277).
CHECKING THE COOLANT WARNING:
Do not remove the
coolant reservoir cap when the vehicle
is on or the cooling system is hot. Wait
10 minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield. WARNING:
Do not add coolant
further than the MAX mark.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
Your vehicle has a battery cooling system
and a motor electrical cooling system. See
Under Hood Overview
(page 303). The
luggage compartment covers need to be
removed in order to access the reservoirs.
See
Installing and Removing the
Luggage Compartment Cover (page 277). When the electric motor is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 390).
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between
-29–-35°F (-34–-37°C).
Check coolant concentration using a
refractometer. We do not recommend the
use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant
It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the electric motor
cooling system. See
Cooling System
Capacity and Specification (page 344).
Do not mix different colors or types of
coolant in your vehicle. Mixing of coolants
or using an incorrect coolant may harm the
electric motor or cooling system
components and may cause damage that
the vehicle warranty may not cover.
Note: Automotive fluids are not
interchangeable.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the electric
motor cooling or heating systems.

CLEANING THE EXTERIOR
CLEANING THE EXTERIOR
PRECAUTIONS
Immediately remove fuel spillages, additive
residuals, bird droppings, insect deposits
and road tar. These may cause damage to
your vehicle
’s paintwork or trim over time.
Remove any exterior accessories, for
example antennas, before entering a car
wash.
CLEANING HEADLAMPS AND
REAR LAMPS
We recommend that you only use cold or
lukewarm water containing car shampoo
to clean the headlamps and the rear
lamps.
Do not scrape the lamps.
Do not wipe lamps when they are dry.
CLEANING WINDOWS AND WIPER
BLADES
To clean the windshield and wiper blades:
• Clean the windshield with a
non-abrasive glass cleaner.
Note: When cleaning the interior of the
windshield, avoid getting any glass cleaner
on the instrument panel or door panels.
Wipe any glass cleaner off these surfaces
immediately.
• Clean the wiper blades with washer
fluid or water applied with a soft
sponge or cloth.
Note: Do not use razor blades or other
sharp objects to clean or remove decals
from the inside of the heated rear window.
This can cause damage not covered by the
vehicle Warranty. CLEANING CHROME, ALUMINIUM
OR STAINLESS STEEL
We recommend that you only use a car
shampoo, a soft cloth and water on
bumpers and other chrome, aluminium or
stainless steel parts.
Note:
For additional information and
assistance, we recommend that you contact
an authorized dealer.
Note: Rinse the area well after cleaning.
Note: Do not use abrasive materials, for
example steel wool or plastic pads, as they
can scratch these surfaces.
Note: Do not use chrome cleaner, metal
cleaner or polish on wheels or wheel covers.
CLEANING WHEELS
Only use a recommended wheel and tire
cleaner to clean the wheels weekly. For
additional information and assistance, we
recommend that you contact an
authorized dealer.
1. Use a sponge to remove heavy deposits of dirt and brake dust.
2. Rinse well after cleaning.
Note: Do not apply a cleaning chemical to
warm or hot wheel rims and covers.
If you intend on parking your vehicle for an
extended period after cleaning the wheels
with a wheel cleaner, drive your vehicle for
a few minutes before parking your vehicle.
This reduces the risk of corrosion of the
brake discs, brake pads and linings.
Do not clean the wheels when they are hot.
Note: Some car washes could damage
wheel rims and covers.
Note: Using non-recommended cleaners,
harsh cleaning products, chrome wheel
cleaners or abrasive materials could

PREPARING YOUR VEHICLE
FOR STORAGE
If you plan on storing your vehicle for 30
days or more, read the following
maintenance recommendations to make
sure your vehicle stays in good operating
condition.
We engineer and test all vehicles and their
components for reliable, regular driving.
Under various conditions, long-term
storage may lead to degraded
performance or failure unless you use
specific precautions to preserve vehicle
components.
General
•
Store all vehicles in a dry, ventilated
place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and damage.
Body
• Wash your vehicle thoroughly to
remove dirt, grease, oil, tar or mud from
exterior surfaces, rear-wheel housing
and the underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
• Touch-up exposed or primed metal to
prevent rust.
• Cover chrome and stainless steel parts
with a thick coat of auto wax to prevent
discoloration. Re-wax as necessary
when you wash your vehicle.
• Lubricate all hood, door and luggage
compartment hinges and latches with
a light grade oil.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents. Cooling system
•
Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling
system leaks and that fluid is at the
recommended level.
Battery Systems
We recommend the following actions for
your vehicle:

case or power transfer unit failure.
Follow the recommended tire inflation
pressures found on the Safety
Compliance Certification label, or the
Tire Label on the B-Pillar or the edge of
the driver door. Failure to follow this
instruction could result in loss of vehicle
control, vehicle rollover, or personal injury
or death.
The tires on your vehicle could have
all-weather treads to provide traction in
rain and snow. In some climates you will
need to use snow tires and chains on your
vehicle in emergency situations or if
required by law.
Note: The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
Note: Driving too fast for road conditions
creates the possibility of loss of vehicle
control. Driving at very high speeds for
extended periods of time may result in
damage to vehicle components.
Note: Snow chains could damage
aluminum wheels.
Follow these guidelines when using snow
tires and chains:
• Use ultra low profile cables, 10 mm or
less in dimension as measured on the
sidewall of your tire, only with
225/60R18 all season tires.
• Do not use snow chains or cables with
225/55R19 or 245/45R20.
• Not all S-class snow chains or cables
meet the same restrictions. Chains of
this size restriction will include a
tensioning device.
• Purchase chains or cables from a
manufacturer that clearly labels body
to tire dimension restrictions. The snow
chains or cables must be mounted in
pairs on the rear tires only. •
When driving with snow chains do not
exceed 30 mph (50 km/h) or the
maximum speed recommended by the
chain manufacturer, whichever is less.
• Install cables securely, verifying that
the cables do not touch any wiring or
brake lines.
• Drive cautiously. If you hear the cables
rub or bang against the vehicle, stop
and retighten them. If this does not
work, remove the cables to prevent
vehicle damage.
• Remove the tire chains when they are
no longer needed. Do not use tire
chains on dry roads.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.

USING THE TIRE SEALANT
AND INFLATOR KIT
Tips for use of the kit
To ensure safe operation of the kit:
• Before operating the kit, make sure
your vehicle is safely off the road and
away from moving traffic.
• Do not remove any foreign objects,
such as nails or screws, from the tire.
• Do not allow the compressor to
operate continuously for more than 15
minutes. This will help prevent the
compressor from overheating.
• Only use the kit when the ambient
temperature is between -22°F (-30°C)
and 158°F (70°C).
• Only use the sealing compound before
the use-by date. The use-by date is on
a label on the sealant canister and can
be seen through the rectangular
viewing window on the bottom of the
compressor. Check the use-by date
regularly and replace the canister when
the sealant expires.
Note: Sealant compound contains latex.
Use appropriate precautions to avoid any
allergic reactions. When inflation only is required
for a tire or other objects, the
selector must be in the Air
position.
What to do when a tire is punctured
A tire puncture within the tire's tread area
can be repaired in two stages with the kit. •
In the first stage, the tire will be
reinflated with a sealing compound
and air. After the tire has been inflated,
you will need to drive the vehicle a
short distance approximately
4 mi
(6 km) to distribute the sealant in the
tire.
• In the second stage, you will need to
check the tire pressure and adjust, if
necessary, to the vehicle's specified
tire inflation pressure.
First Stage: Reinflating the Tire
with sealing compound and air WARNING:
Do not stand directly
over the kit while inflating the tire. If you
notice any unusual bulges or
deformations in the tire's sidewall during
inflation, stop and call roadside
assistance. WARNING:
If the tire does not
inflate to the recommended tire pressure
within 15 minutes, stop and call roadside
assistance.
Park the vehicle in a safe, level and secure
area, away from moving traffic.
Turn the hazard lights on. Apply the parking
brake and power off the vehicle. Inspect
the flat tire for visible damage.
If a puncture is located in the tire sidewall,
stop and call roadside assistance.
1. Remove the valve cap from the tire valve.
2. Unwrap the dual purpose hose (black tube) from the back of the compressor
housing.
3. Fasten the hose to the tire valve by turning the connector clockwise.
Tighten the connection securely.
