■When adding fluid
Avoid overfilling, or the power steering may be damaged.
■ After replacing the reservoir cap
Check the steering box case, vane pump and hose connections for leaks or

■Before recharging
When recharging, the battery produces hydrogen gas which is flammable
and explosive. Therefore, before recharging:
●If recharging with the battery installed on the vehicle, be sure to discon-
nect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.

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 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.
Type A 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.
The wheels and axle on the groun d must be in good condition.
If they are damaged, use a towing dolly or flat bed truck.

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.

ing dolly under the front wheels.
When not using a towing dolly,
turn the engine switch to the ACC
position, shift the shift lever to N
and put the front wheel drive con-
trol switch in 2WD.
Using a flat bed truck
If your Toyota is transported by a
flat bed truck, it should be tied
down at the locations shown in
the illustration.
NOTICE
■To prevent damage to the vehicle
●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.
