differential lock is also unlocked in any of the following situations:
● The front-wheel drive control switch is turned to H2 or H4 (4WD models)
● The engine switch is turned to the “ACC” or “LOCK” position (vehicles with-
out smart entry & start system) or A CCESSORY or off (vehicles with smart
entry & start system)
■ After unlocking the rear differential
Check that the indicator goes off.
WARNING
■ To avoid an accident
Failure to observe the following precautions may result in an accident.
● Do not use the rear differential lock system except when wheel spinning
occurs in a ditch or on a slippery or rugged surface. Large steering effort
and careful cornering control will be required.
● Do not lock the rear differential until the wheels have stopped spinning.
Otherwise, the vehicle may move in an unexpected direction when the dif-
ferential lock is engaged, resulting in an accident. This may also lead to
possible damage to rear differential lock component parts.
● Do not drive over 8 km/h (5 mph) when the differential is locked.

■ System malfunction
In the following cases, have your vehicle checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
● The downhill assist control system indicator does not come on when the
engine switch is turned to the “ON” position (vehicles without smart entry &
start system) or IGNITION ON mode (vehicles with smart entry & start sys-
tem).
● The downhill assist control system indicator does not come on when the
“DAC” switch is pressed.
● The slip indicator comes on.
WARNING
■When using downhill assist control system
● Do not rely overmuch on the downhill assist control system. This function
does not extend the vehicle’s performance limitations. Always thoroughly
check the road conditions, and drive safely.
● Vehicles with manual transmission: Drive in a low gear. Driving in a high
gear when using downhill assist control system may cause the engine to
stall, which may lose the brake effectiveness and lock the tires, resulting in
an accident.
● Vehicles with manual transmission: On a steep slope, use the engine brak-
ing efficiently. If the vehicle is driven in N or with the clutch pedal
depressed on a steep slope, the load on the brake increases and con-
trolling the vehicle speed may be impossible, resulting in an accident.
■ The system may not operate on the following surfaces, which may lead
to an accident causing death or serious injury
● Slippery surfaces such as wet or muddy roads
● Icy surface
● Unpaved roads

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.
