■Tire information
● Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi)
greater than the recommended value when towing. ( P. 640)
● Increase the air pressure of the trailer tires in accordance with the total
trailer weight and according to the values recommended by the manufac-
turer of your trailer.
■ Tr a i l e r l i g h ts
Check that the turn signal lights and stoplights are operating correctly every
time you hitch up the trailer. Direct ly wiring up to your vehicle may damage
the electrical system and stop the lights from functioning correctly.
■ When towing a trailer
Disable the following systems, as the systems may not operate properly.
● LDA (Lane Departure Alert With Yaw Assist Function) (If equipped)
( P. 283)
● Dynamic radar cruise control (If equipped) (P. 300)
● Cruise control (If equipped) (P. 316)
● Toyota parking assist-sensor (If equipped) (P. 320)
■ Break-in schedule
Toyota recommends that vehicles fitted with new power train components
should not be used for towing trailers for the first 800 km (500 miles).
■ Safety checks before towing
● Check that the maximum load limit for the towing hitch/bracket and hitch ball
is not exceeded. Bear in mind that the coupling weight of the trailer will add
to the load exerted on the vehicle. Also make sure that the total load exerted
on the vehicle is within the range of the weight limits. ( P. 211)
● Ensure that the trailer load is secure.
● Supplementary outside rear view mirrors should be added to the vehicle if
the traffic behind cannot be clearly seen with standard mirrors. Adjust the
extending arms of these mirrors on both sides of the vehicle so that they
always provide maximum visibility of the road behind.
■ Maintenance
● Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight burden placed on the vehicle compared to
normal driving.
● Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).

Driving
HILUX_OM_OM0K789E_(EE)
■ When the steering lock cannot be released
■ Key reminder function
A buzzer sounds if the driver’s door is opened while the engine switch is in
the “LOCK” or “ACC” position to remind you to remove the key.
When starting the engine, the engine
switch may seem stuck in the “LOCK”
position. To free it, turn the key while turn-
ing the steering wheel slightly left and
right.
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 when driving
Do not turn the engine switch to the “LOCK” position while driving.
If in an emergency, you must turn the engine off while the vehicle is moving,
turn the engine switch only to the “ACC” position to stop the engine. An
accident may result if the engine is stopped while driving. ( P. 555)
NOTICE
■To prevent battery discharge
Do not leave the engine switch in the “ACC” or “ON” position for long peri-
ods of time without the engine running.
■ When starting the engine
● Do not crank the engine for more than 30 seconds at a time. This may
overheat the starter and wiring system.
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer immediately.

Maintenance and care
HILUX_OM_OM0K789E_(EE)
■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle’s interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-
ing the carpet as dry as possible.
■ Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
WARNING
■ Water in the vehicle
● Do not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch
fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
( P. 46)
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
■ Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect
off the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.

5247-3. Do-it-yourself maintenance
HILUX_OM_OM0K789E_(EE)
■After a fuse is replaced
● If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. ( P. 525)
● If the replaced fuse blows again, have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
WARNING
■ To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
● Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.
● Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
● Do not modify the fuses or fuse boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer as soon as possible.

6148-2. Steps to take in an emergency
HILUX_OM_OM0K789E_(EE)
If you run out of fuel and the engine stalls
(diesel engine only)
If you run out of fuel and the engine stalls:
Refuel your vehicle.
To bleed the fuel system, oper-
ate the priming pump until you
feel more resistance.
Start the engine. ( P. 219, 222)
If the engine does not start after the above steps have been performed,
wait for 10 seconds and try steps and again. If the engine still does
not start, contact any authorized Toyo ta retailer or Toyota authorized
repairer, or any reliable repairer.
After starting the engine, depress the accelerator pedal lightly until the
