CAUTION
■Roof luggage carrier precautions
When you load cargo on the roof luggage carrier, observe the following:
●Place the cargo so that its weight is distributed evenly between the
front and rear axles.
●If loading long or wide cargo, never exceed the vehicle overall length
or width. (P. 542)
●Before driving, make sure the cargo is securely fastened on the roof
luggage carrier.
●Loading cargo on the r oof luggage carrier will make the center of the
vehicle gravity higher. Avoid high speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers, otherwise it may result in loss of
control or vehicle rollover due to failure to operate this vehicle correctly
and result in death or serious injury.
●If driving for a long distance, on rough roads, or at high speeds, stop
the vehicle now and then during the trip to make sure the cargo
remains in its place.
●Do not exceed 150 lb. (68 kg) cargo weight on the roof luggage carrier.
■Cross rail adjustment
Make sure the cross rails are locked securely by pushing forward and
rearward them.
Failure to do so may cause an unexpected accident or severe injury in
the event of emergency braking or a collision.
NOTICE
■When loading the luggage
Be careful not to scratch the surface of the moon roof.

When driving
Trailer towing
Your vehicle is designed primarily as a passenger-carrying vehicle.
Towing a trailer will have an adverse effect on handling, perfor-
mance, braking, durability, and fu el consumption. For your safety
and the safety of others , do not overload the vehicle or trailer.
Toyota warranties do not apply to damage or malfunction caused by
towing a trailer for commercial purposes.
■ Weight limits
Confirm that the total trailer weight, gross vehicle weight, gross
axle weight and trailer tongue load are all within the limits.
■ Gross vehicle weight
The gross vehicle weight must not exceed the Gross Vehicle
Weight Rating (GVWR) indicated on the Certification Label. The
gross vehicle weight is the sum weight of the unloaded vehicle,
driver, passengers, luggage, hitch and trailer tongue load. Also
included is the weight of any sp ecial equipment installed on your
vehicle.
■ Gross axle weight
The load on either the front or rear axle resulting from distribu-

■ Trailer tongue load
The trailer cargo load should be distributed so that the tongue
load is 9 to 11% for weight carrying hitch or 15% for weight dis-
tributing hitch of the total trailer weight, not exceeding the maxi-
mum load of the following. (Tongue load / Total trailer weight x
100 = 9 to 11% or 15%)
Without towing package: 120 lb. (54 kg)
With towing package: 350 lb. (158 kg)
The total trailer weight and tongue load can be measured with

Hitch
Trailer hitch assemblies have different weight capacities established
by the hitch manufacturer. Even th ough the vehicle may be rated for
towing a higher weight, the operat or must never exceed the maxi-
mum weight rating specified for the trailer hitch.
■ Before towing
●Ensure that your vehicle’s tires are properly inflated. ( P. 463)
● Trailer tires should be inflated according to the trailer manufacturer's rec-
ommendation.
● All trailer lights must work in order to be legal.
● Confirm all lights work each time you connect them.
● Check that your vehicle remains level when a loaded or unloaded trailer
is hitched. Do not drive if the vehicle is not level, and check for improper
tongue load, overloading, worn suspension, or other possible causes.
● Make sure the trailer cargo is securely loaded.
● Check that your rear view mirrors c onform to any federal, state/provincial
or local regulations. If they do not, inst all rear view mirrors appropriate for
towing purposes.
■ Break-in schedule
Toyota recommends that you do not use a new vehicle or a vehicle with any
new power train components (engine, transmission, differential, wheel bear-
ings, etc.) to tow a trailer for the first 500 miles (800 km) of driving.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. (See “Scheduled Maintenance Guide” or
“Owner's Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km) of trailer towing.

232 2-5. Driving information
CAUTION
■To avoid accident or injury
●Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue load capacities.
● Never load more weight in the back than in the front of the trailer. About
60% of the load should be in the front half of the trailer, and the remaining
40% in the rear.
● Do not use cruise control when you are towing.
● Do not tow the vehicle with the compact spare tire installed.
■ Hitches
●Use only a hitch that conforms to the total trailer weight requirement.
● Follow the directions supplied by the hitch manufacturer.
● Lubricate the hitch ball with a light coat of grease.
● Remove the trailer hitch whenever you are not towing a trailer. After
removing the hitch, seal any mounting hole in the vehicle body to prevent
entry of any substances into the vehicle.
■ When towing a trailer
●If the gross trailer weight exceeds 1000 lb. (453 kg), trailer brakes are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle's hydraulic system, as this will lower the vehi-
cle's braking effectiveness.
● Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is danger of the trailer wandering into another lane.
