100 1-7. Safety information
CAUTION
nWhen installing a child restraint system
lEnsure that the belt and tab are securely locked and the seat belt is not
twisted.
l Push and pull the child restraint system from side to side and forward to be
sure it is secure.
l After securing a child restraint system, never adjust the seat.
l Follow all installation instructions provided by the child restraint system
manufacturer.
l When a child restraint system with a top tether strap is installed, do not
install the head restraint. The head restraint may interfere with the top
tether strap preventing secure installation of the child restraint system.
l Make sure to properly store the removed head restraint in a secure place
when you use the child restraint system on the rear seat.
n Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the
seat belt will not securely hold the child restraint system, which could cause
death or serious injury to the child or other passengers in the event of emer-
gency braking, sudden swerving or an accident.
n To correctly attach a child r estraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects
around the anchors and that the seat belt is not caught behind the child
restraint. Make sure the child restraint system is securely attached, or it may
cause death or serious injury to the child or other passengers in the event of
emergency braking, sudden swerving or an accident.

When driving
CAUTION
n
When driving on slippery road surfaces
lSudden changes in engine speed, such as engine braking caused by up-
shifting or down-shifting, may cause the vehicle to skid, resulting in an
accident.
l After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected, resulting in
an accident.
n When shifting the shift lever
Vehicles with an automatic transmission: Be careful not to shift the shift lever
with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident and result in death or serious injury.
n When the vehicle is stopped
lDo not race the engine.
If the vehicle is in any gear other than P (automatic transmission only) or
N, the vehicle may accelerate suddenly and unexpectedly, and may cause
an accident.
l Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
l Vehicles with an automatic transmission: In order to prevent accidents due
to the vehicle rolling away, always keep depressing the brake pedal while
the engine is running, and apply the parking brake as necessary.
l If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or ba ckward, always depress the brake pedal
and securely apply the parking brake as needed.
l Avoid revving or racing the engine. Running the engine at high speed
while the vehicle is stopped may cause the exhaust system to overheat,
which could result in a fire if combustible material is nearby.

When driving
CAUTION
n
When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift
lever or depress the accelerator pedal, which could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leadin\
g to
death or a serious health hazard.
n When braking the vehicle
lWhen the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one
side of the vehicle to brake differently than the other side. Also the parking
brake may not securely hold the vehicle.
l If the power brake assist function does not operate, do not follow other
vehicles closely and avoid downhills or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the
pedal than usual. Braking distance may also increase.
l Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
l The brake system consists of 2 individual hydraulic systems: If one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and braking distance
becomes longer.
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.

Cargo and luggage
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 vehicle’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 av ailable amount of cargo and lug-
gage 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 available
cargo and luggage load capacity is 650 lbs. (1400 − 750 (5 × 150)
= 650 lbs.)
(5) Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the
available cargo and luggage load capacity calculated in Step 4.
Take notice of the following information about storage precau-
tions, cargo capacity and load.
lStow cargo and luggage in the trunk whenever possible.
l Be sure all items are secured in place.
l Be careful to keep the vehicle level. Placing the weight as far for-
ward as possible helps maintain vehicle balance.
l For better fuel economy, do no t carry unnecessary weight.

148 2-5. Driving information
CAUTION
nThings that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk.
lReceptacles containing gasoline
lAerosol cans
nStorage precautions
Observe the following precautions.
Failing to do so may result in death or serious injury.
lDo not place cargo or luggage in or on the following locations as the
item may get under the clutch, 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)
• Package tray
• Instrument panel
• Dashboard
• Auxiliary box or tray that has no lid
lSecure all items in the occupant compartment, as they may shift and
injure someone during emergency braking, sudden swerving or an
accident.
lNever allow anyone to ride in the enlarged trunk. It is not designed for
passengers. They should ride in their seats with their seat belts prop-
erly fastened. Otherwise, they are much more likely to suffer death or
serious bodily injury, in the event of sudden braking, sudden swerving
or an accident.
nCapacity and distribution
lDo not exceed the maximum axle weight rating or the total vehicle
weight rating.
lEven 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 control which
may cause death or serious injury.

Towing a trailerConsult your Toyota dealer for further information about additional
requirements such as a towing kits, etc.
n Before towing
Check that the following conditions are met:
lEnsure that your vehicle’s tires are properly inflated. ( →P. 347)
l Trailer tires should be inflated according to the trailer manufacturer’s rec-
ommendation.
l All trailer lights work to be legal.
l Confirm all lights work each time you connect them.
l The trailer ball is set up at the proper height for the coupler on the t\
railer.
l 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.
l Make sure the trailer cargo is securely loaded.
l Check that your rear view mirrors conform to any federal, state/provincial
or local regulations. If they do not, install rear view mirrors appropriate for
towing purposes.
n 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.
n Maintenance
lIf 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”.)
l Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km).

When driving
CAUTION
n
To avoid accident or injury
lThe total trailer weight (trailer weight plus the weight of cargo) must not
exceed 700 lb. (318 kg)
l Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue load capacities.
l Do not tow the vehicle with the compact spare tire installed.
n Hitches
Trailer hitch assemblies have different weight capacities established by the
hitch manufacturer. Even though the vehicle may be rated for towing a
higher weight, the operator must never exceed the maximum weight rating
specified for the trailer hitch.
lIf you wish to install a trailer hitch, your Toyota dealer should be consulted.
l Use only a hitch that conforms to the total trailer weight requirement.
l Follow the directions supplied by the hitch manufacturer.
l Lubricate the hitch ball with a light coat of grease.
l Remove the trailer hitch whenever you are not towing a trailer to reduce
the possibility of additional damage caused by the hitch if your vehicle is
struck from behind.
n When towing a trailer
lNever tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’s braking effectiveness.
l 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.
