Driving
4RUNNER (U)• When the vehicle is hit by water, snow, dust, etc. from a vehicle ahead
• When driving through steam or smoke
• When  there  are  patterns  or  paint  on  the  road  or  a  wall  that  may  be  mis-
taken for a vehicle or pedestrian
• When  driving  near  an  object  that  reflects  radio  waves,  such  as   a  large
truck or guardrail
• When driving near a TV tower, broadcasting station, electric power plant, or  other  location  where  strong  radio  waves  or  electrical  noise  may  be
present
■ Situations in which the syst em 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 unload ed 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 ahe ad
• If a vehicle cuts in front of your vehicle or emerges from bes ide a vehicle
• When  driving  through  or  under
objects  that  may  contact  the  vehicle,
such as thick grass, tree branches, or
a banner
• 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  water  or  snow  thrown  up  by  the  surrounding  vehicles  hinders  the
detecting of the sensor
■ Conditions  under  which  the  vehic le-to-vehicle  distance  control mode
may not function correctly
In the case of the following conditions, operate the brake peda l (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.
● When the vehicle ahead of you decelerates suddenly
● When driving on a road surrounded by a structure, such as in a  tunnel or on
a bridge
● While  the  vehicle  speed  is  decreasing  to  the  set  speed  after  th e  vehicle
accelerates by depressing the accelerator pedal
●
When  your  vehicle  is  pointing  upwards
(caused by a heavy load in the luggage
compartment, etc.)
● Preceding  vehicle  has  an  extremely
high ground clearance
●When  the  road  curves  or  when  the
lanes are narrow
● When  steering  wheel  operation  or  your
position in the lane is unstable

4RUNNER (U)
●Specific design charac teristics give it a higher center of grav ity than
ordinary  passenger  cars.  This  vehi cle  design  feature  causes  this
type  of  vehicle  to  be  more  likel y  to  rollover.  And,  utility  vehicles
have a significantly higher rollover rate than other types of v ehicles.
● An advantage of the higher ground  clearance is a better view of the
road allowing you to anticipate problems.
● It is not designed for cornering at the same speeds as ordinary  pas-
senger  cars  any  more  than  low-s lung  sports  cars  designed  to  per-
form satisfactorily under off-road conditions. Therefore, sharp  turns
at excessive speeds may cause rollover.
Off-road precautions
This  vehicle  belongs  to  the  utility  vehicle  class,  which  has
higher  ground  clearance  and  narrower  tread  in  relation  to  the
height of its center of gravity t o make it capable of performin g in
a wide variety of of f-road applications.

4RUNNER (U)
WARNING
■While towing
● When towing using cables or chains, avoid sudden starts, etc. w hich place
excessive stress on the towing eyelets, cables or chains. The towing eye-
lets,  cables  or  chains  may  become  damaged, broken  debris  may  hit  peo-
ple, and cause serious damage.
● Vehicles without a smart key system: Do not turn the engine switch to the
“LOCK” position. 
There is a possibility that the steering wheel is locked and ca nnot be oper-
ated.
● Vehicles with a smart key system: Do not turn the engine switch off. 
There is a possibility that the steering wheel is locked and ca nnot be oper-
ated.
NOTICE
■ To  prevent  damage  to  the  vehicle  when  towing  using  a  wheel-lift  type
truck
● 2WD models without a smart key system: Do not tow the vehicle f rom the
rear  when  the  engine  switch  is  in  the  “LOCK”  position  or  the  ke y  is
removed.  The  steering  lock  mechanism  is  not  strong  enough  to  ho ld  the
front wheels straight.
● 2WD models with a smart key system: Do not tow the vehicle from  the rear
when  the  engine  switch  is  off. The  steering  lock  mechanism  is  n ot  strong
enough to hold the front wheels straight.
● When raising the vehicle, ensure adequate ground clearance for  towing at
the  opposite  end  of  the  raised  vehicle.  Without  adequate  clearance,  the
vehicle could be damaged 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 re ar.
■ To prevent damage to the vehic le during emergency towing
Do not secure cables or chains to the suspension components.
