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.

vehicle inspected by your Lexus dealer.

■

If there is an overload in a circuit

The fuses are designed to blow, protecting

the wiring harness from damage.

■

When replacing light bulbs

Lexus recommends that you use genuine

Lexus products designed for this vehicle.

Because certain bulbs are connected to cir-

cuits designed to prevent overload, non-

genuine parts or parts not designed for this

vehicle may be unusable.

To prevent system breakdowns and

vehicle fire

Observe the following precautions.

Failure to do so may cause damage to

the vehicle, and possibly a fire or injury.

●

Never use a fuse of a higher amperage

rating than that indicated, or use any

other object in place of a fuse.

●

Always use a genuine Lexus fuse or

equivalent.

Never replace a fuse with a wire, even

as a temporary fix.

●

Do not modify the fuses or fuse boxes.

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.

If your vehicle needs to be
towed

If towing is necessary, 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.

Situations when it is necessary to
contact dealers before towing

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.

492

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.

Securely attach cables or chains to
the towing hook.

Take care not to damage the vehicle body.

Enter the vehicle being towed and
start the engine.

If the engine does not start, turn the engine

switch to ON.

Put the four-wheel drive control
switch in “H4”. (The center differ-
ential is unlocked.)

Vehicles with AHC: Change the
vehicle height to N (standard)
mode and end the vehicle height
operation. (

P.350)

Shift the shift lever to N and release
the parking brake.

Turn automatic mode off. (

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

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. (



P.350)

●

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.
