2424-6. Driving tips
Use fluids that are appropriate to 
the prevailing outside temperatures.
• Engine oil
• Engine coolant/power control unit cool-
ant
• Washer fluid
 Have a service technician inspect 
the condition of the 12-volt battery.
 Have the vehicle fitted with four 
snow tires or purchase a set of tire 
chains for the front tires.
*
Ensure that all tires are the specified size 
and brand, and that chains match the size 
of the tires.
*: Tire chains cannot be mounted on vehi-
cles with 18-inch tires.
Perform the following according to the 
driving conditions:
 Do not try to forcibly open a window 
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 in excess of 75 mph (120 
km/h), regardless of the type of snow 
tires being used.
●Use snow tires on all, not just some 
wheels.
■Driving with tire chains (vehicles with 
17-inch tires)
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 30 mph (50 km/h), 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 LTA (Lane Tracing Assist) 
system.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow 
tires from Lexus dealers or legitimate tire 
retailers. 
This is because the removal and attach-
ment of snow tires affects the operation 
of the tire pressure warning valves and 
transmitters.

Maintenance and care
■Tire types
●Summer tires
Summer tires are high-speed perfor-
mance tires best suited to highway driv-
ing under dry conditions. Since summer 
tires do not have the same traction per-
formance as snow tires, summer tires are 
inadequate for driving on snow-covered 
or icy roads. For driving on snow-covered 
roads or icy roads, the use of snow tires is 
recommended. When installing snow 
tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide 
better traction in snow and to be ade-
quate for driving in most winter condi-
tions as well as for use year-round. All 
season tires, however, do not have ade-
quate traction performance compared 
with snow tires in heavy or loose snow. 
Also, all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway 
driving.
●Snow tires
For driving on snow-covered roads or icy 
roads, we recommend using snow tires. If 
you need snow tires,  select tires of the 
same size, construction and load capacity 
as the originally installed tires. Since your 
vehicle has radial tires as original equip-
ment, make sure your snow tires also 
have radial construction. Do not install 
studded tires without first checking local 
regulations for possible restrictions. 
Snow tires should be installed on all 
wheels. ( P.242)
■If the tread on snow tires wears down 
below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is 
lost.
WARNING
■When inspecting or replacing tires
Observe the following precautions to 
prevent accidents.
Failure to do so may cause damage to 
parts of the drivetrain  as well as danger-
ous 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 tow if your vehicle has a com-
pact spare tire installed.
●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.
NOTICE
■Driving on rough roads
Take particular care when driving on 
roads with loose surfaces or potholes.
These conditions may cause losses in tire 
inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving 
on rough roads may cause damage to 
the tires themselves, as well as the vehi-
cle’s wheels and body.
■Low profile tires (18-inch tires)
Low profile tires may cause greater dam-
age than usual to the tire wheel when 
sustaining impact from the road surface. 
Therefore, pay attention to the following:

When trouble arises
7-2.Steps to take in an emergency
The following may indicate a problem 
with your hybrid transmission. Contact 
your Lexus dealer or commercial tow-
ing service before towing.
If your vehicle needs to be 
t
owed
If towing is ne cessary, we recom-
mend having your vehicle towed by 
your Lexus dealer 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
Be sure to transport the vehicle with the 
front wheels raised or with all four wheels 
raised off the ground. If the vehicle is 
towed with the front wheels contacting 
the ground, the drivetrain and related 
parts may be damaged 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 (vehicles with a towing 
eyelet)
●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 power switch off. 
There is a possibility that the steering 
wheel is locked and cannot be oper-
ated.
■Installing towing eyelets to the vehi-
cle (vehicles with a towing eyelet)
Make sure that towing eyelets are 
installed securely. 
If not securely installed, towing eyelets 
may come loose during towing.
NOTICE
■To prevent damage to the vehicle 
when towing using a wheel-lift type 
truck
●Do not tow the vehicle from the rear 
when the power switch is off. The 
steering lock mechanism is not strong 
enough to hold the front wheels 
straight.
●When raising the vehicle, ensure ade-
quate ground clearance for towing at 
the opposite end of the raised vehicle. 
Without adequate clearance, the vehi-
cle could be damaged while being 
towed.
■To prevent damage to the vehicle 
when towing with a sling-type truck
Do not tow with a sling-type truck, either 
from the front or rear.
■To prevent damage to the vehicle 
during emergency towing (vehicles 
with a towing eyelet)
Do not secure cables or chains to the 
suspension components.

contact dealers before towing
