. WARNING:
This vehicle may have
more than one battery. Removing the
battery cables from only one battery does
not disconnect your vehicle electrical
system. Make sure you disconnect the
battery cables from all batteries when
disconnecting power. Failure to do so may
cause serious personal injury or property
damage.
The battery is in the engine compartment.
See
Under Hood Overview (page 334).
Your vehicle has a maintenance-free battery.
It does not require additional water during
service.
For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the battery
terminals. If any corrosion is present on the

If you disconnect or replace the battery and
your vehicle has an automatic transmission,
it must relearn its adaptive strategy. Because
of this, the transmission may shift firmly when
first driven. This is normal operation while
the transmission fully updates its operation
to optimum shift feel.
Remove and Reinstall the Battery
To disconnect or remove the battery, do the
following:
1. Apply the parking brake and switch the
ignition off.
2. Switch all electrical equipment off, for example lights and radio.
3. Wait a minimum of two minutes before disconnecting the battery.
Note: The engine management system has
a power hold function and remains powered

LOCATING THE TIRE LABEL
You will find a Tire Label containing tire
inflation pressure by tire size and other
important information located on the
B-Pillar or the edge of the driver's door.
See Locating the Safety Compliance
Certification Labels (page 290).
DEPARTMENT OF
TRANSPORTATION UNIFORM TIRE
QUALITY GRADES Tire Quality Grades apply to new
pneumatic passenger car tires. The
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Treadwear 200
Traction AA Temperature A.
These Tire Quality Grades are
determined by standards that the United
States Department of Transportation has
set.
Tire Quality Grades apply to new
pneumatic passenger car tires. They do
not apply to deep tread, winter-type
snow tires, space-saver or temporary
use spare tires, light truck or LT type
tires, tires with nominal rim diameters of
10 to 12 inches or limited production tires
as defined in Title 49 Code of Federal
Regulations Part 575.104 (c)(2).
U.S. Department of Transportation Tire
quality grades: The U.S. Department of
Transportation requires us to give you
the following information about tire
grades exactly as the government has
written it. Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear 1½ times as well on the
government course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
Traction AA A B C
WARNING:
The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning or peak
traction characteristics.
363
2021 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202011, First-Printing Wheel and Tire InformationE142542
The traction grades, from highest to
lowest are AA, A, B, and C. The grades
represent the tire
’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
Temperature A B C WARNING: The temperature
grade for this tire is established for a
tire that is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire failure.
The temperature grades are A (the
highest), B and C, representing the tire ’s
resistance to the generation of heat and
its ability to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance which all
passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 139. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law.
INFORMATION ON THE TIRE
SIDEWALL
Both United States and Canada Federal
regulations require tire manufacturers
to place standardized information on the
sidewall of all tires. This information
identifies and describes the fundamental
characteristics of the tire and also
provides a U.S. DOT Tire Identification
Number for safety standard certification
and in case of a recall.
Information on P Type Tires
P215/65R15 95H is an example of a tire
size, load index and speed rating. The
definitions of these items are listed
below. (Note that the tire size, load index
and speed rating for your vehicle may
be different from this example.)

Maximum Inflation Pressure:
Indicates the tire manufacturers'
maximum permissible pressure or the
pressure at which the maximum load
can be carried by the tire. This pressure
is normally higher than the vehicle
manufacturer's recommended cold
inflation pressure which can be found
on the Safety Compliance Certification
Label (affixed to either the door hinge
pillar, door-latch post, or the door edge
that meets the door-latch post, next to the driver's seating position), or Tire
Label which is located on the B-Pillar or
the edge of the driver’
s door. The cold
inflation pressure should never be set
lower than the recommended pressure
on the vehicle label.
The tire suppliers may have additional
markings, notes or warnings such as
standard load or radial tubeless.
Additional Information Contained on
the Tire Sidewall for LT Type Tires
Note: Tire Quality Grades do not apply
to this type of tire. LT type tires have some additional
information beyond those of P type tires;
these differences are described below.
A. LT: Indicates a tire, designated by the
