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-

rized Lexus dealers or repairers or other duly qualified and equipped profes-
sionals. For repairs and services covered by your warranty, please visit an
authorized Lexus dealer or repairer, who will use genuine Lexus parts in
repairing any difficulties you may encounter. There can also be advantages
in utilizing authorized Lexus dealers or repairers for non-warranty repairs

assist you with any difficulties you may encounter.
Your Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional service department will perform all of the scheduled maintenance
on your vehicle - reliably and economically due to their experience with
Lexus vehicles.
Does your vehicle need repair?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air
conditioning after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon monox-
ide leak. Drive with the windows open and have the exhaust system
checked immediately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire
wear
Vehicle pulls to one side when driving straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional, as
soon as possible. Your vehicle may need adjustment or repair.

If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, engine coolant filler cap, radiator cap,
drain cock and water pump.
If you cannot find a leak, have any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for
leaks in the cooling system.
Coolant selection
Only use “Toyota Super Long Life Coolant” or similar high-quality eth-
ylene glycol-based non-silicate, non-amine, non-nitrite, and non-borate
coolant with long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50%
deionized water. (Enabled: -35C [-31F])
For more details about engine coolant, contact any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional.
CAUTION
When the engine is hot
Do not remove the radiator cap (IS250), or the coolant reservoir cap (IS220d
and IS200d).
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
When adding engine coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
If you spill coolant
Be sure to wash it off with water to prevent damage to parts or paint.
