Before driving
1-6. Theft deterrent system
Engine immobilizer system
: If equipped
■System maintenance
The vehicle has a maintenance-free type engine immobilizer system.
■ Conditions that may cause the system to malfunction
● If the key is in contact with a metallic object
● If the key is in close proximity to or touching a key to the security system
(key with a built-in transponder chip) of another vehicle
The vehicle’s keys have built-in tr ansponder chips that prevent the
engine from starting if the key has not been previously registered in
the vehicle’s on-board computer.
Never leave the keys inside the vehicle when you leave the vehicle.
The indicator light flashes after
the key has been removed
from the engine switch to indi-
cate that the system is operat-
ing.
The indicator light stops flash-
ing after the registered key
has been inserted into the
engine switch to indicate that
the system has been can-
celed.

118 1-6. Theft deterrent system
■System maintenance
The vehicle has a maintenance-free type alarm system.
■ Items to check before locking the vehicle
To prevent unexpected triggering of the alarm and vehicle theft, make sure
of the following.
●Nobody is in the vehicle.
● The windows and moon roof are closed before the alarm is set.
● No valuables or other personal items are left in the vehicle.
■ Triggering of the alarm

When driving
NOTICE
■
To prevent the water damage
●Take all necessary safety measures to ensure that water damage to the
engine or other components does not occur.
● Water entering the engine air intake will cause severe engine damage.
● Water entering the automatic transmission will cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ulti-
mately damage.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, transmission and
transfer case, reducing the gear oil’s lubricating qualities.
■ When you drive through water
If driving through water, such as when crossing shallow streams, first check
the depth of the water and the bottom of the river bed for firmness. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
●Sand and mud that has accumulat ed in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.

290 2-5. Driving information
●The vehicle remains level when a loaded or unloaded trailer is hitched.
Do not drive if the vehicle 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
towing purposes.
● Depress TOW/HAUL button (if equipped)
■ Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential 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 s\
tart
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.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. (See “Owner’s Warranty Information Booklet”
or “Scheduled Maintenance Guide” /“Owner’s Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km) of trailer towing.
■ If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
• Begin releasing the accelerator pedal immediately but very gradually to reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. (if enabled, Trailer Sway Control can also help to
stabilize the vehicle and trailer.)
