When driving
IS250/220d/200d_EE
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 or purchase a
set of tire chains for the rear tires.
Ensure that all tires are the specified size and the same brand, and
that chains match the size of the tires.
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.

Engine oil consumption
The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
A new engine consumes more oil.
When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level
accurately.
Oil consumption: Max. 1.0 L per 1,000 km (1.1 qt./600 miles, 0.9 Imp.
qt./600 miles)
If your vehicle consumes more than 1.0 L (1.1 qt., 0.9 Imp. qt.) every
1000 km (600 miles), contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
After changing the engine oil (IS220d and IS200d)
The oil change system should be reset. Perform the following procedures:
Switch the display to the odometer (P. 171) when the engine is
running.
Turn the “ENGINE START STOP” switch OFF.
While pressing the trip meter reset button, set the “ENGINE
START STOP” switch to IGNITION ON mode (but do not start the
engine because otherwise the reset mode will be cancelled). Con-
tinue to press and hold the button until the trip meter displays
“000000”.
