If your vehicle needs to be towed
Before towingThe following may indicate a problem with your transmission. Contact
your Toyota dealer before towing.
l The engine is running, but the vehicle will not move.
l 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 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 front, the vehic le's rear wheels and axles must be
in good condition. (→ P. 312)
If they are damaged, use a towing dolly or flat bed truck.

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
n Caution while towing
lUse 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.
l If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.
NOTICE
nTo prevent causing serious dama ge to the transmission
(vehicles with an automatic transmission)

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
nTo 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
nTo prevent causing serious da mage to the transmission
(vehicles with an automatic transmission)
Never tow this vehicle from the rear with the front wheels on the ground.
n To prevent damaging the vehicle (vehicles with a manual transmission)
lDo not tow the vehicle with the key removed or in the LOCK position.

If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and re sult in death or serious injury.
lStop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
lIf the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is pr obable that you have a flat tire. Check the tires.
If the tire is flat, change to the spare tire and have the flat tire repaired
by the nearest Toyota dealer.
lAvoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
nIf a blowout or sudden air leakage should occur
The tire pressure warning syste m may not activate immediately.
nMaintenance of the tire
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pr essure for those tires.)
