TOWING A TRAILER PRECAUTIONS
WARNING: Do not exceed the
GVWR or the GAWR specified on the
certification label. WARNING:
Towing trailers
beyond the maximum recommended
gross trailer weight exceeds the limit
of your vehicle and could result in
engine damage, transmission damage,
structural damage, loss of vehicle
control, vehicle rollover and personal
injury. WARNING:
Do not exceed the
lowest rating capacity for your vehicle
or trailer hitch. Overloading your
vehicle or trailer hitch can impair your
vehicle stability and handling. Failure
to follow this instruction could result
in the loss of control of your vehicle,
personal injury or death. WARNING: Do not cut, drill, weld
or modify the trailer hitch. Modifying
the trailer hitch could reduce the hitch
rating. WARNING:
The anti-lock brake
system does not control the trailer
brakes.
TRAILER BRAKE PRECAUTIONS WARNING:
Do not connect a trailer's
hydraulic brake system directly to your
vehicle's brake system. Your vehicle may
not have enough braking power and your
chances of having a collision greatly
increase. WARNING:
Do not tow a trailer fitted
with electric trailer brakes unless your
vehicle is fitted with a compatible
aftermarket electronic trailer brake
controller. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. For
additional information and assistance, we
recommend that you contact an authorized
dealer.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you install
them properly and adjust them to the
manufacturer's specifications. The trailer
brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined weight
rating.
Certain states require functioning trailer
brakes for trailers over a specified weight.
Be sure to check state regulations for this
specified weight.

WARNING: Keep batteries out of
reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or
clothing. Shield your eyes when working
near the battery to protect against possible
splashing of acid solution. In case of acid
contact with skin or eyes, flush immediately
with water for a minimum of 15 minutes and
get prompt medical attention. If acid is
swallowed, call a physician immediately. WARNING:
Use only adequately
sized cables with insulated clamps. WARNING: Make sure that the cables
are clear of any moving parts and fuel
delivery system parts. WARNING:
Connect batteries with
only the same nominal voltage. WARNING:
If the engine is running
while the hood is open, stay clear of
moving engine components. Failure to
follow this warning could result in serious
personal injury or death. Do not attempt to push-start an automatic
transmission vehicle. This could cause
transmission damage.
Do not disconnect the battery of the disabled
vehicle. This could damage your vehicle's
electrical system.
Preparing the Vehicle
Use only a 12 volt supply to start your vehicle.
Park the booster vehicle close to the hood
of the disabled vehicle, making sure the two
vehicles do not touch.
Jump Starting the Vehicle
Connecting the Jumper Cables
WARNING:
Do not connect the
negative jumper cable to any other part of
your vehicle. Use the ground point.
Note: If you are using a jump pack or booster
box, follow the manufacturer's instructions. 1. Pull the red rubber boot backward.
Connect the positive (+) jumper cable to
the positive (+) terminal of the discharged
battery.

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
for a period of time after you switch the
ignition off. This is to allow diagnostic and
adaptive tables to be stored. Disconnecting
the battery without waiting can cause
damage not covered by the vehicle
Warranty. 4. Disconnect the negative battery cable
terminal.
5. Disconnect the positive battery cable terminal.
6. Remove the battery securing clamp.
7. Remove the battery.
8. To install, reverse the removal procedure.
Note: Before reconnecting the battery, make
sure the ignition remains switched off.
Note: Make sure the battery cable terminals
are fully tightened.
Note: After cleaning or replacing the battery,
make sure you reinstall the battery cover or
shield.
If you disconnect or replace the vehicle
battery, you must reset the following
features:
• Window bounce-back. See Windows
(page 130).
• Clock Settings.
• Pre-set radio stations.
• Steering Angle Sensor. Note:
To calibrate the steering angle sensor,
drive the vehicle above
30 mph (50 km/h)
for a minimum of 1.2 mi (2 km). Make sure to
drive straight ahead for a minimum of 30
seconds. Several vehicle functions are
disabled and a warning light could appear
until the sensor is calibrated.
Battery Management System
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 of the following features:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
display to alert you that battery protection
actions are active.
