NOTICE
■When driving the vehicle
Vehicles 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.
Vehicles 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 shifting,
do not release the clutch pedal abruptly. Doing so may damage the clutch,
transmission and gears.
● Observe the following to prevent the clutch from being damaged.
• Do not rest your foot on the clutch pedal while driving.
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.
• Do not use the clutch to hold the vehicle when stopping on an uphill
grade.
Doing so may damage the clutch.
● Do not shift the shift lever to R when the vehicle is still moving. Doing so
may damage the clutch, transmission and gears.
■ When parking the vehicle (vehicles with a Multidrive)
Always 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.

NOTICE
■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, underside of the vehicle, etc.
● Diesel engine only: Make sure to idle the engine immediately after high-
speed driving or hill climbing. Stop the engine only after the turbocharger
has cooled down.
Failure to do so may cause damage to the turbocharger.
■ 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 vehi-
cle.
● 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. 445)
■ When encountering flooded roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so may
cause the following serious damage 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 is flooded, be
sure to have any authorized Toyota dealer or repairer or another duly quali-
fied and equipped professional check the following:
● Brake function
● Changes in quantity and quality of engine oil and transaxle fluid, etc.
● Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.

■Maximum permissible rear axle capacity
Vehicle category M1 models*
The weight borne by the rear axle should not exceed the maximum
permissible rear axle capacity by 15% or more. Exceeding this
weight is dangerous.
Vehicle category N1 models*
The weight borne by the rear axle should not exceed the maximum
permissible rear axle capacity. Exceeding this weight is dangerous.
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.
*: To distinguish the vehicle category, ask any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
WARNING
■ When the gross vehicle mass or maximum permissible axle capacity is
exceeded (vehicle category M1 models*)
Failing to observe this precaution may lead to an accident causing death or
serious injury.
● Add an additional 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) to the tire inflation
pressure.
● Do not exceed the established speed limit for towing a trailer in built-up
areas or 100 km/h (62 mph), whichever is lower.

1824-1. Before driving

■Sudden acceleration/steering input/cornering
Executing sharp turns when towing may result in the 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 trailer 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 normally 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. Frequently check behind when mov-
ing 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 of your vehicle and trailer and
ensure that the vehicle-to-vehicle distance is sufficient before exe-
cuting lane changes.
■Transmission information
Vehicles with a Multidrive
To maintain engine braking efficiency, when using engine braking,
do not use the transmission in D. Transmission shift gear position
must be in 4 in the M mode. ( P. 193)
Vehicles with a manual transmission
To maintain engine braking efficiency, when using engine braking,
do not use the transmission in 5 and 6 (vehicles with a 6-speed
manual transmission) gear. ( P. 198)

■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
high engine coolant temperature warning light flashes or comes on,
turn the air conditioning off immediately, leave the road and stop the
vehicle in a safe place. ( P. 485)
■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
for Multidrives or 1 or R for manual transmissions.
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. 176)
■ Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.
■ Before descending hills or long declines
Reduce speed and downshift. However, 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 cruise control: Do not use cruise control when you are tow-
ing.
● Vehicles with a compact spare tire: Do not tow a trailer when the compact
spare tire is installed on your vehicle.
● Vehicles with an emergency tire puncture repair kit: Do not tow a trailer
when the tire installed is repaired with the emergency tire puncture repair
kit.
