2016 TOYOTA TACOMA overheating

922. Instrument cluster
WARNING
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This lag could cause the driver to down-
shift again, causing rapid and excessive engine braking and possibly an
accident resulting in personal death or injury.
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
●The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 561)

1604-1. Before driving
WARNING
●Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one. Reflected sunlight may cause
the glass to act as a lens, causing a fire.
●Always apply the parking brake, shift the shift lever to P (automatic trans-
mission only), stop the engine and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
●Do not touch the exhaust pipes while the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
●If the power brake assist function does not operate, do not follow other
vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
Have your brakes fixed immediately.
●Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
●The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase. Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively when any of the tires is up in the air, or
the vehicle is stuck in sand, mud, etc. This may damage the driveline com-
ponents or propel the vehicle forward or backward, causing an accident.

1804-1. Before driving
●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 consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you have plenty of room before changing
lanes.
●Vehicles with an automatic transmission: To maintain engine brak-
ing efficiency and charging system performance when using engine
braking, do not use the transmission in D. If in the S mode, the
transmission shift range position must be in 5 or lower.
●Vehicles with a manual transmission: To maintain engine braking
efficiency and charging system performance when using engine
braking, do not use the fifth gear (5-speed manual transmission) or
the sixth gear (6-speed manual transmission).
●Instability happens more frequently when descending steep or long
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 brakes
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 driving
up a long or steep grade. If the engine coolant temperature gauge
indicates overheating, immediately turn off the air conditioning (if in
use), pull your vehicle off the road and stop in a safe spot.
(P. 561)

1924-2. Driving procedures
■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNI-
TION ON mode (the engine is not running) for more than an hour with the
shift lever in P, the engine switch will automatically turn off. However, this
function cannot entirely prevent battery discharge. Do not leave the vehicle
with the engine switch in ACCESSORY or IGNITION ON mode for long peri-
ods of time when the engine is not running.
■Electronic key battery depletion

■Note for the entry function
P. 125
■If the engine does not start
●The engine immobilizer system may not have been deactivated. (P. 69)
Contact your Toyota dealer.
●Check that the shift lever is securely set in P. The engine may not start if the
shift lever is displaced out of P. “Shift to P Position” will be displayed on the
multi-information display.
■Steering lock
After turning the engine switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
engine switch again automatically cancels the steering lock.
■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, operation of the motor
may be suspended if the engine is turned on and off repeatedly in a short
period of time. In this case, refrain from running the engine. After about
10 seconds, the steering lock motor will resume functioning. A message will be displayed on the multi-
information display.
Check that the shift lever is in P. Press the
engine switch while turning the steering
wheel left and right.

■Automatic system cancelation
In the following situations, the buzzer will sound intermittently and Crawl Con-
trol will be canceled automatically. In this event, the Crawl Control indicator
will flash and then goes off, and a message stating that Crawl Control has
been turned off will be displayed on the multi-information display for several
seconds.
●When the shift lever is shifted to P or N
●When the front-wheel drive control switch is turned to “4H”
●When the driver’s door is opened
■Function limitations
When the vehicle speed exceeds approximately 15 mph (25 km), engine con-
trol and brake control will stop temporarily. In this event, the Crawl Control
indicator will flash.
■When the Crawl Control system is operated continuously
●If Crawl Control is used continuously for a long time, the buzzer will sound, a
malfunction notification will be displayed on the multi-information display,
the Crawl Control indicator goes off, and Crawl Control will be temporarily
inoperable as a result of the brake system overheating. In this event, stop
the vehicle immediately in a safe place, and allow the brake system to cool
down sufficiently until the “TRAC OFF” indicator will goes off. (In the mean-
time, normal driving is possible.)
●If Crawl Control is used continuously for a long time, the buzzer will sound,
the system will be temporarily canceled, and a malfunction notification will
be displayed on the multi-information display as a result of the automatic
transmission system overheating. Stop the vehicle in a safe place until the
display goes off.
■Sounds and vibrations caused by the Crawl Control system
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate
that a malfunction has occurred in Crawl Control system.
●Either of the following conditions may occur when the Crawl Control system
is operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
■When there is a malfunction in the system
Warning lights and/or warning messages will turn on. (P. 519)

■Burns
●Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)
●Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
●Do not use seat heater more than necessary. Doing so may cause minor
burns or overheating.
NOTICE
■To prevent damage to the seat heaters
Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.
■To prevent battery discharge
Turn the seat heaters off when the engine is not running.
