When driving
4RUNNER_U
CAUTION
■
When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever
or depress the accelerator pedal, this could cause an accident or fire due to
engine overheating. Additionally, if the vehicle is parked in a poorly venti-
lated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
● If the power brake assist function does not operate, do not follow other
vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase.
If this happens, do not continue to drive the vehicle. Have your brakes
fixed immediately.

■If the engine does not start
The engine immobilizer system may not have been deactivated. ( P. 113)
■ Steering lock
After turning the “ENGINE START STOP” switch off and opening and closing
the doors, the steering wheel will be locked due to the steering lock function.
Operating the “ENGINE START STOP” switch again automatically cancels
the steering lock.
■ When the steering lock cannot be released
■ Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.
■ When the “ENGINE START STOP” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately.
■ If the electronic key battery is depleted
 P. 557
The green indicator light on the “ENGINE
START STOP” switch will flash. Press the
“ENGINE START STOP” switch again

Fully release the parking brake.
Driving the vehicle with the parking brake set will lead to brake components
overheating, which may affect braking performance and increase brake
wear.
To set the parking brake, fully
depress the parking brake
pedal with your left foot while
depressing the brake pedal
with your right foot.
(Depressing the pedal again
releases the parking brake.)

slightly unless the control dial is turned fully upward.
NOTICE
■ To prevent damage to the engine and its components
● Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( P. 631)
■ While driving (Optitron type meter)
When the voltmeter indicates more than 19 V or less than 9 V, the battery
may be malfunctioning. Have your vehicle checked at your Toyota dealer.

4RUNNER_U
■Multi-terrain Select is temporarily canceled when
The front-wheel drive control lever or switch is shifted to H4 when Multi-ter-
rain Select is in ROCK, MOGUL or LOOSE ROCK mode. The mode indica-
tor will flash until the lever is shifted back to L4.
■ If the Multi-terrain Select indicator continues to flash
This may indicate a malfunction in the Multi-terrain Select system.
In this case, Multi-terrain Select is automatically canceled. Have your vehicle
inspected by your Toyota dealer.
■ If the Multi-terrain Select indicator goes off while Multi-terrain Select is
operating
● One of the vehicle systems related to Multi-terrain Select may be mal-
functioning.
Have your vehicle inspected by your Toyota dealer.
●
The brake actuator may be at risk of overheating.
A buzzer will sound, the “A-TRAC” indicator will go off and the “TRAC
OFF” indicator will come on. Stop the vehicle in a safe place. Refrain
from using Multi-terrain Select until the “A-TRAC” indicator comes back
on and the “TRAC OFF” indicator goes off. (The vehicle can still be
driven, even if Multi-terrain Select is inoperative.)
In the above cases, Multi-terrain Select is automatically canceled.

306 2-5. Driving information
4RUNNER_U●
Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before mak-
ing 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 c an destabilize the trailer.
● Take care when passing other v ehicles. Passing requires consider-
able distance. After passing a vehi cle, 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 temper atures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immediately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.

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 physically chal-
lenged
• 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.
● Do not use the seat heater more than necessary. Doing so may cause
minor burns or overheating.
NOTICE
■To prevent seat heater damage
Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.
■ To prevent battery discharge
Turn the seat heaters off when the engine is not running.

632 5-2. Steps to take in an emergency
4RUNNER_U
■Overheating
If you observe the following, your vehicle may be overheating:
● The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
● Steam comes out from under the hood.
CAUTION
■To prevent an accident or injury when inspecting under the hood of
your vehicle
● If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injuries such as burns.
● Keep hands and clothing away from the fan and drive belt while the engine
is running.
● Do not loosen the radiator cap, or coolant reservoir cap while the engine
and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable. ( P. 643)
Have the vehicle inspected at the nearest Toyota dealer as soon as
possible.
