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 tempo-
rarily 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 vehicle.
NOTICE
Only use specified towing hook;
otherwise your vehicle may be dam-
aged.
A driver must be in the vehicle to steer
it and operate the brakes.
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 the
vehicle. Avoid sudden starts or errat-
ic driving maneuvers which would
place excessive stress on the emer-
gency towing hook and towing cable
or chain. The hook and towing cable
or chain may break and cause serious
injury or damage.
NOTICE
Use only a cable or chain specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing hook provided.
Before towing, release the parking brake,
put the transmission in neutral (manual) or
N" (automatic) and set the transfer in
H2" mode. The key must be in ACC"
(engine off) or ON" (engine running).
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.

ic, the Toyota service manuals are recom-
mended. Please be aware that do−it−your-
self maintenance can affect your warranty
coverage. See Owner ’s Warranty Informa-
tion Booklet" or Owner ’s Manual Supple-
ment" for the details.

Gross axle weight ratingFront GAWR Rear GAWR
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 de-
termine axle loads. Individual axle loads
should not exceed either of the Gross
Axle Weight Ratings (GAWR). The total of
the axle loads should not exceed the
Gross Vehicle Weight Rating (GVWR).
These ratings are given on the vehicle
Certification Label which is located on the
door latch post on the left side of the
vehicle. See Your Toyota’s identification"
in Section 2 for the Certification Label
location. If weight ratings are exceeded,
move or remove items to bring all weights
below the ratings.
