When driving
●
Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before mak-
ing a turn.
● Note that when making a turn, th e trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a wider than normal turning radius.
● Slow down before making a turn, in cross winds, on wet or slippery
surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in
D.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the
brakes too frequently. This could cause the brakes to overheat and
result in reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temperatures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immedi ately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.

Maintenance and care
CAUTION
●
Do not touch the engine compartment when the electric cooling fans are
operating.
Vehicles without smart key system: The electric cooling fan may keep
rotating for about 3 minutes even after the engine switch is turned to the
“LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant
temperature is high. Be sure the engine switch is in the “LOCK” position
when working near the electric cooling fan or radiator grille.
Vehicles with smart key system: The electric cooling fan may keep rotating
for about 3 minutes even after the “POWER” switch is OFF.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant temper-
ature is high. Be sure the “POWER” switch is OFF when working near the
electric cooling fans or radiator grille.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
■ If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious pro\
blem.

508 4-3. Do-it-yourself maintenance
Radiator and condenserCheck the radiators and condens er, and clear away any foreign
objects.
If either of the above parts are ex tremely dirty or you are not sure of
their condition, have your vehicl e checked by your Toyota dealer.
CAUTION
■When the hybrid system is hot
Do not touch the radiators or condenser as they may be hot and cause seri-
ous injuries, such as burns.
■ When the electric cooling fan is operating
Do not touch the engine compartment.
Vehicles without smart key system: The electric cooling fans may keep rotat-
ing for about 3 minutes after the engine switch is turned to the “LOCK” posi-
tion.
With the engine switch in the “ON” position, the electric cooling fans may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. Be sure the engine switch is in the “LOCK” position when
working near the electric cooling fan or radiator grille.
Vehicles with smart key system: The electric cooling fan may keep rotating
for about 3 minutes after the “POWER” switch is OFF.
With the “POWER” switch in ON mode, the electric cooling fan may automat-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. Be sure the “POWER” switch is OFF when working near the electric
cooling fan or radiator grille.

5-2. Steps to take in an emergency
If your vehicle overheats
Correction procedures■ If the needle of the engine coolant temperature gauge enters
the red zone
Stop the vehicle in a safe place and turn off the air condition-
ing system.
Check to see if steam is coming out from the engine area.
If you see steam:
Stop the hybrid system. Carefully lift the hood after the
steam subsides and then restart the hybrid system.
If you do not see steam: Leave the hybrid system operating and carefully lift the
hood.
Check if the cooling fans are operating.
If the fans are operating: Wait until the engine coolant temperature gauge begins to
fall and then stop the hybrid system.
If the fans are not operating: Stop the hybrid system immediately and call your Toyota
dealer.
The following may indicate that your vehicle is overheating:
●The needle of the engine coolant temperature gauge enters the
red zone:
The engine may be overheating.
● “Hybrid System Overheat” is shown on the multi-information dis-
play:
The power control unit may be overheating.
Follow the correction procedure as described below.
