WARNING
■When inspecting or replacing tires 
Observe the following precautions to prevent accidents. 
Failure to do so may cause damage to parts of the drive train as well as 
dangerous handling characteristics, which may lead to an accident resulting 
in death or serious injury. 
● Do not mix tires of different makes, models or tread patterns. 
Also, do not mix tires of remarkably different treadwear. 
● Do not use tire sizes other than those recommended by Toyota. 
● Do not mix differently constructed tires (radial, bias-belted or bias-ply 
tires). 
● Do not mix summer, all season and snow tires. 
● Do not use tires that have been used on another vehicle. 
Do not use tires if you do not know how they were used previously.  
● Vehicles with a compact spare tire: Do not tow if your vehicle has a com- 
pact spare tire installed. 
● Vehicles with an emergency tire puncture repair kit: Do not tow anything if 
a tire that has been repaired using the emergency tire puncture repair kit is
installed. The load on the tire may cause unexpected damage to the tire. 
■ When initializing the tire pressure warning system (if equipped) 
Do not operate the tire pressure warning reset switch without first adjusting 
the tire inflation pressure to the specified level. Otherwise, the tire pressure 
warning light may not come on even if the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.

If your vehicle needs to be towed
The following may indicate a problem with your transmission. Contact 
any authorized Toyota retailer or Toyota authorized repairer, or any 
reliable repairer or commercial towing service before towing. 
● The engine is running but the vehicle does not move. 
● The vehicle makes an abnormal sound. 
Do not tow with a sling-type truck 
to prevent body damage.
If towing is necessary, we recommend having your vehicle 
towed by any authorized Toyota retailer or Toyota authorized 
repairer, or any reliable repairer or commercial towing service, 
using a wheel-lift type truck or flatbed truck.
Use a safety chain system for all towing, and abide by all state/ 
provincial and local laws.

If your vehicle is transported by a 
flatbed truck, it should be tied 
down at the locations shown in the 
illustration. 
If 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 dam- 
aged.

If a tow truck is not available in an emergency, your vehicle may be 
temporarily towed using cables or chains secured to the emergency 
towing eyelets. This should only be attempted on hard surfaced roads 
for at most 80 km (50 miles) at under 30 km/h (18 mph).  
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. 
Take out the towing eyelet. ( P. 429, 443) 
Push the lower left of the eyelet 
cover and then open it. 
Insert the towing eyelet into the 
hole and tighten partially by 
hand. 
Tighten down the towing eyelet 
securely using a wheel bolt 
wrench or hard metal bar.
To prevent damaging the front 
bumper, wrap the wheel bolt 
wrench with a rag as shown in the
illustration.

not function, making steering and braking more difficult.

compartment. ( P. 429, 443)
