WARNING
Any of the following conditions may result in an accident which could cause death or seri-
ous injury: ■
The Multi Terrain ABS does not operate effectively when ●
The limits of tire gripping performance have been exceeded (such as excessively
worn tires on a snow covered road). ●
The vehicle hydroplanes while driving at high speed on a wet or slick road.■
Stopping distance when the Multi Terrain ABS is operating may exceed that of nor-
mal conditions
The Multi Terrain ABS is not designed to shorten the vehicle’s stopping distance.
Always maintain a safe distance from the vehicle in front of you, especially in the follow-
ing situations. ●
When driving on dirt, grav el or snow-covered roads●

surfaces, even if the Acti ve TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.■
If the hill-start assist control does not operate effectively
Do not overly rely on the hill-start assist control. The hill-start assist control may not
operate effectively on steep inclines and roads covered in ice. ■
When Active TRAC, VSC and Tr ailer Sway Control are off
Be especially careful and drive at a speed appropriate to the road conditions. As these

Driving WARNING ■
Replacing tires
Make sure that all tires are of the same si ze, brand, tread pattern and total load capac-
ity. In addition, make sure that the tires are inflated to the specified tire pressure level.
The Multi Terrain ABS, Active TRAC, VSC an d Trailer Sway Control will not function
correctly if different tires are fitted on the vehicle.
Contact your Lexus dealer for further in formation when replacing tires or wheels.■
Handling of tires and suspension
Using tires with any kind of problem or modi fying the suspension w ill affect the driving
assist systems, and may caus e the system to malfunction.■
Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situations.
Depending on many factors such as the condit ions of the vehicle, trailer, road surface,
and driving environment, the Trailer Sway Control system may not be effective. Refer to
your trailer owner’s manual for information on how to tow your trailer properly. ■
If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury. ●
Firmly grip the steering wh eel. Steer straight ahead.
Do not try to control trailer sway ing 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. ( P. 207)

Winter driving tips ●
Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine coolant
• Washer fluid ●
Have a service technician inspect the condition of the battery. ●
Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the rear tires.
*Ensure that all tires are the same size and br and, and that chains match the size of the
tires.
* : Tire chains cannot be mounted on vehicles with 21-inch tires
Perform the following according 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 me lt the ice. Wipe away the water imme-
diately to prevent it from freezing. ●
To ensure proper operation of the c limate 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 accumulated on
the exterior lights, vehicle’s roof, chassi s, around the tires or on the brakes.●

Driving Accelerate the vehicle slowly, keep a sa fe distance between you and the vehicle
ahead, and drive at a reduced spee d suitable to road conditions.●
Park the vehicle and move the shift lever to P without setting the parking
brake. The parking brake may freeze up, preventing it from being released. If
the vehicle is parked without setting the parking brake, make sure to block the
wheels.
Failure to do so may be dangerous because it may cause the vehicle to move
unexpectedly, possibly leading to an accident. ●
If the vehicle is parked without setting the parking brake, confirm that the shift
lever cannot be moved out of P
* .When the parking brake is in automatic mo de, release the parkin g brake after shifting
the shift lever to P. ( P. 224)
* : The shift lever will be locked if it is attempted to be shif ted from P to any other position
without depressing the brake pedal. If the sh ift lever can be shifte d from P, there may
be a problem with the shift lock system. Have the vehicle inspected by your Lexus
dealer immediately.
Vehicles with 20-inch tires
Use the correct tire chain size when mounting the snow chains.
Chain size is regulated for each tire size.
Side chain
(0.20 in. [5 mm] in diameter)
Cross chain
(0.25 in. [6.3 mm] in diameter)
Vehicles with 21-inch tires

Regulations regarding the use of tire chains vary depending on location and type
of road. Always check local regu lations before installing chains.■
Tire chain installation
Observe the following precautions when installing and removing chains: ●
Install and remove tire chains in a safe location. ●
Install tire chains on the rear tires. Do not install tire chains on the front tires.●
Install tire chains on rear tires as tightly as possible. Retighten chains after driving 1/4 -
1/2 mile (0.5 - 1.0 km). ●
Install tire chains following the instru ctions provided with the tire chains.Regulations on the use of tire chains
WARNING ■
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehi cle control and cause death or serious injury.●
Use tires of the specified size. ●
Maintain the recommended level of air pressure.●
Do not drive in excess of 75 mph (120 km/h ), regardless of the type of snow tires
being used. ●
Use snow tires on all, not just some wheels. ■
Driving with tire chains (vehicles with 20-inch tires)
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury. ●
Do not drive in excess of the speed limit specified for the ti re chains being used, or 30
mph (50 km/h), whichever is lower. ●
Avoid driving on bumpy road surfaces or over potholes.●
Avoid sudden acceleration, abrupt steering, sudden braking and shifting operations
that cause sudden engine braking. ●
Slow down sufficiently before entering a cu rve to ensure that vehicle control is main-
tained. ●
Do not use LDA (Lane Departure Alert) system. (if equipped) ■
When installing tire chains (vehicles with 20-inch tires)
Turn off the vehicle height control.
The vehicle height may change due to the automatic leveling function and you may
catch part of your body in the vehicle, resulting in an accident. ( P. 304)

Off-road precautions ●
Specific design characteristics give it a higher center of gravity than ordinary
passenger cars. This vehicle design feature causes this type of vehicle to be
more likely to rollover. And, utility vehi cles have a significantly higher rollover
rate than other types of vehicles. ●
An advantage of the higher ground cl earance is a better view of the road
allowing you to anticipate problems. ●
It is not designed for cornering at the same speeds as ordinary passenger cars
any more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Therefore, sharp turns at excessive speeds may
cause the vehicle to rollover.This vehicle belongs to the utility vehicl e class, which has higher ground clear-
ance and narrower tread in relation to the height of its center of gravity to
make it capable of performing in a wi de variety of off-road applications.
