• The negative battery cable must
be removed first and installed last
when the battery is disconnected.
Disconnect the battery charger in the
following order:
1. Turn off the battery charger main
switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal.
• Always use a genuine HYUNDAI
approved battery when you replace
the battery.
By jump starting
After a jump start from a good battery,
drive the vehicle for 20-30 minutes
before it is shutoff. The vehicle may
not restart if you shut it off before the
battery had a chance to adequately
recharge. See “Jump Starting” in chapter
7 for more information on jump starting
procedures.
Information
An inappropriately disposed
battery can be harmful to
the environment and human
health. Dispose of the battery
according to your local law(s) or
regulations.
Reset Features
The following items may need to be reset
after the battery has been discharged or
the battery has been disconnected. See
chapter 3 or 4 for:
• Power Windows
• Trip Computer
• Climate Control System
• Clock
• Audio System
• Sunroof

Maintenance8-36
Tire Rotation
To equalize tread wear, HYUNDAI
recommends that the tires be rotated
according to the maintenance schedule
or sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pressure,
improper wheel alignment, out-of-
balance wheels, severe braking or severe
cornering. Look for bumps or bulges in
the tread or side of the tire. Replace the
tire if you find any of these conditions.
Replace the tire if fabric or cord is visible.
After rotation, be sure to bring the front
and rear tire pressures to specification
and check lug nut tightness (proper
torque is 79~94 lbf·ft [11~13 kgf·m]).
Without a spare tireWithout a spare tire
ODH073802ODH073802
Disc brake pads should be inspected for
wear whenever tires are rotated.
Information
Tires that are asymmetrical or directional
can only be installed on the wheel in
one direction. The outside and inside
of an asymmetrical tire is not easily
distinguishable. Pay careful attention to
the markings on the sidewalls of the tires,
noting the “outside” marking and also the
rotating direction before installing them
on the vehicle.
WARNING
• Do not use the compact spare tire for
tire rotation.
• Do not mix bias ply and radial ply
tires under any circumstances.
This may cause unusual handling
characteristics that may cause loss
of vehicle control resulting in an
accident.
Wheel Alignment and Tire
Balance
The wheels on your vehicle were aligned
and balanced carefully at the factory to
give you the longest tire life and best
overall performance.
In most cases, you will not need to have
your wheels aligned again. However,
if you notice unusual tire wear or your
vehicle pulling one way or the other, the
alignment may need to be reset.
If you notice your vehicle vibrating when
driving on a smooth road, your wheels
may need to be rebalanced.
NOTICE
Improper wheel weights can damage
your vehicle’s aluminum wheels. Use
only approved wheel weights.
