Check tire pressures more often if
subject to a wide range of outdoor
temperatures, as tire pressures vary
with temperature changes.
Tire pressures change by approxi-
mately 7 kPa per 7°C of air tempera-
ture change. Keep this in mind when
checking tire pressure inside a garage,
especially in the winter.
Example: If garage temperature =
20°C and the outside temperature =
0°C then the cold tire inflation pres-
sure should be increased by 21 kPa,
which equals 7 kPa for every 7°C for
this outside temperature condition.
Tire pressure may increase from 13 to
40 kPa during operation. DO NOT
reduce this normal pressure build up
or your tire pressure will be too low.Tire Pressures For High
Speed Operation
The manufacturer advocates driving
at safe speeds and within posted speed
limits. Where speed limits or condi-
tions 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 op-
eration. Refer to your authorized tire
dealer or original equipment vehicle
dealer for recommended safe operat-
ing speeds, loading and cold tire infla-
tion pressures.
WARNING!
High speed driving with your ve-
hicle under maximum load is dan-
gerous. 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 120 km/h.
Radial Ply Tires
WARNING!
Combining radial ply tires with
other types of tires on your vehicle
will cause your vehicle to handle
poorly. The instability could cause
a collision. Always use radial ply
tires in sets of four. Never combine
them with other types of tires.
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 dam-
age is not repairable).
The puncture is no greater than 6 mm.
Consult an authorized tire dealer for
tire repairs and additional informa-
tion.
226
It is not recommended driving a ve-
hicle loaded at full capacity or to tow
a trailer while a tire is in the run flat
mode.
See the tire pressure monitoring sec-
tion for more information.
Spare Tires (for
versions/markets, where
provided)
NOTE: For vehicles equipped
with TIREFIT instead of a spare
tire, please refer to “TIREFIT KIT”
in “In an emergency” for further
information.
CAUTION!
Because of the reduced ground
clearance, do not take your vehicle
through an automatic car wash
with a compact, full size or limited-
use temporary spare installed.
Damage to the vehicle may result.Spare Tire Matching Original
Equipped Tire And Wheel (for
versions/markets, where
provided)
Your vehicle may be equipped with a
spare tire and wheel equivalent in
look and function to the original
equipment tire and wheel found on
the front or rear axle of your vehicle.
This spare tire may be used in the tire
rotation for your vehicle. If your ve-
hicle has this option, refer to an au-
thorized tire dealer for the recom-
mended tire rotation pattern.
Compact Spare Tire (for
versions/markets, where
provided)The compact spare is for temporary
emergency use only. You can identify if
your vehicle is equipped with a com-
pact spare by looking at the spare tire
description on the Tire and Loading
Information Placard located on the
driver’s side door opening or on the
sidewall of the tire. Compact spare tire
descriptions begin with the letter “T”
or “S” preceding the size designation.
Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life,
the original equipment tire should be
repaired (or replaced) and reinstalled
on your vehicle at the first opportu-
nity.
Do not install a wheel cover or at-
tempt to mount a conventional tire on
the compact spare wheel, since the
wheel is designed specifically for the
compact spare tire. Do not install
more than one compact spare tire and
wheel on the vehicle at any given time.
WARNING!
Compact spares are for temporary
emergency use only. With these
spares, do not drive more than
80 km/h. Temporary use spares
have limited tread life. When the
tread is worn to the tread wear in-
dicators, the temporary use spare
tire needs to be replaced. Be sure to
follow the warnings, which apply to
your spare. Failure to do so could
result in spare tire failure and loss
of vehicle control.
228
It is recommended you contact your
authorized tire dealer or original
equipment dealer with any questions
you may have on tire specifications or
capability. Failure to use equivalent
replacement tires may adversely af-
fect the safety, handling, and ride of
your vehicle.
WARNING!
Do not use a tire, wheel size orrating other than that specified
for your vehicle. Some combina-
tions of unapproved tires and
wheels may change suspension
dimensions and performance
characteristics, resulting in
changes to steering, handling,
and braking of your vehicle. This
can cause unpredictable handling
and stress to steering and suspen-
sion components. You could lose
control and have a collision re-
sulting in serious injury or death.
Use only the tire and wheel sizes
with load ratings approved for
your vehicle.
(Continued)
WARNING!(Continued)
Never use a tire with a smallerload index or capacity, other than
what was originally equipped on
your vehicle. Using a tire with a
smaller load index could result in
tire overloading and failure. You
could lose control and have a col-
lision.
Failure to equip your vehicle with
tires having adequate speed capa-
bility can result in sudden tire fail-
ure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of
a different size may result in false
speedometer and odometer read-
ings.
TIRE CHAINS
(TRACTION DEVICES)
Use of traction devices require suffi-
cient tire-to-body clearance. Follow
these recommendations to guard
against damage.
Traction device must be of proper size for the tire, as recommended by
the traction device manufacturer.
Install on Rear Tires Only.
Due to limited clearance, on a 235/ 55R18 100V, use reduced size snow
chains or traction devices with a
maximum projection of 6 mm be-
yond the tire profile.
WARNING!
Using tires of different size and type
(M+S, Snow) between front and
rear axles can cause unpredictable
handling. You could lose control
and have a collision.
231
in its "loaded and ready for opera-
tion" condition. The recommended
way to measure GTW is to put your
fully loaded trailer on a vehicle scale.
The entire weight of the trailer must
be supported by the scale.
Gross Combination Weight Rating
(GCWR)
The GCWR is the total permissible
weight of your vehicle and trailer
when weighed in combination.
NOTE: The GCWR rating in-
cludes a 68 kg allowance for the
presence of a driver.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity
of the front and rear axles. Distribute
the load over the front and rear axles
evenly. Make sure that you do not
exceed either front or rear GAWR.
Refer to “Vehicle Loading/Vehicle
Certification Label” in “Starting and
Operating” for further information.WARNING!
It is important that you do not ex-
ceed the maximum front or rear
GAWR. A dangerous driving condi-
tion can result if either rating is
exceeded. You could lose control of
the vehicle and have a collision.
Tongue Weight (TW)
The tongue weight is the downward
force exerted on the hitch ball by the
trailer. In most cases, it should not be
less than 7% or more than 10% of the
trailer load. Tongue weight must not
exceed the lesser of either the hitch
certification rating, or the trailer
tongue chassis rating. It should never
be less than 4% of the trailer load, and
not less than 25 kg. You must consider
tongue load as part of the load on your
vehicle and its GAWR.
Frontal Area
The frontal area is the maximum
height multiplied by the maximum
width of the front of a trailer. Trailer Sway Control
The trailer sway control can be a me-
chanical telescoping link that can be
installed between the hitch receiver
and the trailer tongue that typically
provides adjustable friction associ-
ated with the telescoping motion to
dampen any unwanted trailer sway-
ing motions while traveling.
If equipped, the electronic Trailer
Sway Control (TSC) recognizes a
swaying trailer and automatically ap-
plies individual wheel brakes and/or
reduces engine power to attempt to
eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the
trailer tongue weight, just as if it were
luggage located at a hitch ball or some
other connecting point of the vehicle.
These kinds of hitches are the most
popular on the market today and they
are commonly used to tow small and
medium sized trailers.
241
load carrying capacity will not in-
crease the vehicle's GVWR and
GAWR limits.
Towing Requirements – Trailer
Brakes
–Do notinterconnect the hydraulic
brake system or vacuum system of
your vehicle with that of the trailer.
This could cause inadequate brak-
ing and possible personal injury.
– An electronically actuated trailer brake controller is required when
towing a trailer with electronically
actuated brakes. When towing a
trailer equipped with a hydraulic
surge actuated brake system, an
electronic brake controller is not
required.
– Trailer brakes are recommended for trailers over 454 kg and re-
quired for trailers in excess of
907 kg.CAUTION!
If the trailer weighs more than
454 kg loaded, it should have its
own brakes, and they should be of
adequate capacity. Failure to do
this could lead to accelerated brake
wear, higher brake pedal effort, and
longer stopping distances.
WARNING!
Do not connect trailer brakes toyour vehicle's hydraulic brake
lines. It can overload your brake
system and cause it to fail. You
might not have brakes when you
need them and could have an col-
lision.
Towing any trailer will increase your stopping distance. When
towing, you should allow for ad-
ditional space between your ve-
hicle and the vehicle in front of
you. Failure to do so could result
in a collision. Towing Requirements – Trailer
Lights And Wiring
Whenever you pull a trailer, regard-
less of the trailer size, stoplights and
turn signals on the trailer are required
for motoring safety.
The Trailer Tow Package may include
a 7-pin or a 13-pin wiring harness.
Use a factory approved trailer harness
and connector.
NOTE: Do not cut or splice wiring
into the vehicles wiring harness.
The electrical connections are all
complete to the vehicle but you must
mate the harness to a trailer connec-
tor.
