Maintenance and care
Fuel filter (diesel engine only)
The water in the fuel filter needs to be drained in either of the follow-
ing situations:
• The “DRAIN WATER FROM FUEL FILTER” warning message is
shown on the multi-information display and a buzzer sounds.
(P. 525)
• 1WW-FHV engine only: Every 20000 km (12000 miles) or 12
months.
1AD-FTV and 2AD-FHV engines
You may drain the fuel filter yourself. However, as the operation is dif-
ficult, we recommend having it drained by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional. Even if you decide to drain it yourself, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
Vehicles without smart entry & start system:
Turn the engine switch to the “LOCK” position.
Vehicles with smart entry & start system:
Turn the “ENGINE START STOP” switch off.
Place a small tray under the drain plug to catch the water and
any fuel that comes out.
Turn the drain plug counterclock-
wise about 2 to 2 1/2 turns.

Maintenance and care
Initializing the tire pressure warning system (if equipped)
The tire pressure warning system must be initialized in the fol-
lowing circumstances:
When rotating front and rear tires which have different tire infla-
tion pressures
When the tire inflation pressure is changed such as when
changing traveling speed
When changing the tire size
When the tire pressure warning system is initialized, the current
tire inflation pressure is set as the benchmark pressure.
How to initialize the tire pressure warning system (if
equipped)
Park the vehicle in a safe place and turn the engine switch to
the “LOCK” position (vehicles without smart entry & start sys-
tem) or the “ENGINE START STOP” switch off (vehicles with
smart entry & start system).
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. (P. 621)
Make sure to adjust the tire pressure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
Turn the engine switch to the “ON” position (vehicles without
smart entry & start system) or the “ENGINE START STOP”
switch to IGNITION ON mode (vehicles with smart entry &
start system).
