When trouble arises

5-1. Essential information
If your vehicle needs to be towed
Before towingThe 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 be 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.
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 to wing, and abide by all state/pro-
vincial and local laws.
If towing from the rear, the vehic le's front wheels and axles must be
in good condition. (→P. 313)
If they are damaged, use a towing dolly or flat bed truck.

308 5-1. Essential information
Towing eyelet
■Before emergency towing
Release the parking brake.
Shift the shift lever to N.
Turn the engine switch to the “ACC” (engine off) or “ON” (engine
running) position.
■ 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 vehicle. 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 and steering
will not function, making steering and braking more difficult.

314 5-1. Essential information
Using a flat bed truckIf you use chains or cables to tie
down your vehicle, the angles
shaded in black must be 45°.
Do not overly tighten the tie
downs or the vehicle may be
damaged.
NOTICE
■To prevent causing serious damage to the transmission when towing
using a wheel-lift type truck (vehicles with an automatic transmission)
Never tow this vehicle from the front with the rear wheels on the ground.
■ To prevent damaging the vehicle
●Do not tow the vehicle from the rear when the engine switch is in the
“LOCK” position or the key is removed. The steering lock mechanism is
not strong enough to hold the front wheels straight.
● When raising the vehicle from the rear, 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 from the rear.
