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. 293)
If they are damaged, use a towing dolly or flat bed truck.

5-2. Steps to take in an emergency
CAUTION
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installati
on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
nIf 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 result 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.
