5-1. Essential information
If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission. Contact
your Toyota dealer before towing.
●The engine is running, but the vehicle will not move.
●The vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available, in an emergency your vehicle may be
temporarily towed using a cable or chain secured to the emergency
towing eyelet. This should only attempted on hard, surfaced roads for
short distances at low speeds.
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.
Towing eyelet
If towing is necessary, we recommend having your vehicle towed by
your Toyota dealer or a commercial towing service, using a lift-type
truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all state/pro-
vincial and local laws.
If towing from the front, the vehicle's rear wheels and axles must be
in good condition. (P. 308)
If they are damaged, use a towing dolly or flat bed truck.

306 5-1. Essential information
■Emergency towing procedure
Release the parking brake.
Put the transmission in N.
Turn the engine switch to the ACC (engine off) or ON (engine run-
ning) position.
CAUTION
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelet and the cables or chains. Always
use caution for the surroundings and other vehicles 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.
NOTICE
■To prevent causing serious damage to the transmission
(vehicles with an automatic transmission)
Never tow this vehicle from the rear with the front wheels on the ground.
This may cause serious damage to the transmission.
■When towing a vehicle without using a towing dolly
(vehicles with a manual transmission)
Do not tow with the key removed or in the LOCK position.

When trouble arises
309 5-1. Essential information
Towing with a wheel lift-type truck from the rear
Vehicles with an automatic trans-
mission: Use a towing dolly
under the front wheels.
Vehicles with a manual transmis-
sion: We recommend to use a
towing dolly under the front
wheels.
When not using a towing dolly,
turn the engine switch to the ACC
position and shift the shift lever to
N.
NOTICE
■To prevent damaging the vehicle
When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.
NOTICE
■To prevent causing serious damage to the transmission
(vehicles with an automatic transmission)
Never tow this vehicle from the rear with the front wheels on the ground.
■To prevent damaging the vehicle (vehicles with a manual transmission)
●Do not tow the vehicle with the key removed or in the LOCK position.
The steering lock mechanism is not strong enough to hold the front wheel
straight.
●When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.

5-1. Essential information
Event data recorder
In a crash or a near car crash event
The SRS airbag sensor assembly contains the EDR. In a crash or a
near car crash event, this device may record some or all of the follow-
ing information:
●Engine speed
●Whether the brake pedal was applied or not
●Vehicle speed
●To what extent the accelerator pedal was depressed
●Position of the transmission shift lever
●Whether the driver and front passenger wore seat belts or not
●Driver’s seat position
●SRS airbag deployment data
●SRS airbag system diagnostic data
●Front passenger’s occupant classification
The information above is intended to be used for the purpose of
improving vehicle safety performance. Unlike general data recorders,
the EDR does not record sound data such as conversation between
passengers.
Your vehicle has computers that monitor and control certain aspects
of your vehicle. These computers assist in driving and maintaining
optimal vehicle performance.
Besides storing data useful for troubleshooting, there is an event
data recorder (EDR) that records data in a crash or a near car
crash event.

316 5-2. Steps to take in an emergency

cle that may lead to an accident. Immediately stop the vehicle in a
safe place and contact your Toyota dealer.

to indicate low oil level, and the oil level must be checked using the engine

■Starting the engine when the battery is discharged (vehicles with an
automatic transmission)
The engine cannot be started by push-starting.
■Avoiding a discharged battery
●Turn off the headlights and the audio system while the engine is turned

●Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery.
●Make sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended termi-
nal.
●Do not allow the jumper cables to come into contact with the “+” and “-” ter-
minals.
●Do not smoke, use matches, cigarette lighters or allow open flame near
the battery.
