■Situations in which the system may not operate properly
●In some situations such as the following, a vehicle may not be detected by the radar
sensor and camera sensor, preventing the system from operating properly:
• If an oncoming vehicle is approaching your vehicle
• If a vehicle ahead is a motorcycle or bicycle
• When approaching the side or front of a vehicle
• If a preceding vehicle has a small rear end, such as an unloaded truck
• If a vehicle ahead is carrying a load which protrudes past its rear bumper
• If a vehicle ahead is irregularly shaped, such as a tractor or side car
• If the sun or other light is shining directly on a vehicle ahead
• If a vehicle cuts in front of your vehicle or emerges from beside a vehicle
• If a vehicle ahead makes an abrupt maneuver (such as sudden swerving, accelera-
tion or deceleration)
• When suddenly cutting behind a preceding vehicle
• When driving in inclement weather such as heavy rain, fog, snow or a sandstorm
• When the vehicle is hit by water, snow, dust, etc. from a vehicle ahead
• When driving through steam or smoke
• When driving in a place where the surrou nding brightness changes suddenly, such
as at the entrance or exit of a tunnel
• When a very bright light, such as the sun or the headlights of oncoming traffic, shines directly into the camera sensor
• When the surrounding area is dim, such as at dawn or dusk, or while at night or in a
tunnel
• If a preceding vehicle has a low rear end,
such as a low bed trailer
• If a vehicle ahead has extremely high ground clearance
• When a vehicle ahead is not directly in front of your vehicle

■Warning messages and buzzers for dynamic radar cruise control with full-speed range
Warning messages and buzzers are used to indicate a system malfunction or to inform
the driver of the need for caution while driv
ing. If a warning message is shown on the
multi-information display, read the message and follow the instructions. ( →P. 4 5 9 )
■When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the brake pedal
when deceleration of the system is insufficient or operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the approach
warning ( →P. 273) may not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same lane
●Vehicles with small rear ends (trailers with no load on board, etc.)
●Motorcycles traveling in the same lane
●When water or snow thrown up by the surrounding vehicles hinders the detecting of
the sensor
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage com-
partment, etc.)
●Preceding vehicle has an extremely high
ground clearance

When trouble arises
NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type truck
●Do not tow the vehicle from the rear when the engine switch is off. The steering lock
mechanism is not strong enough to hold the front wheels straight.
●When raising the vehicle, ensure adequate ground clearance for towing at the oppo-
site end of the raised vehicle. Without adequate clearance, the vehicle could be dam-
aged while being towed.
■To prevent damage to the vehicle when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
■To prevent damage to the vehicle during emergency towing
Do not secure cables or chains to the suspension components.
■Recreational towing (behind motor home, etc.)
Never dinghy tow your vehicle to prevent caus-
ing serious damage to the transfer (AWD mod-
els) and transmission.
