Driving
●Avoid jerky starts or sudden acceleration.
●Avoid jerky steering and sharp turns, and slow down before making a turn.
●Note that when making a turn, the trailer wheels will be closer than the vehicle
wheels to the inside of the turn. Compensate by making a wider than normal
turning radius.
●Slow down before making a turn, in crosswinds, on wet or slippery surfaces,
etc.
Increasing vehicle speed can destabilize the trailer.
●Take care when passing other vehicles . Passing requires considerable dis-
tance. After passing a vehicle, do not fo rget the length of your trailer, and be
sure you have plenty of room before changing lanes.
●To maintain engine braking efficien cy and charging system performance
when using engine braking, do not put the transmission in D.
If in the S mode, the transmission shift range position must be in 5 or lower.
●Instability happens more frequently when descending steep or long downhill
grades. Before descending, slow down and downshift. Do not make sudden
downshifts while descending st eep or long downhill grades.
●Avoid holding the brake pedal down too long or applying the brakes too fre-
quently. This could cause the brakes to overheat and result in reduced braking
efficiency.
●Due to the added load of the trailer, yo ur vehicle’s engine may overheat on hot
days (at temperatures over 85°F [30°C]) when driving up a long or steep
grade. If the engine coolant temperat ure gauge indicates overheating, imme-
diately turn off the air conditioning (if in use), pull your vehicle off the road and
stop in a safe spot. ( P. 562)

■Temporary cancelation of the LDA system
If any of the following occurs, the LDA system will be temporarily canceled. The functions
will resume after the necessary oper ating conditions have returned.
●The turn signal lever is operated.
●The brake pedal is depressed.
●The vehicle speed deviates from the operating range of the LDA system.
●The lane lines cannot be recognized while driving.
●The wiper operates continuously.
●When the lane departure warning function is activated.
Once the lane departure warning function is activated, it will be temporarily canceled
and resume a few seconds later.
■The lane departure warning
Depending on the audio system sound level or air conditioning fan noise while the audio
system or air conditioning system is in use, it may be difficult to hear the warning sound.
■After the vehicle has been parked in the sun
The LDA system may not be available and a warning message ( P. 529) will be dis-
played for a while after driving has started. When the temperature in the cabin decreases
and the temperature around the camera sensor ( P. 243) becomes suitable for its
operation, the functions will begin to operate.

●The shape of the obstacle may prevent a sensor from detecting it. Pay particular atten-
tion to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materi
als that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehi-
cle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detect ion may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility th at the obstacle will come within the sensor’s detection
areas before the display is shown and the buzzer sounds.
• Thin posts or objects lower than the sens or may not be detected when approached,
even if they have been detected once.
• It might be difficult to hear beeps due to th e volume of audio system or air flow noise
of the air conditioning system.
■If a message is displayed on the multi-information display
 P. 528
■Certification for the intuitive parking assist (Canada only)
This ISM device complies with Canadian ICES-001.
■Customization
Settings (e.g. buzzer sounds volume) can be changed.
