Toyota Highlander Owners Manual: If the vehicle battery is
discharged
The following procedures may be used to start the engine if the
vehicle’s battery is discharged.
You can also call your toyota dealer or a qualified repair shop.
If you have a set of jumper (or booster) cables and a second vehicle
with a 12-volt battery, you can jump start your vehicle by following the
steps below.
- Open the hood.
- Connect the jumper cables according to the following procedure:
- 2.7 L 4-cylinder (1ar-fe) engine
- Connect a positive jumper cable clamp to the positive (+) battery
terminal on your vehicle.
- Connect the clamp on the other end of the positive cable to the
positive (+) battery terminal on the second vehicle.
- Connect a negative cable clamp to the negative (-) battery terminal
on the second vehicle.
- Connect the clamp at the other end of the negative cable to a
solid, stationary, unpainted metallic point away from the battery
and any moving parts, as shown in the illustration.
- Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the battery of your vehicle.
- Vehicles with a smart key system: open and close any of the doors
of your vehicle with the engine switch off.
- Vehicles without a smart key system:
maintain the engine speed of the second vehicle and turn the
engine switch to the “on” position, then start the vehicle's engine.
Vehicles with a smart key system:
maintain the engine speed of the second vehicle and turn the
engine switch to ignition on mode, then start the vehicle's
engine.
- Once the vehicle’s engine has started, remove the jumper cables in
the exact reverse order from which they were connected.
Once the engine starts, have the vehicle inspected at your toyota
dealer as soon as possible.
Starting the engine when the battery is discharged
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.
- 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 recharging or replacing the battery
- Vehicles with a smart key system: in some cases, it may not be possible
to
unlock the doors using the smart key system when the battery is discharged.
Use the wireless remote control or the mechanical key to lock or
unlock the doors.
- Vehicles with a smart key system: 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.
- Vehicles with a smart key system: 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
discharged,
be especially careful when reconnecting the battery.
- Vehicle with power back door: the power back door must be initialized.
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
certain
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.)
Warning
Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting
the flammable
gas that may be emitted from the battery:
- make sure each jumper cable is connected to the correct terminal
and that
it is not unintentionally in contact with any other than the
intended terminal.
- Do not allow the other end of the jumper cable connected to the
ƒg+ƒh terminal
to come into contact with any other parts or metal surfaces in the
area,
such as brackets or unpainted metal.
- Do not allow the + and - clamps of the jumper cables to come
into contact
with each other.
- Do not smoke, use matches, cigarette lighters or allow open
flame near
the battery.
