Driving
Control your speed and keep at a constant speed. Also, before stopping
at a toll booth or similar, allow plenty of time to release the accelerator and
gently apply the brakes. A greater am ount of electrical energy can be
retained when slowing down.
Use the air conditioning only when ne cessary. Doing so can help control
excessive gasoline consumption.
In summer: In high temperatures, use th e recirculated air mode. Doing so
will help to reduce the burden on th e air conditioner and reduce fuel con-
sumption as well.
In winter: Because the gasoline engine will not automatically cut out until
the gasoline engine and the interior of the vehicle are warm, it will con-
sume fuel. Also, fuel consumption can be improved by avoiding overuse of
the heater.
Make sure to check the tire inflati on pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large am ounts of friction, their use on dry
roads can lead to poor fuel consumptio n. Use a tire that is appropriate for
the season.
Carrying heavy luggage can lead to poor fuel consumption. Avoid carry-
ing unnecessary luggage. Installing a la rge roof rack can also cause poor
fuel consumption.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside temperatures. • Engine oil
• Engine coolant
• Power control unit coolant (hybrid vehicles)
• Washer fluid
●Have a service technician inspect th e condition of the 12-volt battery.
●Have the vehicle fitted with four sno w tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the specified size and brand, and that chains match the
size of the tires.
Carry out the necessary preparati ons and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropriate
to the prevailing weather conditions.

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 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 wind-
shield.
●Check for and remove any excess ice or snow that may have accumu-
lated on the exterior lights, vehicle’s roof, chassis, around the tires or on
the brakes.
●Remove any snow or mud from the bo ttom of your shoes before getting
in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and the
vehicle ahead, and drive at a reduced speed 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 necessary, block the wheels to prevent inadvertent sliding or
creeping.

Use the correct tire chain size when mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
0.12 in. (3 mm) in diameter
0.39 in. (10 mm) in width
1.18 in. (30 mm) in length
Cross chain
0.16 in. (4 mm) in diameter
0.55 in. (14 mm) in width
0.98 in. (25 mm) in length
Regulations regarding the use of tire chains vary depending on location
and type of road. Always check loca l regulations 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 front tires. Do not install tire chains on the rear tires.
●Install tire chains on front tires as tightl y as possible. Retighten chains after driving
1/4 1 /2 mile (0.5 1.0 km).
●Install tire chains following the instructions provided with the tire chains.

CAUTION
■Driving 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.
●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
Observe the following precautions to reduce the risk of accidents.
Failure 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 tire 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 opera-
tions that cause sudden engine braking.
●Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.
●Do not use LDA (Lane Departure Alert) system.

NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers 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.
■Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly when
tire chains are fitted.
■When standing the windshield wipers up
Raise the wipers in line with the windshield. ( P. 344)
Failure to do so may result in dama ge to the wipers and/or the hood.
