WARNI NG
ASR / DSCThese systems enhance safety during normal driving, but should not encourage the driver to take extra risks or drive at high speed.It is in conditions of reduced grip (rain, snow, ice) that the risk of loss of grip increases. It is therefore important for your safety to keep these systems activated in all conditions, and particularly in difficult conditions.
Correct operation of these systems depends on compliance with the manufacturer's recommendations relating to the wheels (tyres and rims), braking and electronic components, as well as the assembly and repair procedures used by TOYOTA dealers.The use of snow tyres is recommended, to ensure that these systems remain effective in winter conditions. All four wheels must be fitted with tyres approved for the vehicle.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the vehicle or trailer snaking.
Operation
The system is activated automatically when the ignition is switched on.The electronic stability control system (ESC) must not have any faults.At speeds between 60 and 160 km/h (37 and 99 mph), if the system detects oscillating trailer movements (snaking), it acts on the brakes to stabilise the trailer and, if necessary, reduces engine power to slow the vehicle.This warning lamp flashes on the instrument panel and the brake lamps light up to draw attention to this corrective action.For information on weights and towed loads, refer to the Engine Technical Data and Towed Loads section or your vehicle’s registration certificateTo ensure safe driving with a Towing device,
refer to the corresponding section.
Malfunction
If a fault occurs, this warning lamp comes on in the instrument panel, accompanied by a message and an audible signal.If you wish to continue towing a trailer, reduce your speed and drive carefully!Contact a TOYOTA dealer or a qualified workshop to have the system checked.
WARNI NG
The trailer stability assist system offers enhanced safety in normal driving, provided that the recommendations on towing a trailer are observed. It should not encourage the driver to take risks, such as towing a trailer in adverse operating conditions (overloading, failure to observe the trailer nose weight, worn or under-inflated tyres, faulty braking system, etc.), or to drive at excessive speeds.In certain cases, the system may not detect trailer snaking, particularly with a light trailer.When driving on slippery or poor surfaces, the system may not be able to prevent sudden trailer snaking.

On leaving the flooded road, as soon as safety conditions allow, make several light brake applications to dry the brake discs and pads.If in doubt about the state of your vehicle, contact a TOYOTA dealer or a qualified workshop.
In case of towing
WARNI NG
Driving with a trailer places greater demands on the towing vehicle and requires extra care from the driver.
NOTIC E
Respect the maximum towable weights.At altitude: reduce the maximum load by 10% per 1,000 metres (3,280 ft) of altitude; the density of the air decreases with altitude and the performance of the engine reduces.
WARNI NG
New vehicle: do not pull a trailer before having driven at least 1,000 kilometres (620 miles).
NOTIC E
If the outside temperature is high, let the engine idle for 1 to 2 minutes after the vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the heaviest items are as close as possible to the axle and the nose weight (at the point where it joins your vehicle) approaches the maximum permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing vehicle and of the trailer, observing the recommended pressures.
Lighting
► Check the electrical signalling on the trailer and the headlamp beam height of your vehicle.
NOTIC E
If a genuine TOYOTA towing device is used, the rear parking sensors will be deactivated automatically to avoid the audible signal.
When driving
Cooling
Towing a trailer uphill increases the temperature of the coolant. The maximum towable load depends on the gradient and the exterior temperature. The cooling capacity of the fan does not increase with engine speed.► Reduce speed and lower the engine speed, so as to limit the heating-up.In all cases, pay attention to the coolant temperature.If this warning lamp and the STOP warning lamp come on, stop the vehicle and switch off the engine as soon as possible.
Brakes
Braking distances are increased when towing a trailer. To avoid overheating of the brakes, the use of engine braking is recommended.
Side wind
Bear in mind the increased susceptibility to the wind that the vehicle will have.

Towing device
Load distribution► Distribute the load in the trailer so that the heaviest items are as close as possible to the axle and the nose weight approaches the maximum permitted without exceeding it.Air density decreases with altitude, thus reducing engine performance. The maximum towed load must be reduced by 10 % for every 1,000 metres (3,280 ft) of altitude.
NOTIC E
Use towing devices and their unmodified harnesses approved by TOYOTA. It is recommended that the installation be performed by a TOYOTA dealer or a qualified workshop.If the towing device is not fitted by a TOYOTA dealer, it must still be fitted in accordance with the vehicle manufacturer's instructions.Certain driving assistance or manoeuvring assistance functions are automatically disabled if an approved towbar is used.
WARNI NG
Observe the maximum authorised towable weight, indicated on your vehicle's registration certificate, the manufacturer's label as well as in the Technical data section of this guide.Complying with the maximum authorised nose weight (towball) also includes the use of accessories (bicycle carriers, tow boxes, etc.).
