Driving
WARNING
●Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill. Using the brakes continuously may cause the brakes to overheat and
lose effectiveness. ( →P.164, 168)
●Do not adjust the positions of the
steering wheel, the seat, or the inside or outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
●Always check that all passengers’ arms, heads or other parts of their body are not outside the vehicle.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce your ability to control
the vehicle.
●Sudden acceleration, engine brak-
ing due to shifting, or changes in engine speed could cause the vehi-cle to skid.
●After driving through a puddle, lightly depress the brake pedal to
make sure that the brakes are func- tioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not func-tioning properly, steering control
may be affected.
■When shifting the shift lever
●Vehicles with a Multidrive: Do not let the vehicle roll backward while a forward driving position is selected,
or roll forward while the shift lever is in R.Doing so may cause the engine to
stall or lead to poor brake and steering performance, resulting in an accident or damage to the vehi-
cle.
●Vehicles with a Multidrive: Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmis- sion and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmis- sion and may result in a loss of vehicle control.
●Do not shift the shift lever to a driv-ing position while the vehicle is
moving backward. Doing so can damage the transmis-sion and may result in a loss of
vehicle control.
●Moving the shift lever to N while the
vehicle is moving will disengage the engine from the transmission. Engine braking is not available
when N is selected.
●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 brake pads checked 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.

4-1. Before driving
WARNING
■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 adhesive 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.
●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 vehicle 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.

Driving
WARNING
■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 during 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 during 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.
●Observe the following precautions.
Failure to do so may cause exces- sive premature wear or damage to the clutch, eventually making it diffi-
cult to accelerate and start off from a stop. Have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
• Do not rest your foot on the clutch pedal or depress it any time other than when shifting.
Doing so may cause clutch trouble.
• Do not use any gear other than the
1st gear when starting off and mov- ing forward.Doing so may damage the clutch.

NOTICE
• Do not use the clutch pedal to adjust vehicle speed. When stop-
ping the vehicle with the shift lever in a position other then N, make sure to fully depress the clutch
pedal and stop the vehicle using the brake.Doing so may damage the clutch.
• When stopping the vehicle with the shift lever in a position other than N,
make sure to fully depress the clutch pedal and stop the vehicle using the brakes.
●Do not shift the shift lever to R with-out the vehicle completely stopped.
Doing so may damage the clutch, transmission and gears.
■When parking the vehicle (vehi-cles with a Multidrive)
Always set the parking brake and shift
the shift lever to P. Failure to do so may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there
for an extended period of time. Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to
avoid damaging the wheels, under- side of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a
flat tire ( →P.379, 389)
■When encountering flooded
roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so
may cause the following serious dam- age to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle becomes flooded or stuck in mud or
sand, be sure to have any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer check
the following:
●Brake function
●Changes in the quantity and quality of the engine oil, transmission fluid,
clutch fluid, differential oil, etc.
●Lubricant condition for the bearings
and suspension joints (where possi- ble), and the function of all joints, bearings, etc.

Capacity), and permissible draw-
bar load before towing. (P. 4 1 0 )
Toyota recommends the use of the
Toyota hitch/bracket for your vehi-
cle. Other products of a suitable
nature and comparable quality may
also be used.
For vehicles where the towing
device blocks any of the lights or
license plate, the following shall be
observed:
Do not use towing devices that
cannot be easily removed or
repositioned.
Towing devices must be
removed or repositioned when
not in use.
■Total trailer weight and per-
missible drawbar load
Total trailer weight
Weight of the trailer itself plus the trailer
load should be within the maximum
towing capacity. Exceeding this weight is dangerous. (P.410)
When towing a trailer, use a friction
coupler or friction stabilizer (sway con-
trol device).
Permissible drawbar load
Allocate the trailer load so that the
drawbar load is greater than 25 kg
(55.1 lb.) or 4% of the towing capacity.
Do not let the drawbar load exceed the
indicated weight. (P.410)
■Information tag (manufac-
turer’s label)
Gross vehicle mass
The combined weight of the driver, pas-
sengers, luggage, towing hitch, total
curb mass and drawbar load should not
exceed the gross vehicle mass by more
than 100 kg (220.5 lb.). Exceeding this
weight is dangerous.
Maximum permissible rear axle
capacity
The weight borne by the rear axle
should not exceed the maximum per-
missible rear axle capacity by 15% or
more. Exceeding this weight is danger-
ous. The values for towing capacity
were derived from testing conducted at
sea level. Take note that engine output
and towing capacity will be reduced at
high altitudes.

Driving
■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.164)
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.405)
■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 (Multid-
rive) and 1 or R (manual transmis-
sion).
WARNING
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.
●Vehicles with a Dynamic radar cruise control: Do not use dynamic
radar cruise control when you are towing.
