Cargo and luggage
Cargo capacity depends on the total weight of the occupants. 
(Cargo capacity) = (Total load capacity) — (Total weight of occ upants)
Steps for Determini ng Correct Load Limit  
(1) Locate  the  statement  “The  co mbined  weight  of  occupants  and
cargo  should  never  exceed  XXX  kg  or  XXX  lbs.”  on  your  vehicle’s
placard. 
(2) Determine  the  combined  weight  of  the  driver  and  passengers  t hat
will be riding in your vehicle. 
(3) Subtract  the  combined  weight  of  the  driver  and  passengers  fr om
XXX kg or XXX lbs.
(4) The  resulting  figure  equals  the  available  amount  of  cargo  an d  lug-
gage load capacity. 
For example, if the “XXX” amount equals 1400 lbs. and there wil l be
five  150  lb  passengers  in  your  vehicle,  the  amount  of  available
cargo and luggage load capacity is 650 lbs. (1400   750 (5150) =
650 lbs.) 
(5) Determine the combined weight of luggage and cargo being loa ded
on  the  vehicle.  That  weight  may  n ot  safely  exceed the  available
cargo and luggage load capac ity calculated in Step 4. 
(6) If your vehicle will be towing a trailer, load from your tra iler  will  be
transferred  to  your  vehicle.  Consult  this  manual  to  determine  h ow
this reduces the available cargo and luggage load capacity of y our
vehicle. ( P. 242)
Toyota  does  not  recommend  towing  a  trailer  with  your  vehicle.  Y our
vehicle is not desig ned for trailer towing.
Take  notice  of  the  following  information  about  storage  precau-
tions, cargo capacity and load.

Cargo capacity
Total  load  capacity  (vehicle
capacity weight) (P. 664)
When  2  people  with  the  combined  weight  of  A  lb.  (kg)  are  riding  in
your vehicle, which has a total load capacity (vehicle capacity weight)
of B lb. (kg), the available amount of cargo and luggage load c apacity
will be C lb. (kg) as follows: 
B
*2 lb. (kg)  A*1 lb. (kg) = C*3 lb. (kg)
*1: A = Weight of people
*2: B = Total load capacity
*3: C = Available cargo and luggage load
In  this  condition,  if  3  more  passengers  with  the  combined  weigh t  of
D lb. (kg) get on, the availabl e cargo and luggage load will be  reduced
E lb. (kg) as follows:
C lb. (kg)   D*4 lb. (kg) = E*5 lb. (kg)
*4: D = Additional  weight of people
*5: E = Available cargo and luggage load
As  shown  in  the  example  above,  if  the  number  of  occupants
increases, the cargo and luggage load will be reduced  by an  amo unt
that  equals  the  increased  weight  due  to  the  additional  occupant s.  In
other  words,  if  an  increase  in  the  number  of  occupants  causes  a n
excess of the total load capacity  (combined weight of  occupants plus
cargo and luggage load), you must reduce the cargo and luggage  on
your vehicle.

WARNING
■Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compart-
ment:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed pr operly,
may block the driver’s vision, or may result in items hitting t he driver or
passengers, possibly causing an accident.
●Stow cargo and luggage in the luggage compartment whenever poss i-
ble.
●Do  not  stack  cargo  and  luggage  in  the  luggage  compartment  highe r
than the seatbacks.
●When  you  fold  down  the  rear  seats,  long  items  should  not  be  pla ced
directly behind the front seats.
●Never  allow  anyone  to  ride  in  the  luggage  compartment.  It  is  no t
designed for passengers. They should ride in their seats with t heir seat
belts properly fastened.
●Do not place cargo or luggage in  or on the following locations.
• At the feet of the driver
• On the front passenger or rea r seats (when stacking items)
• On the luggage cover (if equipped)
• On the instrument panel
• On the dashboard
●Secure all items in the occupant compartment.
■Capacity and distribution
●Do  not  exceed  the  maximum  axle  weight  rating  or  the  total  vehic le
weight rating. 
●Even  if  the  total  load  of  occupant’s  weight  and  the  cargo  load  is  less
than  the  total  load  capacity,  d o  not  apply  the  load  unevenly.  I mproper
loading  may  cause  deterioration  of  steering  or  braking  control  which
may cause death or  serious injury.

WARNING
■When the TRAC/VSC systems are turned off
Be  especially  careful  and  drive  at  a  speed  appropriate  to  the  r oad  condi-
tions. As  these  are  the  systems  to  help  ensure  vehicle  stabilit y  and  driving
force, do not turn the TRAC/VSC systems off unless necessary.
■ Replacing tires
Make  sure  that  all  tires  are  of  the  specified  size,  brand,  trea d  pattern  and
total  load  capacity.  In  addition,  make  sure  that  the  tires  are  inflated  to  the
recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if di fferent tires
are installed on the vehicle.
Contact  your  Toyota  dealer  for  further  information  when  replaci ng  tires  or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspensio n will affect
the driving assist systems, and may cause a system to malfuncti on.

Maintenance and care
■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Si nce summer tires do not have th e same
traction  performance  as  snow  tires,  summer  tires  are  inadequate  for
driving  on  snow-covered  or  icy  ro ads.  For  driving  on  snow-covered
roads or icy roads, the use of snow tires is recommended. When  install-
ing snow tires, be sure to replace all four tires.
●All season tires
All  season  tires  are  designed  to  provide  better  traction  in  sno w  and  to
be  adequate  for  driving  in  most  winter  conditions  as  well  as  fo r  use
year-round.  All  season  tires,  however,  do  not  have  adequate  tra ction
performance compared with snow tires in heavy or loose snow. Al so, all
season  tires  fall  short  in  acceleration  and  handling  performanc e  com-
pared with summer tires in highway driving.
●Snow tires
For  driving  on  snow-covered  roads  or  icy  roads,  we  recommend  us ing
snow  tires.  If  you  need  snow  tires,  select  tires  of  the  same  si ze,  con-
struction  and  load  capacity  as  t he  originally  installed  tires. Since  your
vehicle  has  radial  tires  as  original  equipment,  make  sure  your  snow
tires  also  have  radial  construct ion.  Do  not  install  studded  tires  without
first  checking  local  regulations  for  possible  restrictions.  Sno w  tires
should be install ed on all wheels. ( P. 430)
■If the tread on snow tires wea rs down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
■Low profile tires (vehicl es with 215/45R17 tires)
Generally,  low  profile  tires  will  wear  more  rapidly  and  tire  gr ip  perfor-
mance  will  be  reduced  on  snowy  and /or  icy  roads  when  compared  to
standard tires.
Be  sure  to  use  snow  tires  or  tire  chains  on  snowy  and/or  icy  roads  and
drive carefully at a speed approp riate for road and weather conditions.

Maintenance and care
Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim wid th and
inset
*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that hav e been straightened
● Use  only  Toyota  wheel  nuts  and  wrenches  designed  for  use  with
your aluminum wheels.
● When  rotating,  repairing  or  changi ng  your  tires,  check  that  the
wheel nuts are still tight afte r driving 1000 miles (1600 km).
● Be  careful  not  to  damage  the  aluminum  wheels  when  using  tire
chains.
● Use only Toyota genuine balance we ights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
If  a  wheel  is  bent,  cracked  or  heavily  corroded,  it  should  be
replaced.  Otherwise,  the  tire  may  separate  from  the  wheel  or
cause a loss of handling control.

Engine oil selection
“Toyota  Genuine  Motor  Oil”  is  used  in  your  Toyota  vehicle.  Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to sat isfy
the following grade and viscosity.
Oil grade: API SN/RC multigrade engine oil
Recommended viscosity: SAE 0W-16
SAE  0W-16  is  the  best  choice
for  good  fuel  economy  and
good starting in cold weather.
If  SAE  0W-16  is  not  available,
SAE  0W-20  oil  may  be  used.
However,  it  must  be  replaced
with  SAE  0W-16  at  the  next  oil
change.
Oil viscosity (0W-16 is expl ained here as an example):
• The  0W  in  0W-16  indicates  the  characteristic  of  the  oil  which allows cold startability. Oils wi th a lower value before the W allow
for easier starting of the engine in cold weather.
• The  16  in  0W-16  indicates  the  vi scosity  characteristic  of  the oil
when the oil is at high temperature. An oil with a higher visco sity
(one  with  a  higher  value)  may  be  better  suited  if  the  vehicle  i s
operated at high speeds, or un der extreme load conditions.
