5-1. Essential information
If your vehicle needs to be towed
Before towingThe following may indicate a problem with your transmission. Co ntact
your Toyota dealer before towing.
● The engine is running, but t he vehicle will not move.
● The vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available in an emergency, your vehicle m ay be
temporarily towed using a cable or chain secured to the emergen cy
towing eyelet. This should only be attempted on hard surfaced r oads
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.
For vehicles with an automatic transmission, only the front towing
eyelet may be used.
If towing is necessary, we recommend having your vehicle towed by
your Toyota dealer or a commerci al towing service, using a lift-type
truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all stat e/pro-
vincial and local laws.
If towing from the rear, the vehicle's front wheels and axles m ust be
in good condition. ( P. 391)
If they are damaged, use a to wing dolly or flat bed truck.

386 5-1. Essential information
To w i n g e y e l e t
■Before emergency towing
Release the parking brake.
Shift the shift lever to N.
Vehicles without a smart key system: Turn the engine switch to the
“ACC” (engine off) or “ON” (engine running) position.
Vehicles with a smart key system: Turn the “ENGINE START
STOP” switch to ACCESSORY (engine off) or IGNITION ON
(engine running) mode.
■ If towing a vehicle
Do not tow another vehicle. If towing a vehicle that has broken down is
unavoidable, avoid towing a vehicle that is heavier than your v ehicle. Also,
do not pull out a vehicle that has fallen into a ditch.
WARNING
■ 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 eyelets and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing .
● If the engine is not running, the power assist for the brakes a nd steering
will not function, making steering and braking more difficult.
