WARNING
■If the vehicle becomes stuck (AWD models)
Do not spin the wheels excessively when any of the tires 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
●Do not depress the accelerator and
brake pedals at the same time during driving, as this may restrain the hybrid system 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 parking the vehicle
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.448, 459)

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 quantity and quality of
oil and fluid used for the engine, hybrid transmission, differential, etc.

4-1. Before driving
Driving
Check the allowable towing capac-
ity, GVM (Gross Vehicle Mass),
MPAC (Maximum Permissible Axle
Capacity), and permissible draw-
bar load before towing. ( P. 4 8 4 )
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 vehicle 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.484)
When towing a trailer, use a friction
coupler or friction stabilizer (sway con-
Trailer towing
Your vehicle is designed pri-
marily as a passenger carrying
vehicle. Towing a trailer will
have an adverse effect on han-
dling, performance, braking,
durability, and fuel consump-
tion. Your safety and satisfac-
tion depend on the proper use
of correct equipment and cau-
tious driving habits. For your
safety and the safety of others,
do not overload the vehicle or
trailer.
To tow a trailer safely, use
extreme care and drive the
vehicle in accordance with the
trailer’s characteristics and
operating conditions.
Toyota warranties do not apply
to damage or malfunction
caused by towing a trailer for
commercial purposes.
Contact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable
repairer for further information
about additional requirements
such as towing kits, etc.

■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.490)
●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 incorrect installation may cause damage to the vehicle’s lights. Please take care to comply with
your state’s laws when installing trailer lights.
■When towing a trailer
Disable the following systems, as the systems may not operate properly.
●LTA (Lane Tracing Assist) ( P. 2 4 2 )
●Dynamic radar cruise control with full-
speed range ( P.252)
●PKSB (Parking Support Brake)
( P.291)
●BSM (Blind Spot Monitor) (P.270)
●Toyota parking assist-sensor ( P.275)
●RCTA (Rear Cross Traffic Alert) func- tion ( P.285)
■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).

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.183)
■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 with full-speed range:
Do not use dynamic radar cruise control when you are towing.
NOTICE
■Do not directly splice trailer lights
Directly splicing trailer lights may damage your vehicle’s electrical sys-tem and cause a malfunction.
