4-6. Driving tips
Driving
Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
•Engine coolant
• Power control unit coolant (LC500h)
•Washer fluid
 Have a service technician inspect
the condition of the 12-volt battery.
 Have the vehicle fitted with four
snow tires.
Ensure that all tires are the specified size
and the same brand.
 Tire chains can only be installed on
the rear tires. However, tire chains
cannot be installed on 275/35RF21
or 275/40RF20 rear tires.
Before installing tire ch ains, change all four
tires and wheels to those of the specified
size for use with tire chains (front tires:
245/45RF20, rear tires: 245/45RF20,
wheels: 20 x 8 1/2 J 25 inset). Use the
specified type of tire chains and install
them on the rear tires only.
For details, contact any authorized Lexus
retailer or Lexus authorized repairer, or
any reliable repairer.
Winter driving tips
Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.
Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri- ous 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 specified 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.
Failure 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), which-
ever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
●Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.
●Do not use LKA (Lane-Keeping Assist) system. (if equipped)

4-6. Driving tips
Driving
Vehicles with front and rear tires of
the same size
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 diam-
eter)
Cross chain (4 mm [0.16 in.] in
diameter)
Vehicles with front and rear tires of
differing sizes
Tire chains cannot be mounted.
Snow tires should be used instead.
Regulations regarding the use of tire
chains vary dependin g on location and
type of road. Always check local regu-
lations before installing chains.
■Tire chain installation
Observe the following precautions when
installing and removing chains:
●Install and remove tire chains in a safe location.
●Install tire chains on the rear tires. Do not install tire chains on the front tires.
●Install tire chains on rear tires as tightly as possible. Retighten chains after driving 0.5 - 1.0 km (1/4 - 1/2 mile).
●Install tire chains following the instruc-tions provided with the tire chains.
To enable the windshield wipers to be
lifted when heavy snow or icy condi-
tions are expected, change the rest
position of the windshield wipers from
the retracted position below the hood
to the service position using the wiper
lever. ( P.198)

6-3. Do-it-yourself maintenance
When replacing wheels, care should
be taken to ensure that they are equiv-
alent to those removed in load capac-
ity, diameter, rim width and inset*.
Replacement wheels are available at
any authorized Lexus retailer or Lexus
authorized repairer, or any reliable
repairer.
*: Conventionally referred to as offset.
Lexus does not recommend using the
following:
 Wheels of different sizes or types
 Used wheels
 Bent wheels that have been straight-
ened
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and trans-
mitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, tire pres- sure warning valves and transmitters must be installed. ( P.335)Use only Lexus wheel nuts and
wrenches designed for use with
your aluminum wheels.
 When rotating, repairing or chang-
Wheels
If a wheel is bent, cracked or heavily
corroded, it should be replaced.
Otherwise, the tire may separate
from the wheel or cause a loss of
handling control.
Wheel selection
WARNING
■When replacing wheels
●Do not use wheels that are a different
size from those recommended in the Owner’s Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leaking
wheel which is designed for a tubeless tire. Doing so may result in an acci-dent, causing death or serious injury.
■Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an acci-dent.
NOTICE
■Replacing tire pressure warning
valves and transmitters
●Because tire repair or replacement
may affect the tire pressure warning valves and transmitters, make sure to have tires serviced by any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer or other qualified service shop. In addi-
tion, make sure to purchase your tire pressure warning valves and transmit-ters at any authorized Lexus retailer or
Lexus authorized repairer, or any reli- able repairer.
●Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valves and trans- mitters may not work properly with non-genuine wheels.

7-2. Steps to take in an emergency
7-2.Steps to take in an emergency
If your vehicle needs to be
towed
If towing is necessary, we recom-
mend having your vehicle towed by
any authorized Lexus retailer or
Lexus authorized repairer, or any
reliable repairer or commercial
towing service, using a wheel-lift
type truck or flatbed truck.
Use a safety chain system for all
towing, and abide by all state/pro-
vincial and local laws.
WARNING
Observe the following precautions. Failure to do so may result in death or
serious injury.
■When towing the vehicle
LC500: Be sure to transport the vehicle with all four wheels raised off the ground. If the vehicle is towed with the tires con-
tacting the ground, the drivetrain and related parts may be damaged or an accident may occur due to a change in
direction of the vehicle.
LC500h: Be sure to transport the vehi- cle with all four wheels raised off the
ground. If the vehicle is towed with the tires contacting the ground, the drive-train and related parts may be damaged,
an accident may occur due to a change in direction of the vehicle or electricity generated by the operation of the motor
may cause a fire to occur depending on the nature of the damage or malfunction.
■While towing
●When towing using cables or chains, avoid sudden starts, etc. which place excessive stress on the towing eyelets,
cables or chains. The towing eyelets, cables or chains may become dam-aged, broken debris may hit people,
and cause serious damage.
●Do not turn the engine switch off.This may lead to an accident as the
rear wheels will be locked by the park- ing lock. Also, there is a possibility that the steering wheel is locked and can-
not be operated.
■Installing towing eyelets to the vehi- cle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.
