Installation of a RF-transmitter system
As the installation of an RF-transmitter system in your vehicle could affect
electronic systems such as the multi-port fuel injection system/sequential
multi-port fuel injection system, anti-lock brake system, SRS airbag system
or seat belt pretensioner system, be sure to check with any authorized
Toyota dealer or repairer, or another duly qualified and equipped
professional for precautionary measures or special instructions regarding
installation.
Further information regarding frequency bands, power levels, antenna posi-
tions and installation provisions for the installation of RF-transmitters, is
available on request at any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in your Toyota contain
explosive chemicals. If the vehicle is scrapped with the airbags and seat belt
pretensioners left as they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat belt pretensioner
removed and disposed of by a qualified service shop or by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional, before you scrap your vehicle.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
Pre-winter preparations
Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
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 same size and brand, and that chains
match the size of the tires.
Before driving the vehicle
Perform the following according to the driving conditions.
Do not try to forcibly open a window, scrape an outside rear
view mirror surface or move a wiper or outside rear view mir-
ror that is frozen. Pour warm water over the frozen area to
melt the ice. Wipe away the water immediately to prevent it
from freezing.
To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
Remove any ice that has accumulated on the vehicle chassis.
Periodically check for and remove any excess ice or snow
that may have accumulated in the wheel well or on the
brakes.

4-2. Maintenance
Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular
maintenance is essential. Toyota recommends the following mainte-
nance.
Scheduled maintenance
Scheduled maintenance be performed at specified intervals
according to the maintenance schedule.
For full details of your maintenance schedule, read the “Toyota
Service Booklet” or “Toyota Warranty Booklet”.
Do-it-yourself maintenance
What about do-it-yourself maintenance?
Many maintenance items are easy to do yourself if you have a little
mechanical ability and a few basic automotive tools.
Note, however, that some maintenance tasks require special tools
and skills. These are best performed by qualified technicians. Even if
you’re an experienced do-it-yourself mechanic, we recommend that
repairs and maintenance be conducted by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional. Any authorized Toyota dealer or repairer will keep a record of
maintenance, which could be useful should you ever require Warranty
Service. Should you choose to select a qualified and equipped profes-
sional other than an authorized Toyota repairer to service or maintain
your vehicle, we recommend that you request that a record of mainte-
nance be kept.

Where to go for maintenance service?
In order to maintain your vehicle in the highest possible condition, Toyota
recommends that maintenance service operations as well as other inspec-
tions and repairs be carried out by authorized Toyota dealers or repairers or
other duly qualified and equipped professionals. For repairs and services
covered by your warranty, please visit an authorized Toyota dealer or
repairer, who will use genuine Toyota parts in repairing any difficulties you
may encounter. There can also be advantages in utilizing authorized Toyota
dealers or repairers for non-warranty repairs and services, as members of
the Toyota network will be able to expertly assist you with any difficulties you
may encounter.
Any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional service department will perform all of the scheduled
maintenance on your vehicle-reliably and economically due to their experi-
ence with Toyota vehicles.

Does your vehicle need repair?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon mon-
oxide leak. Drive with the windows open and have the exhaust system
checked immediately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
Vehicle pulls to one side when driving straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional, as
soon as possible. Your vehicle may need adjustment or repair.
CAUTION
If your vehicle is not properly maintained
It could result in serious damage to the vehicle and possible serious injury or
death.
Warning in handling of the battery
Battery posts, terminals and related accessories contain lead and lead com-
pounds which are known to cause brain damage. Wash your hands after
handling. (P. 342)

Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the follow-
ing situations, oil consumption may increase, and engine oil may need to be
refilled in between oil maintenance intervals.
When the engine is new, for example directly after purchasing the vehicle
or after replacing the engine
If low quality oil or oil of an inappropriate viscosity is used
When driving at high engine speeds or with a heavy load, or when driving
while accelerating or decelerating frequently
When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
CAUTION
Used engine oil
Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation or skin cancer, so care should
be taken to avoid prolonged and repeated contact. To remove used engine
oil from your skin, wash thoroughly with soap and water.
Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewers or onto the
ground. Call any authorized Toyota dealer or repairer, or another duly
