Driving
WA R N I N G
●Vehicles with a Multidrive: Be care-
ful not to shift the shift lever with the
accelerator pedal depressed. Shift- ing the shift lever to any positions
other than P or N may lead to unex-
pected rapid acceleration of the vehicle that may cause an accident
and result in death or serious injury.
■If you hear a squealing or scrap- ing noise (brake pad wear indica-
tors)
Have the front and rear brake pads checked at the same time and
replaced by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as
possible.
Rotor damage may result if the pads
are not replaced when needed.
It is dangerous to drive the vehicle
when the wear limits of the brake
pads and/or those of the brake discs are exceeded.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other
than P (Multidrive) or N, the vehicle may accelerate suddenly and unex-
pectedly, causing an accident.
●Vehicles with a Multidrive: 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.
●If the vehicle is stopped on an
incline, in order to prevent acci- dents caused by the vehicle rolling
forward or backward, always
depress the brake pedal and securely apply the parking brake as
needed.
●Avoid revving or racing the engine. Running the engine at high speed
while the vehicle is stopped may
cause the exhaust system to over- heat, which could result in a fire if
combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette
lighters, spray cans, or soft drink cans in the vehicle when it is in the
sun.
Doing so may result in the follow- ing:
• Gas may leak from a cigarette
lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and
plastic material of glasses to
deform or crack.
• Soft drink cans may fracture, caus-
ing the contents to spray over the interior of the vehicle, and may also
cause a short circuit in the vehicle’s
electrical components.
●Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a place such as the glove box or on
the floor, it may be lit accidentally
when luggage is loaded or the seat is adjusted, causing a fire.
●Do not attach adh esive discs to the windshield or windows. Do not
place containers such as air fresh-
eners on the instrument panel or dashboard. Adhesive discs or con-
tainers may act as lenses, causing
a fire in the vehicle.
●Do not leave a door or window
open if the curved glass is coated
with a metallized film such as a sil- ver-colored one. Reflected sunlight
may cause the glass to act as a
lens, causing a fire.

1504-1. Before driving
WA R N I N G
●Always apply the parking brake,
shift the shift lever to P (vehicles
with a Multidrive), stop the engine and lock the vehicle.
Do not leave the vehicle unat-
tended while the engine is running. If the vehicle is parked with the shift
lever in P but the parking brake is
not set, the vehicl e may start to
move, possibly leading to an acci- dent.
●Do not touch the exhaust pipes while the engine is running or
immediately after turning the engine
off. Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise,
if you accidentally move the shift lever
or depress the accelerator pedal, this 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, leading to death or
a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when
the brakes are wet, and this may cause one side of the vehicle to
brake differently than the other
side. Also, the parking brake may not securely hold the vehicle.
●If the brake booster device does not operate, do not follow other vehi-
cles closely and avoid hills or sharp
turns that require braking. In this case, braking is still possible,
but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will
increase. Have your brakes fixed
immediately.
●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.
●The brake system consists of 2 indi-vidual 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 the braking
distance will increase. Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively
when a driven wheel is up in the air,
or the vehicle is stuck in sand, mud, etc. This may damage the driveline
components or propel the vehicle for-
ward or backward, causing an acci- dent.
NOTICE
■When driving the vehicle (vehi-
cles with a Multidrive)
●Do not depress the accelerator and brake pedals at the same time dur-
ing driving, as this may restrain the
engine output.
●Do not use the accelerator pedal or
depress the accelerator and brake pedals at the same time to hold the
vehicle on a hill.
■When driving the vehicle (vehi-
cles with a manual transmission)
●Do not depress the accelerator and brake pedals at the same time dur-
ing driving, as this may restrain the
engine output.
●Do not shift gears unless the clutch
pedal is fully depressed. After shift- ing, do not release the clutch pedal
abruptly. Doing so may damage the
clutch, transmission and gears.

1524-1. Before driving
Cargo and luggage
Take notice of the following
information about storage pre-
cautions, cargo capacity and
load:
WA R N I N G
■Things that must not be carried
in the trunk
The following things may cause a fire if loaded in the trunk:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the ped- als from being depressed properly,
may block the driver’s vision, or may
result in items hitting the driver or passengers, possibly causing an acci-
dent.
●Stow cargo and luggage in the trunk
whenever possible.
●When you fold down the rear seats,
long items should not be placed
directly behind the front seats.
●Do not place cargo or luggage in or
on the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the package tray
• On the instrument panel
• On the dashboard
●Secure all items in the occupant compartment.
■Load and distribution
●Do not overload your vehicle.
●Do not apply loads unevenly.Improper loading may cause deteri-
oration of steering or braking con-
trol which may cause death or serious injury.

■Tire information
●Increase the tire inflation pressure to
20.0 kPa (0.2 kgf/cm2 or bar, 3 psi)
greater than the recommended value when towing. ( P.524)
●Increase the air pressure of the trailer tires in accordance with the total
trailer weight and according to the val-
ues recommended by the manufac- turer of your trailer.
■Trailer lights
Please consult any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer when installing
trailer lights, as in correct installation
may cause damage to the vehicle’s lights. Please take care to comply with
your state’s laws when installing trailer
lights.
■Break-in schedule
Toyota recommends that vehicles fitted with new power train components
should not be used for towing trailers for
the first 800 km (500 miles).
■Safety checks before towing
●Check that the maximum load limit for
the towing hitch/bracket hitch ball is not exceeded. Bear in mind that the
coupling weight of the trailer will add
to the load exerted on the vehicle. Also make sure that you will not be
towing a load that exceeds the maxi-
mum permissible axle capacity.
●Ensure that the trailer load is secure.
●Supplementary outside rear view mir-
rors should be added to the vehicle if
the traffic behind cannot be clearly seen with standard mirrors. Adjust the
extending arms of these mirrors on
both sides of the vehicle so that they always provide maximum visibility of
the road behind.
■Maintenance
●Maintenance must be performed more
frequently when using the vehicle for
towing due to the greater weight bur- den placed on the vehicle compared
to normal driving.
●Retighten all bolts securing the hitch-
ing ball and bracket after towing for
approximately 1000 km (600 miles).
NOTICE
■When the rear bumper strength- ening material is aluminum
Ensure the steel bracket part does not
come directly in contact with that area.
When steel and aluminum come into
contact, there is a reaction similar to corrosion, which will weaken the sec-
tion concerned and may result in
damage. Apply a rust inhibitor to parts that will come in contact when attach-
ing a steel bracket.

1564-1. Before driving
Your vehicle will handle differently
when towing a trailer. In order to
avoid accident, death or serious
injury, keep the fo llowing in mind
when towing:
■Checking connections
between trailer and lights
Stop the vehicle and check the
operation of the connection
between the trailer and lights after
driving for a brief period as well as
before starting off.
■Practicing driving with a cou-
pled trailer
 Get the feel for turning, stopping
and reversing with the trailer
coupled by practicing in an area
with no or light traffic.
 When reversing with a coupled
trailer, hold the section of the
steering wheel nearest to you
and rotate clockw ise to turn the
trailer left or counterclockwise to
turn it right. Always rotate a little
at a time to prevent steering
error. Have someone guide you
when reversing to lessen the risk
of an accident.
■Increasing vehicle-to-vehicle
distance
At a speed of 10 km/h (6 mph), the
distance to the vehicle running
ahead of you should be equivalent
to or greater than the combined
length of your vehicle and trailer.
Avoid sudden braking that may
cause skidding. Otherwise, the
vehicle may spin out of control. This
is especially true when driving on
wet or slippery road surfaces.
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in th e trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the tr ailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor-
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre-
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length

Driving
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut-
ing lane changes.
■Transmission information
Multidrive
To maintain engine braking effi-
ciency and charging system perfor-
mance when using engine braking,
do not use the transmission in D,
must be in M and select gear step 4
or lower. ( P. 1 6 5 )
Manual transmission
Refrain from driving in 6th gear to
maintain the effectiveness of
engine braking and to maintain
charging system performance.
■If the engine overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the engine overheating. If the
engine coolant temperature gauge
indicates that the engine is over-
heating, turn the air conditioning off
immediately, leave the road and
stop the vehicle in a safe place.
( P.518)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift lever to P
(Multidrive) and 1 or R (manual
transmission).
WA R N I N G
Follow all the instructions described in
this section. Failure to do so could
cause an accident resulting in death or serious injury.
■Trailer towing precautions
When towing, make sure that none of
the weight limits are exceeded.
( P.153)
■Vehicle speed in towing
Observe the legal maximum speeds
for trailer towing.
■Before descending hills or long
declines
Reduce speed and downshift. How-
ever, never downshift suddenly while
descending steep or long downhill grades.
■Operation of the brake pedal
Do not hold the brake pedal
depressed often or for long periods of
time. Doing so may result in the brake overheating or reduce braking effects.
■To avoid accident or injury
●Vehicles with a compact spare tire:
Do not tow a trailer when the com-
pact spare tire is installed on your vehicle.
●Vehicles with the emergency tire puncture repair kit: Do not tow a
trailer when the tire installed is
repaired with the emergency tire puncture repair kit.
●Do not use the following systems when trailer towing.
• Cruise control (if equipped)
• Dynamic radar cruise control (if
equipped)
• Dynamic radar cruise control with
full-speed range (if equipped)
