For more information on the Bonnet and the Engine, refer to the corresponding sections.
Starting using another
battery
If the vehicle's battery is flat, the engine can be started using a backup battery (either external or from another vehicle) and jump leads or using a battery booster.
WARNI NG
Never start the engine by connecting a battery charger.Never use a 24 V or higher battery booster.Check beforehand that the backup battery has a nominal voltage of 12 V and a capacity at least equal to that of the discharged battery.The two vehicles must not be in contact with each other.Switch off all electricity-consuming equipment on both vehicles (audio system, wipers, lighting, etc.).Make sure that the jump leads are well away from the engine’s moving parts (fan, belt, etc.).Do not disconnect the (+) terminal while the engine is running.


► Lift the plastic cover on the (+) terminal, if the vehicle has one.► Connect the red cable to the (+) terminal of flat battery A (at the metal elbow), then to the (+) terminal of the backup battery B or of the booster.► Connect one end of the green or black cable to the (-) terminal of the backup battery B or of the booster (or to an earth point on the assisting vehicle).► Connect the other end of the green or black
cable to the earth point C.► Start the engine on the assisting vehicle and leave it running for a few minutes.► Operate the starter on the broken down vehicle and let the engine run.If the engine does not start immediately, switch off the ignition and wait a few moments before trying again.► Wait for it to return to idle.► Disconnect the jump leads in reverse order.

WARNI NG
Never try to charge a frozen battery - risk of explosion!If the battery has frozen, have it checked by any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer who will verify that the internal components have not been damaged and that the case
has not cracked, which would mean a risk of toxic and corrosive acid leaking.
Disconnecting the battery
In order to maintain an adequate state of charge for starting the engine, we recommend disconnecting the battery if the vehicle is to be unused for an extended period.Before disconnecting the battery:► Close all openings (doors, tailgate, windows).► Switch off all electricity-consuming devices (audio system, wipers, lamps, etc.).
► Switch off the ignition and wait for 4 minutes.After accessing the battery, it is only necessary to disconnect the (+) terminal.

Frequently asked
questions
The following information groups together the answers to the most frequently asked questions concerning your audio system.With the engine off, the audio system switches off after a few minutes of use.When the engine is switched off, the audio system operating time depends on the state of charge of the battery.The switch-off is normal: the audio system switches to economy mode and switches off to avoid discharging the vehicle's battery.► Start the vehicle’s engine to increase the charge of the battery.The message "the audio system is overheated" is displayed onscreen.To protect the installation if the ambient temperature is too high, the audio system switches to an automatic thermal protection mode, in which the volume may be decreased or the CD player stopped.► Switch the audio system off for a few minutes to allow the system to cool.
Radio
There is a difference in sound quality between the different audio sources (radio, CD, etc.).For optimal listening quality, the audio settings (Volume, Bass, Treble, Ambience and Loudness) can be adjusted to different audio sources, resulting in audible differences when switching between sources (radio, CD, etc.).
► Check that the audio settings (Volume, Bass, Treble, Ambience and Loudness) are appropriate to the sources being listened to. We recommend setting the audio functions (Bass, Treble, Fr-Re balance and Le-Ri balance) to the middle position, setting the musical ambience to "None", setting loudness correction to "Active" in CD mode and "Inactive" in Radio mode.The preset stations do not function (no sound, 87.5 MHz is displayed, etc.).The wrong waveband is selected.► Press the BAND button to return to the waveband (FM, FM2, DAB, AM) on which the stations are preset.Traffic announcement (TA) is shown but I receive no traffic information.The radio station is not part of the regional traffic information network.► Tune to a radio station that broadcasts traffic information.The reception quality of the tuned radio station gradually deteriorates or the station
presets are inoperative (no sound, 87.5 MHz is displayed, etc.).The vehicle is too far from the selected station’s transmitter, or no transmitter is present in the geographical area.► Activate the RDS function to allow the system to check for a more powerful transmitter in the area.The environment (hills, buildings, tunnels,
basement car parks, etc.) may block reception, including in RDS mode.This is a perfectly normal phenomenon, and is not indicative of an audio system malfunction.The aerial is absent or has been damaged (for example when going through an automatic car wash or in an underground car park).► Have the aerial checked by a dealer.The sound intermittently cuts out for 1 or 2 seconds in radio mode.During this brief sound cut-out, the RDS searches for another frequency giving better reception of the station.► Switch off the RDS function if the phenomenon occurs too frequently and always on the same route.
Media
The Bluetooth connection is cut.The battery in the peripheral device may not be sufficiently charged.► Charge the battery in the peripheral device.The message "USB device error" is displayed in the screen.

Ambient noise affects the quality of the telephone call.► Reduce ambient noise (close windows, turn down ventilation, slow down, etc.).The contacts are not listed in alphabetical order.Some telephones offer display options. Depending on the settings chosen, contacts can be transferred in a specific order.
► Modify the telephone directory display settings.
Settings
When the treble and bass settings are changed, the ambience is deselected.When the ambience is changed, the treble and bass settings are reset.Selecting an ambience imposes the treble and bass settings, and vice versa.► Modify the treble and bass or ambience settings to obtain the desired musical ambience.When the balance settings are changed, the distribution is deselected.When the distribution setting is changed, the balance settings are deselected.Selecting a distribution setting imposes the balance settings, and vice versa.► Modify the balance setting or the distribution setting to obtain the desired sound quality.There is a difference in sound quality between audio sources.To allow for optimal listening quality, the sound settings can be tailored to different audio
sources, which can generate audible differences when changing source.► Check that the sound settings are appropriate to the sources listened to. Adjust the sound functions to the middle position.When the engine is off, the system switches off after several minutes of use.When the engine is switched off, the system's operating time depends on the state of charge of
the battery.The switch-off is normal: the system automatically goes into energy economy mode and switches off to maintain an adequate charge in the battery.► Start the vehicle’s engine to increase the charge of the battery.
