2-4. Using other
driving systems
2
When driving
■If the brake system overheats
TRAC or A-TRAC will cease operation, and the slip indicator will change
from flashing to being on continuously to alert the driver. Stop the vehicle in
a safe place. (There is no problem with continuing normal driving.)
■ Shifting to 4L position
The VSC OFF indicator will come on.
If the center differential is locked, VSC and Trailer Sway Control are auto-
matically turned off.
■ Power steering system operation sound
When you turn the engine switch to ON after the battery has been discon-
nected and reconnected, a sound may be heard from the engine compart-
ment.
This does not indicate a malfunction.
CAUTION
Any of the following conditions may result in an accident which could cause
death or serious injury.
■ The ABS does not opera te effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations.
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with pothol es or roads with uneven roads

2-5. Driving information
2
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 crosswinds, 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 use the transmission in
D.
Transmission shift range position must be in 4 in the S mode.
● 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.

Cigarette lighter
■The cigarette lighter can be used when
The engine switch is in the ACC or ON position.
CAUTION
■To avoid burns or fires
●Do not touch the metal parts of the cigarette lighter.

CAUTION
■Burns
●Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the disabled
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)
● Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
NOTICE
■To prevent seat heater damage
Do not put unevenly weighted objects on the seat and do not stick sharp
objects (needles, nails, etc.) into the seat.
■ To prevent battery discharge
Turn the switches off when the engine is not running.

If your vehicle overheats
Correction proceduresStop the vehicle in a safe place and turn off the air condition-
ing system, and then stop the engine.
If you see steam: Carefully lift the hood after the steam subsides.
If you do not see steam: Carefully lift the hood.
After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radia-
tor) for any leaks.

If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
The coolant level is satisfactory if
it is between the “FULL” and
“LOW” lines on the reservoir.Engine coolant reservoir
