following procedure:

1

Fully tighten the spare tire clamp bolt by 

turning the jack handle clockwise until 

two clicks are heard and the jack handle 

skips.

2

Turn the jack handle counterclockwise 

to lower the spare tire.

If the spare tire still cannot be lowered, 

attempt to fully tighten the spare tire clamp 

bolt again by turning the jack handle clock-

wise. Then turn it counterclockwise at least 

2 turns to lower the spare tire.

If the spare tire still cannot be lowered, the 

wire cable may be severed. Have the vehi-

cle inspected by any authorized Lexus 

retailer or Lexus authorized repairer, or any 

reliable repairer.

WARNING

Replacing a flat tire

Observe the following precautions.

Failure to do so may result in serious 

injury:

• Do not try to remove the wheel orna-

ment by hand. Take due care in han-

dling the ornament to avoid 

unexpected personal injury.

• Do not touch the disc wheels or the 

area around the brakes immediately 

after the vehicle has been driven.

After the vehicle has been driven the 

disc wheels and the area around the 

brakes will be extremely hot. Touching 

these areas with hands, feet or other 

body parts while changing a tire, etc. 

may result in burns.

Failure to follow these precautions 

could cause the wheel nuts to loosen 

and the tire to fall off, resulting in death 

or serious injury.

• Never use oil or grease on the wheel 

bolts or wheel nuts.

Oil and grease may cause the wheel 

nuts to be excessively tightened, lead-

ing to bolt or disc wheel damage. In 

addition, the oil or grease can cause 

the wheel nuts to loosen and the wheel 

may fall off, causing an accident and 

resulting in death or serious injury. 

Remove any oil or grease from the 

wheel bolts or wheel nuts.

• Have the wheel nuts tightened with a 

torque wrench to 103 N•m (10.5 

kgf•m, 76 ft•lbf) as soon as possible 

after changing wheels.

• When installing a tire, only use wheel 

nuts that have been specifically 

designed for that wheel.

• If there are any cracks or deformations 

in the bolt screws, nut threads or bolt 

holes of the wheel, have the vehicle 

inspected by any authorized Lexus 

retailer or Lexus authorized repairer, 

or any reliable repairer.

• Do not attach a heavily damaged 

wheel ornament, as it may fly off the 

wheel while the vehicle is moving.

Observe the following precautions. 

(Type C)

Failure to do so may result in serious 

injury:

7-2. Steps to take in an emergency

1

Remove any dirt or foreign matter 
from the wheel contact surface.

If foreign matter is on the wheel contact 

surface, the wheel nuts may loosen while 

the vehicle is in motion, causing the tire to 

come off.

2

Install the spare tire and loosely 
tighten each wheel nut by hand by 
approximately the same amount.

Vehicles with a compact spare tire

Tapered portion

Tighten the wheel nuts until the tapered 
portion comes into loose contact with the 
disc wheel seat.

Vehicles with a full-size spare tire

Turn the wheel nuts until the washers come 
into contact with the disc wheel.

WARNING

• Do not try to remove the wheel orna-

ment by hand. Take due care in han-

dling the ornament to avoid 

unexpected personal injury.

• Lower the spare tire completely to the 

ground before removing it from under 

the vehicle.

Replacing a flat tire for vehicles with 

power back door

In cases such as when replacing tires, 

make sure to canceling the power back 

door system (

P.592). Failure to do so 

may cause the back door to operate 

unintentionally if the power back door 

switch is accidentally touched, resulting 

in hands and fingers being caught and 

injured.

The compact spare tire (vehicles with a 

compact spare tire)

The compact spare tire is identified by the 

label “TEMPORARY USE ONLY” on 

the tire sidewall. Use the compact spare 

tire temporarily, and only in an emer-

gency.

Make sure to check the tire inflation pres-

sure of the compact spare tire. (

P.589)

When using the compact spare tire 

(vehicles with a compact spare tire)

As the compact spare tire is not equipped 

with a tire pressure warning valve and trans-

mitter, low inflation pressure of the spare 

tire will not be indicated by the tire pressure 

warning system. Also, if you replace the 

compact spare tire after the tire pressure 

warning light comes on, the light remains 

on.

When the compact spare tire is 

equipped (vehicles with a compact 

spare tire)

When driving with the compact spare tire 

installed, the vehicle height will be different 

than when driving with standard tires.

If you have a flat front tire on a road cov-

ered with snow or ice (vehicles with a 

compact spare tire)

Install the compact spare tire on one of the 

rear wheels of the vehicle. Perform the fol-

lowing steps and fit tire chains to the front 

tires:

1

Replace a rear tire with the compact 

spare tire.

2

Replace the flat front tire with the tire 

removed from the rear of the vehicle.

3

Fit tire chains to the front tires.

WARNING

When the compact spare tire is 

attached (vehicles with a compact 

spare tire)

The vehicle speed may not be correctly 

detected, and the following systems may 

not operate correctly:

• ABS & Brake assist

• VSC

• TRC

• Trailer Sway Control

• EPS

• VDIM (if equipped)

• Adaptive Variable Suspension System 

(if equipped)

• Cruise control (if equipped)

• Dynamic radar cruise control with 

full-speed range (if equipped)

• PCS (Pre-Collision System)

• LTA (Lane Tracing Assist) (if equipped)

• RSA (Road Sign Assist) (if equipped)

• Automatic High Beam (if equipped)

• AHS (Adaptive High-beam System) (if 

equipped)

• Tire pressure warning system

• Lexus parking assist-sensor (if 

equipped)

• PKSB (Parking Support Brake) (if 

equipped)

• Lexus parking assist monitor (if 

equipped)

• Panoramic view monitor (if equipped)

• BSM (Blind Spot Monitor) (if 

equipped)

• Navigation system (if equipped)

Also, not only can the following system 

not be utilized fully, but it may even nega-

tively affect the drive-train components:

• AWD system (AWD models)

Speed limit when using the compact 

spare tire (vehicles with a compact 

spare tire)

Do not drive at speeds in excess of 80 

km/h (50 mph) when a compact spare 

tire is installed on the vehicle.

The compact spare tire is not designed 

for driving at high speeds. Failure to 

observe this precaution may lead to an 

accident causing death or serious injury.

After using the tools and jack

Before driving, make sure all the tools 

and jack are securely in place in their 

storage location to reduce the possibility 

of personal injury during a collision or 

sudden braking.

NOTICE

Be careful when driving over bumps 

with the compact spare tire installed 

on the vehicle (vehicles with a com-

pact spare tire)

The vehicle becomes lower when driving 

with the compact spare tire compared to 

when driving with standard tires. Be 

careful when driving over uneven road 

surfaces.

Driving with tire chains and the com-

pact spare tire (vehicles with a com-

pact spare tire)

Do not fit tire chains to the compact 

spare tire. Tire chains may damage the 

vehicle body and adversely affect driving 

performance.

7-2. Steps to take in an emergency

NOTICE

When replacing the tires

When removing or fitting the wheels, 

tires or the tire pressure warning valve 

and transmitter, contact any authorized 

Lexus retailer or Lexus authorized 

repairer, or any reliable repairer as the 

tire pressure warning valve and transmit-

ter may be damaged if not handled cor-

rectly.

When stowing the flat tire (Type C)

Ensure that there is no object caught 

between the tire and the vehicle 

underbody.

Securely tighten the spare tire clamp 

bolt to hold the spare wheel carrier by 

the hook.

Stow the flat tire in the spare tire loca-

tion. Failure to do so may cause dam-

age to the spare tire carrier. Proper 

storage reduces the possibility of injury 

in a collision or during sudden braking.

Have the flat tire repaired and the 

spare tire replaced with it as soon as 

possible.

Proper storage of the spare tire (Type 

C)

If the hoist assembly is slanted when 

stowing a tire, the hoist assembly may 

become stuck in the wheel opening 

and the tire may not be raised properly, 

causing damage to the wheel or the 

wire cable.

Do not attempt to turn the spare tire 

clamp bolt without a tire on the hoist 

assembly, as doing so may cause the 

wire cable to slip off of the shaft inside 

the unit and the wire cable may not be 

able to be raised or lowered. If the 

spare tire clamp bolt has been turned 

without a tire on the hoist assembly 

and the wire cable cannot be raised or 

lowered, contact any authorized Lexus 

retailer or Lexus authorized repairer, 

or any reliable repairer.
