When the engine is stopped by the Stop & Start system when the
vehicle is on an incline, when the brake pedal is released, brake force
is temporarily maintained to prevent the vehicle from rolling back-
wards before the engine is restarted and drive force is generated.
When drive force is generated, the maintained brake force is automat-
ically canceled.
● This function operates on flat surfaces as well as steep inclines.
● Sound may be generated from the brake system, but this does not
indicate a malfunction.
● Brake pedal response may change and vibration may occur, but
this does not indicate a malfunction.
■ Points for use
● If the engine switch is pressed when the engine is stopped by the Stop &
Start system, the engine will not be able to be restarted by the automatic
engine start function. In this case, restart the engine using the normal
engine starting procedure. ( P. 219, 222)
● When the engine is being restarted by the Stop & Start system, the power
outlets may be temporarily unusable, but this does not indicate a malfunc-
tion.
● Installation and removal of electrical components and wireless devices may
affect the Stop & Start system. Contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer for details.
● When stopping the vehicle for a longer period of time, turn the engine switch
to the “LOCK” position*1 or off*2 to stop the engine completely.
● When the engine is restarted by the Stop & Start system, the steering wheel
may temporarily feel heavy.
● 4WD models only: While driving in L4 mode, it is recommended that the
Stop & Start system be canceled because the system may not operate prop-
erly.

When trouble arises
If a tow truck is not available in an emergency, your vehicle may be
temporarily towed using cables or chains secured to the emergency
towing hooks. This should only be attempted on hard surfaced roads
for at most 80 km (50 miles) at under 30 km/h (18 mph).
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
Securely attach cables or
chains to the towing hooks.
Take care not to damage the vehi-
cle body.
Enter the vehicle being towed and start the engine.
If the engine does not start, turn the engine switch to the “ON” position
(vehicles without smart entry & start system) or IGNITION ON mode (vehi-
cles with smart entry & start system).
Vehicles with Stop & Start system:
Before towing the vehicle, turn the engine switch to the “LOCK” position
(vehicles without smart entry & start system) or off (vehicles with smart
entry & start system) once, and then start the engine.
4WD models: Turn the front-wheel drive control switch to H2.

■While towing
If the engine is not running, the power assist for the brakes and steering will
not function, making steering and braking more difficult.
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When towing the vehicle
■ While towing
● When towing using cables or chains, avoid sudden starts, etc. which place
excessive stress on the towing hooks, cables or chains. The towing hooks,
cables or chains may become damaged, broken debris may hit people,
and cause serious damage.
● Vehicles without smart entry & start system or vehicles with manual trans-
mission: Do not turn the engine swit ch to the “LOCK” position (vehicles
without smart entry & start system) or off (vehicles with smart entry & start
system).
There is a possibility that the steering wheel is locked and cannot be oper-
ated.
Pre Runner (2WD models): Be sure to
transport the vehicle with all four wheels
raised off the ground. If the vehicle is
towed with the tires contacting the
ground, the drivetrain and related parts
may be damaged or an accident may
occur due to a change in direction of the
vehicle.
4WD models: Be sure to transport the
vehicle with all four wheels raised off the
ground. If the vehicle is towed with the
tires contacting the ground, the drivetrain
and related parts may be damaged, and
the vehicle may fly off the truck.
