Maintenance and care
WARNING
■Replacing light bulbs
● Turn off the lights. Do not attempt to replace the bulb immediately after
turning off the lights.
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
● Do not attempt to repair or disassemble light bulbs, connectors, electric
circuits or component parts.
Doing so may result in death or serious injury due to electric shock.
■ To prevent damage or fire
● Make sure bulbs are fully seated and locked.
● Check the wattage of the bulb before installing to prevent heat damage.

When trouble arises
If a tow truck is not available in an emergency, your vehicle may be
temporarily towed using cables or chains secured to the emergency
towing hooks. This should only be attempted on hard surfaced roads
for at most 80 km (50 miles) at under 30 km/h (18 mph).
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
Securely attach cables or
chains to the towing hooks.
Take care not to damage the vehi-
cle body.
Enter the vehicle being towed and start the engine.
If the engine does not start, turn the engine switch to the “ON” position
(vehicles without smart entry & start system) or IGNITION ON mode (vehi-
cles with smart entry & start system).
Vehicles with Stop & Start system:
Before towing the vehicle, turn the engine switch to the “LOCK” position
(vehicles without smart entry & start system) or off (vehicles with smart
entry & start system) once, and then start the engine.
4WD models: Turn the front-wheel drive control switch to H2.
( P. 363)

NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type
truck
● Do not tow the vehicle from the rear when the engine switch is in the
“LOCK” position or the key is removed (vehicles without smart entry & start
system) or the engine switch is turned to off (vehicles with smart entry &
start system). The steering lock mechanism is not 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 rear.
■ To prevent damage to the vehicle during emergency towing
Do not secure cables or chains to the suspension components.
■ When towing a vehicle equipped with the Stop & Start system (if
equipped)
When it is necessary to tow the vehicle with all four wheels contacting the
ground, perform the following procedure before towing the vehicle to protect
the system.
Turn the engine switch to the “LOCK” position (vehicles without smart entry
& start system) or off (vehicles with smart entry & start system) once, and
then start the engine. If the engine does not start, turn the engine switch to
the “ON” position (vehicles without smart entry & start system) or IGNITION
ON mode (vehicles with smart entry & start system).

Improper use of the tire jack may cause the vehicle to suddenly fall off the
jack, leading to death or serious injury.
● Do not use the tire jack for any purpose other than replacing tires or install-
ing and removing tire chains.
● Only use the tire jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, and do not use other tire jacks for replac-
ing tires on this vehicle.
● Make sure the tire jack can be moved properly.

While raising, secure the tire, tak-
ing care that the tire goes straight
up without catching on any sur-
rounding part, to prevent it from fly-
ing forward during a collision or
sudden braking.
After the tire goes half way up,
check that the suspended chain is
able to enter the tire hole, for
proper storage.
Tightening torque:
37.0 N•m (3.8 kgf•m, 27.3 ft•lbf)
Confirm that the tire is not loose
after tightening:
Push and pull the tire
Try rotating
Visually check to ensure the tire is
not hung on surrounding parts.
If looseness or misassembly exists, repeat step and step .
Repeat step , any time the tire is lowered or disturbed.
Push in the projection on the
jack handle and disassemble

When trouble arises
■Starting the engine when the battery is discharged (vehicles with auto-
matic transmission)
The engine cannot be started by push-starting.
■ To prevent battery discharge
● Turn off the headlights and the audio system while the engine is off.
(Vehicles with Stop & Start system: Except when the engine is stopped due
to the Stop & Start system)
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ When the battery is removed or discharged
● Information stored in the ECU is cleared. When the battery is depleted, have
the vehicle inspected at any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
● The power windows may not close normally. In this case, initialize the power
windows. (if equipped) ( P. 234)
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ When recharging or replacing the battery (vehicles with smart entry &
start system)
● In some cases, it may not be possible to unlock the doors using the smart
entry & start system when the battery is discharged. Use the wireless
remote control or the mechanical key to lock or unlock the doors.
● The engine may not start on the first attempt after the battery has recharged
but will start normally after the second attempt. This is not a malfunction.
● The engine switch mode is memorized by the vehicle. When the battery is
reconnected, the system will return to the mode it was in before the battery
was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
● Vehicles with Stop & Start system: For a while after the battery terminals
have been disconnected or reconnected, for a while after the battery has
been replaced, the Stop & Start system may not automatically stop the
engine for approximately 5 to 60 minutes.

HILUX_OM_OM0K375E_(EE)
■ When exchanging the battery
● Use a battery that conforms to European regulations.
● Use a battery with the same case size as the previous battery and an equiv-
alent 20 hour rate capacity (20HR) or greater.
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi-
cle is not used is a short time, the battery may discharge and the engine
may not be able to start.
● Vehicles with Stop & Start system: Use a genuine battery specifically
designed for use with the Stop & Start system or a battery with equivalent
specifications to a genuine battery. If an unsupported battery is used, Stop &
Start system functions may be restricted to protect the battery.
Also, battery performance may decrease and the engine may not be able to
restart. Contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer for details.
● For details, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
