WARNING
QBefore using LTA system
ODo not rely solely upon the LTA
system. The LTA system does not automatically drive the vehicle or reduce the amount of attention that
must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving
safely by paying careful attention to the surrounding conditions and operating the steering wheel to cor-
rect the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as from
driving for a long period of time.
OFailure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.
OWhen not using the LTA system, use the LTA switch to turn the sys-
tem off.
QSituations unsuitable for LTA
system
In the following situations, use the LTA switch to turn the system off.
Failure to do so may lead to an acci- dent, resulting in death or serious injury.
OVehicle is driven on a road surface which is slippery due to rainy
weather, fallen snow, freezing, etc.
OVehicle is driven on a snow-cov-
ered road.
OWhite (yellow) lines are difficult to
see due to rain, snow, fog, dust, etc.
OVehicle is driven in a temporary lane or restricted lane due to con-struction work.
OVehicle is driven in a construction zone.
OA spare tire, tire chains, etc. are equipped.
OWhen the tires have been exces-sively worn, or when the tire infla-tion pressure is low.
OWhen your vehicle is towing a trailer or during emergency towing
QPreventing LTA system malfunc-tions and operations performed
by mistake
ODo not modify the headlights or place stickers, etc. on the surface of
the lights.
ODo not modify the suspension etc. If
the suspension etc. needs to be replaced, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
ODo not install or place anything on
the hood or grille. Also, do not install a grille guard (bull bars, kan-garoo bar, etc.).
OIf your windshield needs repairs, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
QConditions in which functions may not operate properly
In the following situations, the func-
tions may not operate properly and the vehicle may depart from its lane. Drive safely by always paying careful
attention to your surroundings and operate the steering wheel to correct the path of the vehicle without relying
solely on the functions.

3985-6. Driving tips
5-6.Driving tips
Use fluids that are appropriate to
the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Power control unit coolant
• Washer fluid
 Have a service technician
inspect the condition of the 12-
volt 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.*
*: Tire chains cannot be mounted on
vehicles with 235/55R19 tires.
Winter driving tips
Carry out the necessary prepa-
rations and inspections before
driving the vehicle in winter.
Always drive the vehicle in a
manner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
WARNING
QDriving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or serious injury.
OUse tires of the specified size.
OMaintain the recommended level of air pressure.
ODo not drive at speeds in excess of the speed limit or the speed limit specified for the snow tires being
used.
OUse snow tires on all, not just some
wheels.
QDriving with tire chains (except
235/55R19 tires)
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehi- cle being unable to be driven safely, and may cause death or serious
injury.
ODo not drive in excess of the speed
limit specified for the tire chains being used, or 50 km/h (30 mph), whichever is lower.
OAvoid driving on bumpy road sur-faces or over potholes.
OAvoid sudden acceleration, abrupt steering, sudden braking and shift-
ing operations that cause sudden engine braking.
OSlow down sufficiently before enter-ing a curve to ensure that vehicle control is maintained.
ODo not use LTA (Lane Tracing Assist) system (if equipped).
NOTICE
QRepairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer or legitimate tire retailers.
This is because the removal and attachment of snow tires affects the operation of the tire pressure warning
valves and transmitters.

4005-6. Driving tips
Vehicles with 225/60R18 tires
Use the correct tire chain size when
mounting the tire chains. Chain size
is regulated for each tire size.
Side chain:
3 mm (0.12 in.) in diameter
10 mm (0.39 in.) in width
30 mm (1.18 in.) in length
Cross chain:
4 mm (0.16 in.) in diameter
14 mm (0.55 in.) in width
25 mm (0.98 in.) in length
Vehicles with 235/55R19 tires
Tire chains cannot be mounted.
Snow tires should be used instead.
Regulations regarding the use of
tire chains vary depending on loca-
tion and type of road. Always check
local regulations before installing
chains.
QTire chain installation
Observe the following precautions when installing and removing chains:
OInstall and remove tire chains in a safe location.
OInstall tire chains on the front tires only. Do not install tire chains on the rear tires.
OInstall tire chains on front tires as tightly as possible. Retighten chains
after driving 0.5 - 1.0 km (1/4 - 1/2 mile).
OInstall tire chains following the instruc-tions provided with the tire chains.
QConsumption of fuel and electricity
In cold temperatures, resistance of the
parts of a vehicle (transmission, tires, etc.) generally increases, resulting in increase of energy consumption. As a
result, fuel economy is likely to decrease.
Consumption of fuel and electricity of
this vehicle is also likely to become worse in cold temperatures.

QRoutine tire inflation pressure
checks
The tire pressure warning system does
not replace routine tire inflation pressure
checks. Make sure to check tire inflation
pressure as part of your routine of daily
vehicle checks.
QTire inflation pressure
OIt may take a few minutes to display
the tire inflation pressure after the
power switch is turned to ON. It may
also take a few minutes to display the
tire inflation pressure after inflation
pressure has been adjusted.
OTire inflation pressure changes with
temperature. The displayed values
may also be different from the values
measured using a tire pressure
gauge.
QSituations in which the tire pres-
sure warning system may not oper-
ate properly
OIn the following cases, the tire pres-
sure warning system may not operate
properly.
• If non-genuine Toyota wheels are
used.
• A tire has been replaced with a tire
that is not an OE (Original Equipment)
tire.
• A tire has been replaced with a tire
that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-supported run-flat tire is
equipped.
• If a window tint that affects the radio
wave signals is installed.
• If there is a lot of snow or ice on the
vehicle, particularly around the wheels
or wheel housings.
• If the tire inflation pressure is
extremely higher than the specified
level.
• If wheels without tire pressure warning
valves and transmitters are used.
• If the ID code on the tire pressure
warning valves and transmitters is not
registered in the tire pressure warning
computer.
OPerformance may be affected in the
following situations.
• Near a TV tower, electric power plant,
gas station, radio station, large dis-
play, airport or other facility that gen-
erates strong radio waves or electrical
noise
• When carrying a portable radio, cellu-
lar phone, cordless phone or other
wireless communication device
If tire position information is not cor-
rectly displayed due to the radio wave
conditions, the display may be cor-
rected by driving and changing the
radio wave conditions.
