1904-1. Before driving
SEQUOIA_OM_USA_OM0C013U_19MY
●Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before maki ng
turns.
● Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by mak ing
a wider than normal turning radius.
● Slow down before making a turn, in cross winds, on wet or slipp ery
surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the lengt h of
your trailer, and be sure you have plenty of room before changi ng
lanes.
● To maintain engine braking efficiency and charging system perfo r-
mance when using engine braking, do not put the transmission in
D.
● Instability happens more frequently when descending steep or lo ng
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the bra kes
too frequently. This could cause the brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may over-
heat on hot days (at temperatures over 85 °F [30 °C]) when driv ing
up a long or steep grade. If the engine coolant temperature gau ge
indicates overheating, immediately turn off the air conditionin g (if in
use), pull your vehicle off the road and stop in a safe spot.

WARNING
■Trailer towing precautions
● To tow a trailer safely, use extreme care and drive the vehicle in accor-
dance with the trailer’s characteristics and operating conditions. Failure to
do so could cause an accident resulting in death or serious injury. Vehicle
stability and braking performance are affected by trailer stability, brake set-
ting and performance, and the hitch. Your vehicle will handle differently
when towing a trailer.
● Vehicles with electronically modulated air suspension: Set the vehicle
height to the “N” mode and turn off the rear height control air suspension
when you connect a trailer, otherwise the vehicle height may ch ange due
to the automatic leveling function, and you may catch part of your body in
the vehicle, resulting in an accident.
■ To avoid accident or injury
● Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR.
● If the gross trailer weight is over 2000 lb. (907 kg), a sway control device
with sufficient capacity is required.
● If the gross trailer weight is over 5000 lb. (2268 kg), a weight distributing
hitch with sufficient capacity is required.
● Adjust the tongue weight within the appropriate range. Place heavier loads
as close to the trailer axle as possible.
● Do not exceed 65 mph (104 km/h), the posted towing speed limit or the
speed limit for your trailer as set forth in your trailer owner’s manual,
whichever is lowest. Slow down sufficiently before making a tur n, in cross
winds, on wet or slippery surface, etc. to help avoid an accident. If you
experience a vehicle-trailer instability from reducing a certai n speed, slow
down and make sure you keep your vehicle speed under the speed of
which you experience the instability.
● Do not make jerky, abrupt or sharp turns.

WARNING
■Before using LDA system
Do not rely solely upon the LDA system. The LDA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by always paying careful atte ntion to the sur-
rounding 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, re sulting in
death or serious injury.
● A compact spare tire, tire chains, etc., are equipped.
● Objects or patterns that could be mistaken for white (yellow) l ines 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.

Limitations of the sensors
●The detection areas of the sensors are limited to the areas aro und the vehi-
cle’s front corners and the rear bumpers.
● Certain vehicle conditions and surrounding environments, such a s the fol-
lowing, may affect the ability of the sensors to correctly dete ct objects. Pay
particular attention in the following situations. Failure to do so may result in
the vehicle being driven unsafely, possibly leading to an accident.
• When there is dirt, snow or ice on a sensor (Cleaning the sens or will
resolve this problem.)
• When the sensor is frozen (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen ma y show an
abnormal display, or objects may not be detected
• When a sensor is covered in any way
• When the vehicle is leaning considerably to one side
• When driving on an extremely bumpy road, incline, gravel, or g rass
• When the vicinity of the vehicle is noisy due to vehicle horns , motorcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves
• When there is another vehicle equipped with parking assist sen sor in the
vicinity
• When the sensor is coated with a sheet of spray or heavy rain
• When the vehicle is equipped with a fender pole or wireless an tenna
• When a towing eyelet is installed
• When a bumper or sensor receives a strong impact
• A backlit license plate, license plate holder, etc., are insta lled.
• When the vehicle is approaching a tall or curved curb
• When driving in harsh sunlight or intense cold weather
• When an object is directly under a bumper
• When objects become too close to the sensors
• When a non-genuine Toyota suspension (lowered suspension, etc. ) is
installed
In addition to the situations above, there are instances in which, because of
their shape, signs and other objects may be judged by the senso r to be
closer than they are.

2744-5. Using the driving support systems
SEQUOIA_OM_USA_OM0C013U_19MY●
The shape of an object may prevent the sensor from detecting it. Pay partic-
ular attention to the following:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low objects
• Tall objects with upper sections projecting outwards in the direction of
your vehicle
• People, animals and other moving objects
• People wearing certain types of clothing
● The following situations may occur when using the intuitive parking assist.
• Depending on the shape of the object and other factors, the de tection dis-
tance may be shortened, or detection may not be possible.
• Objects may not be detected if they are too close to a sensor.
• There will be a short delay between the detection of an object and display
of the detection. Even at slow speeds, there is a possibility t hat the object
will come within a sensor’s detection area before the display i s shown
and a warning beep sounds.
• Thin posts or objects lower than a sensor may not be detected when
approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of the a udio system
or air flow noise of the air conditioning system.

Perform the following according to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is fr ozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ic e or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to roa d con-
ditions.
● Park the vehicle and move the shift lever to P without setting the
parking brake. The parking brake may freeze up, preventing it from
being released. If the vehicle is parked without setting the pa rking
brake, make sure t o block the wheels.
Failure to do so may be dangerou s because it may cause the vehi-
cle to move unexpectedly, pos sibly leading to an accident.
● If the vehicle is parked without setting the parking brake, confirm
that the shift lever c annot be moved out of P
*.
*: The shift lever will be locked if it is attempted to be shifte d from P to any
other position without depressing the brake pedal. If the shift lever can be
shifted from P, there may be a problem with the shift lock syst em. Have the
vehicle inspected by your Toyota dealer immediately.
