When driving
Example of follow-up cruising (when following a vehicle driving
slower than the set speed):
When the speed is set to 62 mph (100 km/h) and the vehicle ahead
is driving at 50 mph (80 km/h)
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration (when there are no longer vehicles driving
slower than the set speed in the lane ahead):
When the speed is set to 62 mph (100 km/h) and the vehicle ahead
driving at 50 mph (80 km/h) is out of the lane
When the vehicle ahead of you executes a lane change, the system
slowly accelerates until the set vehicle speed is reached. The system then
returns to fixed speed cruising.
■Fine adjustment of the set speed
Adjustment of the set speed by the following speed can be made by lightly
pressing the lever up or down and releasing it.
In the constant speed control mode: Approximately 1.0 mph (1.6 km/h)
In the vehicle-to-vehicle distance control mode:
U.S.A.: Approximately 5 mph (8 km/h)
Canada and Mexico: Approximately 5 km/h (3 mph)

Cargo and luggage
Adjusting the position of cross rails (if equipped)Turn the knobs counterclockwise
to release the cross rails.
Take notice of the following information about storage precau-
tions, cargo capacity and load.
●Stow cargo and luggage in the luggage compartment whenever
possible. Be sure all items are secured in place.
● Be careful to keep the vehicle level. Placing the weight as far for-
ward as possible helps maintain vehicle balance.
● For better fuel economy, do no t carry unnecessary weight.

Cross rails
STEP1

220 2-5. Driving information
Slide the cross rails to the appro-
priate position for loading lug-
gage and turn the knobs
clockwise to tighten the cross
rails securely.
Capacity and distributionCargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) - (Total weight of occupants)
Steps for Determining Correct Load Limit 
(1) Locate the statement “The co mbined weight of occupants and
cargo should never exceed XXX kg or XXX lbs.” on your vehi-
cle’s placard.
(2) Determine the combined weight of the driver and passengers that will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will
be five 150 lb passengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is 650 lbs. (1400 - 750 (5 
150) = 650 lbs.)
(5) Determine the combined wei ght of luggage and cargo being
loaded on the vehicle. That weig ht may not safely exceed the
available cargo and luggage load capacity calculated in Step 4.

When driving
CAUTION
■Storage precautions
Observe the following precautions.
Failing to do so may result in death or serious injury.
●
Do not place cargo or luggage in or on the following locations as the
item may get under the brake or accelerator pedal and prevent the
pedals from being depressed properly,
block the driver’s vision, or hit
the driver or passengers, causing an accident.
• Driver’s feet
• Front passenger or rear seats (when stacking items)
• Instrument panel
• Dashboard
●Secure all items in the occupant compartment, as they may shift and
injure someone during an accident or sudden braking.
●Never allow anyone to ride in the luggage compartment. It is not
designed for passengers. They should ride in their seats with their seat
belts properly fastened. Otherwise, they are much more likely to suffer
death or serious bodily injury, in the event of sudden braking or an
accident.
■Capacity and distribution
●Do not exceed the maximum axle weight rating or the total vehicle
weight rating.
●Even if the total load of occupant's weight and the cargo load is less
than the total load capacity, do not apply the load unevenly.
Improper loading may cause deterioration of steering or braking con-
trol which may cause death or serious injury.

224 2-5. Driving information
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
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.
