5-1. Before driving
Driving
is especially true when driving on
wet or slippery road surfaces.
■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 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
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut-
ing lane changes.
■If the EV system overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the EV system overheating. If the
EV system coolant temperature
gauge indicates that the EV system
is overheating, turn the air condi-
tioning off immediately, leave the
road and stop the vehicle in a safe
place. ( P.549)
■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 position to P.
WARNING
F o l l o w a l l t h e i n s t r u c t i o n s d e s c r i b e d i n 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.554)
■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.

■Sounds and vibrations caused by the ABS, brake assist, VSC, Trailer Sway Control, TRC and hill-start
assist control systems
●A sound may be heard from the motor
compartment when the brake pedal is depressed repeatedly, when the EV system is started or just after the vehi-
cle begins to move. This sound does not indicate that a malfunction has occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.• Vibrations may be felt through the
vehicle body and steering. • A motor sound may be heard also after the vehicle comes to a stop.
■ECB operating sound
ECB operating sound may be heard in the following cases, but it does not indi-cate that a malfunction has occurred.
●Operating sound heard from the motor compartment when the brake pedal is
operated.
●Operating sound heard from the motor
compartment when one or two min- utes passed after the stop of the EV system.
■Active Cornering Assist operation
sounds and vibrations
When Active Cornering Assist is oper- ated, operation sounds and vibrations
may be generated from the brake sys- tem, but this is not a malfunction.
■EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be heard. This does not indicate a malfunc-tion.
■Automatic reactivation of TRC,
Trailer Sway Control and VSC sys- tems
After turning the TRC, Trailer Sway Con-
trol and VSC systems off, the systems will be automatically re-enabled in the following situations:
●When the power switch is turned off
●If only the TRC system is turned off, the TRC will turn on when vehicle speed increases. If both the TRC and
VSC systems are turned off, auto- matic re-enabling will not occur when vehicle speed increases.
■Operating conditions of Active Cor-
nering Assist
The system operates when the following occurs.
●TRC/VSC can operate
●The driver is attempting to accelerate while turning
●The system detects that the vehicle is drifting to the outer side
●The brake pedal is released
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is
reduced to prevent the system from overheating when there is frequent steering input over an extended period
of time. The steering wheel may feel heavy as a result. Should this occur, refrain from excessive steering input or
stop the vehicle and turn the EV system off. The EPS system should return to normal within 10 minutes.
■Operating conditions of emergency
brake signal
When the following conditions are met, the emergency brake signal will operate:
●The emergency flashers are off.
●Actual vehicle speed is over 55 km/h (35 mph).
