Tongue load or king pin weight
●A recommended tongue load or king pin weight varies in accordance with
the types of trailers or towing as described below.
● In order to ensure the recommended values shown below, the trailer must
be loaded by referring to the following instructions.
1. Conventional Towing The trailer cargo load should be distributed so that the tongue load is 9 to
11% of the gross trailer weight, not exceeding the following.
(Tongue load/Gross trailer weight x 100 = 9 to 11%)
If the gross trailer weight is over 2000 lbs. (907 kg), it is necessary to use a
sway control device with sufficient capacity.
If the gross trailer weight is over 5000 lbs.(2268 kg), it is necessary to use
a weight distributing hitch with sufficient capacity.
If using a weight distributing hitch when towing, keep your vehicle level
with the ground.
2. Fifth wheel Towing The king pin weight is 15 to 25% of the Gross Trailer weight.
(King pin weight/Gross trailer weight x 100 = 15 to 25%)

As the audio system is compatible with multi-sessions, it is possible to play
discs that contain MP3 and WMA files. However, only the first session can
be played.
● ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track

When a disc containing MP3 or WMA files is inserted, all files on the disc
are first checked. Once the file check is finished, the first MP3 or WMA\

Maintenance and care
■
Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
● More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
● A new engine consumes more oil.
● When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level accu-
rately.
■ After changing the engine oil (U.S.A. only)
The oil change system should be reset. Perform the following procedures:
Turn the engine switch off with the trip meter A reading shown.
While pressing the trip meter reset button ( P. 188, 190), turn the
engine switch on.
Without multi-information display Continue to press and hold the button until the trip meter displays
000000.
With multi-information display
Continue to press and hold the button until “MAINT REQD RESET
MODE COMPLETE” appears on the multi-information display.
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 your Toyota dealer, service station or auto parts store for
information concerning recycling or disposal.
● Do not leave used engine oil within the reach of children.

turn the engine switch to the ACC
position, shift the shift lever to N
and put the front wheel drive con-
trol switch in 2WD.
Using a flat bed truck

NOTICE
■To prevent damaging the vehicle
●Do not tow the vehicle with the key removed or in the LOCK position.
The steering lock mechanism is not strong enough to hold the front wheel
straight.
● When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed.
