4-1. Before driving

4RUNNER (U)

WARNING

Do not apply the brakes suddenly as you may skid, resulting in jackknifing
and loss of vehicle control. This is especially true on wet or slippery sur-
faces.

Do  not  exceed  the  trailer  hitch  assembly  weight,  gross  vehicle  weight,
gross axle weight and trailer tongue weight capacities.

Do not use cruise control when towing.

Slow  down  and  downshift  before  descending  steep  or  long  downhill
grades. Do not make sudden downshifts while descending steep or long
downhill grades.

Vehicle-trailer  instability  is  more  likely  on  steep  long  downhills.  Before
descending steep or long downhill grades, slow down and downshift. Do
not  make  sudden  downshifts  when  descending  steep  or  long  downhill
grades.  Avoid  holding  the  brake  pedal  down  too  long  or  applying  the
brakes too frequently. This could cause the brakes to overheat and result
in reduced braking efficiency.

Hitch

Trailer hitch assemblies have different weight capacities established by the
hitch manufacturer. Even though the vehicle may be physically capable of
towing a higher weight, the operator must determine the maximum weight
rating  of  the  particular  hitch  assembly  and  never  exceed  the  maximum
weight rating specified for the trailer-hitch. Exceeding the maximum weight
rating set by the trailer-hitch manufacturer can cause an accident resulting
in death or serious personal injuries.

When towing a trailer

Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.

If  the  gross  trailer  weight  exceeds  unbraked  TWR,  trailer  brakes  are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.

Never tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’s braking effectiveness.

Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is danger of the trailer wandering into another lane.

WARNING

When starting the engine

Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.

Caution while driving

If engine failure occurs while the vehicle 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.

Stopping the engine in an emergency

If you want to stop the engine in an emergency while driving the vehicle,
press  and  hold  the  engine  switch  for  more  than  2  seconds,  or  press  it
briefly 3 times or more in succession. (

P. 463)

However, do not touch the engine switch while driving except in an emer-
gency. 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 difficult to steer and brake, so you should pull over and stop
the vehicle as soon as it is safe to do so.

If  the  engine  switch  is  operated  while  the  vehicle  is  running,  a  warning
message  will  be  shown  on  the  multi-information  display  and  a  buzzer
sounds.

When parking

Exhaust gases  include harmful  carbon  monoxide  (CO), which is colorless
and odorless. Observe the following precautions.
Failure  to  do  so  may  cause  exhaust  gases  to  enter  the  vehicle  and  may
lead to an accident caused by light-headedness, or may lead to death or a
serious health hazard.

If  the  vehicle  is  in  a  poorly  ventilated  area  or  a  closed  area,  such  as  a
garage, stop the engine.

Do not leave the vehicle with the engine running for a long time. If such a
situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior.

Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle.

display,  the  engine  switch  is  not  off.  Exit  the  vehicle  after  turning  the
engine switch off.

Do not stop the engine when the shift lever is in a position other than P. If
the engine is stopped in another shift lever position, the engine switch will
not be turned off but instead be turned to ACCESSORY mode. If the vehi-
cle is left in ACCESSORY mode, battery discharge may occur.

When starting the engine

Do not race a cold engine.

If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by your Toyota dealer immediately.

Symptoms indicating a malfunction with the engine switch

If the engine switch seems to be operating somewhat differently than usual,
such  as  the  switch  sticking  slightly,  there  may  be  a  malfunction.  Contact
your Toyota dealer immediately.

If the shift lever cannot be shifted from P

First, check whether the brake pedal is being depressed. 
If the shift lever cannot be shifted with your foot on the brake pedal, there may
be a problem with the shift lock system. Have the vehicle inspected by your
Toyota dealer immediately.
The following steps may be used as an emergency measure to ensure that
the shift lever can be shifted.
Releasing the shift lock:

Set the parking brake.
Vehicles without a smart key system: Turn the engine switch to the “LOCK”
position. 
Vehicles with a smart key system: Turn the engine switch is off.
Depress the brake pedal.

If the “S” indicator does not come on even after shifting the shift lever to
S

This may indicate a malfunction in the automatic transmission system. Have
the vehicle inspected by your Toyota dealer immediately. 
(In this situation, the transmission will operate in the same manner as when
the shift lever is in D.)

Downshift restriction warning buzzer (S mode)

To help ensure safety and driving performance, downshifting operation may
sometimes  be  restricted.  In  some  circumstances,  downshifting  may  not  be
possible even when the shift lever is operated. (A buzzer will sound twice.) 

Pry the cover up with a flathead screw-
driver or equivalent tool.
To prevent damage to the cover, cover
the tip of the screwdriver with a rag.

Daytime running light system

Vehicles  with  a  headlight  high  beam/daytime  running  lights:  The  daytime
running lights illuminate using the same lights as the headlight high beam
and illuminate dimmer than the headlight high beam.

To make your vehicle more visible to other drivers during daytime driving,
the  daytime  running  lights  turn  on  automatically  when  all  of  the  following
conditions are met. (The daytime running lights are not designed for use at
night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the 

 (type A only), 

*

 (type B

and C) position

*

: When the surroundings are bright

The daytime running lights remain on after they illuminate, even if the park-
ing brake is set again.
Type A  and  B:  Daytime  running  lights  can  be  turned  off  by  operating  the
switch.

Compared  to  turning  on  the  headlights,  the  daytime  running  light  system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.

Headlight control sensor (if equipped)

The sensor may not function properly if an
object is placed on the sensor, or anything
that  blocks  the  sensor  is  affixed  to  the
windshield. 
Doing  so  interferes  with  the  sensor
detecting  the  level  of  ambient  light  and
may  cause  the  automatic  headlight  sys-
tem to malfunction.

Conditions to turn the high beams on/off automatically

When all of the following conditions are met, the high beams will be turned
on automatically (after approximately 1 second):
• The vehicle speed is approximately 21 mph (34 km/h) or more.
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.
• There are few streetlights on the road ahead.

If any of the following conditions is met, the high beams will turn off automat-
ically:
• The vehicle speed is below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their headlights or tail lights turned on.
• There are many streetlights on the road ahead.

Camera sensor detection information

The high beams may not be automatically turned off in the following situa-
tions:
• When a vehicle suddenly appears from around a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead cannot be detected due to repeated curves, road

dividers or roadside trees

• When vehicles ahead appear in a faraway lane on a wide road
• When the lights of vehicles ahead are not on

The high beams may be turned off if a vehicle ahead that is using fog lights
without its headlights turned on is detected.

House lights, street lights, traffic signals, and illuminated billboards or signs
and other reflective objects may cause the high beams to change to the low
beams, or the low beams to remain on.

The  following  factors  may  affect  the  amount  of  time  taken  for  the  high
beams to turn on or off:
• The  brightness  of  the  headlights,  fog  lights,  and  tail  lights  of  vehicles

ahead

• The movement and direction of vehicles ahead
• When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface,

etc.)

• The number of passengers and amount of luggage in the vehicle

The high beams may turn on or off unexpectedly.

Bicycles or similar vehicles may not be detected.

In the following situations the system may not be able to correctly detect the
surrounding brightness level. This may cause the low beams to remain on
or the high beams to flash or dazzle pedestrians or vehicles ahead. In such
a case, it is necessary to manually switch between the high and low beams.

WARNING

When refueling the vehicle

Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.

After  exiting  the  vehicle  and  before  opening  the  fuel  door,  touch  an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.

Always hold the grips on the fuel tank cap and turn it slowly to remove it. 
A  whooshing  sound  may  be  heard  when  the  fuel  tank  cap  is  loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.

Do  not  allow  anyone  that  has  not  discharged  static  electricity  from  their
body to come close to an open fuel tank.

Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.

Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.

Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.

When refueling

Observe the following precautions to prevent fuel overflowing from the fuel
tank:

Securely insert the fuel nozzle into the fuel filler neck.

Stop filling the tank after the fuel nozzle automatically clicks off.

Do not top off the fuel tank.

NOTICE

Refueling

Do not spill fuel during refueling. 
Doing  so  may  damage  the  vehicle,  such  as  causing  the  emission  control
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.

Pre-collision warning

When  the  system  determines
that  the  possibility  of  a  frontal
collision  is  high,  a  buzzer  will
sound and a warning message
will  be  displayed  on  the  multi-
information  display  to  urge  the

Pre-collision brake assist

When  the  system  determines  that  the  possibility  of  a  frontal  colli-
sion is high, the system applies greater braking force in relation to
how strongly the brake pedal is depressed.

Pre-collision braking

When  the  system  determines  that  the  possibility  of  a  frontal  colli-
sion is high, the system warns the driver. If the system determines
that the possibility of a frontal collision is extremely high, the brakes
are automatically applied to help avoid the collision or reduce the
collision speed.

PCS (Pre-Collision System)

The pre-collision system uses a radar sensor and front camera
to detect vehicles and pedestrians in front of your vehicle. When
the system determines that the possibility of a frontal collision
with a vehicle or pedestrian is high, a warning operates to urge
the  driver  to  take  evasive  action  and  the  potential  brake  pres-
sure is increased to help the driver avoid the collision. If the sys-
tem  determines  that  the  possibility  of  a  frontal  collision  with  a
vehicle or pedestrian is extremely high, the brakes are automati-
cally  applied  to  help  avoid  the  collision  or  help  reduce  the
impact of the collision.

The pre-collision system can be disabled/enabled and the warning

WARNING

Limitations of the pre-collision system

The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings. 
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys-
tem. Failure to do so may lead to an accident, resulting in death or serious
injury.

Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance. 
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-

sibility of a collision: 

P. 259

• Conditions under which the system may not operate properly: 

P. 261

Do not attempt to test the operation of the pre-collision system yourself.
Depending  on  the  objects  used  for  testing  (dummies,  cardboard  objects
imitating  detectable  objects,  etc.),  the  system  may  not  operate  properly,
possibly leading to an accident.

Pre-collision braking

When  the  pre-collision  braking  function  is  operating,  a  large  amount  of
braking force will be applied.

If the vehicle is stopped by the operation of the pre-collision braking func-
tion,  the  pre-collision  braking  function  operation  will  be  canceled  after
approximately 2 seconds. Depress the brake pedal as necessary.

The pre-collision braking function may not operate if certain operations are
performed  by  the  driver.  If  the  accelerator  pedal  is  being  depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.

In  some  situations,  while  the  pre-collision  braking  function  is  operating,
operation  of  the  function  may  be  canceled  if  the  accelerator  pedal  is
depressed strongly or the steering wheel is turned and the system deter-
mines that the driver is taking evasive action.

If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.

Operational conditions

The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:

Pre-collision warning:
• Vehicle  speed  is  between  approximately  7  and  110  mph  (10  and  180

km/h).  (For  detecting  a  pedestrian,  vehicle  speed  is  between  approxi-
mately 7 and 50 mph [10 and 80 km/h].)

• The  relative  speed  between  your  vehicle  and  the  vehicle  or  pedestrian

ahead is approximately 7 mph (10 km/h) or more.

Pre-collision brake assist: 
• Vehicle  speed  is  between  approximately  20  and  110  mph  (30  and  180

km/h).  (For  detecting  a  pedestrian,  vehicle  speed  is  between  approxi-
mately 20 and 50 mph [30 and 80 km/h].)

• The  relative  speed  between  your  vehicle  and  the  vehicle  or  pedestrian

ahead is approximately 20 mph (30 km/h) or more.

Pre-collision braking:
• Vehicle  speed  is  between  approximately  7  and  110  mph  (10  and  180

km/h).  (For  detecting  a  pedestrian,  vehicle  speed  is  between  approxi-
mately 7 and 50 mph [10 and 80 km/h].)

• The  relative  speed  between  your  vehicle  and  the  vehicle  or  pedestrian

ahead is approximately 7 mph (10 km/h) or more.

The system may not operate in the following situations:

If a battery terminal has been disconnected and reconnected and then the
vehicle has not been driven for a certain amount of time

If the shift lever is in R

If  VSC  is  disabled  (only  the  pre-collision  warning  function  will  be  opera-
tional)

If the low speed four-wheel drive indicator is illuminated (only the pre-colli-
sion warning function will be operational)

Pedestrian detection function

The pre-collision system detects pedestri-
ans based on the size, profile, and motion
of  a  detected  object.  However,  a  pedes-
trian  may  not  be  detected  depending  on
the  surrounding  brightness  and  the
motion,  posture,  and  angle  of  the
detected  object,  preventing  the  system
from operating properly. (

paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing  conditions and operating the steering wheel to  correct the  path  of  the
vehicle. Also, the driver must take adequate breaks when fatigued, such as
from driving for a long period of time. 
Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.

To avoid operating LDA system by mistake

When not using the LDA system, use the LDA switch to turn the system off.

Situations unsuitable for LDA system

Do not use the LDA system in the following situations.
The system may not operate properly and lead to an accident, resulting in
death or serious injury.

A spare tire, tire chains, etc. are equipped.

Objects  or  patterns  that  could  be  mistaken  for  white  (yellow)  lines  are
present on the side of the road (guardrails, curbs, reflective poles, etc.).

Vehicle is driven on a snow-covered road.

White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.

Asphalt  repair  marks,  white  (yellow)  line  marks,  etc.  are  present  due  to
road repair.

Vehicle is driven in a temporary lane or restricted lane due to construction
work.

Vehicle is driven in a construction zone.

Preventing  LDA  system  malfunctions  and  operations  performed  by
mistake

Do not modify the headlights or place stickers, etc. on the surface of the
lights.

Do  not  modify  the  suspension  etc.  If  the  suspension  etc.  needs  to  be
replaced, contact your Toyota dealer.

Do not install or place anything on the hood or grille. Also, do not install a
grille guard (bull bars, kangaroo bar, etc.).

If your windshield needs repairs, contact your Toyota dealer.

Operation conditions of each function

Lane departure alert function
This function operates when all of the following conditions are met.
• LDA is turned on.
• Vehicle speed is approximately 32 mph (50 km/h) or more.
• System recognizes white (yellow) lines.
• Width of traffic lane is approximately 9.8 ft. (3 m) or more.
• Turn signal lever is not operated.
• Vehicle is driven on a straight road or around a gentle curve with a radius

of more than approximately 492 ft. (150 m).

• No system malfunctions are detected. (

P. 271)

Vehicle sway warning function
This function operates when all of the following conditions are met.

• Setting for “Sway Warning” in 

 of the multi-information display is set to

“On”. (

P. 96)

• Vehicle speed is approximately 32 mph (50 km/h) or more.
• Width of traffic lane is approximately 9.8 ft. (3 m) or more.
• No system malfunctions are detected. (

Temporary cancellation of functions

When the operation conditions are no longer met, a function may be tempo-
rarily canceled. However, when the operation conditions are met again, oper-
ation of the function is automatically restored. (

P. 269)

Lane departure alert function

The warning buzzer may be difficult to hear due to external noise, audio play-
back, etc.

Vehicle sway warning function

Depending on the vehicle and road conditions, the warning may not operate.

White (yellow) lines are only on one side of road

The  LDA  system  will  not  operate  for  the  side  on  which  white  (yellow)  lines
could not be recognized.

When  the  system  determines  that  the
vehicle is swaying while the vehicle sway
warning  function  is  operating,  a  buzzer
sounds  and  a  warning  message  urging
the driver to rest and  the  symbol shown
in the illustration are simultaneously dis-
played on the multi-information display.
