When driving
●
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 larger than normal turning radius.
● Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway . Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the stee ring or brakes, your vehicle and
trailer will stabilize.
● 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.
● Due to the added load of the trailer, your vehicle's hybrid system
may overheat on hot days (at temperatures over 85°F [30°C])
when driving up a long or steep grade. If the engine coolant tem-
perature gauge indicates overheati ng, immediately turn off the air
conditioning (if in use), pull your vehicle off the road and stop in a
safe spot. ( P. 523)

434 4-3. Do-it-yourself maintenance
Radiator and condenserCheck the radiators and condenser and clear 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.
Brake fluid
■ Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
If the level is low, take your vehi-
cle to a Toyota dealer as soon as
possible. Do not drive your vehi-
cle if the red brake system warn-
ing light is on. Call a Toyota
dealer for assistance.
CAUTION
■When the hybrid system is hot
Do not touch the radiators or condenser as they may be hot and may cause
burns.
■ When the electric cooling fan is operating
Do not touch the engine compartment.
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 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.

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 and carefully lift the hood.
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:
