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-
