4-1. Before driving
■Matching trailer ball height to trailer coupler height
■ Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 600)
● Trailer tires are inflated according to the trailer manufacturer’s recommen-
dation.
● All trailer lights work as required by law.
● All lights work each time you connect them.
● The trailer ball is set at the proper height for the coupler on the trailer.
● The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for improper tongue weight,
overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for tow-
ing purposes.
■ Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differ ential or wheel bearing), Toyota rec-
ommends that you do not tow a trailer until the vehicle has been driven for
over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start
towing. However, for the next 500 miles (800 km), drive the vehicle at a speed
of less than 50 mph (80 km/h) when towing a trailer, and avoid full throttle
acceleration. No matter which class of tow hitch
applies, for a safe trailer hookup, the
trailer ball setup on must be proper height
for the coupler on the trailer.

4-2. Driving procedures
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 while driving
If the vehicle begins to slide due to engine failure or other circumstances, do
not lock or open the doors until the vehicle reaches a safe and complete
stop. Activation of the steering lock in this circumstance may lead to an
accident, resulting in death or serious injury.
■ Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
press and hold the engine switch for more than 2 seconds, or press it briefly
3 times or more in succession. ( P. 529)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine off while driving will not cause loss of steering or
braking control, but the power assist to these systems will be lost. This will
make it more difficult to steer and brake, so you should pull over and stop
the vehicle as soon as it is safe to do so.
NOTICE
■ To prevent battery discharge
● Do not leave the engine switch in ACCESSORY or IGNITION ON mode
for long periods of time without the engine running.
● If the indicator on the engine switch is illuminated, the engine switch is not
off. When exiting the vehicle, always check that the engine switch is off.
● Do not stop the engine when the shift lever is in a position other than P. If
the engine is stopped in another shift lever position, the engine switch will
not be turned off but instead be turned to ACCESSORY mode. If the vehi-
cle is left in ACCESSORY mode, battery discharge may occur.
■ When starting the engine
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.
■ Symptoms indicating a malfunction with the engine switch
If the engine switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction.
Contact your Toyota dealer immediately.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician ins pect the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
Perform the following accordin g to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, ve hicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.
