is dangerous. ( P.524)
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.524)
■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.
1 516 mm (20.31 in.)
2 516 mm (20.31 in.)
WA R N I N G
■When the gross vehicle mass or
maximum permissible axle
capacity is exceeded
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 recom-
mended tire inflation pressure
value. ( P.533)
●Do not exceed the established
speed limit for towing a trailer in built-up areas or 100 km/h (62
mph), whichever is lower.

4-1. Before driving
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)

1584-1. Before driving
NOTICE
■Do not directly splice trailer
lights
Directly splicing trailer lights may damage your vehicle’s electrical sys-
tem and cause a malfunction.
Trailer towing (except
for M15A-FKS engine)
Toyota does not recommend
towing a trailer with your vehi-
cle. Toyota also does not rec-
ommend the installation of a
tow hitch or the use of a tow
hitch carrier for a wheelchair,
scooter, bicycle, etc. Your vehi-
cle is not designed for trailer
towing or for the use of tow
hitch mounted carriers.

■Caution while driving
If engine failure occurs while the vehi-
cle is moving, do not lock or open the doors until the vehicle reaches a safe
and complete stop. Activation of the
steering lock in this circumstance may lead to an accident, resulting in death
or serious injury.
NOTICE
■When starting the engine
●Do not race a cold engine.
●If the engine becomes difficult to
start or stalls frequently, have your vehicle checked by any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer immediately.
■Symptoms indicating a malfunc-tion with the engine switch
If the engine switch seems to be oper-
ating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact
any authorized Toyota retailer or
Toyota authorized repairer, or any reli- able repairer immediately.

●If you want to stop the engine in an
emergency while driving the vehi- cle, press and hold the engine
switch for more than 2 seconds, or
press it briefly 3 times or more in succession. ( P.462)
However, do not touch the engine
switch while driving except in an emergency. Turning the engine off
while driving will not cause loss of
steering or braking control, but the power assist to these systems will
be lost. This will make it more diffi-
cult to steer and brake, so you should pull over and stop the vehi-
cle as soon as it is safe to do so.

*: If equipped
*1: To improve fuel efficiency and
reduce noise, shift the shift lever to D
for normal driving.

*3: For M15A-FKS engine
■If “Transmission Oil Temp. High
Stop in a Safe Place and See Owner’s Manual” is displayed on

M15A-FKS engine)
Reduce speed by easing off the acceler-
ator pedal. Stop the vehicle in a safe
place, shift the shift lever to P and let the
engine idle until the warning message
goes out.
When the warning message goes out,
the vehicle can be driven again.
If the warning message does not go out after waiting a while, have your vehicle
inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■When driving with the cruise con-
trol, dynamic radar cruise control
or dynamic radar cruise control with full-speed range activated (if
equipped)
Even when switching the driving mode to sport mode with the intent of enabling
engine braking, engine braking will not
occur because cruise control, dynamic radar cruise control or dynamic radar
cruise control with full-speed range will
not be canceled. ( P.314)
