When driving
IS F_EE
Driving in the rain
Drive carefully when it is raining, because visibility will be reduced, the
windows may become fogged-up, and the road will be slippery.
Drive carefully when it starts to rain, because the road surface will be
especially slippery.
Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.
Engine speed while driving
In the following conditions, the engine speed may become high while driv-
ing. This is due to automatic up-shifting control or down-shifting implemen-
tation to meet driving conditions. It does not indicate sudden acceleration.
The vehicle is judged to be driving uphill or downhill
When the accelerator pedal is released
Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recom-
mended to observe:
For the first 300 km (186 miles):
Avoid sudden stops.
For the first 1000 km (621 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of
brake system needs bedding-down of the brake shoes periodically or when-
ever the parking brake shoes and/or drum are replaced. Have any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional, perform the bedding down.
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the avail-
ability of the correct fuel. (P. 4 7 4 )

2-4. Using other driving systems
IS F_EE
CAUTION
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 the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving
may cause an accident, resulting in death or serious injury. Exercise particu-
lar care when the indicator light flashes.
When TRC and VSC are off
Be especially careful and drive at a speed appropriate to the road conditions.
As these are systems to help enhance vehicle stability and driving force, do
not turn off TRC and VSC unless necessary.
Replacing tires
Make sure that all tires are of the designated size and total load capacity, and
of the same brand and tread pattern. In addition, make sure that the tires are
inflated to the recommended tire pressure level.
The ABS, VSC and TRC systems will not function correctly if different
tires are fitted on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional, for further information when replacing tires or
wheels.
Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will
affect the driving assist systems, and may cause the system to malfunction.

CAUTION
Luggage capacity and distribution
Observe the following precautions. Failure to do so will not only put load on
the tires, but also reduce steering and braking performance. This could lead
to an accident resulting in serious injury or even death.
Do not overload the vehicle.
Do not apply load to the vehicle unevenly.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropriate
to the prevailing weather conditions.
Pre-winter preparations
Use fluids that are appropriate to the prevailing outside
temperatures.
• Engine oil
• Engine coolant
• Washer fluid
Have a service technician inspect the level and specific
gravity of battery electrolyte.
Have the vehicle fitted with four snow tires.
Ensure that all tires are the specified size and the same brand.
Tire chains cannot be installed on 19-inch tires. Use the
specified type of tire chains and install them on the rear
tires only. Before installing the tire chains, change all four
tires and wheels to those of the specified size (tires: 225/
40R18, wheels: 18x8JJ +45 offset). For details, contact any
authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional.
Before driving the vehicle
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 windshield.
Remove any ice that has accumulated on the vehicle chas-
sis

Selecting tire chains
Tire chains can be mounted on 18-inch tires. They cannot be
mounted on 19-inch tires. Use the correct tire chain size when
mounting the snow chains.
Chain size is regulated for each tire size.
Side chain
(3 mm [0.12 in.] in diameter)
Cross chain
(4 mm [0.16 in.] in diameter)
Regulations on the use of snow chains
Regulations regarding the use of tire chains vary according to
location and type of road. Always check local regulations before
installing chains.
Install the chains on the rear tires.
Retighten the chains after driving 0.5 - 1.0 km (1/4 - 1/2 mile).
When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed
suitable to road conditions.
When parking the vehicle
Park the vehicle and move the shift lever to P without setting
the parking brake. The parking brake may freeze up, prevent-
ing it from being released. If necessary, block the wheels to
prevent inadvertent sliding or creeping.

CAUTION
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing 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 at speeds in excess of the speed limit or the speed limit spec-
ified for the 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.
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 tire chains being
used or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.
Avoid sudden turns and braking, as use of chains may adversely affect
vehicle handling.
Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
