Maintenance and
care
Use only Lexus wheel nuts and
wrenches designed for use with
your aluminum wheels.
When rotating, repairing or chang-
ing your tires, check that the wheel
nuts are still tight after driving 1000
miles (1600 km).
Be careful not to damage the alumi-
num wheels when using tire chains.
Use only Lexus genuine balance
weights or equivalent and a plastic
or rubber hammer when balancing
your wheels.
WARNING
●
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 your Lexus
dealer or other qualified service shop.
In addition, make sure to purchase
your tire pressure warning valves and
transmitters at your Lexus dealer.
●
Ensure that only genuine Lexus wheels
are used on your vehicle.
Tire pressure warning valves and
transmitters may not work properly
with non-genuine wheels.

WARNING
■
If the engine has to be turned off while
driving
Turning the engine off while driving will
not cause loss of steering or braking con-
trol. However, power assist for these sys-
tems may be lost making it difficult to
steer or brake before stopping the vehi-
cle depending on the remaining charge
in the battery or usage conditions. Decel-
erate as much as possible before turning
off the engine.
If the vehicle is submerged
or water on the road is rising
This vehicle is not designed to be
able to drive on roads that are
deeply flooded with water. Do not
drive on roads where the roads may
be submerged or the water may be
rising. It is dangerous to remain in
the vehicle, if it anticipated that the
vehicle will be flooded or set a drift.
Remain calm and follow the follow-
ing.

Towing with a wheel-lift type
truck
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 all
four wheels raised off the ground. If the
vehicle is towed with the tires contacting
the ground, the drivetrain or related
parts may be damaged, the vehicle may
fly off the truck.

7-2. Steps to take in an emergency
When using a flat-bed truck to trans-
port the vehicle, use tire strapping
belts. Refer to the owner’s manual of
the flat-bed truck for the tire strapping
method.
In order to suppress vehicle movement
during transportation, set the parking
brake and turn the engine switch off.
If a tow truck is not available in an
emergency, your vehicle may be tem-
porarily towed using cables or chains
secured to the emergency towing
hook. This should only be attempted on
hard surfaced roads for at most 50
miles (80 km) at under 18 mph (30
km/h).
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.
1
Securely attach cables or chains to
the towing hook.
Take care not to damage the vehicle body.
2
Enter the vehicle being towed and
start the engine.
If the engine does not start, turn the engine
switch to ON.
3
Put the four-wheel drive control
switch in “H4”. (The center differ-
ential is unlocked.)
4
Vehicles with AHC: Change the
vehicle height to N (standard)
mode and end the vehicle height
operation. (
5
Shift the shift lever to N and release
the parking brake.

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 engine 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.

While towing
If the engine is not running, the power assist
for the brakes and steering will not function,
making steering and braking more difficult.
■
If the cables or chains touch the bumper
If the cables or chains touch the bumper
due to the angle at which the cables or
chains are hanging, remove the cover (if
equipped) on the bumper.
• Remove the bolt, pull the cover toward
you, and then detach the 2 claws.
WARNING
Observe the following precautions. Fail-
ure to do so may result in death or seri-
ous injury.
■
While towing
●
When towing using cables or chains,
avoid sudden starts, etc. which place
excessive stress on the towing hook,
cables or chains. The towing hook,
cables or chains may become dam-
aged, broken debris may hit people,
and cause serious damage.
●
Vehicles with AHC: Make sure to turn
off the AHC. Otherwise, the vehicle
height may change and part of your
body may be caught under the vehicle,
possibly causing injury. (
●
Do not turn the engine switch off.
There is a possibility that the steering
wheel is locked and cannot be oper-
ated.
NOTICE
■
To prevent damage to the vehicle
during emergency towing
Do not secure cables or chains to the
suspension components.
■
When towing a vehicle equipped with
a Stop & Start system
If it is necessary to tow the vehicle with all
4 wheels on the ground, perform the fol-
lowing procedure before towing the
vehicle, in order to protect the system.
Turn the engine switch off and then start
the engine or turn the engine switch to
ON.
