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

Selecting tire chains
Tire chains can be mounted on 16- and 17-inch tires. They cannot
be mounted on 18-inch tires. Use the correct tire chain size when
mounting the tire 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 tire 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.
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 (automatic
transmission) or 1 or R (manual transmission) 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.

4-3. Do-it-yourself maintenance
IS250/220d/200d_EE
When to replace your vehicle’s tires
Tires should be replaced if:
You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric or bulges indicating internal damage
A tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Tire life
Any tire over 6 years old must be checked by a qualified technician even if
it has seldom or never been used or damage is not obvious.
If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of snow tires is lost.
Low profile tires (models not equipped with 16-inch tires)
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains
* on snowy and/or icy roads and
drive carefully at a speed appropriate for road and weather conditions.
*: Tire chains cannot be mounted on 18-inch tires.
CAUTION
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train, as well as dan-
gerous handling characteristics, which may lead to an accident resulting in
death or serious injury.
Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
Do not use tire sizes other than those recommended by Lexus.
Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
Do not mix summer, all season and snow tires.
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.

Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of han-
dling control.
Wheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diame-
ter, rim width, and inset
*.
Replacement wheels are available at any authorized Lexus
dealer or repairer, or another duly qualified and equipped pro-
fessional.
*: Conventionally referred to as “offset”.
Lexus does not recommend using:
Wheels of different sizes or types
Used wheels
Bent wheels that have been straightened
Aluminum wheel precautions
Use only Lexus wheel nuts and wrenches designed for use
with your aluminum wheels.
When rotating, repairing or changing your tires, check that
the wheel nuts are still tight after driving 1600 km (1000
miles).
Be careful not to damage the aluminum wheels when using
tire chains.

If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission.
Contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional, before towing.
The engine is running, but the vehicle will not move.
The vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available, in an emergency your vehicle may
be temporarily towed using a cable or chain secured to the emer-
gency towing eyelet(s). This should only be attempted on hard,
surfaced roads for short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
If towing is necessary, we recommend having your vehicle towed by
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, such as a commercial towing service, using a
lift-type truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all state/provin-
cial and local laws.
If towing from the rear, the vehicle's front wheels and axles must be in
good condition. (P. 463)
If they are damaged, use a towing dolly or flat bed truck.
