11. Check the air pressure of the
replaced tire.
Adjust the air pressure to the specification
designated in Part 8. If the pressure is
lower, drive slowly to the nearest service station and fill to the correct pressure.
Do not forget to reinstall the tire inflation valve cap as dirt and moisture could get into the valve core and possibly cause air
leakage. If the cap is missing, have a new
one put on as soon as possible.
12. Restow all the tools, jack and flat
tire securely.
Xtra-cab models-After fixing the jack, put
the tool bag over the jack and fasten the tool bag with rubber bands shown in the il-

Towing in this manner may be done only
on hard-surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, drive train, steering and brakes must all be in good condition.
CAUTION!
Use extreme caution when towing
vehicles. Avoid sudden starts or
erratic driving maneuvers which
would place excessive stress on the
emergency towing eyelet and
towing cable or chain. The eyelet
and towing cable or chain may break and cause serious injury or damage.
NOTICE
Use only a cable or chain specific- ally intended for use in towing
vehicles. Securely fasten the cableor chain to the towing eyelet provided.
Before towing, release the parking brake
and put the transmission in neutral
(manual) or Nº (automatic) and the trans-
fer in H2º (four-wheel drive models). The
key must be in ACCº (engine off) or ONº

CAUTION!
If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual.
If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-vice.
If towing service is not available in an
emergency, your vehicle may be tem-
porarily towed by a cable or chain se-
cured to the emergency towing hook
under the front of the vehicle. Use ex-
treme caution when towing the ve-hicle.
A driver must be in the vehicle to steer it and operate the brakes.

206When the truck is used to carry a slide-in
camper, the total cargo load of the truck
consists of the manufacturer's camper
weight figure,
the weight of installed addi-
tional camper equipment not included in
the manufacturer's camper weight figure,
the weight of camper cargo and the
weight of passengers in the camper.
The total cargo load should not exceed
the truck's cargo weight rating and the
camper 's center of gravity should fall with-
in the truck's recommended center of
gravity zone when installed.
CAUTION
Be carefulÐoverloading can cause
dangerous braking and handling
problems, and can damage your ve-
hicle and its tires.!
Secure loose items to prevent weight
shifts that could affect the balance of your
vehicle. When the truck camper is loaded, drive to a scale and weigh on the front and
on the rear wheels separately to deter-
mine axle loads. Individual axle loads
should not exceed either of the Gross
Axle Weight Rati ngs (GAWR). The total of
the axle loads should not exceed the
Gross Vehicle Weight Rating (GVWR).
The GARW and GVWR are indicated on
the Certification Label. See Your T oyota's
identificationº in Part 2 for the Certification
Label location.GAWR
