Emergency Towing
WARNING: If your vehicle has a
steering wheel lock make sure the
ignition is in the accessory or on position
when being towed.
If your vehicle becomes inoperable without
access to wheel dollies or a vehicle
transport trailer, it can be flat-towed with
all wheels on the ground, regardless of the
powertrain and transmission configuration,
under the following conditions:
• Your vehicle is facing forward for
towing in a forward direction.
• Place the transmission in neutral (N).
If you cannot shift the transmission into
neutral (N), you may need to override
the gear shifter. See
Transmission
(page 164). Failing to do so may result
in damage to the transmission.
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km).
Recreational Towing
You cannot recreational tow your vehicle
with all wheels on the ground because
vehicle or transmission damage could
occur. You must recreational tow your
vehicle with all four wheels off the ground
such as when using a car-hauling trailer.
Otherwise, you cannot recreational tow
your vehicle.

•
Do not warm up your vehicle on cold
mornings.
• Reduce the use of air conditioning and
heat.
• Avoid using speed control in hilly
terrain.
• Do not rest your foot on the brake
pedal while driving.
• Avoid carrying unnecessary weight.
• Avoid adding particular accessories to
your vehicle (e.g. bug deflectors,

racks).
• Avoid driving with the wheels out of
alignment.
COLD WEATHER
PRECAUTIONS
The functional operation of some
components and systems can be affected
at temperatures below approximately
-13°F (-25°C).
BREAKING-IN
Your vehicle requires a break-in period. For
the first 1,000 mi (1,600 km), avoid driving
at high speeds, heavy braking, aggressive
shifting or using your vehicle to tow. During
this time, your vehicle may exhibit some
unusual driving characteristics.
Ground Clearance
Since ground clearance is reduced, use
caution when approaching curbs or curb
stops from the front and rear as vehicle
damage may occur. Additionally, when
crossing speed bumps or driveway curbs,
you should approach at a 45 degree angle
to reduce the risk of vehicle damage. DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the front
rocker area of your vehicle. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.

TRANSPORTING THE VEHICLE
If you need to have your vehicle towed,
contact a professional towing service or,
if you are a member of a roadside
assistance program, your roadside
assistance service provider.
We recommend the use of a wheel lift and
dollies or flatbed equipment to tow your
vehicle. Do not tow with a slingbelt. We do
not approve a slingbelt towing procedure.
If you tow your vehicle incorrectly, or by
any other means, vehicle damage may
occur.
The rear wheels must be on a tow dolly
when towing your vehicle from the front
using wheel lift equipment. This prevents
damage to the transmission. The front wheels must be on a tow dolly
when towing your vehicle from the rear
using wheel lift equipment. This prevents
damage to the front fascia.

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. WARNING:
For vehicles with
Auto-Start-Stop the battery requirement
is different. You must replace the battery
with one of exactly the same
specification.
The battery is in the engine compartment.
See
Under Hood Overview (page 258).
Your vehicle has a maintenance-free
battery. It does not require additional
water during service.
If the vehicle battery has a cover and vent
hose, make sure you correctly install it after
cleaning or replacing the battery.
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 battery or terminals, remove
the cables from the terminals and clean
with a wire brush. You can neutralize the
acid with a solution of baking soda and
water.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.
Note: If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing. If you replace the battery make sure it
matches the electrical requirements of
your vehicle.
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.
Battery Management System
(If
Equipped)
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery
drain is detected, the system temporarily
disables some electrical systems to
protect the battery.
Systems included are:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
displays to alert you that battery
protection actions are active. These
messages are only for notification that an
action is taking place, and not intended to
indicate an electrical problem or that the
battery requires replacement.
After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time your vehicle must remain
fully locked with the ignition switched off.
