21. Inflate the compact spare tire to a pressure of 43.5 psi (3 bar).

NOTE:
If spare tire is overinflated, be sure to lower the
psi in the tire to the recommended amount by
using the deflation button on the air compressor.
22. Operate the wheel wrench on the jack to lower the vehicle.
23. Remove the jack. 24. Use the wheel wrench to fully tighten the
bolts, passing alternately from one bolt to the
diagonally opposite one.
To obtain a more accurate reading, it is advisable
to check the pressure of the compact spare tire
on the pressure gauge with the compressor off.

NOTE:
Do not stow the deflated tire in the compact spare
tire location.
The compressor was designed for inflating the
compact spare tire. Do not use it for inflating
mattresses, rafts, etc.

NOTE:
Spare tires are intended for temporary use only.
Have the full-sized tire repaired or replaced, as
soon as possible.
TIRE SERVICE KIT —
IF EQUIPPED
DESCRIPTION
If a tire is punctured, you can make an emergency
repair using the Tire Service Kit located in the rear
storage area under the load platform.
1. Stop the vehicle in a position where you can repair the tire safely. You should be as far as
possible from the side of the road, and in a
position that is not dangerous for oncoming
traffic. Turn on the Hazard Warning Flashers,
remove the safety triangle from the luggage
compartment, and place it at a suitable
distance from the vehicle to make other
drivers aware of your presence.
2. Verify that the valve stem (on the wheel with the deflated tire) is in a position that is near
to the ground. This will allow the tire repair kit
hoses to reach the valve stem and keep the
tire service kit flat on the ground.
3. Place the gear selector in PARK (P).
4. Apply the electric park brake and turn the engine OFF.

the vehicle has been lowered. Failure to follow
this warning may result in serious injury.
WARNING!
A loose tire or jack thrown forward in a colli -
sion or hard stop could endanger the occu -
pants of the vehicle. Always stow the jack
parts and the spare tire in the places provided.

Tire Terminology And Definitions
Tire Loading And Tire Pressure

NOTE:
The proper cold tire inflation pressure is listed on
the driver’s side B-pillar or the rear edge of the
driver's side door.
Check the inflation pressure of each tire,
including the spare tire (if equipped), at least
monthly and inflate to the recommended
pressure for your vehicle.Example Tire Placard Location (Door)Example Tire Placard Location (B-pillar)
TermDefinition
B-pillarThe vehicle B-pillar is the structural member of the body located behind the front door.
Cold Tire Inflation Pressure Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been
driven for at least three hours, or driven less than 1 mile (1.6 km) after sitting for a
minimum of three hours. Inflation pressure is measured in units of PSI (pounds per square
inch) or kPa (kilopascals).
Maximum Inflation Pressure The maximum inflation pressure is the maximum permissible cold tire inflation pressure
for this tire. The maximum inflation pressure is molded into the sidewall.
Recommended Cold Tire Inflation Pressure Vehicle manufacturer's recommended cold tire inflation pressure as shown on the tire
placard.
Tire Placard A label permanently attached to the vehicle describing the vehicle’s loading capacity, the
original equipment tire sizes and the recommended cold tire inflation pressures.

Tire And Loading Information PlacardTire And Loading Information Placard
This placard tells you important information
about the:
1. Number of people that can be carried in the vehicle.
2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear, and spare tires.
Loading
The vehicle maximum load on the tire must not
exceed the load carrying capacity of the tire on
your vehicle. You will not exceed the tire's load
carrying capacity if you adhere to the loading
conditions, tire size, and cold tire inflation
pressures specified on the Tire and Loading
Information placard

Ú
page 126.

NOTE:
Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front
and rear axles must not be exceeded. For further
information on GAWRs, vehicle loading, and
trailer towing

Ú
page 126. To determine the maximum loading conditions of
your vehicle, locate the statement “The combined
weight of occupants and cargo should never
exceed XXX kg or XXX lbs” on the Tire and Loading
Information placard. The combined weight of
occupants, cargo/luggage and trailer tongue
weight (if applicable) should never exceed the
weight referenced here.
Steps For Determining Correct Load
Limit—
(1) Locate the statement “The
combined 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 that will be
riding in your vehicle.
(3) Subtract the combined weight of the
driver and passengers from XXX kg or
XXX lbs.
(4) The resulting figure equals the
available amount of cargo and luggage
load capacity. For example, if “XXX”
amount equals 1400 lbs. and there will
be five 150 lb passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400-750 (5x150) = 650 lbs.).
(5) Determine the combined weight of
luggage and cargo being loaded on the
vehicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer,
load from your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the
available cargo and luggage load
capacity of your vehicle.
Metric Example For Load Limit

For example, if “XXX” amount equals 635 kg and
there will be five 68 kg passengers in your vehicle,
the amount of available cargo and luggage load
capacity is 295 kg (635-340 (5x68) = 295 kg) as
shown in step 4.
NOTE:

If your vehicle will be towing a trailer, load from
your trailer will be transferred to your vehicle.
The following table shows examples on how to
calculate total load, cargo/luggage, and
towing capacities of your vehicle with varying
seating configurations and number and size of
occupants. This table is for illustration
purposes only and may not be accurate for the
seating and load carry capacity of your vehicle.
For the following example, the combined
weight of occupants and cargo should never
exceed 865 lbs (392 kg).

Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits. Where
speed limits or conditions are such that the
vehicle can be driven at high speeds, maintaining
correct tire inflation pressure is very important.
Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle
operation. Refer to an authorized tire dealer or
original equipment vehicle dealer for
recommended safe operating speeds, loading
and cold tire inflation pressures.Recommended Cold Tire Inflation Pressures
For vehicle speeds below 100 mph (160 km/h),
recommended cold tire inflation pressures are
listed on the Tire And Loading Information
Placard located on driver’s side B-pillar or the rear
edge of the driver's side door. When driving at speeds 100 mph (160 km/h)
and above, increased tire pressures and reduced
vehicle loading are required for high-speed
vehicle operation.
For driving speeds above 100 mph (160 km/h)
recommended cold tire inflation pressures are
listed below under “High Speed Tire Inflation
Pressure”. Vehicle loading condition must not
exceed 688 lbs. (312 kg) (driver + three
passengers + 88 lbs. (40kg) luggage).
2.0L Engine

NOTE:
Using tires of a different size, type, brand or design on the front and rear may adversely affect vehicle drive-ability. We recommend using only tires approved
by the manufacturer. The manufacturer cannot determine if unapproved tires are suitable for use and therefore cannot guarantee vehicle safety in those
conditions.
WARNING!

High speed driving with your vehicle under max -
imum load is dangerous. The added strain on
your tires could cause them to fail. You could
have a serious collision. Do not drive a vehicle
loaded to the maximum capacity at continuous
speeds above 75 mph (120 km/h).

WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added strain
on your tires could cause them to fail. You

Tire Repair
If your tire becomes damaged, it may be repaired
if it meets the following criteria:
The tire has not been driven on when flat.
The damage is only on the tread section of your
tire (sidewall damage is not repairable).
The puncture is no greater than a ¼ of an inch
(6 mm).
Consult an authorized tire dealer for tire repairs
and additional information.

Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical
size and service description (Load Index and
Speed Symbol). Replace the tire pressure sensor
as well as it is not designed to be reused.

Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after a rapid loss of inflation pressure. This rapid loss of
inflation is referred to as the Run Flat mode. A
Run Flat mode occurs when the tire inflation pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has
limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable. When a run flat tire is changed after
driving with underinflated tire condition, please
replace the TPMS sensor as it is not designed to
be reused when driven under run flat mode 14 psi
(96 kPa) condition.

NOTE:
TPMS Sensor must be replaced after driving the
vehicle on a flat tire condition.
It is not recommended driving a vehicle loaded at
full capacity or to tow a trailer while a tire is in the
run flat mode.
